一般来说，喜好是整体衡量的，但可能会随着食物摄入量的变化而变化，比如感官知觉。用通常的顺序喜好量表的类别替换感觉的时间主导（TDS）中的属性使得可以在食用产品时监控喜好的变化（Sudre 等人，2012）。这种方法可以更好地理解感觉的时间主导对喜好的影响以及在产品摄入期间喜好的演变。因此，可以将享乐时间数据和描述性时间数据（TDS 配置文件）关联起来，这将识别喜好的驱动因素，即当被引用为主导时会导致喜好减少或增加的属性。六十八位法国消费者参加了四场实验室会议。在第一节课中，受试者必须品尝六种口味的新鲜奶酪，并表明他们对每种产品的总体喜好。在第二次品尝的整个过程中评估了对相同产品的暂时喜好。第三阶段是对相同产品的 TDS 的测量，并且只记录了优势（没有记录强度）。最后，在第四次会议中，在开始品尝每个样品后1分钟记录对相同产品的喜爱程度。喜欢的测量表明，暂时的喜欢比经典的喜欢更具辨别力，并且经典的喜欢分数可能是在吞咽之前给出的。然而，在询问喜欢分数之前等待 1 分钟会减少对产品的歧视。此外，结合从同一消费者获得的时间喜好和 TDS 数据，可以建议产品的属性以及对这些属性的感知导致喜欢或不喜欢产品的时间。这是“喜欢的积极或消极时间驱动因素”（TDL）的新概念。该论文提出在给定属性被认为是主导属性 (LWD) 时计算个人平均喜好分数，并对主题的这些 LWD 值进行平均，以提取特定产品或一组产品的 TDL。 (C) 2014 Elsevier Ltd. 保留所有权利。
Generally liking is measured overall but is likely to vary over the food intake, like sensory perception. Replacing the attributes in Temporal Dominance of Sensations (TDS) by the categories of a usual ordinal liking scale makes it possible to monitor liking changes while eating a product (Sudre et al., 2012). This methodology allows for a better understanding of the influence of temporal dominance of sensations on liking and liking evolution over the time of product intake. Thus, it is possible to associate hedonic temporal data and descriptive temporal data (TDS profiles), which would identify drivers of liking, that is attributes which, when cited as dominant, would lead to a decrease or an increase of liking. Sixty-eight French consumers participated in four lab sessions. During the 1st session, the subjects had to taste six flavored fresh cheeses and to indicate their overall liking for each product. Temporal liking of the same products was evaluated throughout the tasting in the 2nd session. The 3rd session was a measure of TDS for the same products and only dominance was recorded (no intensity recorded). Finally, in the 4th session, the measure of liking of the same products was recorded 1 min after the beginning of tasting of each sample. Measures of liking showed that temporal liking is more discriminative than classic liking, and that classic liking scores may have been given before swallowing. However, waiting for 1 min before asking a liking score decreases discrimination of the products. Furthermore, combining temporal liking and TDS data obtained from the same consumers allowed to suggest the attributes and the times to which the perception of those attributes is responsible for the liking or disliking of the product. This is a new concept of "positive or negative Temporal Drivers of Liking" (TDL). The paper proposes to compute individual average liking scores while a given attribute was perceived as dominant (LWD) and to average those LWD values over the subject for extracting the TDLs of a specific product or of a group of products.
