Primates are known to have considerable knowledge about the social relationships that link their group mates and are likely to derive this information from observing the social interactions that occur in their social group. They may, therefore, be hypothesized to pay particular attention to the social interactions involving group mates. In this study, we evaluated how the attention captive mandrills (Mandrillus sphinx) devote to their group mates was modulated by the behavior of the latter. Mandrills looked most frequently at foraging individuals and least frequently at sleeping individuals. Mandrills also looked at grooming individuals more than at individuals that were simply sitting in contact. Grooming dyads were looked at regardless of the social rank and kinship of the individuals involved. These results contribute to our understanding of how primates obtain their social knowledge.
灵长类动物被认为对与其群体成员相关的社会关系有着相当的了解，并且可能通过观察其社会群体中发生的社会互动来获取这些信息。因此，他们可能会特别关注涉及群体成员的社会互动。在这项研究中，我们评估了圈养的山魈（Mandrillus sphinx）对其群体成员的关注程度如何受到后者行为的调节。山魈最常观察到觅食个体，最不常观察到睡眠个体。山魈也比只是坐在接触状态下的个体更多地观察到正在梳理毛发的个体。无论涉及的个体的社会等级和亲缘关系如何，梳理的对偶体都会被观察到。这些结果有助于我们理解灵长类动物如何获得其社会知识。
