Feeling as if people are looking at self is a common theme of referential symptoms of patients with schizophrenia. Judging other's intention through gaze perception is a mentalization process. We report two studies to explore pattern of the self-referential gaze perception in patients with schizophrenia its relationship cognitive functions and clinical symptoms, stage of illness and specific eye movement pattern. We found that patients with psychotic symptoms have hypermentalization of gaze perception as towards oneself whereas patients with delusion of reference have more profound bias in gaze perception. Such bias present in both chronic or first-episode patients. Specific gaze pattern was identified while patients were judging the intent of the other's gaze in comparison with healthy control.
