Download or read book A Case Study in Visual Agnosia Revisited written by Glyn Humphreys and published by Psychology Press. This book was released on 2013-10-15 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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. The tests assess low-level aspects of visual perception (using same-different matching of basic perceptual features, such as orientation, length, position and object size), intermediate visual processes (e.g., matching objects different in viewpoint), access to stored perceptual knowledge about objects (object decision), access to semantic knowledge (function and associative matches) and access to names from object (picture naming). BORB will serve as an invaluable companion test battery to the PALPA test of language ability.

Download or read book A Reader in Visual Agnosia written by Glyn Humphreys and published by Psychology Press. This book was released on 2016-01-13 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Visual Agnosia second edition written by Martha J. Farah and published by MIT Press. This book was released on 2004-04-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Man Who Mistook His Wife for a Hat written by Oliver Sacks and published by Vintage. This book was released on 2021-09-14 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his most extraordinary book, the bestselling author of Awakenings and "poet laureate of medicine” (The New York Times) recounts the case histories of patients inhabiting the compelling world of neurological disorders, from those who are no longer able to recognize common objects to those who gain extraordinary new skills. Featuring a new preface, Oliver Sacks’s The Man Who Mistook His Wife for a Hat tells the stories of individuals afflicted with perceptual and intellectual disorders: patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; whose limbs seem alien to them; who lack some skills yet are gifted with uncanny artistic or mathematical talents. In Dr. Sacks’s splendid and sympathetic telling, his patients are deeply human and his tales are studies of struggles against incredible adversity. A great healer, Sacks never loses sight of medicine’s ultimate responsibility: “the suffering, afflicted, fighting human subject.”

Download or read book Case Studies in the Neuropsychology of Vision written by Glyn W. Humphreys and published by Psychology Press. This book was released on 2013-04-15 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Mind s Eye written by Oliver Sacks and published by Vintage. This book was released on 2010-10-26 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Mind’s Eye, Oliver Sacks tells the stories of people who are able to navigate the world and communicate with others despite losing what many of us consider indispensable senses and abilities: the power of speech, the capacity to recognize faces, the sense of three-dimensional space, the ability to read, the sense of sight. For all of these people, the challenge is to adapt to a radically new way of being in the world. There is Lilian, a concert pianist who becomes unable to read music and is eventually unable even to recognize everyday objects, and Sue, a neurobiologist who has never seen in three dimensions, until she suddenly acquires stereoscopic vision in her fifties. There is Pat, who reinvents herself as a loving grandmother and active member of her community, despite the fact that she has aphasia and cannot utter a sentence, and Howard, a prolific novelist who must find a way to continue his life as a writer even after a stroke destroys his ability to read. And there is Dr. Sacks himself, who tells the story of his own eye cancer and the bizarre and disconcerting effects of losing vision to one side. Sacks explores some very strange paradoxes—people who can see perfectly well but cannot recognize their own children, and blind people who become hyper-visual or who navigate by “tongue vision.” He also considers more fundamental questions: How do we see? How do we think? How important is internal imagery—or vision, for that matter? Why is it that, although writing is only five thousand years old, humans have a universal, seemingly innate, potential for reading? The Mind’s Eye is a testament to the complexity of vision and the brain and to the power of creativity and adaptation. And it provides a whole new perspective on the power of language and communication, as we try to imagine what it is to see with another person’s eyes, or another person’s mind.
Download or read book The Neurobiology of Cognition and Behavior written by John Hart, Jr. and published by Oxford University Press. This book was released on 2016 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Neurobiology of Cognition and Behavior" is one of the initial textbooks of brain mapping in the field of cognitive neuroscience. This well-researched text by a leading expert in the field provides a foundational map of the human brain for cognition and behavior. This comprehensive map of essential human thinking and emotion is based on the explosion in the field of functional neuroimaging studies (fMRI, PET) in the normally functioning human brain. The approach of this text is to confirm the association of these brain regions by verifying that damage to the activated brain area results in a consistent deficit in the cognitive/behavioral operation under investigation. The approach used to form this view of mapping brain and cognition is based on cognitive neuroscience principles of defining dissociable, fine-grained cognitive units and associating these units with brain regions encoding for these units or aspects of the units from both functional imaging and lesion studies. These cognitive-brain relationships are incorporated into clinical syndromes to account for the behavior of these patients after a lesion occurs, with the added feature of presenting patient videos demonstrating the disrupted cognitive behaviors. This comprehensive textbook provides a framework of the basic architecture of cognition in the brain with this combination of activation and lesion study confirmation of the brain-behavior associations. This basic framework is useful for those students studying the interaction of cognitive science and neuroanatomy as well as being relevant to the experienced neuroscientist researcher or clinician.
