Effects of telecommunication media upon information sharing andteam performance: some theoretical and empirical observations

Theoretical concepts related to decision-making, group dynamics, and communication processes are reviewed. A psychological distancing model of electronic media is described. Issues related to the role of electronic media in networking decision-makers are highlighted. Several laboratory studies that show some of the effects video, audio, and computer teleconferencing can have upon group interaction patterns and productivity are described. It is found that increasing communication richness does not guarantee improved group performance. Task demands as well as individual difference factors can affect the way groups use available media. It is concluded that existing theory is not yet sophisticated enough to account for all of the results observed. A more comprehensive theory of communication processes is needed that specifically addresses group-to-group interaction processes
