Results: The data were analyzed with regard to d´, β and attribution bias scores. This scores is accounted based on SDT statistical method. Relative to three other groups, schizophrenian patients who had experienced current auditory hallucination in visual version of source monitoring task had poorer performance in attribution bias scores than, that hasn’t attribute to the β scores and antipsychotic medication.
