社会纽带增强了许多群居动物的适应性，使人们对创造社会性个体差异的过程产生了兴趣。以前对雌性狒狒的研究表明，早期生活中的逆境和气质都会影响成年后的社会联系。早期生活中的逆境可能会通过降低投资于社会关系的能力或通过影响作为社会伴侣的吸引力来塑造社会性。我们研究如何女性的早期生活逆境预测野生橄榄狒狒的社会性和气质，并评估是否气质调解早期生活逆境和社会性之间的关系。我们使用31名女性的行为数据来量化社会性。我们衡量互动风格的倾向，产生咕噜声（信号的良性意图）的情况下，发声不产生直接的利益，演员。早期生活的逆境与整体社会性呈负相关，但收到的社会行为比发起的行为更强的预测。经历较少的早期生活逆境的女性有更多的良性互动风格，良性互动风格与接受更多的社会行为有关。互动风格可能部分中介早期生活逆境和社会性之间的关联。这些分析增加了我们对连接早期生活经历和成年社会性的过程的理解。
Social bonds enhance fitness in many group-living animals, generating interest in the processes that create individual variation in sociality. Previous work on female baboons shows that early life adversity and temperament both influence social connectedness in adulthood. Early life adversity might shape sociality by reducing ability to invest in social relationships or through effects on attractiveness as a social partner. We examine how females’ early life adversity predicts sociality and temperament in wild olive baboons, and evaluate whether temperament mediates the relationship between early life adversity and sociality. We use behavioural data on 31 females to quantify sociality. We measure interaction style as the tendency to produce grunts (signals of benign intent) in contexts in which the vocalization does not produce immediate benefits to the actor. Early life adversity was negatively correlated with overall sociality, but was a stronger predictor of social behaviours received than behaviours initiated. Females who experienced less early life adversity had more benign interaction styles and benign interaction styles were associated with receiving more social behaviours. Interaction style may partially mediate the association between early life adversity and sociality. These analyses add to our growing understanding of the processes connecting early life experiences to adult sociality.
