This article examines the problem of definition in learning disabilities. It discusses the failure of conceptual definitions to provide a clear idea of what learning disabilities are, examines the true nature of available definitions as stipulative definitions, and notes the difficulty in conceptualizing and implementing operational definitions.…

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…

The National Joint Committee for Learning Disabilities' definition of learning disabilities is presented, followed by a discussion of parameters to be considered in operationalizing the definition. Major definitional issues are then explored, including using testable and meaningful constructs, linking definitions to neuropsychological evidence,…

The manual examines issues in determining eligibility criteria for students with serious emotional disturbance (SED). Educational and clinical definitions of SED are compared, components of the educational definiton are examined, and the issue of differentiating behavioral disorders from serious emotional disturbance is considered. The assessment…

The manual is intended to present professionally defensible and generally agreed on criteria for the identification of students with behavior disorders in Iowa. Six major topic areas are examined in separate chapters: (1) overview of behavioral disorders in Iowa (historical background, assumptions underlying definition, desired use of definition…

To reduce Rhode Island's high percentage of students being classified as learning disabled, an advisory committee recommended development of a statewide Learning Disabilities Identification Process (L.D.I.D.), to prepare evaluation teams to consistently consider regulatory criteria and to justify their decisions when making learning disability…

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…

This article describes instruments and methods to assess the primary characteristics that define attention deficit disorder (ADD) for the purpose of identification. Issues in ADD assessment include identifying co-occurring disabilities, defining the severity of ADD, and determining the pervasiveness and situational nature of the behavioral…

The guide was intended for use by teachers of learning disabled students involved in assessment procedures. A philosophical framework, in which assessment is viewed in the ongoing team process, is followed by review of Wisconsin's rules on the identification of learning disabilities. A report format is presented as an outline for consolidating…

This guide focuses on identification and evaluation of students with behavior problems, emphasizing that identification of behavior problems is influenced by social values. The first chapter discusses the necessity for developing a definition of behavior problems from the educator's perspective, and outlines prevalence rates for behavior problems…

A survey of 51 state departments of education focused on learning disabilities definitions, identification criteria, and operationalization procedures. Results showed the continued impact of the 1977 federal definition and criteria. Findings are compared with those from a 1985 survey and discussed in terms of trends, prereferral interventions,…

This study of 1,657 children (ages 7-16) found that although children with dyslexia had higher intelligence quotient scores than poor readers, the 2 groups did not differ in performance on reading, spelling, phonological processing, or most language and memory tasks. The performance of both reading-disabled groups was significantly below that of…

This study of 640 twins with reading disability and 436 controls (mean age 12) examined external validity of the distinction between specific reading retardation and reading backwardness, in 3 domains: genetic etiology, sex ratio and clinical correlates, and neuropsychological profiles. There was no evidence of differential genetic etiology of the…

Two key concepts in diagnosing learning disabilities ("severe discrepancy" and "process dysfunction") are reviewed, and their relationship to the habilitation of learning is discussed. Guidelines are given for calculating a severe discrepancy, and the evaluation of processing skills is discussed. Strength models of remediation…
