Presented are a rebuttal and a counter-rebuttal to an earlier article questioning the educational usefulness of perceptual tests with learning disabled children. (DB)

The investigation, which involved 55 learning disabled and 54 normal children (mean age seven years), was designed to test the hypothesis that differences between these groups on tests of perceptual functioning are not educationally significant. (Author/SBH)

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)

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)

The study examined the process by which diagnostic data on children thought to have learning disabilities (LD) are generated and used. Emphasis was placed on the validity of test instruments in common use in the field. Since part of the practical validity of any instrument used to identify an LD child rests on the validity of the LD construct…
