Book Synopsis A Taxonomy of Visual Processes by : William R. Uttal
Download or read book A Taxonomy of Visual Processes written by William R. Uttal and published by . This book was released on 1981 with total page 1128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1981, this third volume deals with the empirical data base and the theories concerning visual perception the set of mental responses to photic stimulation of the eyes. As the book develops, the plan was to present a general taxonomy of visual processes and phenomena. It was hoped that such a general perspective would help to bring some order to the extensive, but largely unorganized, research literature dealing with our immediate perceptual responses to visual stimuli at the time. The specific goal of this work was to provide a classification system that integrates and systematizes the data base of perceptual psychology into a comprehensive intellectual scheme by means of an eclectic, multi-level "metatheory" invoking several different kinds of explanation."

Book Synopsis Emergent Techniques for Assessment of Visual Performance by : National Research Council
Download or read book Emergent Techniques for Assessment of Visual Performance written by National Research Council and published by National Academies Press. This book was released on 1985-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.

Book Synopsis The Visual (Un)Conscious and Its (Dis)Contents by : Bruno G. Breitmeyer
Download or read book The Visual (Un)Conscious and Its (Dis)Contents written by Bruno G. Breitmeyer and published by OUP Oxford. This book was released on 2014-06-12 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual control of our actions can be unconscious as well as conscious. For example, when a pedestrian steps onto a street and then suddenly steps back, to avoid being hit by an oncoming car, the pedestrian's visual system has been able to detect the car very rapidly. Since the registration of the approaching car in conscious vision could take a few hundreds of milliseconds - possibly too long to avoid being struck by it, the rapid injury-avoiding action has relied on the oncoming car being detected at unconscious levels in the visual system. So how, and at what level in the visual system is a stimulus processed unconsciously? This book explores unconscious and conscious vision, investigated using psychophysical and brain-recording methods. These methods allow microtemporal analyses of visual processing during the interval, ranging from a few 10s to a few 100s of milliseconds, between a stimulus's impinging on the retinae and its eliciting a behavioral response or a conscious percept. By tying these findings to well-known neuroanatomical and physiological substrates of vision, the book presents and discusses theoretical and empirical approaches to, and findings on, conscious and unconscious vision. In addition to presenting an in-depth, integrative review of recent and ongoing scientific and scholarly research, the book proposes several avenues for directing future research in these areas. It also provides a well articulated theoretical and a detailed empirical base that points to the special importance of the processing of surface properties of visual objects to their conscious vision. Aimed at scientists and scholars in visual cognition, visual neuroscience and, more broadly, cognitive science - including that part of the philosophical community that is currently occupied with the mind-brain problem, the book sheds new light on and advances experimental, philosophical, and scholarly research on visual consciousness.
Book Synopsis Discovering the Brain by : National Academy of Sciences
Download or read book Discovering the Brain written by National Academy of Sciences and published by National Academies Press. This book was released on 1992-01-01 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

