Variations in crowding, saccadic precision, and spatial localization reveal the shared topology of spatial vision [Psychological and Cognitive Sciences]

Visual sensitivity varies across the visual field in several characteristic ways. For example, sensitivity declines sharply in peripheral (vs. foveal) vision and is typically worse in the upper (vs. lower) visual field. These variations can affect processes ranging from acuity and crowding (the deleterious effect of clutter on object recognition)...
