This article presents the results of statistical analyses of the scores on subtests of the Intelligence Test for Visually Impaired Children—a new test with nonverbal subtests for children aged 6–15. The analyses were conducted for two vision groups: children with no usable vision and children with usable vision. The classification is based on the results of a short, objective vision test. The results suggest that the battery has differential—factorial and predictive—validity.

Describes an investigation of how different figure-ground contrast combinations affect the visual functioning of visually impaired children. 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. Eighteen visually impaired children ranging in age from nine years, four months to 14 years, six months participated in this study. The findings indicated that neither reversals in contrast nor chromaticity differences were effective measures for increasing visual functioning.

In the authors’ previous study, the success rate for forced-choice preferential looking (FPL) with preverbal visually impaired children was higher than that with pattern visual evoked potential (VEP). The current study sought to increase the VEP success rate and to improve agreement between the FPL and the VEP acuity estimates using horizontal-bar stimuli for children with nystagmus and steady-state presentation for those without nystagmus.
