Napping is a multivariate sensory method in which participants physically place stimuli on a large sheet of paper and orient them so that the distance between pairs represents a measure of dissimilarity. The two-dimensional nature of the task may be a limitation to the ability of this and similar methodologies to recover information about complex stimuli.(More)
Chemesthetic compounds, responsible for sensations such as burning, cooling, and astringency, are difficult stimuli to work with, especially when the evaluation task requires retasting. Here, we developed a protocol by which chemesthetic compounds can be assessed using sorting. We compared the performance of two cohorts of untrained assessors on this task,(More)

Stochastic multidimensional scaling models offer both theoretic and practical advantages over deterministic methods, which include confidence regions for parameter estimates (Carroll and Green, 1997), simultaneous estimation of the product dimensions and respondent segmentation (DeSarbo, Manrai and Manrai, 1994) and the estimation of distributions of(More)
