Biopsychologyclearly presents the fundamentals of the study of the biology of behavior and makes the topics personally and socially relevant to the student.The defining feature of Biopsychology is its unique combination of biopsychological science and personal, reader-oriented discourse.

It is a textbook that is "untextbooklike." Rather than introducing biopsychology in the usual textbook fashion, it interweaves the fundamentals of the field with clinical case studies, social issues, personal implications, and humorous anecdotes. It tries to be a friendly mentor that speaks directly to the reader, enthusiastically relating recent advances in biopsychological science.
