Female subjects were asked to evaluate either an attractive or unattractive male stimulus person under one of the three experimental conditions; while listening to avant-garde, rock music, or no music at all. Responding on the Interpersonal Judgement Scale (IJS: Byrne, 1971) and a seven-point physical attractiveness scale, subjects indicated more positive evaluations of and attraction toward attractive than unattractive stimulus person. In addition, subjects responded with more positive evaluations of, greater attraction toward, and more positive assessments of physical attractiveness under the rock music than under the avant-garde music condition. These results are discussed in terms of the Byrne-Clore reinforcement-affect model of interpersonal attraction with implications for future research. (Author)
