目的：考察在安静状态下不同愤怒特质者对刺激的冲突控制是否存在差异。方法问卷调查法筛选低、高特质怒被试(低特质怒组，n=14；高特质怒组，n=16)，完成Stroop任务。采集被试行为数据和脑电数据，分析被试在一致刺激和不一致刺激下行为学及脑电潜伏期、波幅的差异。结果行为学结果中，两组被试一致及不一致刺激下的反应时及反应正确率比较，差异均无统计学意义(P>0.05)。脑电结果中，两组被试的N450峰潜伏期、波幅及差异波比较，差异无统计学意义(P>0.05)，虽然两组被试冲突性慢电位(SP)的峰潜伏期和波幅差异无统计学意义(P>0.05)，但SP差异波(不一致减一致)面积比较，差异有统计学意义(P<0.05)。结论对于不同愤怒特质者而言，其对冲突刺激的加工解决的脑激活程度没有显著的差异。但不同愤怒特质者对反应监控能力存在不同，低特质怒者在不一致刺激中投入的认知监控资源多于高特质怒者，对反应的监控较强。

Objective To observe the differences of conflict control between low- and high- trait anger group. Meth-ods The participants were assigned to high and low trait anger group (n =16, 14) by their STAXI-2 score. Behavioral data and ERPs data relevant to a visual Stroop task in high and low trait anger group were recorded and analyzed. Re-sults No significant differences were found in either reaction time or accuracy (P>0.05). No significant differences were found in the N450 of ERPs either (P> 0.05). Although, no significant differences were found in the peak latency and amplitude of conflict slow potential (SP) of participants in two groups (P> 0.05), the difference wave (incongruent mi-nus congruent) of conflict SP of ERPs showed a significant difference in the central-parietal regions (P<0.05). Con-clusion Although the N450 component is not modulated by the trait anger, the conflict SP component relevant to re-sponse monitoring is smaller in high than that in low trait anger group. These data implicate that the dysfunction of conflict control in high trait anger individuals.
