从蚂蚁到人类，迷失方向的动物会根据周围表面布局的形状进行重新定位：这种行为模式长期以来一直被视为对布局几何形状敏感的证据。然而，最近的计算模型表明，重新定向过程可能不依赖于几何分析，而是依赖于环境2D图像中亮度轮廓的匹配。在这里，我们通过调查幼儿在封闭环境中的重新定向来检验这一观点。孩子们被3D布局极其微妙的几何特性重新定位：凸起和隆起只略微伸出地板，产生对比度较低的边缘。此外，在没有独特3D结构的连续布局中，儿童无法通过突出的亮度轮廓重新定位。这一发现为几何布局表征支持儿童重新定向提供了证据。
Disoriented animals from ants to humans reorient in accord with the shape of the surrounding surface layout: a behavioral pattern long taken as evidence for sensitivity to layout geometry. Recent computational models suggest, however, that the reorientation process may not depend on geometrical analyses but instead on the matching of brightness contours in 2D images of the environment. Here we test this suggestion by investigating young children's reorientation in enclosed environments. Children reoriented by extremely subtle geometric properties of the 3D layout: bumps and ridges that protruded only slightly off the floor, producing edges with low contrast. Moreover, children failed to reorient by prominent brightness contours in continuous layouts with no distinctive 3D structure. The findings provide evidence that geometric layout representations support children's reorientation.
