This paper urges a deeper consideration of the role of psychometrically defined intelligence in the operationalization of aptitude/achievement discrepancies inherent in most definitions of learning disability. It proposes a new disability, dysrationalia, the inability to think and behave rationally despite adequate intelligence. (DB)

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…

Some of the issues that dominated, or at least held sway, in the neuropsychology of learning disabilities (LD) in the 1970s included: the definition of LD, whether there are reliable and valid subtypes of LD, whether and to what extent LD are related to cerebral dysfunction, and whether LD are related to types and/or degrees of psychosocial…

School psychologists in North America are facing a transformation of their professional practices brought about by impending changes in operational definitions of learning disabilities (LD). This multimethod study explores the learning disabilities-related beliefs and practices of school psychologists in Western Australia, where these changes have…

Learning disabilities (LD) has been recognized as a category of special education in Taiwanese law since 1984, and policies ensure educational services for children and youth who have LD. The official definition and identification criteria established in Taiwan's laws closely correspond with those of the United States, but practice differs,…

The report examines current problems in assessing and identifying learning disabled students and recommends practices to solve those problems. An initial chapter reviews the reasons for misidentification of this population. Section I presents a summary of identification practices drawn from guidelines of 50 state educational agencies, the District…

The various theoretical orientations toward the etiology of dyslexia are evaluated and implications for future research are discussed. (CH)

Designed by the Bloomfield Hills (Michigan) multidisciplinary evaluation team, the document suggests procedures and enabling activities to implement the assessment and identification of learning disabled students. Individual sections address five areas (ability, achievement, severe discrepancy, exclusionary clause, and need for special education…

Three investigations examined the effects of IQ and chronological age (CA) on the calculation of severe discrepancy levels of 102 hypothetical and 125 actual severely learning disabled students (5 to 17 years old). Results indicated that IQ was highly influential on obtained severe discrepancy levels (SDLs) and related percentage discrepancies;…

This dictionary was compiled to serve teachers in the fields of reading and learning disabilities. The entries are alphabetized and include terms from related disciplines; measurement, evaluation, and statistics; linguistics; library science; psychology and learning; education; and medicine, particularly dealing with vision, sensory, and motor…

An operational index of discrepancy between ability and achievement using the Wechsler Intelligence Scale for Children and the Peabody Individual Achievement Test (PIAT) was tested with 50 male and 10 female legally identified learning disabled (LD) children (mean age 9 years 2 months). Use of the index identified 74% of the males and 30% of the…

Attaching diagnostic labels to learning disabled children can add to their difficulties. (Author/SBH)

This paper reviews the implications of definitions of learning disabilities for the Regular Education Initiative. Since heterogeneity (i.e., developmental imbalances, intraindividual gaps) is characteristic of this population, regular classroom modifications alone are unlikely to meet these students' needs and thus special services will continue…

This paper reviews research on the classification of students with learning disability (LD). It first examines the evolution of LD definitions and the evidence for three components of LD classification: discrepancy, heterogeneity, and exclusion. It suggests that classification hypotheses involving discrepancy and exclusion have weak validity and…

The author responds to an article (EC 151 569) questioning the federal definition of learning disabilities (LD) because federally funded child service demonstration centers did not adhere to it. He asserts that this argument is faulty and that LD can be defined. (CL)
