Abstract

A controlled laboratory study examined dyadic communication in face-to-face, telephone, and computer mediated text modes using high and low equivocal tasks. The dependent variables were decision time, consensus, change and communication satisfaction. The study failed to support media richness theory. While the findings support the hypothesis that decision time varies as a function of medium, they do not support similar hypotheses for consensus change and communication satisfaction. No support for hypothesized differences in decision time and consensus change as a function of the interaction of medium and task was found. However, there were consistent significant differences in all dependent measures based on task.
