三角形完成（即完成三角形的两条腿后回到起点）是一种广泛使用的方法，用于检查动物和人类的路径整合能力。两个实验中，归巢被用来检查纯粹的视觉机制（如光流）的空间信息编码和集成的效率。成年观察者必须在交互式模拟的三维环境中完成三角形，该环境由两个关键物体和一组均匀的白色圆柱体作为背景组成。每个参与者完成了27个三角形，对应于三个几何视野（40°，60°或80°）和九个三角形布局（第一个转角和第二条腿的变化）的阶乘组合。寻的性能显示三角形布局的强烈影响，但没有效果的几何领域的观点：同时可见的空间信息量的变化并没有影响空间知识的获取所使用的环境。将编码误差模型应用于数据，揭示了在视觉模拟环境中移动时拾取方向信息的严重系统误差。这些结果进行了讨论的情况下，纯粹的视觉和非视觉导航空间之间的信息差异。
Triangle completion (ie homing to the starting point after completing two legs of a triangle) is a widely used method for examining path-integration abilities in animals and humans. Two experiments are reported in which homing was used to examine the efficiency of purely visual mechanisms (eg optical flow) for spatial-information coding and integration. Adult observers had to complete triangles in an interactively simulated three-dimensional environment which consisted of two critical objects and a homogeneous set of white cylinders serving as background. Each participant completed twenty-seven triangles corresponding to a factorial combination of three geometrical fields of view (40°, 60°, or 80°) and nine triangle layouts (with variations of the first turning angle and the second leg). Homing performances revealed strong effects of triangle layout, but no effect of geometrical fields of view: variations in the amount of simultaneous visible spatial information did not influence the acquisition of spatial knowledge in the environments used. Applying the encoding-error model to the data revealed severe systematic errors of picking up directional information while moving through visually simulated environments. These results are discussed with respect to informational differences between situations of purely visual and nonvisual navigations in space.
