Now in its revised, updated Third Edition, Dr. Stoudemire's introduction to behavioral science remains the ideal text for the human behavior course taken by first-year and second-year medical students. The book emphasizes a biopsychosocial model that enables students to fully understand behavior in health and illness. Over half of the chapters have been completely rewritten for this edition. This text is an excellent companion to the Third Edition of Stoudemire's Clinical Psychiatry for Medical Students.
