This document discusses social cognition in early childhood learning. It makes two main points: 1) Human learning starts at birth, so theories of learning must also start early. 2) Infants learn best from other people through social learning and imitation. The document then provides several examples of research that demonstrate imitation from birth, the role of emotions in learning, neural bases of social learning, the importance of gaze following for language development, and potential extensions to social robots. It argues that a new science of learning should recognize the natural social aspects of early childhood learning through imitation and social interaction.
