Disfunctions are drawn between visual perception and visual function, and four optometrists respond with further analysis of the visual perception-visual function controversy and its implications for children with learning problems. (CL)

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)

In order to evaluate the effectiveness of the Wechsler Intelligence Scale for Children (WISC) in discriminating auditory or visual deficits, 121 learning disabled children (mean age 100 months) were tested. (PHR)

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. (Author)

Performances on the Bender Visual Motor Gestalt Test and on a visual discrimination task using the same forms were found not to be related. Implication for identification of perceptual deficiencies and subsequent perceptual training are discussed. (KW)

The paper suggests that the use of a single visual-motor test, (here, the Winter Haven Perceptual Forms Test) as a screening device for visual-motor difficulties in the first grade is questionable. (Author)

Evaluation of the Frostig Developmental Test of Visual Perception found that it measured a single general factor of perceptual organization which was weakly related to IQ and unrelated to reading ability. (KW)
