Here we investigate associations between complex auditory and complex taste stimuli. A novel piece of music was composed and recorded in four different styles of musical articulation to reflect the four basic tastes groups (sweet, sour, salty, bitter). In Experiment 1, participants performed above chance at pairing the music clips with corresponding taste words. Experiment 2 uses multidimensional scaling to interpret how participants categorize these musical stimuli, and to show that auditory categories can be organized in a similar manner as taste categories. Experiment 3 introduces four different flavors of custom-made chocolate ganache and shows that participants can match music clips with the corresponding taste stimuli with above-chance accuracy. Experiment 4 demonstrates the partial role of pleasantness in crossmodal mappings between sound and taste. The present findings confirm that individuals are able to make crossmodal associations between complex auditory and gustatory stimuli, and that valence may mediate multisensory integration in the general population.
在此，我们研究复杂听觉刺激与复杂味觉刺激之间的关联。创作并录制了一首新颖的乐曲，采用四种不同的音乐表达方式来反映四种基本味觉类别（甜、酸、咸、苦）。在实验1中，参与者在将音乐片段与相应的味觉词汇配对时表现高于随机水平。实验2使用多维标度法来解释参与者如何对这些音乐刺激进行分类，并表明听觉类别可以与味觉类别以相似的方式组织起来。实验3引入了四种不同口味的定制巧克力甘纳许，并表明参与者能够以高于随机水平的准确率将音乐片段与相应的味觉刺激相匹配。实验4证明了愉悦感在声音与味觉之间的跨模态映射中的部分作用。目前的研究结果证实，个体能够在复杂的听觉和味觉刺激之间建立跨模态关联，并且效价可能在普通人群的多感官整合中起中介作用。
