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.

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 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.

Dyslexia affects about 10% of all children and is a potent cause of loss of self-confidence, personal and family misery, and waste of potential. Although the dominant view is that it is caused by specifically linguistic/phonological weakness, recent research within the field of neuroscience has shown that it is associated wtih visual processing problems as well. These discoveries have led to a resurgence in visual methods of treatment, which have shown promising results. 'Visual aspects of dyslexia' brings together cutting edge research from a range of disciplines - including neurology, neuroscience, and the vision sciences, to present the first comprehensive review of this recent research. It includes chapters from leading specialists which, in addition to reporting on the latest research, show how this knowledge is being successfully applied in the development of effective visual treatments for this common problem. Sections within the book cover the role of eye movements in reading, visual attention and reading, the neural bases of reading, and the relationship between visual stress and dyslexia. Making a valuable contribution in helping us develop a deeper understanding of dyslexia, this is an important book for those in the fields of psychology, neuroscience, and education.

This thoroughly updated and extended edition covers the various cerebral visual disorders acquired after brain injury, as well as the rehabilitation techniques used to treat them. These are described within a brain plasticity framework, using data from single and group case studies along with follow up observation data. This original, tailor-made approach also includes the recording of eye movements for assessing scanning performance in scene perception and reading. The book gives a brief synopsis of the historical background on the subject, alongside an outline of intervention designs and methodological difficulties in the field, and goes on to discuss the mechanisms and processes that provide the foundations for recovery of function and successful adaptation in visually impaired patients. The author concludes by analyzing the importance of the procedures and outcomes of treatments to the reduction of patients’ visual handicaps. The new edition also contains an appendix with recommendations on the case histories, diagnostics and treatments. It is ideal reading for students in clinical neuropsychology, as well as professionals in the fields of neurology, visual neuroscience and rehabilitation experts.
