The aim of this study was to have a comparison among the schizophrenic patients with high positive symptoms and schizophrenic patients with low positive symptoms and normal individuals in negative priming effect test. The findings indicate that the main effect of negative priming and interaction effect of group*hemisphere are not significant. However, it indicates that there is a significant difference among the groups in terms of the extent of negative priming. These findings confirm the assumption that processing reaction time of negative priming in schizophrenia significantly differs with normal persons. Also it can be concluded that negative priming in schizophrenic patients in acute stage decreased comparing to the chronic patients and normal group. Findings are discussed based on changes in dopaminergic system.
