The study reported here investigated the quality and content of visually impaired and sighted children's descriptions of two routes around their schools from memory and by using a map (print or tactile). It found that the descriptions from maps were generally poorer than those from memory, the descriptions of the visually impaired children contained more information than and were qualitatively different from those of the sighted children, and the descriptions of the younger visually impaired children were less well specified than those of the older visually impaired children and the sighted children.

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.
