1766 - Henry Cavendish discovers hydrogen
As a chemist, one of his most important findings was the discovery of hydrogen. On February 23, 1765, Cavendish was able to isolate this element and discover its properties, as well as carbon dioxide and other gases. Through his experiments it was established that hydrogen is the lightest
1766 to the Royal Society. Subsequently, he discovered the composition of waterof the known gases
The results were published in the communication Factitious Airs, presented in 1766 to the Royal Society. He later discovered the composition of the natural water, stating that "it is composed of dephlogisticated air (oxygen) bound to phlogiston (hydrogen)".
1774 - Joseph Priestley discovers the oxygen and shows that the air is formed by different gases
Priestley's family moved to a house next to a brewery and he became interested in the gas bubbling in this company. This discovery occurred when heated HgO, mercury monoxide, with which it obtained two vapors, one is condensed in mercury droplets (Hg). To that gas he picked it up in a container, observing that it increased the brilliance of a flame and that if it introduced live mice, they became very active and lived longer. Priestley inhaled from this gas and felt comfortable. A this gas, called it dephlogisticated air, but it was oxygen by nature. He was the first person to use the oxygen mask. Priestley communicated his observations to the French chemist Antoine Laurent de Lavoisier, who repeated the experiments, thus demonstrating that he was in the air and in the water, pointing out his role in respiration and combustion

=== 1960 - Spandex fibers are synthesized ===
=== 1962 - Laser Diode ===
The first to demonstrate coherent light emission from a semiconductor diode (the first laser diode), is widely acknowledged to have been Robert N. Hall and his team at the General Electric research center in 1962.
=== 1962 - Polyimide resins are synthesized ===
=== 1962- William Armistead and S. Donald Stookey of Corning Glass Works invent light-sensitive (photochromic) glass. ===
Modern photochromic lenses tend to be plastic and instead of silver chemicals they contain organic (carbon-based) molecules called naphthopyrans that react to light in a slightly different way: they subtly change their molecular structure when ultraviolet light strikes them. In this altered form, they soak up more ordinary light as it tries to pass by (technically, we say they have a different absorption spectrum), which is what makes the lenses darken. Imagine lots of molecules suddenly darkening inside a clear lens. It's a bit like closing the blinds in front of your window on a sunny day: as the slats turn, they progressively block out more and more light.
=== 1962 - The first SQUID superconducting quantum interference device is invented ===
A SQUID (for superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions.
=== 1963 - The first balloon embolectomy catheter is invented by Thomas Fogarty. ===
Thomas Fogarty invented the "medical industry standard" balloon embolectomy catheter. Patented in 1963, this inflated balloon extraction technique revolutionized surgical embolectomy procedures. The Foley catheter is a rubber tube with a balloon tip named after it's inventor. After insertion into the bladder via the urethra, the tip is filled using a syringe with sterilized liquid or air, in order to keep the catheter in place. This type of catheter allows for continuous draining of the bladder, important during and after surgery.
=== 1963 - Ivan Sutherland develops Sketchpad, one of the first computer-aided design programs. ===
=== 1965 - A bulletproof nylon fabric, Kevlar, is invented at DuPont ===
Kevlar® or polyparaphenylene terephthalamide is a polyamide synthesized for the first time in 1965 by Polish-American chemist Stephanie Kwolek (1923-2014), who worked for DuPont. The obtaining of the fibers of Kevlar was complicated, emphasizing the contribution of Herbert Blades, that solved the problem of which solvent to use for the processing.
=== 1965 - Frank Pantridge develops the portable defibrillator for treating cardiac arrest patients. ===
=== 1965 - James Russell invents the compact disk ===
A compact disk (cd) is a popular form of digital storage media used for computer files, pictures, and music. The plastic platter is read and written to by a laser in a CD drive. It comes in several varieties including CD-ROM, CD-R, and CD-RW.
James Russell invented the compact disk in 1965. James Russell was granted a total of 22 patents for various elements of his compact disk system. However, the compact disk did not become popular until it was mass manufactured by Philips in 1980.

|'''Arthroscope introduced'''
{| class="wikitable"
|Advances in fiber-optics technology give surgeons a view into joints and other surgical sites through an arthroscope, an instrument the diameter of a pencil, containing a small lens and light system, with a video camera at the outer end. Used initially as a diagnostic tool prior to open surgery, arthroscopic surgery, with its minimal incisions and generally shorter recovery time, is soon widely used to treat a variety of joint problems.

{| class="wikitable"
|The introduction of digital seismology in oil exploration increases accuracy in locating underground pools of oil. The technique of using seismic waves to look for oil is based on determining the time interval between the sending of a sound wave (generated by an explosion, an electric vibrator, or a falling weight) and the arrival of reflected or refracted waves at one or more seismic detectors. Analysis of differences in arrival times and amplitudes of the waves tells seismologists what kinds of rock the waves have traveled through.

{| class="wikitable"
|Corning Glass Works scientists Donald Keck, Peter Schultz, and Robert Maurer report the creation of optical fibers that meet the standards set by Kao and Hockham. The purest glass ever made, it is composed of fused silica from the vapor phase and exhibits light loss of less than 20 decibels per kilometer (1 percent of the light remains after traveling 1 kilometer). By 1972 the team creates glass with a loss of 4 decibels per kilometer. Also in 1970, Morton Panish and Izuo Hayashi of Bell Laboratories, along with a group at the Ioffe Physical Institute in Leningrad, demonstrate a semiconductor laser that operates continuously at room temperature. Both breakthroughs will pave the way toward commercialization of fiber optics.

Known as Saad el Aali in Arabic, it impounds the waters of the Nile to form Lake Nasser, the world’s third-largest reservoir, with a capacity of 5.97 trillion cubic feet. The project requires the relocation of thousands of people and floods some of Egypt’s monuments and temples, which are later raised. But the new dam controls annual floods along the Nile, supplies water for municipalities and irrigation, and provides Egypt with more than 10 billion kilowatt-hours of electric power every year.

Five years later ''Pioneer 11'' makes its closest approach to Saturn, sending back images of the planet’s rings, and then heads out of the solar system in the opposite direction from ''Pioneer 10''. The last successful data acquisitions from ''Pioneer 10'' occur on March 3, 2002, the 30th anniversary of its launch date, and on April 27, 2002.

What are non-Newtonian materials?
Ketchup, nail polish, toothpaste, whipped cream, cornstarch, blood, face cream, silly-putty, paint, and custard—what do these things have in common? Apparently nothing! In fact, they're all examples of non-Newtonian fluids. In everyday terms, they get either more viscous (thicker and less runny) or less viscous (thinner and more runny) if you push and poke them around a bit. Some of them are shear-thinning (they get less viscous), others are shear-thickening (getting more viscous) when you push them about:
Shear thinning: Ketchup, toothpaste, blood, paint, nail polish, whipped cream, and face-cream start off relatively thick and viscous but become more runny if you subject them to forces.
Shear thickening: Cornstarch, custard, many soups, and silly-putty work the opposite way. They thicken up when you subject them to forces.
Some non-Newtonian materials are permanently changed by applied forces: custard stays thick, for example. Others are changed only temporarily and revert back to their original form when the force is removed. Ketchup thins when you shake it but thickens up again once it's sitting on your plate. Toothpaste thickens and thins repeatedly: it's thick inside the tube, thins and flows when you squeeze it, thickens back into a gel once it's sitting on your brush, and thins again when you brush it over your teeth

-Computers
A pioneering low-cost laptop for developing countries called OLPC is announced by MIT computing pioneer Nicholas Negroponte.
Over the last few years, they've worked to create a trimmed-down, low-cost laptop suitable for people who live in developing countries where electricity and telephone access are harder to find. Their project is known as OLPC: One Laptop Per Child.
What's different about the OLPC?
In essence, an OLPC computer is no different from any other laptop: it's a machine with input, output, memory storage, and a processor—the key components of any computer. But in OLPC, these parts have been designed especially for developing countries.
Here are some of the key features:
Low cost: OLPC was originally designed to cost just $100. Although it failed to meet that target, it is still cheaper than most traditional laptops.
Inexpensive LCD screen: The hi-tech screen is designed to work outdoors in bright sunlight, but costs only $35 to make—a fraction of the cost of a normal LCD flat panel display.
Trimmed down operating system: The operating system is like the conductor of an orchestra: the part of a computer that makes all the other parts (from the processor chip to the buttons on the mouse) work in harmony. Originally, OLPC used only Linux (an efficient and low-cost operating system developed by thousands of volunteers), but it began offering Microsoft Windows versions as an alternative in 2008.
Wireless broadband: In some parts of Africa, fewer than one person in a hundred has access to a wired, landline telephone, so dialup Internet access via telephone would be no use for OLPC users. Each machine's wireless chip will allow it to create an ad-hoc network with other machines nearby—so OLPC users will be able to talk to one another and exchange information effortlessly.
Flash memory: Instead of an expensive and relatively unreliable hard drive, OLPC uses a huge lump of flash memory—like the memory used in USB flash memory sticks and digital camera memory cards.
Own power: Home electricity supplies are scarce in many developing countries, so OLPC has a hand crank and built-in generator. One minute of cranking generates up to 10 minutes of power.
Is OLPC a good idea?
Anything that closes the digital divide, helping poorer children gain access to education and opportunity, must be a good thing. However, some critics have questioned whether projects like this are really meeting the most immediate needs of people in developing countries. According to the World Health Organization, around 1.1 billion people (18 percent of the world's population) have no access to safe drinking water, while 2.7 billion (a staggering 42 percent of the world's population) lack basic sanitation. During the 1990s, around 2 billion people were affected by major natural disasters such as floods and droughts. Every single day, 5000 children die because of dirty water—that's more people dying each day than were killed in the 9/11 terrorist attacks.
With basic problems on this scale, it could be argued that providing access to computers and the Internet is not a high priority for most of the world's poorer people. Then again, education is one of the most important weapons in the fight against poverty. Perhaps computers could provide young people with the knowledge they need to help themselves, their families, and communities escape a life sentence of hardship?

- 3D Television "3D TV starts to become more widely available."
There are several different ways of making a 3D TV, but all of them use the same basic principle: they have to produce two separate, moving images and send one of them to the viewer's left eye and the other to the right. To give the proper illusion of 3D, the left eye's image mustn't be seen by the right eye, while the right eye's image mustn't be seen by the left.
Anaglyph: You have to wear eye glasses with colored lenses so your brain can fuse together the partly overlapping red and cyan pictures on the screen.
Polarizing: You wear lenses that filter light waves in different ways so each eye sees a different picture.
Active-shutter: The left and right lenses of your glasses are fitted with liquid crystals that effectively "open" and "close" at high speed, in rapid alternation, so your two eyes view separate images (frames) shown on the same screen.
Lenticular: You don't need glasses with this system. Instead, a row of plastic lenses in front of the screen bends slightly different, side-by-side images so they travel to your left and right eyes. You must sit in the right place to see a 3D image.

'''Compound''': A group of 2 or more elements chemically combined.
==Covalent Compounds==
[[File:Sauerstoffmolekül Strukturformel.svg|thumb|The O<sub>2</sub> you breathe is a diatomic molecule.]]
A '''covalent compound''' is a compound that is made out of neutral components (all nonmetals, such as H<sub>2</sub>O, CO<sub>2</sub>, C<sub>12</sub>H<sub>12</sub>O<sub>12</sub>), has low melting and boiling points (often gases and liquids at room temperature), has covalent bonds (shared electrons), and exists as individual molecules. Exceptions are made to '''BRINClHOF''': Br<sub>2</sub>, I<sub>2</sub>, N<sub>2</sub>, Cl<sub>2</sub>, H<sub>2</sub>, O<sub>2</sub>, F<sub>2</sub>.
;Naming
#Count the number of atoms present of each nonmetal.
#Choose a Greek prefix:
{| class="wikitable"
|-
! Number !! Greek Prefix
|-
| 1 || Mono
|-
| 2 || Dri
|-
| 3 || Tri
|-
| 4 || Tetra
|-
| 5 || Penta
|-
| 6 || Hexa
|-
| 7 || Hepta
|-
| 8 || Octa
|-
| 9 || Nona
|-
| 10 || Deca
|}
Examples are...
*N<sub>2</sub>O<sub>5</sub>: '''Dinitrogen Pentaoxide'''
*CO: '''Carbon Monoxide'''
;Formulas
#Look at the Greek prefix.
#Assign the number and the elements attached.
Examples are...
*Dinitrogen Pentoxide - '''N<sub>2</sub>O<sub>5</sub>'''
*Carbon Monoxide - '''CO'''
==Ionic Compounds==
When you think of an '''ionic compound''', think of salts, such as NaCl, CaCO<sub>3</sub>, and KF. These compounds generally have a metal and one or more nonmetals. They have cations and anions and these two cancel each other out since the nuclear change must equal 0. They have high melting and boiling points and transfer electrons (ionic bonds). These exist as crystal lattices (the term, '''unit cell''', being the smallest crystal lattice).
{{note|Some compounds can be both covalent and ionic--the ionic compounds contain [[Talk:The periodic table/Periodic Trends|polyatomic ions]]. '''Polyatomic ions''' are groups of covalently bonded nonmetals which exist as ions.}}
There are two types of ionic compounds: '''Binary''' and '''Ternary'''. Binary ionic compounds consist of a metal and nonmetal, while ternary ionic compounds consist of a metal and polyatomic ion. There are also binary and ternary ionic compounds that have '''[[The_periodic_table#Transition_Metals|transitional metals]]''', and require roman numerals. Ternary ionic compounds with 2 polyatomic ions also exist as well.
EXCEPTIONS: Lead (Pb) and Tin (Sn) '''NEED ROMAN NUMERALS''' while Silver (Ag) and Zinc (Zn) '''DO NOT NEED ROMAN NUMERALS''' as their charge is always +1 and +2, respectively.
===Binary Ionic Compounds===
;Naming

The polyatomic cation has to be ammonium (NH<sub>4</sub>). Name the ammonium, then the polyatomic ion.
==Acids==
'''Acids''' always have an <big>H</big> in front of them; so it is easy. Examples are '''HCl, HBr, HClO<sub>4</sub>'''.
===Binary Acids===
'''Binary Acids''' always have an <big>H</big> in front of them and are followed by a '''nonmetal''' (hydroanionic acid).
===Ternary Acids===
'''Ternary Acids''' do not have a <big>hydro prefix</big> in front of them (but they do have an '''H'''). You have to know your polyatomic ions in order to master the acids:
*If the polyatomic ion ends in '''-ate''', the acid will end in '''-ic'''.
*If the polyatomic ion ends in '''-ite''', the acid will end in '''-ous'''.
*If the polyatomic ion ends in '''-ide''', the acid will be named '''hydroanionic acid'''.
{{note|Here is a great saying for you to remember this: I '''ate''' something '''ic'''ky. Don't b'''ite''' '''-ous'''}}
Examples are...
*'''HCl''' - Hydrochloric acid
*'''HBr''' - Hydrobromic acid
*'''HF''' - Hydroflouric acid
*'''HNO<sub>3</sub>''' - Nitric acid
*'''HNO<sub>2</sub>''' - Nitrous acid
*'''HPO<sub>3</sub>''' - Phosphorous acid
*'''HCN''' - Hydrocyanic acid
==Bases==
Bases always have an '''OH<sup>-1</sup>''' in front of them as the anion. This is known as the '''hydroxide'''.
;Naming
Examples are...
*'''KOH''' - Potassium hydroxide
*'''Ca(OH)<sub>2</sub>''' - Calcium hydroxide
*'''Fe(OH)<sub>2</sub>''' - Iron (II) hydroxide
;Formula

#Cross the oxidation number of the cation to the hydroxide
Examples are...
*Strontium hydroxide - '''Sr(OH)<sub>2</sub>'''
*Manganese (II) hydroxide - '''Mn(OH)<sub>2</sub>'''
==Hydrates==
Hydrates are made up of a '''salt and a H<sub>2</sub>O''' (water molecule).

==Overview==
* Explores the psychology of core [[emotion]]s – what are the criteria for an emotion and what are the core emotions?
* The "emotion sort" class exercise involves collectively sorting hundreds of emotion words to linguistically model underlying families or clusters of emotional experience
* Discusses "emotion knowledge" as a component "emotional intelligence" and considers "linguistic relativism", the idea that language shapes experience
==Criteria==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
==Non-emotions==
If an affective experience does not constitute an emotion, it could instead be a(n):
# Attitude (e.g., hate)
# Behaviour (e.g., aggression)
# Cognition (e.g., confused)
# Disorder (e.g., depression, behavioural conduct disorder)
# Mood (e.g., grumpy)
# Personality trait (e.g., neuroticism)
==Core emotions==
What are the core emotions?
Theoretical models typically identify about six to eight core emotions, usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Linguistic models of emotion are developed from analysis of language (words) used to describe different affective states.
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

== Foreign emotion words==
[[File:Non-English emotion words exercise.png|400px|thumb|Non-English emotion words and definitions suggested by a class in 2023.]]

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020). For a deeper dive, see the work of [https://scholar.google.com/citations?hl=en&user=KYOCMe0AAAAJ&view_op=list_works&citft=1&email_for_op=JamesTNeill%40gmail.com&gmla=AJsN-F6j5ww5q8q1NDhd-S-S5TKin27AiS2FjfdcUfkAVXE5YmU8yO2AKhpvl4zVnK9DydZiplyaDTbSiR07LuIndWHHRf5kRoyKUzi4uOkOI-xZ4Kf2XVza_DPjHMCvHpGTvzzzwuEddowKzs8IaU-p8KmARjs-EPENQ-8nNkxQMzms7CDipXgQXAQje0klOsKdU-tMXPC8MfCd-AI381ZWZ14SE60TcAYDsJMkNswaSvgjOQ10Yn-JJz8LV86D7NuLTSukCsSe James Pennebaker] (Google Scholar).

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.

What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020).

==Overview==
* Explores the psychology of core [[emotion]]s – what are the criteria for an emotion and what are the core emotions?
* The "emotion sort" class exercise involves collectively sorting hundreds of emotion words to linguistically model underlying families or clusters of emotional experience
* Discusses "emotion knowledge" as a component "emotional intelligence" and considers "linguistic relativism", the idea that language shapes experience
==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core emotions?
Theoretical models typically identify about six to eight core emotions, usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Linguistic models of emotion are developed from analysis of language (words) used to describe different affective states.
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}

* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020).

* Discusses "emotion knowledge" as a component "emotional intelligence" and considers "linguistic relativism", the idea that language shapes experience
==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

==Emotion knowledge==

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process.

==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

==Emotion knowledge==

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020).

==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

==Emotion knowledge==

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020).

==Overview==
* Explores the psychology of core [[emotion]]s–what are the criteria for an emotion and what are the core emotions?
* The "emotion sort" class exercise involves collectively sorting hundreds of emotion words to linguistically model underlying families or clusters of emotional experience
* Discusses "emotion knowledge" as a component "emotional intelligence" and considers "linguistic relativism", the idea that language shapes experience
==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

==Emotion knowledge==

[[File:Emotions wheel.png|thumb|right|450px|'''Emotions wheel''' showing aspects of seven core emotions]]
What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020). For a deeper dive, see the work of [https://scholar.google.com/citations?hl=en&user=KYOCMe0AAAAJ&view_op=list_works&citft=1&email_for_op=JamesTNeill%40gmail.com&gmla=AJsN-F6j5ww5q8q1NDhd-S-S5TKin27AiS2FjfdcUfkAVXE5YmU8yO2AKhpvl4zVnK9DydZiplyaDTbSiR07LuIndWHHRf5kRoyKUzi4uOkOI-xZ4Kf2XVza_DPjHMCvHpGTvzzzwuEddowKzs8IaU-p8KmARjs-EPENQ-8nNkxQMzms7CDipXgQXAQje0klOsKdU-tMXPC8MfCd-AI381ZWZ14SE60TcAYDsJMkNswaSvgjOQ10Yn-JJz8LV86D7NuLTSukCsSe James Pennebaker] (Google Scholar).

==Overview==
* Explores the psychology of core [[emotion]]s–what are the criteria for an emotion and what are the core emotions?

==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:

What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020). For a deeper dive, see the work of [https://scholar.google.com/citations?hl=en&user=KYOCMe0AAAAJ&view_op=list_works&citft=1&email_for_op=JamesTNeill%40gmail.com&gmla=AJsN-F6j5ww5q8q1NDhd-S-S5TKin27AiS2FjfdcUfkAVXE5YmU8yO2AKhpvl4zVnK9DydZiplyaDTbSiR07LuIndWHHRf5kRoyKUzi4uOkOI-xZ4Kf2XVza_DPjHMCvHpGTvzzzwuEddowKzs8IaU-p8KmARjs-EPENQ-8nNkxQMzms7CDipXgQXAQje0klOsKdU-tMXPC8MfCd-AI381ZWZ14SE60TcAYDsJMkNswaSvgjOQ10Yn-JJz8LV86D7NuLTSukCsSe James Pennebaker] (Google Scholar).

{{Motivation and emotion/Tutorials|Tutorial 7: Core emotions|seventh}}
{{Motivation and emotion/Tutorials/Complete2}}
<!-- {{Motivation and emotion/Tutorials/Complete2}} -->
<!-- {{Motivation and emotion/Tutorials/In development}} -->
==Overview==
* Explores the psychology of core [[emotion]]s–what are the criteria for an emotion and what are the core emotions?
* The "emotion sort" class exercise involves collectively sorting hundreds of emotion words to linguistically model underlying families or clusters of emotional experience
* Discusses "emotion knowledge" as a component "emotional intelligence" and considers "linguistic relativism", the idea that language shapes experience
==Criteria for core emotions==
What are the criteria for a core emotion?
To be classified as a core or basic emotion, the affective state should exhibit each of the following criteria:
# Distinct antecedent casual trigger (provokes by same circumstances each time)
# Inescapable (inevitable) activation
# Rapid onset
# Distinct pattern of physiology (e.g., pattern of brain activity, heart-rate)
# Automatic (unlearned) appraisal
# Distinct subjective experience (feeling state)
# Distinct cognition (thoughts, images, and memories)
# Distinct expression (facial and body)
# Brief duration (short-lived)
# Universal presence in other cultures and primates
The exact number and nature of such criteria vary between theorists.
==Non-emotions==
Not all affective experiences (i.e., feelings) represent core human emotions.
If an affective experience does not constitute an emotion, it could instead be a(n):
# [[w:Attitude (psychology)|Attitude]] (e.g., hate)
# [[w:Behavior|Behaviour]] (e.g., aggression)
# [[w:Cognition|Cognition]] (e.g., confused)
# [[w:Mental disorder|Disorder]] (e.g., depression, behavioural conduct disorder)
# [[w:Mood (psychology)|Mood]] (e.g., grumpy)
# [[w:Trait theory|Personality trait]] (e.g., neuroticism)
==Core emotions==
What are the core human emotions?
Theoretical models typically identify about six to eight core emotions (Reeve, 2024), usually including:
# Fear
# Anger
# Disgust
# Sadness
# Interest
# Joy
# Surprise
# Contempt
==Emotion sort exercise==
Models of emotion can be developed from analysis of language (words) used to describe different affective states (e.g., Ortony et al., 1987).
The goal of this exercise is to organise many (250+) [[Motivation and emotion/Tutorials/Emotion/List|emotion-related words]] into core emotion families:
{{anchor|Activity}}{{RoundBoxTop|theme=10}}

# Each person selects an emotion word and classifies it as either a:
## core emotion (and allocates it to a core emotion family)
## non-emotion (and indicates the reason it doesn't qualify as an emotion)
# Classifications can be changed if you disagree
# Repeat until all words are classified—a progress bar will be displayed
# If unsure, use chat or the comments column
# Discuss the:
#* experience of categorising: e.g., what was like? easy? hard? why?
#* unusual/unknown words or emotions you'd like to share or want to know more about?
#* results based on data analysis about:
#** % classified as emotions or not emotions
#** which emotion families were most popular and which words were allocated to each emotion family
#** which reasons were most used for excluding affective states as emotions

==Emotion knowledge==
[[File:Bananas by cactus cowboy.svg|thumb|right|175px|'''Schadenfreude''' (pronounced shar-den-frood-ar) is a German word for pleasure that arises from the misfortune of others (e.g., laughing when someone slips on a banana peel).]]
[[File:Emotions wheel.png|thumb|right|450px|'''Emotions wheel''' showing aspects of seven core emotions]]
What is emotion knowledge?
Emotion knowledge is part of [[#Emotional intelligence|emotional intelligence]].
Emotion knowledge refers to the library or vocabulary of distinct emotion concepts (represented by words) that a person has access to. The bigger the library, the more chance there is of being able to distinguish between subtle shades and nuances of emotional states (e.g., various flavours of anger or joy):
{{quote|"the finer and more sophisticated one's emotion knowledge is, the greater his or her capacity to respond to each life event with a specialised and highly appropriate reaction" (Reeve, 2009, p. 353).}}
Emotion knowledge can be improved, in part, by expanding one's linguistic repertoire for describing emotions.
==Emotional intelligence==
# What is [[Emotional intelligence|emotional intelligence]]?
##One of several [[w:Theory of multiple intelligence|multiple intelligence]]ss proposed by Gardener (1983)
##Also known as emotional quotient (EQ)
##[[Emotion knowledge]] or [[w:Emotional literacy|emotional literacy]] are components of emotional intelligence
# Goleman's (1995) conceptualisation of emotional intelligence suggested four aspects, based on awareness/management and self/other distinctions (see Table 1).
# Criticism: The term "intelligence" implies a fixed, steady state, however the four aspects of emotional intelligence are learnable and trainable, such as in school and the workplace.
# How can emotional intelligence be trained or enhanced?

