Studies of rats and some primates show that rough-and-tumble play among juveniles improves social competence, cognition, and emotional regulation later in life. Most critically, such play makes animals better able to respond to unexpected situations. But not all animals engage in play, and not all animals that play appear to gain these benefits.…

Play helps children learn language, the authors claim, and they review the evidence for it. They suggest that play benefits children's language development because it incorporates many of the socially interactive and cognitive elements known to enhance language skills. Although much of this evidence proves correlational, they point to a…

In this article, the author outlines Plato's notions of play in ancient Greek culture and shows how the philosopher's views on play can be best appreciated against the background of shifting meanings and evaluations of play in classical Greece. Play--in various forms such as word play, ritual, and music--proved central to the development…

The authors contend that many cognitive abilities and affective processes important in creativity also occur in pretend play and that pretend play in childhood affects the development of creativity in adulthood. They discuss a variety of theories and observations that attempt to explain the importance of pretend play to creativity. They argue that…

An article by Angeline S. Lillard and others published in the January 2013 issue of "Psychological Bulletin" about the impact of pretend play on child development raised a number of issues about play studies and child psychology. The article claimed that, contrary to current theories on the subject, the evidence of many studies does not…

The overwhelming majority of play research concerns juveniles. However, a full understanding of the phenomenon requires knowledge of play and playfulness across the life spans of those animals, including humans, who play in adulthood. The authors investigate a theory of play based on Darwin's concept of sexual selection that may account for the…

Red colobus monkeys are playful primates, making them an important species in which to study animal play. The author examines play behaviors and responses in the species for its play initiation events, age differences in initiating frequency and initiating behavior, and the types of social play that result from specific initiating behaviors. Out…

Peer-play experiences are a vital part of children's socialization, development, and culture. Children with autism face distinct challenges in social and imaginary play, which place them at high risk for being excluded by peers. Without explicit support, they are likely to remain isolated from peers and the consistent interactive play that…

Over the past half century, in the United States and other developed nations, children's free play with other children has declined sharply. Over the same period, anxiety, depression, suicide, feelings of helplessness, and narcissism have increased sharply in children, adolescents, and young adults. This article documents these historical changes…

Many research findings about animal play apply to children's play, revealing structural and functional similarities with mammals in general and primates in particular. After an introduction to life-history theory, and before turning to humans, the author reviews research about the two mammals in which play has been studied the most extensively:…

From an evolutionary perspective, the normal social play of children involves kids of various ages. Our human and great-ape ancestors most likely lived in small groups with low birth rates, which made play with others of nearly the same age rare. Consequently, the evolutionary functions of children's social play are best understood by examining…

Creating play environments for children usually requires groups of adults working together. An extensive scientific literature describes how groups function to achieve shared goals in general terms, and groups attempting to empower play may find this literature useful. Design principles for managing natural resources, identified by Elinor Ostrom…

Few studies of adult playfulness exist, but limited research on older adults and playfulness suggests that playfulness in later life improves cognitive, emotional, social, and psychological functioning and healthy aging overall. Older adults represent a rapidly growing segment of the U.S. population, underscoring the need to understand the aging…

For most children in North America, Halloween is one of the most exciting holidays of the year. But some critics insist that its emphasis on ready-made costumes, store-bought candy, and trick-or-treating seduces children into cultural passivity and socializes them to mindless consumption. These critics argue that trick-or-treating was an inherited…
