A study was conducted of 10 bilingual (English/Spanish) and 10 monolingual English elementary school students with visual impairments to determine any differences in their knowledge of basic concepts. No significant differences were found. There was a correlation between vision levels and scores on a tactile test of basic concepts. (CR)

As follow up to a study which compared forced-choice preferential looking (FPL) with pattern visual evoked potential (VEP), this study increased the VEP success rate and improved agreement between the FPL and VEP acuity estimates by using horizontal bar stimuli for young preverbal children (n=17) with nystagmus.

The present study was designed to examine the effectiveness of Fatal Vision Goggles in reducing intentions to drink and drive. Participants performed a field sobriety task and drove in a traffic simulator while wearing the goggles. A regression analysis was performed in order to predict changes in intentions to drink and drive, using typical…

Two studies examined how adolescents with low vision perceive their ability to drive. The results of both studies indicated similarities in the participants' responses with respect to knowledge of visual impairment, information about options for driving with low vision, frustrations and obstacles imposed by not being able to drive, and independent…

Vision screening appears to be particularly important for adult education (AE) programs. Although expected failure rates for school-age population vision screenings are 15 percent, vision screenings of AE clients have yielded dramatically higher failure rates. Vision screenings of 106 Illinois AE students have shown that 66 percent had one or more…

In order to provide needed optometric services to partially sighted individuals and to alleviate a critical manpower shortage, trained paraprofessional assistants should be part of the low vision clinic team. (Author/LH)

Perceptual-motor functioning is a cyclic process involving: (1) organizing incoming sensory stimuli with past or stored perceptual information; (2) making motor (internal) decisions based on the combination of sensory (present) and perceptual (past) information; (3) executing the actual movement (observable act) itself; and (4) evaluating the act…

Visual acuity as a function of target position and density was measured in a letter recognition task. A homogeneous pattern of equally-spaced elements was tachistoscopically exposed, where the target was never located at the boundaries of the pattern. The target was marked with a spatial cue to control attentional processes. With such a spatial…

SIGNIFICANT RESEARCH ON THE PHYSIOLOGICAL AND FUNCTIONAL ASPECTS OF VISION AND READING DISABILITY IS SURVEYED. CONCLUSIONS BASED ON THE LITERATURE IN THE FIELD ARE DISCUSSED. A BIBLIOGRAPHY OF 70 REFERENCES AND A GLOSSARY OF TERMS ARE APPENDED. A TABLE SUMMARIZING REFRACTIVE ERRORS AND EYE DEFECTS CONTRIBUTING TO READING DISABILITY IS INCLUDED.…

Although several vision screening techniques are available for infants, none is routinely used. Visual deficits are often first detected through required preschool vision screenings, which vary in their comprehensiveness. No standardization for testing or administration exists. Some of the testing procedures used may have inappropriately high…

Explored the relationships among visual and auditory perception, academic aptitude, sex, and school achievement. Results indicate visual perception added significantly to prediction of achievement beyond that available through knowledge of a participant's sex and academic aptitude. (Author)

This study found that, of 18 children with severe visual and multiple impairments assessed using the Acuity Card Procedure (originally developed for assessing the visual acuity of infants), 42 percent responded. A similar group received a simple instructional intervention prior to testing and that group's response rate was 85 percent. (Author/DB)

A vision screening program established at a facility for 271 individuals with severe or profound mental retardation used the acuity card procedure as its measure. The procedure was found to be a valid and reliable screening tool for this population. A few residents had good visual acuities, whereas the acuities of others were poor. (JDD)

Lists strategies for promoting functional vision use in children with visual and motor impairments, including providing postural stability, presenting visual attention tasks when energy level is the highest, using a slanted work surface, placing target items in varied locations within reach, and determining the most effective visual adaptations.…

A study examined associations between bilateral visual acuity and depression among 391 Cuban Americans, 1,514 Mexican Americans, and 527 Puerto Ricans. Among Mexicans, depression was higher for those with moderate and greater impairment. Among Cubans, depression was higher for those with a distance visual acuity worse than 20/50. (Contains…
