This article presents the author's comments on Simon and Lichten's "Defining Mental Retardation: A Matter of Life and Death." Lichten and Simon (2007) argued for the use of a Total Quotient (TQ) that combines existing IQ and adaptive functioning scores into a single index. They proposed that the TQ index will improve the accuracy of mental…

A reaction to the review of replicated findings concerning stuttering cites disagreement with the definition of stuttering used and notes implications for findings on treatment, clinical effects, recovery, stutterer-nonstutterer differences, and theory. (CL)

The author examines implications of the P.L. 94-142 (the Education for All Handicapped Children Act) definition of learning disability, and cites two cases to illustrate two basic problems: that the definition is both overinclusive and underinclusive, and that it does not consider underlying causes. (CL)

This paper argues against definitions of stuttering which imply that all within-word disfluencies are stuttering and no between-word disfluencies are stuttering. The paper calls for a definition of stuttering that is not contradicted by available empirical information or clinical experience and is logically consistent. (JDD)

Long-term follow-up studies show that children diagnosed as hyperactive are at risk for severe problems during adolescence and adulthood. However, no common diagnostic criteria exist for hyperactivity, which can refer to many different behaviors, and children diagnosed as hyperactive may also exhibit one or more concomitant difficulties. Journal…

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…

The definition of mental disorder in the third edition of the "Diagnostic and Statistical Manual of Mental Disorders" (DSM-III-R) explains that a disorder is harmful and represents a dysfunction, but it fails to capture the idea of dysfunction. Ideas for increasing the conceptual validity of the definition are presented. (SLD)

The author suggests that controversies over defining learning disabilities (LD) have resulted from confusion between diagnosis and definition and from disagreement over the discrepancy issue. He further suggests that LD students are a subset of age- and ability-referenced underachievers. (CL)

The paper argues that listeners are unable to judge unit-by-unit occurrences of stuttering acceptably. Reasons for this state of affairs and its implications for therapy, theory, and research are analyzed. An alternative speech production definition with its implications is proposed, and a diagnostic method of validating authentic stuttering is…

Presents a model for strategic, therapeutic interventions to help children stop repetitive behavioral sequences that offer protection from painful losses, but block the grief process. (Author/RH)

Identification, differential diagnosis, and treatment evaluation of emotionally disturbed preschoolers by practitioners are considered. Emphasis is on the need for defining disorders in terms of: (1) a broad normative context to assist general reporting within the profession; and (2) specific settings to provide the information necessary for…

Discusses what children with developmental language disorders should be called, how they should be defined, and how we might differentiate children with specific language impairments from other children with developmental language disorders. The lack of congruence between clinical and research constructs is discussed. (Author/CR)

The characteristic features of psychogenic stuttering of adult onset are reviewed, and four cases of this disorder are presented. Psychogenic stuttering of adult onset is classified as a conversion reaction, and tentative criteria for this diagnosis are proposed. (Author/JDD)

The use of intelligence quotient alone for defining mental retardation is inappropriate and potentially harmful when applied to individuals or used to formulate public policy. An alternative conceptual framework for defining mental retardation within the context of interactions between an individual's characteristics and the demands of the social…

This article proposes the use of a rehabilitative diagnostic approach to evaluate individuals having communication disorders in the context of the International Classification of Impairment, Disabilities and Handicaps (ICIDH). It suggests the use of computer-assisted communication aids and offers guidelines for using such aids to assess…
