The study employed the use of field reversals--printing white and yellow foregrounds on a black background--to decrease the amount of light reflected from printed materials to the eye with 18 visually impaired children (9-14 years old). The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures…

Signs from lists used with mentally retarded and autistic children and previously rated for visual iconicity were presented tactilely to 13 blind adults. Visual and tactile ratings were very similar across blind and sighted groups, as were statements of relationship between signs and their meanings. (Author/CL)

An overview of psychophysical studies on visual factors that influence normal- and low-vision reading is presented. General principles, such as the presence or absence of central vision, were found to predict reading performance despite the heterogeneity of low-vision conditions. Results suggested most low-vision subjects meet the visual…

A model is proposed that organizes factors related to visual function into three dimensions: visual abilities, available resources and past experiences, and environmental cues. The model is explained to be useful in determining how to elicit visual behaviors or maximize visual function in persons with low vision. (Author/CL)

In three experiments, sighted college students tried to learn the names of the first 10 symbols of the braille alphabet. In Experiments 1 and 2, visual examination of the symbols enhanced learning. In Experiment 3, similar results were obtained when standard size braille symbols were used during the study trials. (Author)

The paper addresses the need to define terms used in vision training before successful programs can be formulated. Critical behaviors in three categories (visual attending, visual examining, and visually guided motor) are considered as are program alternatives focusing on visual environment management, visual skills training, and visually…

The article proposes helping visually handicapped clients make optimal use of remaining vision for travel in unmodified environments. Structured discovery learning exercises covering pattern recognition, depth perception, central acuity, and central field vision with peripheral field loss are offered. (Author/DB)

This article reports the first year results of a pilot study of 21 developmental milestones achieved by 82 visually impaired children in New York City. Some delays in visual-motor activities were found, as well as differences in the sequence of acquiring skills. Children with additional handicaps acquired milestones at a slower rate. (Author/DB)

This article discusses the increasing incidence of cortical visual impairments, resulting from medical advancements making possible the survival of critically ill children with severe brain damage. Discussed are the prevalence of multiple handicaps, formation of visual concepts, foreground/background distinction, potential for mainstreaming, use…

This study investigated the ability of color and motion to elicit and maintain visual attention in a sample of children with cortical visual impairment (CVI). It found that colorful and moving objects may be used to engage children with CVI, increase their motivation to use their residual vision, and promote visual learning.

This article reviews the theoretical and research literature on vision stimulation and vision training of children with severe irreversible visual impairments. It recommends early stimulation to prevent visual deprivation, use of operant conditioning, and the presentation of highly contrasting stimuli to stimulate visual awareness in children with…

Techniques for evaluating the multiply impaired child's functional level of vision are described and a sequence of visual stimulation instruction for children with visual impairments is presented. (PHR)

This article describes the High Vision Games, a habilitation model for youth with low vision which involves a pregame training phase; the games, where participants demonstrate their visual skills in high tech, low tech, or no tech versions; and postgame follow-through activities. The approach has had positive training, social, and professional…

Differences in how the two hemispheres of the brain handle spatial information were studied with blind subjects and blindfolded sighted subjects. The performances of all groups declined as the relative disorientation between the target and its duplicate increased, suggesting that visual imagery is not crucial to mental rotation. (Author/SEW)
