在 5 个实验中，我们发现，当 2 个轮廓属于 2 个物体而不是 1 个物体时，判断 2 个轮廓的相对位置会更加困难。即使 1 个物体和 2 个物体的显示在物理上相同，也可以观察到这一点，而感知集决定了它们被视为包含多少个物体。这样的 2 对象成本与基于对象的注意力视图以及位置编码的分层方案一致，其中对象部分相对于其父对象的位置进行定位。在进一步的实验中，结果表明，根据这种分层方案，物体的相对位置可能会干扰物体部分相对位置的判断，但相反的情况并没有发生。即使当判断零件的相对位置比判断物体的相对位置更快时，也发现了这一点。
In 5 experiments, it was found that judging the relative location of 2 contours was more difficult when they belonged to 2 objects rather than 1. This was observed even when the 1- and 2-object displays were physically identical, with perceptual set determining how many objects they were seen to contain. Such a 2-object cost is consistent with object-based views of attention and with a hierarchical scheme for position coding, whereby object parts are located relative to the position of their parent object. In further experiments, it was shown that in accord with this hierarchical scheme, the relative location of objects could disrupt judgments of the relative location of object parts, but the reverse did not occur. This was found even when the relative position of the parts could be judged more quickly than that of the objects.
