自我相关性影响情绪词汇加工的时间进程

在社会交往中,判断情绪刺激与自我和他人的相关程度对于情绪加工十分重要。本研究利用ERPs技术,要求被试默读相继呈现的名字(自我、朋友和陌生人)和情绪性词汇(积极、中性和消极),考察自我相关信息影响情绪词汇加工的动态时间特征及二者的整合机制。结果发现,在情绪词汇加工早期,消极词汇相比积极和中性词汇诱发了波幅更大的EPN。在加工晚期,消极词汇相比中性词汇诱发波幅更小的N400,并相对中性和积极词汇诱发更大的LPP。更为重要的是,在LPP时间窗出现情绪效价和自我相关性的交互作用:与自我名字相关的消极词汇比中性词汇诱发了波幅更大的LPP,与朋友名字相关的消极词汇比中性和积极词汇诱发了波幅更大的LPP,而与陌生名字相关的各类词汇诱发的LPP波幅无显著差异。该研究表明,个体对情绪信息非常敏感,随着加工的深入会体现出不同的认知过程,并且会根据自我相关性进行过滤,在加工晚期与自我相关信息进行整合,表现出自我和朋友相关的消极情绪的加工优势。

The time course of self-relevance affecting emotional word processing

In successful social interactions, distinguishing between our own and another person's emotions is important. For individuals, both self-related information (such as self-name) and emotional stimuli with high sociality or adaptive meaning can automatically capture one's attention, leading to prior and deep processing. Previous studies have confirmed that self-relevance can affect the processing of emotional words. However, there is currently no research using name as a self-relevance clue to investigate whether and how name influences the cognitive processing of emotional words. In the current study, we used names as self-relevance clues to explore the dynamic temporal characteristics of self-related information affecting emotional information and its integration mechanism.
