A Psychophysiological Investigation of the Rorschach Colour and Form Determinants

Summary The Rorschach colour-emotion and form-control hypotheses were investigated by determining whether subjects would react differently psychophysiologically while giving colour dominant or form responses. Slides of the Rorschach plates no. II, III, V, VIII, IX and X were presented to 42 subjects while respiration (as control only) vasomotor changes, skin resistance and heart rate were recorded. All physiological changes (except respiration) found in conjunction with Rorschach C, CF, FC, and F responses were transformed to Lacey's autonomic lability scores. Some indications of different physiological reactions to colour and form were found. The results indicated the possible existence of “emotional” and “controlled” groups of subjects who tended to react differently, verbally and physiologically, to the Rorschach stimuli.
