This new edition provides a comprehensive review of the major theories in personality psychology. Extensively revised and updated the text includes a new chapter on Eysenck's Theory, and in response to reviewers' requests the chapter on Sheldon has been deleted (the major points of his theory are now incorporated into the introductory chapters on trait perspectives.) Many new case studies have been added in which the theories are applied to the treatment of personality problems. Chapter One defines personality and illustrates criteria for judging a theory. Readers can then apply these criteria to each theory discussed. Other successful features of previous editions are continued: a consistent approach from topic to topic allows students to compare and contrast theories; each major theoretical position is introduced by an objective overview of the theorist's concepts and propositions; and the final chapter introduces some of the issues and latest research developments in personality psychology, including the need for an interactional theory of personality. This book should be of interest to degree and diploma students on social and behavioural science courses.
