Visual agnosia is a rare but fascinating disorder of visual object recognition that can occur after a brain lesion. This book documents the case of John, who worked intensively with the authors for 26 years after acquiring visual agnosia following a stroke. It revisits John’s case over twenty years after it was originally described in the book To See But Not To See, in 1987. As in the previous book, the condition is illuminated by John and his wife, Iris, in their own words. A Case Study in Visual Agnosia Revisited discusses John’s case in the context of research into the cognitive neuroscience of vision over the past twenty years. It shows how John’s problems in recognition can provide important insights into the way that object recognition happens in the brain, with the results obtained in studies of John’s perception being compared to emerging work from brain imaging in normal observers. The book presents a much fuller analysis of the variety of perceptual problems that John experienced, detailing not only his impaired object recognition but also his face processing, his processing of different visual features (colour, motion, depth), his ability to act on and negotiate his environment, and his reading and writing. A Case Study in Visual Agnosia Revisited will be a key reference for those concerned with understanding how vision is implemented in the brain. It will be suitable for both undergraduate students taking courses in cognitive psychology and neuropsychology, and also researchers in the cognitive neuroscience of vision. The presentation of John’s case, and the human aspects of the disorder, will also be of great interest to a general audience of lay people interested in perception.

The case study of John has provided a unique insight into the nature of visual agnosia and more broadly into the underlying processes which support human vision. After suffering a stroke, John had problems in recognizing common objects, faces, seeing colours, reading and finding his way around his environment. A Reader in Visual Agnosia brings together the primary scientific papers describing the detailed investigations for each visual problem which the authors carried out with John, known as patient HJA. This work was summarised initially in To See But Not To See (1987), and 26 years later in A Case Study in Visual Agnosia Revisited (2013). The chapters are divided into 6 parts corresponding to the key areas of investigation: Integrative visual agnosia Perception of global form Face perception Colour perception Word recognition Changes over time Each part contains a short introduction, written by the two leading researchers who worked with John, which highlights the relations between the papers and demonstrates the pathway of the case analysis. The book will be invaluable to students and researchers in visual cognition, cognitive neuropsychology and vision neuroscience.

Brain damage may sometimes cause specific impairments in human behaviour. One rare impairment is the failure to recognize everyday objects by sight, a problem which is termed "visual agnosia". In this book, the authors discuss the case of a patient,

One important means to understanding normal cognitive functions is the study of the breakdown of these functions following brain damage. This book provides reviews of major case studies dealing with the breakdown of visual perception and recognition, including the 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. The cases are discussed in the light of studies that have followed since, and the chapters provide a context in which the contributions of the case studies can be evaluated.

The cognitive neuroscience of human vision draws on two kinds of evidence: functional imaging of normal subjects and the study of neurological patients with visual disorders. Martha Farah's landmark 1990 book Visual Agnosia presented the first comprehensive analysis of disorders of visual recognition within the framework of cognitive neuroscience, and remains the authoritative work on the subject. This long-awaited second edition provides a reorganized and updated review of the visual agnosias, incorporating the latest research on patients with insights from the functional neuroimaging literature. Visual agnosia refers to a multitude of different disorders and syndromes, fascinating in their own right and valuable for what they can tell us about normal human vision. 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 autonomically. 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. The second edition extends the range of disorders covered to include disorders of topographic recognition, and both general and selective disorders of semantic memory, as well as expanded coverage of face recognition impairments. Also included are a discussion of the complementary roles of imaging and patient-based research in cognitive neuroscience, and a final integrative chapter presenting the "big picture" of object recognition as illuminated by agnosia research.

At the age of twenty eight Gary was assaulted by a gang with baseball bats and a hammer, resulting in several skull fractures and severe brain damage. For nineteen months he had little awareness of his surroundings before he started to show some recovery. This inspirational book documents his exceptional journey. The book presents a series of interviews with Gary, his mother Wendie, who never gave up, the medical team who initially treated him, and the therapists who worked with him over a period of three years. Through their testimony we learn about the devastating effects which can follow a serious assault to the head, and the long process of recovery over several years. With specialist rehabilitation and continuing family support Gary has exceeded expectations and, apart from some minor physical problems, he is now a normal young man. Surviving Brain Damage after Assault shows that, contrary to popular belief, considerable gains can be made by people who have experienced a long period of reduced consciousness. The book will be of great value to all professionals working in rehabilitation - psychologists, speech and language therapists, occupational therapists, social workers and rehabilitation doctors, and to people who have sustained a brain injury and their families.
