An investigation of the effects of blindness and other types of visual deficit on cognitive abilities. Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain—as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.
Excerpt from Which Hand Is the Eye of the Blind?: From the Psychological Laboratory of the University of Missouri The embossed printing invented by Hauy, however, was not easily read by the blind. James Gall, of Edin burgh, improved it by making the letters larger, more open and angular, and by printing them in high relief. This was called the triangular system because Of the prevalence Of triangles within it. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

A compelling argument for including the human perspective within science, and for how human experience makes science possible. It’s tempting to think that science gives us a God’s-eye view of reality. But we neglect the place of human experience at our peril. In The Blind Spot, astrophysicist Adam Frank, theoretical physicist Marcelo Gleiser, and philosopher Evan Thompson call for a revolutionary scientific worldview, where science includes—rather than ignores or tries not to see—humanity’s lived experience as an inescapable part of our search for objective truth. The authors present science not as discovering an absolute reality but rather as a highly refined, constantly evolving form of human experience. They urge practitioners to reframe how science works for the sake of our future in the face of the planetary climate crisis and increasing science denialism. Since the dawn of the Enlightenment, humanity has looked to science to tell us who we are, where we come from, and where we’re going, but we’ve gotten stuck thinking we can know the universe from outside our position in it. When we try to understand reality only through external physical things imagined from this outside position, we lose sight of the necessity of experience. This is the Blind Spot, which the authors show lies behind our scientific conundrums about time and the origin of the universe, quantum physics, life, AI and the mind, consciousness, and Earth as a planetary system. The authors propose an alternative vision: scientific knowledge is a self-correcting narrative made from the world and our experience of it evolving together. To finally “see” the Blind Spot is to awaken from a delusion of absolute knowledge and to see how reality and experience intertwine. The Blind Spot goes where no science book goes, urging us to create a new scientific culture that views ourselves both as an expression of nature and as a source of nature’s self-understanding, so that humanity can flourish in the new millennium.
The incredible bestselling book from the author of No Barriers and The Adversity Advantage Erik Weihenmayer was born with retinoscheses, a degenerative eye disorder that would leave him blind by the age of thirteen. But Erik was determined to rise above this devastating disability and lead a fulfilling and exciting life. In this poignant and inspiring memoir, he shares his struggle to push past the limits imposed on him by his visual impairment-and by a seeing world. He speaks movingly of the role his family played in his battle to break through the barriers of blindness: the mother who prayed for the miracle that would restore her son's sight and the father who encouraged him to strive for that distant mountaintop. And he tells the story of his dream to climb the world's Seven Summits, and how he is turning that dream into astonishing reality (something fewer than a hundred mountaineers have done). From the snow-capped summit of McKinley to the towering peaks of Aconcagua and Kilimanjaro to the ultimate challenge, Mount Everest, this is a story about daring to dream in the face of impossible odds. It is about finding the courage to reach for that ultimate summit, and transforming your life into something truly miraculous. "An inspiration to other blind people and plenty of us folks who can see just fine."—Jon Krakauer, New York Times bestselling author of Into Thin Air
