躁狂发作患者的自我面孔识别速度研究

摘要

目的 应用自我面孔识别这种认知实验心理学范式,探讨躁狂发作患者是否存在自我异常.方法 对32例符合DSM-IV诊断标准的躁狂发作患者以及32例在年龄、性别、受教育程度上相匹配的正常被试进行面孔识别测试并记录反应时；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),而躁狂发作患者在对各组图片的反应速度上差异无统计学意义(P＞0.05).结论 和正常被试相比,躁狂发作患者的自我面孔识别在反应速度上存在异常.%Objective To investigate self-abnormality in manic patients using the experimental psychological paradigm of self-face recognition(SFR). Methods Totally 32 manic patients who met the criteria of mania in DSM-Ⅳ and 32 healthy subjects matched in gender, age and education level were tested. The subjects were asked to recognize the face images presented on the computer, the data of the reaction times were recorded by the computer and were analyzed by Metlab and SPSS software. Results The manic patients showed slower responding time on recognizing pictures than the healthy controls. Healthy controls were faster in recognizing one' s own picture than strangers' picture(P<0.05); the manic patients showed no significant difference in recognizing all kinds of pictures(P>0. 05). Conclusion There was abnormality on self-face recognition in manic patients, compared to normal subjects.
