有证据表明，情绪在人脑中是超模态的。在真实的生活中，情绪面部表情往往先于言语表达的情绪，在情绪韵律加工过程中对事件相关电位（N100和P200）具有调制作用。为了研究这些跨通道的情绪互动，人们提出了两条研究路线：跨通道整合和跨通道启动。在跨通道整合研究中，视觉和听觉通道在时间上是对齐的，而在启动研究中，它们是连续呈现的。本研究采用跨通道情绪启动技术研究动态视听情绪信息的交互作用。具体来说，我们提出了动态的面部表情（愤怒，高兴，中性）作为启动和情感吟诵的伪语音句子（愤怒，高兴）作为目标。我们感兴趣的是启动靶一致性如何影响早期听觉事件相关电位，即，N100和P200，以便更多地了解动态面部信息如何用于跨模态情绪预测。结果表明，增强N100振幅的不一致性启动相比，一致性和中性启动的情绪韵律，而后两种情况下没有显着差异。然而，N100峰潜伏期显着延迟相比，其他两个条件下，在中性条件。源重建显示，在N100时间窗内，与一致性试验相比，不一致性试验激活了右侧海马旁回。在P200范围内未观察到显著的ERP效应。我们的研究结果表明，动态面部表情影响声乐情绪处理在早期的时间点，和面部表情和随之而来的声乐情绪信号之间的情感不匹配引起额外的处理成本在大脑中，可能是因为跨模态的情绪预测机制被违反的情况下，情绪启动目标不一致。
Evidence suggests that emotion is represented supramodally in the human brain. Emotional facial expressions, which often precede vocally expressed emotion in real life, can modulate event-related potentials (N100 and P200) during emotional prosody processing. To investigate these cross-modal emotional interactions, two lines of research have been put forward: cross-modal integration and cross-modal priming. In cross-modal integration studies, visual and auditory channels are temporally aligned, while in priming studies they are presented consecutively. Here we used cross-modal emotional priming to study the interaction of dynamic visual and auditory emotional information. Specifically, we presented dynamic facial expressions (angry, happy, neutral) as primes and emotionally-intoned pseudo-speech sentences (angry, happy) as targets. We were interested in how prime-target congruency would affect early auditory event-related potentials, i.e., N100 and P200, in order to shed more light on how dynamic facial information is used in cross-modal emotional prediction. Results showed enhanced N100 amplitudes for incongruently primed compared to congruently and neutrally primed emotional prosody, while the latter two conditions did not significantly differ. However, N100 peak latency was significantly delayed in the neutral condition compared to the other two conditions. Source reconstruction revealed that the right parahippocampal gyrus was activated in incongruent compared to congruent trials in the N100 time window. No significant ERP effects were observed in the P200 range. Our results indicate that dynamic facial expressions influence vocal emotion processing at an early point in time, and that an emotional mismatch between a facial expression and its ensuing vocal emotional signal induces additional processing costs in the brain, potentially because the cross-modal emotional prediction mechanism is violated in case of emotional prime-target incongruency.
