Advances in sensing, signal processing, and computer technology during the past half century have stimulated numerous attempts to design general-purpose ma chines that see. These attempts have met with at best modest success and more typically outright failure. The difficulties encountered in building working com puter vision systems based on state-of-the-art techniques came as a surprise. Perhaps the most frustrating aspect of the problem is that machine vision sys tems cannot deal with numerous visual tasks that humans perform rapidly and effortlessly. In reaction to this perceived discrepancy in performance, various researchers (notably Marr, 1982) suggested that the design of machine-vision systems should be based on principles drawn from the study of biological systems. This "neuro morphic" or "anthropomorphic" approach has proven fruitful: the use of pyramid (multiresolution) image representation methods in image compression is one ex ample of a successful application based on principles primarily derived from the study of biological vision systems. It is still the case, however, that the perfor of computer vision systems falls far short of that of the natural systems mance they are intended to mimic, suggesting that it is time to look even more closely at the remaining differences between artificial and biological vision systems.

The Third Edition of Understanding and Managing Vision Deficits is the go-to resource that will enable occupational therapists to develop a comprehensive understanding of vision, appreciate the various effects vision problems can have on the practice of occupational therapy, and to more effectively manage patients with vision disorders. Understanding and Managing Vision Deficits: A Guide for Occupational Therapists, Third Editionis a unique collaboration from occupational therapists, optometrists, and low vision rehabilitation specialists. Dr. Mitchell Scheiman presents a unique Three Component Model of Vision that includes: Visual integrity: Includes visual acuity (clarity), the optics of the eye, and eye health Visual efficiency skills: Includes focusing, eye teaming, and eye movements Visual information processing skills: Includes the ability to analyze, interpret and respond to visual information A major emphasis of the new edition is on management of eye movement, visual information processing, visual field, and low vision problems. Therapy suggestions have been expanded and the use of computer software has been incorporated into the therapy. Some Additional Chapter Topics Include: Visual problems associated with learning disorders Visual problems associated with acquired brain injury Management of vision problems for children with special needs Low vision Features of the Third Edition: Updated figures, research, and references Incorporates current American Occupational Therapy Association Practice Framework Glossary of key terms Appendices that include a vision screening report form and low vision supplies and equipment Understanding and Managing Vision Deficits: A Guide for Occupational Therapists, Third Edition will continue to bring the professions of occupational therapy and optometry together and will guide health care professionals to provide the ultimate in patient care.

Vision, more than any other sense, dominates our mental life. Our conscious visual experience of the world is so rich and detailed that we can hardly distinguish it from the real thing. But as Goodale and Milner make clear in their prize-winning book, Sight Unseen, our visual experience of the world is not all there is to vision. Some of the most important things that vision does for us never reach our consciousness at all. In this updated and extended new edition, Goodale and Milner explore one of the most extraordinary neurological cases of recent years—one that profoundly changed scientific views on the visual brain. It is the story of Dee Fletcher—a young woman who became blind to shape and form as a result of brain damage. Dee was left unable to recognize objects or even tell one simple geometric shape from another. As events unfolded, however, Goodale and Milner found that Dee wasn't in fact blind — she just didn't know that she could see. They showed, for example, that Dee could reach out and grasp objects with amazing dexterity, despite being unable to perceive their shape, size, or orientation. Taking us on a journey into the unconscious brain, the two scientists who made this incredible discovery tell the amazing story of their work, and the surprising conclusion they were forced to reach. Written to be accessible to students and popular science readers, this book is a fascinating illustration of the power of the 'unconscious' mind.

‘How do children see the world?’ is a question of immense importance which fascinates not only psychologists but also parents and all those concerned with education. In this English translation, first published in 1976, the author, who was Professor of Psychology at the René Descartes University in Paris, provided the most comprehensive review at the time of the development of visual perception in children, a field to which she herself had made a substantial contribution. Her book, which gave the first comprehensive study of the relationship between cognitive development and perceptual activities in small children, explores how they interpret visual information and gradually build up a picture of the world. The author had devoted fifteen years to research on the visual world of the child and possessed an exhaustive knowledge of the experimental literature on the subject in English, French, Russian and other languages. She saw perception as a form of knowledge which the child exploits and adapts in a variety of ways at different stages of development. This is brilliantly demonstrated in her own research on the strategies children use in judging things as ‘different’ or ‘the same’ and the way these relate to the structure of their perceptual organisation. This book is essential reading for anyone with a serious interest in developmental and cognitive psychology; it also provides an object lesson in the application of experimental methods. In addition the organisation of the material made it a valuable textbook for advanced undergraduate and post-graduate teaching and will still be of interest in its historical context today.

The dominance of vision is so strong in sighted people that touch is sometimes considered as a minor perceptual modality. However, touch is a powerful tool which contributes significantly to our knowledge of space and objects. Its intensive use by blind persons allows them to reach the same levels of knowledge and cognition as their sighted peers.In this book, specialized researchers present the recent state of knowledge about the cognitive functioning of touch. After an analysis of the neurophysiology and neuropsychology of touch, exploratory manual behaviors, intramodal haptic (tactual-kinesthetic) abilities and cross-modal visual-tactual coordination are examined in infants, children and adults, and in non-human primates. These studies concern both sighted and blind persons in order to know whether early visual deprivation modifies the modes of processing space and objects. The last section is devoted to the technical devices favoring the school and social integration of the young blind: Braille reading, use of raised maps and drawings, “sensory substitution” displays, and new technologies of communication adapted for the blind.

The book analyses the differences between the mathematical interpretation and the phenomenological intuition of the continuum. The basic idea is that the continuity of the experience of space and time originates in phenomenic movement. The problem of consciousness and of the spaces of representation is related to the primary processes of perception. Conceived as an interplay between cognitive science, linguistics and philosophy, the book presents a conceptual framework based on a dynamic and experimental approach to the problem of the continuum. Besides presenting the primitives of a theory of cognitive space and time, it presents a theory of the observer, analyzing the relationship among perspective, points of view and unity of consciousness. The book's chapters deal with the dynamic elaboration and recognition of forms from the lower to the higher processes in the various perceptual fields. Experimental analysis from visual, auditory and tactile perception outline the basic structures of intentionality and its counterpart in language and gesture. (Series B)

This work proposes a novel view to explain how we as humans can have the impression of consciously feeling things: for example the red of a sunset, the smell of a rose, the sound of a symphony, or a pain.
