Abstract
Psychoanalytic theories suggest that individuals with obsessive defenses, with hysterical defenses, and borderline psychotic individuals respond differently to free association. An experimental analogue of the psychoanalytic session was used to test these ideas. The subjects were 68 male college students, chosen on the basis of the Rorschach and MMPI. Contrary to predictions, obsessive subjects generally associated more freely and showed more involvement in the sessions than hysterical subjects. As expected, hysterical subjects were more silent and blocked and made fewer self-observations than obsessive subjects. Borderline subjects were judged to have less control over drive than the two defensive types.
