Multidimensional scaling techniques can be used to convert perceptions of dissimilarity to psychological maps, by treating dissimilarity ratings as ordinal scale distance estimates. In this study, listeners were asked to rate the dissimilarity of pairs of compressed versions of instrumental music phrases on two occasions separated by approximately one year, and the recovered psychological maps were compared to assess their stability over time. Results indicate that such maps derived from multidimensional scaling analyses are not necessarily more similar within a listener over time than between listeners.
