[An experimental approach to eye-movements: comparison of response patterns between normal subjects and schizophrenic patients (author's transl)].
This experiment attempted to analyse eye movements (opthalmograph) when Ss freely observed 7 types of stimuli projected on the screen. 2 kinds of Ss, a normal control group (5 males, 5 females) and a schizophrenic experimental group (6 males), participated and their response patterns were compared. The results indicated that the schizophrenic group was inferior to the normal Ss in the number of fixations, the mean duration of single fixation, the scan path patterns of the eye mark, the frequency changes of the eye movements within a presentation time, and the dispersion of fixations. These results seemed to show that the schizophrenic group was not able to process much information, and had poor contact with the outer world.
