THE COMMUNICATIVE PROCESS OF GROUP WORKS USING INTERNET
Nakayama, M.S., Osaka City University, Japan
We studied how group works are carried out using Internet to make a decision or to solve a problem. We used Internet TV conference system and bulletin board, compared with Face-to-Face (FTF) group process. In computer-mediated communication (CMC), some information is filtered. The types of filtered information depend upon the kind of CMC. For example, in text-based CMC that has been studied a lot previously, multimedia information such as voices and face expressions is filtered. It was discussed that the filtering of the information during group works would cause the communicative equality and reduction of interpersonal pressure in text-based CMC. On the other hand, Internet TV telephone or Internet TV conference system has been popularized recently, and CMC with multimedia information was realized. In this study, we examined the characteristics of group process in CMC with multimedia. In the experiment, the subjects interacted in pairs. The dyads participated in one of three conditions; TV conference, bulletin board, and FTF condition. Two kinds of tasks were employed. One was decision making for dilemma problem and the other was logical problem solving. The dyads were required to make one solution through discussion. The participations to the discussion (the number of utterance), the characteristic of decision making (risk-prone or risk- averse), the characteristics of communicative process, and personal awareness were analyzed. The results showed the influences of filtered information in CMC.
