Sensory cues like music can influence our behaviour towards food. In the present study, the effect of music on hunger, fullness, desire to eat and liking of foods, while viewing real lunch food items, was investigated. To this end, emotions and physiological measures were obtained to understand the changes in hunger, fullness, desire to eat and liking. The study aimed to examine changes in hunger, fullness, desire to eat, and liking when viewing a lunch meal under silent and varying music conditions. Additionally, the study explored the potential role of emotions to explain these changes. A crossover experimental design was employed using 50 participants (17 males and 33 females) who observed lunch food items during a silent condition (control), or while listening to either liked or disliked music. The findings demonstrate the cross-modal influence of music on hunger and food liking ratings when viewing food. Hunger ratings were higher and more negative emotions were evoked while viewing lunch food items and listening to disliked music. In contrast, in the silent and liked music conditions, which elicited more positive emotions, there were increased ratings of healthy and unhealthy food pleasantness, overall food liking, and food satisfaction. Electrophysiological measures of heart rate (HR) and skin conductance (SC) were obtained while listening to music and viewing a lunch meal. Viewing food items while listening to disliked music evoked negative emotions and significantly increased SC compared to liked music or silent conditions. Viewing the food items under the silent condition evoked positive emotions and significantly increased HR compared to listening to liked and disliked music. This study showed that the participants' emotions, hunger level, liking, and electrophysiological responses when viewing food are influenced by music that varied with liking. Results from this study may assist in enhancing dining experiences, as well as influencing food choices and satisfaction with meals.
感官提示，如音乐，可以影响我们对食物的行为。在目前的研究中，研究了音乐对饥饿感、饱腹感、食欲和对食物的喜好的影响，同时观察了真实的午餐食物。为此，获得了情感和生理测量，以了解饥饿感、饱腹感、食欲和喜好的变化。本研究旨在考察在安静和不同音乐条件下观看午餐时饥饿感、饱腹感、食欲和喜好的变化。此外，该研究还探讨了情感解释这些变化的潜在作用。使用 50 名参与者（17 名男性和 33 名女性）进行了交叉实验设计，他们在安静条件（对照）或听喜欢或不喜欢的音乐时观察午餐食物。研究结果表明，音乐对观看食物时的饥饿感和食物喜好评分有跨模态影响。在观看午餐食物和听不喜欢的音乐时，饥饿感评分更高，情绪更消极。相比之下，在安静和喜欢的音乐条件下，情绪更积极，健康和不健康食物的愉悦感、整体食物喜好和食物满意度评分更高。在听音乐和观看午餐时获得了心率（HR）和皮肤电导（SC）的电生理测量。与喜欢的音乐或安静条件相比，观看食物时听不喜欢的音乐会引起负面情绪，并显著增加 SC。在安静条件下观看食物会引起积极的情绪，并显著增加 HR 与听喜欢和不喜欢的音乐相比。本研究表明，参与者在观看食物时的情绪、饥饿水平、喜好和电生理反应受到音乐的影响，音乐的变化与喜好有关。本研究的结果可能有助于提高用餐体验，以及影响食物选择和对餐食的满意度。
