  3. 3. Perspectives on Psychological Disorders • Medical perspective - the perspective that suggests that when an individual displays symptoms of abnormal behavior, the root cause will be found in a physical examination of the individual, which may reveal a hormonal imbalance, a chemical deficiency, or a brain injury. • Psychoanalytic perspective - the perspective that suggests that abnormal behavior stems from childhood conflicts over opposing wishes regarding sex and aggression.
  4. 4. • Behavioral perspective - the perspective that looks at the behavior itself as the problem. • Cognitive perspective - the perspective that suggests that people’s thoughts and beliefs are a central component of abnormal behavior. • Humanistic perspective - the perspective that emphasizes the responsibility people have for their own behavior, even when such behavior is abnormal.
