title: BRIEF REPORT: ADDITIONAL DATA ON DISTORTION DUE TO AGGREGATION IN NONMETRIC MULTIDIMENSIONAL SCALING.
abstract: A previous research report investigated the effect of aggregation on nonmetric multidimensional scaling solutions in which the scaled stimuli were adjectives. Aggregate solution configurations were found to resemble substantially the configurations based on individual similarity data. However, recent replications on nonadjectival stimuli indicate substantial distortion due to aggregation. Preliminary conjectures are made about the adjective- object differences. The importance of the issue for multidimensional scaling is underscored by citing recent developments in scaling techniques.
