Abstract:

Two contemporary problems related to the application of multidimensional scaling techniques are discussed and possible solutions presented. The first of these problems concerns the prohibitive number of judgments required in paired comparison tasks when the number of stimuli is large. Several procedures are proposed for reducing the necessary number of comparisons by using standard or reference stimuli. The second problem is that methods are needed for relating the psychological spaces obtained from scaling analyses to other behavioral data. One method, which involves embedding novel stimuli in previously defined psychological spaces, is described. Both problems are considered from a metric as well as nonmetric standpoint.
