The post-pandemic context has changed the modes for collecting data in sensory and consumer science. The objectives of this research were to analyze consumers' associations of food consistency and to study two virtual modes of the Free Word Association test (FWA). This test was administered to 209 consumers (180 women, 29 men, 18-45 years old) asynchronously (i.e. self-administered) and synchronously (i.e. face to face interviews). The Cognitive Salience Index (CSI) was calculated, and the structure of the social representation was analyzed. Correspondence analysis showed that food consistency was a mixture of concepts related to structure, hardness and several aspects of auditory (e.g., Crunchy, Crispy), tactile (e.g. Smooth, Spreadable) and oral texture (e.g., Creamy, Gummy). Slightly consistent food was associated with something soft, liquid or semisolid, and very consistent food to something hard and resistant. Consistent food was more related to "very" than to "slightly consistent." The CSI depended on the stimulus presented (p < 0.05). Regarding the social representation structure, the central core had the highest CSI for all stimuli (CSI ≥ 0.13, p < 0.05). Consumers defined "very consistent, consistent and slightly consistent food" by naming more foods in the synchronous mode than in the asynchronous one. In the asynchronous mode, consumers took more time to complete the test. The virtual FWA test (asynchronous or synchronous) showed some differences in the associations of term consistency, due to the lack of spontaneity in the first minute. It is important to adjust the methodologies to standardize the times in both modes.
大流行后的背景改变了感官和消费者科学中数据收集的模式。本研究的目的是分析消费者对食物稠度的联想,并研究自由联想测试(FWA)的两种虚拟模式。该测试以异步(即自我管理)和同步(即面对面访谈)的方式对 209 名消费者(180 名女性,29 名男性,18-45 岁)进行了测试。计算了认知显著性指数(CSI),并分析了社会代表结构。对应分析表明,食物稠度是与结构、硬度和听觉(例如嘎吱嘎吱,脆)、触觉(例如光滑,可涂抹)和口腔质地(例如奶油状,粘稠)相关概念的混合。稍稠的食物与柔软、液体或半固体有关,非常稠的食物与坚硬和有抵抗力的食物有关。稠度一致的食物与“非常”比“稍”更相关。CSI 取决于呈现的刺激(p<0.05)。关于社会代表结构,中央核心对所有刺激的 CSI 最高(CSI≥0.13,p<0.05)。消费者通过在同步模式下比在异步模式下命名更多的食物来定义“非常稠、稠和稍稠的食物”。在异步模式下,消费者需要更多的时间来完成测试。虚拟 FWA 测试(异步或同步)由于缺乏第一分钟的自发性,在术语一致性的联想上显示出一些差异。重要的是要调整方法,以规范两种模式的时间。
