. Accordingly, play can range from relaxed, free-spirited and spontaneous through frivolous to planned or even compulsive. Play is not just a pastime activity; it has the potential to serve as an important tool in numerous aspects of daily life for adolescents, adults, and cognitively advanced non-human species (such as primates). Not only does play promote and aid in physical development (such as hand-eye coordination), but it also aids in cognitive development and social skills, and can even act as a stepping stone into the world of integration, which can be a very stressful process. Play is something that most children partake in, but the way play is executed is different between cultures and the way that children engage with play varies universally.


Definitions

The seminal text in the field of play studies is the book ''

'' first published in 1944 with several subsequent editions, in which Johan Huizinga defines play as follows: This definition of play as constituting a separate and independent sphere of human activity is sometimes referred to as the "magic circle" notion of play, a phrase also attributed to Huizinga. Many other definitions exist. Jean Piaget stated, "the many theories of play expounded in the past are clear proof that the phenomenon is difficult to understand." There are multiple aspects of play people home in on when defining it. One definition from Susanna Millar's ''The Psychology of Play'' defines play as: “any purposeful mental or physical activity performed either individually or group-wise in leisure time or at work for enjoyment, relaxation, and satisfaction of real-time or long term needs.” This definition particularly emphasizes the conditions and benefits to be gained under certain actions or activities related to play. Other definitions may focus on play as an activity that must follow certain characteristics including willingness to engage, uncertainty of the outcome, and productivity of the activity to society. Another definition of play from the twenty-first century comes from the National Playing Fields Association (NPFA). The definition reads as follows: “play is freely chosen, personally directed, intrinsically motivated behaviour that actively engages the child.” This definition focuses more on the child's freedom of choice and personal motivation related to an activity.


Forms

Play can take the form of improvisation or pretense, interactive, performance, mimicry, games, sports, and thrill-seeking, such as extreme or dangerous sports (sky-diving, high-speed racing, etc.). Philosopher

organizations for educational entertainment. The California-based National Institute for Play describes seven play patterns: * Attunement play, which establishes a connection, such as between newborn and mother. * Body play, in which an infant explores the ways in which his or her body works and interacts with the world, such as making funny sounds or discovering what happens in a fall. * Object play, such as playing with toys, banging pots and pans, handling physical things in ways that use curiosity. * Social play, play which involves others in activities such as tumbling, making faces, and building connections with another child or group of children. * Imaginative or pretend play, in which a child invents scenarios from his or her imagination and acts within them as a form of play, such as princess or pirate play. * Storytelling play, the play of learning and language that develops intellect, such as a parent reading aloud to a child, or a child retelling the story in his or her own words. * Creative play, by which one plays with imagination to transcend what is known in the current state, to create a higher state. For example, a person might experiment to find a new way to use a musical instrument, thereby taking that form of music to a higher plane; or, as Einstein was known to do, a person might wonder about things which are not yet known and play with unproven ideas as a bridge to the discovery of new knowledge. Another classification system uses categories like these: * Replica play, such as playing with toy versions of food in a play kitchen * Challenge play, such as solving a

In young children, play is frequently associated with cognitive development and socialization. Play that promotes

suggest that play promotes flexibility of mind, including adaptive practices such as discovering multiple ways to achieve a desired result, or creative ways to improve or reorganize a given situation (Millar, 1967; Shonkoff & Phillips, 2000). As children get older, they engage in board games, video games and computer play, and in this context the word gameplay is used to describe the concept and theory of play and its relationship to rules and game design. In their book, ''Rules of Play'', researchers Katie Salen and Eric Zimmerman outline 18 schemas for games, using them to define "play", "interaction" and "design" formally for behaviorists. Similarly, in his book ''Half-Real: Video Games between Real Rules and Fictional Worlds'', game researcher and theorist Jesper Juul explores the relationship between real rules and unreal scenarios in play, such as winning or losing a game in the real world when played together with real-world friends, but doing so by slaying a dragon in the fantasy world presented in the shared video game. Play is explicitly recognized in Article 31 of the Convention on the Rights of the Child (adopted by the General Assembly of the

History of childhood playtime

American historian Howard Chudacoff has studied the interplay between parental control of toys and games and children's drive for freedom to play. In the colonial era, toys were makeshift and children taught each other very simple games with little adult supervision. The market economy of the 19th century enabled the modern concept of childhood as a distinct, happy life stage. Factory-made dolls and doll houses delighted young girls. Organized sports filtered down from adults and colleges, and boys learned to play with a bat, a ball and an impromptu playing field.


