Music- and distraction-induced pain reduction have been investigated extensively, yet the main mechanism underlying music-induced analgesia remains unknown. In this study, to assess whether music-induced analgesia primarily operates through cognitive modulation, we used the cold pressor task and objectively compared the pain tolerances of participants in a four-group between-subjects design: a music group that listened to a music piece in the absence of any tasks, a music-and-attention-to-music group that listened to the same piece while also rating the arousal levels in the music, a music-and-attention-to-pain group that rated their pain levels while listening to the same piece, and a silence group as control. The group passively exposed to music playback did not show significantly higher pain tolerance compared to the silence group. However, pain tolerances in the music group negatively correlated with participants' self-reported arousal ratings of the music at the end of the experiment. The groups that engaged in an active task - whether evaluating the arousal levels in the music or reporting their experienced pain levels - demonstrated similarly higher pain tolerances compared to the silence group. These findings suggest that engaging in a task, regardless of whether it involves exteroceptive or interoceptive attention, can enhance pain tolerance.
音乐和分心诱导的疼痛减轻已得到广泛研究，但音乐诱导镇痛的主要机制仍不清楚。在本研究中，为评估音乐诱导镇痛是否主要通过认知调节起作用，我们使用冷加压任务，并在一项四组组间设计中客观比较了参与者的疼痛耐受性：一个在无任何任务情况下听一段音乐的音乐组；一个在听同一首音乐的同时对音乐中的唤醒水平进行评分的音乐与关注音乐组；一个在听同一首音乐时对自身疼痛水平进行评分的音乐与关注疼痛组；以及一个作为对照的安静组。与安静组相比，被动听音乐播放的组并未表现出显著更高的疼痛耐受性。然而，在实验结束时，音乐组的疼痛耐受性与参与者自我报告的音乐唤醒评分呈负相关。与安静组相比，参与主动任务的组——无论是评估音乐中的唤醒水平还是报告他们所体验到的疼痛水平——都表现出类似的更高的疼痛耐受性。这些发现表明，从事一项任务，无论它涉及外感受性还是内感受性注意，都可以提高疼痛耐受性。
