Multidimensional perceptual scaling of musical timbres.

Two experiments were performed to evaluate the perceptual relationships between 16 music instrument tones. The stimuli were computer synthesized based upon an analysis of actual instrument tones, and they were perceptually equalized for loudness, pitch, and duration. Experiment 1 evaluated the tones with respect to perceptual similarities, and the results were treated with multidimensional scal...

A new proposal for metric in perceptual multidimensional scaling

We analyze a simplified probability model that assumes normality and homoscedasticity of vowel parameters’ distributions. We arrive at explicit formulae that describe functional relationship between a natural Euclidean distance function in the model and the confusability of vowel categories. We propose a solution to address a common case when confusability of a pair of vowel categories is very ...

Classifying Information Technologies: A Multidimensional Scaling Approach

A multidimensional scaling approach to mental multiplication.

Adults consistently make errors in solving simple multiplication problems. These errors have been explained with reference to the interference between similar problems. In this paper, we apply multidimensional scaling (MDS) to the domain of multiplication problems, to uncover their underlying similarity structure. A tree-sorting task was used to obtain perceived dissimilarity ratings. The deriv...
