The aim of our study was to describe specific psychological resources of adults with developmental dyslexia and compare them with psychological resources of adults without developmental dyslexia. Potential differences were analyzed in visual-spatial, creative, and motivational abilities. No evidence was found for either creative, or visuospatial…

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental…

Eleven adults who had been diagnosed as dyslexic in childhood were evaluated via psychological and educational testing and interviews. Reading and spelling deficits were marked, and patterns of skill weaknesses and cognitive abilities were found to have remained remarkably consistent over the approximately 17-year period. (CL)

The effects of grade level, achievement level, and sex were studied in the examination of determinants of visual-motor coordination and visual-perceptual reasoning in elementary school children. (KW)

Comparison of 24 elementary school-age children with attention deficit hyperactivity disorder (ADHD) and 20 children with attention deficit disorder without hyperactivity (ADD/noH) on a comprehensive neuropsychological assessment found math achievement test scores for students with ADD/noH were significantly lower than those for students with…

Learning quotients (LQ-ratio of actual to expected achievement) were computed for second, fourth, sixth, and eighth graders. Results indicated that the LQ was not statistically stable across tests, grade level, gender, or ethnicity. (CL)

This commentary re-examines Linda Siegel's four basic assumptions (in EC221505) inherent in the Intelligence Quotient-achievement discrepancy commonly used to define learning disability. The commentary also discusses the uses of alternative measures of intelligence and the role of Intelligence Quotient in the identification of learning-disabled…

This study compares algebra performance tested under timed and extended-time conditions of 88 community college students with and without learning disabilities (LD). With extended time, the LD students' performance did not differ significantly from the timed or extended-time scores of the students without learning disabilities. (Author/DB)

Issues raised in responses to Linda Siegel's paper (EC221505) on the relationship between intelligence test scores and learning disabilities are addressed. Discussed are the nature of intelligence, classification of learning disabilities by discrepancy between intelligence test scores and achievement scores, the existence of learning disabilities,…

Four groups of 7- to 10-year-old girls (N=37), who were either (1) hyperactive, (2) reading disabled, (3) hyperactive and reading disabled, or (4) solely attention disordered, were contrasted with male counterparts on measures of intelligence, achievement, personality, and cognitive style. Among findings were significant sex differences across…
