This classic of developmental psychology provides a clear and still engaging overview of the typical perception and interpretation patterns of preschool children. How do children interpret the relationship between words and objects, the origin and characteristics of natural phenomena, and the causes of events? In this book, Jean Piaget analyzes the typical traits of children's understanding of the world and addresses fundamental questions of developmental psychology. Based on his own surveys regarding various aspects of children's logic, he incorporates the results of contemporary research and compiles them into a comprehensive explanatory model.
