Dr. James W. Kalat's "Biological Psychology" is the best selling text in the market because of its extremely high level of scholarship, clear and occasionally humorous writing style, and precise examples integrated throughout the text. Throughout all nine editions, the goal has been to make biological psychology accessible to psychology students, not just to biology majors and pre-meds. The goal has also been to convey the excitement of the search for biological explanations of behavior. Kalat argues that biological psychology is "the most interesting topic in the world," and this text convinces many students. Try-it-yourself activities in the book and on-line help illustrate phenomena and procedures described in the text. Accuracy, currency and a clear presentation style have always been the trademark signature of this text and this Ninth Edition has taken these qualities to the next level.
