Weiten's PSYCHOLOGY: THEMES AND VARIATIONS, EIGHTH 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. Interactive multimedia and online resources that are fully integrated with the text—including PsykTrek™ 3.0, CengageNOW™ (with an eBook), and downloadable audio study tools—provide additional paths to learning. Instructors receive support from videos; PowerLecture™: A One-Stop Microsoft® PowerPoint® Tool, featuring readymade lecture slides; and a YouTube resource guide.
