为了了解情绪状态如何影响听者对语音的生理反应，受试者观看情绪唤起图片，同时收集32通道EEG诱发反应（ERP）对不变的听觉刺激（“丹尼”）。这些图片选自国际情感图片系统数据库。参与者对它们进行了评价，并且在效价（积极，消极，中性）上有所不同，但在主导和唤醒方面没有差异。观看负面情绪图片的影响早在20毫秒（p = 0.006）。对全局场功率的分析突出了感兴趣的时间段（30.4-129.0毫秒），其中情绪的影响可能是最鲁棒的。在皮层水平上，反应显着不同的受试者提供的视觉刺激，其中分为高效价强度组和低效价强度组的效价等级。高效价强度组在感兴趣的时间区域表现出明显的情绪发散二价效应（从观看正面或负面图片期间的ERP中减去观看中性图片期间Cz处的ERP）（rΦ = 0.534，p <0.01）。此外，在这段时间内，群体差异出现在全球激活模式中。尽管两组都表现出情绪的显著影响（ANOVA，p = 0.004和0.006，分别为低价强度和高价强度），但高价强度组表现出更大的影响。而低效价强度组主要在额叶区域表现出较小的影响，在高效价强度组中发现了较大的影响，尤其是在左颞区，在中线周围的高效价强度受试者中具有最大的二价差异效应（ANOVA，p < .00001）。因此，不同的二价效应之间观察到30和130毫秒，并依赖于受试者的主观状态，而在20毫秒的影响是明显的，只有负面情绪，独立的受试者的行为反应。综上所述，情绪似乎可以在感觉处理流的早期影响听觉功能。
In order to understand how emotional state influences the listener’s physiological response to speech, subjects looked at emotion-evoking pictures while 32-channel EEG evoked responses (ERPs) to an unchanging auditory stimulus (“danny”) were collected. The pictures were selected from the International Affective Picture System database. They were rated by participants and differed in valence (positive, negative, neutral), but not in dominance and arousal. Effects of viewing negative emotion pictures were seen as early as 20 msec (p = .006). An analysis of the global field power highlighted a time period of interest (30.4–129.0 msec) where the effects of emotion are likely to be the most robust. At the cortical level, the responses differed significantly depending on the valence ratings the subjects provided for the visual stimuli, which divided them into the high valence intensity group and the low valence intensity group. The high valence intensity group exhibited a clear divergent bivalent effect of emotion (ERPs at Cz during viewing neutral pictures subtracted from ERPs during viewing positive or negative pictures) in the time region of interest (rΦ = .534, p < .01). Moreover, group differences emerged in the pattern of global activation during this time period. Although both groups demonstrated a significant effect of emotion (ANOVA, p = .004 and .006, low valence intensity and high valence intensity, respectively), the high valence intensity group exhibited a much larger effect. Whereas the low valence intensity group exhibited its smaller effect predominantly in frontal areas, the larger effect in the high valence intensity group was found globally, especially in the left temporal areas, with the largest divergent bivalent effects (ANOVA, p < .00001) in high valence intensity subjects around the midline. Thus, divergent bivalent effects were observed between 30 and 130 msec, and were dependent on the subject’s subjective state, whereas the effects at 20 msec were evident only for negative emotion, independent of the subject’s behavioral responses. Taken together, it appears that emotion can affect auditory function early in the sensory processing stream.
