Abstract Sensory scientists have adapted several sensory methods to fit children’s cognitive abilities according to their different developmental stages. Although children have been reported to be able to use sensory methods to describe foods and beverages, published applications are limited to static characterizations. In this context, the objective of the study was to evaluate the feasibility of using two dynamic methods (temporal check-all-that-apply -TCATA- and Temporal dominance of sensations -TDS-) for sensory characterization with children. A video featuring colored circles (varying in size, appearing and disappearing) was used to convey the idea of temporal perception and to familiarize children with the methods. A series of six vanilla milk desserts was used in the tasting session. A total of 102 children (8 to 12 years old) recruited from two Uruguayan schools participated in the study. They were randomly divided in two groups, each of which used one of the methods. Results showed that TCATA and TDS allowed capturing the dynamics in the video. However, TCATA provided a more detailed description of how the colored circles evolved with time than TDS. In the case of the milk desserts samples, both methodologies showed similar results regarding the most relevant sensory characteristics. However, children mostly used them as static methods. In the TDS task, children dithered for long before selecting a new attribute, which points towards difficulties in evaluating dominance. Results from the present work suggest that refinements are needed to make TCATA and TDS methods applicable with children for characterizing food stimuli.

儿童能否使用时间感官方法来描述视觉刺激和食物刺激？

摘要 感官科学家根据儿童不同的发展阶段，采用了多种感官方法来适应儿童的认知能力。尽管据报道儿童能够使用感官方法来描述食物和饮料，但已发布的应用程序仅限于静态表征。在这种情况下，该研究的目的是评估使用两种动态方法（时间检查所有应用 -TCATA-和感觉的时间优势 -TDS-）对儿童进行感官表征的可行性。一个以彩色圆圈（大小不一、出现和消失）为特色的视频被用来传达时间感知的概念并让孩子们熟悉这些方法。品酒会上使用了一系列六种香草牛奶甜点。从乌拉圭两所学校招募的总共 102 名儿童（8 至 12 岁）参加了这项研究。他们被随机分为两组，每组使用其中一种方法。结果表明，TCATA 和 TDS 允许捕捉视频中的动态。然而，TCATA 提供了比 TDS 更详细的彩色圆圈如何随时间演变的描述。在牛奶甜点样品的情况下，两种方法在最相关的感官特征方面都显示出相似的结果。然而，孩子们大多将它们用作静态方法。在 TDS 任务中，孩子们在选择新属性之前犹豫了很长时间，这表明在评估优势方面存在困难。当前工作的结果表明，需要进行改进以使 TCATA 和 TDS 方法适用于儿童来表征食物刺激。
