Description

Previous Studies have argued that groups interacting via computers (CMC groups) have more equal participation among members than groups interacting face-to- face (FTF groups). The relation between participation equality and quality of decision making in FTF and CMC groups was examined using a hidden profile task (Stasser & Titus, 1985, 1987). University students read descriptions of 2 options of a decision making task, which contained identical information with other members or partial information biased against the most favorable option. Then they met in 3-person (or 5-person) FTF (or CMC) groups to discuss and decide the best option. In interacting face-to- face, 3-person groups have more participation equalization effects than 5-person groups. Whereas group size effects were eliminated in computer-mediated groups. Group members' decision, however, revealed that they were subject to biased information and failed to decide the most favorable option.
