Research into the influence of auditory cues upon food perception has increased in the past decade. Mechanisms evoked to explain crossmodal interactions between the auditory and gustatory senses include attentional, emotional, and affective mediators. In this study, the Temporal Dominance of Sensations (TDS) method was utilised to document the changes in taste and flavour of chocolate gelato while participants listened to music. After each TDS trial, the participants rated their emotions using intensity scales. Additionally, electrophysiological measures including heart rate, respiration rate, and skin conductance were obtained. As anticipated, listening to liked music evoked positive emotions (enjoyment, happiness, love, and satisfaction), while disliked music elicited negative emotions (disappointment, and disgust). No significant difference in terms of respiration parameters were observed while listening to music differing in liking. When compared to neutral and liked music, listening to disliked music exhibited the greatest change in skin conductance. Additionally, neutrally liked music significantly decreased blood volume pulse amplitude, while listening to liked music significantly increased heart rate. Partial Least Square Regression (PLSR) analysis was employed to explore associations between electrophysiological and sensory measures. Skin conductance and cardiovascular measures were both linked to the perception of gelato. Partial Least Square Path Modelling (PLS-PM) was also utilised to investigate the relationships between the electrophysiological measures, subjective ratings of emotion, and perception. The PLS-PM model showed that changes in cardiac and skin conductance measures were correlated with subjectively-rated emotions. Furthermore, these self-reported emotions evoked by music were significantly correlated with flavour.
在过去的十年中，人们对听觉提示对食物感知的影响的研究有所增加。用于解释听觉和味觉之间的跨模态相互作用的机制包括注意力、情绪和情感中介。在这项研究中，使用了感官时间主导（TDS）方法来记录巧克力冰淇淋的味道和风味在参与者听音乐时的变化。在每次 TDS 试验后，参与者使用强度量表对他们的情绪进行评分。此外，还获得了包括心率、呼吸率和皮肤电导在内的生理电测量值。正如预期的那样，听喜欢的音乐引起积极的情绪（享受、快乐、爱和满足），而听不喜欢的音乐则引起消极的情绪（失望和厌恶）。在听喜欢程度不同的音乐时，呼吸参数没有明显差异。与中性和喜欢的音乐相比，听不喜欢的音乐时皮肤电导的变化最大。此外，中性喜欢的音乐显著降低了血液体积脉搏幅度，而听喜欢的音乐则显著增加了心率。偏最小二乘回归（PLSR）分析用于探索生理电和感官测量之间的关联。皮肤电导和心血管测量都与冰淇淋的感知有关。偏最小二乘路径建模（PLS-PM）也用于研究生理电测量、主观情绪评分和感知之间的关系。PLS-PM 模型表明，心脏和皮肤电导测量值的变化与主观评定的情绪有关。此外，音乐引起的这些自我报告的情绪与风味显著相关。
