Focusing attention on the process by which an individual's internal world is created, this book surveys the development of key concepts relating to internalization. By comparing the psychoanalytic, cognitive-behavioral, existential-humanistic, and family-systems approaches, the book relates the theories of internalization to the practice of psychotherapy. Wallis is a psychiatrist, and Poulton is a psychologist; both are affiliated with the University of Utah. Annotation c. Book News, Inc., Portland, OR (booknews.com)
