词汇的唤醒度对情绪标注效应的影响—ERPs研究

基于晚期阻断理论考察词汇唤醒度对情绪标注效应的影响，研究选择情绪面孔图片为实验材料，借助ERPs技术，以命名后的LPP波幅为指标，考察词汇的唤醒度对情绪标注效应的影响。结果发现：进行情绪标注时，与使用低唤醒度词相比，高唤醒度词条件下的LPP波幅更小；而进行非情绪标注时，差异不显著；无论词的唤醒度高或低，情绪标注与非情绪标注差异显著，情绪标注下LPP波幅更低。结果表明：进行情绪标注时，情绪词唤醒度越高抑制情绪的效果越好，而进行非情绪标注时则无影响；结果支持了晚期阻断理论。

Effects of Arousal of Vocabulary on Affect Labeling: An ERPs Study

Based on the disruption theory, the present research conducted an ERP experiment to investigate the effect of the words with different arousal on affect labeling and gender labeling. Given the previous studies, the dependent variable was the late positive potential (LPP) after the affect/gender labeling and negative emotional faces as experimental materials was used. The results showed that the amplitude of LPP was lower especially at the Pz electrode point, when the labels of affect labeling were high arousal words; but the amplitude of LPP had no difference when the labels of gender labeling with different arousal words. In addition, no matter how the arousal of the words was, the difference between affect labeling and gender labeling was significant, and the amplitude of LPP was lower on affect labeling. The results indicate that the higher the arousal of affect labeling words, the better the inhibition effect of emotion; however, the gender labeling can not suppress emotion. The disruption theory has been further confirmed.
