Sites of Vision


Book Description

The fourteen contributors to Sites of Vision explore the hypothesis that the nature of visual perception about which philosophers talk must be explicitly recognized as a discursive construction, indeed a historical construction, in philosophical discourse. In recent years scholars from many disciplines have become interested in the "construction" of the human senses--in how the human environment shapes both how and what we perceive. Taking a very different approach to the question of construction, Sites of Vision turns to language and explores the ways in which the rhetoric of philosophy has formed the nature of vision and how, in turn, the rhetoric of vision has helped to shape philosophical thought. The central role of vision in relation to philosophy is evident in the vocabulary of the discipline--in words such as "speculation," "observation," "insight," and "reflection"; in metaphors such as "mirroring," "perspective," and "point of view"; and in methodological concepts such as "reflective detachment" and "representation." Because the history of vision is so pervasively reflected in the history of philosophy, it is possible for both vision and thought to achieve a greater awareness of their genealogy through the history of philosophy. The fourteen contributors to Sites of Vision explore the hypothesis that the nature of visual perception about which philosophers talk must be explicitly recognized as a discursive construction, indeed a historical construction, in philosophical discourse.




A Natural History of Vision


Book Description

This illustrated survey covers what Nicholas Wade calls the "observational era of vision," beginning with the Greek philosophers and ending with Wheatstone's description of the stereoscope in the late 1830s.




Vision and Mind


Book Description

The philosophy of perception is a microcosm of the metaphysics of mind. Its central problems—What is perception? What is the nature of perceptual consciousness? How can one fit an account of perceptual experience into a broader account of the nature of the mind and the world?—are at the heart of metaphysics. Rather than try to cover all of the many strands in the philosophy of perception, this book focuses on a particular orthodoxy about the nature of visual perception. The central problem for visual science has been to explain how the brain bridges the gap between what is given to the visual system and what is actually experienced by the perceiver. The orthodox view of perception is that it is a process whereby the brain, or a dedicated subsystem of the brain, builds up representations of relevant figures of the environment on the basis of information encoded by the sensory receptors. Most adherents of the orthodox view also believe that for every conscious perceptual state of the subject, there is a particular set of neurons whose activities are sufficient for the occurrence of that state. Some of the essays in this book defend the orthodoxy; most criticize it; and some propose alternatives to it. Many of the essays are classics. Contributors G.E.M. Anscombe, Dana Ballard, Daniel Dennett, Fred Dretske, Jerry Fodor, H.P. Grice, David Marr, Maurice Merleau-Ponty, Zenon Pylyshyn, Paul Snowdon, and P.F. Strawson




Sites Unseen


Book Description

Sites Unseen challenges conventions for viewing and interpreting the landscape, using visual theory to move beyond traditional practices of describing and classifying objects to explore notions of audience and context. While other fields, such as art history and geography, have engaged poststructuralist theory to consider vision and representation, the application of such inquiry to the natural or built environment has lagged behind. This book, by treating landscape as a spatial, psychological, and sensory encounter, aims to bridge this gap, opening a new dialogue for discussing the landscape outside the boundaries of current art criticism and theory. As the contributors reveal, the landscape is a widely adaptable medium that can be employed literally or metaphorically to convey personal or institutional ideologies. Walls, gates, churchyards, and arches become framing devices for a staged aesthetic experience or to suit a sociopolitical agenda. The optic stimulation of signs, symbols, bodies, and objects combines with physical acts of climbing and walking and sensory acts of touching, smelling, and hearing to evoke an overall "vision" of landscape.Sites Unseen considers a variety of different perspectives, including ancient Roman visions of landscape, the framing techniques of a Moghul palace, and a contemporary case study of Christo's The Gates, as examples of human attempts to shape our sensory, cognitive, and emotional experiences in the landscape.




How Vision Works


Book Description

This book covers all aspects of the visual system from sensory aspects to eye movements, attention, and visual memory in a brief format. Each chapter describes the psychology, followed by where in the brain that aspect is dealt with, the properties of the cells in that area, and what happens if a patient has a lesion or stroke in that area.




Visual Perception


Book Description

This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated.




Techniques of the Observer


Book Description

Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of "subjective vision" were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as "realist," were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s.




Making Eye Health a Population Health Imperative


Book Description

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.




Understanding Vision


Book Description

Vision science has grown hugely in the past decades, but there have been few books showing readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. This book explains the computational principles and models of biological visual processing, and in particular, primate vision.
