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…

Because of the increasing use of color in instructional materials at the level of the primary grades, the Health Service Department of the Denver Public Schools became interested in investigating the color vision of 5- and 6-year-olds. A project was established to create color-vision testing methods and to use those methods to ascertain incidence…

Vision is a complex process involving three phases: physical (acuity), physiological (integrative), and psychological (perceptual). Although these phases cannot be considered discrete, they provide the basis for the visual screening procedure used by the Reading Services of Colorado State University and described in this document. Ten tests are…

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…

Discusses the shortcomings of the Snellen eye chart as a vision screeing test and proposes the use of a newer test--the Modified Telebinocular Technique. (MTT)

Auditory and visual recognition were studied in subjects ranging in age from 10 to 60 years. In comparison with perceptual and response factors, memory scanning time is relatively insensitive to age differences, and auditory recognition involves the use of a pre-linguistic memory system insensitive to age differences.

Discusses issues related to possible health hazards associated with viewing video display terminals. Includes some findings of the 1979 NIOSH report on Potential Hazards of Video Display Terminals indicating level of radiation emitted is low and providing recommendations related to glare and back pain/muscular fatigue problems. (JN)

The role of optometry in the study of learning difficulties and the problems of interpreting research results in the fields of optometry and ophthalmology are discussed. Limitations of school visual screening are described, and it is suggested that many children with learning difficulties should be referred for a full clinical visual examination.…

All children have intelligence in varying degrees in various abilities; Structure of Intellect (SOI) Institute tests diagnose those abilities successfully in gifted, deaf, retarded, aphasic and all ethnic groups. With a database of thousands of student test responses, materials are developed to prepare children for the future. (NEC)

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)

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)
