What can you see out of “the corner of your eye”? It is common for people to think that peripheral vision is “bad” while central vision is “good”. After all, we are almost constantly moving our eyes to bring different parts of the world into our more-focused central field of view. But it may not be as simple as that. Walking around with paper towel tubes limiting your view to only the “good” central part, for example, would be challenging and frustrating. Instead, this project considers the possibility that central and peripheral vision serve different functional roles in visual perception more generally.This work uses displays that change depending on where a person is looking to isolate what part of the visual field people can see, and then to measure a wide range of basic visual processes across the visual field. It is testing the general hypothesis that central vision is perceptually organized, resulting in representations of the world in terms of 3D objects and surfaces, whereas peripheral vision is perceptually unorganized, resulting in 2D representations that are more like textures than objects. This work can provide explanations for different specific functional deficits that are experienced by individuals with specific visual field loss, such as central loss from macular degeneration or peripheral loss from glaucoma. This project is jointly funded by Perception, Action and Cognition (PAC), the Established Program to Stimulate Competitive Research (EPSCoR), and Smart and Connected Health (SCH).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

你能从“眼角”看到什么？ 人们通常认为周边视觉“不好”，而中央视觉“好”。 毕竟，我们几乎是在不断地移动我们的眼睛，把世界的不同部分带到我们更集中的中心视野中。 但事情可能没有那么简单。 例如，带着纸巾管走来走去，把你的视野限制在“好”的中心部分，这将是一种挑战和沮丧。 相反，该项目考虑的可能性是，中央视觉和周边视觉在更普遍的视觉感知中发挥不同的功能作用。这项工作使用根据人的视线位置而变化的显示器来分离人们可以看到的视野部分，然后测量整个视野中的广泛的基本视觉过程。 它正在测试的一般假设是，中央视觉是感知组织的，导致在3D物体和表面方面的世界表示，而周边视觉是感知无组织的，导致2D表示更像纹理而不是物体。 这项工作可以为具有特定视野损失的个体所经历的不同特定功能缺陷提供解释，例如黄斑变性的中心损失或青光眼的周边损失。该项目由感知、行动和认知（PAC）、激励竞争研究的既定计划（EPSCoR）和智能与互联健康（SCH）共同资助。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