Download or read book Visual Processing written by Roger Watt and published by Psychology Press. This book was released on 2022-03-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This highly original and interesting monograph puts forward ideas on visual processing and representation in the early stages of visual perception, and examines the computational requirements of the system and its psychological performance. Initially the author considers the computational theory of how the maximum amount of useful information about the scene can be registered from the variations in light intensity in the retinal image. He then goeson to address the question of just what it means to say that the visual system measures spatial aspects of the retinal image, and the consequences of the inevitable distortions that are introduced. He believes that the calculation of spatial position within a distorted metric is not trivial and requires dynamic processes with memory and control. Finally, Dr. Wan argues that the strength of the link between the low-level approaches of psychophysics and computational theory and high-level approaches of cognitive visual function lies in the logic of the arguments that indicate the computational need for control. This Essay will be of great interest to researchers in computer vision, perception, cognitive science and cognitive psychology.
Book Synopsis Microgenetic approach to the conscious mind by : Talis Bachmann
Download or read book Microgenetic approach to the conscious mind written by Talis Bachmann and published by John Benjamins Publishing. This book was released on 2000 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many secrets of nature have been discovered since we have a better understanding of microstructures, for example subatomic spheres in physics and genetic structures in biochemistry. This book is set to convey an overview of the history, methods, findings and theoretical accounts of microgenetic research in consciousness and experimental psychology. The reader will find information about how conscious percepts unfold within only a fraction of a second. In a sense, and according to the microgenetic hypothesis, our subjectively experienced perceptual image undergoes formation similar to the process of developing a photograph. Yet the time scale of the awareness-related perceptual development is much finer and therefore accessible only to observation armed with special experimental procedures that are exposed in this book. In addition, the author presents empirical findings and theoretical interpretations from his own lab. Professor Talis Bachmann has been active in microgenetic research on attention, perception and consciousness for more than 25 years. (Series B)
Book Synopsis Perception beyond Inference by : Liliana Albertazzi
Download or read book Perception beyond Inference written by Liliana Albertazzi and published by MIT Press. This book was released on 2023-09-19 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proposing a new paradigm for perceptual science that goes beyond standard information theory and digital computation. This book breaks with the conventional model of perception that views vision as a mere inference to an objective reality on the basis of "inverse optics." The authors offer the alternative view that perception is an expressive and awareness-generating process. Perception creates semantic information in such a way as to enable the observer to deal efficaciously with the chaotic and meaningless structure present at the physical boundary between the body and its surroundings. Vision is intentional by its very nature; visual qualities are essential and real, providing an aesthetic and meaningful interface to the structures of physics and the state of the brain. This view brings perception firmly in line with ethology and modern evolutionary biology and suggests new approaches in all disciplines that study, or require an understanding of, the ontology of mind. The book is the joint effort of a multidisciplinary group of authors. Topics covered include the relationships among stimuli, neuronal processes, and visual awareness. After considering the mind-dependent growing of information, the book treats time and dynamics; color, shape, and space; language and perception; perception, art, and design.
Book Synopsis On Seeing Forms by : William R. Uttal
Download or read book On Seeing Forms written by William R. Uttal and published by Psychology Press. This book was released on 2014-06-27 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1988, this is the final volume in the set. The original intent of the tetralogy was to review neural explanations of high level perceptual and cognitive processes. However, at this point, it became clear that there were few neural explanations of perceptual topics – a situation that still persists today. This book, therefore, used a different framework examining the role of detection, discrimination, and recognition at the behavioral level.
Book Synopsis Feedforward and Feedback Processes in Vision by : Hulusi Kafaligonul
Download or read book Feedforward and Feedback Processes in Vision written by Hulusi Kafaligonul and published by Frontiers Media SA. This book was released on 2015-07-10 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual system consists of hierarchically organized distinct anatomical areas functionally specialized for processing different aspects of a visual object (Felleman & Van Essen, 1991). These visual areas are interconnected through ascending feedforward projections, descending feedback projections, and projections from neural structures at the same hierarchical level (Lamme et al., 1998). Accumulating evidence from anatomical, functional and theoretical studies suggests that these three projections play fundamentally different roles in perception. However, their distinct functional roles in visual processing are still subject to debate (Lamme & Roelfsema, 2000). The focus of this Research Topic is the roles of feedforward and feedback projections in vision. Even though the notions of feedforward, feedback, and reentrant processing are widely accepted, it has been found difficult to distinguish their individual roles on the basis of a single criterion. We welcome empirical contributions, theoretical contributions and reviews that fit into any one (or a combination) of the following domains: 1) their functional roles for perception of specific features of a visual object 2) their contributions to the distinct modes of visual processing (e.g., pre-attentive vs. attentive, conscious vs. unconscious) 3) recent techniques/methodologies to identify distinct functional roles of feedforward and feedback projections and corresponding neural signatures. We believe that the current Research Topic will not only provide recent information about feedforward/feedback processes in vision but also contribute to the understanding fundamental principles of cortical processing in general.

Book Synopsis A Taxonomy for Texture Description and Identification by : A. Ravishankar Rao
Download or read book A Taxonomy for Texture Description and Identification written by A. Ravishankar Rao and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: A central issue in computer vision is the problem of signal to symbol transformation. In the case of texture, which is an important visual cue, this problem has hitherto received very little attention. This book presents a solution to the signal to symbol transformation problem for texture. The symbolic de- scription scheme consists of a novel taxonomy for textures, and is based on appropriate mathematical models for different kinds of texture. The taxonomy classifies textures into the broad classes of disordered, strongly ordered, weakly ordered and compositional. Disordered textures are described by statistical mea- sures, strongly ordered textures by the placement of primitives, and weakly ordered textures by an orientation field. Compositional textures are created from these three classes of texture by using certain rules of composition. The unifying theme of this book is to provide standardized symbolic descriptions that serve as a descriptive vocabulary for textures. The algorithms developed in the book have been applied to a wide variety of textured images arising in semiconductor wafer inspection, flow visualization and lumber processing. The taxonomy for texture can serve as a scheme for the identification and description of surface flaws and defects occurring in a wide range of practical applications.
Download or read book Visual Cognition written by Steven Pinker and published by MIT Press. This book was released on 1986-01-09 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: These essays tackle some of the central issues in visual cognition, presenting experimental techniques from cognitive psychology, new ways of modeling cognitive processes on computers from artificial intelligence, and new ways of studying brain organization from neuropsychology, to address such questions as: How do we recognize objects in front of us? How do we reason about objects when they are absent and only in memory? How do we conceptualize the three dimensions of space? Do different people do these things in different ways? And where are these abilities located in the brain? While this research, which appeared as a special issue of the journal Cognition, is at the cutting edge of cognitive science, it does not assume a highly technical background on the part of readers. The book begins with a tutorial introduction by the editor, making it suitable for specialists and nonspecialists alike.
Book Synopsis Visual Object Processing by : Glyn W. Humphreys
Download or read book Visual Object Processing written by Glyn W. Humphreys and published by Routledge. This book was released on 2017-03-27 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
