Ralph Waldo Emerson once cautioned that “a foolish consistency is the hobgoblin of little minds.” In this talk, this quote is playfully considered in light of consumer diversity as manifested in sensory evaluation studies.
TDS describes the evolution of the dominant sensory attributes during consumption. Dominance can be assessed as the sensation that captures the attention, the most striking, or the new sensation that pops up, but not necessarily the most intense. This wide definition implies that individual assessors within a panel might assess dominance differently, and even the same assessor could be using
Methods for Consumer Research, Volume One: New Approaches to Classic Methods brings together world leading experts in global consumer research who provide a fully comprehensive state-of-the-art coverage of advances in the classical methods of consumer science. The book touches on the latest developments in qualitative techniques, including coverage of both focus groups and social media, while also focusing on liking,
Despite the several differences in ingredients, processes and nutritional values, dairy foods as yogurts, fermented milks and milk beverages are widely accepted worldwide, and although they have their sensory profiling normally covered by descriptive analyses, the temporal perception involved during the consumption are rarely considered. In this sense, the present work aimed to assess the dynamic sensory profile of three
From a sensory perspective, sparkling wines are highly complex products. Carbonation imparts characteristic mouthfeel effects that include tingling and other sensations, and may trigger gustatory, olfactory, trigeminal, and auditory perceptions as well.
Conventional sensory methods often characterize products as if they are a static aggregation of attribute intensities. But it has long been recognized that many products have an important temporal component, and examples of this are seemingly limitless; consider that foods are chewed and broken down prior to swallowing with accompanying texture changes and flavour release, that carbonated beverages elicit numbing
Dominance rates arising from temporal dominance of sensations (TDS) data are almost always plotted and understood with reference to chance and significance lines. Chance lines are fully determined by the number of attributes, and represent what we might expect if poor reading but task-engaged monkeys picked the attributes. Significance lines are conventionally based on the 95% upper confidence limit for
To identify the sensory attributes that guide food choice, classical descriptive analyses are commonly used, however they do not take into account the dynamics involved during oral processing. The use of temporal methods provides more realistic information on the sensory changes during the time, approaching the consumers’ perception.
The present study was to determine if and how TCATA could discriminate two variants of the same snack (A, B) that had previously been demonstrated perceptually similar by consumer liking and diagnostics. Consumers evaluated five consecutive bites of each variant at McCormick & Co., Inc.: via temporal liking on Day 1, TCATA with 12 emotion attributes on Day 2, and
The feelings, tastes, flavors, and sounds elicited by ready-to-eat breakfast cereals in the mouth are perceived dynamically, and evolve within each bite, and over the multi-bite eating experience. Temporal check-all-that-apply (TCATA) is a temporal sensory method that extends the use of check-all-that-apply questions by allowing continuous selection of attributes based on applicability or noticeability. TCATA can permit characterization of the
