Awe is a complex emotion that encompasses conflicting affective feelings inherent to its key appraisals, but it has been studied as either a positive or a negative emotion, which has made its ambivalent nature underexplored. To address whether and how awe's ambivalent affect is represented both behaviorally and neurologically, we conducted a study using virtual reality (VR) and electroencephalography (N = 43). Behaviorally, the subjective ratings of awe intensity for VR clips were accurately predicted by the duration and intensity of ambivalent feelings. In the electrophysiological analysis, we identified a latent neural-feeling space for each participant that shared valence representations across individuals and stimuli, using deep representational learning and decoding analyses. Within these spaces, ambivalent feelings were represented as spatially distinct from positive and negative ones, with large individual differences in their separation. Notably, this variability significantly predicted subjective awe ratings. Lastly, hidden Markov modeling revealed that the multiple band powers, particularly in the frontoparietal channels, were significantly associated with differentiation of valent states during awe-inducing VR watching. Our findings consistently highlight the salience of ambivalent affect in the subjective experience of awe at both behavioral and neural levels. This work provides a nuanced framework for understanding the complexity of human emotions with implications for affective neuroscience.
敬畏是一种复杂的情绪,它包含了其关键评估中固有的相互冲突的情感感受,但它一直被作为一种积极或消极情绪进行研究,这使得其矛盾的本质未得到充分探索。为了探讨敬畏的矛盾情感在行为和神经层面上是否以及如何表现,我们使用虚拟现实(VR)和脑电图进行了一项研究(N = 43)。在行为上,VR片段的敬畏强度主观评分可以通过矛盾情感的持续时间和强度准确预测。在电生理分析中,我们使用深度表征学习和解码分析,为每个参与者确定了一个潜在的神经情感空间,该空间在个体和刺激之间共享效价表征。在这些空间中,矛盾情感在空间上与积极和消极情感不同,其分离存在很大的个体差异。值得注意的是,这种变异性显著预测了主观敬畏评分。最后,隐马尔可夫模型显示,多个频段功率,特别是额顶叶通道中的频段功率,与观看引发敬畏的VR时价态的分化显著相关。我们的研究结果一致强调了矛盾情感在敬畏主观体验中的行为和神经层面的显著性。这项工作为理解人类情绪的复杂性提供了一个细致入微的框架,对情感神经科学具有启示意义。
