A model of conversational distance violations that claims that these violations mediate communication outcomes such as source credibility, source attraction, and learning was examined in a study involving 136 undergraduate students. The students were tested in small group settings using eight confederates, four rated highly and four lowly in attraction and in credibility as measured in the dimensions of competence, composure, character, extroversion, and sociability. Contrary to the findings in all previous research that tested the model, a consistent main effect for reward was not found. There was a trend toward attraction, especially social attraction, being higher in the rewarding than the nonrewarding condition; however, similar results did not occur for persuasion and credibility.
