.— Previous work on content models of multidimensional similarity have mostly been concerned with the case of only qualitative variation. In this study a set of emotion words that varied both in content and intensity was used as stimuli. Subjects gave multidimensional ratio estimations, similarity estimations and also unidimensional ratings of intensity. Both individual data and group data were collected. Five different previously suggested content models of similarity failed to fit these data that showed large individual idiosyncratic variability. It is pointed out that previous work, where some of the models fitted rather well, was concerned with cases that were largely insensitive to deviations fram the models.
