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（由申请人提供）：我们的视觉体验是一个丰富而详尽的世界，但是在视觉感知中进行了数十年的实验表明，我们可以在任何时候只参加其中的一小部分。传统上，感知理论提出了一个单一的处理流，其中包括一个大规模平行的处理阶段，在选择性瓶颈之后，一个阶段仅限于一个一个或也许是几个对象的阶段。尽管这些理论已经成功地解释了各种实验现象，但一系列最近的研究却质疑这种单个处理流的存在。但是，这些新发现是有争议的。本项目的目的是严格测试这些新观察结果，并在证明可靠的情况下扩展它们。结果将对我们对视觉处理的理解具有深远的影响，并可能协调实验结果与视觉体验之间的冲突。
