A Psychophysical Approach to the Study of Individuals' Perceptions of Rorschach Cards

Abstract

An analysis was performed on individuals' perceptions of the cards in the Rorschach test using psychophysical methodology. Ss gave similarity ratings on a numerical scale. Both a dimensional and a category analysis were performed on individual and group data. The results gave a clear and psychologically interpretable structure. The perception of the Rorschach cards was shown to be a function of the three stimulus properties: (a) open form, (b) closed form, and (c) color. The agreement in perceptual structure among individuals was shown to be considerable in this homogeneous “normal” group. Some sex differences were observed. Further use of the methodology is discussed.
