社会复杂性假说认为，生活在大型社会群体中的动物应该在沿着可预测的维度上表现出更强的认知能力。为了验证这一概念，我们比较了高度社会化的松鸦，Gymnorhinus cyanocephalus，相对非社会化的西方灌丛鸦，Aphelocoma californica，在两个复杂的认知任务相关的能力，跟踪和评估社会关系。松鸦学会了跟踪多个二元关系更迅速，更准确地比灌丛鸦，并显示出更强大，更准确的传递性推理机制。这些结果清楚地证明了动物的社会复杂性和认知之间的联系。(C)2003年由Elsevier Science Ltd代表动物行为研究协会出版。
The social complexity hypothesis asserts that animals living in large social groups should display enhanced cognitive abilities along predictable dimensions. To test this concept, we compared highly social pinyon jays, Gymnorhinus cyanocephalus, with relatively nonsocial western scrub-jays, Aphelocoma californica, on two complex cognitive tasks relevant to the ability to track and assess social relationships. Pinyon jays learned to track multiple dyadic relationships more rapidly and more accurately than scrub-jays and appeared to display a more robust and accurate mechanism of transitive inference. These results provide a clear demonstration of the association between social complexity and cognition in animals.
