To provide a mechanistic explanation of how group size influences collaborative problem-solving performance across different levels of task complexity and information-sharing conditions.
Developed an agent-based simulation model simulating collaborative group decision-making during problem-solving tasks.
Modeled agents iteratively conducting individual local searches, proposing and evaluating solution candidates, and updating problem representations based on peer input.
Evaluated performance dynamics across varying group sizes, communication efficacy levels, and three problem complexity tiers (low, medium, and high).
With ineffective information sharing, larger group size negatively correlated with early performance across all task complexity levels.
Over time, larger groups matched smaller groups on low-complexity tasks and outperformed them on medium-complexity tasks due to greater solution diversity, but struggled on high-complexity tasks due to excessive disagreement.
Effective information sharing improved outcomes across all group sizes and yielded the greatest performance enhancements in larger groups.
