Investigation of the relationship between a statistically determined severe discrepancy between expected and actual achievement levels and subsequent labeling of 733 students as learning disabled found only a slight majority of labeled students manifesting a severe discrepancy suggesting this criterion is inconsistently applied in making…

This article reviews the efforts made since 1962 to define learning disabilities, discusses 11 prominent definitions, identifies important conceptual elements on which the definitions differ, and calls for a consensual acceptance of the National Joint Committee on Learning Disabilities definition.

The paper develops the phonological-core variable difference model to conceptualize differences between dyslexic and other poor readers. The model highlights the importance of viewing the concept of dyslexia as the outcome of the application of an arbitrary criterion in a continuous distribution. (Author/DB)

Assessment batteries of 200 elementary children with learning disabilities were analyzed to identify practices associated with the use of individual intelligence and achievement tests. Among conclusions: Many students identified as SLD have below-average intelligence, do not exhibit discrepancies on the Wechsler scale, and do not have severe…

In response to Gresham and Elliott (1989), who concluded that a social skills deficit should not constitute a learning disability, this paper claims that current definitions allow for including social skills deficits. They propose limiting the definition of learning disabilities to intentional learning contexts, thus excluding social skills…

This critique of a paper by Linda Siegel (EC221505) challenges Siegel's assumptions on the relationship of Intelligence Quotient to learning disabilities as being unacceptable and non-literature-based, and points out that discussion of Intelligence Quotient cutoffs may be moot given that 49 states employ no cutoff for learning disabilities.

The study with over 2,500 children (ages 9-14) found the two approaches identified somewhat different groups of children as reading disabled despite little difference in performance on the Halstead-Reitan Neuropsychological Battery for Children. (Author/DB)

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…

Use of the discrepancy approach in defining learning disabilities is challenged, as intelligence tests do not measure potential, are not independent from what is measured by achievement tests, and are not powerful predictors of low reading performance. Use of intelligence tests in analysis, identification, and definition of learning disabilities…

In commenting on Linda Siegel's argument (in EC221505) that Intelligence Quotient is not causally related to reading difficulties, this paper argues that Intelligence Quotient is relevant to the definition of reading disabilities but that present knowledge may not justify its use in the selection of children for special services.

The response to previous articles on the Regular Education Initiative looks at the definition of learning disabilities, identification, mainstreaming of mildly handicapped students, attitudes of general educators toward high risk students, the importance of prevention at the elementary level, and delivery systems.

This paper describes the definitions, diagnostic criteria, and eligibility criteria used by vocational rehabilitation agencies in serving adults with learning disabilities. The paper emphasizes that the focus of all vocational rehabilitation services is on employment and that counseling is at the core of the service program for persons with…

This article introduces four papers (and responses to them) originally given at an April 1990 conference on the identification and treatment of dyslexia. Noted is the lack of consensus on what dyslexia is, how the condition comes to be, and what the nature of educational intervention ought to be, though developmental views are seen to predominate.…

Data from the Connecticut Longitudinal Study were used to compare two definitions of reading disability: a discrepancy-based model and a low reading achievement model. Children (n=415) satisfying each definition in second grade were compared retrospectively in kindergarten and prospectively in fifth guide. Findings suggest more similarities than…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…
