This study was undertaken to compare the difference between normal and schizophrenic persons metrically by using indices of eye movements; "number", "time of fixation", "time of a single fixation" and "diffusibility of fixation points". The schizophrenic group consisted of 3 males and 3 females who are all hebephrenic type and their length of hospitalization ranged from 5 years to 15 years. The normal group consisted of 2 males and 2 females who are all students. 10 pairs of figures, which consisted of 5 types (ex. Fig. 1,6), were presented with a slide projector to each subject in order. The presented time of a single pair was 10 seconds. Eye movements were recorded by an eye-camera (opthalmograph) and a 16 mm cine-camera, 12 frames per sec.The results were as follows;1. Both groups spent a longer fixation time in the figure of castle, girl's face and dishes than in a triangle and white space.2. The normal group spent a longer fixation time than the schizophrenic group in a simple geometrical figure.3. The normal group spent a longer fixation time in left direction. This is not connected with the type of figures. The schizophrenic group does not have such a tendency.4. The schizophrenic group shows a tendency of weighting their fixation time extremely partial to one side in pairs of pictures, more than the normal group.5. In time of a single fixation, which may be a clue of internal information-processing, the schizophrenic group spent a longer time than the normal group.6. The distribution of the schizophrenic group tends to concentrate in a small space.
