A completely revised and updated edition of a much-acclaimed textbook providing a critical introduction to human personality for psychology students. Levels of Personality carefully avoids the traditional 'catalogue of theories' approach. Instead it relates theories to each other within a conceptual framework of different levels of behaviour, moving inwards and downwards from 'surface level' explanations. Analytic case studies then apply these levels of understanding to areas of special interest such as aggression and sexuality. The author adopts a deep analytical and critical approach and questions whether personality theory and research have really addressed important questions, or produced useful answers. This new edition incorporates two new chapters on personality disorders and on personality in the workplace, as well as improved pedagogical features including statistics boxes, assessment boxes, relevant websites and key references for each chapter.
