Case Studies in the Neuropsychology of Vision

Within the field of vision, case studies of patients with selective deficits have helped develop our understanding of how basic properties of images are processed (color, motion), how such properties are integrated into perception, and how perceptual processes relate to recognition and imagery. This book provides reviews of major case studies dealing with the breakdown of visual perception and recognition. The case studies are discussed in the light of subsequent studies and the chapters provide a context in which the contributions of the case studies can be evaluated. Disorders of motion vision, color vision, perceptual integration, perceptual classification, recognition of particular categories of object, semantic access from vision (in optic aphasia), and recognition impairments with relative sparing of imagery are covered.
