摘　　要：目的:使用事件相关电位(ERPs)考察边缘性人格障碍患者的情绪抑制功能是否存在缺陷。方法:采集34名边缘性人格障碍患者和27名正常对照组被试在完成改良版情绪Stroop任务时的ERPs数据。采用重复测量方差分析比较两组在行为学数据(反应时、正确率)和ERPs成分(P2和晚期正成分LPP)上的差异。结果:方差分析结果显示,两组被试在正确率和反应时上均不存在显著性差异。在ERPs方面,组间存显著性差异,边缘性人格障碍的P2和LPP的波幅均显著低于正常对照组的波幅,进一步分析显示边缘性人格障碍组的LPP波幅在负性情绪刺激条件下显著低于中性条件,而正常对照组不存在这种效应。结论:边缘性人格障碍患者的情绪抑制功能存在缺陷,且对于负性情绪刺激的抑制缺陷更明显。Objective： To examine the dysfunction of emotional inhibition in patients with Borderline Personality Disor- der（BPD）. Methods： A sample of 34 BPD patients and 27 healthy controls completed the modified Emotional Stroop task and the Event Related Potentials（ERPs） were recorded. Repeated measures ANOVA were used to analyze the differences between BPD group and control group on behavioral data（accuracy and reaction time） and ERP amplitude. Results： There were no significant group differences on behavioral data. There were significant group differences on amplitudes of P2 and Late Positive Potential（LPP）. BPD patients had lower P2/LPP amplitudes than those of healthy controls. BPD patients also had lower LPP amplitude at negative condition than that at neural condition. Conclusion： Patients with BPD have dysfunction in emotional inhibition, especially for negative emotion.