Many varieties, shades, subtleties, and nuances of emotion are not so well described in English, but are well captured in some of the other 7,000 human languages.
Some of these words are imported to English and are known as [[w:Loanword|loanwords]] or borrowed words. For example, [[wikt:schadenfreude|schadenfreude]] (German for the pleasure derived from the misfortune of others) can be found in the English dictionary. However, there remain many recognisable affective states for which there is no English equivalent or commonly adopted loanword.
{{anchor|Words}}
What words from other languages describe unique types of emotion? Share an example (word, definition, and language), based on your language knowledge or by [[/Non-English emotion words|exploring this list]]).
==Linguistic relativity==
What are the psychological implications of our emotion knowledge? For example, the [[w:Linguistic relativity|Sapir-Whorf hypothesis]] (linguistic relativity) argues that language enables experience. According to this [[w:Essentialism|essentialist]] view, our emotional vocabulary enables but also limits our capacity for emotional experience. In other words, our consciousness and experience is determined by our language. Therefore, expanding our language, can expand our emotional experience.
So, linguistic relativity implies that we can enrich our emotional lives by expanding our emotional vocabulary and incorporating more non-English emotion words.
There are two forms of linguistic relativity:
* '''Linguistic determinism''' (strong form): This claims that language completely controls and limits what you are able to think. Contemporary linguists and researchers have largely rejected this extreme view.
* '''Linguistic influence''' (weak form): This proposes that our native language guides our attention, shapes cognitive habits, and makes certain concepts easier to process. Modern research supports this weaker version (e.g., see Vine et al., 2020). For a deeper dive, see the work of [https://scholar.google.com/citations?hl=en&user=KYOCMe0AAAAJ&view_op=list_works&citft=1&email_for_op=JamesTNeill%40gmail.com&gmla=AJsN-F6j5ww5q8q1NDhd-S-S5TKin27AiS2FjfdcUfkAVXE5YmU8yO2AKhpvl4zVnK9DydZiplyaDTbSiR07LuIndWHHRf5kRoyKUzi4uOkOI-xZ4Kf2XVza_DPjHMCvHpGTvzzzwuEddowKzs8IaU-p8KmARjs-EPENQ-8nNkxQMzms7CDipXgQXAQje0klOsKdU-tMXPC8MfCd-AI381ZWZ14SE60TcAYDsJMkNswaSvgjOQ10Yn-JJz8LV86D7NuLTSukCsSe James Pennebaker] (Google Scholar).
==Beyond language==
[[File:Twemoji13 1f92e.svg|right|173px|thumb|Emojis are used to help communicate emotional reactions and experiences.]]
* Besides words, how else do we represent, understand, and communicate our emotions? For example:

|{{anchor|Einstein 1905}}In 1905<ref name=einstein05 /> he showed that a clock moving on a round-trip away from A and back along a polygonal or curved path, is retarded with respect to a clock stationary at A by approximately <math>\tfrac{1}{2}t(v/V)^{2}</math> at reunion. For example, a clock on the equator is retarded with respect to a clock on the pole. He described this consequence as being "peculiar" (German: eigentümlich).
{{anchor|Einstein 1911-HU}}In a lecture given on January 1911<ref name=einstein11a /> (published in November), he extended this "funny" (German: drollig) experiment to living organisms:

B. einen lebenden Organismus in eine Schachtel hineinbrächten und ihn dieselbe Hin- und Herbewegung ausführen lassen wie vorher die Uhr, so könnte man es erreichen, dass dieser Organismus nach einem beliebig langen Fluge beliebig wenig geändert wieder an seinen ursprünglichen Ort zurückkehrt, während ganz entsprechend beschaffene Organismen, welche an den ursprünglichen Orten ruhend geblieben sind, bereits längst neuen Generationen Platz gemacht haben. Für den bewegten Organismus war die lange Zeit der Reise nur ein Augenblick, falls die Bewegung annähernd mit Lichtgeschwindigkeit erfolgte!

To the moving organism, the long journey was only a moment if the movement happened close to the speed of light!

Lämmel in December 1920 (published 1921)<ref name=lammel2 /> again alluded to Einstein's lectures in Zürich (possibly the one from 1911, and maybe also later ones), describing a discussion between himself and Einstein. After Einstein concluded that the travelers who came back after their journey will probably meet their former contemporaries as old men while they themselves could have been away for only a few years, Lämmel objected that this conclusion is only drawn with respect to rods and clocks, but not with respect to living beings. Einstein responded though, that all processes in the blood, in the nerves etc. are eventually periodical oscillations, i.e. motions. Yet to any such motion the relativity principle applies, thus the conclusion regarding the unevenly rapid aging it permissive.
{{Lorentzbox|Text=While the official publication of Einstein's January lecture ({{slink||Einstein 1911-HU}}) mentions the aging of organisms, Lämmel recalls the reference to the aging of a human space traveler ("observer returning from a great journey into space"). This means that Einstein was the first to use human beings in the clock/twin paradox on January 16 which was first published by Lämmel on April 28, 1911. In comparison, {{slink||Langevin 1911-HU}} used space travelers in a lecture on April 10 with publication in July, and {{slink||Wiechert 1911-HU}} used space travelers in lectures held between March 25 and May 23 with publication in July/September. It seems very unlikely that before April 28, Lämmel became somehow aware of the content of Langevin's or Wiechert's lectures held a few weeks earlier, in order to use them in his description of Einstein's lecture.}}

He demonstrated that a moving radioactive sample of radium is less evolved and less aged and therefore more active at return then the ones that remained in the laboratory. He also used light signals and the Doppler effect to visualize the effect. The most famous part concerned his description of the aging of human space travelers:

Il suffirait pour cela que notre voyageur consente à s’enfermer dans un projectile que la Terre lancerait avec une vitesse suffisamment voisine de celle de la lumière, quoique inférieure, ce qui est physiquement possible, en s’arrangeant pour qu’une rencontre, avec une étoile par exemple, se produise au bout d’une année de la vie du voyageur et le renvoie vers la Terre avec la même vitesse. Revenu à la Terre ayant vieilli de deux ans, il sortira de son arche et trouvera notre globe vieilli de deux cents ans si sa vitesse est restée dans l’intervalle inférieure d’un vingt-millième seulement à la vitesse de la lumière.

For this it is sufficient that our traveler consents to be locked in a projectile that would be launched from Earth with a velocity sufficiently close to that of light but lower, which is physically possible, while arranging an encounter with, for example, a star that happens after one year of the traveler's life, and which sends him back to Earth with the same velocity. Returned to Earth he has aged two years, then he leaves his ark and finds our world two hundred years older, if his velocity remained in the range of only one twenty-thousandth less than the velocity of light. The most established experimental facts of physics allow us to assert that this would actually be so.

In his vehicle the centrifugal force will act on him in such a way, that in accordance with the relativity laws it will appear to be equal to the force of gravity acting upon the inhabitants of Earth. Thus the acting forces are only thus big, in order to give our fantasy the possibility to imagine the traveler as a human being. Since we have <math>\sqrt{1-v^{2}/c^{2}}</math> throughout, proper time flows four times slower for the traveler than for the inhabitants of the stars. Thus when he comes back to our solar system after 100 of our years, he will feel to have aged only by about 25 years. If he reaches an age of 75 years according to the development of his body and his own time experience, then this corresponds to a threefold return to our solar system, i.e. 300 of our Earth years.

That means in the judgment of the remaining one, the other one would never become old. Then the lecturer [i.e. Einstein] was asked in the discussion: "And if he comes back to his starting point on a curved travel path?", to which Einstein replied in full earnest: "Then in our judgment he would remain as young as he was at departure, even if we remaining ones became men with white beards in the meantime, the equations unshakably give the same result in every direction of motion, also for curved motion".

|In 1920 (published 1921),<ref name=wiechert20 /> Wiechert explained how to completely remove acceleration from the round-trip experiment: Bodies A, B, C move undisturbed and non-accelerated in different directions. A and B pass each other at time (1), B and C pass each other at a later time (2), and C and A finally pass each other at an even later time (3). So in this setup, the condition of C is the continuation of the condition of B. On any of the three bodies one can count the oscillations of light of a certain spectral-line, in which case relativity predicts that the ''combined sum of all oscillations'' on B+C is smaller than the number of oscillations on A alone. Wiechert also held that one can replace the light oscillations by the life functions of human-like beings which live on A, B and C. For instance, while the inhabitants of B+C only had time for one meal, there were arbitrarily many generations on A who follow after each other by death and birth.

In 1921 (published 1922),<ref name=wiechert21 /> Wiechert extended his previous acceleration-free round-trip experiment to an arbitrary number of non-accelerated bodies <math>B_{1}</math>, <math>B_{2}</math>, ..., which constitutes a "relay" (German: Stafette) starting from body A and back again. The first B passes A and moves away, and after some time the last B comes back to A. Since any B body continues the fate of the previous one, all bodies <math>B_{1}</math>, <math>B_{2}</math>, ..., combined have emitted fewer oscillations than A alone during the relay race. Wiechert pointed out that instead of light oscillations one can also choose the aging of life forms.
{{Lorentzbox|Text=Such relay experiments were later independently rediscovered in English language papers<ref name=debs group=S /> such as by Lange (1927)<ref group=S name=lange /> in which the brothers synchronize their times when they pass each other (“three brother experiment”).}}

==Acceleration as asymmetry indicator==
While it was known that any direct influence of [[w:proper acceleration]] on clocks can be neglected in the computation of the inertial frame of the stay-at-home twin (see previous section {{slink||Negligibility of proper acceleration}}), the very fact that only one of them is accelerating is still useful as an asymmetry argument in order to show that there is no contradiction to the relativity principle.

In a discussion from 1922,<ref name=morand /> Einstein is reported to have said that there is no contradiction in the round-trip experiment (in terms of a train leaving the station and returning later): The relativity principle is not applicable to this case, because the train is not in a Galilean system (i.e. inertial frame) any longer during the period of velocity change at turnaround, i.e. the ensemble of two frames having velocities in opposite direction is not an inertial frame. There is no reciprocity between a frame that changes direction and one that doesn't.

==Frame distribution as asymmetry indicator==
Because any direct influence of proper acceleration on the traveling clock at turnaround can be neglected (see {{slink||Negligibility of proper acceleration}}), the importance of {{slink||Acceleration as asymmetry indicator}} is limited to the mere fact that it reveals that only the traveler was in a non-inertial frame as only he changed his inertial frames, thus instead of emphasizing the occurrence of proper acceleration at turnaround, it's possible to describe the asymmetry more geometrically by emphasizing the different distribution of inertial frames of the twins along their worldlines.

|{{anchor|Einstein 1916-EP}}In a lecture from 1916,<ref name=einstein16 /> of which only an abstract was published, Einstein spoke about the "clock paradox of special relativity from the standpoint of [[w:general relativity]]."
{{anchor|Einstein 1918a-EP}}In a letter from September 1918,<ref name=einadl /> Einstein showed that general relativity makes the inertial frame K and and the accelerated frame K' of the clocks in the round-trip experiment "equally justified", explaining the time difference in K' by combining the influence of velocity and gravitational potential on clocks.
{{anchor|Einstein 1918-EP}}In his famous "Dialog about Objections against the Theory of Relativity" from November 1918,<ref name=einstein18 /> aimed at clarifying misconceptions of the clock paradox, he explained that there is no paradox in special relativity because there is no symmetry between clock U1 at rest in inertial frame K and clock U2 at rest in accelerated frame K' (see {{slink||Einstein 1918-AC}}). Yet [[w:general relativity]] and the [[w:equivalence principle]] allow the treatment of this problem also from the standpoint of frame K', where clock U2 remains at rest all of the time while U1 makes the following movements: (1) It is accelerated by a homogeneous gravitational field in the negative direction, (2) it moves with constant velocity <math>-v</math>, (3) it is accelerated in the positive direction until it turns around and comes by with constant velocity <math>+v</math>, (4) it moves with velocity <math>+v</math>, (5) it is accelerated in the negative direction until it stops. Clock U1 is retarded with respect to U2 in periods 2) and 4) due to velocity time dilation, but this retardation is overcompensated by the faster rate of U1 during period 3), because U1 is at a higher gravitational potential. He argued that the computation (which he didn't provide) shows that the advance of U1 in period 3) is double its retardation during periods 2) and 4). Einstein concluded that by this consideration "the paradox is completely resolved". Using [[w:Mach's principle]], he pointed out that the gravitational field in K' might be induced by the masses of the universe that are accelerated in this frame.
{{anchor|Einstein 1918b-EP}}In a letter to Einstein from December 1918, [[w:Max Jakob|Jakob]] doubted the result that the advance in period 3) is double the retardation during periods 2) and 4). Einstein responded by letter,<ref name=einstein18b /> in which he used the gravitational time dilation factor <math>1+\Phi/c^{2}</math> in K' in order to show that U1 at distance <math>l</math> is advancing by <math>\Phi/c^{2}=2vl/c^{2}</math> in period 3), which is indeed the double of approximated delay <math>vl/c^{2}</math> caused by velocity time dilation during periods 2) and 4).
{{anchor|Einstein 1921-EP}}Einstein is reported to have said in an interview from 1920,<ref name=einstein20 /> that while acceleration explains the age difference between the stationary twin B and the traveling twin A in terms of special relativity (see {{slink||Einstein 1920-AC}}), the "proper" description in terms of general relativity is as follows:

He described the round-trip experiment by using two platforms K (clock A) and K' (clock B) each equipped with rows of clocks. He first demonstrated the symmetry of time dilation and the mutual relativity of simultaneity on the platforms and its effect on clock synchronization. The K clocks that B passes are all advanced because of <math>t'=\gamma\left(t-vx/c^{2}\right)</math>, and the same is true after turnaround since only the direction of velocity has to be changed in the Lorentz transformation <math>t'-t'_{0}=\gamma\left(t+vx/c^{2}\right)</math> leading to the effect of clock desynchronization, where <math>t'_{0}</math> is a constant depending on which clock one uses as standard for the new synchronization. He graphically showed using Minkowski diagrams, that this simultaneity jump due to desynchronization amounts to double the velocity time dilation during the inertial phases, explaining why A is more advanced than B at reunion.

This implies that he (like Berg) believed that special relativity predicts ''equal'' clock times at reunion if the moving clock would have been left ''unregulated'' during the round-trip.
b) Lehmann's mistake (similar to Berg) seems to based on the fact, that in his paper he generally described time dilation and length contraction of special relativity as only being "apparent" as opposed to Lorentz's theory.}}

|colspan=2| Even though he correctly derived differential clock aging in the round-trip experiment, he (like Berg and Lehmann) claimed that effects like time dilation are "apparent" if one admits Einstein's "unconditional" relativity principle in which there is no aether and all "strides" (i.e. non-accelerated motions) are physically equivalent, but they are "real" if one admits the existence of an aether in the framework of a "conditional" relativity principle in which all strides are physically non-equivalent or anisotropic. This led him to the following interpretation of the clock paradox:
|-
| style="padding: 0px 20px 0px 20px;" |[...] so muß am Schluß des Versuches B in seinem Fortschritt gegenüber A im Verhältnis <math>1:\sqrt{1-u^{2}/c^{2}}</math> zurückgeblieben sein. Und dieses Zurückbleiben ist unbedingt reell, denn die beiden Gebilde A und B können ja unter gleichen Umständen unmittelbar beieinander verglichen werden. Hier ist es ganz sicher ausgeschlossen, an einen Schein zu glauben, der durch unsere Auffassung der Zeit bewirkt wird. So ist denn also auch die Folgerung unabwendbar, daß für den Verlauf der Weltvorgänge die Schreitungen nicht gleichwertig sind, ''und damit sind wir von neuem zu einem Schluß gekommen, welcher der Unbedingtheit des Relativitätsprinzipes durchaus widerspricht.'' [...] Man kann den Versuch noch mannigfach variieren, z. B. so, daß A ebenso wie B zwei verschiedene Schreitungen, <math>+u</math> und <math>-u</math>, nacheinander inne hat. Wird dann zu A der Wert <math>u_{1}</math>, zu B der Wert <math>u_{2}</math>, zugeordnet, so muß der Vergleich von A und B am Schluß des Versuches ergeben, daß B oder A in seinem Fortschritt zurückgeblieben erscheint, je nachdem die Schreitungen <math>+u_{1}</math>, <math>-u_{1}</math>, oder <math>+u_{2}</math>, <math>-u_{2}</math> weiter auseinanderliegen. ''Vielleicht ist gerade diese Formulierung des Satzes besonders geeignet, um die Ungleichwertigkeit der verschiedenen Schreitungen klar und deutlich zu zeigen.''
| style="padding: 0px 20px 0px 20px;" | [...] thus B's progress must be retarded with respect to A's in the ratio <math>1:\sqrt{1-u^{2}/c^{2}}</math> at the end of the experiment. And this retardation is definitely real, since both bodies A and B indeed can be immediately compared side by side under the same conditions. Here it is certainly excluded to believe that this is an appearance due to our conception of time. Thus the consequence is unavoidable too, that the strides are not equivalent in the course of the world processes, ''and therefore we again came to a conclusion that completely contradicts the unconditionality of the relativity principle.'' [...] One can vary this experiment in many ways, for instance, so that A in the same way as B successively undergoes two different strides <math>+u</math> and <math>-u</math>. If we apply the value <math>u_{1}</math> to A and <math>u_{2}</math> to B, then the comparison of A and B at the end of the experiment must give the result, that B or A is retarded in its progress depending on whether the strides <math>+u_{2},-u_{2}</math> or <math>+u_{1},-u_{1}</math> are further apart. ''Probably it is precisely this formulation of the theorem that is particularly suitable to demonstrate the non-equivalence of the different strides clearly and explicitly.''

|colspan=2|{{Lorentzbox|Text=a) So Campbell claims that any time difference during the outbound path is wiped out during the inbound path. His mistake is obvious: He is confusing coordinate differences stemming from the Lorentz transformation of ''events'' (which indeed depend on position and direction) with differences in ''clock aging'' derived from the proper time integral (which is ''accumulative'' and independent of position and direction.)
b) As Campbell's paper was a reply to Wiechert, it's interesting to compare them: Campbell was correct in dismissing the aether but wrong in denying asymmetric aging, while Wiechert was correct in deriving asymmetric aging but wrong in requiring the aether.

==Einstein's contributions==
1905:<ref name=einstein05 /> Introduction of the "peculiar" (German: eigentümlich) round-trip experiment with clocks in terms of a polygonal path as well as a continuously curved path, and an experiment comparing a clock at the pole with one at the equator.
January 1911 (published November):<ref name=einstein11a /> In a lecture from January, Einstein extended the "funny" (German: drollig) round-trip experiment to living organisms. According to [[w:Rudolf Lämmel]] in April 1911<ref name=lammel /> and [[w:Fritz Müller-Partenkirchen|Fritz Müller]] in October 1911,<ref name=muller /> Einstein spoke of human beings as well.
January 1911 (published January 1912):<ref name=einstein3 /> During a discussion with Einstein directly after the previous lecture, [[w:Fritz Müller-Partenkirchen|Fritz Müller]] claimed that any time difference during the round-trip should vanish at reunion, in analogy to the fact that the Lorentz contraction of a moving rod vanishes when it is at rest again. Einstein showed that the analogy is incorrect: While the clock rates are indeed the same again when they are mutually at rest, the clocks do not indicate the same time at reunion because "clocks are carriers of the time differential"; he went on to show that any possible influence of acceleration during the turnaround can be made negligible by elongating the constant velocity periods.
1912:<ref name=einst12manu /> In an unpublished manuscript on special relativity, Einstein showed that if system <math>\Sigma'</math> makes a round-trip along a polygon, then its inner processes will be retarded with respect to resting system <math>\Sigma </math> at reunion. He pointed out that any influence of acceleration can be neglected if one makes the time of acceleration negligible with respect to the total time of motion along the polygon.
April 1914:<ref name=einstpetz /> [[w:Joseph Petzoldt]] criticized asymmetric clock aging in the round-trip experiment as a "fallback into absolutist way of thinking", claiming that special relativity requires that any difference between the clocks vanishes when their relative velocity is zero again, even though he added that any treatment of the clock paradox in special relativity is unrealistic anyway, since the theory only concerns uniform motions and therefore cannot handle velocity changes, so one has to modify the theory. Einstein responded by letter in which he praised Petzoldt's philosophical take on relativity, yet he rejected Petzoldt's conclusions concerning the clock paradox by showing that any finite acceleration at turnaround during the round-trip can only influence the clock in a finite way and therefore can be neglected by minimizing the time of acceleration with respect to the time of uniform translation, so it "must be concluded" that the clock traveling on a polygonal path is retarded at reunion.
May 1914:<ref name=rowe group=S /> During a conversation with [[w:Ernst Gehrcke]] who claimed that the clock paradox contradicts the relativity principle, Einstein replied that clock B is retarded because it was accelerating in contrast to clock A; while those accelerations are irrelevant for the amount of the time difference, their presence nevertheless cause B to fall behind ("accelerated motions are absolute in the theory of relativity").
1916:<ref name=einstein16 /> In a lecture of which only an abstract was published, Einstein spoke about the "clock paradox of special relativity from the standpoint of general relativity."
September 1918:<ref name=einadl /> In a letter to Einstein, [[w:Friedrich Adler (politician)|Friedrich Adler]] (while in prison for the [[w:Assassination of Karl von Stürgkh]]) claimed that the clock paradox which he described on a circular round-trip contradicts the special relativity principle, and also referred to the similar opinions of Berg and Petzoldt. Einstein responded by letter and explained that there is no contradiction as one of them accelerates; he then showed that general relativity makes both inertial frame K and accelerated frame K' equally justified, explaining the time difference in K' by combining the influence of velocity and gravitational potential, concluding that "Berg and Petzoldt were wrong".
November 1918:<ref name=einstein18 /> In a fictitious dialogue between a relativity critic and a relativity apologist written by Einstein, the "critic" said that special relativity must predict differential clock aging in round-trip experiments, which was confirmed by the "relativist" who regretfully noted that even some pro-relativity authors tried to "circumvent this unavoidable result". Yet the critic claimed that this leads to a contradiction: From the viewpoint of K, clock U1 is at rest while the clock U2 was in motion and therefore returns being retarded with respect to U1, but from the viewpoint of K', clock U2 is at rest while clock U1 was in motion and therefore returns being retarded with respect to U2, which was rebutted by the relativist by pointing out the acceleration of U2. Then the critic claimed that this problem "rises again from the dead" in general relativity which allows to symmetrically treat both K and K', which was rebutted by the relativist using the equivalence principle: In K', the rate increase of U1 during turnaround period 3) is "the double" of its velocity time dilation in the inertial periods 2) and 4).
December 1918:<ref name=einstein18b /> In a letter to Einstein, [[w:Max Jakob]] doubted the result from Einstein's dialogue, according to which the advance of U1 in period 3) is the double of its retardation during periods 2) and 4). Einstein responded by letter, in which he used the gravitational time dilation factor <math>1+\Phi/c^{2}</math> in K' in order to show that U1 at distance <math>l</math> is advancing by <math>\Phi/c^{2}=2vl/c^{2}</math> in period 3), which is indeed the double of approximated delay <math>vl/c^{2}</math> caused by velocity time dilation during periods 2) and 4).
1920:<ref name=einstein20 /> In conversations with [[w:Alexander Moszkowski]] between 1919 and 1920, Einstein argued that differential aging of the twins is rather a paradox of feeling, not a paradox of thought, because the latter would only arise if there were no reason for the asymmetric aging. The reason in special relativity lies in the fact that one of them suffered accelerations, while a deeper understanding of that question is obtained by using general relativity. Einstein argued that our "common sense" is located in the realm of feeling and analogy drawn from our ordinary experience; since there is no analogy to the example of the twins in our experience, it might appear paradoxical to the common sense, while it appears logical and necessary in light of intensified abstraction of the trained scientific mind.
August 1920:<ref name=rowe group=S /> At an anti-relativity event organized by the right-wing agitator [[w:Paul Weyland]] during which [[w:antisemitic]] leaflets were distributed and [[w:swastika]]s offered at the entrance, a lecture was given by Gehrcke re-iterating his criticism of the twin paradox, claiming that the stationary first organism is old or even dead at reunion while the second organism was in motion and therefore stayed young, but from the standpoint of the second organism he himself is old or even dead while the first organism was in motion and stayed young, thus relativity is either contradictory or it leads to different realities and physical [[w:solipsism]]. Einstein who was present at that event, directly responded in a newspaper article;<ref name=einst20 /> after suspecting antisemitic motives of his critics, he specifically addressed Gehrcke's objections regarding the "well known example of the clocks (or twins)", remarking that the charge of solipsism will be "greeted by the experts as a joke", and characterized the claim that relativity requires mutual retardation of two co-located clocks as a "deliberate attempt to misinform the lay public".
1922:<ref name=morand /><ref name=nord /> [[w:Paul Painlevé]], Einstein and Langevin discussed the clock paradox at a meeting in Paris. Painlevé imagined a clock on a train that performs a round-trip with constant speed and returns being retarded with respect to the station clock, yet he claimed that the relativity principle also allows to say that the station clock performed the round-trip and returned being retarded with respect to the train clock, in contradiction to the previous result. Einstein replied that the relativity principle cannot be applied since the train is not in a Galilean system (i.e. inertial frame) any longer during the period of velocity change at turnaround, i.e. the ensemble of two systems having velocities in opposite direction is not an inertial frame; there is no reciprocity between a frame that changes direction and one that doesn't. Langevin consequently gave a detailed analysis in terms of the Lorentz transformation.
1954:<ref name=einstein54 /> In a letter, Einstein explained the "well known clock paradoxon" using two clocks <math>B_{1}</math> and <math>B_{2}</math>; clock <math>B_{2}</math> has to reverse its speed in order to come back, thus it was initially at rest in inertial frame <math>S_{2}</math> and then at rest in <math>S_{2}^{+}</math>, whereas <math>B_{1}</math> constantly remains at rest in <math>S_{1}</math>, which explains the asymmetry between them.

