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.

This book was released on 2009-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saccades are fast, ballistic eye movements. Irrespective of the substantial differences between pre- and post-saccadic retinal images, visual perception across saccades appears as being continuous and stable. Active, compensational mechanisms are necessary to construct this spatial and temporal stability. Under laboratory conditions the limits of these compensatory mechanisms are unveiled. In the temporal vicinity of saccades, characteristic misperceptions can be demonstrated. In this study, psychophysical experiments with human participants were conducted, addressing different aspects of temporal and spatial, trans-saccadic stability. We investigated the peri-saccadic perception of time, perceptual consequences of saccadic adaptation, the peri-saccadic representation of object features, and the impact of emotionally relevant saccade targets.

Available in PDF, EPUB and Kindle. Book excerpt: The distinguished contributors to this volume have been set the problem of describing how we know where to move our eyes. There is a great deal of current interest in the use of eye movement recordings to investigate various mental processes. The common theme is that variations in eye movements indicate variations in the processing of what is being perceived, whether in reading, driving or scene perception. However, a number of problems of interpretation are now emerging, and this edited volume sets out to address these problems. The book investigates controversies concerning the variations in eye movements associated with reading ability, concerning the extent to which text is used by the guidance mechanism while reading, concerning the relationship between eye movements and the control of other body movements, the relationship between what is inspected and what is perceived, and concerning the role of visual control attention in the acquisition of complex perceptual-motor skills, in addition to the nature of the guidance mechanism itself. The origins of the volume are in discussions held at a meeting of the European Society for Cognitive Psychology (ESCOP) that was held in Wurzburg in September 1996. The discussions concerned the landing effect in reading, an effect, that if substantiated, would provide evidence of the use of parafoveal information in eye guidance, and these discussions were explored in more detail at a small meeting in Chamonix, in February 1997. Many of the contributors to this volume were present at the meeting, but the arguments were not resolved in Chamonix either. Other leaders in the field were invited to contribute to the discussion, and this volume is the product. The argument remains unresolved, but the problem is certainly clearer.

This book was released on 1990 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to deal exclusively with oculomotor performance in a series that, up to this point, has been devoted largely to reviews of research on oculomotor anatomy and physiology. The publication of this volume signifies the recognition of the fact that a genuine understanding of eye movement will not come about through the study of neurons alone. We need to know about the capacity to make different kinds of eye movement, and about how such oculomotor capacity is used to accomplish different sorts of visual and cognitive tasks, i.e. how the eye can move and why it moves in particular ways. Research on respective topics was critically evaluated by the contributing authors, resulting in a controversial and up-to-date appraisal of this subject.