20th Century

With the rise of motor vehicle traffic in the 20th century, teenagers were increasingly organized into club sports supervised and coached by adults, with swimming taught at summer camps and through supervised playgrounds. Under the

Cultural differences of play

The act of play time is a cross-cultural phenomenon that is universally accepted and encouraged by most communities; however, it can differ in the ways that is performed. Some cultures, such as Euro-American cultural heritages, encourage play time in order to stress cognitive benefits and the importance of learning how to care for one's self. Other cultures, such as people of African American or Asian American heritages, stress more group oriented learning and play where kids can learn what they can do with and for others. Parent interactions when it comes to playtime also differs drastically within communities. Parents in the Mayan culture do interact with their children in a playful mindset while parents in the United States tend to set aside time to play and teach their children through games and activities. In the Mayan community, children are supported in their playing but also encouraged to play while watching their parents do household work in order to become familiar with how to follow in their footsteps. All around the world, children use different natural materials like stones, water, sand, leaves, fruits, sticks and a variety of resources to play. In addition, there are groups that have access to crafts, industrialized toys, electronics and video-games. In Australia, games and sports are part of play. There, play can be considered as preparation for life and self- expression, like in many other countries. Groups of children in Efe of the Democratic Republic of Congo can be seen making ‘food’ from dirt or pretending to shoot bows and arrows much like their elders. These activities are similar to other forms of play worldwide. For instance, children can be seen comforting their toy dolls or animals, anything that they have modeled from adults in their communities. In Brazil, we can find children playing with balls, kites, marbles, pretend houses or mud kitchens, like in many other countries. In smaller communities they use mud balls, little stones or cashews to replace marbles. At an indigenous community of Sierra Nevada de Santa Marta in Colombia, children's play is highly valued and encouraged by leaders and parents. They interact with the children of different ages and explore together different environments to let the children express themselves as part of the group. Some children in the Sahara use clay figures as their forms of playful toys. Toys in general are a representation of cultural practices. They usually illustrate characters and objects of a community. Play time can be used as a way for children to learn the different ways of their culture. Many communities use play to emulate work. The way in which children mimic work through their play can differ according to the opportunities they have access to, but it is something that tends to be promoted by adults.

Electronics over the past 10 years have been looked as a form of playtime but researchers have found that most electronic play leads to lack of motivation, no social interaction and can lead to obesity. Play is originally based on the idea of children using their creativity while developing their imagination, dexterity, physical, cognitive and emotional strength. Dramatic play is common in younger children. For the youth community to benefit from playtime, the following are recommended: * Give children ample, unscheduled time to be creative to reflect and decompress * Give children “true” toys, such as blocks or dolls for creativity * Youth should have a group of supportive people around them (teammates, coaches, and parents) with positive relationships * Youth should possess skill development; such as physical, interpersonal, and knowledge about the sport * Youth should be able to make their own decisions about their sport participation * Youth should have experiences that are on par with their certain needs and developmental level

Adults

Although adults who engage in high amounts of play may find themselves described as "childish" or "young at heart" by less playful adults, play is an important activity, regardless of age. Creativity and happiness can result from adult play, where the objective can be more than fun alone, as in adult expression of the arts, or curiosity-driven science."Tim Brown on Creativity and Play,"

Some adult "hobbies" are examples of such creative play. In creative professions, such as design, playfulness can remove more serious attitudes (such as shame or embarrassment) that impede brainstorming or artistic experimentation in design. Imaginative play and role play may allow adult individuals to practice useful habits such as learned optimism, which is helpful in managing fear or terrors. Play also offers adults the opportunity to practice concepts that may not have been explicitly or formally taught (e.g. how to manage misinformation or deceit). Thus, even though play is just one of many tools used by effective adults, it remains a necessary one.

and stress. Decreased stress leads to less illness, which results in lower health care costs. Play at work may help employees function and cope when under stress, refresh body and mind, encourage teamwork, trigger creativity, and increase energy while preventing burnout. Studies show that companies that encourage play at work, whether short breaks throughout the day or during lunch breaks experience more success because it leads to positive emotion amongst employees. Risk taking, confidence in presenting novel ideas, and embracing unusual and fresh perspectives are common characteristics associated with play at work. Play can increase self-reported job satisfaction and well-being. Employees experiencing positive emotions are more cooperative, more social, and perform better when faced with complex tasks. Contests, team-building exercises, fitness programs, mental health breaks and other social activities, will make the work environment fun, interactive, and rewarding. Also playfighting, i.e. playful fights or fictive disputes, may contribute to organizations and institutions, as in youth care settings. Staff tries to down-key playfight invitations to “treatment” or “learning,” but playfighting also offers youth and staff identificatory respite from the institutional regime. Wästerfors (2016) has found that playfighting is a recurrent pattern in the social life of a youth care institution and sits at the core of what inmates and staff have to deal with

