antilibidinal ego

in the object relations theory of British psychoanalyst W. Ronald D. Fairbairn (1889–1964), the portion of the ego structure that is similar to Sigmund Freud’s superego. The antilibidinal ego constitutes a nonpleasure-gratifying, self-deprecatory, or even hostile self-image; it is posited to develop out of the unitary ego present at birth when the infantile libidinal ego (similar to the id) experiences deprivation at the hands of the parent and the infant suppresses his or her frustrated needs. Also called internal saboteur. See Fairbairnian theory.
