Sound perception extends beyond the boundaries of auditory sensation, encompassing an engagement with the human body. In this study, we examined the relationship between our perception of sound pitch and our bodily sensations, while also exploring the role of emotions in shaping this intriguing cross-modal correspondence. We also compared the topography of pitch-triggered body sensations between depressive and non-depressive groups, and between alexithymic, and non-alexithymic groups. Further, we examined their associations with anxiety. Our findings reveal that individuals with alexithymic trait and depressive state experience a less localized body sensations in response to sound pitch, accompanied by heightened feelings of anxiety and negative emotions. These findings suggest that diffuse bodily sensations in response to sound may be associated with heightened feelings of anxiety. Monitoring pitch-triggered body sensations could therefore serve as a potential indicator of emotional tendencies linked to disorders such as depression and alexithymia. Our study sheds light on the importance of bodily sensation in response to sounds, a phenomenon that may be mediated by interoception. This research enhances our understanding of the intricate relationship between sound, emotions, and the human body, offering insights for potential interventions in emotional disorders.
声音感知超越了听觉感受的范畴，涵盖了与人体的关联。在本研究中，我们考察了音高感知与身体感觉之间的关系，同时探究了情绪在塑造这种有趣的跨模态对应关系中所起的作用。我们还比较了抑郁组与非抑郁组之间，以及述情障碍组与非述情障碍组之间音高引发的身体感觉的分布情况。此外，我们考察了它们与焦虑的关联。我们的研究结果表明，具有述情障碍特质和抑郁状态的个体对音高的身体感觉定位较差，同时伴有焦虑感和负面情绪的增强。这些结果表明，对声音的弥漫性身体感觉可能与焦虑感增强有关。因此，监测音高引发的身体感觉可能作为与抑郁症和述情障碍等疾病相关的情绪倾向的潜在指标。我们的研究揭示了身体对声音感觉的重要性，这一现象可能由内感受介导。这项研究增进了我们对声音、情绪和人体之间复杂关系的理解，为情绪障碍的潜在干预提供了见解。
