DIFFERENTIATION OF PSYCHOTIC SUBJECTS BY MEANS OF THE META-CONTRAST TECHNIQUE

S mith , G. J. W. Differentiation of psychotic subjects by means of the metacontrast technique. Scad. J. Psychol ., 1968, 9, 3–44.—Sixtyeight psychotic patients tested with the meta-contrast technique (MCT) were divided in six sub-groups according to focal symptoms. Many sub-groups clearly differed with respect to MCT results. In the schizophrenic groups serial discontinuity due to regression was particularly prominent; in the paranoid, non-schizophrenic groups, marked subliminal influence on the frame percept plus other signs of projection. The meaning of psychotic color responses to black-and-white stimuli was also discussed.
