摘要：

目的:考察强迫症患者在Stroop冲突任务中是否存在执行加工功能损害。方法:采用不一致任务占不同比例的3个Stroop干扰任务,任务1中不一致试次占30%,任务2中不一致试次占70%,任务3中不一致任务和一致任务分别占50%,27例强迫症患者和25例健康志愿者分别完成了Stroop干扰任务。结果:①在三种任务条件下均观察到了显著的Stroop干扰效应。②两组被试Stroop干扰任务的干扰量都随着任务条件水平的改变而改变。③两组被试之间的Stroop干扰量没有统计学差异。结论:强迫症患者可能不存在冲突任务执行加工方面的功能障碍。

Objective: To explore whether patients with obsessive-compulsive disorder (OCD) have executive dysfunc tion in conflictive tack. Methods: A new variant of high-conflict Stroop-color-word interference task with three different blocks was used in this study. In block one, incongruent trails take up 30 percent of total trails. In block two, incongruent trails occupy 70 percent. In block three, both incongruent and congruent trails take up 50 percent of the total trails. 27 patients who met CCMD-III criteria for obsessive-compulsive disorder and 25 healthy volunteers completed this task. Results: Both patients and controls observed interference effect, and the interference effect changed in different blocks. Conclusion: The current findings suggest that patients with obsessive-compulsive disorder have no executive dysfunction in high-conflict Stroop-color-word interference task.
