A major development in psychological science is increased recognition that persons and environments constitute dynamically interacting systems.This book presents advances from internationally renowned researchers in personality, social, cognitive, developmental, and cultural psychology, and other fields, who construct a science of the individual by studying individuals in context. Contributors build on seminal work by Walter Mischel (especially his citation classic, "Toward a Cognitive Social Learning Reconceptualization of Personality," reprinted in the volume). A commentary from Mischel himself places the contributions in historical perspective and articulates the novel portrait of human nature that they yield.
