摘要： 运用事件相关电位（ERPs）技术，在双选择Oddball任务中考察了不同强度的回避性消极情绪对抑制功能的影响。结果发现，与中性条件下相比，被试在高回避性消极情绪下对偏差刺激的反应时延长，N2波幅更大，潜伏期更长，P3波幅更小，潜伏期更长；被试在低回避性消极情绪下反应时没有变化，P3波幅更小，潜伏期更长。这说明高、低回避性消极情绪对抑制功能的影响有差异：高回避性消极情绪在抑制加工的冲突监控及抑制实施过程中都表现出更大的干扰作用，低回避性消极情绪只在抑制实施阶段表现出干扰作用。

Abstract: The event-related potentials (ERPs) technique was used to examine the effect of avoidance motivational emotions on the inhibition function in the Oddball task. The results showed that the emotion of high avoidance motivational intensity impaired the inhibitory function, which prolonged the overall response time in Oddball task, and interfered inhibition function in the conflict monitoring stage (N2 amplitude was larger, the latency was longer) and inhibiting phase (P3 amplitude was smaller, the latency was longer); The emotion of low avoidance motivational intensity also impaired the inhibitory function, which interfered the inhibition function only in the inhibiting phase (P3 amplitude was smaller, the latency was longer). But there was no difference in the overall response time. The results suggest that the effects of high and low avoidance negative emotions on inhibition function are different, with high avoidance negative emotion showing greater interference in the whole process of conflict detection and inhibition.

Key words: avoidance motivational emotion, inhibition function, ERPs
