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 integrates biology, psychology, and sociology and enables students to fully understand behavior in health and illness. This edition features major revisions to the chapters on the biopsychosocial model in medical practice; culture, ethnicity, and the practice of medicine; psychoanalytic psychology; human sexual development and physiology; childhood and adolescent development; medicine and the family; the psychology and psychobiology of developmental trauma; and neurobiological aspects of behavior. This text is an excellent companion to Stoudemire´s Clinical Psychiatry for Medical Students , also in its newly revised Third Edition.
