Abstract Research on taste-shape correspondences has focused on one-to-one taste/shape matching tasks. However, foods and drinks tend to involve multiple shapes (or shape attributes) and tastes that co-occur at different moments of our eating experiences. In the present research, we assessed whether food concepts involving more than one taste (e.g., “sweet and sour”) would be associated with pairs of round and/or angular shapes. The participants matched pairs comprising angular and round shapes with “sweet and sour” food concepts more often than with other single taste and taste combination concepts, in a manner that is broadly consistent with studies involving one-to-one taste/shape matches. These results were observed both when the participants were presented with the shape pairs alone (Experiment 1) or along with a product’s packaging (Experiment 2). We conclude by presenting possible explanations for the results obtained, as well as directions for future research.

与“酸甜”食物概念相关的形状

摘要 口味-形状对应的研究集中在一对一的口味/形状匹配任务上。然而，食物和饮料往往涉及多种形状（或形状属性）和味道，它们在我们饮食体验的不同时刻共同出现。在本研究中，我们评估了涉及多种口味（例如，“酸甜”）的食物概念是否与成对的圆形和/或角形形状相关。与其他单一口味和口味组合概念相比，参与者以与涉及一对一口味/形状匹配的研究大体一致的方式，将包括角形和圆形的食物对与“酸甜”食物概念相匹配。当参与者单独看到形状对（实验 1）或连同产品的包装（实验 2）时，都会观察到这些结果。我们最后提出了对所得结果的可能解释，以及未来研究的方向。
