The current study aimed to clarify the role of emotional intensity in vocal emotion decoding and its time course. Behavioral responses and electroencephalograms for vocalizations with different levels of emotional intensity were recorded while participants performed emotion identification on neutral-happy continua. It was found that the rates of happiness and P300 amplitudes increased as emotional intensity increased, whereas N100 and P200 components differed only between happy and neutral vocalizations. These findings suggest that emotional intensity is most likely decoded at a late stage of vocal emotion perception.
当前的研究旨在阐明情感强度在语音情感解码中的作用及其时间进程。在参与者对中性-快乐连续体进行情感识别时，记录了不同情感强度发声的行为反应和脑电图。研究发现，随着情感强度的增加，快乐识别率和P300波幅也增加，而N100和P200成分仅在快乐和中性发声之间存在差异。这些发现表明，情感强度很可能在语音情感感知的后期阶段被解码。
