Biopsychology presents a clear, engaging introduction to biopsychological theory and research through a unique combination of biopsychological science and personal, reader-oriented discourse. Original author John Pinel and new co-author Steven Barnes address students directly and interweave the fundamentals of the field with clinical case studies, useful metaphors, and memorable anecdotes that make course material personally and socially relevant to readers. In addition to expanded learning objectives that guide students through the course, the Tenth Edition has been thoroughly updated to reflect this rapidly progressing scientific field.
