Although social psychology has been traditionally focused on interpersonal relationships, the cognitive revolution in psychology has had the effect of refocusing some social psychology on intra-psychic processes.This area of psychology has become very popular in recent years, yet there is currently no other textbook available for the study of the self. Republished in its original form by Psychology Press in 2007, this book carefully documents the changing conceptions and the value accorded the self in psychology over time.It further outlines the many alternative conceptions of this increasingly central domain in social psychology.New research and conceptions are juxtaposed with the classic and traditional, providing the reader with a comprehensive introduction to the study of the self.
