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.

猕猴监视他人的方式的差异：血清素是否起着核心作用？

灵长类动物必须平衡监视其他物种以获得社会信息的需求，同时又不失去其他资源机会。我们整合了灵长类动物学，心理学和神经科学领域的证据，以研究灵长类动物（尤其是猕猴）监测物种的方式的个体，种群和物种差异。我们特别考虑了5-羟色胺在通过社会关注，攻击和主导行为来介导社会能力中的作用。最后，我们考虑如何通过猕猴的血清素能功能的差异来解释社会容忍度，攻击性和社会监控度的变化演变。
