[Contrast effects of background stimulus person on attitude similarity judgement and interpersonal attraction: a study of topic familiarity effect].
The purpose of this study was to examine the effects of a background stimulus person on attitude similarity judgement and interpersonal attraction. Mascaro and Graves (1973) argued that a contrast effect on perception of similarity mediated interpersonal attraction. In the present experiment, it was hypothesized that topic familiarity moderated the effects of a background stimulus person on attitude similarity judgement and interpersonal attraction. One hundred twenty-two (122) female students were randomly assigned to four groups, formed by two levels of topic familiarity and two levels of similarity for the background stimulus person. They saw the attitudes of two stimulus persons together, and were asked to rate perceived similarity and interpersonal attraction. Results showed that in familiar topic condition, contrast effect was not found for attitude similarity judgement, but it was found for interpersonal attraction. The finding suggested that presence of a background stimulus person immediately led to the contrast effect on interpersonal attraction.
