唤醒度对情绪加工影响的相关研究进展

The research progress:The effect of arousal on emotional processing

情绪的维度理论认为,情绪效价和唤醒度是影响情绪加工的直接维度。一直以来,情绪加工的研究多集中在情绪效价上,往往忽视了唤醒度的重要性。但研究者逐渐发现唤醒度在情绪加工中起着重要的作用,甚至可能比情绪效价的影响程度更大。目前,部分研究结果分析了唤醒度在事件相关电位的作用,并探讨了唤醒度的情绪加工脑机制,但很多研究得出不一致的结论。而唤醒度与情绪记忆的增强效应关系确切,高唤醒度的刺激比低唤醒度的刺激记忆效果更好。也有研究揭示了唤醒度与动机之间关系密切,但现有的研究较少,还很难有一个确切的说法。

According to the dimension theory of emotion,valence and arousal are the direct dimensions that affect emotional processing.For a long time,the research on emotional processing has been focused on valence,and the importance of arousal is often neglected.But researchers are gradually discovering that arousal plays an important role in emotional processing,even more than valence.At present,some studies have analyzed the effect of arousal on event-related potential,and explored the emotional processing brain mechanism of arousal,but many studies have inconsistent conclusions.The relationship between arousal and emotion enhanced memory is accurate,and the effect of high arousal is better than that of low arousal.Other studies have revealed a close relationship between arousal and motivation,but there are few existing studies and it is hard to say for sure.
