A Partition of Group Performance into Informational and Social Components in a Hypothesis Generation Task.

Abstract

A technique is presented for partitioning group performance into two components: a component due to the increased information possessed by the group and a component representing the change in performance due to social interaction. The hypothesis-generation performance of individuals working alone was compared to the performance of interacting groups of four. The particular task employed permitted calculations of the veridical probabilities of generated sets of hypotheses. Analyses of results were based on a new method, obtained by pooling hypothesis sets from individual subjects to obtain 'synthetic' groups. This method permits direct comparisons of interacting and synthetic groups hypothesis generation performance. Using this method, we found that groups of four subjects were equivalent to synthetic groups of 1.8 subjects. (Author)
