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.

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.
