Frisson is characterised by tingling and tickling sensations with positive or negative feelings. However, it is still unknown what factors affect the intensity of frisson. We conducted experiments on the stimulus characteristics and individual's mood states and personality traits. Participants filled out self-reported questionnaires, including the Profile of Mood States, Beck Depression Inventory, and Big Five Inventory. They continuously indicated the subjective intensity of frisson throughout a 17-min experiment while listening to binaural brushing and tapping sounds through headphones. In the interviews after the experiments, participants reported that tingling and tickling sensations mainly originated on their ears, neck, shoulders, and back. Cross-correlation results showed that the intensity of frisson was closely linked to the acoustic features of auditory stimuli, including their amplitude, spectral centroid, and spectral bandwidth. This suggests that proximal sounds with dark and compact timbre trigger frisson. The peak of correlation between frisson and the acoustic feature was observed 2 s after the acoustic feature changed, suggesting that bottom-up auditory inputs modulate skin-related modalities. We also found that participants with anxiety were sensitive to frisson. Our results provide important clues to understanding the mechanisms of auditory-somatosensory interactions.
颤栗的特征是伴随着积极或消极情绪的刺痛和瘙痒感。然而，目前尚不清楚是什么因素影响颤栗的强度。我们进行了关于刺激特征和个体情绪状态和人格特质的实验。参与者填写了自我报告的问卷，包括心境状态问卷、贝克抑郁量表和大五人格量表。他们在 17 分钟的实验过程中持续通过耳机聆听双耳刷擦和敲击声音，并对颤栗的主观强度进行指示。在实验后的访谈中，参与者报告说刺痛和瘙痒感主要来自他们的耳朵、颈部、肩膀和背部。互相关结果表明，颤栗的强度与听觉刺激的声学特征密切相关，包括它们的幅度、频谱质心和频谱带宽。这表明具有暗调和紧凑音色的近端声音会引发颤栗。在声学特征改变后 2 秒观察到颤栗与声学特征之间的相关峰值，表明自下而上的听觉输入调节与皮肤相关的模态。我们还发现，焦虑的参与者对颤栗很敏感。我们的研究结果为理解听觉-躯体感觉相互作用的机制提供了重要线索。
