中文摘要： 面孔、语音情绪整合加工是社会交往的重要技能，近年来逐渐引起心理学、神经科学研究的关注。当前研究较为系统地考察了双通道情绪整合的行为表现和影响因素，也很好地回答了"何时整合"与"在哪里整合"两个认知神经科学关注的问题，但对"面孔、语音情绪整合是否遵循一般感觉整合的核心规则--颠倒效应规则（the principal of inverse effectiveness）？双通道情绪信息在大脑中如何整合为一？"两个关键问题都还缺乏系统研究。因此，本项目用动态面孔-语音刺激为实验材料，以考察面孔、语音情绪整合是否遵循颠倒效应规则为主线设计了六个实验，系统操纵面孔、语音刺激的情绪凸显度和任务要求，采集行为和脑电数据。然后从多角度对行为、脑电数据进行分析，特别是神经振荡（时频、相干）分析，系统考察动态性面孔、语音情绪整合是否遵循颠倒效应规则，并说明双通道情绪信息在神经振荡层面如何整合。

英文摘要： The integration of facial-vocal emotion is an important factor for successful communication that intrigue psychologists and neuroscientists in recent years. Previous studies have elaborated on the behavioral performance and the influence factors for facial-vocal emotion integration, as well as "when" and "where" information from the two modes integrated. However, It remains open questions whether the integration of facial-vocal emotion follows the principles of multisensory integration (eg.the principle of inverse effectiveness),and how the bimodal emotional information merges into a coherence emotional object. Therefore,taking "whether facial-vocal emotion integartion obeys the principle of inverse effectiveness" as main line, we designed six experiments which manipulated emotional salience of the dynamic facial-vocal emotional stimuli and task demands systematically. Moreover, using multi-dimentional analysis of behavioral and EEG data, expacially time-frequency and coherence analysis of EEG data, we aimed to answer the two proposed questions, to further reveal the neurophysiological mechanism of facial-vocal emotion integration.
