The author contends that the current evidence for an attentional deficit explanation of learning disability must be evaluated cautiously. (Author/CL)

Problems with the current definition of learning disabilities (LD) include its misinterpretation, failure to recognize the developmental nature of LD, and lack of statement about etiology. The definition offered by the National Joint Committee on Learning Disabilities is presented. (CL)

The paper summarizes several approaches to the identification of learning disability and then discusses the nature of learning disability in the context of competing hypotheses as possible explanations of insufficient or unsatisfactory achievement. Because learning disability may only be inferred as a cause of unsatisfactory learning, the…

Fundamental assumptions concerning the cause of learning disabilities are described and criticized. At a broader level, research and theory in three different paradigms are discussed: (1) neuropsychological; (2) information processing; and (3) applied behavior analysis. Four recommendations for future progress in the conceptualization and…

The discussion of the history of learning disabilities, emphasizes the lack of a precise definition and the ambiguous nature of etiological duration, and incidence explanations. He asserts that the teacher-therapist must become the major focus of study and research. (CL)

The author draws on his experience with learning disabilities (LD) to offer 10 challenges to the profession, including to adopt a historically and professionally honest and accurate definition of LD, to recognize two separate groups within LD, and to advocate against the principle of least restrictive environment. (CL)

Opposing views regarding the connection between lead exposure and cognitive impairment are presented. C. B. Ernhart states that no study has yet proved that low-level lead exposure is detrimental to child development, while H. L. Needleman asserts that previous research studies have proven conclusively that such a connection exists. (CB)

The paper identifies areas of agreement among leaders in learning disabilities (LD) including heterogeneity of the LD population; explores the classification problem as it relates to etiology and/or treatment, and proposes a five-step plan to influence public policy concerned with differentiation and treatment of different types of learning…

This article introduces a special issue on the double-deficit hypothesis for dyslexic readers' failure to acquire adequate word recognition skills. This theory suggests that dyslexic readers have a deficit in naming speed in addition to the more widely recognized deficit in phonological decoding skill. (Contains references.) (DB)

The paper sets forth the position of the National Joint Committee on Learning Disabilities regarding definitions of learning disabilities (LD) as found in P.L. 94-142, the Education for All Handicapped Children Act. The paper cites difficulties with the current definition, suggesting that misinterpretation has given the impression that individuals…

This article presents a reinterpretation of Gerald Coles's 1987 book "The Learning Mystique," viewing it as making a positive contribution to the learning disabilities field in both practical and theoretical ways, by offering the possibility of different treatment options and expanding the intellectual base for researchers. Potential research…

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…

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…

In response to Coles (EC 220 146), the article examines evidence of the roles of intrinsic biological characteristics and the environment in learning disability and suggests that learning disability is a biological susceptibility manifested in an environment promoting its expression. (DB)

In response to Coles (EC 220 146) the author outlines points of agreement and identifies points of divergence including Coles' confusion of ordinary poor reading with true dyslexia, the role of phonological processes, and philosophy of science issues concerning Coles' alternative interactivity theory.
