Emotional and electrophysiological measures correlate to flavour perception in the presence of music

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 subjectivel...
