在互动的群体成员网络中形成的社会关系可以对个人的行为和健康产生深远的影响。然而，我们对个人如何看待他们的关系以及这种看法与我们的外部互动衡量标准之间的关系知之甚少。我们使用社交网络分析和回放实验，研究了两组圈养的和尚鹦鹉（Myiopsitta monachus，n = 21 和 19）在二元和新兴社会层面上对亲和关系和竞争关系的感知。在二元社会尺度上，个体对亲密伙伴的攻击性较小，而对非伙伴邻居的攻击性则较多。在新兴的社会尺度上，不同社会背景下的关系之间不存在关联，个人的主导地位与其受欢迎程度并不相关。回放反应模式主要由二元尺度的附属社会背景中的关系驱动。在两组中，个体对回放实验的反应都受到二元社会尺度上强烈的隶属关系的显着影响，尽管两组中的方向不同。反应模式也受到新兴社会规模中亲缘关系的影响，但仅限于两组中的一组。在亲和关系中，两个群体中的个体都会感知二元社会尺度的关系，但新兴社会尺度的关系只影响一组的反应。这些结果提供了初步证据，表明在圈养的和尚鹦鹉群体中，亲和社会背景中的关系可能被认为比竞争关系更重要。我们的方法可用于广泛的社会物种，比较分析可以提供重要的见解，了解个人如何看待跨社会背景和社会规模的关系
Social relationships formed within a network of interacting group members can have a profound impact on an individual's behavior and fitness. However, we have little understanding of how individuals perceive their relationships and how this perception relates to our external measures of interactions. We investigated the perception of affiliative and agonistic relationships at both the dyadic and emergent social levels in two captive groups of monk parakeets (Myiopsitta monachus, n = 21 and 19) using social network analysis and playback experiments. At the dyadic social scale, individuals directed less aggression towards their strong affiliative partners and more aggression towards non-partner neighbors. At the emergent social scale, there was no association between relationships in different social contexts and an individual's dominance rank did not correlate with its popularity rank. Playback response patterns were mainly driven by relationships in affiliative social contexts at the dyadic scale. In both groups, individual responses to playback experiments were significantly affected by strong affiliative relationships at the dyadic social scale, albeit in different directions in the two groups. Response patterns were also affected by affiliative relationships at the emergent social scale, but only in one of the two groups. Within affiliative relationships, those at the dyadic social scale were perceived by individuals in both groups, but those at the emergent social scale only affected responses in one group. These results provide preliminary evidence that relationships in affiliative social contexts may be perceived as more important than agonistic relationships in captive monk parakeet groups. Our approach could be used in a wide range of social species and comparative analyses could provide important insight into how individuals perceive relationships across social contexts and social scales
