Book excerpt: Advances in technology allow us to see the invisible: fetal heartbeats, seismic activity, cell mutations, virtual space. Yet in an age when experience is so intensely mediated by visual records, the centuries-old realization that knowledge gained through sight is inherently fallible takes on troubling new dimensions. This book considers the ways in which seeing, over time, has become the foundation for knowing (or at least for what we think we know). A. Joan Saab examines the scientific and socially constructed aspects of seeing in order to delineate a genealogy of visuality from the Renaissance to the present, demonstrating that what we see and how we see it are often historically situated and culturally constructed. Through a series of linked case studies that highlight moments of seeming disconnect between seeing and believing—hoaxes, miracles, spirit paintings, manipulated photographs, and holograms, to name just a few—she interrogates the relationship between “visions” and visuality. This focus on the strange and the wonderful in understanding changing notions of visions and visual culture is a compelling entry point into the increasingly urgent topic of technologically enhanced representations of reality. Accessibly written and thoroughly enlightening, Objects of Vision is a concise history of the connections between seeing and knowing that will appeal to students and teachers of visual studies and sensory, social, and cultural history.

Available in PDF, EPUB and Kindle. Book excerpt: Spotting a face in a crowd is so easy, you take it for granted. But how you do it is one of science's great mysteries. Vision is involved in nearly a third of everything a brain does and explaining how it works reveals more than just how we see. It also tells us how the brain processes information – how it perceives, learns and remembers. In We Know It When We See It, pioneering neuroscientist Richard Masland covers everything from what happens when light hits your retina, to the increasingly sophisticated nerve nets that turn that light into knowledge, to what a computer algorithm must be able to do before it can truly be called ‘intelligent’. It is a profound yet accessible investigation into how our bodies make sense of the world.

Book excerpt: Cutting-edge research on the visual cognition of scenes, covering issues that include spatial vision, context, emotion, attention, memory, and neural mechanisms underlying scene representation. For many years, researchers have studied visual recognition with objects—single, clean, clear, and isolated objects, presented to subjects at the center of the screen. In our real environment, however, objects do not appear so neatly. Our visual world is a stimulating scenery mess; fragments, colors, occlusions, motions, eye movements, context, and distraction all affect perception. In this volume, pioneering researchers address the visual cognition of scenes from neuroimaging, psychology, modeling, electrophysiology, and computer vision perspectives. Building on past research—and accepting the challenge of applying what we have learned from the study of object recognition to the visual cognition of scenes—these leading scholars consider issues of spatial vision, context, rapid perception, emotion, attention, memory, and the neural mechanisms underlying scene representation. Taken together, their contributions offer a snapshot of our current knowledge of how we understand scenes and the visual world around us. Contributors Elissa M.

Available in PDF, EPUB and Kindle. Book excerpt: In The Vision Revolution: How the Latest Research Overturns Everything We Thought We Knew About Human Vision, Mark Changizi, prominent neuroscientist and vision expert, addresses four areas of human vision and provides explanations for why we have those particular abilities, complete with a number of full-color illustrations to demonstrate his conclusions and to engage the reader. Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field's most recent research. Changizi focuses on four “why" questions: 1. Why do we see in color? 2. Why do our eyes face forward? 3. Why do we see illusions? 4. Why does reading come so naturally to us? Why Do We See in Color? It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi's research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it's no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans. Why Do Our Eyes Face Forward? Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi's research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we're able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You'll find that you're able to look “through" it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren't blocked by our noses, beaks, etc. Why Do We See Illusions? We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn't catch a ball because the brain's ability to process visual information isn't fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past," Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving" element into the future and, as a result, we don't see what's on the page, but what our brain thinks will be the case a fraction of a second into the future. Why Does Reading Come So Naturally to Us? We can read faster than we can hear, which is odd, considering that reading is relatively recent,

Book excerpt: Vision is the sense by which we and other animals obtain most of our information about the world around us. Darwin appreciated that at first sight it seems absurd that the human eye could have evolved by natural selection. But we now know far more about vision, the many times it has independently evolved in nature, and the astonishing variety of ways to see. The human eye, with a lens forming an image on a sensitive retina, represents just one. Scallops, shrimps, and lobsters all use mirrors in different ways. Jumping spiders scan with their front-facing eyes to check whether the object in front is an insect to eat, another spider to mate with, or a predator to avoid. Mantis shrimps can even measure the polarization of light. Animal eyes are amazing structures, often involving precision optics and impressive information processing, mainly using wet protein - not the substance an engineer would choose for such tasks. In Eyes to See, Michael Land, one of the leading world experts on vision, explores the varied ways in which sight has evolved and is used in the natural world, and describes some of the ingenious experiments researchers have used to uncover its secrets. He also discusses human vision, including his experiments on how our eye movements help us to do everyday tasks, as well as skilled ones such as sight-reading music or driving. He ends by considering the fascinating problem of how the constantly shifting images from our eyes are converted in the brain into the steady and integrated conscious view of the world we experience.

