After defining the content of the unconscious in self psychology, the place of repressed archaic selfobject needs, the development of the concept of selfobject is described. The three basic selfobject transferences are portrayed, and the circumstances of healing in the therapeutic process from a Kohutian versus Freudian point of view are defined. Consecutively, the diversifications in the conceptions of the unconscious in self psychology are explained, beginning with intersubjective systems theory and then a self and motivational systems view. The study and integration of ideas from developmental psychology, that is, attachment theory, implicit knowledge, memory research, and neurobiology, highlight that self psychology is able to integrate usefully new paradigms from other disciplines.
