Abstract

As the third solution to group dispersion, Dunbar proposes primates use several higher order cognitive skills to especially manage ‘weak ties’ in a nuanced and fast-tracked way, therewith avoiding unnecessary conflicts. We here argue that subconscious, automatic processes including attention allocation and behavioral or neurophysiological state matching can serve a similar function in maintaining group cohesion.
