Abstract: It is commonly agreed that schizophrenia is associated with changes of self indicating that self disorders may be one of the core symptoms of schizophrenia, or at least accounting for clinical manifestation of schizophrenia. However, the underlying mechanism of self impairment in schizophrenia is still unclear. In this review, we would like to review the concept of self from perspectives of psychology, psychiatry and cognitive neuroscience. In particular, we would like to examine sense of agency, self-face recognition, and self-reference and how these constructs may related to schizophrenia. We hope that this review can provide insight on the evaluation of self impairment in schizophrenia.

Key words: self, schizophrenia, sense of agency, self-face recognition, self-reference process