. For this reason, research has begun to investigate methods to maintain and/or improve quality of life among older adults. Similar to the data surrounding children and adults, play and activity are associated with improved health and quality of life among seniors. Additionally, play and activity tend to affect successful aging as well as boost well-being throughout the lifespan. Although children, adults, and seniors all tend to benefit from play, older adults often perform it in unique ways to account for possible issues, such as health restrictions, limited accessibility, and revised priorities. For this reason, elderly people may partake in physical exercise groups, interactive

, and social forums specifically geared towards their needs and interests. One qualitative research study found older adults often chose to engage in specific games such as dominoes, checkers, and bingo for entertainment. Another study indicated a common pattern within game preferences among older adults; seniors often favor activities that encourage mental and physical fitness, incorporate past interests, have some level of competition, and foster a sense of belonging. Researchers investigating play in older adults are also interested in the benefits of technology and video games as therapeutic tools. Studies show these outlets can lower the risk of developing particular diseases, reduce feelings of social isolation and stress, as well as promote creativity and the maintenance of cognitive skills. As a result, play has been integrated into physiotherapy and occupational therapy interventions for seniors.Jung, Y., Li, K.J., Ng, J.S., Wong, G.L.C., & Lee, K. (2009).

/ref> The ability to incorporate play into one's routine is important because these activities allow participants to express creativity, improve verbal and non-verbal intelligence as well as enhance balance. These benefits may be especially crucial to seniors because evidence shows cognitive and physical functioning declines with age. However, other research argues it might not be aging that is associated with the decline in cognitive and physical capabilities. More specifically, some studies indicate it could be the higher levels of inactivity within older adults that may have significant ramifications on their health and well-being. With attention to these hypotheses, research shows play and activity tend to decline with age which may result in negative outcomes such as social isolation, depression, and mobility issues. American studies found that only 24% of seniors took part in regular physical activity and only 42% use the internet for entertainment purposes. In comparison to other age groups, the elderly are more likely to experience a variety of barriers, such as difficulty with environmental hazards and accessibility related issues, that may hinder their abilities to execute healthy play behaviours. Similarly, although playing may benefit seniors, it also has the potential to negatively impact their health. For example, those who play may be more susceptible to injury. Investigating these barriers may assist in the creation of useful interventions and/or the development of preventative measures, such as establishing safer recreational areas, that promote the maintenance of play behaviours throughout elderly life. A significant amount of literature suggests a moderate level of play has numerous positive outcomes in the lives of senior citizens. In order to support and promote play within the older population, studies suggest institutions should set up more diverse equipment, improve conditions within recreational areas, and create more video games or online forums that appeal to the needs of seniors.


Other animals

Evolutionary psychologists believe that there must be an important benefit of play, as there are so many reasons to avoid it. Many animals are often injured during play, become distracted from predators, and expend valuable energy. In rare cases, play has even been observed between different species that are natural enemies such as a

. Yet play seems to be a normal activity with animals who occupy the higher strata of their own hierarchy of needs. Animals on the lower strata, e.g. stressed and starving animals, generally do not play. However, in wild Assamese macaques physically active play is performed also during periods of low food availability and even if it is at the expense of growth, which strongly highlights the developmental and evolutionary importance of play. The social cognitive complexity of numerous species, including dogs, have recently been explored in experimental studies. In one such study, conducted by Alexandra Horowitz of the University of California, the communication and attention-getting skills of dogs were investigated. In a natural setting, dyadic play behavior was observed; head-direction and posture was specifically noted. When one of the two dogs was facing away or otherwise preoccupied, attention-getting behaviors and signals (nudging, barking, growling, pawing, jumping, etc.) were used by the other dog to communicate the intent and/or desire to continue on with the dyadic play. Stronger or more frequent signaling was used if the attention of the other dog was not captured. These observations tell us that these dogs know how play behavior and signaling can be used to capture attention, communicate intent and desire, and manipulate one another. This characteristic and skill, called the "attention-getting skill" has generally only been seen in humans, but is now being researched and seen in many different species. Observing play behavior in various species can tell much about the player's environment (including the welfare of the animal), personal needs, social rank (if any), immediate relationships, and eligibility for mating. Play activity, often observed through action and signals, often serves as a tool for communication and expression. Through mimicry, chasing, biting, and touching, animals will often act out in ways so as to send messages to one another; whether it's an alert, initiation of play, or expressing intent. When play behavior was observed for a study in Tonkean macaques, it was discovered that play signals weren't always used to initiate play; rather, these signals were viewed primarily as methods of communication (sharing information and attention-getting). One theory – "play as preparation" – was inspired by the observation that play often mimics adult themes of survival.

