Relationships between infant visual skills and the development of object permanence and expressive language skills were examined with 31 infants in three groups: visually typical, visually atypical, and Down Syndrome. Measures used to evaluate visual status were: forced preferential looking, optokinetic nystagmus, and behavioral. Object permanence…

USING A SAMPLE OF 94 CHILDREN (31 TO 54 MONTHS OLD), THIS STUDY COMPARED EIGHT VISION SCREENING PROCEDURES FOR YOUNG CHILDREN IN THE ABILITY TO TEST FOR SEVERAL VISUAL FUNCTIONS, AND PREFERENCE AMONG THEM BY CHILDREN. THE SUBJECTS WERE ORIGINALLY TESTED USING THE EIGHT SCREENING TESTS, AND 6 MONTHS LATER 40 OF THE CHILDREN WERE RETESTED FOR…

THE SUBJECT OF THIS EXPERIMENTAL PROGRAM WAS THE RECOGNITION OF, OR CONCEPTUAL RESPONSE TO, COMPLEX VISUAL STIMULI BY COLLEGE STUDENTS. PROGRAMED INSTRUCTIONAL TECHNIQUES WERE USED IN THE SUBJECT CONTEXT TO DEVELOP PRELIMINARY SELF-TEACHING MATERIALS FOR LEARNING COMPLEX CONCEPTS. THESE PROGRAMING TECHNIQUES WERE IMPLEMENTED TO PRODUCE VISUAL…

A validation study of the vision test battery used in the Health Examination Survey of 1966-1970 was conducted among 210 youths 12-17 years-old who had been part of the larger survey. The study was designed to discover the degree of correspondence between survey test results and clinical examination by an opthalmologist in determining the…

The author describes potential problems in the classroom use of distance low vision aids (including the ring telescope and closed circuit television) with visually impaired children 5-13 years old, and emphasizes the need for cooperation between the teacher and the prescribing physician. (CL)

The study assesses the impact of a visual screening effort using the Ophthalmetron (a device which permits rapid screening for refractive error) on 550 kindergarten through eighth-grade students. Findings showed that only 38 percent of those children referred to an ophthalmologist actually went. (PHR)

Three experiments examined the ability of blind individuals and individuals simulating the visual acuity of 20/400 to monitor the behaviors of a cane traveler in various environments and at distances between 10 feet and 25 feet. Results suggested that at least some vision is needed for instructors monitoring visually impaired individuals learning…

This paper presents a summary of presentations and discussion from a World Health Organization meeting of experienced low vision practitioners. It outlines the magnitude of the problem; current status of low vision care; enhancement of the use of vision; and recommendations in definitions, identification, assessment, low vision centers, education,…

Describes an experiment in which students work together in small groups, take data, and make a calculation to roughly determine the diameter of the blind spot in their eye. (WRM)

The efficiency of teaching algorithms can be highly improved by utilizing the senses as educational aids. The authors have developed a new didactical method and a software tool which exemplifies, for the case of simple algorithms, how the involvement of eyesight, hearing and the kinaesthesia can help in the teaching and learning process. This…

This systematic review of the effectiveness of driver rehabilitation interventions found that driver training programs enhance driving skills and awareness, but further research is needed to determine their effectiveness in improving driving performance of drivers with low vision. More research is also needed to determine the effectiveness of low…