== Feedback on theory application ==
Hi! I really like how you've explained autonomy, competence and relatedness and linked them to social media. One thing that could be interesting is showing a bit more of how each need can be both supported and frustrated by social media. For example, social media could support relatedness by helping someone feel connected to others, but things like exclusion or negative social comparison could have the opposite effect. I think comparing both sides could make the link between BPNT and social media use even clearer.
I also thought your opening scenario could be good to come back to later in the chapter. You could link responding to the friend with relatedness, and then the shift into mindless scrolling with a loss of autonomy. I think that would help connect the scenario back to the theory really well.
Great work so far! It's looking really good [[User:U3260591|U3260591]] ([[User talk:U3260591|discuss]] • [[Special:Contributions/U3260591|contribs]]) 00:54, 24 September 2026 (UTC)

'''Understanding love in pop culture'''
''Do you ever wonder how the media portrays love-driven behaviours?''
Filmmakers and game developers intentionally create love-driven character stories as it floods our brain with oxytocin (the "bonding and empathy" hormone). In turn, this hormone enhances our viewing experience, making films and video games much more memorable (Zak, 2015).
In the 2026 psychological horror film the [https://en.wikipedia.org/wiki/Backrooms_(film) Backrooms] {{ic|Use an internal link as shown in Tutorial 2}}, the deuteragonist, Mary, investigates the disappearance of her patient, Clark. She visits his workplace, ''Cap'n Clark's Ottoman Empire'', and unknowingly stumbles across the backrooms of the establishment. Mary's decision to search for Clark requires considerable risk and effort. Her behaviour raises the question of why a person might pursue another person's wellbeing, even when doing so conflicts with their own safety. A more positive example of giving and receiving love is portrayed in the popular 2013 video game [https://en.wikipedia.org/wiki/The_Last_of_Us The Last of Us]. The game centres around a hardened smuggler named Joel who must escort a teenage girl named Ellie across a post-apocalyptic United States. As they spend more time together, their relationship develops into a close emotional bond resembling that of a parent and child.

#* '''Outline the aim of the chapter'''; (i.e. this chapter develops the readers{{g}} understanding of the desire to give and receive love, and how motivation plays an important role in influencing said behaviours. This chapter will draw on a breath of psychological research, including key concepts and terms, and draw upon different psychological theories related to understanding love. This is to provide the reader a comprehensive but applicable direction for knowledge.
'''''DRAFT OVERVIEW:'''''
Love is a complex interpersonal experience that can influence how people think, feel, and behave. In psychology, motivation refers to the processes that give behaviour direction, intensity, and persistence. The desire to love and be loved can therefore be understood as a source of motivation. Motivation can influence people to initiate and invest in meaningful relationships. Love and belonging involve the desire for affection and acceptance, while interpersonal connection refers to the emotional and social bonds people develop with others.
Several psychological theories provide different perspectives for understanding this relationship between love and motivation. Maslow's hierarchy of needs conceptualises love and belonging as fundamental human needs, while basic psychological needs theory identifies relatedness, or feeling connected to and cared for by others, as a fundamental psychological need. Attachment theory provides another framework for understanding how close emotional bonds can influence behaviour. Particularly, caregiving and responses to separation or threat.
Recommended length: 180-330 words.

{{RoundBoxTop|theme=12}}'''Focus questions'''
{{ic|Use bullet points as shown in Tutorial 2}}
1. Why is the need to love and be loved considered an important source of human motivation?
2. How do psychological theories explain the motivation to form and maintain meaningful relationships?
3. How does the desire to give and receive love influence behaviours such as affiliation, caregiving, and prosocial behaviour?
4. When can the motivation to obtain love and belonging conflict with other psychological needs or become maladaptive?

====== 1.1 The Need to Belong ======
[[File:Human–canine friendship - girl hugging her dog tightly at golden hour in Laos.jpg|thumb|'''Figure 2'''. A companionship that goes beyond.]]
Love and interpersonal relationships can influence motivation by directing people towards social connection. In other words, forming and maintaining relationships. Humans do not simply interact with others because social interaction is available. Baumeister and Leary (1995)'s [https://www.researchgate.net/profile/Mark-Leary-2/publication/15420847_The_Need_to_Belong_Desire_for_Interpersonal_Attachments_as_a_Fundamental_Human_Motivation/links/5b647053aca272e3b6af9211/The-Need-to-Belong-Desire-for-Interpersonal-Attachments-as-a-Fundamental-Human-Motivation.pdf Theory of Belonging] reviewed evidence supporting the belongingness hypothesis and concluded that people have a pervasive desire to form social attachments.
People readily develop relationships with others, including under adverse circumstances, and tend to resist the loss or dissolution of existing social bonds even when maintaining them provides no obvious practical benefit. This suggests that interpersonal relationships can function as motivation goals in their own right rather than simply serving other purposes. The importance of belonging can be seen in the psychological consequences associated with social connection and disconnection. Rather than being simply a preference for social interaction, belongingness can influence emotional and cognitive processes. This explains why people may invest considerable time and effort into developing and maintaining relationships. The desire for connection can also become particularly influential when an individual's relationship is perceived as a threat or when dependence on another person becomes excessive. For example, Guan et al., (2015) examined 80 couples longitudinally and found that love addiction was positively associated with emotional dependence and negatively associated with attachment avoidance. Their findings suggest that the motivation to maintain close romantic relationships can interact with attachment patterns and interpersonal dependence.
====== 1.2 Love, Connection, And Relatedness ======
Belongingness refers to the human emotion to be accepted as a member of a group. Whether family, friends, co-workers, a religion, or something else. People have an inherent desire to belong.
[[File:20110702-31-Ilana_tim_and_becca_hug_(5972579616).jpg|thumb|225x225px|'''Figure 3'''. Friends hugging.]]
Love can therefore be one way through which the broader need for interpersonal connection is experienced and expressed. Qadir et al., (2026) explored occupational therapists' experiences of belongingness within interprofessional clinical environments and found colleagues and patients contributed to participants' sense of belonging. Conversely, organisational barriers, discrimination and difficulties establishing a professional identity could undermine this sense of connection. The study also illustrates how belongingness and motivation can reinforce one another. Participants identified achievement, professional development and appreciation from others as important sources of motivation, while supportive and welcoming interactions contributed to their sense of belonging. This suggests that interpersonal environments can both motivate individuals to participate and develop the social acceptance that contributes to belongingness.

''Imagine you could only have one person on your phone's lock screen for the next year. Who would you choose, and why them?''
A lock screen is a practical feature of a phone, yet the image we choose to display can carry considerable emotional meaning. People may choose photographs of partners, family members, friends, or other significant individuals, turning an everyday object into a reminder of an important relationship. Conroy and Fraley (2026) investigated whether photographs of romantic partners could function as everyday attachment-related cues. Their findings suggested that lock screens are embedded with psychological processes involved in close relationships. Simply put, people like having photos of their partners.{{RoundBoxBottom}}
== 2. Theories Explaining Love ==
{{expand}}
====== 2.1 Maslow's Hierarchy of Needs ======
Maslow (1943) proposed that human motivation is influenced by a hierarchy of needs. Beginning with physiological needs and safety, then love and belonging, and finally esteem and self-actualisation. Within this framework, love and belonging involve the desire for affection and acceptance. When these needs are insufficiently satisfied, individuals may become motivated to seek relationships and social connection.
====== 2.2 Self-Determination Theory ======
People are centrally concerned with motivation, how to move themselves or others to act (Ryan & Deci, 2000).

{{title|Exercise gamification motivation:<br>How can gamification affect exercise motivation and behaviour?}}
__TOC__
==Overview==
{{RoundBoxTop|theme=4}}
[[File:WORKOUT.jpg|thumb|Man earning points for exercising (figure 1)]]
'''Case study: Meet Alex'''
Alex has recently started using a fitness app to become more physically active. The app awards points for completing workouts, gives badges for reaching milestones, displays weekly challenges, and allows users to compare their progress with friends (see figure 1). At first, Alex exercises mainly to improve their health, but soon becomes increasingly motivated by earning enough points to reach the next level. When Alex moves up the leaderboard, they feel a sense of achievement and become more motivated to exercise again. However, after falling behind other users, Alex begins to lose interest and considers stopping.
Alex's experience raises an important question: why can the same gamification features that motivate exercise for some people have different effects on motivation and behaviour for others?
{{RoundBoxBottom}}
Regular physical activity provides important physical and psychological benefits, yet maintaining exercise behaviour can be difficult. Digital fitness technologies increasingly use gamification, such as points, rewards, challenges, feedback and social comparison, to encourage people to become more active. Gamification may make exercise more engaging and provide users with goals and feedback, but its effects on motivation and behaviour are not necessarily straightforward.
Psychological science can help explain why gamification may influence exercise motivation and whether increased motivation translates into sustained exercise behaviour. Understanding motivation theories can also help identify when gamification is likely to support engagement and when it may instead reduce motivation or discourage participation.

{{RoundBoxBottom}}
== Understanding exercise gamification ==
Digital technologies have changed how people monitor and engage in physical activity. Smartphones, fitness applications, and wearable devices can track behaviours such as daily steps, workout frequency, and exercise intensity while providing immediate feedback on progress. Additionally, these technologies also include features traditionally associated with games to make physical activity more engaging. This approach, known as gamification, is commonly used to encourage participation and maintain motivation for exercise.
=== What is exercise gamification? ===
Gamification refers to using game-design elements in non-game contexts. In exercise settings, this means adding game-like features to an activity that isn't necessarily a game. For example, a person may earn points for completing a workout, maintain a streak to reach a daily step goal, or compete against friends on a leaderboard. This differs from an exergame, where physical activity forms part of the gaming experience. Instead, gamification adds selected game elements to an existing activity to influence motivation and behaviour (Krath et al., 2021).
=== Common gamification features ===
Exercise gamification can take many forms, including points, badges, rewards, challenges, progress tracking, feedback and leaderboards. These features turn physical activity into measurable goals and achievements, allowing users to track performance and receive feedback on their progress. For example, Shameli et al. (2017) examined how app-based walking challenges could encourage users to increase their daily physical activity, demonstrating how a relatively simple game element can be applied to an everyday behaviour such as walking.
A systematic review of 50 gamified physical activity interventions found that goal-setting was the most frequently used game element, appearing in 60% of studies, followed by progress bars (52%), rewards (50%), points (44%) and feedback (42%). Competition, collaboration, leaderboards, challenges and badges were also identified, showing that gamification can involve considerably more than simply earning points or rewards (Xu et al., 2022).
Importantly, different game elements may not be equally effective. A recent systematic review and meta-analysis found that the effects of gamified physical activity interventions among children and adolescents varied by factors including the game elements used, theoretical approach, and intervention duration (Wang et al., 2025). Gamification should therefore not be considered a single behaviour-change strategy with a consistent effect. Instead, different features may influence exercise motivation and behaviour through different psychological processes. Understanding these processes requires examining the psychological theories that explain why gamification can motivate exercise in the first place.
== Psychological mechanisms of gamification ==
Gamification can influence exercise motivation through several psychological processes, not just by making physical activity more entertaining. Understanding these processes helps explain why the same game feature may motivate one person while pressuring or discouraging another.
=== Self-determination theory ===
Self-determination theory (SDT) provides a useful framework for understanding why the same exercise goal can feel motivating in one situation but pressuring in another. SDT proposes that motivation is influenced by the satisfaction of three basic psychological needs: autonomy (the feeling of having choice and control over one's actions), competence (the feeling of being capable and effective) and relatedness (the feeling of connection and belonging with others) (Ryan & Deci, 2020). Environments that support these needs are more likely to encourage higher-quality motivation, whereas environments that frustrate them may undermine motivation.
Importantly, SDT distinguishes between different qualities of motivation rather than simply asking how motivated someone is. Autonomous motivation occurs when a behaviour is enjoyable or personally valued (Yaban & Gaschler, 2025). For example, someone may exercise because running is enjoyable or because improving their health matters to them. In contrast, controlled motivation involves internal or external pressure, such as exercising to avoid guilt, gain approval or obtain a reward (Claes et al., 2026). At the far end of the spectrum, amotivation describes a lack of intention or meaningful motivation to act (Hardcastle et al., 2015). These distinctions matter because two people can complete the same workout for very different reasons.
Research supports the relevance of these distinctions to exercise behaviour. A systematic review of 66 studies found that autonomous forms of motivation were consistently associated with exercise participation, with identified regulation appearing particularly relevant to initial exercise adoption and intrinsic motivation showing stronger links with long-term adherence (Teixeira et al., 2012). Similarly, a meta-analysis involving 15,984 children and adolescents found moderate positive associations between autonomous motivation and physical activity, whereas controlled forms of motivation showed weak negative associations (Owen et al., 2014). More recent evaluations of SDT research suggest that theory-informed interventions can improve physical activity. However, effects are generally small to moderate and appear to operate mainly through autonomous motivation and competence need satisfaction (Ntoumanis & Moller, 2025).
SDT therefore offers more than an explanation of whether gamification can make exercise motivating. It raises a more important question: what type of motivation gamification creates. A progress indicator that helps someone recognise improvement may support competence, whereas a reward that makes exercise feel obligatory could create external pressure. Understanding whether game features support or frustrate psychological needs may therefore help explain why gamification can strengthen motivation in some circumstances but undermine it in others.
=== How gamification can support motivation ===
Gamification supports exercise motivation when game elements help satisfy the psychological needs described by self-determination theory. Rather than motivation arising simply because an activity includes points or rewards, it matters more to understand how participants experience these features. Gamification can provide clear goals, immediate feedback, visible progression and opportunities for social interaction, all of which can contribute to motivational experiences (Krath et al., 2021).
Competence may be particularly relevant to exercise gamification. Features such as progress bars, performance feedback, levels and achievable challenges allow users to see evidence of improvement. For example, watching a weekly step goal gradually fill provides immediate feedback on progress toward an achievable target. Gamification can also adjust task difficulty to a user's abilities, potentially keeping challenges achievable while still requiring effort (Krath et al., 2021). These features may help users feel increasingly capable rather than viewing exercise as an activity in which they are unsuccessful.
Gamification may also support autonomy when users are given meaningful choices over their goals and how they pursue them. Personalised goals, optional challenges and different progression paths can provide greater control than systems that impose the same targets on every user. Similarly, relatedness may be supported through social features that allow users to cooperate, share progress or work towards common goals. Social interaction may therefore provide encouragement and a sense of connection alongside the exercise itself.
However, the presence of these features does not necessarily mean that psychological needs will be satisfied. Reviews of health gamification have noted that interventions often combine multiple game elements, making it difficult to determine which specific features produce motivational effects (Johnson et al., 2016). This distinction matters because a leaderboard that builds connection and friendly competition for one person could create pressure or discouragement for another. Therefore, the motivational value of gamification may depend less on whether game elements are present and more on how those elements are designed and experienced.
Figure 2 illustrates how game elements may influence exercise behaviour through their effects on psychological experiences and motivation.

<quiz display=simple>
Which feature is most likely to support autonomous exercise motivation?
|type="()"}
- Users lose points whenever they miss a workout.
|| Punishing missed workouts may create pressure to exercise, making motivation feel more controlled rather than self-directed.
+ Users choose their own exercise goals and receive feedback about their progress.
|| Providing choice can support autonomy, while progress feedback can support competence. Both are important psychological needs within self-determination theory.
- Users are publicly ranked against other users.
|| Public rankings emphasise comparison and external performance. For some users, this may shift attention towards external outcomes rather than autonomous reasons for exercising.

=== When gamification can undermine motivation ===
<div style="border: 2px solid #4a7ebb; background-color: #f2f7fc; padding: 15px; margin: 20px 0; border-radius: 8px;">
'''Case study: Same app, different motivation'''
Jordan and Sam use the same fitness app, which awards points, tracks exercise streaks, and ranks users on a leaderboard. Jordan enjoys seeing their progress and feels encouraged to exercise regularly. Sam becomes anxious about losing their streak and discouraged when they fall behind other users.
'''Reflection question'''
Using self-determination theory, how could the different responses of Jordan and Sam be explained?
''Think about how the app may affect each person's autonomy, competence, and reasons for exercising.''
</div>
Gamification does not always support autonomous exercise motivation. From an SDT perspective, rewards, competition and performance targets may become controlling when users feel pressured to exercise for an external outcome rather than because the activity is enjoyable or personally meaningful (Ryan & Deci, 2020). For example, maintaining an exercise streak may initially encourage consistency, but the desire to avoid losing it could shift motivation toward pressure and obligation.
Competition can also produce different experiences across users. Leaderboards may provide enjoyable social comparison for some people but may discourage users who repeatedly see themselves performing below others. Research on gamification similarly suggests that individual responses to game elements can vary, meaning that features intended to motivate do not necessarily benefit every user in the same way (Krath et al., 2021).
This distinction highlights a potential limitation of exercise gamification. Increasing engagement with a gamified system is not necessarily the same as developing sustainable motivation for exercise. A person may exercise to earn points, maintain a streak or outperform others without developing a personally meaningful reason to remain active. Whether this motivation persists when the game element disappears therefore becomes an important question.
== Gamification and exercise behaviour ==
Increased motivation does not necessarily mean that a person will maintain exercise behaviour. Research must therefore distinguish between motivation, engagement with gamified features and actual changes in physical activity.
=== Effects on physical activity ===
Overall, research suggests that gamification can produce measurable increases in physical activity. A meta-analysis of gamified smartphone applications found a small-to-moderate positive effect on physical activity compared with non-gamified conditions, indicating that game elements can influence behaviour rather than simply increasing interest in an application (Yang et al., 2022). However, substantial variation between studies suggests that gamification does not produce consistent effects across all interventions. Differences in game elements, intervention design, and participant characteristics may partly explain these mixed outcomes.
=== Short-term motivation and long-term adherence ===
Evidence that gamification increases physical activity in the short term does not necessarily mean these changes will be maintained. Mazeas et al. (2022) found that gamified interventions produced a small-to-moderate positive effect on physical activity immediately after the intervention (''g'' = 0.42). However, at a longer-term follow-up, at approximately 14 weeks, the effect was considerably smaller (''g'' = 0.15), although it remained statistically significant.
This suggests that gamification may be more effective at encouraging initial engagement than producing substantial long-term behaviour change.Importantly, continued app use or pursuit of rewards should not automatically be interpreted as sustained exercise motivation. Long-term effectiveness depends not only on whether gamification encourages activity while game elements are present, but whether exercise behaviour persists over time.
=== Do different gamification features work differently? ===
The effectiveness of gamification may depend on which game elements are used and how they are designed. A systematic review and meta-analysis of gamified smartphone applications found small-to-moderate improvements in physical activity, but considerable variation between interventions (Yang et al., 2022). This variation may partly reflect differences in features such as rewards, challenges, feedback and social comparison, as well as how these elements are combined. Research also suggests that individual game elements can create different psychological experiences rather than producing a consistent motivational effect (Krath et al., 2021). Therefore, successful gamification may depend less on including as many game elements as possible and more on selecting features that support the intended motivational and behavioural outcomes.
== Designing effective and sustainable exercise gamification ==
Understanding why gamification influences motivation can help inform how exercise technologies are designed. Effective gamification should apply psychological and behaviour-change principles rather than simply adding game elements in the hope of increasing engagement.
=== Supporting meaningful motivation ===
Effective gamification should support meaningful reasons for exercising rather than focusing only on external rewards. Features such as personalised goals, progress feedback, and achievable challenges may support autonomy and competence by giving users greater control and making improvement visible (Krath et al., 2021). From an SDT perspective, this may encourage more autonomous motivation than systems that pressure users towards predetermined targets. Gamification design should therefore consider the psychological experience created by game elements, not simply the number of features included.
=== Balancing rewards, competition and pressure ===
Rewards and competitive features require careful design because they may motivate users in different ways. Leaderboards and challenges can provide achievement and social comparison, but they may also create pressure or discourage users who consistently perform below others (Krath et al., 2021). Similarly, rewards may encourage participation without necessarily developing autonomous motivation. Exercise gamification should therefore avoid making points, streaks or rankings the primary reason for being active and instead use these features to complement personally meaningful exercise goals.
=== Designing for sustained exercise ===
Sustainable gamification should ultimately encourage continued exercise rather than dependence on the gamified system. Evidence that gamification effects become smaller at longer-term follow-up suggests that initial increases in activity do not always translate into lasting behaviour change (Mazeas et al., 2022). Future studies should also investigate which combinations and implementations of game elements are most effective, as existing studies show mixed results and considerable variation in their design (Xu et al., 2022). Gamification should therefore support meaningful goals, feedback, and psychological needs while helping exercise become a personally valued and sustainable behaviour.
<div style="border: 2px solid #4f8a5b; background-color: #eef8f0; padding: 15px; margin: 20px 0; border-radius: 8px;">
'''Key principles for sustainable exercise gamification'''
✓ '''Support meaningful goals''' — Connect gamification with personally valued reasons for exercising.
✓ '''Make progress visible''' — Provide useful feedback that supports feelings of competence.
✓ '''Provide meaningful choice''' — Allow personalisation rather than imposing identical goals on every user.
✓ '''Use rewards and competition carefully''' — Avoid creating excessive pressure or dependence on external rewards.
✓ '''Think beyond short-term engagement''' — Design gamification to support sustained exercise behaviour, not simply continued app use.
</div>
==Conclusion==
Gamification can influence exercise motivation and behaviour by using features such as goals, feedback, rewards, progress tracking and social interaction to make physical activity more engaging. However, simply adding game elements does not guarantee meaningful or lasting behaviour change. Self-determination theory helps explain this difference: gamification may strengthen motivation when it supports autonomy, competence, and relatedness, but may create pressure or controlled motivation when these psychological needs are frustrated.
Research suggests that gamification can produce small-to-moderate increases in physical activity, although effects vary across interventions and tend to weaken over time. This highlights an important distinction between increasing short-term engagement and supporting long-term exercise adherence. Different users may experience the same game elements differently, so effective design should consider the psychological experience created rather than simply the number of features included.
Sustainable exercise gamification should therefore support meaningful motivation through personalised goals, achievable challenges, useful progress feedback, meaningful choice and opportunities for social connection. Ultimately, gamification is most useful when game elements support continued physical activity rather than becoming the primary reason for exercising.

