内容简介：
One important means to understanding normal cognitive functions is the study of the breakdown of these functions following brain damage. 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 (colour, motion), how such properties are integrated in 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, with the case studies being discussed in the light of studies that have followed since. The chapters provide a context in which the contributions of the case studies can be evaluated. The case studies include disorders of motion vision, colour 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.
