Methods: Two groups – 40 39 subjects were compared. In source monitoring task, performed simple computer mouse movements evaluated partially manipulated visual feedback either self- or other-generated. second step, participants indicated confidence their decision 4-point rating scale. an emotion-recognition had to identify 6 basic emotions prosody spoken sentences. ‘reading-the-mind-in-the-eyes’ test, infer mental states from pictures that depicted others’ eyes. attribution presented with descriptions events asked attribute cause event person, object situation. Additionally, all tested for cognitive functioning levels. Results: The patient significantly worse tasks than control group. Correlation analysis showed related deficits person lower levels task. Also, higher PANSS positive scores number hospitalizations. Stepwise regression revealed explained 48.0% variance ego-disturbance score represented best predictors disturbances. One particular variable, namely hospitalizations, additionally 13.8% variance. Conclusion: Our findings suggest are domain, and, lesser extent, such
