Book Synopsis Visual Psychophysics by : Zhong-Lin Lu
Download or read book Visual Psychophysics written by Zhong-Lin Lu and published by MIT Press. This book was released on 2013-10-11 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive treatment of the skills and techniques needed for visual psychophysics, from basic tools to sophisticated data analysis. Vision is one of the most active areas in biomedical research, and visual psychophysical techniques are a foundational methodology for this research enterprise. Visual psychophysics, which studies the relationship between the physical world and human behavior, is a classical field of study that has widespread applications in modern vision science. Bridging the gap between theory and practice, this textbook provides a comprehensive treatment of visual psychophysics, teaching not only basic techniques but also sophisticated data analysis methodologies and theoretical approaches. It begins with practical information about setting up a vision lab and goes on to discuss the creation, manipulation, and display of visual images; timing and integration of displays with measurements of brain activities and other relevant techniques; experimental designs; estimation of behavioral functions; and examples of psychophysics in applied and clinical settings. The book's treatment of experimental designs presents the most commonly used psychophysical paradigms, theory-driven psychophysical experiments, and the analysis of these procedures in a signal-detection theory framework. The book discusses the theoretical underpinnings of data analysis and scientific interpretation, presenting data analysis techniques that include model fitting, model comparison, and a general framework for optimized adaptive testing methods. It includes many sample programs in Matlab with functions from Psychtoolbox, a free toolbox for real-time experimental control. Once students and researchers have mastered the material in this book, they will have the skills to apply visual psychophysics to cutting-edge vision science.

Book Synopsis Visual Psychophysics by : Dorothea Jameson
Download or read book Visual Psychophysics written by Dorothea Jameson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on Visual Psychophysics documents the current status of research aimed toward understanding the intricacies of the visual mechanism and its laws of operation in intact human perceivers. As can be seen from the list of contributors, the problems of vision engage the interest and experimental ingenuity of investi gators from a variety of disciplines. Thus we find authors affiliated with depart ments of biology, medical and physiological physics, ophthalmology, physics, physiology and anatomy, psychology, laboratories of neurophysiology, medical clinics, schools of optometry, visual and othcr types of research institutes. A continuing interplay between psychophysical studies and physiological work is everywhere evident. As more information about the physiological basis of vision accumulates, and new studies and analyses of receptor photochemistry and the neurophysiology of retina and brain appear, psychophysical studies of the intact organism become more sharply focused, sometimes more complex, and often more specialized. Technological advances have increased the variety and precision of the stimulus controls, and advances in measurement techniques have reopened old problems and stimulated the investigation of new ones. In some cases, new concepts are being drawn in to help further our under standing of the laws by which the visual mechanism operates; in other cases, ideas enunciated long ago have been reevaluated, developed more fully, and reified in terms of converging evidence from both psychophysical experiments and unit recordings from visual cells.

Book Synopsis Visual Psychophysics and Physiology by : John Armington
Download or read book Visual Psychophysics and Physiology written by John Armington and published by Elsevier. This book was released on 2012-12-02 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual Psychophysics and Physiology: A Volume Dedicated to Lorrin Riggs illustrates a particular approach to the study of vision. It also celebrates Lorrin Riggs' retirement from formal teaching duties. During his teaching career Riggs advised and directed about fifty doctoral and postdoctoral students, many of whom wrote the chapters that make up this volume. The book is organized into six parts. Part 1 explains the approach to the study of vision, thus providing the philosophical theme for the chapters that follow. Part 2 on physiological mechanisms presents examples of comparative and physiological investigations. Part 3 on sensitivity and adaptation examines new research that bears directly upon the classical problems of visual psychophysics. Here, there is an initial concern with measurement, visual sensitivity, scaling, and adaptation. Part 4 discusses research on color vision while Part 5 on acuity, contrast, and movement considers some of the factors that contribute to these perceptions. Part 6 deals with applications of visual science to other disciplines. Specific examples are given that link visual research with ophthalmology, child development, and the investigation of cognitive variables such as meaning, activation, and so forth.

Book Synopsis Psychophysics Beyond Sensation by : Christian Kaernbach
Download or read book Psychophysics Beyond Sensation written by Christian Kaernbach and published by Psychology Press. This book was released on 2004-05-20 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a series of studies that expand laws, invariants, and principles of psychophysics beyond its classical domain of sensation. This book's goal is to demonstrate the extent of the domain of psychophysics, ranging from sensory processes, through sensory memory and short-term memory issues, to the interaction between sensation and action. The dynamics and timing of human performance are a further important issue within this extended framework of psychophysics: Given the similarity of the various cortical areas in terms of their neuroanatomical structure, it is an important question whether this similarity is paralleled by a similarity of processes. These issues are addressed by the contributions in the present volume using state-of-the-art research methods in behavioral research, psychophysiology, and mathematical modeling. The book is divided into four sections. Part I presents contributions concerning the classical domain of psychophysical judgment. The next two parts are concerned with elementary and higher-order processes and the concluding section deals with psychophysical models. The sections are introduced by guest editorials contributed by independent authors. These editorials present the authors' personals view on the respective section, providing an integrated account of the various contributions or highlighting their focus of interest among them. While also voicing their own and sometimes different point of view, they contribute to the process of discussion that makes science so exciting. This volume should be of great interest to advanced students in neuroscience, cognitive science, psychology, neuropsychology, and related areas who seek to evaluate the range and power of psychological work today. Established scientists in those fields will also appreciate the variety of issues addressed within the same methodological framework and their multiple interconnections and stimulating "cross-talk."

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 Psychology Press. This book was released on 2014-06-27 with total page 1090 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 Visual Dysfunction in Diabetes by : Joyce Tombran-Tink
Download or read book Visual Dysfunction in Diabetes written by Joyce Tombran-Tink and published by Springer Science & Business Media. This book was released on 2011-12-15 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: An exciting contribution to the field, Visual Dysfunction in Diabetes: The Science of Patient Impairment and Improvement is designed with two overriding objectives: to help readers understand the impact of vision impairment in people living daily with diabetes rather than considering diabetic retinopathy solely as a medical problem, and to explore what we know and don't know about the ways diabetes affect the eye. With the plethora of new information being generated, there are still a series of fundamental questions that must be addressed if effective treatments for diabetic retinopathy are to be found and applied. Developed by a renowned group of authorities, Visual Dysfunction in Diabetes: The Science of Patient Impairment and Improvement offers responses and context for a range of questions, such as: do metabolic factors beyond glucose contribute to vision-threatening diabetic retinopathy? If so, how do these lead to vision impairment? Is diabetic retinopathy a response to systemic metabolic abnormalities or are there unique ocular problems related to insulin resistance? What is the relationship between the neural, vascular, and inflammatory abnormalities in diabetic retinopathy? Do they represent a pathological cascade induced sequentially or simultaneous responses to one or more metabolic perturbations? The authors note that if we do not address these types of questions, it is possible that the long process of developing new therapeutics will target only one arm of the pathology and leave the retina open to damaging consequences of the others. State-of-the-art, comprehensive, and an invaluable addition the research and clinical literature, Visual Dysfunction in Diabetes: The Science of Patient Impairment and Improvement offers guidance and a significant step toward new scientific approaches that can lessen the devastating vision impairment associated with diabetes.
