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 chapters in this new book span the range of reading processes
from early visual analysis to semantic influences on word
identification, thus providing a state-of-the-art summary of
current work and offering important contributions to prospective
reading research.
Originally published in 1987, this book, attempted to bring together work by researchers concerned with the functional and neurological mechanisms underlying visual object processing, and the ways in which such mechanisms can be neurologically impaired. The editors termed it a 'Cognitive Neuropsychological' approach, because they believed it tried to relate evidence from neurological impairments of visual object processing to models of normal performance in a new and important way. Two broad aims are apparent. One is to test models of normal performance by evaluating how well the models account for the patterns of impairment and preservation of abilities that can occur following brain damage. The other is to use models of normal performance to further their understanding of acquired disorders of visual object processing. These aims distinguish the approach from neuropsychological work whose primary aim is to relate acquired deficits to the sites of damage, and from work in the field of cognitive psychology which attempts only to develop models of normal performance.
In the World Library of Psychologists series, international experts themselves present career-long collections of what they judge to be their finest pieces - extracts from books, key articles, salient research findings, and their major practical theoretical contributions. Glyn Humphreys is an internationally renowned cognitive neuropsychologist with research interests covering object recognition and its disorders, visual word recognition, object and spatial attention, the effects of action on cognition, and social cognition. Within the field of Psychology he has won a number of prestigious awards, including the Spearman Medal, the President's Award of the British Psychological Society, and the Donald Broadbent Prize from the European Society for Cognitive Psychology. This collection reflects the different directions in his work and approaches which have been adopted. It will enable the reader to trace key developments in cognitive neuropsychology in a period of rapid change over the last thirty years. A newly written introduction contextualises the selection in relation to changes in the field during this time. Attention, Perception and Action will be invaluable reading for students and researchers in visual cognition, cognitive neuropsychology and vision neuroscience.

BORB provides a set of standardised procedures for assessing
neuropsychological disorders of visual object recognition, based on
tests developed in the cognitive neuropsychological literature. The
tests are introduced in terms of cognitive neuropsychological
analyses of object recognition, and guidance is given concerning
test use and interpretation.
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.
Brain damage may sometimes cause remarkably specific impairments in human behaviour. One very rare and specific 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, John, who suffered from visual agnosia after having a stroke. John also had difficulty recognizing faces or his immediate environment. The book considers John's case from the point of view of current psychological theories of visual recognition, and from a review of other documented cases. It goes on to consider the implications of John's problems for understanding how we might normally recognize objects, drawing on investigations of his impairments. The book also includes chapters contributed by John and his wife.
This volume will contain papers from the 5th Neural Computation and Psychology Workshop, University of Birmingham, UK, 8-10 September 1998. The theme of the workshop is Connectionist Models in Cognitive Neuroscience, a topic which covers many important issues ranging from modelling physiological structure, to cognitive function and its disorders in neuropsychological and psychiatric cases. The workshop is intended to bring together researchers from such diverse disciplines as artificial intelligence, applied mathematics, cognitive science, computer science, neurobiology, philosophy and psychology, to discuss their work on the connectionist modelling of psychology. The papers will provide a state of the art summary of ongoing research in this exciting and fast-moving field. As such this volume will provide a valuable contribution to the Perspectives in Neural Computing series.
