In the World Library of Psychologists series, international experts present career-long collections of what they judge to be their finest pieces—extracts from books, key articles, salient research findings, and their major practical theoretical contributions. In this volume, Roy F. Baumeister reflects on his distinguished career as an eminent scholar in the field of self-control and self-regulation, as well as belonging, rejection, free will, and consciousness. Offering a unique perspective on both the program of research in ego-depletion as one of social psychology’s most widely successful theories, and its position in the changing landscape of the scientific field, the book charts Baumeister’s development as one of the pioneers of study into self-control. Featuring a newly written introductory piece in which the author offers a unique insight into the initial findings that led to an eventual theory of ego-depletion, this collection will give readers a vital understanding of how the hugely influential theory of ego depletion first came to be developed, and is essential reading for students and researchers in self-control and self-regulation.
