This CARTA series explores the evolution of "Theory of Mind" (ToM), the ability to impute mental states such as beliefs, desires, and intentions to oneself and others, and how ToM makes us uniquely human. Ralph Adolphs (Caltech) begins with a discussion about the definition of ToM, followed by Jessica Sommerville (Univ of Washington) on the Emergence of Theory of Mind in Human Babies, and Sarah-Jayne Blakemore (University College London) on The Social Brain in Adolescence.
