One feature addressed is Freud's theory of neuroses, which features the psychological, rather than physiological, origins of disturbances previously posited in the medical realm. Other central psychoanalytic concepts considered are childhood trauma, which includes the repression mechanism that produces problematic behaviors. In connection to treatment, "transference" is defined and discussed. A section on psychoanalytic personality theory reviews Freud's definitions of the "id," the "superego," and the "ego." Another section covers child analysis, child development, and delinquency as developed in the concepts of Anna Freud, Sigmund's daughter. An example of a delinquent act involving a peer is explained from a psychoanalytic perspective, and behavioral and personality features which suggest a psychoanalytic diagnosis and resolution are outlined. Some misconceptions or myths about psychoanalysis are identified and refuted. 25 references.
