The aim of the present work was to assess the influence of nutrition information format on attentional capture and consumers' understanding. Sixteen labels of two products (yoghurt and pan bread) were designed following a four 2-level factors full factorial design with the following variables: label background design, type of product, nutrition information format and traffic light system. The labels were presented to 178 consumers, who were asked to decide whether the fat/sodium content of each yoghurt/pan bread label was medium or low. Participant responses and reaction times were recorded. Results showed that type of product, nutrition information format and traffic light system significantly affected the time needed by consumers to find the nutrition information and to classify the labels according to their content of a given nutrient. Meanwhile, consumers' understanding of the labels was mostly affected by the content of the nutrient and the presence of the traffic light system.
本研究旨在评估营养信息格式对注意力捕获和消费者理解的影响。采用四因素 2 水平完全因子设计，设计了两种产品（酸奶和面包）的 16 个标签，分别为标签背景设计、产品类型、营养信息格式和信号灯系统。将标签呈现给 178 名消费者，要求他们判断每个酸奶/面包标签的脂肪/钠含量是中等还是低。记录参与者的反应时间和反应。结果表明，产品类型、营养信息格式和信号灯系统显著影响消费者找到营养信息和根据特定营养素的含量对标签进行分类所需的时间。同时，消费者对标签的理解主要受到营养素含量和信号灯系统的影响。
