The purpose of the investigation described in this article was to revise Hill's test for assessing the development of spatial concepts among visually impaired children, “Concepts Involved in Body Position and Space,” establish the test's validity and reliability, and collect normative data. Orientation and mobility specialists administered the revised instrument to 273 visually impaired children ages 6 through 10 from 48 different educational programs in 23 states. Normative data were then collected in the form of percentiles by age; percentage passing each item by age and by reading modes; and indexes for the difficulty and discriminatory power of each item as well as the proportion of correct answers. According to the results, the revised instrument is valid and reliable enough to use with visually impaired children in the age groups studied.

Visually Impaired Children

The present study addresses the main problems of blind and visually impaired children's education in relation to their motor-development problems and the ways that they can be solved. We have tried to identify factors that produce motor-development differences between them and normal children; define educational strategies that contribute best to their motor development; and investigate methodically the problem considered by Warren (1977)—the heterogeneity of blind and visually impaired children's samples—through design and multivariate analysis. We evaluated balance and spatial concepts using Leonard and Hill's test. We used a stimulative program and compared the blind and visually impaired children's performances to the visually normal children's performances.

Visually Impaired Children

Visually impaired children have difficulty acquiring spatial orientation concepts necessary for proficient locomotive movements and independent mobility. The majority of past research on remedying spatial deficits has focused on older visually impaired individuals. It is the purpose of this paper to advocate the development of movement programs for preschool visually impaired children in order to compensate for their orientation deficits. Skills necessary for acquisition of spatial concepts should be taught through movement programs at an early age in the normal developmental sequence instead of attempting to remedy deficits at a later age.

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.

Visual Evoked

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.
