Temporal Data
Many sensory experiences have a temporal dimension, and several approaches have been proposed to capture changes in sensations with time. The workshop will review a few of those methods, including Time intensity, Temporal Attribute Discrimination, Progressive Profiling, Sequential Profiling, Temporal Dominance of Sensations, and Temporal Order of Sensations.

You know what you like, but what about everyone else? A case study on incomplete block segmentation of white-bread consumers
“One man’s meat is another man’s poison.” There will always be a wide range of consumer liking response across any product category. Cluster analysis can provide consumer segments based upon common liking that reflect underlying sensory preferences. To determine valid population segments requires a large sample of consumers. As the number of products tested by each consumer increases, experimental bias

Sweet and powerful: A two-attribute time intensity study of fruit liqueur / Doux et puissant: Une étude de deux attribut de temps l’intensité de la liqueur de fruits
Time intensity (TI) methods are used to measure perceived changes in the intensity of one, or sometimes two, sensory attributes over time in a product or stimuli. Evaluations are performed by a panel of well-trained human assessors.

A new method for analyzing time intensity curves based on the gamma distribution
Single-attribute time-intensity (TI) analysis is used to determine how a sensation changes with time for a given product or stimulus. Intensity data from a single TI panellist can be represented as a curve, which is roughly concave down but may be irregular or skewed. Depending on the system, a TI curve might display multiple peaks, but in some cases TI

Refinement of a statistical framework for an own-brand large-scale consumer quality program
Retailers benefit from understanding how consumers perceive the quality and value of their own-brand offerings, but a systematic approach is necessary with many products. A well designed consumer testing program provides efficiency and structure for ongoing quality monitoring, as well as guidance for product reformulation.

Distribution assumptions underlying consumer testing
To evaluate in-market products, routine sensory quality tests are conducted using verified consumers. Each product is matched to a competitor product with similar attributes, and presented to consumers by experimental design.

Shortlisting before ranking: perception of wine region quality by Ontario consumers
A choose-all-that-apply (CATA) question allows respondents to select multiple answers from a list. A technique called answer piping displays the respondent’s selections as possible responses in a subsequent question. Answer piping was used to allow consumers to shortlist wine-producing regions before ranking those regions for quality in a Chilean red wine consumer study conducted in fall 2007.
