Background: The Learning Disability Screening Questionnaire (LDSQ) has been shown to have high sensitivity and specificity to identify those who are likely to meet intellectual disability diagnostic criteria (McKenzie, et al. [McKenzie K., 2015]). However, there is no independent research to date to support these findings. Materials and Methods:…

We review the evolution of the conceptualisation of dyslexia and along with it the current, 21st century definition of dyslexia. Our starting point is the seminal report by Pringle Morgan in 1896, followed by early 20th century reports by Hinshelwood, and continuing with concepts of brain injury and minimal brain dysfunctions then to the emergence…

Dyslexia and other learning disabilities are not being properly recognized and treated in our educational system or society at large. Unrecognized and untreated learning disabilities represent a serious social and economic problem, not only to the individual but to society as a whole. For example, antisocial behavior, as seen in prison populations…

This study surveyed a national sample of school psychologists with respect to the identification of reading disabilities (RD). It covers school psychologists' opinions regarding perceived benefits of the use of cognitive assessment in RD identification, both within and outside of an IQ-achievement discrepancy model. The survey also solicited…

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…

The relationship between language disorders, learning disabilities, verbal and performance IQ discrepancies and six tests frequently used in screening language disordered children was examined with 95 students in grades 4-12 classified as learning disabled and/or language disabled. Ss were divided into three groups based on profiles from the…

Five formulas for identifying discrepancies for eligibility as learning disabled (LD) were applied to 137 children (ages 6-14) already diagnosed as LD. Among results cited was that 64 percent were not identified as LD by any formula. Issues concerning the use of discrepancy formulas for LD screening are discussed. (Author/JW)

Analyzed the reliability, abnormality, and validity of Verbal Performance discrepancy scores on the WISC-R in relation to clinical decision making about learning disabilities. Suggests the information of greatest value seems to be the magnitude of the discrepancy that is both reliable and valid for learning-disabled children. (Author)
