This PowerPoint presentation summarizes chapter 5 of the textbook, which covers three major perspectives in abnormal psychology: the psychodynamic perspective, the humanistic-existential perspective, and the interpersonal perspective. The psychodynamic perspective is based on Freud's concepts of the id, ego, superego, and defense mechanisms. The humanistic-existential perspective focuses on self-actualization and the therapist acting as a facilitator. The interpersonal perspective emphasizes interactions among people and how social relationships can influence disorders.
