Do panellists donkey vote in sensory Choose-All-That-Apply questions?

Sara King/ July 26, 2009/ Oral Presentation/ 0 comments

A so-called donkey voter selects candidates according to position on an election ballot. Are untrained sensory panellists similarly influenced by position when responding to choose-all-that-apply (CATA) questions? In sensory and consumer testing, lists of choices, conventionally presented in fixed order, allow panellists to indicate sensory perceptions without requirements for scaling. Results help in understanding products and drivers of hedonic response.

Segmentation of BIB consumer liking of high-fatigue products: Sensory confirmation of statistical methods

Consumer testing of products which create sensory fatigue have a number of serious challenges. The effect of consumption of alcoholic beverages, extremely spicy foods, intense flavors or numbing ingredients limit the collection of complete block data to a small number of samples. If a study with a large number of samples is conducted by collecting consumer data over several days,

Does purchase history increase the validity of consumer panels? A case study

Sara King/ July 26, 2009/ Poster/ 0 comments

In a random sampling of consumers, it is not unusual to have a proportion of the panellists who are neither users or purchasers of the product. This means that “liking” responses to products are not informed by either context or experience. This reduces the validity of the test. When we consider that choice reflects the ability to detect a difference,
