摘　　要：目的应用自我面孔识别(self face recognition,SFR)这种认知实验心理学范式探讨阳性与阴性症状精神分裂症患者的自我异常。方法应用自我面孔识别研究范式,对21例阳性症状、21例阴性症状为主的精神分裂症患者和21例正常被试进行行为学研究,并对结果进行分析。结果研究显示正常被试对自我图片的识别速度快于对陌生人图片的识别速度(P<0.05);以阴性症状为主的精神分裂症患者对陌生人图片的识别速度快于对自我图片的识别(P<0.05);以阳性症状为主的精神分裂症患者对不同图片的反应速度比较,差异没有统计学意义(P>0.05)。结论和正常被试相比,精神分裂症患者的自我面孔识别存在着异常,阳性症状和阴性症状的精神分裂症患者自我异常的表现差异有统计学意义(P<0.05)。Objective To investigate the self-disturbances of schizophrenia patients with positive and negative symptoms by using paradigm of self-face recognition（SFR）. Methods Twenty-one patients with schizophrenia with positive syndrome, 21 schizophrenia patients with negative syndrome and 21 normal controls matched in age and education degree were measured by self-face recognition procedure, and the results were analyzed. Results The healthy controls recognized one＇s own picture faster than strangers＇ picture;the patients with negative symptoms recognized stranger＇s pictures faster than their own ones（P〈0. 05）;there was no significant difference in the reacting time ratio on different pictures in patients with positive symptoms（P〉0. 05）.
