Psychobiography, or psychological biography, is the intensive psychological study of a historic person in sociocultural and historical context. Whereas biography reviews the general life pattern and achievements of an individual person, a psychobiography delves deeper, into the psychological motives and drives that led to the individual’s thinking and behavior. Psychobiography is both a specialty within the broad domain of psychology as well as a set of psychological and historiographic research procedures targeted to the intensive study of an individual person. The overwhelming majority of psychobiographies focus on deceased historic personalities, but a small percentage focus on notable individuals still living.
