The first purpose of this report was a selective review of resent findings concerning neuropsychological profile in patients with schizophrenia. Second, the studies concerning semantic memory and eye movement were introduced. We administered verbal learning test, story memory test, and verbal fluency test. As a result, (1) schizophrenic patients showed failure to spontaneously make use of the implicit semantic category, (2) patients performed worse than controls on the score of thematic sequencing, (3) semantic structure of patients was different from that of controls in animal category. These findings suggest schema in long-term memory is different between patients and controls. The results of brain imaging studies suggest that memory impairments in patients with schizophrenia may be related to dysfunction in both the frontal region and the medial temporal area. Furthermore, the findings of eye movements and vision of peripheral field suggest that restricted eye-scanning in schizophrenia is independent of the size of the object and is not due to poor eye movement, but may be related to impaired cognitive strategy.
