寻找丢失的自我——精神分裂症患者的自我面孔识别
摘要
<p id="C2">Self-face recognition of patients with schizophrenia has always been a controversial topic. Different opinions exist about whether patients with schizophrenia have the ability of self-face recognition. One theory holds that the ability to recognize one’s own face is impaired in patients with schizophrenia, whereas others assert that the ability to process one’s face is intact. The most recent studies on self-face recognition in patients with schizophrenia are only based on visual self-face recognition. Therefore, in addition to using self-face recognition of a single modality, the audiovisual integration task may become a new way to explore schizophrenics’ self-face recognition. <p id="C201">In the present study, 34 patients with schizophrenia and 26 participants without schizophrenia were assigned to complete a dynamic single-modality self-face recognition task, self-voice recognition task, and audiovisual integration task. Experiment 1 was a 2 (participant type: schizophrenic, participants without schizophrenia) × 3 (face type: self, same gender, opposite gender) within-groups design. Experiment 2 was a 2 (participant type: schizophrenic, participants without schizophrenia) × 3 (voice type: self, same gender, opposite gender) within-groups design. Experiment 3 was a 2 (participant type: schizophrenic, participants without schizophrenia) × 3 (face type: self, same gender, opposite gender) × 3 (voice type: self, same gender, opposite gender) within-groups design, which aimed to explore the influence of participants’ self-face recognition on voice recognition in the audiovisual integration task. <p id="C202">Results showed that: 1) There was no significant difference in self-face recognition between patients with schizophrenia and participants without schizophrenia, and patients with schizophrenia could recognize their faces; 2) In self-voice recognition, there was no significant difference between patients with schizophrenia and participants without schiz
