Self psychology emphasizes the development of a stable and integrated sense of self through empathic contacts with other humans, primary significant others conceived of as "selfobjects." Selfobjects meet the developing self's needs for mirroring, idealization, and twinship, and thereby strengthen the developing self. The process of treatment proceeds through "transmuting internalizations" in which the patient gradually internalizes the selfobject functions provided by the therapist. Self psychology was proposed originally by Heinz Kohut, and has been further developed by Arnold Goldberg, Frank Lachmann, Paul and Anna Ornstein, Marian Tolpin, and others.
