Play is one of the most natural and widespread phenomena of childhood. But its purpose and importance for the growing child have been, and remain, a source of puzzlement not only very frequently for parents, but also for social scientists. This book attempts to make clear the vital ways in which play helps the child - to learn about self, about others, and about the world in which he or she lives. The author discusses the origins of playful activities and shows how they become increasingly complex as the child grows and acquires new skills and interests. This book forms part of The Developing Child series and includes recent studies.
