Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane.

Many students have undiagnosed vision problems despite passing school vision screening. Traditional screening may miss problems with close vision, eye-hand coordination, and smooth eye coordination. The article discusses what teachers should look for, how to proceed if there is a problem, and how to create vision-friendly classrooms. A list of…

Qualitative follow-up was used to add depth to an econometrically based investigation of home and school predictors of achievement in Jamaica (Glewwe, Grosh, Jacoby, & Lockheed, 1995). In the original investigation, theory and research were used to identify potential predictors. Data on these factors, as well as student achievement, were…

The Vision In Preschoolers (VIP) Study, is a multi-phased, multi-center study designed to identify screening tests that best detect vision problems in preschool children. The VIP Study uses mobile medical units that are specially equipped to conduct vision screenings and eye examinations. Known as Vision Vans, these mobile units are staffed by lay…

The study evaluated the validity, reliability, and effectiveness in providing needed information of the Montana Functional Vision Assessment (MFVA) Instrument by comparing it with the Texas Education Agency Functional Vision Assessment and field testing the instrument in evaluations of nine multihandicapped students (ages 3-11). Evaluation led to…

A number of variables may affect the ability of students to perceive, and learn from, instructional materials. The objectives of the study presented here were to determine the projected color that provided the best visual acuity for the viewer, and the necessary minimum exposure time for achieving maximum visual acuity. Fifty…

The paper describes an approach to assessing the visual functioning of severely and/or profoundly impaired students. The assessment consists of three phases: identification, testing, and formal assessment. A checklist is used for identification. Testing considerations include medical factors (such as medications and effects of other handicaps),…

Test presentation mode significantly affected test performance in two randomized groups of college students exposed to audio/visual and visual test modes. A significant difference was found between test presentation mode and mean test scores; the audio/visual test mode was superior to the visual test mode; and the "brighter" students seemed to…

Reported were extensive statistical data on the prevalence of abnormal eye conditions found on examination, heterophoria test results, and history of eye problems as well as extent of interrelationship of the eye examination and vision test findings among children aged 6 to 11 years in the United States, based on findings from the Health…

THE RELATIONSHIP OF AUDITORY-VISUAL AND TACTUAL-VISUAL INTEGRATION TO INTELLIGENCE AND READING ACHIEVEMENT WAS INVESTIGATED. IN ADDITION, THE RELATIONSHIP OF THE TWO INTERSENSORY INTEGRATION TASKS TO EACH OTHER AND TO THE TYPE OF READING ERRORS MADE ON AN ORAL DIAGNOSTIC READING TEST WAS ALSO EXPLORED. THE SAMPLE WAS COMPOSED OF 121 WHITE…

Described is the Kirshner Saroj Visual Perception Speed Test (KSVPST), a measure of perceptual speed using pictures to identify children whose reading difficulties are due to visual processing deficiencies. It is explained that 323 children 6-13 years old were given the Keystone Visual Skills Test, the KSVPST, and reading readiness tests. Data are…

This study attempted to assess how very young children respond to discrepant social communications. Forty children, ages 12 to 42 months, with their mothers were exposed to four trial situations: two discrepant, two nondiscrepant communication episodes. Two observers recorded each child's movement and behavior. Results indicated a significant…

The study was designed to investigate the validity and reliability of the Motor-Free Visual Perception Test (MVPT) when used with 46 educable mentally retarded Ss (6-8 years old). (Author/SBH)

A screening program for vision problems and Usher's Syndrome (a common cause of deaf-blindness) among 210 hearing-impaired students found 44 percent had significant vision problems and 1 percent had Usher's Syndrome. The program involved an interagency network of school, health care, and support personnel and utilized a dilated ophathalmological…
