The study of 14 healthy individuals and.15 schizophrenia patients was performed in condition of visual backward masking. Sensory thresholds were identified using the method of constant stimuli. A special modification of backward masking technique with lateralized presentation of test and masking stimuli was applied to study the lateral characteristics of visual attention. It was found that thresholds of letter stimuli identification were significantly higher in patients with schizophrenia than in healthy subjects. Only in patients the asymmetry of visual perception was revealed with the higher recognition thresholds in the left visual hemifield. Overall data analysis suggests an association of the recognition threshold raising in schizophrenia patients with changes in the interruption mechanism functioning at the neocortex level. |
