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)

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)

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)

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)
