Vision Perception And Cognition

This book is a text that addresses clinical reasoning and decision making for the entire evaluation and treatment process of the adult with acquired brain injury. Provided are theoretical information, guidelines for both static and dynamic assessment, information on specific standardized evaluations, guidelines for adaptive and restorative treatment based on described theoretical and evidence-based information, and information on environmental impact of client performance. The author addresses visual, perceptual, and cognitive evaluation and treatment, providing structure, clarity, and content suitable for both students and experienced clinicians. Updated and expanded to reflect current practice and relevant research, the fourth edition is a resource that takes the reader from theory to practice in a practical and detailed way. It contains numerous tables, figures, and extensive references presented throughout the text. Also included is an on-line instructor's manual for additional classroom learning objectives and activities.

This book explores a central question in the study of depth perception - 'does the visual system rely upon objective knowledge and subjective meaning to specify visual depth?' Linton advances an alternative interpretation to the generally accepted affirmative answer, according to which many of the apparent contributions of knowledge and meaning to depth perception are better understood as contributions to our post-perceptual cognition of depth. In order to defend this position a new account of visual cognition is required, as well as a better understanding of the optical and physiological cues to depth. This book will appeal to students and researchers in psychology, vision science, and philosophy, as well as technologists and content creators working in virtual and augmented reality.

An argument that there are perceptual mechanisms that retrieve information in cognitively and conceptually unmediated ways and that this sheds light on various philosophical issues. In Cognition and Perception, Athanassios Raftopoulos discusses the cognitive penetrability of perception and claims that there is a part of visual processes (which he calls “perception”) that results in representational states with nonconceptual content; that is, a part that retrieves information from visual scenes in conceptually unmediated, “bottom-up,” theory-neutral ways. Raftopoulos applies this insight to problems in philosophy of science, philosophy of mind, and epistemology, and examines how we access the external world through our perception as well as what we can know of that world. To show that there is a theory-neutral part of existence, Raftopoulos turns to cognitive science and argues that there is substantial scientific evidence. He then claims that perception induces representational states with nonconceptual content and examines the nature of the nonconceptual content. The nonconceptual information retrieved, he argues, does not allow the identification or recognition of an object but only its individuation as a discrete persistent object with certain spatiotemporal properties and other features. Object individuation, however, suffices to determine the referents of perceptual demonstratives. Raftopoulos defends his account in the context of current discussions on the issue of the theory-ladenness of perception (namely the Fodor-Churchland debate), and then discusses the repercussions of his thesis for problems in the philosophy of science. Finally, Raftopoulos claims that there is a minimal form of realism that is defensible. This minimal realism holds that objects, their spatiotemporal properties, and such features as shape, orientation, and motion are real, mind-independent properties in the world.

Joan Vickers presents evidence on gaze control within visual perception and action in sport as well as the science underlying decision training.

Vision allows us to do many things. It enables us to perceive a world composed of meaningful objects and events. It enables us to track those events as they take place in front of our eyes. It enables us to read. It provides accurate spatial information for actions such as reaching for or avoiding objects. It provides colour and texture that can help us to separate objects from their background, and so forth. This book is concerned with understanding the processes that allow us to carry out these various visually driven behaviours. In the past ten years our understanding of visual processing has undergone a rapid change, primarily fostered by the convergence of computational, experimental and neuropsychological work on the topic. Visual Cognition provides the first major attempt to cover all aspects of this work within a single text. It provides a summary of research on visual information processing, relevant to advanced undergraduates, postgraduates and research workers. It covers: seeing static forms, object recognition, dynamic vision (motion perception and visual masking), visual attention, visual memory, visual aspects of reading. For each topic, the relevant computational, experimental and neuropsychological work is integrated to provide a broader coverage than that of other texts.
