摘要
Previous research has shown that music can influence taste perception. While most studies to date have focused on taste intensity ratings, less is known about the influence of musical stimuli on other parameters of taste function. In this within-subjects experiment (N = 73), we tested the effects of three sound conditions (High Sweetness soundtrack – HS; Low Sweetness soundtrack – LS; and Silence – S) on sweet taste sensitivity, namely, detection and recognition. Each participant tasted nine samples of sucrose solutions (from 0 g/L to 20 g/L) under each of the three sound conditions in counterbalanced order. We assessed the lower concentrations at which participants were able to detect (detection threshold) and correctly identify (recognition threshold) a taste sensation. Additionally, the intensity and hedonic ratings of samples above the recognition threshold (7.20 g/L) were analyzed. Affective variations (valence and arousal) in response to the sound conditions were also assessed. Although music did not lead to significant differences in mean detection and recognition thresholds, a larger proportion of sweet taste recognitions was observed at a near-threshold level (2.59 g/L) in the HS condition. The intensity and hedonic ratings of supra-threshold conditions were unaffected by the music condition. Significant differences in self-reported mood in response to the sound conditions were also observed. The present study suggests that the influence of music on the sweet taste perception of basic solutions may depend on the parameter under consideration.

先前的研究表明，音乐会影响口味感知。尽管迄今为止的大多数研究都集中在口味强度等级上，但对音乐刺激对其他味觉功能参数的影响却少了。在这个受试者内的实验（n = 73）中，我们测试了三种声音条件（高甜度原声带 - HS；低甜味配乐 - LS；和silence - s）对甜味味道敏感性的影响，即检测和识别。每个参与者都以平衡的顺序在每个声音条件下的每个条件下都品尝了九种蔗糖溶液（从0 g/L到20 g/l）的样品。我们评估了参与者能够检测（检测阈值）并正确识别（识别阈值）的较低浓度。另外，分析了在识别阈值（7.20 g/L）上方的样品的强度和享乐评分。还评估了响应声音条件的情感变化（价和唤醒）。尽管音乐并没有导致平均检测和识别阈值的显着差异，但在HS条件下，在接近阈值的水平（2.59 g/l）上观察到了更大比例的甜味识别。上阈值条件的强度和享乐评级不受音乐状况的影响。还观察到自我报告的情绪在响应声音条件下的显着差异。本研究表明，音乐对基本溶液的甜味感知的影响可能取决于所考虑的参数。
