Filling-In: From Perceptual Completion to Cortical Reorganization

Luiz Pessoa and Peter De Weerd

Abstract

A well-known example of filling-in involves the blind spot, a region in the back of the eye that is devoid of photoreceptors. The term blind spot is somewhat of a misnomer, because the corresponding region of visual space is not simply perceived as dark, as one would expect. Instead, it is “filled-in” with the same color and texture as the surrounding background. This phenomenon is often considered as little more than a curiosity. However, this book argues that completion mechanisms similar to those that fill in the blind spot are pervasive and necessary for normal perception. The book reviews ... More

Keywords: blind spot, photoreceptors, visual space, color, texture, perception, auditory system, somatosensory system, motor system
