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.

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…

These concluding comments on the series of articles introduced by Linda Siegel's paper (EC221505) summarize the bases for disputing the utility of intelligence tests. The learning disabilities field's resistance to abandoning use of Intelligence Quotient tests is also acknowledged, and improved assessment measures and further research are called…

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…

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…

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,…

Position statements of the Council for Learning Disabilities oppose the following: (1) use of discrepancy formulas in the identification of learning disabled individuals; (2) inclusion of nonhandicapped low achievers and underachievers in learning disability programs; and (3) measurement and training of perceptual and perceptual-motor functions.…

This article asserts that the learning disabilities field must (1) address causality in differentiating learning disabilities from other learning problems, (2) expand prevailing approaches to individualizing instruction so that intrinsic motivation is accounted for in a systematic, comprehensive manner, and (3) move beyond piecemeal programs to…

Factors that may explain the increase in the prevalence of learning disabilities are explained. One factor is related to the newness of learning disabilities as a discipline, and one is related to social/cultural changes (such as substance abuse, poverty, and lack of social support) that have occurred in U.S. society. (JDD)

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 response to Coles (EC 220 146), the author notes issues concerning: who is labeled "learning disabled," why they are labeled, how they are helped, how the solutions have become the problem, what real learning is, how to use present resources to transform the system, and the contribution of a collaborative ecological approach.

This commentary supports Linda Siegel's challenge to the learning disabilities field (in EC221505) to produce data indicating that dyslexic readers differ from other poor readers in their cognitive processing, educational prognosis, and response to treatment. The commentary also points out that the existence of Matthew effects reinforces Siegel's…

In response to Larry Silver (EC 231 774) concerning whether attention deficit-hyperactivity disorder is a learning disability via a related disorder, this article proposes an interactional perspective that stresses the educational needs of the child within his/her total environmental context. It also summarizes the current empirical and clinical…
