Presented at the 2015 Pangborn Symposium in Gothenburg, Sweden. Consumers vary in what they like and dislike. They may cluster into groups or segments of similar-minded individuals, but it is often difficult to determine what causes segments to exist. In a typical consumer product test, respondents are screened and profiled according to a series...

Poster: Establishing Consumer-Relevant Action Standards in Sensory Discrimination Testing

Presented at the 2013 Pangborn Symposium in Rio de Janeiro, Brazil.

Poster: The Effect of Dimensionality on Multivariate Mapping of Hedonic Data

Presented at the 2013 Pangborn Symposium in Rio de Janeiro, Brazil. Multivariate mapping techniques are valuable to sensory scientists because of their ability to visually represent differences among products in a multidimensional space and to connect these differences to hedonic assessments of the products. There are many mapping methods in use and their respective...
