团体决策支持系统和团体讨论对团体决策的影响

A small group decision making task was used to explore the role of Group Decision Support System ( GDSS) and group discussion during the process of group judgement. Ss were 60 students from Forestry University of Beijing and Agriculture University of Beijing. The accuracy of group judgment and the consistency among group members were recorded under four experimental conditions formed by GDSS and group discussion. ANOVA was employed to analyze the data under the two factors. The results indicated that GDSS enhanced the accuracy of group judgment significantly. The results also showed that group discussion helped group members to make an accurate and consistent judgement.
