ABSTRACT
The survival of human and other primate groups depends on the group’s ability to remain together by coordinating the varying preferences of its members. Studies have shown that decisions in groups are achieved in a variety of manners, being made by consensus involving a majority of group members and sometimes being dictated by a single group member or a small subset of the group. Consensus decisions—widespread decisions reached by the group as a whole—once taken, require that group members become informed about how to cohesively behave. Members of small groups become informed of the consensus decision on how to behave by globally observing the other group members’ behaviour. Flocking behavior is observed in many group-living animals, that is, bird flocks, aquatic shoals, and herds of ungulates. The simulation results fit the empirical statistics very well, confirming the effectiveness of the proposed group-cohesion mobility model.
