In PSYCHOLOGY: THEMES AND VARIATIONS, BRIEFER VERSION, Wayne Weiten continues his proven combination of a scientifically rigorous text with selective pedagogy that makes learning easy for students. Weitenas approach is backed by a straightforward writing style, unparalleled in-text visuals and didactic art program, and in-book review to help users prioritize and retain the core concepts. Weiten surveys psychologyas broad range of content with three aims: to illuminate the process of research and its intrinsic relationship to application (themes); to show both the unity and diversity of the subject (variations), and to invite users to the study of psychology by respecting their ability to master its fundamental concepts. Weitenas themes (including empiricism, theoretical diversity, sociohistorical contexts, multifactorial causation, cultural heritage, heredity and environment, and subjectivity of experience) and variations provide unifying threads across chapters that help users see the connections among different research areas in psychology.
