Group Communication During Resource Dilemmas: 4: The Effect of Group Size

Previous theory and research implies that increasing the size of groups facing resource dilemmas results in poorer outcomes, but no previous study has allowed for communication among group members. The present study relates group size with communication content, task outcomes, and participant perceptions of their experience. With communication, actual group size was irrelevant; to the extent that groups chose to cooperate, outcomes were more equal within groups and participants had more positive perceptions. Greater information exchange and negative maintenance talk was related with less equal outcomes and more negative perceptions; more discussion relevant to specific strategy was associated with more equal outcomes. Findings are instructive concerning the genesis and role of group cooperation.
