Transitivity of preferences has been investigated for a long time in decision-making. In the field of perception, the pleasantness of odors raises several questions related to individual versus cultural or universal preferences and the existence of a classification in a delimited hedonic space. The aim of this study was to test transitivity in olfactory hedonicity using a first panel of 10 mixed odors and a second panel of 10 odors from a delimited floral category. Data were collected by paired comparisons in a two-alternative forced choice. Results in both panels showed a strong transitivity for each participant leading to a linear range of 10 odors classified by preference. However, ranges varied from one participant to another and the mean preferences of the group did not allow one to infer individual's hedonic classification of odors. Moreover, the individual classification appeared stable over time and undisturbed by odorant distractors. These findings suggest that humans have considerable ability to classify odors hedonically as a model of individual preferences in a sensory space usually considered to be more involved in affective/emotional states than in cognitive performances.
偏好的传递性在决策制定中已经研究了很长时间。在感知领域,气味的宜人程度引发了一些与个体与文化或普遍偏好以及在限定的愉悦空间中是否存在分类有关的问题。本研究的目的是使用第一组 10 种混合气味和第二组 10 种限定花香类别的气味来测试嗅觉愉悦感的传递性。通过在二选一的强制选择中进行成对比较来收集数据。两个面板中的结果均显示,每个参与者的传递性都很强,导致 10 种气味按偏好进行线性分类。然而,范围因参与者而异,并且组的平均偏好不允许推断个体对气味的愉悦分类。此外,个体分类在时间上表现稳定,不受气味干扰物的影响。这些发现表明,人类具有相当大的能力来对气味进行愉悦分类,这是一种在感官空间中个体偏好的模型,通常被认为更多地涉及情感/情绪状态,而不是认知表现。
