The span of apprehension (a measure of the amount of information processed simultaneously from a brief visual display) was studied in two experiments involving 40 normal and learning disabled boys (ages 6-11 years). (Author/DLS)

Scores of 25 learning disabled students (aged 9 to 13) were compared on five tests: a visual-perceptual test (Coloured Progressive Matrices); an auditory-perceptual test (Auditory Motor Placement); a listening and reading comprehension test (Durrell Listening-Reading Series); and a word recognition test (Word Recognition subtest, Diagnostic…

Investigated with 64 upper middle class first-grade children of normal intelligence and visual perception was the construct validity of the trait of visual figure-ground perception. (Author/DB)

Forty-three elementary students with learning disabilities in mathematics were administered a variety of measures to examine the relationship between selected language and visuospatial skills and mathematic achievement. (Author/DLS)

The investigation attempted to determine first, the correlations among the Frostig Developmental Test of Visual Perception, the Bender Visual-Motor Gestalt Test, and an experimental Visual Discrimination Test of Words and second, the visual perceptual factors that emerged when the data were treated factorially.

The investigation of the perceptual integrative abilities of 6 to 9-year-old language delayed children with nonspecific etiologies showed them to vary from normal controls in auditory-visual integrative ability and perception of distorted speech, but not in visual-motor integrative behavior. (KW)

Cited is research which indicates that ocular motor abnormalities in children with reading difficulties are factors in the processing of visual information. (CL)

In the article the author refutes J. Fletcher and P. Satz's analysis of the etiology of reading disability on logical, theoretical, and empirical grounds. (Author/PHR)

In the rejoinder the authors describe the methodological and interpretive factors in the Vellutino et al, experiments which limited the degree to which the studies refuted perceptual deficit hypotheses of reading disability. Note: for more of the interchange see EC 114 687-688. (Author/PHR)

Examined was the relationship between the Frostig Developmental Test of Visual Perception and academic achievement as measured by the scholastic Research Association Achievement Test Battery with 125 primary grade children. (Author/DB)

The effects of visual paradigmatic organization on verbal recall among language/learning disabled children was studied with 20 such children (age: 8-13 years), who were screened to eliminate visual memory deficits. (Author)
