When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.

This antiquarian book contains a treatise on the importance and influence of vision in the development of infants and children. Cinemanalysis has demonstrated that the eyes play an important role in the ontogenesis of the total action system of the child, and the nature and dynamics of that role constitute the subject matter of the present study. This is a text that will appeal to those with a keen interest in the science of human development and the importance of vision and the eye therein, and it world make for a worthy addition to collections of allied literature. The chapters of this book include: 'The Visual Domain', 'The Complex of Visual Functions', 'The Young Eye in Action', 'The Ontogenesis of Visual Behavior', 'Maldevelopment and Child Vision', 'A Developmental Hygiene of Child Vision', 'The Conservation of Child Vision', etcetera. We are republishing this vintage book now complete with a new prefatory biography of the author.

The study of visual development has proceeded at a rapid pace in recent years, and there have been theoretical and methodological innovations across a wide range of disciplines. This book brings together some of the most recent innovations from a neurobiological perspective. Chapters cover the pre- to postnatal development of vision, new insights into the concept of critical periods, object and face recognition, as well as dynamic perception and visual recognition memory in infants. The volume finishes with a detailed overview of the development of visual functions from the perspective of neural network modeling. This book will appeal to psychologists, visual scientists and infancy researchers with an interest in development of the visaul system from a multidisciplinary perspective. An integrative introduction is followed by chapters that challenge thinking about development in terms of a nativist-empiricist dichotomy. Emphasis is on cross-disciplinary research links and between chapters readers will find cross-references.

This extensive book provides an up-to-date overview by leading international authorities, spanning the disciplines of neuroscience, psychology, ophthalmology, optometry, and paediatrics, of normal and pathological infant visual development. It covers the development of retinal receptors;infant sensitivity to detail, colour, contrast, and movement; binocularity, eye movements, and refraction, and cognitive processing. Childrens' visual deficits, including amblyopia and cataract are covered.

Manual for Child and Vision Development Milestones is a precious guide that discusses the physical, social, motor, cognitive, and emotional development that occurs from birth through early adulthood, for children with and without vision. It also discusses the possible effects of maltreatment on child and vision development. This book contains the most recent researched theories, and findings of child and vision development, investigated by psychologists and eye care professionals. The content is designed to educate and guide a broad range of readers (students, parents, child specialists, etc.) on developmental norms at different stages of a child's life.