__TOC__
== Overview ==
{| class="wikitable"
|'''Case study: part 1'''
'''Imagine this....'''[[File:School children happily playing in playground.jpg|thumb|'''Figure 1.''' ''Children engaged in outdoor play.'']]A child arrives at playground and joins a group of children who are already playing. The children are making their own game and deciding the rules as they play. At first, child enjoys choosing where and what to play and moving between the different activities. During the game, another child changes the rules of the game and argument breaks out. The child becomes frustrated and avoids the activity. After watching for short time, the child returns, suggests for new idea to continue game and re-joins the group. How might experiences like this during outdoor play influence children's emotional well-being? Emotional regulation theory provides one way of understanding on how children may respond to emotional situations during play (see figure 1) (Gross, 2015).
|}
Outdoor play can involve more than physical movements. It is more than simply being outside and engage in the activities across playgrounds, gardens, streets and natural spaces. Outdoor play involves exploration, social interaction, choice and challenge and engagement with surrounding environment (Dodd et al.,2026; Pereira et al.,2024). These experiences may create emotional situations in which children need to respond to frustration, disagreement, uncertainty or excitement. Gross (2015) [[emotional regulation]] theory provides a [[psychological]] explanation for how children may recognise and respond to these emotional situations. Outdoor play experiences are also shaped by the environment where play takes place. Experiences are shaped by the different opportunities provided by different physical and social environments, which means the same outdoor space may not provide the same experience for every child (Morgenthaler et al.,2024).This chapter examines how [[Emotional regulation|emotional,]] [[Cognitive psychology|cognitive]], social and environmental processes may help explain the relationship between outdoor play and children's emotional well-being.

== '''Understanding outdoor play and children's emotional well-being''' ==
[[File:Water-outdoor-people-girl-play-boy-938233.jpg|thumb|'''Figure 2'''. ''Visualise outdoor play as providing children with opportunities to explore, make choices, interact with others and respond to changing situations through activities such as water play.''|347x347px]]
Outdoor play and children's emotional well-being are not measured as single and consistent concepts across recent research. Outdoor play may be examined as voluntary and intrinsically motivated activity, self directed play, parent reported outdoor play, or device-measured outdoor play activity. It should also be distinguished from outdoor moderate to vigorous physical activity because these measures do not represent the same behaviour (Davenport et al., 2025). Children's emotional well-being is also examined through different outcomes, that includes [[emotional regulation]], social-emotional competence, positive and negative affect, and internalising or externalising symptoms. These differences are significant because outdoor play and emotional well-being are not measured as single, consistent constructs across research.
=== Outdoor play ===
Outdoor play is voluntary and and intrinsically motivated activity that occurs in outdoor environments like gardens, playgrounds, parks and natural spaces (Dodd et al., 2026). Free play can be also self-directed, which means children to freely interact with the environment and have autonomy to make choices about their activities (Biino et al., 2025). Outdoor play should not be treated as same as outdoor physical activity. Davenport et al., (2025) examined outdoor play separately from outdoor moderate- to- vigorous physical activity (MVPA). This distinction is significant because research on children's outdoor play is not necessarily measuring the same behaviour as research on the intensity of physical activity.
=== Children's emotional well-being ===
Children's emotional well-being is not represented by single common outcome across recent outdoor play research. Emotional dysregulation has been examined in relation to the amount and timing of outdoor play (Lee et al., 2025), while social-emotional competence includes difficulties and [[Prosocial behavior/Keywords/Definitions|prosocial behaviour]] (Ferguson et al., 2025). Other studies have examined positive and negative affect following recess (Poulos et al., 2026) and trajectories of internalising and externalising symptoms across childhood (Dodd et al., 2026). These outcomes represent different aspects and timeframes of emotional functioning, so they should not be treated as equivalent when findings are compared.

As shown in Table 1, the studies do not measure the same aspect or time frame of children's emotional functioning. Affect immediately following recess should not be treated as equivalent to emotional dysregulation measured over time or trajectories of internalising and externalising symptoms across childhood. This difference need to be considered when examining whether outdoor play is associated with children's emotional well-being.
'''Case study: part 2'''
''What is being measured?''
{| class="wikitable"
| valign="top" |[[File:Children marbles.jpg|thumb|177x177px|'''Figure 3'''. ''Children may experience different emotional responses during social outdoor play'']]The child in the case study part 1 becomes frustrated when the rules of the game change. This immediate emotional response is different from a longer-term pattern of emotional dysregulation or internalising symptoms. When research findings are compared, it is important to consider which aspect of emotional well-being is measured.

== '''How does outdoor play influence children's emotional well-being?''' ==
* Lee et al. (2025) examined working memory as possible process between outdoor play and emotional regulation. Dodd et al.(2026) discussed cognitive, social and emotional skills development, social interaction, physical activity, connection with the nature, adventurous play as possible measures for association between outdoor play and mental health symptoms.
* Lee et al. (2025) examined 325 preschool children and used meditation analysis to test whether the timing and amount of outdoor play were related to emotional dysregulation and working memory.
* Dodd et al. (2026) found that more frequent outdoor play during the preschool years predicted healthier mental health trajectories into middle childhood. The study used nationally representative longitudinal cohort and suggest possible pathways that includes cognitive, social and emotional skills development, exposure and relation with the nature, physical activity, social interaction and adventurous play.
* These pathways were proposed by Dodd et al.(2025) but not directly tested as mechanisms. The findings of the study do not shows outdoor play causes better emotional well-being. Many of the existing outdoor play research remains observational (De Lannoy et al., 2023).
=== '''Emotion regulation''' ===
* [[w:Emotional_self-regulation|Emotional self-regulation]] regulation provides an understanding of how children manage emotional situations. Gross (2015) describes emotional regulation as a process involving identification, selection and implementation. Identification concerns deciding whether to regulate an emotion, selection concerns selecting regulation strategy and implementation concerns applying chosen response into practice.
* Gross (2015) describes {{ic|Use past tense here}} various forms of emotion regulation like situation selection, situation modification, attention deployment cognitive change and response modulation. During outdoor play a child may experience frustration, conflict, disagreement, uncertainty or changes to their activity. These process provide a psychological framework for understanding how people respond to emotional situations. This model can be applied to these outdoor play situations to consider how children might recognise emotional response, decide how to manage the situation, and act on that decision.
* However, this is an application of Gross (2015) theoretical framework to outdoor play. This study did not examine whether outdoor play influence to children's emotion regulation.
=== '''Working memory and cognitive process''' ===
* Lee et al. (2025) examined [[w:Working_memory|working memory]] as a mediator between outdoor play and emotional dysregulation among 325 preschool children. Outdoor play was examined across three part of the day: wake-up to noon, noon to 6 pm and 6 pm to bedtime.
* The timing of outdoor play was important. More outdoor play between noon and 6 pm was related to lower emotional dysregulation. In contrast, more outdoor play before noon and after 6 pm was related to higher emotional dysregulation (Lee et al. 2025).
* Lee et al (2025) found that more outdoor play from noon to 6 pm was associated with better working memory (b=1.61, p<.05) and better working memory was associated with lower emotional dysregulation (b= -0.08, p< .01). This relation between noon to 6pm outdoor play and emotional dysregulation as no longer statistically significant when working memory was included in the analysis. As a result it is reported as full mediation.
* The findings suggest that working memory can be one cognitive functioning process involved in the association between outdoor play and emotional regulation. However, statistical mediation in an observational study which does not prove that outdoor play caused better working memory or emotional regulation. Lee et al. (2025) called for further research examining both immediate and longer-term effects of outdoor play on working memory and emotion regulation.
{{ic|Add an APA style table caption}}
{| class="wikitable"
|Key points
* Lee et al. (2025) found that associations between outdoor play and emotional dysregulation differed according to time of day.
* Working memory statistically mediated the association between afternoon outdoor play and lower emotional dysregulation in Lee et al. (2025).
* Dodd et al. (2026) found that more frequent preschool outdoor play predicted lower odds of non-normative internalising and externalising symptom trajectories.
|}
== '''Social and environmental influences on outdoor play''' ==
* Outdoor play opportunities are shaped by more than the physical being outdoor space. Beekhuizen et al. (2025) interviewed 40 children aged 6 to 12, with and without disabilities about facilitators and barriers to inclusive outdoor play. The findings were identified personal factor, interacting factors and environmental factors.
* Personal factors included experiencing [[w:Autonomy|autonomy]], and children's feelings of physical and social limitations. Interacting factors included making contact, growing up together, and adopting the ways of playing. Environmental factors included parents, outdoor play environments, communities, and time constrains (Beekhuizen et al., 2025).
* Opportunities for outdoor play was not experienced in the same way by all children. Beekhuizen et al. (2025) found that children with disabilities experienced more barriers than children with no disability. The challenges were related to making contact with other children, adopting play and the physical play environment.
* Ferguson et al. (2025) examined the association between outdoor play and children's social-emotional competence. In a cross sectional analysis of 2568 children, aged 7.1 to 12.6 years from multi-ethnic urban cohort found that outdoor play was associated with better social-emotional competence. However, the association was differed across ethnicity, and weekday or weekend outdoor play.
* Ferguson et al. (2025) also examined area deprivation. The relation between outdoor play and social-emotional competence appeared stronger in less deprived area, although the statistical evidence for the differences by deprivation was significantly weak.
=== '''Social relationship and inclusion''' ===
* Beekhuizen et al. (2025) identified making contact and growing up together as interacting factors in inclusive outdoor play. Some children described familiarity with other children as an easy way to approach, communication and play together. Making contact could also be a barrier when children approaching to another unfamiliar children or joining in play who were already playing.
* Children also described the need to adopt games so that children with different abilities could participate. School and communities were identified settings where children with and without disabilities could become familiar with each other (Beekhuizen et al., 2025).
* In the recent observational research by Beekhuizen et al. (2026) observed outdoor play among children with and without disability. The researchers found that getting to know each other, making contact and interaction while playing together as process of inclusive outdoor play. These observational findings showed that familiarity and making contact determine social and inclusive play because children chose to play with children they already knew.
* Ferguson et al. (2025) also found that the association between outdoor play and social emotional competence was not the same across all ethnic and deprivation groups. In the cross sectional analysis of 2568 children aged 7.1 to 12.6 years from multi ethnic urban cohort, outdoor play was associated with better social-emotional competence. However, associations varies across same ethnic groups and according to weekday or weekend outdoor play.
=== '''Autonomy, parents and time''' ===
* Experiencing autonomy was identified as a personal factor in inclusive outdoor play. Children having some independence during outdoor play could promote their sense of independence over what they do and who they play with (Beekhuizen et al., 2025).
* Experiencing autonomy also included opportunities to play without direct involvement of parents. Some children with disabilities described wanting to play outside independently, although parental support could make outdoor play possible (Beekhuizen et al., 2025)
* Parents were identified as an environmental factors. Beekhuizen et al. (2025) found that parental involvement could support children's participation in outdoor play, specially when child needed help to access or participate in outdoor play.
* Time constraints were considered as another environmental factor. Some children with disabilities were described as having limited outdoor play time due to parents work schedule, after-school arrangements or longer travel distance between home and school (Beekhuizen et al., 2025)
=== '''Outdoor environments and accessibility''' ===
* The outdoor play environment was identified as an environmental factor that could could support or restrict inclusive outdoor play. Children described both physical and social aspects of outdoor play environments. For example, children discussed the importance of physical and social safety, including traffic near playgrounds and disputes among children. Accessibility was particularly relevant to children with disabilities because opportunities for inclusive outdoor play could be affected by play environments and physical abilities (Beekhuizen et al., 2025).
* Pereira et al. (2024) provided evidence about the physical features of outdoor play spaces. Their systematic review included 51 articles representing 45 primary studies aged between 5 to 12 and examined particular environmental features like fixed structures, natural elements, floor marking, loose parts or equipment and available play area.
* Pereira et al. (2024) found positive association between outdoor play space features and children's behaviours. However, there was substantial variation between studies so the review could not establish clear conclusions about the effects of particular environmental features.

|Key points
* Beekhuizen et al. (2025) identified personal, interacting and environmental factors that could facilitate or restrict inclusive outdoor play.
* Social relationships and familiarity affected participation, with children with disabilities reporting more barriers to inclusive outdoor play (Beekhuizen et al., 2025).
* Associations between outdoor play and social-emotional competence varied across some population groups and play contexts (Ferguson et al., 2025).

== '''What does recent research show about outdoor play and children's emotional well-being?''' ==
* Recent research has examined various aspects of outdoor play and children's emotional well-being and provides mixed evidence. These include emotional dysregulation (Lee et al., 2025), social-emotional competence (Ferguson et al., 2025), positive and negative affect (Poulos et al., 2026), and internalising and externalising symptoms (Dodd et al., 2026).
* Ferguson et al. (2025) found that more frequent outdoor play was associated with better social-emotional competence. However, the associations varied across some ethnic groups and according to whether outdoor play occurred on school days or weekends.
* Dodd et al. (2026) provides longitudinal evidence from 4,151 children from the Growing Up in Scotland study. Children who played outdoors more frequently between approximately 2 and 4 years of age were more likely to follow a trajectory of low and stable internalising and externalising symptoms through to age 8.
* Poulos et al. (2026) examined children's emotional state immediately after recess during hot weather. Among 317 children in years 4 and 5, the positive effect was higher after outdoor recess and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Together, these studies show evidence of associations between outdoor play or outdoor recess and several aspects of emotional well-being. However, the studies did not show the common effect because the study differ in children's ages, research designs, measures of outdoor play, and emotional outcomes.
=== '''Consistency of recent research findings''' ===
* Recent findings do not show the same effect across all outcomes. Ferguson et al. (2025) found that more frequent outdoor play was associated with lower total difficulties and greater prosocial behaviour. In contrast, Davenport et al. (2024) found that most associations between outdoor play and the physical, cognitive and social-emotional developmental indicators examined were not statistically significant. Therefore, the recent studies have not found significant association across all developmental outcomes.
* Findings can also differ according to the emotional outcome being measured. Poulos et al. (2026) found higher positive affect after outdoor and gymnasium recess than after classroom recess, but no significant differences in negative affect between the three recess settings. Lee et al. (2025) found that lower emotional dysregulation associated with greater afternoon outdoor play but higher emotional dysregulation is associated with greater outdoor play earlier and later in the day.
* Dodd et al. (2026) provides longer-term evidence. More frequent outdoor play during the preschool years predicted lower odds of belonging to the increasing or decreasing internalising and externalising symptom trajectory groups, relative to the normative low and stable group. This shows an association between early outdoor play and mental-health symptom trajectories across childhood rather than an emotional outcome measured at one point in time.
* Associations may also vary across children and outdoor play contexts. Ferguson et al. (2025) reported differences according to ethnicity and whether outdoor play occurred on school days or weekends.
* Recent findings suggest that associations between outdoor play and emotional well-being are not the same across all outcomes, children and play contexts. The studies differ in children's age, research designs, measures of outdoor play, and emotional outcomes. Thus, findings should not be treated as evidence of one single effect.
=== '''Strengths and limitations of current research''' ===
* Longitudinal research strengthens the evidence concerning temporal relationship. Dodd et al. (2026) analysed 4,151 children from the Growing Up in Scotland study. Outdoor play was measured at approximately 2, 3 and 4 years of age, while internalising and externalising symptoms were measured at approximately 4, 5, 6 and 8 years. This allowed the researchers to examine whether early outdoor play predicted different mental-health symptom trajectories across childhood.
* Although, longitudinal evidence does not establish cause and effect. Dodd et al. (2026) identified reliance on parent report measures as a key limitation, while Lee et al. (2025) also discussed about the possibility of reverse causation when interpreting associations between the timing of outdoor play and emotional dysregulation.
* Measurement of outdoor play is another important consideration. Davenport et al. (2024) examined both parent reported and device measured outdoor play and also tested whether associations were independent of outdoor moderate to vigorous physical activity. This approach distinguishes outdoor play from outdoor physical activity rather than interchangeable measures.
* Limitations are also present across the wider outdoor play literature. De Lannoy et al. (2023) identified 275 Canadian outdoor play publications and found that cross sectional study design was most common. Mental and emotional development had received less research attention in comparison to physical health and development.

As shown in table 2, the recent evidence has different methodological strengths and limitations. Longitudinal data provide stronger evidence about temporal ordering than cross-sectional studies, while the use of parent-reported and device-measured outdoor play addresses some measurement concerns. However, much of the evidence remains observational, several studies rely on parent-reported measures, and differences in emotional outcomes and play contexts limit the direct comparison between studies.
{| class="wikitable"
|Key points
* Recent studies report positive, mixed and non-significant findings across different emotional outcomes and measures of outdoor play (Davenport et al., 2024; Ferguson et al., 2025).
* Lee et al. (2025) and Dodd et al. (2026) found associations across different emotional outcomes and time frames, from emotional dysregulation to later symptom trajectories.
* Differences in study design, measurement, children's age and play context mean the findings should not be interpreted as one consistent effect of outdoor play on emotional well-being.

== '''How do families, communities and schools support outdoor play opportunities?''' ==
* Opportunities for outdoor play are influenced by children's social and physical environments. Beekhuizen et al. (2025) identified parents, outdoor play environments, communities and time constraints as environmental factors that could act as facilitators or barriers to inclusive outdoor play.
* Support for outdoor play also involves whether children can participate with other children. Beekhuizen et al. (2025) identified experiencing autonomy, growing up together, making contact and adapting ways of playing as factors involved in inclusive outdoor play.
* The 2025 Position Statement on Active Outdoor Play recommends increasing opportunities for active outdoor play in settings where people live, learn, work and play. It also emphasises collaboration across sectors, settings and societies to support equitable access to active outdoor play (Lee et al., 2025).
=== '''Families''' ===
* Beekhuizen et al. (2025) identified parents as an environmental factor in inclusive outdoor play. Children with disabilities described parents as important in encouraging participation and, for some children, helping to explain their disability to other children.
* Experiencing autonomy was identified as an important personal factor. Some children with disabilities wanted their parents to allow them freedom during outdoor play. Some preferred their parents not to accompany them to the playground, while others were comfortable with parents remaining at a reasonable distance (Beekhuizen et al., 2025).
* These findings indicate that parental support and children's autonomy can both be relevant to opportunities for outdoor play. For some children with disabilities, support could be necessary for participation while opportunities to play more independently were also valued (Beekhuizen et al., 2025).
* Beekhuizen et al. (2025) identified parental support as important for facilitating positive inclusive play experiences. The authors also recommended providing children and parents with knowledge about disabilities and possible adaptations that can support participation
* Family level opportunities also need to be interpreted alongside the time constraints. Some children attending special education described long journeys between school and home that reduced the time available for outdoor play (Beekhuizen et al., 2025). This means that opportunities for outdoor play cannot be interpreted only in terms of children's or parents' preferences.
=== '''Communities''' ===
* Beekhuizen et al. (2025) identified communities and the outdoor play environment as environmental factors in inclusive outdoor play. Children described physically and socially safe playgrounds as important. While barriers included structure of playgrounds that made participation difficult for some children with disabilities.
* The social environment of a community was also important. Children with disabilities described smaller communities, such as villages and schools, the places where other children and parents could become more familiar with disability. This familiarity was associated with greater acceptance and stronger connections with other children (Beekhuizen et al., 2025).
* Recent observational research also shows that physical access alone does not explain inclusive outdoor play. Beekhuizen et al. (2026) observed 63 children with and without disabilities during six inclusive outdoor play sessions and assessed both children's playfulness and environmental supportiveness. Children with disabilities showed significantly lower playfulness scores indicating that opportunities for inclusive play were not experienced equally.
* The 2025 Position Statement on Active Outdoor Play recommends collaboration across sectors, settings and societies to preserve, promote and value equitable access to active outdoor play. This places responsibility for outdoor play opportunities across communities and wider systems rather than on children and families alone (Lee et al., 2025).
=== '''Schools''' ===
* Schools can provide opportunities for children with and without disabilities to become familiar with one another. Beekhuizen et al. (2025) identified growing up together and making contact as interacting factors in inclusive outdoor play. Children described familiarity with other children as making contact easier.
* School circumstances can also affect the time and opportunities available for outdoor play. Some children attending special primary education described long travel times between school and home as reducing the time available to play outdoors. Beekhuizen et al. (2025) identified these experiences under time constraints.
* Recess provides another school setting in which children's emotional experiences have been examined. Poulos et al. (2026) studied 317 Year 4 and 5 children during extreme heat weather and found significantly higher positive affect after outdoor and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Poulos et al. (2026) identified implications for school health, policy and equity, including the need for heat adaptive infrastructure to support access to recess environments during extreme heat. However, the findings do not show that outdoor recess is always better than indoor recess because positive affect was also higher following gymnasium recess.

|Scenario
Two primary school aged children A and B enjoy playing outdoors. They both lived near the same playground. Child A was very familiar with the playground and knows several other children who play there and easily join the games. While child B has disability, uses mobility device and does not know other children at playground. Some parts of the playground are difficult to access and joining other children who are already playing can also be challenging. Child B's parents can provide support, although the child also prefers to play more independently.
Consider both children can access the same playground, but do they have same level opportunities to take part in outdoor play?

'''''<u>Note: Answers to the quiz is 1: True and 2 False</u>'''''
== '''Conclusion''' ==
* Outdoor play and children's emotional well-being are measured in different ways across recent research. Outdoor play is not equivalent to outdoor physical activity, while emotional outcomes include emotional dysregulation, social-emotional competence, positive and negative affect, and internalising and externalising symptoms. These differences need to be considered when findings across studies are compared.
* Research also provides mixed evidence about how outdoor play may be related to emotional well-being. Gross's (2015) emotion-regulation framework can be applied to emotional situations experienced during play, but it does not show that outdoor play improves emotion regulation. Lee et al. (2025) provides more direct evidence of a possible cognitive process, with working memory statistically mediating the association between afternoon outdoor play and lower emotional dysregulation. However, this observational finding does not establish causation.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Overall, current research supports an association between outdoor play and some aspects of children's emotional well-being but does not establish one consistent effect. Differences in measurement, research design, children and play contexts remain important when interpreting the evidence.

|'''Case study: part 1'''
'''Imagine this....'''[[File:School children happily playing in playground.jpg|thumb|'''Figure 1.''' ''Children engaged in outdoor play.'']]A child arrives at playground and joins a group of children who are already playing. The children are making their own game and deciding the rules as they play. At first, child enjoys choosing where and what to play and moving between the different activities. During the game, another child changes the rules of the game and argument breaks out. The child becomes frustrated and avoids the activity. After watching for short time, the child returns, suggests for new idea to continue game and re-joins the group. How might experiences like this during outdoor play influence children's emotional well-being? Emotional regulation theory provides one way of understanding on how children may respond to emotional situations during play (see figure 1) (Gross, 2015).
|}
Outdoor play can involve more than physical movements. It is more than simply being outside and engage in the activities across playgrounds, gardens, streets and natural spaces. Outdoor play involves exploration, social interaction, choice and challenge and engagement with surrounding environment (Dodd et al.,2026; Pereira et al.,2024). These experiences may create emotional situations in which children need to respond to frustration, disagreement, uncertainty or excitement. Gross (2015) [[emotional regulation]] theory provides a [[psychological]] explanation for how children may recognise and respond to these emotional situations. Outdoor play experiences are also shaped by the environment where play takes place. Experiences are shaped by the different opportunities provided by different physical and social environments, which means the same outdoor space may not provide the same experience for every child (Morgenthaler et al.,2024).This chapter examines how [[Emotional regulation|emotional,]] [[Cognitive psychology|cognitive]], social and environmental processes may help explain the relationship between outdoor play and children's emotional well-being.

