While the reasons underlying musical emotions are unclear, music is nevertheless a powerful elicitor of emotion, and as such, may induce autonomic nervous system responses. One typical measure of this neural pathway is the skin conductance response (SCR). This response generally depends upon stimulus arousal, one of the two motivational determinants of emotion. The objective of the present study was to verify whether emotional reactions to music elicit such event-related autonomic responses. To this aim, four musical emotions varying in arousal were employed: fear, happiness, sadness and peacefulness. SCRs were found to be greater with the two more stimulating emotions, fear and happiness, as compared to the two more relaxing emotions, sadness and peacefulness (P<0.05). In addition, subjects' ratings of the emotional clarity for each excerpt did not parallel the corresponding SCRs magnitudes. The results show that SCRs can be evoked and modulated by musical emotional arousal, but are not sensitive to emotional clarity. While several studies have been performed with visual scenes and environmental sounds, the present study brings similar evidence from the musical domain.
虽然音乐情感背后的原因尚不清楚，但音乐仍然是一种强大的情感激发因素，因此可能会引发自主神经系统的反应。这种神经通路的一种典型测量方法是皮肤电导率反应（SCR）。这种反应通常取决于刺激唤起，它是情感的两个动机决定因素之一。本研究的目的是验证对音乐的情感反应是否会引发这种与事件相关的自主反应。为此，采用了四种唤起程度不同的音乐情感：恐惧、快乐、悲伤和宁静。结果发现，与悲伤和宁静这两种较为舒缓的情感相比，恐惧和快乐这两种更具刺激性的情感所引发的皮肤电导率反应更大（P<0.05）。此外，受试者对每个音乐片段情感清晰度的评分与相应的皮肤电导率反应大小并不平行。结果表明，皮肤电导率反应可由音乐情感唤起所诱发和调节，但对情感清晰度不敏感。虽然已经针对视觉场景和环境声音进行了多项研究，但本研究从音乐领域提供了类似的证据。
