生态学上最有意义的事件，包括物体的运动，都发生在与表面有关的地方或表面上。我们在地面上沿着跑，汽车在公路上行驶，球在草坪上滚动，等等，尽管还有其他的运动，如鸟的飞行，但很可能沿着表面的运动更频繁，也更有生物学意义。要检查是否发生在有关的事件表面有一个首选的状态，在视觉表示方面，我们问的现象，明显的运动是否会表现出偏好的运动附着到表面。我们使用了一个有竞争力的三维运动范例2，发现有一个偏好，看到运动之间的令牌放置在相同的差距，而不是不同的飞机。为了支持我们的表面布局假设，视差的影响可以通过倾斜标记来消除，这样它们都可以在同一个表面平面内看到，或者通过插入一个倾斜的背景表面来消除。此外，高度弯曲的立体表面导致由该表面定义的更迂回的运动路径的感知，而不是三维空间中的最短路径。
THE most meaningful events ecologically, including the motion of objects, occur in relation to or on surfaces1. We run along the ground, cars travel on roads, balls roll across lawns, and so on. Even though there are other motions, such as flying of birds, it is likely that motion along surfaces is more frequent and more significant biologically. To examine whether events occurring in relation to surfaces have a preferred status in terms of visual representation, we asked whether the phenomenon of apparent motion would show a preference for motion attached to surfaces. We used a competitive three-dimensional motion paradigm2 and found that there is a preference to see motion between tokens placed within the same disparity as opposed to different planes. Supporting our surface-layout hypothesis, the effect of disparity was eliminated either by slanting the tokens so that they were all seen within the same surface plane or by inserting a single slanted background surface upon which the tokens could rest. Additionally, a highly curved stereoscopic surface led to the perception of a more circuitous motion path defined by that surface, instead of the shortest path in three-dimensional space.
