精神分裂症自知力和自我面孔识别速度的关系

Relationship between Speed of Self-face Recognition and Insight in Patients with Schizophrenia

目的应用自我面孔识别这一实验心理学范式探讨精神分裂症自知力与自我的关系。方法对12例无自知力、12例有自知力的男性精神分裂症患者以及在年龄、受教育程度上相匹配的12例男性正常被试者进行自我面孔识别的测查,并分析结果。结果正常被试者对自我图片识别速度快于识别陌生人图片(P<0.05),但是与名人图片识别速度差异无统计学意义(P>0.05);有、无自知力的精神分裂症患者均未表现出对自我-陌生人图片识别速度上的自我识别优势(P>0.05),无自知力患者组对自我图片的识别速度明显慢于对陌生人图片的识别(P<0.05);在自我面孔识别速度上有、无自知力的精神分裂症患者间差异有统计学意义(P<0.05),而在陌生人和名人识别速度上差异无统计学意义(P>0.05)。结论精神分裂症患者的自我存在异常;其自知力与自我面孔识别有一定关系。

Objective To investigate the relationship between insight and self-awareness of patients with schizophrenia using paradigm of self-face recognition（SFR）. Methods 12 schizophrenic patients with insight, 12 schizophrenic patients without insight and 12 healthy volunteer as control matched with age and education degree were measured by SFR, and the results were analyzed. Results The normal controls recognized their own face more quickly than the stranger＇ s （ P 〈 0.05 ） , and there was no difference between self face and famous face（ P 〉 0.05） ; however, there was no difference between self face and stranger＇ s face in schizophrenic patients （ P 〉 0.05 ）, and patients without insight recognize their own face more slowly（ P 〈0.05 ） ; there was difference in speed of self-face recognition between patients with and without insight （P 〈 0.05 ）, but no difference was found in stranger＇ s face and famous face recognition （P 〉 0.05）. Conclusion The results indicated that schizophrenic patients had self-disturbance, and insight might correlate with self-face recognition.
