The present study examined music-induced dopamine release, as measured by a proxy measure of spontaneous eye blinks. Specifically, we explored the effects of uplifting and sombre tones in different sections of Vivaldi's to investigate the affective content of musical pieces within one composition. Seventeen participants listened to four concertos (Major modes: "Spring" and "Autumn", Minor modes: "Summer" and "Winter") and a silence condition while completing a three-stimulus odd-ball attention task. Electrooculograms were recorded from electrodes placed above and under the left eye. Self-reported arousal and music preference measures were also gathered during the testing session. In addition, the P3a Event-Related Potential (ERP) component was analysed as another potential index of dopamine function. Results revealed significant differences in the blink rates during music listening and silence, with the largest effect observed for the sad, melancholic "Winter" concerto. However, no significant correlation was found between blink rate and music preference or arousal. Furthermore, no reliable association was found between blink rate and the P3a ERP component, suggesting that these measures tap into different aspects of dopamine function. These findings contribute to understanding the link between dopamine and blink rate, particularly in response to classical music. Crucially, the study's discovery that the "Winter" concerto, with its sorrowful tone, significantly increased the blink rate highlights the significance of sad music and perhaps the programmatic qualities of this concerto to induce a strong emotional response.
本研究通过对自发眨眼这一替代指标的测量，考察了音乐诱发的多巴胺释放情况。具体而言，我们探究了维瓦尔第作品不同乐章中欢快和忧郁音调的效果，以研究同一部作品中不同乐章的情感内涵。17名参与者在完成一项三刺激odd-ball注意力任务的同时，聆听了四首协奏曲（大调模式：《春》和《秋》，小调模式：《夏》和《冬》）以及一个安静条件。从放置在左眼上方和下方的电极记录眼电图。在测试过程中还收集了自我报告的唤醒水平和音乐偏好测量数据。此外，对P3a事件相关电位（ERP）成分进行了分析，作为多巴胺功能的另一个潜在指标。结果显示，在聆听音乐和安静状态下的眨眼频率存在显著差异，悲伤忧郁的《冬》协奏曲产生的影响最大。然而，眨眼频率与音乐偏好或唤醒水平之间未发现显著相关性。此外，眨眼频率与P3a ERP成分之间也未发现可靠的关联，这表明这些测量指标反映了多巴胺功能的不同方面。这些发现有助于理解多巴胺与眨眼频率之间的联系，尤其是对古典音乐的反应。至关重要的是，该研究发现，音调悲伤的《冬》协奏曲显著提高了眨眼频率，这突出了悲伤音乐的重要性，或许也凸显了这首协奏曲的标题音乐特质能够引发强烈的情感反应。
