The second edition of The Oxford Handbook of Personality and Social Psychology captures the history, current status, and future prospects of personality and social psychology—presented not as a set of parallel accounts, but as an integrated perspective on the behavior of persons in social contexts. This handbook combines these two fields in a single integrated volume, offering a unique and generative agenda for psychology. It is dedicated to the proposition that personality and social psychology are best viewed in conjunction with one another and that the synergy to be gained from considering links between the two fields can do much to move both fields forward and to enrich our understanding of human nature. Such interdependence is particularly crucial if one wishes to address the ongoing functioning of persons in their natural environments, where splits between person and situation are not so easily fashioned. The chapters of the Handbook weave together work from personality and social psychology, not only in areas of long-standing concern, but also in newly emerging fields of inquiry, addressing both distinctive contributions and common ground. In so doing, they offer compelling evidence for the power and the potential of an integrated approach to personality and social psychology.
