Clear quantitative and qualitative differences in visual scanning strategies were found between the groups and discussed with respect to differences between perceptually impaired and normal children's rates of encoding information and reliance upon visual memory. (Author)

Reports conversations with children attending a New Zealand reading clinic that indicate that the maximum brightness contrast of black-on-white print was a strong contributing factor in the children's reading disabilities. (Author/GT)

Compared were the performances of 28 cerebral palsied, 19 mentally retarded, and 30 normal children between the ages of 8 and 16 years on measures of four components of visual perception: figure-ground relationships, form constancy, spatial position, and spatial relationships. The figure-ground component was tested tachistoscopically; the…

A study was conducted to determine the relationship between visual perception-visual motor deficits and reading achievement of remedial readers, and to analyze the performance of various subjects in the three classifications of perceptual dysfunction to determine if significant differences existed among them. Subjects were 102 remedial readers…

A study involving 120 second-grade students with deficiencies in visual perceptual skills was designed to determine the effects of a vision training program on reading test performance. Students receiving vision training did significantly better in tests measuring reading comprehension and word recognition skills than did students who did not…

Wechsler Intelligence Scale for Children-Revised (WISC-R) subtest scatter and Bannatyne recategorization scores were investigated with three types of learning disabilities in children 6 to 16 years old: visual-motor and visual-perceptual disability (N=66); auditory-perceptual and receptive language deficit (N=18); and memory deficit (N=12). Three…

Kaufman Assessment Battery for Children scores obtained by 20 Down's syndrome children (ages 8-12) were compared with scores of 20 younger siblings and 20 nonretarded children matched for mental age. Among results were that Down's syndrome children performed significantly better on subtests employing visual as opposed to auditory channels of…

Spatial and temporal matching abilities of normal and disabled readers were investigated. Average and dyseidetic readers were better able than dysphonetic and alexic readers to match purely temporal information. Dysphonetic and alexic readers demonstrated greater difficulty with temporal rather than spatial information. The existence of memory and…

Four experiments examined the spatial orientation of children who walked while wearing a blindfold. Children and adults viewed a target, were guided blindfolded to a new point, and then aimed a pointer at the target. Route complexity, but not number of targets or time delay, affected spatial orientation. Some age differences were observed. (BC)

Two experiments were conducted to assess the performance of freshmen chemistry students with poor spatial visualization skills. In the first experiment, 31 chemistry students with academically deficient backgrounds completed a diagnostic test of their ability to visualize and interpret pictorial representations of simple molecular structures. At…

Grade level norms were developed, based on a sample of 678 elementary school students, for various error scores of the Benton Visual Retention Test. Norms were also developed for 201 normal children, 58 minimal brain dysfunction children, and 101 educable mentally retarded children. In both the copying mode and the memory mode, most errors were…

Evaluated during an 8-week period were the effects of three instructional reading methods for 36 reading retarded students (grades 4-6) with differing degrees of visual function difficulties (perceptual impairment rather than visual acuity problems). Ss were divided into two groups according to their high or low degree of visual function…