and zebras play by running and leaping as they acquire speed and agility. Hoofed mammals also practice kicking their hind legs to learn to ward off attacks. Indeed, time spent in physical play accelerates motor skill acquisition in wild Assamese macaques. While mimicking adult behavior, attacking actions such as kicking and biting are not completely fulfilled, so playmates do not generally injure each other. In social animals, playing might also help to establish dominance rankings among the young to avoid conflicts as adults. John Byers, a zoologist at the

in Alberta, Canada, discovered that play may shape the brain in other ways, too. Young mammals have an overabundance of brain cells in their cerebrum (the outer areas of the brain – part of what distinguishes mammals). There is evidence that play helps the brain clean up this excess of cells, resulting in a more efficient cerebrum at maturity. Marc Bekoff (a

evolutionary biologist) proposes a "flexibility" hypothesis that attempts to incorporate these newer neurological findings. It argues that play helps animals learn to switch and improvise all behaviors more effectively, to be prepared for the unexpected. There may, however, be other ways to acquire even these benefits of play: the concept of equifinality. The idea is that the social benefits of play for many animals, for example, could instead be garnered by grooming. Patrick Bateson maintains that equifinality is exactly what play teaches. In accordance with the flexibility hypothesis, play may teach animals to avoid "false endpoints". In other words, they will harness the childlike tendency to keep playing with something that works "well enough", eventually allowing them to come up with something that might work better, if only in some situations. This also allows mammals to build up various skills that could come in handy in entirely novel situations. A study on two species of monkeys ''Semnopithecus entellus'' and ''Macaca mulatta'' that came into association with each other during food provisioning by pilgrims at the Ambagarh Forest Reserve, near Jaipur, India, shows the interspecific interaction that developed between the juveniles of the two species when opportunity presented itself.

Physical, mental and social

Various forms of play, whether it is physical or mental, have influenced cognitive abilities in individuals. As little as ten minutes of exercise (including physical play), can improve cognitive abilities. These researchers did a study and have developed an "exergame" which is a game that incorporates some physical movement but is by no means formal exercise. These games increase one's heart rate to the level of aerobics exercise and have proven to result in recognizable improvements in mental faculties In this study they use play in a way that incorporates physical activity that creates physical excursions. The results of the study had statistical significance. There were improvements in math by 3.4% and general improvements in recall memory by 4% among the participants of the study. On the other hand, other research has focused on the cognitive effects of mentally stimulating play. Good toys for young children need to match their stages of development and emerging abilities. Younger children can benefit from simply learning about their geometric shapes, while older children can build various original constructions. Playing video games is one of the most common mediums of play for children and adults today. There have been mixed reviews on the effects of video games. Despite this, according to a research conducted by Hollis (2014), "

occurs in moderation". Play can also influence one's social development and social interactions. Much of the research focuses on the influence play has on child social development. There are different forms of play that have been noted to influence child social development. One study conducted by (Sullivan, 2003) explores the influence of playing styles with mothers versus playing styles with fathers and how it influences child social development. This article explains that "integral to positive development is the child's social competence or, more precisely, the ability to regulate their own emotions and behaviors in the social contexts of early childhood to support the effective accomplishment of relevant developmental tasks. Social benefits of play have been measured using basic interpersonal values such as getting along with peers.Sullivan, C. (2003)
The benefits of parent-child play for the social development of preschoolers with varying levels of anxiety problems
ProQuest, UMI Dissertations.
One of the social benefits that this researcher has uncovered is that play with parents has proven to reduce anxiety in children. Having play time with parents that involves socially acceptable behaviour makes it easier for children to relate to be more socially adjusted to peers at school or at play Social development involving child interaction with peers is thus an area of influence for playful interactions with parents and peers.


Play in educational practices


Anji play

Anji play (安吉游戏 in simplified Chinese, 安吉遊戲 in traditional Chinese) is an educational method based on children's self-directed play in outside spaces, using simple tools made of natural material. The teachers and instructors only observe and document the children's independent play. The method was created by Cheng Xueqin and is organized in two hours of free play when the children choose the available material they want to use and build structures to play. While planning, experimenting, building and using the structures to play, the children have the opportunity to interact with peers, to think critically about what may work, to discuss the plan and organize the construction hard work. The process is observed and recorded by the teachers and instructors without intervention, even in instances of possible risk. Before and after the two hours of play, the children have the opportunity to express their plans and discuss with their peers. After the play, they get the opportunity to draw, write or explain what they did. Then, they watch the videos recorded the same day and explain how they played and comment on each other's creations. Anji play is also called “true play” and its guiding principles are love, risk, joy, engagement, and reflection. This method of self-initiated and self-directed play is applied at the pre-schools (to children from 3 to 6 years-old) in Anji county, East China.
