Learning disorders can have adverse impacts on children and families extending beyond the academic skills deficits. The goal of the present study was to assess the impact of the school's response, following an independent evaluation, for child and family school-related quality of life (QOL). We hypothesized that a positive school response would be…

Increasing evidence suggests that children with developmental dyslexia exhibit a deficit not only at the segmental level of phonological processing but also, by extension, at the suprasegmental level. However, it remains unclear whether such a suprasegmental phonological processing deficit is due to a difficulty in processing acoustic cues of…

Several studies have reported high comorbidity for reading disability (RD) and psychiatric disorders. The aim of this study was to investigate the comorbidity of subthreshold and full psychiatric disorders with RD while comparing subgroups based on age of RD recognition (early vs. late). We analyzed data from 130 children with RD and 82 typically…

Research involving monolinguals has demonstrated that language impairment can be noticed in the early years and tends to persist into adolescence. More recently, research has begun to address the challenges of identifying and treating Developmental Language Disorders (DLD) in English Language Learners (ELLs). Developmental patterns of DLD are not…

A relationship between motor and mathematical skills has been shown by previous research. However, the question of whether subtypes can be differentiated within developmental coordination disorder (DCD) and/or mathematical learning disability (MLD) remains unresolved. In a sample of children with and without DCD and/or MLD, a data-driven…

Response-to-intervention (RTI) approaches to disability identification are meant to put an end to the so-called wait-to-fail requirement associated with IQ discrepancy. However, in an unfortunate irony, there is a group of children who wait to fail in RTI frameworks. That is, they must fail both general classroom instruction (Tier 1) and…

This study investigated the incidence of learning disabilities in 105 children (ages 6-18) with neurofibromatosis Type 1 (NF-1). Results found that nearly 70% of the subjects were academically deficient and 42% met the criteria for learning disabilities. A low incidence of visuospatial-constructional deficits was also found.

An assessment of foundation processes was administered to 51 Scottish children with reading difficulties and to 56 reading-level-matched controls. Results suggested the foundation is in place by the reading age of 7 years and that foundation-level dyslexia is identifiable in children with reading difficulty whose reading ages fall below this…

A study examined the stability over 19 months of academic subtyping classification of 80 children (ages 9 to 13) representing four subtypes of arithmetic disabilities (AD). Approximately half of the sample retained AD regardless of identification method. Children with deficits in arithmetic, reading, and spelling disabilities exhibited the…

Three studies investigated the effectiveness of the Computer Assisted Reading Diagnosis, a diagnostic system based on "rauding" theory (a collection of theories, constructs, and equations developed to describe, explain, predict and control the ability to comprehend relatively easy sentences) and a causal model of reading achievement.…

This article argues that the regression-based discrepancy method used in the diagnosis of learning disabilities is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It is mathematically demonstrated that the regression-based discrepancy method largely reflects…

This article evaluates conclusions in Van den Broeck's article (2002) that argue the regression-based discrepancy method (RDM) used in learning disabilities diagnosis is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It concludes acceptable models support the…

This article responds to a critique by Willson and Reynolds (2002) that argued for the use of the regression-based discrepancy method (RDM) for identifying learning disabilities. It argues the statistical and theoretical counterarguments are based on a misreading of the statistical models presented. (Contains 8 references.) (Author/CR)

Composite reading performance data from 223 pairs of identical twins and 169 same-gender fraternal twins in which at least one member was classified with reading disability were subjected to multiple regression analysis. Results indicated that the genetic etiology of reading disability differs as a linear function of IQ. (Contains extensive…
