ABSTRACT
This study reports an experiment that examines the effects that face-to-face meetings (FF) and two modes of videoconferencing, switching video (SV), which shows only the current speaker, and mixing video (MV), which shows each group member simultaneously, have on turn distribution and the quality of small group decision making. The subjects were 200 undergraduate students and the task was the NASA Moon Survival Problem. Multiple comparison tests indicated that MV yielded significantly higher group decision quality than FF. The other pairs, FF-SV and SV-MV, showed no significant differences. With regard to turn taking, there was almost no difference between SV-MV.
