It has been hypothesized that social influence processes are altered in computer-mediated-communication (CMC) due to the lack on non-verbal information available across a computer. In these three studies, confidence ratings were used in an attempt to replace some of the non-verbal cues lost in CMC. Subjects participated in group decision making tasks in which the distribution of preferences and confidences were simulated. The results of these three experiments suggest that confidence ratings do not have an effect on an individual's preference decision but may be used to assess one's probability of persuading the other members of the group. The confidence ratings did not increase the probability of a group reaching a consensus decision. In addition, the results suggest that communication patterns in CMC are altered and, together with the lack of non-verbal cues, may result in changes in the social influence process.
