自然场景包含隐藏区域或遮挡，这在两只眼睛中是不同的，从而导致只能由一只眼睛看到的单眼区域。这样的单眼区域似乎没有被抑制，但似乎被集成到场景中。在这里，我们将探讨如何将两只眼睛的视图结合起来，以表示包含单眼区域的场景，这些区域部分隐藏在前景遮挡“栅栏”后面。“我们测量了包含不同量的双目和单眼信息的场景的密度/数量辨别任务的性能。我们发现，从一些单独的单眼区域的信息可以集成到我们的整体概念的点密度/数量，虽然不同的观察者使用不同的策略。然而，如果单眼和双眼的信息都存在，观察者似乎忽略了纯粹的单眼区域，仅依赖于双眼的信息时，作出密度/数量判断。我们的工作表明，双目区域比单眼区域更受青睐，这样当双目区域存在于场景中时，来自单眼区域的信息被有效地忽略。
Natural scenes contain hidden regions, or occlusions, that differ in the two eyes, resulting in monocular regions that can only be seen by one eye. Such monocular regions appear to not be suppressed but seem to be integrated into the scene percept. Here we explore how the two eyes' views are combined to represent a scene that contains monocular regions, partially hidden behind a foreground occluding "fence." We measured performance in a density/numerosity discrimination task for scenes containing differing amounts of binocular and monocular information. We find that information from a number of separate monocular regions can be integrated into our overall percept of dot density/numerosity, although different observers use different strategies. If, however, both monocular and binocular information is present, observers appear to ignore the purely monocular regions, relying solely on the binocular information when making density/numerosity judgments. Our work suggests that binocular regions are favored over monocular regions, such that information from monocular regions is effectively ignored when binocular regions are present in a scene.
