Visual agnosia

by Martha J Farah

A landmark study of visual agnosia, a term "that refers to a multitude of different disorders and syndromes ... Some patients cannot recognize faces but can still recognize other objects, while others retain only face recognition. Some see only one object at a time; others can see multiple objects but recognize only one at a time. Some do not consciously perceive the orientation of an object but nevertheless reach for it with perfected oriented grasp; others do not consciously recognize a face as familiar but nevertheless respond to it automatically. Each disorder is illustrated with a clinical vignette, followed by a thorough review of the case report literature and a discussion of the theoretical implications of the disorder for cognitive neuroscience."--Back cover.
