Group Problem Solving

This chapter explores research on group memory, which is important in itself and is also frequently a necessary preliminary process for further group problem solving. Research on group recognition memory indicates that group memory is better than the memory of the average individual. Assigning different information to be learned by different group members is more effective than having all members learn all information. Meanwhile, research on shared versus unshared information indicates that groups are more likely to make correct decisions when they believe they are solving a problem rather than making a judgment. Lastly, research on the common knowledge effect demonstrates that the more group members who know an item of information before discussion, the greater the impact of that information on both group judgment and group choice. This indicates the importance of supportive group memory on tasks that have correct answers which are difficult to demonstrate.
