The present electrophysiological study investigated the processing of emotional prosody by minimizing as much as possible the effect of emotional information conveyed by the lexical-semantic context. Emotionally colored French vowels (i.e., happiness, sadness, fear, and neutral) were presented in a mismatch negativity (MMN) oddball paradigm. Both the MMN, i.e., an event-related potential (ERP) component thought to reflect preattentive change detection, and the P3a, i.e., an ERP marker of involuntary orientation of attention toward deviant stimuli, were significantly modulated by the emotional deviants compared to the neutral ones. Critically, the largest amplitude (MMN, P3a) and the shortest peak latency (MMN) were observed for fear deviants, all other things being equal. Taken together, the present findings lend support to a sequential neurocognitive model of emotion processing (Scherer, 2001) which postulates, among other checks, a first stage of automatic emotion detection (MMN) followed by a second stage of subjective evaluation of the stimulus or event (P3a). Consistently with previous studies, our data suggest that among the six universal emotions, fear could have a special status probably because of its adaptive role in the evolution of the human species.
本电生理研究通过尽可能减少词汇语义背景所传达的情感信息的影响，来探究情感韵律的处理过程。带有情感色彩的法语元音（即快乐、悲伤、恐惧和中性）在失匹配负波（MMN）奇偶数范式中呈现。与中性元音相比，情感偏离元音均显著调节了MMN（即一种被认为反映前注意变化检测的事件相关电位（ERP）成分）和P3a（即一种对偏离刺激的非自愿注意定向的ERP标记）。关键的是，在其他条件相同的情况下，恐惧偏离元音的MMN和P3a振幅最大，MMN的峰值潜伏期最短。综上所述，本研究结果支持了情感加工的顺序神经认知模型（Scherer，2001），该模型除其他检查外，假定了一个自动情感检测的第一阶段（MMN），随后是对刺激或事件进行主观评估的第二阶段（P3a）。与先前的研究一致，我们的数据表明，在六种普遍情感中，恐惧可能具有特殊地位，这可能是由于其在人类物种进化中的适应性作用。
