Crowding, Patterns and the Fundamentals of Vision
Abstract:
In most models of vision, low level visual tasks are explained by low
level neural mechanisms. For example, in crowding, perception of a
target is impeded by nearby elements because, as proposed, responses of
neurons coding for nearby elements are pooled. Indeed, performance
deteriorated when a vernier stimulus was flanked by two lines, one on
each side. However, performance improved strongly when the lines were
extended to squares. Classic models cannot explain this uncrowding
