“…Note that the lack of correlation between these two component processes in the patients cannot be accounted for by insufficient statistical power or differences in stimuli, because both processes were correlated with self-face recognition. In addition, our finding is consistent with previous studies reporting that patients with schizophrenia are deficient in recognizing the familiarity of faces [19,[29][30][31][32]. On the other hand, no deficit in the sense of self in self-face recognition was found for the patients tested.…”

The concept of self is a fundamental characteristic of the human mind, and the alteration of self is thought to be a core deficit of schizophrenia. Previous studies have demonstrated that patients with schizophrenia are deficient in self-face recognition. Because self faces are not only self-related but also highly familiar, it is unclear whether such deficit arises from the breakdown of the self-awareness or the failure of recognizing the familiarity of self faces. Here we directly tested these two alternatives by instructing patients with schizophrenia to recognize the identity of a morphed face created by blending face features between any of two identities from the self face, a familiar face, and a novel face. We found that there was no association between the recognition of the self and the recognition of the familiarity, suggesting these two component processes are independent in schizophrenia. Further, patients with schizophrenia were significantly worse in recognizing the familiarity of faces than normal participants, whereas no difference in the sense of self was found between the two groups. Taken together, our finding suggests that it is the sense of familiarity, not the sense of self, that is selectively impaired in self-face recognition in schizophrenia. Thus, our study challenges the hypothesis that the deficit in self-face recognition in schizophrenia reflects the breakdown of self-awareness. , two related but distinct theories have been proposed. One interpretation is that the poor performance reflects deficits in recognizing the familiarity of self faces (i.e., a deficit in the sense of familiarity) [19,20], whereas the other argues that the disrupted behavior arises from the breakdown of self-awareness in schizophrenia (i.e., a deficit in the sense of self) [13,16]. To test these two alternatives, we adopted a paradigm to exclude the effect of general cognitive ability and to decouple self-face recognition into two component processes, the sense of familiarity and the sense of self. We then directly examined which component process of self-face recognition is disrupted in schizophrenia. Previous studies have shown that the sense of familiarity and the sense of self are processed independently in normal participants [9,11]. First, a left-hand advantage is observed only in recognizing self faces, not familiar faces, suggesting that the processing of self is dominated in the right hemisphere [4][5][6]. Second, functional magnetic resonance imaging studies have revealed that different cortical regions are

“…Most of these investigations have found that schizophrenia patients have defi-cits in both facial and vocal affect recognition (e.g. Archer et al, 1994;Baudouin et al, 2002;Borod et al, 1993;Edwards et al, 2001;Feinberg et al, 1986;Heimberg et al, 1992;Mandal et al, 1998;Penn et al, 2000;Schneider et al, 1995;Walker et al, 1984), and that these deficits are not related to age, gender, medication status or neuroleptic dose (Kline et al, 1992;Poole et al, 2000;Salem et al, 1996;Schneider et al, 1995).…”

“…7 While the capacity to remember socially relevant information may partly rely on the same memory systems involved in emotional memory, evidence also suggests that memory for social information relies on specific brain regions, including the dorsomedial prefrontal cortex (DMPFC). 8,9 It is now well known that patients with schizophrenia have difficulty processing social cues, [10][11][12] which likely contributes to social dysfunction. 13 Such a dysfunction is a hallmark characteristic of schizophrenia with important implications for the outcome of this illness.…”
