/ P) K; r1 |5 c3.17 Predictably, space-dependent communication is less effective than space-independent communication. The effect varies as a function of group size. In groups of 50 individuals, there is only a small deterioration in performance compared to groups with space-independent communication. In groups of 10 individuals, however, space-limited communication results in much worse performance. The reason is that with space-dependent communication information takes longer to reach all the individuals in a group. Given an environment of a certain size, individuals in large groups tend to be closer to one another because of their greater density. As a result, the negative effects of space-dependent communication are limited. By contrast, small groups tend to be more dispersed and information takes longer to reach all the individuals in the group. |
