Benefits and limitations with using Temporal Check-All-That-Apply (TCATA) with consumers to evaluate perceptually similar variants of a snack product

Sara King/ August 20, 2017/ Poster/ 0 comments

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

Do teenaged chocolate-flavored cereal consumers go cuckoo trying to do TCATA while eating Cocoa Puffs?

Sara King/ August 20, 2017/ Oral Presentation, Poster/ 0 comments

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

Perception of carbonation in sparkling wines using descriptive analysis (DA) and temporal check-all-that-apply (TCATA)

Sara King/ July 23, 2017/ Peer-reviewed Paper/ 0 comments

Several methods exist in order to profile complex matrices that change over time. In this study, two descriptive methodologies, descriptive analysis (DA) and temporal check-all-that-apply (TCATA) were used to analyze the complex perceptions associated with carbonation and compare the profiles from each method.

Comparison of static and dynamic sensory product characterizations based on check-all-that-apply questions with consumers

Sara King/ July 22, 2017/ Peer-reviewed Paper/ 0 comments

The aim of the present work was to compare static and dynamic sensory product characterizations based on check-all-that-apply (CATA) questions with consumers. Three studies involving a total of 310 consumers were carried out. In each study, a between-subjects experimental design was used to compare static sensory characterizations obtained using CATA questions with dynamic characterizations over a relatively short time period

Analysis of TCATA Fading data: Imputation of gaps in temporal profiles

Sara King/ July 22, 2017/ Peer-reviewed Paper/ 0 comments

Temporal Check-All-That-Apply (TCATA) Fading is a variant of TCATA where selected terms gradually and automatically become unselected over a predefined period of time and assessors are asked to re-select the terms if they still apply. Gaps in the temporal profile for a TCATA term may arise if assessors do not immediately re-select a fully faded term, making it difficult to

Characterizing dynamic sensory properties of nonnutritive sweeteners with temporal check-all-that-apply (TCATA)

Sara King/ June 20, 2017/ Peer-reviewed Paper/ 0 comments

Temporal check-all-that-apply (TCATA) is a rapid method where attributes are actively checked and unchecked to track sensations over time, so that the checked words fully describe the sample in any given moment. Here, we characterize the temporal profiles of sweeteners using TCATA. In two experiments, sweeteners were tested in water at concentrations known to elicit weak to moderate sweetness.

Identification of drivers of (dis)liking based on dynamic sensory profiles: Comparison of Temporal Dominance of Sensations and Temporal Check-All-That-Apply

Mpfindlay_9j5a2s5k/ February 1, 2017/ Peer-reviewed Paper/ 0 comments

Temporal Dominance of Sensations (TDS) and Temporal Check-All-That-Apply (TCATA) are two multi-attribute methods for dynamic sensory characterization. Previous research has shown that both methodologies provide complementary information. However, it remains an open question which of the two approaches better explains consumers’ hedonic perception of products. In this context, the aim of the present work was to compare TDS and TCATA

Does a familiarization step influence results from a TCATA task?

Sara King/ January 23, 2017/ Peer-reviewed Paper/ 0 comments

Temporal Check-All-That-Apply (TCATA) is a multi-attribute temporal approach that extends CATA questions. It is based on continuous selection of the sensory attributes that are perceived as applicable for describing a focal sample during consumption. Compared to CATA, TCATA is a relatively intense and demanding task for consumers who have to focus their attention on the evolution of the sensory characteristics

Comparison of two TCATA variants for dynamic sensory characterization of food products

Sara King/ December 23, 2016/ Peer-reviewed Paper/ 0 comments

Temporal Check-All-That-Apply (TCATA) has been recently introduced as a method for temporal sensory product characterization. This method requires assessors to select all the terms they consider applicable at each moment of the evaluation, and to de-select terms when they are no longer applicable. In the present work a variant of TCATA, TCATA Fading, is presented and compared to TCATA.

Perception dynamics of grain-based ready-to-eat cereal products using TCATA

Mpfindlay_9j5a2s5k/ October 31, 2016/ Oral Presentation/ 0 comments

The breakdown of grain-based ready-to-eat cereals in the mouth occurs relatively quickly, but it is at this stage when the consumer experiences directly the sensory properties of the cereal. The feelings, tastes, flavors, and sounds elicited in mouth are not static. Rather, these sensations are perceived dynamically, and evolve within each bite, and over the multi-bite eating experience. Temporal check-all-that-apply
