One hundred kindergarten children completed a phoneme segmentation test, an invented spelling test, and two tests of visual-motor ability. Scores on both tests of phoneme awareness predicted between 30% and 40% of variance in reading ability a year later, while visual-motor scores bore a less substantial relationship to future reading ability.…

This study involving 30 college students with learning disabilities and 30 students without learning disabilities (ages 18-30) compared results obtained on the Wechsler Adult Intelligence Scale-Revised and the Kaufman Adolescent and Adult Intelligence Test. Results found no significant differences between the two groups or between tests.…

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

The validity of Scholastic Aptitude Test (SAT) Verbal-Mathematical discrepancies as indicators of college learning disability (LD) was assessed for four groups of LD students (Total N about 5000) taking different test formats. Comparison with non-LD student scores indicated no evidence of larger discrepancies for the LD groups. (Author/DB)

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)

A study examined the efficacy of the Restricted Academic Task in evaluating the effects of stimulant medication in 149 children (ages 5-17) with attention deficit hyperactivity disorder. The measure consists of standardized observation of a child performing an academic-like task, and was found to be both reliable and valid. (Author/CR)
