DESCRIPTION (provided by applicant): Our visual experience is of a rich, detailed world, yet decades of experiments in visual perception demonstrate that we can attend to only a small portion of it at any one time. Traditionally, theories of perception have posited a single processing stream that includes a massively parallel processing stage followed, after a selective bottleneck, by a stage limited to the processing of one or, perhaps, a few objects at a time. While such theories have successfully explained a variety of experimental phenomena, a series of recent studies have called into question the existence of this single processing stream. However, these new findings are controversial. The goal of the present project is to rigorously test these new observations and to extend them if they prove reliable. The results will have far-reaching implications for our understanding of visual processing, potentially reconciling the conflict between experimental results and visual experience.

描述(申请人提供)：我们的视觉体验是一个丰富、详细的世界，然而几十年的视觉感知实验表明，我们在任何时候都只能关注其中的一小部分。传统上，知觉理论假设一个单一的处理流，它包括一个大规模并行的处理阶段，在一个选择性的瓶颈之后，紧随其后的是一个阶段，一次只能处理一个或几个物体。虽然这些理论已经成功地解释了各种实验现象，但最近的一系列研究对这种单一加工流的存在提出了质疑。然而，这些新发现是有争议的。本项目的目标是严格测试这些新的观察结果，并在它们被证明是可靠的情况下推广它们。这些结果将对我们对视觉处理的理解产生深远的影响，潜在地调和实验结果和视觉体验之间的冲突。