Available in PDF, EPUB and Kindle. Book excerpt: "Primates have evolved to make high velocity, ballistic eye movements called saccades approximately three to five times per second in order to orient the high resolution part of their retina, or fovea, towards objects of interest. While saccades are generally adaptive in most situations, they also present the brain with certain challenges in order maintain a stable perception of the world. With every movement of the visual axis involving the eyes alone or through a combined eye-head gaze shift, the retina is presented with a rapidly changing view of the world. Most observers are not aware of the actual flow of incoming retinal information during a saccade, and instead perceive the world as being stable from one gaze movement to the next. How the brain accomplishes this stability has been referred to as the problem of 'trans-saccadic' perceptual stability. While this problem been pondered for more than a century by philosophers, psychologists, and neuroscientists, there is still no consensus on the precise mechanism by which visual stability is achieved. One way to approach the problem of perceptual stability is to study the way in which visual perception changes around the time of saccades. It is well known that objects briefly presented around the time of saccadic eye movements are not perceived at their veridical location, a phenomenon called perisaccadic mislocalization. Most observers make errors of two types that are predictable and systematic: a translational shift in the direction of the saccade, and compression towards the target location. This later effect, the compression of visual space towards the saccade target, is the primary phenomenon through which this thesis sought to understand the mechanisms responsible for visual stability across saccades. To this end, a series of psychophysical experiments were conducted to explore which signals may be involved in computing where an object was in space around the time of a saccade. In the fist paper, we described a biological framework in which an oculomotor signal encoding the gaze command interacts with a visual signal encoding afferent information. The outcome of this interaction was related to the perceived position of the object presented around the time of the saccade, and this formulation was able to capture both our results in addition to data from outside our laboratory. After successfully modelling the compression effect within a plausible biological framework, the next paper focused on elucidating the nature of the oculomotor signal. We accomplished this by testing observers in a variety of conditions aimed to disambiguate whether the signal was encoding the eye movement alone or the eye-head gaze shift, and found that compression was indeed linked to the eye-head gaze shift. Moreover, the experiments performed allowed us to further describe the parameters involved in modulating the compression effect. With our understanding of the compression effect and the likely biological signals involved, we then used this model to gain an enhanced understanding of how perisaccadic visual perception may be altered in patients with schizophrenia. The final paper examines the postulate that patients with schizophrenia may have an altered corollary discharge signal in the visual pathway for saccadic eye movements. With this study we were able to show that these patients do in fact exhibit qualitative differences in mislocalization compared to controls, and that these are attributable to a noisy corollary discharge that encodes the eye's position in space. This thesis comprises a systematic overview of what signals are involved in maintaining perceptual stability across saccadic eye and head movements. We have been able to investigate these signals through a combination of psychophysical studies and computational modeling. Finally, we used these paradigms to understand how these signaling mechanisms are altered in patients with schizophrenia. " --

Available in PDF, EPUB and Kindle. Book excerpt: When we try to remember whether we left a window open or closed, do we actually see the window in our mind? If we do, does this mental image play a role in how we think? For almost a century, scientists have debated whether mental images play a functional role in cognition. In The Case for Mental Imagery, Stephen Kosslyn, William Thompson, and Giorgio Ganis present a complete and unified argument that mental images do depict information, and that these depictions do play a functional role in human cognition. They outline a specific theory of how depictive representations are used in information processing, and show how these representations arise from neural processes. To support this theory, they seamlessly weave together conceptual analyses and the many varied empirical findings from cognitive psychology and neuroscience. In doing so, they present the conceptual grounds for positing this type of internal representation and summarize and refute arguments to the contrary. Their argument also serves as a historical review of the imagery debate from its earliest inception to its most recent phases, and provides ample evidence that significant progress has been made in our understanding of mental imagery. In illustrating how scientists think about one of the most difficult problems in psychology and neuroscience, this book goes beyond the debate to explore the nature of cognition and to draw out implications for the study of consciousness. Student and professional researchers in vision science, cognitive psychology, philosophy, and neuroscience will find The Case for Mental Imagery to be an invaluable resource for understanding not only the imagery debate, but also and more broadly, the nature of thought, and how theory and research shape the evolution of scientific debates.

Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, there has been an explosion of eye movement research in cognitive science and neuroscience. This has been due to the availability of 'off the shelf' eye trackers, along with software to allow the easy acquisition and analysis of eye movement data. Accompanying this has been a realisation that eye movement data can be informative about many different aspects of perceptual and cognitive processing. Eye movements have been used to examine the visual and cognitive processes underpinning a much broader range of human activities, including, language production, dialogue, human computer interaction, driving behaviour, sporting performance, and emotional states. Finally, in the past thirty years, there have been real advances in our understanding of the neural processes that underpin eye movement behaviour. The Oxford Handbook of Eye Movements provides the first comprehensive review of the entire field of eye movement research. In over fifty chapters, it reviews the developments that have so far taken place, the areas actively being researched, and looks at how the field is likely to devlop in the coming years. The first section considers historical and background material, before moving onto section 2 on the neural basis of eye movements. The third and fourth sections looks at visual cognition and eye movements and eye movement pathology and development. The final sections consider eye movements and reading and language processing and eye movements. Bringing together cutting edge research from and international team of leading psychologists, neuroscientists, and vision researchers, this book is the definitive reference work in this field.
