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.

精神分裂症患者听觉自我认知的改变

自我认知对我们的自我意识具有重要意义。迄今为止，在精神分裂症患者中对视觉自我识别处理的障碍进行了很好的研究，而相对较少的研究集中在其他领域的自我处理，例如听觉。对听觉自我识别的调查有助于描绘与自我相关的变化以及所描述的精神病理学方面的潜在根源，这些方面意味着精神分裂症。通过应用单峰任务和多感官测试，本研究调查了精神分裂症患者在单峰和双峰情况下的听觉自我识别。46 名被诊断患有精神分裂症的成年人和 32 名健康对照者参与了这项研究。结果表明，精神分裂症患者在检测自我声音方面的感知敏感性似乎显着降低，并且在自我声音决策中表现出更严格的判断标准。此外，在将他人面部的刺激与自己的声音相结合的刺激呈现中，精神分裂症患者错误地将他人的声音归因于自己的声音。总之，发现精神分裂症患者的听觉自我识别发生了改变。
