Intensive psychoanalytically-oriented psychotherapy of a schizophrenic girl revealed regressive reprojection of primitive superego functions, hallucinations about the therapist under conditions of stress, and subsequent introjection of an image of the therapist and its assimilation into a new ego-superego integration. An internal critic of great severity, derived mainly from the patient's mother, was modified and stabilized by the patient, and thus became potentially useful for self-control and as a protection against the world.
