In this new volume, leading researchers provide state-of-the-art perspectives on how social interaction influences the development of knowledge. The book integrates approaches from a variety of disciplines including developmental psychology, psychopathology, philosophy, anthropology, sociology, evolutionary biology, and primatology. It reviews the nature and type of interactions that promote development as well as the conceptual frameworks used to explain the relation between individuals and groups. Social Life and Social Knowledge comprehensively addresses conceptual questions central to understanding human life and development: Is the human form of social life reducible to biological processes? What psychological abilities constitute the specifically human form of social life? What are the processes and contexts within which these abilities develop? How should we conceptualize the links between social life and the development of thought, and how do individuals and society contribute to these processes? The book is intended for philosophers, primatologists, anthropologists, biologists, sociologists, and developmental and educational psychologists interested in social development, social cognition, and developmental psychopathology. It also serves as a resource for courses in social development and those that focus on the intersection between cognition, development, and culture.
