Altered auditory self-recognition in people with schizophrenia

ABSTRACT

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
