在四个实验中，作者检查了边缘的地面解释可能获得形状描述的程度。这些实验利用了形状在随后的实验中对知觉判断产生的启动效应。当图形形状与前一次试验相同时，错误率和反应时间都有明显的降低。这种重复启动效应可能是由于激活了前一次试验中剩余的图形的形状描述。相比之下，即使在两次试验之间图形的对比符号颠倒时，也没有看到地面形状的启动。对图形形状的启动发生在一个相对抽象的水平上，因为它在对比度和方向的反转中是健壮的。这些数据表明，对形状的图形解释得到了形状描述，但地面没有。
In four experiments, the authors examined the extent to which the ground interpretation of an edge may receive a shape description. These experiments used the priming effect that shapes have on perceptual judgments on a subsequent trial. A robust reduction in error rates and reaction times was seen when the figural shape was the same as that on the previous trial. This repetition priming effect may be due to activation of the shape description of the figure that remained from the previous trial. In contrast, no priming by the shape of the ground was seen even when the contrast sign of the figure reversed between trials. Priming for figural shapes occurred at a relatively abstract level because it was robust across reversals of contrast and orientation. These data suggest that the figural interpretation of a shape receives a shape description but that the ground does not.