Outdoor play and children's emotional well-being are not measured as single and consistent concepts across recent research. Outdoor play may be examined as voluntary and intrinsically motivated activity, self directed play, parent reported outdoor play, or device-measured outdoor play activity. It should also be distinguished from outdoor moderate to vigorous physical activity because these measures do not represent the same behaviour (Davenport et al., 2025). Children's emotional well-being is also examined through different outcomes, that includes [[emotional regulation]], social-emotional competence, positive and negative affect, and internalising or externalising symptoms. These differences are significant because outdoor play and emotional well-being are not measured as single, consistent constructs across research.
=== Outdoor play ===
Outdoor play is voluntary and and intrinsically motivated activity that occurs in outdoor environments like gardens, playgrounds, parks and natural spaces (Dodd et al., 2026). Free play can be also self-directed, which means children to freely interact with the environment and have autonomy to make choices about their activities (Biino et al., 2025). Outdoor play should not be treated as same as outdoor physical activity. Davenport et al., (2025) examined outdoor play separately from outdoor moderate- to- vigorous physical activity (MVPA). This distinction is significant because research on children's outdoor play is not necessarily measuring the same behaviour as research on the intensity of physical activity.
=== Children's emotional well-being ===
Children's emotional well-being is not represented by single common outcome across recent outdoor play research. Emotional dysregulation has been examined in relation to the amount and timing of outdoor play (Lee et al., 2025), while social-emotional competence includes difficulties and [[Prosocial behavior/Keywords/Definitions|prosocial behaviour]] (Ferguson et al., 2025). Other studies have examined positive and negative affect following recess (Poulos et al., 2026) and trajectories of internalising and externalising symptoms across childhood (Dodd et al., 2026). These outcomes represent different aspects and timeframes of emotional functioning, so they should not be treated as equivalent when findings are compared.

As shown in Table 1, the studies do not measure the same aspect or time frame of children's emotional functioning. Affect immediately following recess should not be treated as equivalent to emotional dysregulation measured over time or trajectories of internalising and externalising symptoms across childhood. This difference need to be considered when examining whether outdoor play is associated with children's emotional well-being.

''What is being measured?''
{| class="wikitable"
| valign="top" |[[File:Children marbles.jpg|thumb|177x177px|'''Figure 3'''. ''Children may experience different emotional responses during social outdoor play'']]The child in the case study part 1 becomes frustrated when the rules of the game change. This immediate emotional response is different from a longer-term pattern of emotional dysregulation or internalising symptoms. When research findings are compared, it is important to consider which aspect of emotional well-being is measured.

== '''How does outdoor play influence children's emotional well-being?''' ==
Outdoor play may be related to children's emotional well-being through emotional, cognitive, and social processes. Possible pathways discussed in the recent research include [[Emotional regulation|emotion regulation]], working memory, social interaction, physical activity, connection with the nature and adventurous play. However, these pathways have not all been directly tested as mechanisms, and many of the outdoor play literatures remain observational (Dodd et al., 2026; de Lannoy et al.,2023). Psychological theory can help to explain how and why outdoor play experiences may influence children's emotional well-being. Although the evidence does not yet show that psychological processes cause the relationship between outdoor play and children's emotional well-being.
=== '''Emotion regulation''' ===
* [[w:Emotional_self-regulation|Emotional self-regulation]] regulation provides an understanding of how children manage emotional situations. Gross (2015) describes emotional regulation as a process involving identification, selection and implementation. Identification concerns deciding whether to regulate an emotion, selection concerns selecting regulation strategy and implementation concerns applying chosen response into practice.
* Gross (2015) describes {{ic|Use past tense here}} various forms of emotion regulation like situation selection, situation modification, attention deployment cognitive change and response modulation. During outdoor play a child may experience frustration, conflict, disagreement, uncertainty or changes to their activity. These process provide a psychological framework for understanding how people respond to emotional situations. This model can be applied to these outdoor play situations to consider how children might recognise emotional response, decide how to manage the situation, and act on that decision.
* However, this is an application of Gross (2015) theoretical framework to outdoor play. This study did not examine whether outdoor play influence to children's emotion regulation.
=== '''Working memory and cognitive process''' ===
* Lee et al. (2025) examined [[w:Working_memory|working memory]] as a mediator between outdoor play and emotional dysregulation among 325 preschool children. Outdoor play was examined across three part of the day: wake-up to noon, noon to 6 pm and 6 pm to bedtime.
* The timing of outdoor play was important. More outdoor play between noon and 6 pm was related to lower emotional dysregulation. In contrast, more outdoor play before noon and after 6 pm was related to higher emotional dysregulation (Lee et al. 2025).
* Lee et al (2025) found that more outdoor play from noon to 6 pm was associated with better working memory (b=1.61, p<.05) and better working memory was associated with lower emotional dysregulation (b= -0.08, p< .01). This relation between noon to 6pm outdoor play and emotional dysregulation as no longer statistically significant when working memory was included in the analysis. As a result it is reported as full mediation.
* The findings suggest that working memory can be one cognitive functioning process involved in the association between outdoor play and emotional regulation. However, statistical mediation in an observational study which does not prove that outdoor play caused better working memory or emotional regulation. Lee et al. (2025) called for further research examining both immediate and longer-term effects of outdoor play on working memory and emotion regulation.
{{ic|Add an APA style table caption}}
{| class="wikitable"
|Key points
* Lee et al. (2025) found that associations between outdoor play and emotional dysregulation differed according to time of day.
* Working memory statistically mediated the association between afternoon outdoor play and lower emotional dysregulation in Lee et al. (2025).
* Dodd et al. (2026) found that more frequent preschool outdoor play predicted lower odds of non-normative internalising and externalising symptom trajectories.
|}
== '''Social and environmental influences on outdoor play''' ==
* Outdoor play opportunities are shaped by more than the physical being outdoor space. Beekhuizen et al. (2025) interviewed 40 children aged 6 to 12, with and without disabilities about facilitators and barriers to inclusive outdoor play. The findings were identified personal factor, interacting factors and environmental factors.
* Personal factors included experiencing [[w:Autonomy|autonomy]], and children's feelings of physical and social limitations. Interacting factors included making contact, growing up together, and adopting the ways of playing. Environmental factors included parents, outdoor play environments, communities, and time constrains (Beekhuizen et al., 2025).
* Opportunities for outdoor play was not experienced in the same way by all children. Beekhuizen et al. (2025) found that children with disabilities experienced more barriers than children with no disability. The challenges were related to making contact with other children, adopting play and the physical play environment.
* Ferguson et al. (2025) examined the association between outdoor play and children's social-emotional competence. In a cross sectional analysis of 2568 children, aged 7.1 to 12.6 years from multi-ethnic urban cohort found that outdoor play was associated with better social-emotional competence. However, the association was differed across ethnicity, and weekday or weekend outdoor play.
* Ferguson et al. (2025) also examined area deprivation. The relation between outdoor play and social-emotional competence appeared stronger in less deprived area, although the statistical evidence for the differences by deprivation was significantly weak.
=== '''Social relationship and inclusion''' ===
* Beekhuizen et al. (2025) identified making contact and growing up together as interacting factors in inclusive outdoor play. Some children described familiarity with other children as an easy way to approach, communication and play together. Making contact could also be a barrier when children approaching to another unfamiliar children or joining in play who were already playing.
* Children also described the need to adopt games so that children with different abilities could participate. School and communities were identified settings where children with and without disabilities could become familiar with each other (Beekhuizen et al., 2025).
* In the recent observational research by Beekhuizen et al. (2026) observed outdoor play among children with and without disability. The researchers found that getting to know each other, making contact and interaction while playing together as process of inclusive outdoor play. These observational findings showed that familiarity and making contact determine social and inclusive play because children chose to play with children they already knew.
* Ferguson et al. (2025) also found that the association between outdoor play and social emotional competence was not the same across all ethnic and deprivation groups. In the cross sectional analysis of 2568 children aged 7.1 to 12.6 years from multi ethnic urban cohort, outdoor play was associated with better social-emotional competence. However, associations varies across same ethnic groups and according to weekday or weekend outdoor play.
=== '''Autonomy, parents and time''' ===
* Experiencing autonomy was identified as a personal factor in inclusive outdoor play. Children having some independence during outdoor play could promote their sense of independence over what they do and who they play with (Beekhuizen et al., 2025).
* Experiencing autonomy also included opportunities to play without direct involvement of parents. Some children with disabilities described wanting to play outside independently, although parental support could make outdoor play possible (Beekhuizen et al., 2025)
* Parents were identified as an environmental factors. Beekhuizen et al. (2025) found that parental involvement could support children's participation in outdoor play, specially when child needed help to access or participate in outdoor play.
* Time constraints were considered as another environmental factor. Some children with disabilities were described as having limited outdoor play time due to parents work schedule, after-school arrangements or longer travel distance between home and school (Beekhuizen et al., 2025)
=== '''Outdoor environments and accessibility''' ===
* The outdoor play environment was identified as an environmental factor that could could support or restrict inclusive outdoor play. Children described both physical and social aspects of outdoor play environments. For example, children discussed the importance of physical and social safety, including traffic near playgrounds and disputes among children. Accessibility was particularly relevant to children with disabilities because opportunities for inclusive outdoor play could be affected by play environments and physical abilities (Beekhuizen et al., 2025).
* Pereira et al. (2024) provided evidence about the physical features of outdoor play spaces. Their systematic review included 51 articles representing 45 primary studies aged between 5 to 12 and examined particular environmental features like fixed structures, natural elements, floor marking, loose parts or equipment and available play area.
* Pereira et al. (2024) found positive association between outdoor play space features and children's behaviours. However, there was substantial variation between studies so the review could not establish clear conclusions about the effects of particular environmental features.

|Key points
* Beekhuizen et al. (2025) identified personal, interacting and environmental factors that could facilitate or restrict inclusive outdoor play.
* Social relationships and familiarity affected participation, with children with disabilities reporting more barriers to inclusive outdoor play (Beekhuizen et al., 2025).
* Associations between outdoor play and social-emotional competence varied across some population groups and play contexts (Ferguson et al., 2025).

== '''What does recent research show about outdoor play and children's emotional well-being?''' ==
* Recent research has examined various aspects of outdoor play and children's emotional well-being and provides mixed evidence. These include emotional dysregulation (Lee et al., 2025), social-emotional competence (Ferguson et al., 2025), positive and negative affect (Poulos et al., 2026), and internalising and externalising symptoms (Dodd et al., 2026).
* Ferguson et al. (2025) found that more frequent outdoor play was associated with better social-emotional competence. However, the associations varied across some ethnic groups and according to whether outdoor play occurred on school days or weekends.
* Dodd et al. (2026) provides longitudinal evidence from 4,151 children from the Growing Up in Scotland study. Children who played outdoors more frequently between approximately 2 and 4 years of age were more likely to follow a trajectory of low and stable internalising and externalising symptoms through to age 8.
* Poulos et al. (2026) examined children's emotional state immediately after recess during hot weather. Among 317 children in years 4 and 5, the positive effect was higher after outdoor recess and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Together, these studies show evidence of associations between outdoor play or outdoor recess and several aspects of emotional well-being. However, the studies did not show the common effect because the study differ in children's ages, research designs, measures of outdoor play, and emotional outcomes.
=== '''Consistency of recent research findings''' ===
* Recent findings do not show the same effect across all outcomes. Ferguson et al. (2025) found that more frequent outdoor play was associated with lower total difficulties and greater prosocial behaviour. In contrast, Davenport et al. (2024) found that most associations between outdoor play and the physical, cognitive and social-emotional developmental indicators examined were not statistically significant. Therefore, the recent studies have not found significant association across all developmental outcomes.
* Findings can also differ according to the emotional outcome being measured. Poulos et al. (2026) found higher positive affect after outdoor and gymnasium recess than after classroom recess, but no significant differences in negative affect between the three recess settings. Lee et al. (2025) found that lower emotional dysregulation associated with greater afternoon outdoor play but higher emotional dysregulation is associated with greater outdoor play earlier and later in the day.
* Dodd et al. (2026) provides longer-term evidence. More frequent outdoor play during the preschool years predicted lower odds of belonging to the increasing or decreasing internalising and externalising symptom trajectory groups, relative to the normative low and stable group. This shows an association between early outdoor play and mental-health symptom trajectories across childhood rather than an emotional outcome measured at one point in time.
* Associations may also vary across children and outdoor play contexts. Ferguson et al. (2025) reported differences according to ethnicity and whether outdoor play occurred on school days or weekends.
* Recent findings suggest that associations between outdoor play and emotional well-being are not the same across all outcomes, children and play contexts. The studies differ in children's age, research designs, measures of outdoor play, and emotional outcomes. Thus, findings should not be treated as evidence of one single effect.
=== '''Strengths and limitations of current research''' ===
* Longitudinal research strengthens the evidence concerning temporal relationship. Dodd et al. (2026) analysed 4,151 children from the Growing Up in Scotland study. Outdoor play was measured at approximately 2, 3 and 4 years of age, while internalising and externalising symptoms were measured at approximately 4, 5, 6 and 8 years. This allowed the researchers to examine whether early outdoor play predicted different mental-health symptom trajectories across childhood.
* Although, longitudinal evidence does not establish cause and effect. Dodd et al. (2026) identified reliance on parent report measures as a key limitation, while Lee et al. (2025) also discussed about the possibility of reverse causation when interpreting associations between the timing of outdoor play and emotional dysregulation.
* Measurement of outdoor play is another important consideration. Davenport et al. (2024) examined both parent reported and device measured outdoor play and also tested whether associations were independent of outdoor moderate to vigorous physical activity. This approach distinguishes outdoor play from outdoor physical activity rather than interchangeable measures.
* Limitations are also present across the wider outdoor play literature. De Lannoy et al. (2023) identified 275 Canadian outdoor play publications and found that cross sectional study design was most common. Mental and emotional development had received less research attention in comparison to physical health and development.

|}
As shown in table 2, the recent evidence has different methodological strengths and limitations. Longitudinal data provide stronger evidence about temporal ordering than cross-sectional studies, while the use of parent-reported and device-measured outdoor play addresses some measurement concerns. However, much of the evidence remains observational, several studies rely on parent-reported measures, and differences in emotional outcomes and play contexts limit the direct comparison between studies.
{| class="wikitable"
|Key points
* Recent studies report positive, mixed and non-significant findings across different emotional outcomes and measures of outdoor play (Davenport et al., 2024; Ferguson et al., 2025).
* Lee et al. (2025) and Dodd et al. (2026) found associations across different emotional outcomes and time frames, from emotional dysregulation to later symptom trajectories.
* Differences in study design, measurement, children's age and play context mean the findings should not be interpreted as one consistent effect of outdoor play on emotional well-being.
|}
== '''How do families, communities and schools support outdoor play opportunities?''' ==
* Opportunities for outdoor play are influenced by children's social and physical environments. Beekhuizen et al. (2025) identified parents, outdoor play environments, communities and time constraints as environmental factors that could act as facilitators or barriers to inclusive outdoor play.
* Support for outdoor play also involves whether children can participate with other children. Beekhuizen et al. (2025) identified experiencing autonomy, growing up together, making contact and adapting ways of playing as factors involved in inclusive outdoor play.
* The 2025 Position Statement on Active Outdoor Play recommends increasing opportunities for active outdoor play in settings where people live, learn, work and play. It also emphasises collaboration across sectors, settings and societies to support equitable access to active outdoor play (Lee et al., 2025).
=== '''Families''' ===
* Beekhuizen et al. (2025) identified parents as an environmental factor in inclusive outdoor play. Children with disabilities described parents as important in encouraging participation and, for some children, helping to explain their disability to other children.
* Experiencing autonomy was identified as an important personal factor. Some children with disabilities wanted their parents to allow them freedom during outdoor play. Some preferred their parents not to accompany them to the playground, while others were comfortable with parents remaining at a reasonable distance (Beekhuizen et al., 2025).
* These findings indicate that parental support and children's autonomy can both be relevant to opportunities for outdoor play. For some children with disabilities, support could be necessary for participation while opportunities to play more independently were also valued (Beekhuizen et al., 2025).
* Beekhuizen et al. (2025) identified parental support as important for facilitating positive inclusive play experiences. The authors also recommended providing children and parents with knowledge about disabilities and possible adaptations that can support participation
* Family level opportunities also need to be interpreted alongside the time constraints. Some children attending special education described long journeys between school and home that reduced the time available for outdoor play (Beekhuizen et al., 2025). This means that opportunities for outdoor play cannot be interpreted only in terms of children's or parents' preferences.
=== '''Communities''' ===
* Beekhuizen et al. (2025) identified communities and the outdoor play environment as environmental factors in inclusive outdoor play. Children described physically and socially safe playgrounds as important. While barriers included structure of playgrounds that made participation difficult for some children with disabilities.
* The social environment of a community was also important. Children with disabilities described smaller communities, such as villages and schools, the places where other children and parents could become more familiar with disability. This familiarity was associated with greater acceptance and stronger connections with other children (Beekhuizen et al., 2025).
* Recent observational research also shows that physical access alone does not explain inclusive outdoor play. Beekhuizen et al. (2026) observed 63 children with and without disabilities during six inclusive outdoor play sessions and assessed both children's playfulness and environmental supportiveness. Children with disabilities showed significantly lower playfulness scores indicating that opportunities for inclusive play were not experienced equally.
* The 2025 Position Statement on Active Outdoor Play recommends collaboration across sectors, settings and societies to preserve, promote and value equitable access to active outdoor play. This places responsibility for outdoor play opportunities across communities and wider systems rather than on children and families alone (Lee et al., 2025).
=== '''Schools''' ===
* Schools can provide opportunities for children with and without disabilities to become familiar with one another. Beekhuizen et al. (2025) identified growing up together and making contact as interacting factors in inclusive outdoor play. Children described familiarity with other children as making contact easier.
* School circumstances can also affect the time and opportunities available for outdoor play. Some children attending special primary education described long travel times between school and home as reducing the time available to play outdoors. Beekhuizen et al. (2025) identified these experiences under time constraints.
* Recess provides another school setting in which children's emotional experiences have been examined. Poulos et al. (2026) studied 317 Year 4 and 5 children during extreme heat weather and found significantly higher positive affect after outdoor and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Poulos et al. (2026) identified implications for school health, policy and equity, including the need for heat adaptive infrastructure to support access to recess environments during extreme heat. However, the findings do not show that outdoor recess is always better than indoor recess because positive affect was also higher following gymnasium recess.

|Scenario
Two primary school aged children A and B enjoy playing outdoors. They both lived near the same playground. Child A was very familiar with the playground and knows several other children who play there and easily join the games. While child B has disability, uses mobility device and does not know other children at playground. Some parts of the playground are difficult to access and joining other children who are already playing can also be challenging. Child B's parents can provide support, although the child also prefers to play more independently.
Consider both children can access the same playground, but do they have same level opportunities to take part in outdoor play?

'''''<u>Note: Answers to the quiz is 1: True and 2 False</u>'''''
== '''Conclusion''' ==
* Outdoor play and children's emotional well-being are measured in different ways across recent research. Outdoor play is not equivalent to outdoor physical activity, while emotional outcomes include emotional dysregulation, social-emotional competence, positive and negative affect, and internalising and externalising symptoms. These differences need to be considered when findings across studies are compared.
* Research also provides mixed evidence about how outdoor play may be related to emotional well-being. Gross's (2015) emotion-regulation framework can be applied to emotional situations experienced during play, but it does not show that outdoor play improves emotion regulation. Lee et al. (2025) provides more direct evidence of a possible cognitive process, with working memory statistically mediating the association between afternoon outdoor play and lower emotional dysregulation. However, this observational finding does not establish causation.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Overall, current research supports an association between outdoor play and some aspects of children's emotional well-being but does not establish one consistent effect. Differences in measurement, research design, children and play contexts remain important when interpreting the evidence.

__TOC__
== Overview ==
{| class="wikitable"
|'''Case study: part 1'''
'''Imagine this....'''[[File:School children happily playing in playground.jpg|thumb|'''Figure 1.''' ''Children engaged in outdoor play.'']]A child arrives at playground and joins a group of children who are already playing. The children are making their own game and deciding the rules as they play. At first, child enjoys choosing where and what to play and moving between the different activities. During the game, another child changes the rules of the game and argument breaks out. The child becomes frustrated and avoids the activity. After watching for short time, the child returns, suggests for new idea to continue game and re-joins the group. How might experiences like this during outdoor play influence children's emotional well-being? Emotional regulation theory provides one way of understanding on how children may respond to emotional situations during play (see figure 1) (Gross, 2015).
|}
Outdoor play can involve more than physical movements. It is more than simply being outside and engage in the activities across playgrounds, gardens, streets and natural spaces. Outdoor play involves exploration, social interaction, choice and challenge and engagement with surrounding environment (Dodd et al.,2026; Pereira et al.,2024). These experiences may create emotional situations in which children need to respond to frustration, disagreement, uncertainty or excitement. Gross (2015) [[emotional regulation]] theory provides a [[psychological]] explanation for how children may recognise and respond to these emotional situations. Outdoor play experiences are also shaped by the environment where play takes place. Experiences are shaped by the different opportunities provided by different physical and social environments, which means the same outdoor space may not provide the same experience for every child (Morgenthaler et al.,2024).This chapter examines how [[Emotional regulation|emotional,]] [[Cognitive psychology|cognitive]], social and environmental processes may help explain the relationship between outdoor play and children's emotional well-being.

Outdoor play and children's emotional well-being are not measured as single and consistent concepts across recent research. Outdoor play may be examined as voluntary and intrinsically motivated activity, self directed play, parent reported outdoor play, or device-measured outdoor play activity. It should also be distinguished from outdoor moderate to vigorous physical activity because these measures do not represent the same behaviour (Davenport et al., 2025). Children's emotional well-being is also examined through different outcomes, that includes [[emotional regulation]], social-emotional competence, positive and negative affect, and internalising or externalising symptoms. These differences are significant because outdoor play and emotional well-being are not measured as single, consistent constructs across research.
=== Outdoor play ===
Outdoor play is voluntary and and intrinsically motivated activity that occurs in outdoor environments like gardens, playgrounds, parks and natural spaces (Dodd et al., 2026). Free play can be also self-directed, which means children to freely interact with the environment and have autonomy to make choices about their activities (Biino et al., 2025). Outdoor play should not be treated as same as outdoor physical activity. Davenport et al., (2025) examined outdoor play separately from outdoor moderate- to- vigorous physical activity (MVPA). This distinction is significant because research on children's outdoor play is not necessarily measuring the same behaviour as research on the intensity of physical activity.
=== Children's emotional well-being ===
Children's emotional well-being is not represented by single common outcome across recent outdoor play research. Emotional dysregulation has been examined in relation to the amount and timing of outdoor play (Lee et al., 2025), while social-emotional competence includes difficulties and [[Prosocial behavior/Keywords/Definitions|prosocial behaviour]] (Ferguson et al., 2025). Other studies have examined positive and negative affect following recess (Poulos et al., 2026) and trajectories of internalising and externalising symptoms across childhood (Dodd et al., 2026). These outcomes represent different aspects and timeframes of emotional functioning, so they should not be treated as equivalent when findings are compared.

As shown in Table 1, the studies do not measure the same aspect or time frame of children's emotional functioning. Affect immediately following recess should not be treated as equivalent to emotional dysregulation measured over time or trajectories of internalising and externalising symptoms across childhood. This difference need to be considered when examining whether outdoor play is associated with children's emotional well-being.

''Children may experience different emotional responses during social outdoor play'']]The child in the case study part 1 becomes frustrated when the rules of the game change. This immediate emotional response is different from a longer-term pattern of emotional dysregulation or internalising symptoms. When research findings are compared, it is important to consider which aspect of emotional well-being is measured.

