This study aimed to assess consumers' implicit and explicit recall, understanding and perceptions of products with a nutrition claim and a symbol depicting 'health,' and to determine whether these perceptions differed among Nutrition Facts table (NFt) users vs. nonusers. In an online survey, participants (n = 1997) were randomized to one of eight conditions in a 2 × 2 × 2 factorial design, consisting of a label with a claim (present/absent) a heart-shaped symbol depicting 'health' (present/absent) for a healthier or less healthy soup. Participants were shown a label for 10 s and asked whether they recalled seeing a claim. If participants answered yes, they were then asked to describe their response using open-ended questions. Participants also rated the product's perceived nutritional quality and purchase intentions using seven-point Likert scales. In the claim condition, most participants (75%) were able to recall the presence of a claim, while 12% incorrectly mentioned the presence of a claim when there was none. Claims likely attracted consumers' attention and increased perceived nutritional quality, although with limited influence among NFt users (23%). The symbol depicting 'health' did not enhance perceived nutritional quality or purchase intentions. Although most participants (77%) made their decisions implicitly using the front of labels, those who used the NFt had a better understanding of the nutritional quality of products.
本研究旨在评估消费者对带有营养声称和描绘“健康”的心形符号的产品的内隐和外显回忆、理解和看法,并确定这些看法是否在营养事实表(NFt)使用者和非使用者之间存在差异。在一项在线调查中,参与者(n=1997)被随机分配到 2×2×2 析因设计的八种条件之一,该设计由具有声称(存在/不存在)的标签和描绘“健康”的心形符号(存在/不存在)组成,用于更健康或不太健康的汤。参与者观看标签 10 秒钟,并被问及是否记得看到过声称。如果参与者回答是,他们随后被要求使用开放式问题描述他们的反应。参与者还使用七点李克特量表评估产品的感知营养质量和购买意向。在声称条件下,大多数参与者(75%)能够回忆起声称的存在,而 12%的参与者在没有声称的情况下错误地提到了声称的存在。声称可能引起了消费者的注意,并提高了感知的营养质量,尽管对 NFt 用户的影响有限(23%)。描绘“健康”的心形符号并没有增强感知的营养质量或购买意向。尽管大多数参与者(77%)使用标签的正面进行了内隐决策,但使用 NFt 的参与者对产品的营养质量有更好的理解。
