A case study is presented of a Brazilian adolescent with a behavioral profile meeting the criteria of autism. After clinical and laboratory examinations, it was found that he had an abnormal karyotype. The need for case studies to develop data for defining an etiological basis for diagnosis is emphasized.

Evaluation of 357 students with either learning disability (LD), serious emotional disturbance (SED), or both (SED/LD), ages 6 to 18, found that children with LD differed from those with SED mainly in terms of severity of problem, not type of problem. Results suggest that students with both LD and SED are under-identified and underserved. (DB)

Identifies subgroups of children with reading disabilities using the regression method--children who were poor in phonological, compared to orthographic, word decoding were identified as phonological-type participants, and children who were poor in orthographic, compared to phonological, decoding were identified as surface-type participants.…

This article examines a 1995 treatment validity model as a framework for identifying learning disabilities. This model: (1) examines both student performance and responsiveness to instruction; (2) delays special education referral until the effects of individual student adaptations in the regular classroom have been explored; and (3) verifies that…

Studies the group decision-making process of the evaluation of preschool children with complex disabilities. Sequential application of processes was found to be influenced by the occurrence of a series of three cycles of decision making within each assessment and the decomposition of the assessment task into distinct subproblems. (Contains 67…

Predictive value of maternal age and education in relation to rates of mental retardation in a 3-year-birth cohort (n=267,277) was studied. Low maternal education placed individuals at increased risk for both educable mentally handicapped and trainable mentally handicapped placement. Older maternal age was associated with increased risk of mental…

This article discusses six criteria for justifying universal infant hearing screening, including: significant consequences must result when the disorder is not detected, programs must be available, accessible, and cost-effective, and birth-admission screening must result in an improved outcome. It concludes that universal detection of infant…

Two studies used a scaling approach to measure components of modifiability in children. Modifiability differentiated between children having low language ability and typically developing children from culturally and linguistically diverse backgrounds. Furthermore, the individual components of modifiability, with the exception of motivation,…

This study evaluated application of a revised criterion for the Language Development Survey, a parent-report screening measure designed to identify young children with language delays. The revised criterion generated fewer false positives, improved specificity, and improved positive predictive value while maintaining the high sensitivity and high…

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 study compared the working memory abilities of children identified as having special educational needs with those making normal academic progress at ages 7 and 8. Special needs children showed marked working memory impairments, especially on tasks tapping central executive functions. Results have implications for identifying children at risk…

To examine the possibility of gender bias in special education referral and admission, this study reviewed records of 695 students admitted to special education over 3 years. Findings support the hypothesis that males are not necessarily overrepresented in the special education population but, instead, females who could benefit from special…

An ecological niche framework (Hacking, 1998) is utilised to examine the growth of ADHD in North America. The analysis suggests ADHD flourishes, at least in part, due to a complex and historically situated interaction of factors that created a niche within which a particular kind of explanation and treatment for the troubling behaviours of…

Using U.S. Department of Education data, the current study examined changes in the rates of special education eligibility classifications. This was done to determine if classification substitution might be an explanation for increases in the number of students being found eligible for special education using the Autism criteria. Results reveal…

Objective: To investigate parents' experiences of surveillance for early talking difficulties. Design: Qualitative study nested within a randomised controlled trial. Setting: Interviews with the parents of 20 children identified as having early difficulties. Results: Most parents were in favour of surveillance of children's language. Parents do…
