This study (a) examines the role of cognitive abilities, age and vocabulary in the development of definitions and (b) compares the development of definitions (in content and form) in children with and without Developmental Language Disorder (DLD). Definitions have been extensively studied in (non-)impaired populations. So far, no studies have…

Purpose: The current "specific language impairment" and "developmental language disorder" discussion might lead to important changes in how we refer to children with language disorders of unknown origin. The field has seen other changes in terminology. This article reviews many of these changes. Method: A literature review of…

This study outlines the literature relevant to the Cross-cultural issues and the politics of SEN and the different perspectives arising from the literature on this widely debated issue are addressed. In addition, the origin of the term "special educational needs" (SEN), its definitions and the types of special education needs are…

Five groups of children defined by presence or absence of syntactic deficits and autism spectrum disorders (ASD) took vocabulary tests and provided sentences, definitions, and word associations. Children with ASD who were free of syntactic deficits demonstrated age-appropriate word knowledge. Children with ASD plus concomitant syntactic language…

Reports of associated disabilities among children with specific language impairment (SLI) and children with other developmental disabilities are widespread. Clinicians require a broader definition of SLI that recognizes associated disabilities because it is their goal to impact children's everyday functioning. In this paper, we explore SLI from a…

This article criticizes the term "comorbidity" used to describe the overlap of developmental syndromes or disorders. Data from 179 school-age children are evaluated for criteria of seven disorders. Since fully 50 percent of the sample met the criteria for at least two diagnoses, the premise that these disorders are discrete categories on…

Three databases were analyzed to investigate the range and frequency of terms in the field of mental retardation/developmental disabilities. The most prevalent term over the last 15 years was "mentally retarded." The terms "cognitive impairment" and "developmental disabilities" have been used more frequently in the last five years.

It is argued the proposed definition of dyslexia is restricted to developmental dyslexia in which a student struggles to learn to read and does not apply to acquired dyslexia in which a previously normal reader loses reading functions. The need for classification schemes for defining specific learning disabilities is emphasized. (Contains…

This article discusses using the term "general learning disorder" instead of "mental retardation." It addresses the offensiveness of the current label, discusses ingredients needed in a more appropriate diagnostic term, and offers a proposed grouping of developmental disabilities based on cognitive ability, language ability, physical ability, and…

The effects of broadening the definition of eligibility for services from the Washington State Division of Developmental Disabilities (DDD) are analyzed. Five different definitions are discussed. The existing definition includes: (1) "statutory conditions," which includes persons who are mentally retarded or have difficulty carrying out…

This commentary discusses whether the American Association on Mental Retardation should change its name. It argues that the term "mental retardation" should become an historical artifact of the evolution of our thinking about children and adults with developmental disabilities. The plurality of the term "developmental…

This manual presents information about major causes of developmental disabilities, discusses strategies to prevent development disabilities, and identifies relevant resources and reference material. Introductory information defines developmental disabilities and prevention (under Virginia statutes). The first section considers causes prior to and…