== '''How does outdoor play influence children's emotional well-being?''' ==
Outdoor play may be related to children's emotional well-being through emotional, cognitive, and social processes. Possible pathways discussed in the recent research include [[Emotional regulation|emotion regulation]], working memory, social interaction, physical activity, connection with the nature and adventurous play. However, these pathways have not all been directly tested as mechanisms, and many of the outdoor play literatures remain observational (Dodd et al., 2026; de Lannoy et al.,2023). Psychological theory can help to explain how and why outdoor play experiences may influence children's emotional well-being. Although the evidence does not yet show that psychological processes cause the relationship between outdoor play and children's emotional well-being.
=== '''Emotion regulation''' ===
Emotion regulation provides a psychological framework for understanding how children may manage emotional situations during outdoor play. Gross (2025) described emotional regulation as a process involving identification, selection and implementation. Identification concerns deciding whether to regulate an emotion, selection concerns selecting regulation strategy and implementation concerns applying chosen response into practice. Gross (2015) also described situation selection, situation modification, attention deployment cognitive change and response modulation. During outdoor play, children may experience frustration, conflict, disagreement, uncertainty or changes to their activity. Gross framework can be applied to these situations to consider how a children recognise an emotional response, choose strategies to manage and act on chosen strategies. However, Gross (2015) did not examine outdoor play, so applying the framework does not show that outdoor play improves children's emotion regulation.
{| class="wikitable"
| valign="top" |'''Case study: Part 3'''[[File:14Y Ncdc july 5th-802.jpg|thumb|202x202px|'''Figure 4'''. ''Children can respond differently to situations that occur during outdoor play.'']]When the rule of game change, the child becomes frustrated and decided to step away. After a short time the child returns and suggests for different way to continue the game (see Figure 4). Suggesting a change to the game can be considered an example of situation modification. This shows how Gross's emotion regulation framework can be applied to an emotional situation during outdoor play.

can be used to consider how a child decides whether to regulate
process provide a psychological framework for understanding how people respond to emotional situations. This model can be applied to these outdoor play situations to consider how children might recognise emotional response, decide how to manage the situation, and act on that decision.
* However, this is an application of Gross (2015) theoretical framework to outdoor play. This study did not examine whether outdoor play influence to children's emotion regulation.
=== '''Working memory and cognitive process''' ===
* Lee et al. (2025) examined [[w:Working_memory|working memory]] as a mediator between outdoor play and emotional dysregulation among 325 preschool children. Outdoor play was examined across three part of the day: wake-up to noon, noon to 6 pm and 6 pm to bedtime.
* The timing of outdoor play was important. More outdoor play between noon and 6 pm was related to lower emotional dysregulation. In contrast, more outdoor play before noon and after 6 pm was related to higher emotional dysregulation (Lee et al. 2025).
* Lee et al (2025) found that more outdoor play from noon to 6 pm was associated with better working memory (b=1.61, p<.05) and better working memory was associated with lower emotional dysregulation (b= -0.08, p< .01). This relation between noon to 6pm outdoor play and emotional dysregulation as no longer statistically significant when working memory was included in the analysis. As a result it is reported as full mediation.
* The findings suggest that working memory can be one cognitive functioning process involved in the association between outdoor play and emotional regulation. However, statistical mediation in an observational study which does not prove that outdoor play caused better working memory or emotional regulation. Lee et al. (2025) called for further research examining both immediate and longer-term effects of outdoor play on working memory and emotion regulation.

|Key points
* Lee et al. (2025) found that associations between outdoor play and emotional dysregulation differed according to time of day.
* Working memory statistically mediated the association between afternoon outdoor play and lower emotional dysregulation in Lee et al. (2025).
* Dodd et al. (2026) found that more frequent preschool outdoor play predicted lower odds of non-normative internalising and externalising symptom trajectories.

== '''Social and environmental influences on outdoor play''' ==
* Outdoor play opportunities are shaped by more than the physical being outdoor space. Beekhuizen et al. (2025) interviewed 40 children aged 6 to 12, with and without disabilities about facilitators and barriers to inclusive outdoor play. The findings were identified personal factor, interacting factors and environmental factors.
* Personal factors included experiencing [[w:Autonomy|autonomy]], and children's feelings of physical and social limitations. Interacting factors included making contact, growing up together, and adopting the ways of playing. Environmental factors included parents, outdoor play environments, communities, and time constrains (Beekhuizen et al., 2025).
* Opportunities for outdoor play was not experienced in the same way by all children. Beekhuizen et al. (2025) found that children with disabilities experienced more barriers than children with no disability. The challenges were related to making contact with other children, adopting play and the physical play environment.
* Ferguson et al. (2025) examined the association between outdoor play and children's social-emotional competence. In a cross sectional analysis of 2568 children, aged 7.1 to 12.6 years from multi-ethnic urban cohort found that outdoor play was associated with better social-emotional competence. However, the association was differed across ethnicity, and weekday or weekend outdoor play.
* Ferguson et al. (2025) also examined area deprivation. The relation between outdoor play and social-emotional competence appeared stronger in less deprived area, although the statistical evidence for the differences by deprivation was significantly weak.
=== '''Social relationship and inclusion''' ===
* Beekhuizen et al. (2025) identified making contact and growing up together as interacting factors in inclusive outdoor play. Some children described familiarity with other children as an easy way to approach, communication and play together. Making contact could also be a barrier when children approaching to another unfamiliar children or joining in play who were already playing.
* Children also described the need to adopt games so that children with different abilities could participate. School and communities were identified settings where children with and without disabilities could become familiar with each other (Beekhuizen et al., 2025).
* In the recent observational research by Beekhuizen et al. (2026) observed outdoor play among children with and without disability. The researchers found that getting to know each other, making contact and interaction while playing together as process of inclusive outdoor play. These observational findings showed that familiarity and making contact determine social and inclusive play because children chose to play with children they already knew.
* Ferguson et al. (2025) also found that the association between outdoor play and social emotional competence was not the same across all ethnic and deprivation groups. In the cross sectional analysis of 2568 children aged 7.1 to 12.6 years from multi ethnic urban cohort, outdoor play was associated with better social-emotional competence. However, associations varies across same ethnic groups and according to weekday or weekend outdoor play.
=== '''Autonomy, parents and time''' ===
* Experiencing autonomy was identified as a personal factor in inclusive outdoor play. Children having some independence during outdoor play could promote their sense of independence over what they do and who they play with (Beekhuizen et al., 2025).
* Experiencing autonomy also included opportunities to play without direct involvement of parents. Some children with disabilities described wanting to play outside independently, although parental support could make outdoor play possible (Beekhuizen et al., 2025)
* Parents were identified as an environmental factors. Beekhuizen et al. (2025) found that parental involvement could support children's participation in outdoor play, specially when child needed help to access or participate in outdoor play.
* Time constraints were considered as another environmental factor. Some children with disabilities were described as having limited outdoor play time due to parents work schedule, after-school arrangements or longer travel distance between home and school (Beekhuizen et al., 2025)
=== '''Outdoor environments and accessibility''' ===
* The outdoor play environment was identified as an environmental factor that could could support or restrict inclusive outdoor play. Children described both physical and social aspects of outdoor play environments. For example, children discussed the importance of physical and social safety, including traffic near playgrounds and disputes among children. Accessibility was particularly relevant to children with disabilities because opportunities for inclusive outdoor play could be affected by play environments and physical abilities (Beekhuizen et al., 2025).
* Pereira et al. (2024) provided evidence about the physical features of outdoor play spaces. Their systematic review included 51 articles representing 45 primary studies aged between 5 to 12 and examined particular environmental features like fixed structures, natural elements, floor marking, loose parts or equipment and available play area.
* Pereira et al. (2024) found positive association between outdoor play space features and children's behaviours. However, there was substantial variation between studies so the review could not establish clear conclusions about the effects of particular environmental features.

|Key points
* Beekhuizen et al. (2025) identified personal, interacting and environmental factors that could facilitate or restrict inclusive outdoor play.
* Social relationships and familiarity affected participation, with children with disabilities reporting more barriers to inclusive outdoor play (Beekhuizen et al., 2025).
* Associations between outdoor play and social-emotional competence varied across some population groups and play contexts (Ferguson et al., 2025).
|}
== '''What does recent research show about outdoor play and children's emotional well-being?''' ==
* Recent research has examined various aspects of outdoor play and children's emotional well-being and provides mixed evidence. These include emotional dysregulation (Lee et al., 2025), social-emotional competence (Ferguson et al., 2025), positive and negative affect (Poulos et al., 2026), and internalising and externalising symptoms (Dodd et al., 2026).
* Ferguson et al. (2025) found that more frequent outdoor play was associated with better social-emotional competence. However, the associations varied across some ethnic groups and according to whether outdoor play occurred on school days or weekends.
* Dodd et al. (2026) provides longitudinal evidence from 4,151 children from the Growing Up in Scotland study. Children who played outdoors more frequently between approximately 2 and 4 years of age were more likely to follow a trajectory of low and stable internalising and externalising symptoms through to age 8.
* Poulos et al. (2026) examined children's emotional state immediately after recess during hot weather. Among 317 children in years 4 and 5, the positive effect was higher after outdoor recess and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Together, these studies show evidence of associations between outdoor play or outdoor recess and several aspects of emotional well-being. However, the studies did not show the common effect because the study differ in children's ages, research designs, measures of outdoor play, and emotional outcomes.
=== '''Consistency of recent research findings''' ===
* Recent findings do not show the same effect across all outcomes. Ferguson et al. (2025) found that more frequent outdoor play was associated with lower total difficulties and greater prosocial behaviour. In contrast, Davenport et al. (2024) found that most associations between outdoor play and the physical, cognitive and social-emotional developmental indicators examined were not statistically significant. Therefore, the recent studies have not found significant association across all developmental outcomes.
* Findings can also differ according to the emotional outcome being measured. Poulos et al. (2026) found higher positive affect after outdoor and gymnasium recess than after classroom recess, but no significant differences in negative affect between the three recess settings. Lee et al. (2025) found that lower emotional dysregulation associated with greater afternoon outdoor play but higher emotional dysregulation is associated with greater outdoor play earlier and later in the day.
* Dodd et al. (2026) provides longer-term evidence. More frequent outdoor play during the preschool years predicted lower odds of belonging to the increasing or decreasing internalising and externalising symptom trajectory groups, relative to the normative low and stable group. This shows an association between early outdoor play and mental-health symptom trajectories across childhood rather than an emotional outcome measured at one point in time.
* Associations may also vary across children and outdoor play contexts. Ferguson et al. (2025) reported differences according to ethnicity and whether outdoor play occurred on school days or weekends.
* Recent findings suggest that associations between outdoor play and emotional well-being are not the same across all outcomes, children and play contexts. The studies differ in children's age, research designs, measures of outdoor play, and emotional outcomes. Thus, findings should not be treated as evidence of one single effect.
=== '''Strengths and limitations of current research''' ===
* Longitudinal research strengthens the evidence concerning temporal relationship. Dodd et al. (2026) analysed 4,151 children from the Growing Up in Scotland study. Outdoor play was measured at approximately 2, 3 and 4 years of age, while internalising and externalising symptoms were measured at approximately 4, 5, 6 and 8 years. This allowed the researchers to examine whether early outdoor play predicted different mental-health symptom trajectories across childhood.
* Although, longitudinal evidence does not establish cause and effect. Dodd et al. (2026) identified reliance on parent report measures as a key limitation, while Lee et al. (2025) also discussed about the possibility of reverse causation when interpreting associations between the timing of outdoor play and emotional dysregulation.
* Measurement of outdoor play is another important consideration. Davenport et al. (2024) examined both parent reported and device measured outdoor play and also tested whether associations were independent of outdoor moderate to vigorous physical activity. This approach distinguishes outdoor play from outdoor physical activity rather than interchangeable measures.
* Limitations are also present across the wider outdoor play literature. De Lannoy et al. (2023) identified 275 Canadian outdoor play publications and found that cross sectional study design was most common. Mental and emotional development had received less research attention in comparison to physical health and development.

|}
As shown in table 2, the recent evidence has different methodological strengths and limitations. Longitudinal data provide stronger evidence about temporal ordering than cross-sectional studies, while the use of parent-reported and device-measured outdoor play addresses some measurement concerns. However, much of the evidence remains observational, several studies rely on parent-reported measures, and differences in emotional outcomes and play contexts limit the direct comparison between studies.
{| class="wikitable"
|Key points
* Recent studies report positive, mixed and non-significant findings across different emotional outcomes and measures of outdoor play (Davenport et al., 2024; Ferguson et al., 2025).
* Lee et al. (2025) and Dodd et al. (2026) found associations across different emotional outcomes and time frames, from emotional dysregulation to later symptom trajectories.
* Differences in study design, measurement, children's age and play context mean the findings should not be interpreted as one consistent effect of outdoor play on emotional well-being.
|}
== '''How do families, communities and schools support outdoor play opportunities?''' ==
* Opportunities for outdoor play are influenced by children's social and physical environments. Beekhuizen et al. (2025) identified parents, outdoor play environments, communities and time constraints as environmental factors that could act as facilitators or barriers to inclusive outdoor play.
* Support for outdoor play also involves whether children can participate with other children. Beekhuizen et al. (2025) identified experiencing autonomy, growing up together, making contact and adapting ways of playing as factors involved in inclusive outdoor play.
* The 2025 Position Statement on Active Outdoor Play recommends increasing opportunities for active outdoor play in settings where people live, learn, work and play. It also emphasises collaboration across sectors, settings and societies to support equitable access to active outdoor play (Lee et al., 2025).
=== '''Families''' ===
* Beekhuizen et al. (2025) identified parents as an environmental factor in inclusive outdoor play. Children with disabilities described parents as important in encouraging participation and, for some children, helping to explain their disability to other children.
* Experiencing autonomy was identified as an important personal factor. Some children with disabilities wanted their parents to allow them freedom during outdoor play. Some preferred their parents not to accompany them to the playground, while others were comfortable with parents remaining at a reasonable distance (Beekhuizen et al., 2025).
* These findings indicate that parental support and children's autonomy can both be relevant to opportunities for outdoor play. For some children with disabilities, support could be necessary for participation while opportunities to play more independently were also valued (Beekhuizen et al., 2025).
* Beekhuizen et al. (2025) identified parental support as important for facilitating positive inclusive play experiences. The authors also recommended providing children and parents with knowledge about disabilities and possible adaptations that can support participation
* Family level opportunities also need to be interpreted alongside the time constraints. Some children attending special education described long journeys between school and home that reduced the time available for outdoor play (Beekhuizen et al., 2025). This means that opportunities for outdoor play cannot be interpreted only in terms of children's or parents' preferences.
=== '''Communities''' ===
* Beekhuizen et al. (2025) identified communities and the outdoor play environment as environmental factors in inclusive outdoor play. Children described physically and socially safe playgrounds as important. While barriers included structure of playgrounds that made participation difficult for some children with disabilities.
* The social environment of a community was also important. Children with disabilities described smaller communities, such as villages and schools, the places where other children and parents could become more familiar with disability. This familiarity was associated with greater acceptance and stronger connections with other children (Beekhuizen et al., 2025).
* Recent observational research also shows that physical access alone does not explain inclusive outdoor play. Beekhuizen et al. (2026) observed 63 children with and without disabilities during six inclusive outdoor play sessions and assessed both children's playfulness and environmental supportiveness. Children with disabilities showed significantly lower playfulness scores indicating that opportunities for inclusive play were not experienced equally.
* The 2025 Position Statement on Active Outdoor Play recommends collaboration across sectors, settings and societies to preserve, promote and value equitable access to active outdoor play. This places responsibility for outdoor play opportunities across communities and wider systems rather than on children and families alone (Lee et al., 2025).
=== '''Schools''' ===
* Schools can provide opportunities for children with and without disabilities to become familiar with one another. Beekhuizen et al. (2025) identified growing up together and making contact as interacting factors in inclusive outdoor play. Children described familiarity with other children as making contact easier.
* School circumstances can also affect the time and opportunities available for outdoor play. Some children attending special primary education described long travel times between school and home as reducing the time available to play outdoors. Beekhuizen et al. (2025) identified these experiences under time constraints.
* Recess provides another school setting in which children's emotional experiences have been examined. Poulos et al. (2026) studied 317 Year 4 and 5 children during extreme heat weather and found significantly higher positive affect after outdoor and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Poulos et al. (2026) identified implications for school health, policy and equity, including the need for heat adaptive infrastructure to support access to recess environments during extreme heat. However, the findings do not show that outdoor recess is always better than indoor recess because positive affect was also higher following gymnasium recess.

Two primary school aged children A and B enjoy playing outdoors. They both lived near the same playground. Child A was very familiar with the playground and knows several other children who play there and easily join the games. While child B has disability, uses mobility device and does not know other children at playground. Some parts of the playground are difficult to access and joining other children who are already playing can also be challenging. Child B's parents can provide support, although the child also prefers to play more independently.
Consider both children can access the same playground, but do they have same level opportunities to take part in outdoor play?

'''''<u>Note: Answers to the quiz is 1: True and 2 False</u>'''''
== '''Conclusion''' ==
* Outdoor play and children's emotional well-being are measured in different ways across recent research. Outdoor play is not equivalent to outdoor physical activity, while emotional outcomes include emotional dysregulation, social-emotional competence, positive and negative affect, and internalising and externalising symptoms. These differences need to be considered when findings across studies are compared.
* Research also provides mixed evidence about how outdoor play may be related to emotional well-being. Gross's (2015) emotion-regulation framework can be applied to emotional situations experienced during play, but it does not show that outdoor play improves emotion regulation. Lee et al. (2025) provides more direct evidence of a possible cognitive process, with working memory statistically mediating the association between afternoon outdoor play and lower emotional dysregulation. However, this observational finding does not establish causation.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Overall, current research supports an association between outdoor play and some aspects of children's emotional well-being but does not establish one consistent effect. Differences in measurement, research design, children and play contexts remain important when interpreting the evidence.

{{title|Outdoor play and children's emotional well-being:<br>How does outdoor play influence children's emotional well-being?}}
__TOC__
== Overview ==
{| class="wikitable"
|'''Case study: part 1'''
'''Imagine this....'''[[File:School children happily playing in playground.jpg|thumb|'''Figure 1.''' ''Children engaged in outdoor play.'']]A child arrives at playground and joins a group of children who are already playing. The children are making their own game and deciding the rules as they play. At first, child enjoys choosing where and what to play and moving between the different activities. During the game, another child changes the rules of the game and argument breaks out. The child becomes frustrated and avoids the activity. After watching for short time, the child returns, suggests for new idea to continue game and re-joins the group. How might experiences like this during outdoor play influence children's emotional well-being? Emotional regulation theory provides one way of understanding on how children may respond to emotional situations during play (see figure 1) (Gross, 2015).
|}
Outdoor play can involve more than physical movements. It is more than simply being outside and engage in the activities across playgrounds, gardens, streets and natural spaces. Outdoor play involves exploration, social interaction, choice and challenge and engagement with surrounding environment (Dodd et al.,2026; Pereira et al.,2024). These experiences may create emotional situations in which children need to respond to frustration, disagreement, uncertainty or excitement. Gross (2015) [[emotional regulation]] theory provides a [[psychological]] explanation for how children may recognise and respond to these emotional situations. Outdoor play experiences are also shaped by the environment where play takes place. Experiences are shaped by the different opportunities provided by different physical and social environments, which means the same outdoor space may not provide the same experience for every child (Morgenthaler et al.,2024).This chapter examines how [[Emotional regulation|emotional,]] [[Cognitive psychology|cognitive]], social and environmental processes may help explain the relationship between outdoor play and children's emotional well-being.

[[File:Water-outdoor-people-girl-play-boy-938233.jpg|thumb|'''Figure 2'''. ''Visualise outdoor play as providing children with opportunities to explore, make choices, interact with others and respond to changing situations through activities such as water play.''|265x265px]]
Outdoor play and children's emotional well-being are not measured as single and consistent concepts across recent research. Outdoor play may be examined as voluntary and intrinsically motivated activity, self directed play, parent reported outdoor play, or device-measured outdoor play activity. It should also be distinguished from outdoor moderate to vigorous physical activity because these measures do not represent the same behaviour (Davenport et al., 2025). Children's emotional well-being is also examined through different outcomes, that includes [[emotional regulation]], social-emotional competence, positive and negative affect, and internalising or externalising symptoms. These differences are significant because outdoor play and emotional well-being are not measured as single, consistent constructs across research.
=== Outdoor play ===
Outdoor play is voluntary and and intrinsically motivated activity that occurs in outdoor environments like gardens, playgrounds, parks and natural spaces (Dodd et al., 2026). Free play can be also self-directed, which means children to freely interact with the environment and have autonomy to make choices about their activities (Biino et al., 2025). Outdoor play should not be treated as same as outdoor physical activity. Davenport et al., (2025) examined outdoor play separately from outdoor moderate- to- vigorous physical activity (MVPA). This distinction is significant because research on children's outdoor play is not necessarily measuring the same behaviour as research on the intensity of physical activity.
=== Children's emotional well-being ===
Children's emotional well-being is not represented by single common outcome across recent outdoor play research. Emotional dysregulation has been examined in relation to the amount and timing of outdoor play (Lee et al., 2025), while social-emotional competence includes difficulties and [[Prosocial behavior/Keywords/Definitions|prosocial behaviour]] (Ferguson et al., 2025). Other studies have examined positive and negative affect following recess (Poulos et al., 2026) and trajectories of internalising and externalising symptoms across childhood (Dodd et al., 2026). These outcomes represent different aspects and timeframes of emotional functioning, so they should not be treated as equivalent when findings are compared.

As shown in Table 1, the studies do not measure the same aspect or time frame of children's emotional functioning. Affect immediately following recess should not be treated as equivalent to emotional dysregulation measured over time or trajectories of internalising and externalising symptoms across childhood. This difference need to be considered when examining whether outdoor play is associated with children's emotional well-being.

''What is being measured?''
{| class="wikitable"
| valign="top" |[[File:Children marbles.jpg|thumb|177x177px|'''Figure 3'''. ''Children may experience different emotional responses during social outdoor play'']]The child in the case study part 1 becomes frustrated when the rules of the game change. This immediate emotional response is different from a longer-term pattern of emotional dysregulation or internalising symptoms. When research findings are compared, it is important to consider which aspect of emotional well-being is measured.

== '''How does outdoor play influence children's emotional well-being?''' ==
Outdoor play may be related to children's emotional well-being through emotional, cognitive, and social processes. Possible pathways discussed in the recent research include [[Emotional regulation|emotion regulation]], working memory, social interaction, physical activity, connection with the nature and adventurous play. However, these pathways have not all been directly tested as mechanisms, and many of the outdoor play literatures remain observational (Dodd et al., 2026; de Lannoy et al.,2023). Psychological theory can help to explain how and why outdoor play experiences may influence children's emotional well-being. Although the evidence does not yet show that psychological processes cause the relationship between outdoor play and children's emotional well-being.
=== '''Emotion regulation''' ===
Emotion regulation provides a psychological framework for understanding how children may manage emotional situations during outdoor play. Gross (2025) described emotional regulation as a process involving identification, selection and implementation. Identification concerns deciding whether to regulate an emotion, selection concerns selecting regulation strategy and implementation concerns applying chosen response into practice. Gross (2015) also described situation selection, situation modification, attention deployment cognitive change and response modulation. During outdoor play, children may experience frustration, conflict, disagreement, uncertainty or changes to their activity. Gross framework can be applied to these situations to consider how a children recognise an emotional response, choose strategies to manage and act on chosen strategies. However, Gross (2015) did not examine outdoor play, so applying the framework does not show that outdoor play improves children's emotion regulation.
{| class="wikitable"
| valign="top" |'''Case study: Part 3'''[[File:14Y Ncdc july 5th-802.jpg|thumb|202x202px|'''Figure 4'''. ''Children can respond differently to situations that occur during outdoor play.'']]When the rule of game change, the child becomes frustrated and decided to step away. After a short time the child returns and suggests for different way to continue the game (see Figure 4). Suggesting a change to the game can be considered an example of situation modification. This shows how Gross's emotion regulation framework can be applied to an emotional situation during outdoor play.

