The experimental definition of the stimulus properties of Rorschach cards and their effects upon behavior was undertaken by using operant response measures to differentiate the reinforcing properties of 3 Rorschach cards. Each population of 30 normal females and 30 schizophrenic females was divided into 3 groups. By pressing a button Ss in each group could occasionally view a Rorschach card which had been placed in a box. Statistically, there were no significant differences between cards or populations due to response variability generated by experimental conditions. Revisions in procedure were suggested to improve the stability of response measures.
