摘　　要：目的应用自我面孔识别这种认知实验心理学范式,探讨抑郁症患者是否存在自我异常。方法对16例符合DSM-IV诊断标准的抑郁症患者以及16例在年龄、性别、受教育程度上相匹配的正常被试进行头像采集,并使用Photoshop、Morph工具处理并合成面孔,使用Presentation心理学软件请被试进行面孔识别并记录反应时;使用Metlab及SPSS工具分析将所得数据进行分析比较。结果对实验所得数据进行重复测量方差分析结果发现,抑郁症患者在识别自我图片的反应速度上较健康被试反应慢,差异有统计学意义(P<0.05)。在识别陌生人图片的反应速度上,抑郁症患者和健康被试间比较,差异无统计学意义(P>0.05)。而在名人图片的反应速度上,抑郁症患者的右手对名人图片的反应速度较正常被试慢(P<0.05),而左手差异无统计学意义(P>0.05)。结论抑郁症患者的自我面孔识别在反应速度上存在异常。Objective To investigate self-abnormality of depression patients using the experimental psychology paradigm of self-face recognition（SFR）. Methods We used the Photoshop, Murph image processing technology to prepare the face images of 16 patients with depression who met the criteria of the DSM-Ⅳ and 16 normal subjects with matched gender, age and education level. The subjects were asked to recognize the face images presented on a computer, the data of the response times recorded by the computer were analyzed by Metlab and SPSS software. Results In the self face images recognition, the patients with depression were slower than that of the healthy subjects（P〈0. 05）. In the stranger images recognition, there were no statistically significant differences between depression patients and healthy subjects （P〉0.05）. And in the famous images recognition, the right hands of depression patients reacted slower than normal subjects （P〈0. 05）, and left no statistical difference （P〉0.05）. Conclusion The result indicated that depression patients had self-abnormality.