=== '''Working memory and cognitive process''' ===
Working memory can be one cognitive process involved in the association between outdoor play and emotional dysregulation. Lee et al., (2025) examined 325 preschool children and tested working memory as a statistical mediator. Outdoor play was examined across three periods of the day; wake up to noon, noon to 6 pm, and 6 pm to bedtime. The findings differed according to the timing of outdoor play. More outdoor play between noon and 6 pm was associated with lower emotional dysregulation. In contrast, more outdoor play before noon and 6 pm was associated with higher emotional dysfunction. Afternoon outdoor play was also associated with better working memory, and better working memory was associated with lower emotional dysregulation.
When working memory was included in the analysis, the association between afternoon outdoor play and emotional dysregulation was no longer statistically significant. Lee et al., (2025) reported this as full mediation. This suggests working memory may be involved in the association between afternoon play and lower emotional dysregulation. However, the study was observational, so the mediation analysis does not show that outdoor play caused better working memory or lower emotional dysregulation.
== '''Social and environmental influences on outdoor play''' ==
* Outdoor play opportunities are shaped by more than the physical being outdoor space. Beekhuizen et al. (2025) interviewed 40 children aged 6 to 12, with and without disabilities about facilitators and barriers to inclusive outdoor play. The findings were identified personal factor, interacting factors and environmental factors.
* Personal factors included experiencing [[w:Autonomy|autonomy]], and children's feelings of physical and social limitations. Interacting factors included making contact, growing up together, and adopting the ways of playing. Environmental factors included parents, outdoor play environments, communities, and time constrains (Beekhuizen et al., 2025).
* Opportunities for outdoor play was not experienced in the same way by all children. Beekhuizen et al. (2025) found that children with disabilities experienced more barriers than children with no disability. The challenges were related to making contact with other children, adopting play and the physical play environment.
* Ferguson et al. (2025) examined the association between outdoor play and children's social-emotional competence. In a cross sectional analysis of 2568 children, aged 7.1 to 12.6 years from multi-ethnic urban cohort found that outdoor play was associated with better social-emotional competence. However, the association was differed across ethnicity, and weekday or weekend outdoor play.
* Ferguson et al. (2025) also examined area deprivation. The relation between outdoor play and social-emotional competence appeared stronger in less deprived area, although the statistical evidence for the differences by deprivation was significantly weak.
=== '''Social relationship and inclusion''' ===
* Beekhuizen et al. (2025) identified making contact and growing up together as interacting factors in inclusive outdoor play. Some children described familiarity with other children as an easy way to approach, communication and play together. Making contact could also be a barrier when children approaching to another unfamiliar children or joining in play who were already playing.
* Children also described the need to adopt games so that children with different abilities could participate. School and communities were identified settings where children with and without disabilities could become familiar with each other (Beekhuizen et al., 2025).
* In the recent observational research by Beekhuizen et al. (2026) observed outdoor play among children with and without disability. The researchers found that getting to know each other, making contact and interaction while playing together as process of inclusive outdoor play. These observational findings showed that familiarity and making contact determine social and inclusive play because children chose to play with children they already knew.
* Ferguson et al. (2025) also found that the association between outdoor play and social emotional competence was not the same across all ethnic and deprivation groups. In the cross sectional analysis of 2568 children aged 7.1 to 12.6 years from multi ethnic urban cohort, outdoor play was associated with better social-emotional competence. However, associations varies across same ethnic groups and according to weekday or weekend outdoor play.
=== '''Autonomy, parents and time''' ===
* Experiencing autonomy was identified as a personal factor in inclusive outdoor play. Children having some independence during outdoor play could promote their sense of independence over what they do and who they play with (Beekhuizen et al., 2025).
* Experiencing autonomy also included opportunities to play without direct involvement of parents. Some children with disabilities described wanting to play outside independently, although parental support could make outdoor play possible (Beekhuizen et al., 2025)
* Parents were identified as an environmental factors. Beekhuizen et al. (2025) found that parental involvement could support children's participation in outdoor play, specially when child needed help to access or participate in outdoor play.
* Time constraints were considered as another environmental factor. Some children with disabilities were described as having limited outdoor play time due to parents work schedule, after-school arrangements or longer travel distance between home and school (Beekhuizen et al., 2025)
=== '''Outdoor environments and accessibility''' ===
* The outdoor play environment was identified as an environmental factor that could could support or restrict inclusive outdoor play. Children described both physical and social aspects of outdoor play environments. For example, children discussed the importance of physical and social safety, including traffic near playgrounds and disputes among children. Accessibility was particularly relevant to children with disabilities because opportunities for inclusive outdoor play could be affected by play environments and physical abilities (Beekhuizen et al., 2025).
* Pereira et al. (2024) provided evidence about the physical features of outdoor play spaces. Their systematic review included 51 articles representing 45 primary studies aged between 5 to 12 and examined particular environmental features like fixed structures, natural elements, floor marking, loose parts or equipment and available play area.
* Pereira et al. (2024) found positive association between outdoor play space features and children's behaviours. However, there was substantial variation between studies so the review could not establish clear conclusions about the effects of particular environmental features.

|Key points
* Beekhuizen et al. (2025) identified personal, interacting and environmental factors that could facilitate or restrict inclusive outdoor play.
* Social relationships and familiarity affected participation, with children with disabilities reporting more barriers to inclusive outdoor play (Beekhuizen et al., 2025).
* Associations between outdoor play and social-emotional competence varied across some population groups and play contexts (Ferguson et al., 2025).
|}
== '''What does recent research show about outdoor play and children's emotional well-being?''' ==
* Recent research has examined various aspects of outdoor play and children's emotional well-being and provides mixed evidence. These include emotional dysregulation (Lee et al., 2025), social-emotional competence (Ferguson et al., 2025), positive and negative affect (Poulos et al., 2026), and internalising and externalising symptoms (Dodd et al., 2026).
* Ferguson et al. (2025) found that more frequent outdoor play was associated with better social-emotional competence. However, the associations varied across some ethnic groups and according to whether outdoor play occurred on school days or weekends.
* Dodd et al. (2026) provides longitudinal evidence from 4,151 children from the Growing Up in Scotland study. Children who played outdoors more frequently between approximately 2 and 4 years of age were more likely to follow a trajectory of low and stable internalising and externalising symptoms through to age 8.
* Poulos et al. (2026) examined children's emotional state immediately after recess during hot weather. Among 317 children in years 4 and 5, the positive effect was higher after outdoor recess and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Together, these studies show evidence of associations between outdoor play or outdoor recess and several aspects of emotional well-being. However, the studies did not show the common effect because the study differ in children's ages, research designs, measures of outdoor play, and emotional outcomes.
=== '''Consistency of recent research findings''' ===
* Recent findings do not show the same effect across all outcomes. Ferguson et al. (2025) found that more frequent outdoor play was associated with lower total difficulties and greater prosocial behaviour. In contrast, Davenport et al. (2024) found that most associations between outdoor play and the physical, cognitive and social-emotional developmental indicators examined were not statistically significant. Therefore, the recent studies have not found significant association across all developmental outcomes.
* Findings can also differ according to the emotional outcome being measured. Poulos et al. (2026) found higher positive affect after outdoor and gymnasium recess than after classroom recess, but no significant differences in negative affect between the three recess settings. Lee et al. (2025) found that lower emotional dysregulation associated with greater afternoon outdoor play but higher emotional dysregulation is associated with greater outdoor play earlier and later in the day.
* Dodd et al. (2026) provides longer-term evidence. More frequent outdoor play during the preschool years predicted lower odds of belonging to the increasing or decreasing internalising and externalising symptom trajectory groups, relative to the normative low and stable group. This shows an association between early outdoor play and mental-health symptom trajectories across childhood rather than an emotional outcome measured at one point in time.
* Associations may also vary across children and outdoor play contexts. Ferguson et al. (2025) reported differences according to ethnicity and whether outdoor play occurred on school days or weekends.
* Recent findings suggest that associations between outdoor play and emotional well-being are not the same across all outcomes, children and play contexts. The studies differ in children's age, research designs, measures of outdoor play, and emotional outcomes. Thus, findings should not be treated as evidence of one single effect.
=== '''Strengths and limitations of current research''' ===
* Longitudinal research strengthens the evidence concerning temporal relationship. Dodd et al. (2026) analysed 4,151 children from the Growing Up in Scotland study. Outdoor play was measured at approximately 2, 3 and 4 years of age, while internalising and externalising symptoms were measured at approximately 4, 5, 6 and 8 years. This allowed the researchers to examine whether early outdoor play predicted different mental-health symptom trajectories across childhood.
* Although, longitudinal evidence does not establish cause and effect. Dodd et al. (2026) identified reliance on parent report measures as a key limitation, while Lee et al. (2025) also discussed about the possibility of reverse causation when interpreting associations between the timing of outdoor play and emotional dysregulation.
* Measurement of outdoor play is another important consideration. Davenport et al. (2024) examined both parent reported and device measured outdoor play and also tested whether associations were independent of outdoor moderate to vigorous physical activity. This approach distinguishes outdoor play from outdoor physical activity rather than interchangeable measures.
* Limitations are also present across the wider outdoor play literature. De Lannoy et al. (2023) identified 275 Canadian outdoor play publications and found that cross sectional study design was most common. Mental and emotional development had received less research attention in comparison to physical health and development.

|}
As shown in table 2, the recent evidence has different methodological strengths and limitations. Longitudinal data provide stronger evidence about temporal ordering than cross-sectional studies, while the use of parent-reported and device-measured outdoor play addresses some measurement concerns. However, much of the evidence remains observational, several studies rely on parent-reported measures, and differences in emotional outcomes and play contexts limit the direct comparison between studies.
{| class="wikitable"
|Key points
* Recent studies report positive, mixed and non-significant findings across different emotional outcomes and measures of outdoor play (Davenport et al., 2024; Ferguson et al., 2025).
* Lee et al. (2025) and Dodd et al. (2026) found associations across different emotional outcomes and time frames, from emotional dysregulation to later symptom trajectories.
* Differences in study design, measurement, children's age and play context mean the findings should not be interpreted as one consistent effect of outdoor play on emotional well-being.
|}
== '''How do families, communities and schools support outdoor play opportunities?''' ==
* Opportunities for outdoor play are influenced by children's social and physical environments. Beekhuizen et al. (2025) identified parents, outdoor play environments, communities and time constraints as environmental factors that could act as facilitators or barriers to inclusive outdoor play.
* Support for outdoor play also involves whether children can participate with other children. Beekhuizen et al. (2025) identified experiencing autonomy, growing up together, making contact and adapting ways of playing as factors involved in inclusive outdoor play.
* The 2025 Position Statement on Active Outdoor Play recommends increasing opportunities for active outdoor play in settings where people live, learn, work and play. It also emphasises collaboration across sectors, settings and societies to support equitable access to active outdoor play (Lee et al., 2025).
=== '''Families''' ===
* Beekhuizen et al. (2025) identified parents as an environmental factor in inclusive outdoor play. Children with disabilities described parents as important in encouraging participation and, for some children, helping to explain their disability to other children.
* Experiencing autonomy was identified as an important personal factor. Some children with disabilities wanted their parents to allow them freedom during outdoor play. Some preferred their parents not to accompany them to the playground, while others were comfortable with parents remaining at a reasonable distance (Beekhuizen et al., 2025).
* These findings indicate that parental support and children's autonomy can both be relevant to opportunities for outdoor play. For some children with disabilities, support could be necessary for participation while opportunities to play more independently were also valued (Beekhuizen et al., 2025).
* Beekhuizen et al. (2025) identified parental support as important for facilitating positive inclusive play experiences. The authors also recommended providing children and parents with knowledge about disabilities and possible adaptations that can support participation
* Family level opportunities also need to be interpreted alongside the time constraints. Some children attending special education described long journeys between school and home that reduced the time available for outdoor play (Beekhuizen et al., 2025). This means that opportunities for outdoor play cannot be interpreted only in terms of children's or parents' preferences.
=== '''Communities''' ===
* Beekhuizen et al. (2025) identified communities and the outdoor play environment as environmental factors in inclusive outdoor play. Children described physically and socially safe playgrounds as important. While barriers included structure of playgrounds that made participation difficult for some children with disabilities.
* The social environment of a community was also important. Children with disabilities described smaller communities, such as villages and schools, the places where other children and parents could become more familiar with disability. This familiarity was associated with greater acceptance and stronger connections with other children (Beekhuizen et al., 2025).
* Recent observational research also shows that physical access alone does not explain inclusive outdoor play. Beekhuizen et al. (2026) observed 63 children with and without disabilities during six inclusive outdoor play sessions and assessed both children's playfulness and environmental supportiveness. Children with disabilities showed significantly lower playfulness scores indicating that opportunities for inclusive play were not experienced equally.
* The 2025 Position Statement on Active Outdoor Play recommends collaboration across sectors, settings and societies to preserve, promote and value equitable access to active outdoor play. This places responsibility for outdoor play opportunities across communities and wider systems rather than on children and families alone (Lee et al., 2025).
=== '''Schools''' ===
* Schools can provide opportunities for children with and without disabilities to become familiar with one another. Beekhuizen et al. (2025) identified growing up together and making contact as interacting factors in inclusive outdoor play. Children described familiarity with other children as making contact easier.
* School circumstances can also affect the time and opportunities available for outdoor play. Some children attending special primary education described long travel times between school and home as reducing the time available to play outdoors. Beekhuizen et al. (2025) identified these experiences under time constraints.
* Recess provides another school setting in which children's emotional experiences have been examined. Poulos et al. (2026) studied 317 Year 4 and 5 children during extreme heat weather and found significantly higher positive affect after outdoor and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Poulos et al. (2026) identified implications for school health, policy and equity, including the need for heat adaptive infrastructure to support access to recess environments during extreme heat. However, the findings do not show that outdoor recess is always better than indoor recess because positive affect was also higher following gymnasium recess.

Two primary school aged children A and B enjoy playing outdoors. They both lived near the same playground. Child A was very familiar with the playground and knows several other children who play there and easily join the games. While child B has disability, uses mobility device and does not know other children at playground. Some parts of the playground are difficult to access and joining other children who are already playing can also be challenging. Child B's parents can provide support, although the child also prefers to play more independently.

'''''<u>Note: Answers to the quiz is 1: True and 2 False</u>'''''
== '''Conclusion''' ==
* Outdoor play and children's emotional well-being are measured in different ways across recent research. Outdoor play is not equivalent to outdoor physical activity, while emotional outcomes include emotional dysregulation, social-emotional competence, positive and negative affect, and internalising and externalising symptoms. These differences need to be considered when findings across studies are compared.
* Research also provides mixed evidence about how outdoor play may be related to emotional well-being. Gross's (2015) emotion-regulation framework can be applied to emotional situations experienced during play, but it does not show that outdoor play improves emotion regulation. Lee et al. (2025) provides more direct evidence of a possible cognitive process, with working memory statistically mediating the association between afternoon outdoor play and lower emotional dysregulation. However, this observational finding does not establish causation.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.
* Overall, current research supports an association between outdoor play and some aspects of children's emotional well-being but does not establish one consistent effect. Differences in measurement, research design, children and play contexts remain important when interpreting the evidence.

[[File:School children happily playing in playground.jpg|thumb|'''Figure 1'''. Children engaged in outdoor play.]]
|'''Case study: Part 1'''
A child arrives at playground and joins a group of children who are already playing. The children are making their own game and deciding the rules as they play. At first, child enjoys choosing where and what to play and moving between the different activities. During the game, another child changes the rules of the game and argument breaks out. The child becomes frustrated and avoids the activity. After watching for short time, the child returns, suggests for new idea to continue game and re-joins the group. How might experiences like this during outdoor play influence children's emotional well-being? Emotional regulation theory provides one way of understanding on how children may respond to emotional situations during play (see figure 1) (Gross, 2015).
|}
Outdoor play can involve more than physical movements. It is more than simply being outside and engage in the activities across playgrounds, gardens, streets and natural spaces. Outdoor play involves exploration, social interaction, choice and challenge and engagement with surrounding environment (Dodd et al.,2026; Pereira et al.,2024). These experiences may create emotional situations in which children need to respond to frustration, disagreement, uncertainty or excitement. Gross (2015) [[emotional regulation]] theory provides a [[psychological]] explanation for how children may recognise and respond to these emotional situations. Outdoor play experiences are also shaped by the environment where play takes place. Experiences are shaped by the different opportunities provided by different physical and social environments, which means the same outdoor space may not provide the same experience for every child (Morgenthaler et al.,2024).This chapter examines how [[Emotional regulation|emotional,]] [[Cognitive psychology|cognitive]], social and environmental processes may help explain the relationship between outdoor play and children's emotional well-being.

== '''Understanding outdoor play and children's emotional well-being''' ==
[[File:Water-outdoor-people-girl-play-boy-938233.jpg|thumb|'''Figure 2'''. ''Visualise outdoor play as providing children with opportunities to explore, make choices, interact with others and respond to changing situations through activities such as water play.''|265x265px]]
Outdoor play and children's emotional well-being are not measured as single and consistent concepts across recent research. Outdoor play may be examined as voluntary and intrinsically motivated activity, self directed play, parent reported outdoor play, or device-measured outdoor play activity. It should also be distinguished from outdoor moderate to vigorous physical activity because these measures do not represent the same behaviour (Davenport et al., 2025). Children's emotional well-being is also examined through different outcomes, that includes [[emotional regulation]], social-emotional competence, positive and negative affect, and internalising or externalising symptoms. These differences are significant because outdoor play and emotional well-being are not measured as single, consistent constructs across research.
=== Outdoor play ===
Outdoor play is voluntary and and intrinsically motivated activity that occurs in outdoor environments like gardens, playgrounds, parks and natural spaces (Dodd et al., 2026). Free play can be also self-directed, which means children to freely interact with the environment and have autonomy to make choices about their activities (Biino et al., 2025). Outdoor play should not be treated as same as outdoor physical activity. Davenport et al., (2025) examined outdoor play separately from outdoor moderate- to- vigorous physical activity (MVPA). This distinction is significant because research on children's outdoor play is not necessarily measuring the same behaviour as research on the intensity of physical activity.
=== Children's emotional well-being ===
Children's emotional well-being is not represented by single common outcome across recent outdoor play research. Emotional dysregulation has been examined in relation to the amount and timing of outdoor play (Lee et al., 2025), while social-emotional competence includes difficulties and [[Prosocial behavior/Keywords/Definitions|prosocial behaviour]] (Ferguson et al., 2025). Other studies have examined positive and negative affect following recess (Poulos et al., 2026) and trajectories of internalising and externalising symptoms across childhood (Dodd et al., 2026). These outcomes represent different aspects and timeframes of emotional functioning, so they should not be treated as equivalent when findings are compared.

As shown in Table 1, the studies do not measure the same aspect or time frame of children's emotional functioning. Affect immediately following recess should not be treated as equivalent to emotional dysregulation measured over time or trajectories of internalising and externalising symptoms across childhood. This difference need to be considered when examining whether outdoor play is associated with children's emotional well-being.

''What is being measured?''
{| class="wikitable"
| valign="top" |[[File:Children marbles.jpg|thumb|177x177px|'''Figure 3'''. ''Children may experience different emotional responses during social outdoor play'']]The child in the case study part 1 becomes frustrated when the rules of the game change. This immediate emotional response is different from a longer-term pattern of emotional dysregulation or internalising symptoms. When research findings are compared, it is important to consider which aspect of emotional well-being is measured.

== '''How does outdoor play influence children's emotional well-being?''' ==
Outdoor play may be related to children's emotional well-being through emotional, cognitive, and social processes. Possible pathways discussed in the recent research include [[Emotional regulation|emotion regulation]], working memory, social interaction, physical activity, connection with the nature and adventurous play. However, these pathways have not all been directly tested as mechanisms, and many of the outdoor play literatures remain observational (Dodd et al., 2026; de Lannoy et al.,2023). Psychological theory can help to explain how and why outdoor play experiences may influence children's emotional well-being. Although the evidence does not yet show that psychological processes cause the relationship between outdoor play and children's emotional well-being.
=== '''Emotion regulation''' ===
Emotion regulation provides a psychological framework for understanding how children may manage emotional situations during outdoor play. Gross (2025) described emotional regulation as a process involving identification, selection and implementation. Identification concerns deciding whether to regulate an emotion, selection concerns selecting regulation strategy and implementation concerns applying chosen response into practice. Gross (2015) also described situation selection, situation modification, attention deployment cognitive change and response modulation. During outdoor play, children may experience frustration, conflict, disagreement, uncertainty or changes to their activity. Gross framework can be applied to these situations to consider how a children recognise an emotional response, choose strategies to manage and act on chosen strategies. However, Gross (2015) did not examine outdoor play, so applying the framework does not show that outdoor play improves children's emotion regulation.
{| class="wikitable"
| valign="top" |'''Case study: Part 3'''[[File:14Y Ncdc july 5th-802.jpg|thumb|202x202px|'''Figure 4'''. ''Children can respond differently to situations that occur during outdoor play.'']]When the rule of game change, the child becomes frustrated and decided to step away. After a short time the child returns and suggests for different way to continue the game (see Figure 4). Suggesting a change to the game can be considered an example of situation modification. This shows how Gross's emotion regulation framework can be applied to an emotional situation during outdoor play.

=== '''Working memory and cognitive process''' ===
Working memory can be one cognitive process involved in the association between outdoor play and emotional dysregulation. Lee et al., (2025) examined 325 preschool children and tested working memory as a statistical mediator. Outdoor play was examined across three periods of the day; wake up to noon, noon to 6 pm, and 6 pm to bedtime. The findings differed according to the timing of outdoor play. More outdoor play between noon and 6 pm was associated with lower emotional dysregulation. In contrast, more outdoor play before noon and 6 pm was associated with higher emotional dysfunction. Afternoon outdoor play was also associated with better working memory, and better working memory was associated with lower emotional dysregulation.
When working memory was included in the analysis, the association between afternoon outdoor play and emotional dysregulation was no longer statistically significant. Lee et al., (2025) reported this as full mediation. This suggests working memory may be involved in the association between afternoon play and lower emotional dysregulation. However, the study was observational, so the mediation analysis does not show that outdoor play caused better working memory or lower emotional dysregulation.
== '''Social and environmental influences on outdoor play''' ==
* Outdoor play opportunities are shaped by more than the physical being outdoor space. Beekhuizen et al. (2025) interviewed 40 children aged 6 to 12, with and without disabilities about facilitators and barriers to inclusive outdoor play. The findings were identified personal factor, interacting factors and environmental factors.
* Personal factors included experiencing [[w:Autonomy|autonomy]], and children's feelings of physical and social limitations. Interacting factors included making contact, growing up together, and adopting the ways of playing. Environmental factors included parents, outdoor play environments, communities, and time constrains (Beekhuizen et al., 2025).
* Opportunities for outdoor play was not experienced in the same way by all children. Beekhuizen et al. (2025) found that children with disabilities experienced more barriers than children with no disability. The challenges were related to making contact with other children, adopting play and the physical play environment.
* Ferguson et al. (2025) examined the association between outdoor play and children's social-emotional competence. In a cross sectional analysis of 2568 children, aged 7.1 to 12.6 years from multi-ethnic urban cohort found that outdoor play was associated with better social-emotional competence. However, the association was differed across ethnicity, and weekday or weekend outdoor play.
* Ferguson et al. (2025) also examined area deprivation. The relation between outdoor play and social-emotional competence appeared stronger in less deprived area, although the statistical evidence for the differences by deprivation was significantly weak.
=== '''Social relationship and inclusion''' ===
* Beekhuizen et al. (2025) identified making contact and growing up together as interacting factors in inclusive outdoor play. Some children described familiarity with other children as an easy way to approach, communication and play together. Making contact could also be a barrier when children approaching to another unfamiliar children or joining in play who were already playing.
* Children also described the need to adopt games so that children with different abilities could participate. School and communities were identified settings where children with and without disabilities could become familiar with each other (Beekhuizen et al., 2025).
* In the recent observational research by Beekhuizen et al. (2026) observed outdoor play among children with and without disability. The researchers found that getting to know each other, making contact and interaction while playing together as process of inclusive outdoor play. These observational findings showed that familiarity and making contact determine social and inclusive play because children chose to play with children they already knew.
* Ferguson et al. (2025) also found that the association between outdoor play and social emotional competence was not the same across all ethnic and deprivation groups. In the cross sectional analysis of 2568 children aged 7.1 to 12.6 years from multi ethnic urban cohort, outdoor play was associated with better social-emotional competence. However, associations varies across same ethnic groups and according to weekday or weekend outdoor play.
=== '''Autonomy, parents and time''' ===
* Experiencing autonomy was identified as a personal factor in inclusive outdoor play. Children having some independence during outdoor play could promote their sense of independence over what they do and who they play with (Beekhuizen et al., 2025).
* Experiencing autonomy also included opportunities to play without direct involvement of parents. Some children with disabilities described wanting to play outside independently, although parental support could make outdoor play possible (Beekhuizen et al., 2025)
* Parents were identified as an environmental factors. Beekhuizen et al. (2025) found that parental involvement could support children's participation in outdoor play, specially when child needed help to access or participate in outdoor play.
* Time constraints were considered as another environmental factor. Some children with disabilities were described as having limited outdoor play time due to parents work schedule, after-school arrangements or longer travel distance between home and school (Beekhuizen et al., 2025)
=== '''Outdoor environments and accessibility''' ===
* The outdoor play environment was identified as an environmental factor that could could support or restrict inclusive outdoor play. Children described both physical and social aspects of outdoor play environments. For example, children discussed the importance of physical and social safety, including traffic near playgrounds and disputes among children. Accessibility was particularly relevant to children with disabilities because opportunities for inclusive outdoor play could be affected by play environments and physical abilities (Beekhuizen et al., 2025).
* Pereira et al. (2024) provided evidence about the physical features of outdoor play spaces. Their systematic review included 51 articles representing 45 primary studies aged between 5 to 12 and examined particular environmental features like fixed structures, natural elements, floor marking, loose parts or equipment and available play area.
* Pereira et al. (2024) found positive association between outdoor play space features and children's behaviours. However, there was substantial variation between studies so the review could not establish clear conclusions about the effects of particular environmental features.

|Key points
* Beekhuizen et al. (2025) identified personal, interacting and environmental factors that could facilitate or restrict inclusive outdoor play.
* Social relationships and familiarity affected participation, with children with disabilities reporting more barriers to inclusive outdoor play (Beekhuizen et al., 2025).
* Associations between outdoor play and social-emotional competence varied across some population groups and play contexts (Ferguson et al., 2025).

