New computer-based communications technologies make possible new or expanded forms of group work. Although earlier researchers suggest that scant social information in these technologies might cause status equalization in groups, no experimental test of this phenomenon has been made. In a laboratory experiment, we compared face-to-face communication with(More)
The paper suggests a structured task analysis and design technique which is based on the "levels-stages" model of a user action. The analysis of existing user tasks employs a top-down strategy. The first stage, dictated by the action model, decomposes the tasks into functional subtasks. The second stage decomposes the subtasks into functionally primitive(More)
During the past several years, a number of investigators have hypothesized that electronic mail and other computer-mediated communication technologies greatly attenuate social context cues (Hiltz and Turoff, 1978; Short, Williams, and Christie, 1976; Kiesler, Siegel, and McGuire, 1984). Equalization across status categories has been observed in studies of(More)
An experiment was performed to test a “distinct-window” conferencing screen design as an electronic cue of social status differences in computer-mediated group decision-making. The screen design included one “distinct” window to symbolize high-status, and two “nondistinct” windows to symbolize low-status. The results indicated that the distinct-window(More)