NOMINATED FOR 16 STATE AWARDS! AN ALA NOTABLE BOOK AN ILA TEACHERS CHOICE A KIRKUS REVIEWS BEST BOOK OF THE YEAR Arthur T. Owens grabbed a brick and hurled it at the trash picker. Arthur had his reasons, and the brick hit the Junk Man in the arm, not the head. But none of that matters to the judge—he is ready to send Arthur to juvie forever. Amazingly, it’s the Junk Man himself who offers an alternative: 120 hours of community service . . . working for him. Arthur is given a rickety shopping cart and a list of the Seven Most Important Things: glass bottles, foil, cardboard, pieces of wood, lightbulbs, coffee cans, and mirrors. He can’t believe it—is he really supposed to rummage through people’s trash? But it isn’t long before Arthur realizes there’s more to the Junk Man than meets the eye, and the “trash” he’s collecting is being transformed into something more precious than anyone could imagine. . . . Inspired by the work of folk artist James Hampton, Shelley Pearsall has crafted an affecting and redemptive novel about discovering what shines within us all, even when life seems full of darkness. “A moving exploration of how there is often so much more than meets the eye.” —Booklist, starred review “There are so many things to love about this book.

Book excerpt: An engaging introduction to the science of vision that offers a coherent account of vision based on general information processing principles In this accessible and engaging introduction to modern vision science, James Stone uses visual illusions to explore how the brain sees the world. Understanding vision, Stone argues, is not simply a question of knowing which neurons respond to particular visual features, but also requires a computational theory of vision. Stone draws together results from David Marr's computational framework, Barlow's efficient coding hypothesis, Bayesian inference, Shannon's information theory, and signal processing to construct a coherent account of vision that explains not only how the brain is fooled by particular visual illusions, but also why any biological or computer vision system should also be fooled by these illusions. This short text includes chapters on the eye and its evolution, how and why visual neurons from different species encode the retinal image in the same way, how information theory explains color aftereffects, how different visual cues provide depth information, how the imperfect visual information received by the eye and brain can be rescued by Bayesian inference, how different brain regions process visual information, and the bizarre perceptual consequences that result from damage to these brain regions. The tutorial style emphasizes key conceptual insights, rather than mathematical details, making the book accessible to the nonscientist and suitable for undergraduate or postgraduate study.

Book excerpt: Thomas Sowell’s “extraordinary” explication of the competing visions of human nature lie at the heart of our political conflicts (New York Times) Controversies in politics arise from many sources, but the conflicts that endure for generations or centuries show a remarkably consistent pattern. In this classic work, Thomas Sowell analyzes this pattern. He describes the two competing visions that shape our debates about the nature of reason, justice, equality, and power: the "constrained" vision, which sees human nature as unchanging and selfish, and the "unconstrained" vision, in which human nature is malleable and perfectible. A Conflict of Visions offers a convincing case that ethical and policy disputes circle around the disparity between both outlooks.

Available in PDF, EPUB and Kindle. Book excerpt: Almost every organization has a vision. Few ever accomplish it. Even after short-term success in it, fewer stay true to it over time. Be Mean: Relentlessly Protecting the Vision is about regaining or sustaining the trajectory of the vision over time. It’s about staying true to the vision. Lovejoy explains that this requires understanding the importance of vision, developing a vision we’re willing to die for, and keeping the vision from being compromised or even hijacked. Though many books have been written on the subject of developing mission or vision statements, there have been few written on how to sustain or protect the vision over time. Shawn has dealt with hundreds of leaders in ministry and has seen countless struggle with keeping everyone on board with the mission and how to align the rest of the organization with the vision. Shawn Lovejoy walks the church leader through the experiences that have taught him to Be Mean, and shows us a strategy of Relentlessly Protecting the Vision.

Download or read book Seeing, second edition written by John P. Frisby and published by MIT Press. This book was released on 2010-04-02 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible yet rigorous and generously illustrated exploration of the computational approach to the study of biological vision. Seeing has puzzled scientists and philosophers for centuries and it continues to do so. This new edition of a classic text offers an accessible but rigorous introduction to the computational approach to understanding biological visual systems. The authors of Seeing, taking as their premise David Marr's statement that “to understand vision by studying only neurons is like trying to understand bird flight by studying only feathers,” make use of Marr's three different levels of analysis in the study of vision: the computational level, the algorithmic level, and the hardware implementation level. Each chapter applies this approach to a different topic in vision by examining the problems the visual system encounters in interpreting retinal images and the constraints available to solve these problems; the algorithms that can realize the solution; and the implementation of these algorithms in neurons. Seeing has been thoroughly updated for this edition and expanded to more than three times its original length. It is designed to lead the reader through the problems of vision, from the common (but mistaken) idea that seeing consists just of making pictures in the brain to the minutiae of how neurons collectively encode the visual features that underpin seeing. Although it assumes no prior knowledge of the field, some chapters present advanced material. This makes it the only textbook suitable for both undergraduate and graduate students that takes a consistently computational perspective, offering a firm conceptual basis for tackling the vast literature on vision. It covers a wide range of topics, including aftereffects, the retina, receptive fields, object recognition, brain maps, Bayesian perception, motion, color, and stereopsis. MatLab code is available on the book's website, which includes a simple demonstration of image convolution.

Available in PDF, EPUB and Kindle. Book excerpt: The Female Vision shows why: • What women see matters to organizations • What women notice is what organizations need now • What women value Will Define Organizational Excellence in The Future Women often see the world from a different angle than men. But this fact has been overlooked in most organizations. In this brilliant and strongly argued new book, Sally Helgesen and Julie Johnson demonstrate why “the female vision”—what women notice, what they value, how they connect the dots—constitutes women's most powerful asset in the workplace. Drawing on multiple strands of research, including their own Satisfaction Profile Assessment, they show what companies must do to engage, energize, and support talented women. And they show women how to nurture and sustain their own greatest gifts.
