Signal Detection Analysis of Computer Enhanced Group Decision Making Strategies

摘要

Three experiments were performed to test Sorkin's (2001) signal detection model of group decision making. The first two experiments compared various sequencing protocols which determine the order in which group members speak during group deliberation. The third experiment also compared these sequencing protocols but used correlated information sources so that some group members shared some information sources. It was predicted that the System for Optimally Rapid Collaboration (SORC) sequencing rule would produce the most rapid and accurate group decisions. While the results are mixed, there is some evidence that the SORC method is more accurate and in some situations more rapid than a random sequencing protocol.
