Possible issues“Videoconferencing in the Field: A Heuristic Processing Model” • This research uses dual-process cognitive theory to describehow people process information differently when it is deliveredvia videoconference rather than when it is delivered face-to-face.According to this theory, relative to face-to-face communication,people in videoconferences tend to be more influenced by heuristiccues—such as how likeable they perceive the speaker tobe—than by the quality of the arguments presented by thespeaker. This is due to the higher cognitive demands that videoconferencingplaces on participants. We report on a field study of medicalprofessionals in which we found differences in information processingas predicted: participants attending a seminar via videoconferencewere more influenced by the likeability of the speaker thanby the quality of the arguments presented, whereas the oppositepattern was true for participants attending in-person. We alsofound that differences in cognitive load explain these effects.The discussion on the theoretical model and associated findingsexplains why prior videoconference studies have not consistentlyfound main effects for media. The findings also show that videoconferencingis not like face-to-face communication, despite apparent similarities.
