The Effects of Shared Cognition on Group Satisfaction and Performance: Politeness and Efficiency in Group Interaction.

This study investigates the effects of shared cognition on group member satisfaction and group task performance. The hypotheses are that groups who have shared cognition concerning communication rules, such as politeness and efficiency, will be more satisfied with their group processes and will perform a task better than will those in groups lacking shared cognition concerning communication rules. The research involved 67 groups (N = 236) performing a radio assembly task for 20 minutes. Group members in the shared cognition condition received the same instructions to communicate politely (or efficiently). In the non-shared cognition condition, some members in a group received instructions to communicate politely and other members in the same group received instructions to communicate efficiently. The data are consistent with the part of the hypothesis relating to satisfaction but not to the one relating to performance. [ABSTRACT FROM AUTHOR]
