The Association for the Study of Play (ASP) is the sponsor of the seventh volume in the Play and Culture Studies Series. The ASP is a professional group of researchers who study play.The purpose of this series is to advance knowledge about play and culture. Volume seven presents current theoretical and empirical research on play and culture from a variety of disciplines including psychology, education, and sociology. The book begins with an overview of the twentieth-century and moves from conceptualizing play to significant and timely topics, such as the relationship between play and literacy. Applications to practice and policy implications are presented and include play with action figures; playgrounds; play as an integral part of the human experience; and the value of play with books for toddlers. Research activity and interests of contemporary play scholars are highlighted and discussed in relation to projected problems and needs facing us as we enter the new millennium, such as childhood obesity; play as a venue for social interaction; and play as a method of developing skill for interaction at the local and national levels as adults.
