In almost all non-human primate species kinship, sex and rank bias the patterning of interactions among subjects, seemingly in a way that favours the individual's fitness. A number of studies have been done in order to study separately the effects of these variables, concluding that an adequate model of interactions cannot be developed assuming preponderance of a single variable. The 'willingness' of one animal to interact with another can be explained as the result of assessing the possible outcomes (proximate and/or ultimate) of the interaction. The interrelationship of variables such as kinship, sex and rank, among others, provides the actors with a basis for deciding their rates of social interactions. The following study was done to assess whether kinship, rank and sex exerted independent, additive effects in the within-group distributions of eight social behaviour categories of captive groups of stump-tailed macaques. We found that the three variables synergistically affected the patterning of all behavioural categories. This suggests that the pay-offs of social interactions do not vary linearly, being intrinsically correlated with the actors' attributes so that uncertainty in the choice of a potential partner is minimized.
在几乎所有非人类灵长类动物物种中，亲属关系、性别和等级会使个体间的互动模式产生偏差，似乎是以一种有利于个体适应性的方式。为了分别研究这些变量的影响，已经开展了多项研究，得出的结论是，假设单一变量占主导地位，就无法建立一个合适的互动模型。一只动物与另一只动物互动的“意愿”可以解释为评估互动可能结果（近因和/或终极结果）的结果。亲属关系、性别和等级等变量之间的相互关系为行为主体提供了决定其社会互动频率的依据。下面这项研究旨在评估亲属关系、等级和性别在圈养短尾猕猴群体的八个社会行为类别组内分布中是否发挥独立的累加效应。我们发现这三个变量对所有行为类别的模式都有协同影响。这表明社会互动的回报并非呈线性变化，而是与行为主体的属性内在相关，从而将选择潜在伙伴时的不确定性降至最低。
