社会关系的质量代表了两个人之间过去社会交往的历史，从中可以预测未来交往的性质和结果。目前的理论预测，关系质量包括三个独立的组成部分，它的价值，兼容性和安全性。这项研究是第一次调查的组成部分，关系质量在一个大脑鸟。最近使用的方法，以获得每个关系的质量组件在黑猩猩，Pan troglodytes的定量测量，我们输入的数据从一组11只乌鸦，乌鸦corax，到主成分分析的7个行为变量。提取的组成部分的特征与价值、兼容性和安全性方面的预测相匹配，并被贴上了标签。当亲属关系和性别组合对每个关系质量组件的影响进行了分析，我们发现，亲属有更有价值的关系，而女性有较少的安全和兼容的关系，虽然兼容性的性别组合的影响只适用于非亲属。这些模式与我们从鸟舍研究中获得的关于乌鸦关系的少量知识是一致的，并表明乌鸦关系质量的组成部分确实与黑猩猩相似。(C)2010年，动物行为研究协会。由爱思唯尔有限公司发布。保留所有权利。
The quality of a social relationship represents the history of past social interactions between two individuals, from which the nature and outcome of future interactions can be predicted. Current theory predicts that relationship quality comprises three separate components, its value, compatibility and security. This study is the first to investigate the components of relationship quality in a large-brained bird. Following methods recently used to obtain quantitative measures of each relationship quality component in chimpanzees, Pan troglodytes, we entered data on seven behavioural variables from a group of 11 ravens, Corvus corax, into a principal components analysis. The characteristics of the extracted components matched those predicted for value, compatibility and security, and were labelled as such. When the effects of kinship and sex combination on each relationship quality component were analysed, we found that kin had more valuable relationships, whereas females had less secure and compatible relationships, although the effect of sex combination on compatibility only applied to nonkin. These patterns are consistent with what little knowledge we have of raven relationships from aviary studies and show that the components of relationship quality in ravens may indeed be analogous to those in chimpanzees.
