Presents evidence to show variability across states in the use of the severe-emotional-disturbance designation for students and the frequency of comorbid and trimorbid cases being classified as learning disabled. Findings are presented from ongoing projects to illustrate differential profiles for comorbid children. (Author/CR)

Examines issues in the differential diagnosis of autism in preschool children with significant cognitive impairment, including the use of traditional diagnostic guidelines for preschoolers with developmental delays, developmental changes in behavioral characteristics, involvement of cognitive factors in symptom expression, overlap between autism…

Comments on studies that indicate delayed onset of canonical babbling may predict future language impairments. It cautions against the too-early assumption of the use of early perceptual and production capacities as clinical markers and warns that using lack of canonical babbling as a early index of language delay could lead to a high rate of…

This study evaluated an experimental articulation testing instrument for differentiating child speakers (N=21, ages 5:0 to 6:6) of African-American Vernacular English (AAVE) with atypical and typical phonologies. Significant group differences were observed, suggesting that the measure can differentiate typical and atypical development in this…

Ten students (age 10) with dyslexia were compared to 10 chronological-age controls and 20 reading-age controls. Response latencies of the students with dyslexia were slower when familiar words, letter clusters, and nonwords had to be named. A larger word-frequency effect and larger word-length effect indicate difficulty with increasing task…

Three studies are reported addressing the reliability of the Scale for Assessing Emotional Disturbance (SAED), a standardized, norm-reference measure linked to the federal definition of emotional disturbance (ED). Results indicate the SAED possesses acceptable test-retest reliability and reasonable interrater reliability and can assist in the…

A study examined the stability of the six subgroups of 242 English children with language impairment at age 8. Findings indicate considerable stability in the patterns of difficulties delineated by the classification system. Poorer stability was evident across time with 45% the children moving across subgroups. (Author/CR)

A study of 684 individuals yielded special population norms on the Vineland Adaptive Behavior Scales for individuals with autism for mute children under 10, children with some verbal skills under 10, mute individuals who are 10 or older, and individuals with some verbal skills who are 10 or older. (Author/CR)

Discusses hypotheses and methodologies needed to extend understanding of the ethnic representation of students with serious emotional disturbances. Technical methods are discussed to ensure that estimates for the extent of disproportionate representation are accurate. Research needed to produce better conceptual understanding of why…

Discusses the definition of dyslexia, reintroduces the concept of marker variables, proposes a strategy for developing an updated marker variable system, presents a preliminary working set of dyslexia marker variables, and calls for eventual adoption of this or similar marker variable systems to facilitate future research efforts. (Author/CR)

This article reviews "Facing Learning Disabilities in the Adult Years" by Joan Shapiro and Rebecca Rich, a book that discusses the definitions, causes, and characteristics of learning disabilities as well as many interventions for successful adult adjustment. The information is aimed at helping families and professionals, as well as the adults…

The accuracy of 3 developmental screening tests administered to 89 young children was compared. The Battelle Developmental Inventory Screening Test was more accurate than the Academic Scale of the Developmental Profile-II and the Denver-II, identifying correctly 72% of children with difficulties and 76% of children without diagnoses. (Author/JDD)

Presents an overview of the context and clinical principles of the use of developmental screening instruments (DSIs) to identify children with developmental disabilities that would not be recognized without their use. Offers guidelines for evaluating and using DSIs. Explains reasons for using DSIs in pediatric clinical settings and why they have…

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. (CR)

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)
