How the perception of shadows, studied by vision scientists and visual artists, reveals the inner workings of the visual system. In The Visual World of Shadows, Roberto Casati and Patrick Cavanagh examine how the perception of shadows, as studied by vision scientists and visual artists, reveals the inner workings of the visual system. Shadows are at once a massive problem for vision—which must distinguish them from objects or material features of objects—and a resource, signaling the presence, location, shape, and size of objects. Casati and Cavanagh draw up an inventory of information retrievable from shadows, showing their amazing variety. They present an overview of the visual system, distinguishing between measurement and inference. They discuss the shadow mission, the work done by the visual brain to parse, and perhaps discard, the information from shadows; shadow ownership, the association of a shadow with the object that casts it; shadow labeling, the visual system's ability to tell shadows from nonshadows; and the shadow concept, our knowledge about shadows as a category. Casati and Cavanagh then apply the theoretical apparatus they have developed for shadows to other phenomena: illumination, reflection, and transparency. Finally, they examine the art of the shadow, paying tribute to artists' exploration of shadow, analyzing a series of artworks (reproduced in color) from a rich and fascinating art historical corpus.

Many artists and scientists – including Buffon, Goethe, and Philipp Otto Runge – who observed the vividly coloured shadows that appear outdoors around dawn and dusk, or indoors when a candle burns under waning daylight, chose to describe their colours as ‘beautiful’. Paul Smith explains what makes these ephemeral effects worthy of such appreciation – or how depictions of coloured shadows have genuine aesthetic and epistemological significance. This multidisciplinary book synthesises methodologies drawn from art history (close pictorial analysis), psychology and neuroscience (theories of colour constancy), history of science (the changing paradigms used to explain coloured shadows), and philosophy (theories of perception and aesthetic value drawn from Wittgenstein and Merleau-Ponty). This title will be of interest to scholars in art history, art theory, and the history of science and technology.

As the general notion of cognition has recently broadened to include its embodied nature, researchers' accounts of perception have increasingly come to include the body's special status as a window on the world and to accommodate the specific perceptual requirements for identifying, interpreting, and interacting with other bodies. This volume presents a comprehensive overview of the rapid progress that has been made in understanding the human body and its relationship to perception. It will help to unify the relevant research from several independent areas of cognitive psychology and cognitive neuroscience and facilitate the development of an integrated framework for the study of human-body perception.

Bayesian probability theory has emerged not only as a powerful tool for building computational theories of vision, but also as a general paradigm for studying human visual perception. This 1996 book provides an introduction to and critical analysis of the Bayesian paradigm. Leading researchers in computer vision and experimental vision science describe general theoretical frameworks for modelling vision, detailed applications to specific problems and implications for experimental studies of human perception. The book provides a dialogue between different perspectives both within chapters, which draw on insights from experimental and computational work, and between chapters, through commentaries written by the contributors on each others' work. Students and researchers in cognitive and visual science will find much to interest them in this thought-provoking collection.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do. The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.

Shadows are holes in light. We see them all the time, and sometimes we notice them, but their part in our visual experience of the world is mysterious. In this book, an art historian draws on contemporary cognitive science, eighteenth-century theories of visual perception, and art history to discuss shadows and the visual knowledge they can offer.

A robbery victim tries to remember how the crime unfolded and who was present at the scene. A medical patient recalls the doctor saying that the pain in her side wasn't worrisome, and now that the tumor is much larger, she's suing. An investigation of insider trading hinges on someone's memory of exactly what was said at a particular business meeting. In these and countless other examples, our ability to remember our experiences is crucial for the justice system. The problem, though, is that perception and memory are fallible. How often do our eyes or memories deceive us? Is there some way to avoid these errors? Can we specify the circumstances in which perceptual or memory errors are more or less likely to occur? Professor Daniel Reisberg tackles these questions by drawing on the available science and his personal experience training attorneys. He provides detailed pragmatic advice that will prove helpful to law enforcement, prosecutors, defenders, and anyone else who hopes to maximize the quality of the evidence available to the courts -- whether the evidence is coming from witnesses, victims, or defendants. This book is carefully rooted in research but written in a way that will make it fully accessible to non-scientists working in the justice system. Early chapters provide an overview of the relevant science and a broad portrait of how perception and memory function. Later chapters offer practical solutions for navigating situations involving eyewitness identifications, remembered conversations, evidence obtained from interviews with children, confession evidence, and the risks of false confession.
