Recent studies have suggested that this bias is reduced or absent in people with schizophrenia.\u0000\u0000\u0000METHODS\u0000Fifty first-episode and 50 patients with chronic schizophrenic and 50 control subjects were given a brief neuropsychologic battery that included a Happy-Sad Chimeric Face test and the Benton Facial Recognition Test. All patients were rated on the Positive and Negative Syndrome Scale of Schizophrenia after 4 weeks of neuroleptic treatment. All were right handed\u0000\u0000\u0000RESULTS\u0000The patients with schizophrenia showed a significantly weaker perceptual left hemispatial bias compared with controls. In fact the mean bias was in the opposite direction in the chronic group. There was no correlation between left hemispatial bias and either positive or negative symptoms, current medication dose, or mood. Results from the Benton test revealed a performance deficit among the patients with schizophrenia compared with controls but was not correlated with performance on the chimeric faces test in the patients.\u0000\u0000\u0000CONCLUSIONS\u0000The results confirm a specific deficit in right hemisphere attentional functions in schizophrenia, which is separate from a general impairment in facial processing. The deficit is most marked in chronic patients but further study is required to determine whether this is a consequence of prolonged illness.","PeriodicalId":79516,"journal":{"name":"Neuropsychiatry, neuropsychology, and behavioral neurology","volume":"9 1","pages":"72-8"},"PeriodicalIF":0.0,"publicationDate":"2002-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88317736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
