Book excerpt: In Stereoblind, no single thing is ever perceived in just one way. Shot through with asymmetry and misconception, the prose poems in Emma Healey’s second collection describe a world that’s anxious and skewed, but still somehow familiar — where the past, present, and future overlap, facts are not always true, borders are not always solid, and events seem to write themselves into being. An on-again, off-again real estate sale nudges a quartet of millennial renters into an alternate universe of multiplying signs and wonders; an art show at Ontario Place may or may not be as strange and complex (or even as “real”) as described; the collusion of a hangover and a blizzard carry our narrator on a trancelike odyssey through Bed Bath & Beyond. Using a diverse range of subjects — from pharmaceutical research testing to Tinder — to form an inventory of ontological disturbance, Healey delves moments when the differences between things disappear, and life exceeds its limits.

Book excerpt: A revelatory account of the brain's capacity for change When neuroscientist Susan Barry was fifty years old, she experienced the sense of immersion in a three dimensional world for the first time. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space. Leaves created intricate mosaics in 3D. Barry had been cross-eyed and stereoblind since early infancy. After half a century of perceiving her surroundings as flat and compressed, on that day she saw the city of Manhattan in stereo depth for first time in her life. As a neuroscientist, she understood just how extraordinary this transformation was, not only for herself but for the scientific understanding of the human brain. Scientists have long believed that the brain is malleable only during a "critical period" in early childhood. According to this theory, Barry's brain had organized itself when she was a baby to avoid double vision - and there was no way to rewire it as an adult. But Barry found an optometrist who prescribed a little-known program of vision therapy; after intensive training, Barry was ultimately able to accomplish what other scientists and even she herself had once considered impossible. Dubbed "Stereo Sue" by renowned neurologist Oliver Sacks, Susan Barry tells her own remarkable journey and celebrates the joyous pleasure of our senses.
Download or read book Do I Know You written by Sadie Dingfelder and published by Little, Brown. This book was released on 2024-06-25 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: An award-winning science writer discovers she’s faceblind and investigates the neuroscience of sight, memory, and imagination—while solving some long-running mysteries about her own life. Science writer Sadie Dingfelder has always known that she’s a little quirky. But while she’s made some strange mistakes over the years, it’s not until she accosts a stranger in a grocery store (whom she thinks is her husband) that she realizes something is amiss. With a mixture of curiosity and dread, Dingfelder starts contacting neuroscientists and lands herself in scores of studies. In the course of her nerdy midlife crisis, she discovers that she is emphatically not neurotypical. She has prosopagnosia (faceblindness), stereoblindness, aphantasia (an inability to create mental imagery), and a condition called severely deficient autobiographical memory. As Dingfelder begins to see herself more clearly, she discovers a vast well of hidden neurodiversity in the world at large. There are so many different flavors of human consciousness, and most of us just assume that ours is the norm. Can you visualize? Do you have an inner monologue? Are you always 100 percent sure whether you know someone or not? If you can perform any of these mental feats, you may be surprised to learn that many people—including Dingfelder—can’t. A lively blend of personal narrative and popular science, Do I Know You? is the story of one unusual mind’s attempt to understand itself—and a fascinating exploration of the remarkable breadth of human experience.

Download or read book Coming to Our Senses written by Susan R. Barry and published by Basic Books. This book was released on 2021-06-08 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A neurobiologist reexamines the personal nature of perception in this groundbreaking guide to a new model for our senses. We think of perception as a passive, mechanical process, as if our eyes are cameras and our ears microphones. But as neurobiologist Susan R. Barry argues, perception is a deeply personal act. Our environments, our relationships, and our actions shape and reshape our senses throughout our lives. This idea is no more apparent than in the cases of people who gain senses as adults. Barry tells the stories of Liam McCoy, practically blind from birth, and Zohra Damji, born deaf, in the decade following surgeries that restored their senses. As Liam and Zohra learned entirely new ways of being, Barry discovered an entirely new model of the nature of perception. Coming to Our Senses is a celebration of human resilience and a powerful reminder that, before you can really understand other people, you must first recognize that their worlds are fundamentally different from your own.

