A fusion of the full-length and briefer versions that preceded it, "Psychology: Themes and Variations," 12th Edition, combines thematic organization with practical applications and examples that help students see beyond research to big-picture concepts. Challenging, yet easy to learn from, the book illuminates the process of research and its relationship to application, showing the unity and diversity of psychology's subject matter and helping students master basic concepts and principles of psychology. Consistent with the APA Introductory Psychology Initiative’s endorsement of the value of integrative themes, the text’s themes provide unifying threads across chapters that help students see connections among different research areas in psychology. A dynamic, teaching-oriented illustration program further enhances these themes. The text is available with MindTap.
