INFORMATION DIVERSITY AND REPETITIVENESS INGSS SUPPORTED COGNITIVE CONFLICT TASK:AN EXPERIMENTAL INVESTIGATION

摘要

The issue of information dimension has not received enough attention in the group support systems (GSS)rnresearch. The major information dimensions are information diversity and information repetitiveness.rnInformation overload is a function of the information dimensions. Prior research demonstrates that increasingrninformation diversity and repetitiveness can have information overload effect on decision time in structuredrnand unstructured tasks. Group tasks, such as cognitive conflict tasks involve the use of diverse and repetitiverninformation cues. This paper discusses a research to examine the diversity and repetitiveness of informationrncues accessed by group decision makers engaged in cognitive conflict tasks. The study results demonstratedrnthe negative effect of information diversity and information repetitiveness on decision time. The researchrnfurther explores whether the use of a collective memory can influence the extent of diverse and repetitiverninformation cues accessed by the group decision makers.
