在许多物种中，通过布局几何来进行空间定向，但其潜在机制仍存在争议。一些人认为，动物的位置感是基于几何计算而非三维表示，另一些人则认为，这取决于全景图像匹配过程。因为儿童是通过微妙的三维地形扰动来重新定位的，而不是通过表面或独立柱子上明显的二维亮度轮廓来重新定位的，所以儿童的地方感不能用图像匹配来解释。为了在不同物种中验证图像匹配理论，本实验研究了家养雏鸡（Gallus Gallus）在与儿童相似的环境中重新定位的表现。小鸡和孩子一样，会根据微妙的三维地形的几何关系自发地重新定向，而不是根据表面或柱子上明显的二维亮度轮廓。这些发现为人类和其他脊椎动物的同源导航系统提供了证据，并对这些物种重新定位的图像匹配理论提出了质疑。
Spatial reorientation by layout geometry occurs in numerous species, but its underlying mechanisms are debated. While some argue that navigating animals' sense of place is based on geometric computations over three-dimensional representations, others claim it depends on panoramic image-matching processes. Because children reorient by subtle three-dimensional perturbations of the terrain and not by salient two-dimensional brightness contours on surfaces or freestanding columns, children's sense of place cannot be explained by image matching. To test image-matching theories in a different species, the present experiment investigates the reorientation performance of domestic chicks (Gallus gallus) in environments similar to those used with children. Chicks, like children, spontaneously reoriented by geometric relationships of subtle three-dimensional terrains, and not by salient two-dimensional brightness contours on surfaces or columns. These findings add to the evidence for homologous navigation systems in humans and other vertebrates, and they cast doubt on image-matching theories of reorientation in these species.
