The Binding Ring Illusion: assimilation affects the perceived size of a circular array.

ABSTRACT: Our perception of an object's size arises from the integration of multiple sources of visual information including retinal size, perceived distance and its size relative to other objects in the visual field. This constructive process is revealed through a number of classic size illusions such as the Delboeuf Illusion, the Ebbinghaus Illusion and others illustrating size constancy. Here we present a novel variant of the Delbouef and Ebbinghaus size illusions that we have named the Binding Ring Illusion. The illusion is such that the perceived size of a circular array of elements is underestimated when superimposed by a circular contour - a binding ring - and overestimated when the binding ring slightly exceeds the overall size of the array. Here we characterize the stimulus conditions that
