我们的视觉系统主要依靠图像的表面边界轮廓，巧妙地将部分遮挡的表面的可见部分与被遮挡的部分（模态表面补全）整合在一起。鲜为人知的是，视觉系统是否也利用表面特征信息，如亮度对比极性，进行表面补全。我们进行了三个实验来研究这个问题。实验1发现，当具有相同亮度对比极性的部分遮挡矩形的可见部分移动到遮挡面后面时，观察者将可见部分视为被遮挡矩形的一部分，在遮挡面后面紧密移动。然而，当可见部分具有相反的亮度对比极性时，几乎无法感知到部分的整体运动，这表明模态曲面整合失败。实验2表明，同样的亮度对比极性约束适用于没有明确遮挡表面图像的显示器的模态表面积分。实验3表明，部分遮挡矩形可见段的形状和亮度对比极性都影响模态曲面补全。总之，这些发现表明，亮度对比极性，以及表面边界轮廓，是模态表面积分的重要线索。
Our visual system ably integrates the visible parts of a partially occluded surface with the occluded parts (amodal surface completion), mainly by relying on the surface boundary contours of the image. Less known, is whether the visual system also utilizes surface feature information, such as luminance contrast polarity, for surface completion. We conducted three experiments to investigate this issue. Experiment 1 found that when visible segments of a partially occluded rectangle with the same luminance contrast polarity move behind an occluding surface, observers perceive the visible segments as part of the occluded rectangle moving cohesively behind the occluding surface. However, when the visible segments have opposite luminance contrast polarity, the global motion of the segments is barely perceived, suggesting a failure of amodal surface integration. Experiment 2 revealed that this same luminance contrast polarity constraint applies to amodal surface integration of a display without an explicit occluding surface image. Experiment 3 showed that both the shape and luminance contrast polarity of the visible segments of the partially occluded rectangle affect amodal surface completion. Together, these findings demonstrate that luminance contrast polarity, along with surface boundary contour, are important cues for amodal surface integration.
