场景中的物体通常被部分遮挡，而不会给观察者带来任何问题：被遮挡的部分显然是通过非模态完成来表示的。为了评估人类感知和记忆部分遮挡图片的能力，我们使用快速串行视觉呈现（RSVP）显示了持续时间为53毫秒，107毫秒，213毫秒或426毫秒/图片的图片序列。参与者要么试图发现一个命名的目标（例如，“商人在桌子上”）或给予一个是-否识别记忆测试的一个项目。在实验1中，覆盖了多达30%的图片区域，检测和识别都远远高于机会。更有趣的是，遮挡显著影响识别记忆，但不影响目标检测。在实验2中，当图片被倒置时，遮挡损害检测严重识别。对于目标检测，遮挡和反转之间的相互作用是显着的。相比之下，拿走颜色信息并没有显着降低检测的闭塞的容忍度（实验3）。最后，实验4表明，40%的图片区域被遮挡，检测性能受损。这些结果支持的假设，上下文主旨信息促进视觉过程，容忍阻塞噪声。虽然倒装和颜色的测试，特别是，所提出的范式也可以用来调查的作用，其他因素的主旨表示。
Objects in a scene are often partially occluded without causing the viewer any problem: the occluded parts are apparently represented via amodal completion. To evaluate human ability to perceive and remember partially occluded pictures, we showed sequences of pictures using rapid serial visual presentation (RSVP) for durations of 53 ms, 107 ms, 213 ms, or 426 ms/picture. Participants either attempted to detect a named target (eg,“businessmen at table”) or were given a yes–no recognition memory test of one item. In Experiment 1, with as much as 30% of the picture area covered, detection and recognition were both well above chance. More interestingly, occlusion significantly affected recognition memory but not target detection. In Experiment 2, when pictures were inverted, occlusion impaired detection as severely as recognition. For target detection, the interaction between occlusion and inversion was significant. By contrast, taking away color information did not significantly reduce detection's tolerance of occlusion (Experiment 3). Finally, Experiment 4 showed that with 40% of the picture area occluded, detection performance was impaired. These results support the hypothesis that contextual gist information facilitates visual processes that tolerate occluding noise. Although inversion and color were tested in particular, the presented paradigm can also be used to investigate the role of other factors in gist representation.
