This longitudinal study assessed (a) whether performance changes in working memory (WM) as a function of dynamic testing were related to growth in reading comprehension and (b) whether WM performance among subgroups of children with reading disabilities (RD; children with RD only, children with both reading and arithmetic deficits, and low verbal…

This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the…

A study investigated whether higher prevalence of reading disabilities among boys is related to gender bias in the prediction of reading from IQ. Data from 1,139 New Zealand children (collected during ages 5-13) indicate a significant intercept bias. Boys' predicted reading scores were systematically overestimated, thereby inflating IQ-reading…

Psychoeducational assessment variables for 119 referred high-school students were subjected to discriminant function analysis. Variables predictive of learning-disability classification were spelling, intelligence quotient, and the interview question, "Do you think going into a special class/program would help you?." (MSE)

Two classification procedures for identifying children with reading disabilities were compared, differing in their use of intelligence quotient (IQ). Results indicated that abandoning IQ in classification had a very limited impact on the number of children identified as reading disordered, but that use of IQ resulted in more high-IQ children being…

This article discusses research on the traditional use of the IQ-achievement discrepancy to define specific reading disability. It highlights results from a study which found that IQ scores did not differentiate between poor readers who were found to be readily remediated and poor readers who were difficult to remediate. (Contains references.)…

This response to a paper by Linda Siegel (EC221505) on the relationship between Intelligence Quotient and learning disabilities addresses the differences between classification and identification, limitations in Siegel's conceptualization of intelligence, and the representation of the language and learning domains subsumed within the learning…

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,…

This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

This study of 1,657 children (ages 7-16) found that although children with dyslexia had higher intelligence quotient scores than poor readers, the 2 groups did not differ in performance on reading, spelling, phonological processing, or most language and memory tasks. The performance of both reading-disabled groups was significantly below that of…
