It is a projective personality test, the same category of the most-known Rorschach test, but with the crucial difference of being nonverbal. The test consists in showing the examinee a series facial photographs, displayed in six groups of eight each. All 48 subjects featured in the photogtaphs are mental patients, each group containing a photo of a person whose personality had been classified as homosexual, a sadist, an epileptic, an hysteric, a katatonic, a paranoid, a depressive and a maniac. The subject is asked to choose the two most appealing and the two most repulsive photos of each group. The choices will supposedly reveal the subject satisfied and unsatisfied instinctive drive needs, and the subject's dimensions of personality. Each photo is supposed to be a stimulus apt to detect the pulsional drive tendencies of the examinee, from which the main personality traits can surface. Szondi said that for some disturbed examinees the stimulus of seeing the photo of a mental patient with the same pathology caused them to have crisis and convulsions during the test examination.
