Weiten's PSYCHOLOGY: THEMES AND VARIATIONS, 8E International Edition maintains this book's strengths while addressing market changes with new learning objectives, a complete updating, and a fresh new design. The text continues to provide a unique survey of psychology that meets three goals: to demonstrate the unity and diversity of psychology's subject matter, to illuminate the research process and its link to application, and to make the text challenging and thought-provoking yet easy from which to learn. Weiten accomplishes the successful balance of scientific rigor and a student-friendly approach through the integration of seven unifying themes, an unparalleled didactic art program, real-life examples, and a streamlined set of learning aids that help students see beyond research to big-picture concepts. Major topics typically covered in today's courses are included, such as evolutionary psychology, neuropsychology, biological psychology, positive psychology, applied psychology, careers, and multiculturalism and diversity.