== '''What does recent research show about outdoor play and children's emotional well-being?''' ==
* Recent research has examined various aspects of outdoor play and children's emotional well-being and provides mixed evidence. These include emotional dysregulation (Lee et al., 2025), social-emotional competence (Ferguson et al., 2025), positive and negative affect (Poulos et al., 2026), and internalising and externalising symptoms (Dodd et al., 2026).
* Ferguson et al. (2025) found that more frequent outdoor play was associated with better social-emotional competence. However, the associations varied across some ethnic groups and according to whether outdoor play occurred on school days or weekends.
* Dodd et al. (2026) provides longitudinal evidence from 4,151 children from the Growing Up in Scotland study. Children who played outdoors more frequently between approximately 2 and 4 years of age were more likely to follow a trajectory of low and stable internalising and externalising symptoms through to age 8.
* Poulos et al. (2026) examined children's emotional state immediately after recess during hot weather. Among 317 children in years 4 and 5, the positive effect was higher after outdoor recess and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Together, these studies show evidence of associations between outdoor play or outdoor recess and several aspects of emotional well-being. However, the studies did not show the common effect because the study differ in children's ages, research designs, measures of outdoor play, and emotional outcomes.
=== '''Consistency of recent research findings''' ===
* Recent findings do not show the same effect across all outcomes. Ferguson et al. (2025) found that more frequent outdoor play was associated with lower total difficulties and greater prosocial behaviour. In contrast, Davenport et al. (2024) found that most associations between outdoor play and the physical, cognitive and social-emotional developmental indicators examined were not statistically significant. Therefore, the recent studies have not found significant association across all developmental outcomes.
* Findings can also differ according to the emotional outcome being measured. Poulos et al. (2026) found higher positive affect after outdoor and gymnasium recess than after classroom recess, but no significant differences in negative affect between the three recess settings. Lee et al. (2025) found that lower emotional dysregulation associated with greater afternoon outdoor play but higher emotional dysregulation is associated with greater outdoor play earlier and later in the day.
* Dodd et al. (2026) provides longer-term evidence. More frequent outdoor play during the preschool years predicted lower odds of belonging to the increasing or decreasing internalising and externalising symptom trajectory groups, relative to the normative low and stable group. This shows an association between early outdoor play and mental-health symptom trajectories across childhood rather than an emotional outcome measured at one point in time.
* Associations may also vary across children and outdoor play contexts. Ferguson et al. (2025) reported differences according to ethnicity and whether outdoor play occurred on school days or weekends.
* Recent findings suggest that associations between outdoor play and emotional well-being are not the same across all outcomes, children and play contexts. The studies differ in children's age, research designs, measures of outdoor play, and emotional outcomes. Thus, findings should not be treated as evidence of one single effect.
=== '''Strengths and limitations of current research''' ===
* Longitudinal research strengthens the evidence concerning temporal relationship. Dodd et al. (2026) analysed 4,151 children from the Growing Up in Scotland study. Outdoor play was measured at approximately 2, 3 and 4 years of age, while internalising and externalising symptoms were measured at approximately 4, 5, 6 and 8 years. This allowed the researchers to examine whether early outdoor play predicted different mental-health symptom trajectories across childhood.
* Although, longitudinal evidence does not establish cause and effect. Dodd et al. (2026) identified reliance on parent report measures as a key limitation, while Lee et al. (2025) also discussed about the possibility of reverse causation when interpreting associations between the timing of outdoor play and emotional dysregulation.
* Measurement of outdoor play is another important consideration. Davenport et al. (2024) examined both parent reported and device measured outdoor play and also tested whether associations were independent of outdoor moderate to vigorous physical activity. This approach distinguishes outdoor play from outdoor physical activity rather than interchangeable measures.
* Limitations are also present across the wider outdoor play literature. De Lannoy et al. (2023) identified 275 Canadian outdoor play publications and found that cross sectional study design was most common. Mental and emotional development had received less research attention in comparison to physical health and development.

|}
As shown in table 2, the recent evidence has different methodological strengths and limitations. Longitudinal data provide stronger evidence about temporal ordering than cross-sectional studies, while the use of parent-reported and device-measured outdoor play addresses some measurement concerns. However, much of the evidence remains observational, several studies rely on parent-reported measures, and differences in emotional outcomes and play contexts limit the direct comparison between studies.
{| class="wikitable"
|Key points
* Recent studies report positive, mixed and non-significant findings across different emotional outcomes and measures of outdoor play (Davenport et al., 2024; Ferguson et al., 2025).
* Lee et al. (2025) and Dodd et al. (2026) found associations across different emotional outcomes and time frames, from emotional dysregulation to later symptom trajectories.
* Differences in study design, measurement, children's age and play context mean the findings should not be interpreted as one consistent effect of outdoor play on emotional well-being.
|}
== '''How do families, communities and schools support outdoor play opportunities?''' ==
* Opportunities for outdoor play are influenced by children's social and physical environments. Beekhuizen et al. (2025) identified parents, outdoor play environments, communities and time constraints as environmental factors that could act as facilitators or barriers to inclusive outdoor play.
* Support for outdoor play also involves whether children can participate with other children. Beekhuizen et al. (2025) identified experiencing autonomy, growing up together, making contact and adapting ways of playing as factors involved in inclusive outdoor play.
* The 2025 Position Statement on Active Outdoor Play recommends increasing opportunities for active outdoor play in settings where people live, learn, work and play. It also emphasises collaboration across sectors, settings and societies to support equitable access to active outdoor play (Lee et al., 2025).
=== '''Families''' ===
* Beekhuizen et al. (2025) identified parents as an environmental factor in inclusive outdoor play. Children with disabilities described parents as important in encouraging participation and, for some children, helping to explain their disability to other children.
* Experiencing autonomy was identified as an important personal factor. Some children with disabilities wanted their parents to allow them freedom during outdoor play. Some preferred their parents not to accompany them to the playground, while others were comfortable with parents remaining at a reasonable distance (Beekhuizen et al., 2025).
* These findings indicate that parental support and children's autonomy can both be relevant to opportunities for outdoor play. For some children with disabilities, support could be necessary for participation while opportunities to play more independently were also valued (Beekhuizen et al., 2025).
* Beekhuizen et al. (2025) identified parental support as important for facilitating positive inclusive play experiences. The authors also recommended providing children and parents with knowledge about disabilities and possible adaptations that can support participation
* Family level opportunities also need to be interpreted alongside the time constraints. Some children attending special education described long journeys between school and home that reduced the time available for outdoor play (Beekhuizen et al., 2025). This means that opportunities for outdoor play cannot be interpreted only in terms of children's or parents' preferences.
=== '''Communities''' ===
* Beekhuizen et al. (2025) identified communities and the outdoor play environment as environmental factors in inclusive outdoor play. Children described physically and socially safe playgrounds as important. While barriers included structure of playgrounds that made participation difficult for some children with disabilities.
* The social environment of a community was also important. Children with disabilities described smaller communities, such as villages and schools, the places where other children and parents could become more familiar with disability. This familiarity was associated with greater acceptance and stronger connections with other children (Beekhuizen et al., 2025).
* Recent observational research also shows that physical access alone does not explain inclusive outdoor play. Beekhuizen et al. (2026) observed 63 children with and without disabilities during six inclusive outdoor play sessions and assessed both children's playfulness and environmental supportiveness. Children with disabilities showed significantly lower playfulness scores indicating that opportunities for inclusive play were not experienced equally.
* The 2025 Position Statement on Active Outdoor Play recommends collaboration across sectors, settings and societies to preserve, promote and value equitable access to active outdoor play. This places responsibility for outdoor play opportunities across communities and wider systems rather than on children and families alone (Lee et al., 2025).
=== '''Schools''' ===
* Schools can provide opportunities for children with and without disabilities to become familiar with one another. Beekhuizen et al. (2025) identified growing up together and making contact as interacting factors in inclusive outdoor play. Children described familiarity with other children as making contact easier.
* School circumstances can also affect the time and opportunities available for outdoor play. Some children attending special primary education described long travel times between school and home as reducing the time available to play outdoors. Beekhuizen et al. (2025) identified these experiences under time constraints.
* Recess provides another school setting in which children's emotional experiences have been examined. Poulos et al. (2026) studied 317 Year 4 and 5 children during extreme heat weather and found significantly higher positive affect after outdoor and gymnasium recess than after classroom recess. There were no significant differences in negative affect between the three recess settings.
* Poulos et al. (2026) identified implications for school health, policy and equity, including the need for heat adaptive infrastructure to support access to recess environments during extreme heat. However, the findings do not show that outdoor recess is always better than indoor recess because positive affect was also higher following gymnasium recess.

Two primary school aged children A and B enjoy playing outdoors. They both lived near the same playground. Child A was very familiar with the playground and knows several other children who play there and easily join the games. While child B has disability, uses mobility device and does not know other children at playground. Some parts of the playground are difficult to access and joining other children who are already playing can also be challenging. Child B's parents can provide support, although the child also prefers to play more independently.

'''''<u>Note: Answers to the quiz is 1: True and 2 False</u>'''''
== '''Conclusion''' ==
* Outdoor play and children's emotional well-being are measured in different ways across recent research. Outdoor play is not equivalent to outdoor physical activity, while emotional outcomes include emotional dysregulation, social-emotional competence, positive and negative affect, and internalising and externalising symptoms. These differences need to be considered when findings across studies are compared.
* Research also provides mixed evidence about how outdoor play may be related to emotional well-being. Gross's (2015) emotion-regulation framework can be applied to emotional situations experienced during play, but it does not show that outdoor play improves emotion regulation. Lee et al. (2025) provides more direct evidence of a possible cognitive process, with working memory statistically mediating the association between afternoon outdoor play and lower emotional dysregulation. However, this observational finding does not establish causation.
* Recent findings are not consistent across all outcomes or contexts. Ferguson et al. (2025) reported associations with better social-emotional competence, Dodd et al. (2026) found longitudinal associations with internalising and externalising symptom trajectories, and Poulos et al. (2026) found differences in positive but not negative affect following recess. In contrast, most associations examined by Davenport et al. (2024) were not statistically significant.

* Overall, current research supports an association between outdoor play and some aspects of children's emotional well-being but does not establish one consistent effect. Differences in measurement, research design, children and play contexts remain important when interpreting the evidence.

Hey, I am excited to see how this chapter turns out. With the use of social media, homeschooling (and something called unschooling) are becoming more popularised. Here are three sources about homeschooling and unschooling:

=== September 14th ===
Discussed the [https://gitlab.com/cortext/cortext-methods/network-mapping/-/tree/test/init_tests tests implemented by Pierre]. Not all parameter combinations make sense. Good idea of his to generate many tests and keep those that run correctly.
Another take away from Pierre's work: must refactor uses of <code>random</code> to mock during testing before converting to <code>python3</code>.
Started this journal!
What parts of the code not to refactor: get <code>parasite_axes</code> from [https://matplotlib.org/ matplotlib], <code>infomap</code> from [https://mapequation.org/ infomap], leave <code>sankey</code> as is, <code>library</code> is possibly dead code.

== '''Overview:''' ==
<div style="border:1px solid #668cff; border-radius:6px; padding:10px; margin:8px 4px 25px 4px;">
'''“Choosing homeschooling or Traditional Schooling?”'''
Think of it this way: You're one of the parents of 2 Children who attend a local school. Over time, you become worried/concerned that your children's education doesn't reflect the type of learning environment you want for them. After the school days your children express that they are being bullied and are feeling quite a bit of academic pressure. Your partner expresses that your children would learn better with greater flexibility and more individual attention. You sit down together to assess what you both think would be best for your children, and after considering their options, you decide to begin homeschooling. But what is actually motivating their decision?

;Focus questions
{{ic|Use bullet points as shown in [[Motivation and emotion/Tutorials/Wiki editing|Tutorial 2]]}}
# What are the primary push (avoidance) and pull (approach) factors that prompt parents to choose homeschooling over conventional education?
# How do internal value alignments and pedagogical beliefs shape parents' long-term educational goals for their children?
# In what ways do negative school environment experiences (e.g., bullying, unaddressed learning needs) act as acute psychological drivers for school withdrawal?
# How do parental self-efficacy and perceived capability influence whether motivational intentions successfully translate into home education?
# How do initial reactive motivations evolve over time into proactive, sustaining educational practices as families adapt?
</div>
== '''Understanding homeschooling and parental motivation''' ==
* Parental motivation to homeschool represents a dynamic, goal-directed psychological process that governs how families initiate and sustain home-based education (Green & Hoover-Dempsey, 2007).
=== '''Multiple motivations and values''' ===
* Parents rarely choose homeschooling for a single reason; decisions typically reflect a complex combination of academic, social, and emotional factors (Collom, 2005).
* Home education allows parents to integrate their personal, moral, and cultural values directly into their children's daily learning environment (Morton, 2010).
* Increased parent-child interaction acts as a primary motivator, fostering stronger attachment and active participation in developmental milestones (Guterman & Neuman, 2017).

'''Figure 1.''' A young girl focuses on her laptop from a table, during remote lockdown learning.
</div></div>
=== '''External push factors and tailored education''' ===
* Acute negative experiences in conventional settings, such as peer victimization and persistent bullying, push parents to seek protective alternatives (Green & Hoover-Dempsey, 2007).
* Parents are driven by the desire to provide specific pedagogical approaches that conventional schools may fail to deliver (Thomas, 2016).
* Economic factors, such as balancing private school tuition costs against the financial trade-offs of single-income home education, influence decision feasibility (Collom, 2005).
* Disruptions during pandemic lockdowns exposed widespread gaps in institutional remote instruction, driving many families to transition from temporary crisis schooling to permanent, intentional home education (Ray, 2021; see Figure 1).
=== '''Parental role construction and self-efficacy''' ===
* Decision-making begins when parents reconstruct their parental identity to include primary responsibility for formal academic instruction (Ice & Hoover-Dempsey, 2011).
* Grounded in Bandura's (1997) self-efficacy theory, a parent's belief in their ability to teach strongly dictates whether motivational intentions turn into actual behavior.
* As parents gain instructional experience, perceived self-efficacy increases, bolstering long-term commitment to home education (Green & Hoover-Dempsey, 2007).
== '''Parents' values and educational goals''' ==
* Value-driven motivations represent approach-oriented goals where parents proactively seek to align education with their core philosophical ideals (Morton, 2010).
=== '''Educational beliefs and goals''' ===
* '''Pedagogical philosophy:''' Parents hold distinct beliefs about how children learn best, often favoring constructivist or child-led learning over rigid institutional curricula (Thomas, 2016).
* Motivation is driven by fostering deep curiosity and lifelong learning rather than preparing for standardized testing (Ames, 1992).
* Educational goals prioritize emotional resilience, character building, and social-emotional maturity alongside academic achievement (Guterman & Neuman, 2017).
=== '''Individualized education''' ===
* Homeschooling allows parents to adapt instructional speed to match their child's unique cognitive strengths and weaknesses (Thomas, 2016).
* Parents retain freedom to select specialized learning materials that cater to specific talents, neurodivergent needs, or personal interests (Jackson, 2017).
* Eliminating classroom distractions enables more efficient, targeted daily study sessions (Neuman & Aviram, 2003).

Parent guiding children through individualized home learning activities
'''''Figure 1.'' Parental involvement in home education reflects both approach motives (desire for custom pedagogy) and high instructional self-efficacy.'''
</div></div>
=== '''Perceived benefits''' ===
* Spending extended time together strengthens sibling relationships and parent-child relational bonds (Morton, 2010).
* Families gain time sovereignty, allowing them to structure schedule routines around family needs rather than rigid school calendars.
* Parents perceive home environments as safer spaces for children to build self-esteem free from peer pressure and social comparison (Guterman & Neuman, 2017).
== '''Concerns about conventional schooling''' ==
* Avoidance-oriented motivations stem from perceived mismatches between institutional school environments and a child's developmental well-being (Green & Hoover-Dempsey, 2007).
=== '''School-related structural concerns''' ===
* '''Classroom overcrowding''' - High student-to-teacher ratios reduce individualized attention and slow down academic progression for both gifted and struggling students (Thomas, 2016).
* '''Academic pressure''' - Oversaturation of high-stakes assessments is perceived by parents as damaging to intrinsic motivation and creative inquiry (Ames, 1992).
* Inflexible school schedules and rigid administrative policies can create systemic friction for families seeking adaptability.
=== '''Child well-being and experiences''' ===
* Chronic bullying and playground exclusion serve as major emotional catalysts for removing children from school (Green & Hoover-Dempsey, 2007).
* Parents report withdrawing children due to school-induced stress, school refusal behaviors, and burnout (Jackson, 2017).
* Conventional settings often lack resources to support children with ADHD, Autism, or learning differences, leading parents to intervene (Jackson, 2017).
=== '''Perception versus objective circumstances''' ===
* Parental choices are guided by their subjective perception of school climate quality, regardless of objective national standards (Collom, 2005).
* Declining trust in school administration leads parents to rely on their own evaluation of what is best for their child (Ice & Hoover-Dempsey, 2011).
* Specific negative incidents often act as the tipping point that transforms ongoing background dissatisfaction into definitive action (Neuman & Aviram, 2003).
== '''Autonomy, control, and family circumstances''' ==
* Translating motivational desires into sustainable home education requires a combination of personal agency, perceived capability, and structural feasibility (Bandura, 1997).
=== '''Parental autonomy and responsibility''' ===
* Parents seek full sovereignty over curriculum content, moral exposure, and daily instructional methods (Bartholet, 2020).
* Motivation involves stepping into full accountability for the academic and developmental outcomes of the child (Ice & Hoover-Dempsey, 2011).
* Self-Determination Theory suggests that exercising educational autonomy fulfills a core psychological need for parents (Deci & Ryan, 2000).
=== '''Self-efficacy and competence''' ===
* Parents must feel cognitively and pedagogically capable of facilitating grade-appropriate learning (Bandura, 1997).
* Early worries about teaching ability are offset by accessing educational resources and supportive peer networks (Green & Hoover-Dempsey, 2007).
* High self-efficacy enables parents to view teaching challenges as opportunities to learn alongside their children (Ice & Hoover-Dempsey, 2011).
=== '''Family circumstances and practicalities''' ===
* Household budgeting and single-income dynamics significantly shape whether motivational intentions can be realistically sustained (Collom, 2005).
* Remote work options and adaptable work schedules enhance a family's logistical capacity to homeschool.
* Access to local homeschooling co-ops and online communities provides essential emotional and practical scaffolding for parents (Medlin, 2013).
== '''How parental motivations shape homeschooling decisions''' ==
* Parental motivation is an evolving psychological process that adapts as family circumstances, child development, and instructional experience mature (Guterman & Neuman, 2017).
=== '''Approach and avoidance motivational interactions''' ===
* Initial decisions are frequently triggered by avoidance (push) factors (See Table 1), while long-term maintenance relies on approach (pull) factors (Collom, 2005).
* Parents who harbor both strong protective drives and positive educational goals demonstrate the highest commitment levels (Neuman & Aviram, 2003).
* Positive pull factors help buffer against the daily logistical stressors associated with reactive push motivations.
=== '''Motivation, perceived ability, and change over time''' ===
* Over time, initial crisis-driven motivations (e.g., escaping bullying) transition into value-driven practices (e.g., customized interest-based learning) (Neuman & Aviram, 2003).
* As children reach adolescence, parental motives shift toward university preparation, vocational skills, and encouraging autonomous study (Jackson, 2017).
* Increased instructional competence reinforces ongoing motivation, creating a positive self-sustaining cycle (Bandura, 1997).
=== '''Overall psychological explanation''' ===
* Homeschooling decision-making is ultimately explained by the ongoing pursuit of basic psychological need fulfillment—autonomy, competence, and relatedness—for both parent and child (Deci & Ryan, 2000).
* '''Protection vs. flourishing''' - Parental motivation balances protective instincts (avoiding psychological harm) with developmental flourishing (maximizing growth potential) (Guterman & Neuman, 2017).
* Understanding homeschooling requires viewing parents not just as managers of schooling, but as active drivers of a integrated psychological ecosystem (Green & Hoover-Dempsey, 2007).

''Note. Synthesized from empirical literature on parental educational choice and psychological need fulfillment.''
== '''Conclusion''' ==
* Parental motivation to homeschool is not a static decision, but a dynamic psychological process governed by the continuous interplay of push (avoidance) and pull (approach) factors (Collom, 2005; Green & Hoover-Dempsey, 2007).
* Framed through Self-Determination Theory (Deci & Ryan, 2000), home education serves as a vehicle for parents to fulfill fundamental needs for autonomy, instructional competence, and familial relatedness.
* Grounded in Bandura's (1997) social cognitive framework, high parental self-efficacy and active role construction are essential for translating motivational desires into effective, sustained educational practices (Ice & Hoover-Dempsey, 2011).
* While acute environmental stressors (such as bullying, academic anxiety, or neurodivergent mismatches) often act as initial reactive catalysts, long-term commitment relies on proactive, value-driven motivators like tailored pedagogy and family cohesion (Guterman & Neuman, 2017; Neuman & Aviram, 2003).
* Understanding the multifaceted drivers of parental choice provides crucial insights for developmental psychologists, educators, and policymakers seeking to better support family well-being and diverse learning pathways across childhood development (Jackson, 2017; Ray, 2017).

Corrections to earlier documents are recorded in a running correction register (Doc. 190). The documents come with Python verification scripts for recomputing the results.
== Deterministic reading: qubits, measurement, Bell correlations ==
FFGFT translates the qubit formalism completely into a deterministic geometry (Doc. 230). Operationally both descriptions agree up to ξ corrections; they differ in interpretation.
=== State ===
In FFGFT a qubit is a point <math>(z, r, \theta)</math> on a cylinder or torus with <math>z \in [-1,1]</math>, <math>r \in [0,1]</math>, <math>\theta \in [0, 2\pi)</math> and <math>z^2 + r^2 = 1</math>. The bridge to Hilbert space is bijective:
:<math>\alpha = \sqrt{\tfrac{1+z}{2}}\, e^{i\theta/2}, \qquad \beta = \sqrt{\tfrac{1-z}{2}}\, e^{-i\theta/2}</math>
:<math>z = |\alpha|^2 - |\beta|^2, \qquad r = 2|\alpha\beta|, \qquad \theta = \arg\alpha - \arg\beta</math>
In quantum mechanics <math>|\alpha|^2</math> is a probability; in FFGFT <math>r^2 = 1 - z^2</math> is the energy density of the radial configuration.
=== Measurement ===
Measurement is not a probabilistic collapse but a geometric interaction that drives the point <math>(z, r, \theta)</math> deterministically to the nearest pole <math>z = \pm 1</math>. Because the phase <math>\theta</math> is unknown and initial conditions vary minutely, this is statistically indistinguishable from the Born rule:
:<math>P_\text{FFGFT}(z = +1) = \tfrac{1+z}{2} = |\alpha|^2 = P_\text{QM}(0)</math>
Randomness thus arises at the measuring apparatus, not in the natural process itself.
=== Time evolution ===
Time evolution is the deterministic motion of the modes on the torus; in the low-energy limit <math>E \ll E_\xi</math> the mode equation reduces to the Schrödinger equation. Because of <math>\tilde T \cdot m = 1</math>, each mode has its own time scale (Doc. 334).
=== Entanglement and Bell correlations ===
A Bell state is a topologically connected cylinder configuration in which the individual <math>(z_i, r_i, \theta_i)</math> are not independent. The correlation is read not as action at a distance in <math>\mathbb{R}^3</math> but as a property of the closed <math>T^4</math> geometry. The experimental predictions match those of quantum mechanics; as an open prediction the corpus gives a small geometric deviation from the Tsirelson bound, <math>\Delta\text{CHSH} \approx 10^{-5}</math> per measurement, below today's measurement precision (Docs. 230, 175, 023).
=== Quantum computers ===
The circuit model of Shor's algorithm is digital. The corpus classifies the physical device as an analogue computer with quantum-mechanical precision: error correction averages over many syndrome measurements, and it is open whether this averaging scales with size. On this reading the question is decided not in theory but on the factoring curve, which for honestly executed runs of Shor's algorithm has stood at N = 21 since 2012 (Doc. 343 §G′, Doc. 075).
