"A stand-out volume for scholars of mind and behavior. The first of its kind, it integrates work on social cognition and social behavior, and it addresses in detail cross-species and cross-age constants and change. There is an impressive amount to learn from these state-of-the-art, clearly written contributions." – Bertram F. Malle, Professor, Department of Cognitive, Linguistic and Psychological Sciences, Brown University"This is an outstanding collection of work on social cognition, bringing together both developmental and comparative perspectives. It will be a definitive text on these topics for years to come. Any student interested in the origins of empathy, altruism and prosocial behavior will benefit from this engaging and comprehensive work." – Laura Schulz, Associate Professor, Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology
