Reports 2 studies, using a total of 304 university students, in which a likable or unlikable communicator delivered a persuasive message via writing, audiotape, or videotape. In both studies the likable communicator was more persuasive in video- and audiotape than in writing, but the unlikable communicator was more persuasive in writing. Thus, communicator likability was a significant determinant of persuasion only in the broadcast modalities. Other findings suggest that Ss process more communicator cues when exposed to video- and audiotape messages than when exposed to written ones and that communicator-based (rather than message-based) cognitions predicted opinion change primarily in video and audiotape conditions rather than in written ones. It is concluded that video- and audiotapes enhance communicator-related information, so that communicator characteristics exert a disproportionate effect on persuasion when messages are broadcast. Findings are also discussed in relation to "vividness" phenomena. (40 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
