面部表情和语调都代表了情感交流的关键信号，但它们的大脑处理相关性仍不清楚。因此，我们构建了一个新的内隐情绪识别任务，包括同时呈现的人脸和声音与中性，高兴，愤怒的效价，在识别猴子的面孔和声音的任务。为了研究人的面孔-声音配对中情感信息加工的时间演变过程，我们记录了18名正常健康受试者对这些视听测试刺激的事件相关电位（ERP）;在额中央区电极上观察到N100、P200、N250、P300成分，而在额中央区电极上观察到P100、N170、在顶枕区电极上观察到P270。结果表明，视听刺激对额中央成分（P200、P300和N250）的波幅和波幅有显著影响，而对顶枕区成分（P100、N170和P270）的波幅和波幅无显著影响。具体而言，P200和P300振幅更积极的情绪相对于中性视听刺激，不考虑效价，而N250振幅是更消极的中性相对于情绪刺激。在愤怒和快乐的条件之间没有观察到区别。结果表明，尽管存在内隐情感加工任务的要求，但情绪对视听加工的一般影响最早可在刺激起始后200 msec（P200峰潜伏期）出现，且这种影响主要分布在额中央区。
Both facial expression and tone of voice represent key signals of emotional communication but their brain processing correlates remain unclear. Accordingly, we constructed a novel implicit emotion recognition task consisting of simultaneously presented human faces and voices with neutral, happy, and angry valence, within the context of recognizing monkey faces and voices task. To investigate the temporal unfolding of the processing of affective information from human face-voice pairings, we recorded event-related potentials (ERPs) to these audiovisual test stimuli in 18 normal healthy subjects; N100, P200, N250, P300 components were observed at electrodes in the frontal-central region, while P100, N170, P270 were observed at electrodes in the parietal-occipital region. Results indicated a significant audiovisual stimulus effect on the amplitudes and latencies of components in frontal-central (P200, P300, and N250) but not the parietal occipital region (P100, N170 and P270). Specifically, P200 and P300 amplitudes were more positive for emotional relative to neutral audiovisual stimuli, irrespective of valence, whereas N250 amplitude was more negative for neutral relative to emotional stimuli. No differentiation was observed between angry and happy conditions. The results suggest that the general effect of emotion on audiovisual processing can emerge as early as 200 msec (P200 peak latency) post stimulus onset, in spite of implicit affective processing task demands, and that such effect is mainly distributed in the frontal-central region.
