许多物种使用不同的认知机制朝向特定的位置以到达重要的资源。其中一些，如路径整合，现在已经很好地理解了，但非人类灵长类动物运动的认知定向机制仍然是争论的主题。为了研究查克玛狒狒的运动是否与欧几里得或拓扑空间意识更一致，我们研究了狒狒是否重复使用相同的路径网络，并测试了三个预测结果，从假设使用欧几里得和拓扑空间意识。我们记录了一组狒狒在南非Soutpansberg山脉234整天和137部分天的测距行为。结果表明，我们的狒狒通过一个密集的重复路线网络旅行。在导航这个路线网络时，狒狒并没有从所有方向接近旅行目标，而是从少数相同的方向接近它们，支持拓扑空间意识。当离开旅行目标时，狒狒的初始旅行方向与下一个旅行目标的方向明显不同，再次支持拓扑空间意识。虽然我们发现狒狒在核心区域和在其活动范围的外围区域的活动具有相似的线性，但这并不能为欧几里得空间意识的存在提供确凿的证据，因为狒狒可能已经积累了类似于核心区域的外围知识。总的来说，我们的发现支持了狒狒使用拓扑地图导航的假设。
Many species orient towards specific locations to reach important resources using different cognitive mechanisms. Some of these, such as path integration, are now well understood, but the cognitive orientation mechanisms that underlie movements in non-human primates remain the subject of debate. To investigate whether movements of chacma baboons are more consistent with Euclidean or topological spatial awareness, we investigated whether baboons made repeated use of the same network of pathways and tested three predictions resulting from the hypothesized use of Euclidean and topological spatial awareness. We recorded ranging behaviour of a group of baboons during 234 full days and 137 partial days in the Soutpansberg Mountains, South Africa. Results show that our baboons travelled through a dense network of repeated routes. In navigating this route network, the baboons did not approach travel goals from all directions, but instead approached them from a small number of the same directions, supporting topological spatial awareness. When leaving travel goals, baboons' initial travel direction was significantly different from the direction to the next travel goal, again supporting topological spatial awareness. Although we found that our baboons travelled with similar linearity in the core area as in the periphery of their home range, this did not provide conclusive evidence for the existence of Euclidean spatial awareness, since the baboons could have accumulated a similar knowledge of the periphery as of the core area. Overall, our findings support the hypothesis that our baboons navigate using a topological map.
