当我们观看部分被遮挡的物体时，我们如何有效地整合落在我们眼睛上的不连贯的图像片段？我们使用心理物理阈值求和技术来解决这个问题，通过测量物理碎片但感知完整的对象的孤立和组合特征的辨别表现。如果视觉完成可以促进卓越的集成效率，那么我们预计视觉完成的对象的性能将超过单独显示的各个对象部分的性能预期。与这一预测相反，我们发现物理碎片但感知完整的物体的静态和移动版本的辨别性能明显低于其组成部分的性能预期。这些结果对未来的视觉完成理论提出了挑战。
How efficiently do we integrate across the disconnected image fragments that fall upon our eyes when we view partly occluded objects? We used a psychophysical summation-at-threshold technique to address this question by measuring discrimination performance with both isolated and combined features of physically fragmented but perceptually complete objects. If visual completion promotes superior integration efficiency, we would expect performance with a visually completed object to exceed what would simply be expected from performance with the individual object parts shown in isolation. Contrary to this prediction, we find that discrimination performance with both static and moving versions of physically fragmented but perceptually complete objects is significantly worse than would be expected from performance with their constituent parts. These results present a challenge for future theories of visual completion.
