Vision science has grown hugely in the past decades, but there have been few books showing readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. This book explains the computational principles and models of biological visual processing, and in particular, primate vision.

Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.

While the field of vision science has grown significantly in the past three decades, there have been few comprehensive books that showed readers how to adopt a computional approach to understanding visual perception, along with the underlying mechanisms in the brain. Understanding Vision explains the computational principles and models of biological visual processing, and in particular, of primate vision. The book is written in such a way that vision scientists, unfamiliar with mathematical details, should be able to conceptually follow the theoretical principles and their relationship with physiological, anatomical, and psychological observations, without going through the more mathematical pages. For those with a physical science background, especially those from machine vision, this book serves as an analytical introduction to biological vision. It can be used as a textbook or a reference book in a vision course, or a computational neuroscience course for graduate students or advanced undergraduate students. It is also suitable for self-learning by motivated readers. in addition, for those with a focused interest in just one of the topics in the book, it is feasible to read just the chapter on this topic without having read or fully comprehended the other chapters. In particular, Chapter 2 presents a brief overview of experimental observations on biological vision; Chapter 3 is on encoding of visual inputs, Chapter 5 is on visual attentional selection driven by sensory inputs, and Chapter 6 is on visual perception or decoding. Including many examples that clearly illustrate the application of computational principles to experimental observations, Understanding Vision is valuable for students and researchers in computational neuroscience, vision science, machine and computer vision, as well as physicists interested in visual processes.

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Designed for students, scientists and engineers interested in learning about the core ideas of vision science, this volume brings together the broad range of data and theory accumulated in this field.

A thorough review that covers fundamentals, assessment, clinical services, training and instructional services, and future directions. The author establishes a framework for understanding the impact of low vision on functioning, learning, and psychosocial status. Special sections contain chapters, reports, technical materials, curriculum guides, resources, and questionnaires by experts from 21 areas.

Gregory Bateson was one of the most original social scientists of this century. He is widely known as author of key ideas used in family therapy - including the well-known condition called 'double bind' . He was also one of the most influential figures in cultural anthropology. In the decade before his death in 1980 Bateson turned toward a consideration of ecology. Standard ecology concentrates on an ecosystem's biomass and on energy budgets supporting life. Bateson came to the conclusion that understanding ecological organization requires a complete switch in scientific perspective. He reasoned that ecological phenomena must be explained primarily through patterns of information and that only through perceiving these informational patterns will we uncover the elusive unity, or integration, of ecosystems. Bateson believed that relying upon the materialist framework of knowledge dominant in ecological science will deepen errors of interpretation and, in the end, promote eco-crisis. He saw recursive patterns of communication as the basis of order in both natural and human domains. He conducted his investigation first in small-scale social settings; then among octopus, otters, and dolphins. Later he took these investigations to the broader setting of evolutionary analysis and developed a framework of thinking he called 'an ecology of mind.' Finally, his inquiry included an ecology of mind in ecological settings - a recursive epistemology. This is the first study of the whole range of Bateson's ecological thought - a comprehensive presentaionof Bateson's matrix of ideas. Drawing on unpublished letters and papers, Harries-Jones clarifies themes scattered throughout Bateson's own writings, revealing the conceptual consistency inherent in Bateson's position, and elaborating ways in which he pioneered aspects of late twentieth-century thought.
