“…It is interesting to note that the paper we published (Platek and Gallup [ 12 ]) on self-face reaction time latencies, which showed that normal subjects had a left-hand self-face reaction time advantage and that this phenomenon was reversed for subjects with premorbid schizophrenic-like tendencies (i.e., had high scores on the SPQ), generated considerable interest among researchers interested in schizophrenia and inspired several other articles. The majority of these articles, eight in addition to our own (Platek and Gallup [ 12 ], Platek et al [ 13 ], Platek et al [ 14 ], Bortolon et al [ 15 ], Jia et al [ 16 ], Garcia-Alverez et al [ 17 ], Klein et al [ 18 ], Heinishch et al [ 19 ], Pauly et al [ 20 ]), report results that were consistent with our findings, while five papers (Veluw et al [ 21 ], Kochs et al [ 22 ], Bortolon et al [ 23 ], Bortolon et al [ 24 ], Zhang et al [ 25 ]) either failed to find an effect or obtained results that were contrary to our findings.…”

In this article, we detail the advantages of self-face identification latencies over more traditional tests of mirror self-recognition. Using reaction time latencies (measured in milliseconds) to identify different dimensions of the self, instead of relying on a simple dichotomous pass/fail mirror mark-test outcome, enables investigators to examine individual differences in self-processing time. This is a significant methodological step forward with important implications. The point of departure for our article is to detail research we and others have conducted on latencies for self-face identification, to show how self-processing occurs in the right side of the brain, how schizophrenia is a self-processing disorder, how self-face reaction time latencies implicate the existence of an underlying multiple modal self-processing system, and to explore ideas for future research.

Self-experience impairments have been described since many years as part of core features of schizophrenia, but are currently neglected in research and clinical practice. First, a literature review on self-consciousness is developed in this article with regard to definitions (including the concepts of self and self-consciousness) and different approaches (especially cognitive, developmental and neurobiological approaches). Self-consciousness can be divided into three levels: minimal-self with implicit pre-reflexive consciousness, reflexive-self with explicit reflexive consciousness (consciousness of a permanent self as an invariant over time through multiple experiences and actions), and social-self (style, habits, and historical narrativity) with explicit self-consciousness. These levels appear progressively in the child from bodily perception (pre-reflexive consciousness) to identification of the self in the mirror at approximatively two-years old (reflexive consciousness) and appearance of mental representations later (self-consciousness). Second, self-consciousness impairments observed in schizophrenia are described in this article and discussed in light of the literature presented. Converging evidence suggests that exploring self-disorders in schizophrenia could help clinicians to understand daily-life patients difficulties and might be of interest for developing a therapeutic alliance. Finally, this critical literature review opens new perspectives to understand better disorders of the self and social interaction impairments in schizophrenia, and to propose a therapeutic use of the mirror based on cognitive remediation helping individuals with schizophrenia to improve self-other differentiation.

“…For example, some behavior studies applying visual search task, in which participants were instructed to detect a target (i.e., self-face) among distractors (i.e., distractor face images) in sets of two, four or eight faces, have investigated self-face recognition in vision domain. Results have found that altered visual self-recognition in people with SZ (Bortolon et al, 2016;Lee et al, 2007). Numerous neurophysiological studies have also found abnormalities in anatomical structures and functional activities related to face-processing (Lee et al, 2002;She et al, 2017).…”

Altered Auditory Self-recognition in People with Schizophrenia

Self-recognition is of great significance to our sense of self. To date, disturbances in the processing of visual self-recognition are well studied in people with schizophrenia, whereas relatively few studies have focused on the processing of self in other domains, such as auditory. An investigation of auditory self-recognition contributes to delineate changes related to self and the potential roots of the described psychopathological aspects connoting schizophrenia. By applying unimodal task and multisensory test, this study investigated auditory self-recognition in people with schizophrenia under unimodal and bimodal circumstances. Forty-six adults diagnosed with schizophrenia and thirty-two healthy controls were involved in this study. Results suggested that people with schizophrenia seemed to have significantly lower perceptual sensitivity in detecting self-voice, and also showed stricter judgment criteria in self-voice decision. Furthermore, in the presentation of stimuli that combined the stimulation of others’ faces with one’s own voice, people with schizophrenia mistakenly attributed the voices of others as their own. In conclusion, altered auditory self-recognition in people with schizophrenia was found.
