Social factors in the design and use of computer-mediated communication technology

摘要: Computer mediated communication technologies (CMC) encompass information technology, messaging systems (such as chat and instant messaging) desktop conferencing designed to facilitate group work. Prior research suggests CMC adoption fails when it interferes with subtle complex social dynamics of groups. Yet, empirical studies use that explicitly associate behavior design features are largely absent from the literature. Also conceptual tools for detecting describing such behavior. My addresses these absences by closely examining how supports interaction among geographically distributed work Qualitative findings indicate specific characteristics affords increased accountability stimulates or suppress different user Other both exchange (meeting scheduling) well (impression management) users. These extend media theory include communicative processes in which people satisfy informational needs. Quantitative demonstrate task performance is impaired users observed via application sharing video compared they not observed. sense presence others, can negatively impact on a cognitive-reasoning task. Implications demonstrate, paradoxically, where other researchers have found overall quality collaborative product may improve electronic conferencing, individual suffer. This dissertation also builds theoretical model relationship between interface context use. Drawing related perceptual psychology, affordances articulated used analyze reported here.
