Available in PDF, EPUB and Kindle. Book excerpt: Psychophysical Analysis of Visual Space focuses on the use of psychophysics in the analysis of visual space, with emphasis on space perception and physiological optics. Topics covered include null-size judgment, ratio-size judgment, frontal-size judgment, and distance judgment, as well as selected physiological correlates of size and distance judgments. A theoretical analysis of model reduction is also presented. This volume consists of 11 chapters and opens with an overview of basic definitions and evidence in support of the constancy hypothesis. A psychophysical approach to the problems of visual space is described. The reader is then introduced to null-size judgment, ratio-size judgment, frontal-size judgment, and distance judgment, with emphasis on the importance of the retina as a reference for spatial judgments and how size judgments of targets at different distances can be related to judgments of targets at a constant distance. Some of the important relationships between ocular physiology and size-distance judgments are also examined, paying particular attention to size and distance judgments which relate to the variables of convergence, accommodation, angle-of-regard, and binocular disparity. The remaining chapters look at two stimulus correlates of distance judgments: frontal size and longitudinal size. This book will be of interest to physiologists, physicists, and experimental psychologists.

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.

Available in PDF, EPUB and Kindle. Book excerpt: When most people think of space, they think of physical space. However, visual space concerns space as consciously experienced, and it is studied through subjective measures, such as asking people to use numbers to estimate perceived distances, areas, angles, or volumes. This book explores the mismatch between perception and physical reality, and describes the many factors that influence the perception of space including the meaning assigned to geometric concepts like distance, the judgment methods used to report the experience, the presence or absence of cues to depth, and the orientation of a stimulus with respect to point of view. The main theme of the text is that no single geometry describes visual space, but that the geometry of visual space depends upon the stimulus conditions and mental shifts in the subjective meaning of size and distance. In addition, The Geometries of Visual Space: *contains philosophical, mathematical, and psychophysical background material; *looks at synthetic approaches to space perception including work on hyperbolic, spherical, and Euclidean geometries; *presents a meta-analysis of studies that ask observers to directly estimate size, distance, area, angle, and volume; *looks at the size constancy literature in which observers are asked to adjust a comparison stimulus to match a variety of standards at different distances away; *discusses research that takes a multi-dimensional approach toward studying visual space; and *discusses how spatial experience is influenced by memory. While this book is primarily intended for scholars in perception, mathematical psychology, and psychophysics, it will also be accessible to a wider audience since it is written at a readable level. It will make a good graduate-level textbook on space perception.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The visual system must extract from the light that falls on the retina meaningful information about what is where in our environment. At an early stage it analyzes the incoming sensory data along many dimensions of pattern vision, e.g. spatial frequency, orientation, velocity, eye-of-origin. Visual Pattern Analyzers provides a definitive account of current knowledge about this stage of visual processing. Nowhere else can such a comprehensive summarty of the lower level pattern analyzers be found. The book's emphasis is on psychophysical experiments measuring the detection and identification of near-threshold patterns -- and the mathematical models, such as multidimensional signal-detection theory, used to draw inferences from such experimental results -- but neurophysiological evidence is presented and compared critically to the psychophysical evidence. Introductory material on psychophysical methods, signal detection theory, and the mathematics of Fourier analysis is given in order to make the book more accessible to all who are interested in the lower or higher levels of visual perception. This volume will be of great value to researchers and graduate students in the fields of vision and perception. Within the scientific community there is wide interest in the visual system, and the book will be of use to investigators in many fields, including psychophysics, neuroscience, ophthalmology and optics, computer science, and cognitive and experimental psychology.

Available in PDF, EPUB and Kindle. Book excerpt: This volume starts from an interdisciplinary expertise of the contributors, and chooses to work on the very origins of conscious qualitative states in perception. The leading research paradigm can be synthesized in ‘phenomenology to neurons to stimuli, and backwards’, since as a starting point it has taken the phenomenal appearances in the visual field. Specifically, the leading theme of the volume is the co-presence and interaction of diverse types of spaces in vision, like the optical space of psychophysics and of neural elaboration, the qualitative space of phenomenal appearances, and its relation with the pictorial space of art. The contributors to the volume agree in arguing that those spaces follow different rules of organization, whose specific singularity and reciprocal dependence have to be individuated, as a preliminary step to understand the architecture of the conscious awareness of our environment and to conceive its potential implementation in constructing any kind of embodied intentional agents.

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.
