Outline of Final Research Achievements

This study examined preferences for symmetrical rectangles in patients with schizophrenia and healthy volunteers. In addition, an analysis was performed to examine the association between schizophrenic symptoms and symmetry preference in patients with schizophrenia. Our results suggest that patients with schizophrenia prefer extremely symmetrical rectangles compared to healthy volunteers. In addition, symmetry preference in patients with schizophrenia reflected their symptoms. Moreover, inflexibility, which is characteristic of the disorder, and cognitive disturbances such as attention deficit, are likely involved in the symmetry preference of patients with schizophrenia. Symmetry preference in healthy volunteers reflected their mood such as anger and tension-anxiety.
We should continue to examine the relationship between symmetry preference and low activities in the eye movement.
