Play Behavior and Playfulness in Adulthood

Abstract Although research has established play behavior and playfulness as important to the well‐being of children and animals, researchers have not typically considered the importance or implications of play in human adults. This is surprising given that play behavior is a topic of high relevance to social psychology. Definitional issues, a lack of a theoretical framework, and a dearth of standardized measures have posed obstacles in the advancement of this interesting research area, which is ripe for investigation. In this review, we summarize the extant literature, identify strengths and weaknesses of this literature, propose definitions to guide future work in this area, identify relevant theories that may be expanded to provide a framework for programmatic research on play in adulthood, and elucidate avenues for future research. Our aim is to encourage the development of this research area within social psychology.
