Challenging the notion of a blank slate, three studies explore how babies are born with expectations about everyday life.

From curiosity to understanding: researchers unveil the surprising ways that infants learn how to anticipate and respond to the movements of others.

Resolving the debate of nature versus nurture, three scientists show how genetics and environment work together as infants discover who they are.
