Unlike other special education categories defined in U.S. law (Individuals with Disabilities Education Act), the definition of specific learning disability (SLD) has not changed since first proposed in 1968. Thus, although the operational definition of SLD has responded to new knowledge and understanding about the construct, the formal definition…

The reauthorized Individuals with Disabilities Education Improvement Act (IDEA) established new provisions for specific learning disability (SLD) identification, including: (a) no longer requiring consideration of IQ-achievement discrepancy and (b) permitting response to intervention (RTI) as part of SLD evaluation procedures. We discuss several…

The policies underlying the specific learning disability (SLD) regulations in the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA) are analyzed. The analysis focuses on the Response-to-Intervention (RTI) provision ("if the child responds to scientific, research-based intervention") as a diagnostic model,…

In rebuttal to a critique of a previous paper, the authors stress the complexities of defining the term "learning disabilities" and the inadequacies of Kosc's approach to a prior definition based upon established definitions of "learning" and "disability" (Author/DB)

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. I argue that there are many questions about RTI that remain unanswered, and radical changes in proposed regulations are not warranted at this time. Many fundamental issues related to RTI…

Meta-analysis was used to arrive at a quantitative synthesis of the results of 94 studies of the validity of Wechsler regroupings for differential diagnosis of learning disabilities. The primary findings indicated that no recategorization, profile, factor cluster, or pattern showed a significant difference between learning disabled and normal…

The paper describes learning disabled children as disassociated learners (not actively involved in the learning process). The framework shows how it may be logically conceptualized that some children disassociate themselves from academic learning and come to be termed learning disabled. (Author/CL)

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. We argue that many questions about RTI remain unanswered, and that radical changes in the proposed regulations are not warranted at this time. Since many fundamental issues related to…

In attempting to explain definitional problems in the field of learning disabilities, the authors review concepts from the history and philosophy of science. It is concluded that learning disability is a victim of its own history, and a breaking from the past is necessary for the definitional problem to move closer to resolution. (Author/CL)

The paper reviews research of A. Strauss and H. Werner on behavioral differences between exogeneous (brain injured) and endogeneous (familial-cultural) mental retardation using quantitative methods of research synthesis. Findings offer little empirical support for the presumed behavioral differences and reveal considerable overlap among the…

This response to Stanovich's (EC 607 092) proposal of a new type of learning disability, dysrationalia, looks at implications for the entire learning disabilities field, especially increasing differences between operational and substantive definitions and the ongoing creation of new types of learning disabilities to overcome perceived definitional…

The article reviews theoretical issues surrounding the concept of severe discrepancy in the diagnosis of learning disabilities. Components of discrepancy, including ability measures and achievement measures, are discussed. It is concluded that discrepancy is a necessary but not sufficient criterion in the identification of a learning disability.…

Critically evaluates recent research aimed at empirical identification of homogeneous subtypes of learning disability. It is suggested that researchers strive for more commonality in the methods and measures used for subtype analysis leading to a single classification scheme to reduce heterogeneity and improve educational efforts. (Author/DB)

Intended for teachers, the article provides an introduction to the four major classes of psychotropic medication (stimulants, tranquilizers, anticonvulsants, and antidepressants) commonly prescribed for children with learning or behavioral disorders. Specific effects on the classroom are addressed. (DB)

A case is presented to reveal the existence of a relationship between learning disabilities and cultural-economic disadvantage. Evidence from a variety of sources is presented suggesting that the problem is most properly viewed as a complex interrelationship among the phenomena of learning disabilities, brain dysfunction, and cultural-economic…
