Abstract
Kruskal's non-metric multidimensional scaling technique was applied to interstimulus distances obtained from a complete paired comparison experiment where Ss rated the difference between 3-component taste mixtures. Results are compared with those obtained using a cross-modal method in which Ss matched taste mixtures to pictorial representations of such mixtures. Both cross-modal and paired comparisons data are well fitted in 3-dimensional non-Euclidean spaces. In both experiments the sets of co-ordinates from the scalings resemble the chemical composition of the taste mixtures used, and the two scalings are very similar to each other.
