Focuses on three main issues emerging from studies of conceptual development: (1) young children's naive theories of the world; (2) how innate constraints in conceptual development work; and (3) how innate and sociocultural constraints are integrated. Maintains that early development of core domains of thought (naive psychology, physics, and biology) is guided by both types of constraints. (KB)
