This study investigated the relationship between chronological age and social behavior in 42 adult male and female rhesus macaques (Macaca mulatta) in three specific areas: social interactions, social roles, and social networks. While both old males and old females share behavioral differences associated with senescence, this study reports that old females and old males are distinct in their social behaviors, both from each other and from other adults. Many of these differences appear progressive across age classes, e.g., declining across age classes in females and increasing across age classes in males. Old females are less social and have smaller social networks than other females, while the opposite was found to be true of old males. An explanation for the sex-based differences in aged social behavior and social networks reported in this study may originate in rhesus matrifocal social structure.
本研究调查了42只成年雄性和雌性恒河猴（猕猴）在三个特定领域的实际年龄与社会行为之间的关系：社会互动、社会角色和社会网络。虽然老年雄性和老年雌性都存在与衰老相关的行为差异，但本研究报告称，老年雌性和老年雄性在社会行为上彼此不同，且与其他成年个体也不同。其中许多差异在不同年龄组中呈现出渐进性，例如，在雌性中随年龄组下降，在雄性中随年龄组增加。老年雌性比其他雌性社交性更弱，社交网络更小，而老年雄性则相反。本研究报告的老年社会行为和社会网络中基于性别的差异的一种解释可能源于恒河猴以母系为中心的社会结构。
