Abstract:

This study investigated the effects of individual experience versus mixed individual and group experience on individual and group performance in rule induction. Random series of eight rule-induction tasks were performed by sets of three participants randomly assigned to either individual training (performing all tasks in a nominal group) or to mixed training (alternating nominal and collaborative group task performance). Subsequent individual and group performance were measured. A general positive group-to-individual transfer was shown. In the individual posttest, mixed-training participants performed error checking more promptly and as a result generated fewer nonplausible final solutions than did individual-training participants. In the group posttest, mixed-training groups were superior in collective error checking and more effective in collective truth detection than were individual-training groups. Discussion focuses on how group experience in rule induction influences group member learning and subsequent group performance. Copyright 2000 Academic Press.
