在一系列的四个实验中，黑猩猩，Pan troglodytes，被赋予两个认知任务，一个物体选择任务和一个辨别任务（基于位置），每个任务都在合作或竞争的背景下进行。在这两项任务中，黑猩猩在竞争时比在合作时表现得更熟练，有证据表明，与同种的竞争在辨别位置任务中特别容易。这是第一个在单一实验范式中证明竞争促进认知效应的研究。我们认为，黑猩猩的认知进化是最好的理解在其社会生态背景。(C)2004年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
In a series of four experiments, chimpanzees, Pan troglodytes, were given two cognitive tasks, an object choice task and a discrimination task (based on location), each in the context of either cooperation or competition. In both tasks chimpanzees performed more skilfully when competing than when cooperating, with some evidence that competition with conspecifics was especially facilitatory in the discrimination location task. This is the first study to demonstrate a facilitative cognitive effect for competition in a single experimental paradigm. We suggest that chimpanzee cognitive evolution is best understood in its socioecological context. (C) 2004 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.
