Book Description
Describes a range of exciting new approaches to neuropsychological investigation and provides a broad overview of visual neuropsychology. The book starts by examining the neural basis of perception - presenting important new research using single-unit recordings. It then considers disturbances of visual perception such a agnosia, neglect, blindsight, and achromatopsia, describing what we now know about recovery and rehabilitation from cerebral visual disorders. Throughout, the book refers to new and adapted techniques for measuring brain activity, including multi-unit sum potential recording, fMRI, and transranial magnetic-stimulation. With contributions from leading scientists in the vision sciences, it provides a state-of-the-art review of the topic.

Book Description
This book provides a state-of-the-art review of high-level vision and the brain. Topics covered include object representation and recognition, category-specific visual knowledge, perceptual processes in reading, top-down processes in vision -- including attention and mental imagery -- and the relations between vision and conscious awareness. Each chapter includes a tutorial overview emphasizing the current state of knowledge and outstanding theoretical issues in the authors' area of research, along with a more in-depth report of an illustrative research project in the same area. The editors and contributors to this volume are among the most respected figures in the field of neuropsychology and perception, making the work presented here a standard-setting text and reference in that area.

Book Description
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.

Book Description
This title focuses on vision as an active process, rather than a passive activity and provides an integrated account of seeing and looking. The authors give a thorough description of basic details of the visual and oculomotor systems necessary to understand active vision.

Book Description
Originally published in 1989, this sourcebook for anatomic studies in the neuropsychology of visual perception contains chapters on disorders of visual agnosias, impaired object perception and spatial neglect, and abnormal visual imagery. The neurological basis of visual perception and the disorders that result from brain damage are discussed. At the time the chapters in this volume constituted a state of the art survey in this area and provided data that were essential for the development of models of normal image and object formation.

Book Description
An investigation of the effects of blindness and other types of visual deficit on cognitive abilities. Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain—as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.

Book Description
Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.

Book Description
Vision allows us to do many things. It enables us to perceive a world composed of meaningful objects and events. It enables us to track those events as they take place in front of our eyes. It enables us to read. It provides accurate spatial information for actions such as reaching for or avoiding objects. It provides colour and texture that can help us to separate objects from their background, and so forth. This book is concerned with understanding the processes that allow us to carry out these various visually'driven behaviours. In the past ten years our understanding of visual processing has undergone a rapid change, primarily fostered by the convergence of computational, experimental and neuropsychological work on the topic. Visual Cognition provides the first major attempt to cover all aspects of this work within a single text. It provides a state'of'the'art summary of research on visual information processing, relevant to advanced undergraduates, postgraduates and research workers. It covers: seeing static forms, object recognition, dynamic vision (motion perception and visual masking), visual attention, visual memory, visual aspects of reading. For each topic, the relevant computational, experimental and neuropsychological work is integrated to provide a broader coverage than that of other texts.
