Eating disorder tendencies are psychological characteristics that are prevalent in healthy young females and are known to be among the risk factors for eating disorders such as anorexia and bulimia nervosa. People with greater eating disorder tendencies strongly associate sweet and fatty foods with weight gain and strictly avoid consuming such foods. However, little is known about how eating disorder tendencies influence the association between taste and body shape impression. Research on crossmodal correspondences suggests that people preferentially associate sweet tastes with round shapes, and individual differences affect the degree of such associations. This study investigates how the degree of taste-shape matching is related to eating disorder tendencies with a preliminary investigation of what mediates this relationship. Two experiments were conducted: in Experiment 1, healthy participants rated the degree of association between basic taste words (sweet/sour/salty/bitter) and roundness of shape and subsequently completed questionnaires addressing eating disorder tendencies. In Experiment 2, participants answered additional questionnaires addressing obsessiveness, dichotomous thinking, and self-esteem. The results of Experiment 1 indicated a positive correlation between drive for thinness, which is one indicator of an eating disorder tendency, and the degree of matching sweetness to round shape. Experiment 2 replicated the results of Experiment 1 and revealed the mediating effect of obsessiveness. These findings suggest a relationship between individual differences in taste-shape matching and eating disorder tendency and the preliminary mediating role of obsessiveness. The present study provides new insight into the role of sweet-round matching in eating disorder tendencies and the associated psychological mechanisms.

评估追求稀薄度和口味-形状对应关系之间的关系。

饮食失调倾向是健康年轻女性普遍存在的心理特征，已知是厌食症和神经性贪食症等饮食失调症的危险因素之一。饮食失调倾向较重的人将甜食和高脂肪食物与体重增加密切相关，并严格避免食用此类食物。然而，人们对饮食失调倾向如何影响味觉和体型印象之间的关联知之甚少。对跨模态对应的研究表明，人们优先将甜味与圆形联系起来，而个体差异会影响这种联系的程度。本研究调查了味形匹配程度如何与饮食失调倾向相关，并初步调查了介导这种关系的因素。进行了两个实验：在实验 1 中，健康参与者对基本味觉词（甜/酸/咸/苦）与形状的圆度之间的关联程度进行评分，随后完成了针对饮食失调倾向的问卷调查。在实验 2 中，参与者回答了额外的问卷，这些问卷涉及强迫症、二分法思维和自尊。实验 1 的结果表明，食欲不振（饮食失调倾向的一个指标）与甜味与圆形的匹配程度之间呈正相关。实验二复制了实验一的结果，揭示了强迫症的中介作用。这些发现表明味型匹配的个体差异和饮食失调倾向之间存在联系，以及强迫症的初步中介作用。本研究为甜圆匹配在饮食失调倾向和相关心理机制中的作用提供了新的见解。
