ODOUR SIMILARITIES AND THEIR MULTIDIMENSIONAL METRIC REPRESENTATION.

Odour qualitative similarities were collected on 18 Ss, using 10 diverse stimuli. Responses were in numerical category scale form, and were analyzed individually and pooled, by a nonmetric multidimensional scaling program TORSCA. It is suggested that the data are consistent with a degenerate metric space configuration here called a reflected simplex. Implications for psycho-physical odour quality typologies are noted.
