The main body of this volume is organized according to seven broad sections that represent core areas of interest in the study of approach and avoidance motivation, including neurophysiology and neurobiology, and evaluative processes. Each section contains a minimum of four chapters that cover a specific aspect of approach and avoidance motivation. The broad applicability of the approach-avoidance distinction makes this Handbook an essential resource for researchers, theorists, and students of social psychology and related disciplines.
