Quasi-Perceptual Margins in Homogeneously Stimulated Fields

Abstract

If one wants to describe the visual world as it appears at a given time, one can simply enumerate and describe the objects located in the perceptual space. This is certainly the most natural and spontaneous description that a naive observer could give. If one adopts a more critical or analytical attitude—without leaving the phenomenological domain—one could describe the very same visual world not as made of objects, but as constituted of a given number of different lines and variously colored surfaces.
