The application of individual differences multidimensional scaling techniques to the study of interpersonal attraction
Bryson, R. B. (1977). The Application of Individual Differences Multidimensional Scaling Techniques to the Study of Interpersonal Attraction. Multivariate Experimental Clinical Research, 3(3), 123-131.
Individual differences multidimensional scaling procedures were used in two experiments to discern how judged similarity and perceptual similarity related to interpersonal attraction. In both experimental groups, subjects were also objects of judgment. The procedure permitted identifying judgment dimensions used by the group, and locating subjects on the dimensions in two ways: 1) in terms of how much each subject weighed each dimension in formulating judgments and 2) in terms of where each subject was judged to lie on each dimension. In the former case Euclidian distances between pairs of subjects across dimensions comprised a measure of perceptual similarity and in the latter case, a measure of judged similarity. In Experiment I, conducted on bridge players, best friend choices were significantly and independently related to both perceptual similarity and judged similarity. In Experiment II, conducted on a fundamentalist church group, degree of friendship across the range of perceptual and judged similarity was assessed. Results were consistent with those obtained in Experiment I.
