Abstract
The fully revised second edition of this classic text ushers the study of personality into the 21st century. Chapters from foremost authorities provide a historical overview of modern personality theory, bring major theoretical perspectives into focus, and report on the current state of the science in a range of key domains. Documenting the ongoing evolution of psychoanalytic, trait, social cognitive, and interactional approaches, the volume explores the dynamic interface between personality psychology and other disciplines. In particular, the recent explosion of knowledge about biological aspects of personality is reflected in chapters on evolutionary psychology, behavioral genetics, neuroscience, and temperament. Major research is also presented on such defining topics as the self; the psychological unconscious; motivational processes; emotion and emotion regulation; stress, coping, and health; interpersonal behavior; personality assessment; and more. Longitudinal studies are uniquely suited to answer five questions about personality development across the life course. This chapter reviews the answers to these questions. First, evidence about the early origins of personality is evaluated. Second, the types of continuity and change that are observed across the life course are examined. Third, the factors that moderate continuity and change are reviewed. Finally, the authors turn to the dual task of developmental research on continuity and change, and seek to describe the processes and mechanisms that promote or transform the continuity of personality across the life course.
