The study of the relationship between the person and the situation has had a long history in psychology. Many theories of personality are set on an interpersonal stage and many social phenomena are played out differently as the cast of characters change. At times the study of persons and situations has been contentious, however, recent interest in process models of personality and social interaction have focused on the ways people navigate, influence, and are influenced by their social worlds. Personality and Social Behaviorcontains a series of essays on topics where a transactional analysis of the person and situation has proved most fruitful. Contributions span the personality and social psychology spectrum and include such topics as new units in personality; neuroscience perspectives on interpersonal personality; social and interpersonal frameworks for understanding the self and self-esteem; and personality process analyses of romantic relationships, prejudice, health, and leadership. This volume provides essential reading for researchers with an interest in this core topic in social psychology and may also be used as a text on related upper-level courses.
