A fusion of the full-length and briefer versions that preceded it, Weiten’s PSYCHOLOGY: THEMES AND VARIATIONS, 11th Edition combines a superb thematic organization with practical applications and examples that help readers see beyond research to big-picture concepts. Often described as challenging yet easy to learn from, the book surveys psychology’s broad range of content while illuminating the process of research and its relationship to application, showing both the unity and diversity of psychology’s subject matter and helping learners master the basic concepts and principles of psychology with as little struggle as possible. Weiten’s themes provide unifying threads across chapters that help readers to see the connections among different research areas in psychology. A dynamic illustration program further enhances these themes.