Download or read book Perceiving in Depth Volume 3 Other Mechanisms of Depth Perception written by Ian P. Howard and published by Oxford University Press. This book was released on 2012-01-27 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 3 addresses all depth-perception mechanisms other than stereopsis. The book starts with an account of monocular cues to depth, including accommodation, vergence eye movements, perspective, interposition, shading, and motion parallax. A chapter on constancies in depth perception, such as the ability to perceive the sizes and shapes of objects as they move or rotate in depth, is followed by a chapter on the ways in which depth cues interact. The next chapter reviews sources of information, such as changing disparity, image looming, and vergence eye movements, used in the perception of objects moving in depth. Various pathologies of depth perception, including visual neglect, stereoanomalies, and albanism are reviewed. Visual depth-perception mechanisms through the animal kingdom are described, starting with insects and progressing through crustaceans, fish, amphibians, reptiles, birds, and mammals. The chapter includes a discussion of how stereoscopic vision may have evolved. The next chapter describes how visual depth perception is used to guide reaching movements of the hand, avoiding obstacles, and walking to a distant object. The next three chapters review non-visual mechanisms of depth perception. Auditory mechanisms include auditory localization, echolocation in bats and marine mammals, and the lateral-line system of fish. Some fish emit electric discharges and then use electric sense organs to detect distortions of the electric field produced by nearby objects. Some beetles and snakes use heat-sensitive sense organs to detect sources of heat. The volume ends with a discussion of mechanisms used by animals to navigate to a distant site. Ants find their way back to the nest by using landmarks and by integrating their walking movements. Several animals navigate by the stars or by polarized sunlight. It seems that animals in several phyla navigate by detecting the Earths magnetic field.
Download or read book Vision and the Visual System written by Peter H. Schiller and published by Oxford University Press. This book was released on 2015-07-17 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision and the Visual System offers students, teachers, and researchers a rigorous, yet accessible account of how the brain analyzes the visual scene. Schiller and Tehovnik describe key aspects of visual perception while explaining the relationship between eye movements and the neural structures in the brain, which play a central role in how we process visual information. The book discusses various brain areas involved in processing information, focusing on the evolutionary origins and mechanics behind the several parallel pathways that compose the visual system. Later chapters explain how the nervous system processes the perception of color, motion, depth, and patterns. A variety of illusions are on display in Chapter 14, where the authors provide detailed explanations that deconstruct how the visual system operates to create them. The volume concludes with a discussion of recent attempts to build visual prosthetic devices for blind individuals, of which there are more than 40 million in the world. Vision and the Visual System is based on Professor Schiller's more than 40 years of experience teaching vision courses at MIT, and is tailored especially for college undergraduates and graduate students interested in visual perception and the operations of the visual system. The Dynamic Displays posted here for this book are short video clips that would enhance the reader to understand certain areas of vision. They are particular to the chapter they belong within (9 video clips for Chapter 11, 1 video clip for Chapter 12, and 2 video clips for Chapter 14). http://web.mit.edu/bcs/schillerlab/book.html
Download or read book Stereoblind written by Janine Hildbrand and published by . This book was released on 2010 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the abstract of the Matura paper submitted by Janine Hildbrand at 3 December 2010, supervised by Dr. Daniel Schläpfer. My hypothesis is that stereoblindness has a considerable impact on daily life situations. The aim of this paper is to prove this impact by specifically designed experiments. It is known that you need to have two eyes that work together to see the world in its three dimensions. However, you do not see the world flat if you look at it through one eye only, since there are also depth cues that you can perceive. That is because depth perception and three-dimensional viewing are not the same. The test persons had to do five experiments with one eye covered to simulate being stereoblind. They are divided into three age categories, namely children, teenagers and adults. They had to walk down the stairs with different height of steps, pass a frisbee once with normal vision and once with only two-dimensional vision, play boccia where one saw the three dimensions while the other did not, play table tennis under the same conditions, pour water from a litre beaker into a bottle without dripping and close a felt pen at the first try. The result is that stereovision has a big impact on these situations except on playing boccia because stereopsis only has to be considered within near distances.

Download or read book Human Factors of Stereoscopic 3D Displays written by Robert Earl Patterson, Ph.D. and published by Springer. This book was released on 2015-02-18 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human Factors of Stereoscopic Displays provides an overview of all vision-relevant topics and issues that inform stereo display design from a user-centric or human factor, perspective. Although both the basic vision science literature and the applied literature will be reviewed, the strength and originality of this book comes from the emphasis on the basic science literature on human stereo vision and its implications for stereo display design. The reader will learn how to design stereo displays from a human vision/human factors perspective. Over the past several years, there has been a growing interest in the development of high-quality displays that present binocular parallax information to the human visual system for inducing the perception of three-dimensional depth. The methods for presenting binocular parallax to an observer vary widely and include three broad categories of display: stereoscopic, holographic and volumetric displays. Because the technology for stereoscopic displays is more developed and more widely used, than those based on holography or volumetric methods, the proposed book addresses those human factors issues involved in the viewing of stereoscopic displays. Despite the diverse methods for creating stereoscopic displays, which includes stereo spatial multiplexing as well as temporal multiplexing (i.e., field sequential) techniques, there remain common human factor issues that arise when viewing such displays. Human Factors of Stereoscopic Displays will provide a detailed review of these important issues so that they can be considered when designing and using 3D displays. In doing so, the following topics will be covered: interocular cross talk; interocular differences in luminance and contrast; accommodation-vergence mismatch; stereoanomaly; spatio-temporal frequency effects; distance scaling of disparity and high-level cue conflict. body>

Download or read book Begin with the End in Mind written by Emma Healey and published by Arp Books. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Residing on the border between poetry and prose, Emma Healey masterfully navigates the tension and balance between the two forms. Her writing examines the animate qualities of seemingly inanimate things and explores personal relationships, collective and individual human experiences, as they are distilled through our encounters with such things as the CBC, chain bookstores, the contents of a kitchen, or the expanse of a whole city. Begin With the End in Mind tests the capabilities of the prose poem--the specific rhythmic, lyrical, and syntactic possibilities of the form, and the opportunities for play, renegotiating the more traditional/technical elements of lyric and line that are afforded the prose poet.
Download or read book Visual Coding and Adaptability written by C. S. Harris and published by Psychology Press. This book was released on 2014-02-25 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1980. This book is the first integrated presentation of two of the most active areas in present-day visual research. Its inspiration and nucleus were provided by two Optical Society of America symposia, one on the coding of spatial information in the visual system and the other on adaptability of the visual system. Although the two topics might seem, at first sight, only distantly related, they are actually extensively intertwined in contemporary research. Some investigators focus on mechanisms of visual analysis but rely on experimental modification of perception to reveal the nature of the coding; others focus on perceptual modification but look at analytic elements for indications about what it is that gets modified. Likewise, most of the chapters in this book combine, in varying proportions, both themes. Adult human perception is the primary concern, but illuminating data from animal, infant, and neurophysiological studies are also discussed.
