Assessing the Perceived Realism of Agent Grouping Dynamics for Adaptation and Simulation

•The average absolute thresholds for group frequency are 15 groups and 36 groups.•The average absolute thresholds for group density are 1.6 agents per group and 3.8 agents per group.•The average optimum configuration for group frequency is 24 groups.•The average optimum configuration for group density is 2.3 agents per group.•There is no change in participant’s responses when measured at the three locations.
