摘　　要：目的 考察对立违抗性障碍症状儿童的反应抑制能力.方法 被试为54名小学生,对立违抗性障碍症状组儿童和正常儿童各27名.试验采用停止信号任务、反应/不反应任务和西蒙任务.结果 对立违抗性障碍症状组儿童的停止信号延迟时间（SOA）、Go试验的平均反应时[分别为（260.27±69.12）ms,（554.31±55.81）ms],短于对照组[分别为（301.78±61.05）ms,（292.89±45.41）ms],差异有显著性（P＜0.05）.两组被试在反应/不反应任务和西蒙任务的表现,均差异无显著性（均P＞0.05）.结论 对立违抗性障碍症状组儿童的优势反应抑制能力较差,是其特征行为具有冲动性的内在加工机制.Objective To explore the response inhibition ability of oppositional defiant disorder symptoms children. Methods Subjects were 27 oppositional defiant disorder symptoms children and 27 normal children. They were asked to complete the stop signal task,go/no go task and the Simon task. Results The delay time of stop reaction （SOA,（260.27 ±69.12）ms） and go reaction time（ （554.31 ±55. 81 ）ms）of the oppositional defiant disorder symptoms children were shorter than the control group, the difference was significant （P〈0. 05）. However,the stop reaction and interference control ability were no significant difference between these two groups. Conclusion Oppositional Defiant Disorder symptoms children＇s poor prepotent response inhibition ability is cognitive mechanism of their impulsive behaviors.
