  • This edition features extensively updated research throughout the chapters. As a result, THEORIES OF PERSONALITY, 12th EDITION, presents the most cutting-edge “tests” of each theory of personality in an accessible way.

  • Pause for Reflections invite students to reflect on the material they have just read and to consider how it applies to their lives and personalities and to people and contexts they care about.

  • DEI Spotlights at the end of each chapter explores how researchers and research building on the different theories of personality help us understand and address issues of Diversity, Equity, and Inclusion.

  • Chapter 15 (Evolutionary Theories of Personality) now covers a major set of theories for why specific personality traits emerge and why they have variations.

  • There are also new learning objectives, review questions, suggested readings and vocabulary terms supporting the ease with which students learn and instructors teach.

  • Chapter outlines, learning objectives, chapter summaries, critical-thinking review questions, key terms, a margin glossary, a full glossary, a complete reference list and annotated reading lists help students master the material.

  • Chapter 15 (Personality in Perspective) reviews the major factors that have emerged from the study of personality theories. It also suggests conclusions related to conscious and unconscious influences (such as genetics, the environment, learning, parental influences and developmental aspects) that students may draw from their study and analysis of the material discussed in the preceding chapters.

  • Chapter One includes a user-friendly introduction to the study of personality with a do-it-yourself adjective checklist to help students describe their own personalities.
