In the present study, we examined modulations of the second language (L2) positive emotion-label words, positive emotion-laden words, and neutral words on conflict processing in a flanker task. Twenty Chinese-English bilinguals were instructed to decide the color of the central words that were vertically surrounded by the same words with the same or different color. During the task, their cortical activation was recorded. The result showed that L2 positive emotion-laden words elicited different brain activations from emotion-label words and neutral words at both early and late stages. Differential modulations on conflict processing between positive emotion-label words and positive emotion-laden words in the L2 existed even after approach-motivation intensity was controlled. These results suggest emotion word type affects conflict processing, even in L2.
在本研究中，我们考察了第二语言（L2）中的积极情绪标签词、充满积极情绪的词汇以及中性词对侧翼任务中冲突处理的调节作用。二十名汉英双语者被要求判断中心词的颜色，中心词在垂直方向上被相同或不同颜色的相同词汇所包围。在任务过程中，记录他们的皮层激活情况。结果表明，L2中充满积极情绪的词汇在早期和晚期阶段均引发了与情绪标签词和中性词不同的大脑激活。即使在控制了趋近动机强度之后，L2中积极情绪标签词和充满积极情绪的词汇在冲突处理上仍存在差异调节。这些结果表明，即使在第二语言中，情绪词类型也会影响冲突处理。
