Do children have a theory of mind? If they do, at what age is it acquired? What is the content of the theory, and how does it differ from that of adults? The Child's Theory of Mind integrates the diverse strands of this rapidly expanding field of study. It charts children's knowledge about a fundamental topic - the mind and characterizes that developing knowledge as a coherent commonsense theory, strongly advancing the understanding of everyday theories as well as the commonsense theory of mind.

This book is clearly one of the most comprehensive, original, and important contributions this young field has yet seen. Written by one of the field's foremost investigators, the book presents his view of the nature and course of theory-of-mind development... Wellman's book is an absolute must for devotees of this area of cognitive development, and I strongly recommend it to anyone interested in the nature and development of significant human concepts."
