我们的视觉系统建立了物体之间的对应关系，从而使我们能够感知一个物体，比如路上的汽车，不断移动。关于对应的一个核心问题是我们的视觉系统是否使用相对未经处理的基于图像的信息或进一步处理的基于对象的信息来建立对应。虽然已经表明一些基于对象的属性（例如感知亮度）可以影响对应关系，但操纵基于对象的信息通常也至少涉及基于图像的信息的最小变化，使得很难清楚地区分这两个级别。为了避免这种混淆，我们在测量对应性的任务之前操纵基于对象的信息。我们使用 3 元素 Ternus 显示来评估对应性。这些是模糊的视在运动显示，根据对应关系的解决方式，它们被视为一个元素跳过其他元素，或者被视为所有三个元素作为一组一起移动。我们通过在 Ternus 显示之前呈现两个对象历史之一来操纵基于对象的信息。在其中一种情况下，它们独立地移动或改变亮度，因此显得彼此独立。在另一种情况下，元素一起移动或改变其亮度，因此看起来彼此分组。我们发现物体历史确实影响了 Ternus 显示的感知方式，从而证实基于物体的信息本身就可以用作根据基于物体的对应理论建立对应的基础。
Our visual system establishes correspondence between objects and thus enables us to perceive an object, like a car on the road, as moving continuously. A central question regarding correspondence is whether our visual system uses relatively unprocessed image-based information or further processed object-based information to establish correspondence. While it has been shown that some object-based attributes, such as perceived lightness, can influence correspondence, manipulating object-based information typically involves at least minimal changes of image-based information as well, making it difficult to clearly distinguish between the two levels. To avoid this confound, we manipulated object-based information prior to the task in which we measured correspondence. We used 3-element Ternus displays to assess correspondence. These are ambiguous apparent-motion displays that, depending on how correspondence is solved, are perceived as either one element jumping across the others or as all three elements moving together as a group. We manipulated object-based information by presenting one of two object histories prior to the Ternus display. In one, they moved or changed luminance independently, and thus appeared independent from each other. In the other, the elements moved or changed their luminance all together and thus appeared grouped with each other. We found that the object history did influence how the Ternus displays were perceived, thereby confirming that object-based information alone can be used as a basis for establishing correspondence in line with object-based theories of correspondence.
