Group Size: Its Effects on Group Performance and on Individual Acquisition of Knowledge.
Jorgensen, Bruce W.
Subjects answered multiple-choice questions at three points in time. They worked alone, then in units of 1, 2, 3, 5, and 7 persons, and again alone. Performance on the task was to provide the following information: (1) initial ability level of subjects; (2) the ability of groups of differing size and leadership to utilize their resources; and, (3) the ability of individuals to acquire correct responses, as a function of their experience on the group task. Performance was predicted using Steiner's (1966, 1972) model of group productivity. Group performance on the task was a position function of group size for the sizes studied. Subsequent individual performance was difficult to interpret: Performance increased with group size for subjects who had been of size 5, and again increased for Ss who had worked in groups of 7. This duplicated the data of a pilot study. Patterns of process adaptation in groups of "critical" size are discussed as possibly responsible for this pattern. It was concluded that groups can facilitate the individual acquisition of knowledge. An application of this information, the small group examination, was discussed. (Author)
