目的:应用情绪启动范式考察抑郁症患者情绪冲突的异常.方法:对20例抑郁症患者和18名在年龄、受教育程度等方面相匹配的对照组,进行了情绪启动实验,启动刺激为积极词、一般消极词和抑郁相关词,目标刺激为积极和消极人脸,要求判断人脸的情绪类型.还对所有被试进行了贝克抑郁问卷(BDI)和状态-特质焦虑问卷(STAT)的测查.结果:在抑郁组和对照组均发现了显著的一般情绪冲突效应(由一般消极词导致);在抑郁组身上还发现,当目标人脸为积极表情时,由抑郁相关词导致的特殊情绪冲突效应,显著大于一般消极词导致的情绪冲突效应,而这种差异在正常控制组身上却没有发现.回归分析的结果进一步表明,抑郁相关词导致的情绪冲突效应与BDI分数具有线性相关关系.结论:抑郁症患者在情绪冲突上不同于正常人的异常表现,可能跟他们的注意偏向有关.“,”Objective: To investigate the emotional conflict in patients with major depressive disorder (MDD) by an affective priming paradigm. Methods: 20 depressed patients and 18 matched normal controls were measured. The prime stimuli were positive, negative or depression-related words, and the target stimuli were positive or negative faces. The subjects were asked to judge whether the target expressions were positive or negative. Results: The general emotional conflict effects induced by the negative words were found in both depressed patients and controls. When the target faces were positively valeneed, the emotional conflict effects induced by the depression-related words were significantly greater than that induced by the negative words in depressed patients, while such difference did not occur in normal controls. Furthermore, the regression analysis identified a significant linear relationship between the depression-related emotional conflict effects and the BDI scores. Conclusion: The abnormal emotional conflict in depressed patients may be due to the attentional bias to the depression-related information.
