中文摘要：

应用Flanker研究范式探讨了正常成人被试在情绪冲突控制过程中的脑电特征。结果发现：干扰刺激的特征主要在P200上得到体现，判断刺激的特征主要在N300上得到体现，干扰刺激与判断刺激的特征体现了个体注意控制的过程。积极情绪和消极情绪在判断过程中发挥着不同的作用，但无论是作为干扰刺激还是作为判断刺激，消极情绪都使任务难度增大，对加工过程造成干扰；积极情绪则不然。

英文摘要：

ERP features were analyzed during the process of conflict emotion control in adults with the Flanker task. The results showed that a significant effect of disturb stimuli was found on in P200; the characteristic of target stimuli was shown in N300. The difference between disturb stimuli and target stimuli indicated the process in which the individual control led his attention. Positive and negative emotions showed different effects during the process of focusing attention, but negative emotion, as target stimuli or disturb stimuli, interefered with the cognitive process, but not the positive emotion.
