Abstract: | Patterns of collective movements, such as the distribution of leadership and the organization of individuals, may be either
homogeneously (no leader, no specific order), or heterogeneously (1 or several leaders, and a highly stable order) distributed.
Members of a group need to synchronize their activities and coordinate their movements, despite the fact that they differ
in physiological or morphological traits. The degree of difference in these traits may affect their decision-making strategy.
We demonstrate how a theoretical model based on a variation of a simple mimetic rule, i.e., an amplification process, can
result in each of the various collective movement patterns and decision-making strategies observed in primates and other species.
We consider cases in which 1) the needs of different individuals are identical and social relationships are equivalent between
group members, 2) the needs of individuals are different and social relationships are equivalent, and 3) the needs of individuals
are different and social relationships are different. Finally, 4) we assess how the synergy between 2 mimetism rules, specifically
the probability of joining a movement and that of canceling an initiation, allows group members to stay synchronized and cohesive.
Our models suggest that similar self-organized processes have been selected as reliable and well-adapted means for optimal
collective decisions across species, despite differences in their biological and social characteristics. |
