Abstract

Primates must balance the need to monitor other conspecifics to gain social information while not losing other resource opportunities.

We consolidate evidence across the fields of primatology, psychology, and neuroscience to examine individual, population, and species differences in how primates, particularly macaques, monitor conspecifics.

We particularly consider the role of serotonin in mediating social competency via social attention, aggression, and dominance behaviors

Finally, we consider how the evolution of variation in social tolerance, aggression, and social monitoring might be explained by differences in serotonergic function in macaques.
