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."

Download or read book The Processes of Visual Perception written by William R. Utall and published by . This book was released on 1979 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the contents of a book entitled The Processes of Visual Perception written during the course of this contract. The book presents a classification system of visual processes that organizes and arranges the extensive data base of perceptual science. The taxonomy consists of 6 levels: Level 0, Preneural Transformations; Level 1, Receptor Transformations; Level 2, Neural Network Transformations; Level 3, Figural Organization Processes; Level 4, Multidimensional Interactions; and Level 5 Image Manipulation. (Level 5 is not discussed in this book. It will be the topic of the next book in the series of which this present one is the third volume.) This progress report presents a brief summary of each of the chapters in the book as well as the entire last chapter. This final epilog, entitled 'Emerging Principles of Visual Perception' was the target towards which this entire research project was aimed. At the outset of the book, it was asserted that the major contribution it could make would be the statement of current thinking in the field of perceptual science. This list of principles, as well as the taxonomy itself, is a synthetic and integrative metatheory of perceptual processing as our science sees it in the last third of the twentieth century.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In the mid-sixties, John Robson and Christina Enroth-Cugell, without realizing what they were doing, set off a virtual revolution in the study of the visual system. They were trying to apply the methods of linear systems analysis (which were already being used to describe the optics of the eye and the psychophysical performance of the human visual system) to the properties of retinal ganglion cells in the cat. Their idea was to stimulate the retina with patterns of stripes and to look at the way that the signals from the center and the antagonistic surround of the respective field of each ganglion cell (first described by Stephen Kuffier) interact to generate the cell's responses. Many of the ganglion cells behaved themselves very nicely and John and Christina got into the habit (they now say) of calling them I (interesting) cells. However. to their annoyance, the majority of neurons they recorded had nasty, nonlinear properties that couldn't be predicted on the basis of simple summ4tion of light within the center and the surround. These uncoop erative ganglion cells, which Enroth-Cugell and Robson at first called D (dull) cells, produced transient bursts of impulses every time the distribution of light falling on the receptive field was changed, even if the total light flux was unaltered.
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.

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.
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 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.

Download or read book What can simple brains teach us about how vision works written by Davide Zoccolan and published by Frontiers Media SA. This book was released on 2015-11-18 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision is the process of extracting behaviorally-relevant information from patterns of light that fall on retina as the eyes sample the outside world. Traditionally, nonhuman primates (macaque monkeys, in particular) have been viewed by many as the animal model-of-choice for investigating the neuronal substrates of visual processing, not only because their visual systems closely mirror our own, but also because it is often assumed that “simpler” brains lack advanced visual processing machinery. However, this narrow view of visual neuroscience ignores the fact that vision is widely distributed throughout the animal kingdom, enabling a wide repertoire of complex behaviors in species from insects to birds, fish, and mammals. Recent years have seen a resurgence of interest in alternative animal models for vision research, especially rodents. This resurgence is partly due to the availability of increasingly powerful experimental approaches (e.g., optogenetics and two-photon imaging) that are challenging to apply to their full potential in primates. Meanwhile, even more phylogenetically distant species such as birds, fish, and insects have long been workhorse animal models for gaining insight into the core computations underlying visual processing. In many cases, these animal models are valuable precisely because their visual systems are simpler than the primate visual system. Simpler systems are often easier to understand, and studying a diversity of neuronal systems that achieve similar functions can focus attention on those computational principles that are universal and essential. This Research Topic provides a survey of the state of the art in the use of animal models of visual functions that are alternative to macaques. It includes original research, methods articles, reviews, and opinions that exploit a variety of animal models (including rodents, birds, fishes and insects, as well as small New World monkey, the marmoset) to investigate visual function. The experimental approaches covered by these studies range from psychophysics and electrophysiology to histology and genetics, testifying to the richness and depth of visual neuroscience in non-macaque species.
