Lunch melodies: Investigating the impact of music on emotions, hunger, liking, and psychophysiology while viewing a lunch meal
Sensory stimuli, such as music, can impact our eating behaviors. This study by Siangphloen et al. (2024) explored how music affects hunger, fullness, desire to eat, and food preferences while participants viewed real lunch food items. The research measured emotional responses and physiological changes to better understand how music influences these factors. The goal was to assess how hunger, fullness, desire to eat, and food preference shifted when participants viewed a meal in silence or with different types of music. The emotional role in these changes was also considered. The study used a crossover experimental design with 50 participants (17 males and 33 females) who were shown lunch food either in silence (control) or while listening to music they either liked or disliked. The results revealed a cross-modal effect of music on hunger and food preference ratings. When participants viewed food while listening to disliked music, hunger levels increased, and negative emotions were triggered. On the other hand, during silent and liked music conditions, which generated positive emotions, there were higher ratings for both healthy and unhealthy foods in terms of pleasantness, overall liking, and satisfaction. Electrophysiological data, such as heart rate (HR) and skin conductance (SC), were recorded while participants viewed the meal and listened to music. Negative emotions and higher SC were observed when viewing food while listening to disliked music, while the silent condition led to more positive emotions and increased HR compared to both liked and disliked music. The findings suggest that music, depending on preference, influences emotions, hunger, food liking, and physiological responses when viewing food. This research could help enhance dining experiences and influence food choices and satisfaction.
