Document Summary

Euclidian metric - the psychological distance metric between a pair of objects when the comparison is being made along integral perceptual dimensions. All the dimensions are included simultaneously in the distance calculation. City block metric - the psychological distance metric between a pair of objects when the comparison is being made along separable perceptual dimensions. Each dimension is included separately in the distance calculation. Domain general - a domain general construct is a psychological construct that operates the same way in different domains. Visual and auditory similarity, for example, may work in the same abstract way. Minimality assumption - an assumption of the geometric model that states that the nothing can be more similar to an object that it is to itself. Self-similarity is the maximum similarity and therefore the minimum distance. Multidimensional scaling (mds) - a computational technique that takes pairwise ratings of similarity and calculates the resulting psychological space of the entire set of objects.
