We compared the Wechsler scores of individuals with twice-exceptionality (2e) and giftedness using a three-level Bayesian meta-analysis. Ninety-five effect sizes were calculated from 15 studies (n = 2,106). Results show that individuals with 2e who have learning disabilities perform lower than individuals with giftedness in Full-Scale Intelligence…

The present study examined oral language growth differences in a sample of 256 Greek-speaking children with and without literacy difficulties (LD), during the first two elementary grades. Measures of vocabulary, phonological awareness (PA), morphological awareness (MA), and rapid automatized naming (RAN) were administered in both grades for the…

The Mobile Autism Risk Assessment (MARA) is a new, electronically administered, 7-question autism spectrum disorder (ASD) screen to triage those at highest risk for ASD. Children 16 months-17 years (N = 222) were screened during their first visit in a developmental-behavioral pediatric clinic. MARA scores were compared to diagnosis from the…

The Naglieri Nonverbal Ability Test, Second Edition (NNAT2), is used widely to screen students for possible inclusion in talent development programs. The NNAT2 claims to provide a more culturally neutral evaluation of general ability than tests such as Form 6 of the Cognitive Abilities Test (CogAT6), which has Verbal and Quantitative batteries in…

The cognitive and academic profiles of high ability students with autism spectrum disorder were examined. Inclusion criteria were a diagnosis of autism (high functioning) or Asperger syndrome and at least one ability and/or achievement index standard score of 120 or above. Results indicated that despite the restricted range of cognitive abilities,…

The study was conducted to look at differences between children who outgrew and did not outgrow an early diagnosis of mathematical learning disorder (MD; n=13), and peers without MD (n=13). Children were tested at 5, 6, 7 and 10 years of age. About 54% of the children with an early diagnosis of MD still experienced mathematical difficulties at the…

The General Ability Index (GAI) is a composite ability score for the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) that minimizes the impact of tasks involving working memory and processing speed. The goal of the current study was to compare the degree to which the Full Scale IQ (FSIQ) and the GAI predict academic achievement…

Investigated joint factor structure of Differential Abilities Scale and Wechsler Intelligence Scale for Children-Revised for 115 children. Compared theoretically supportable models (Spearman's General factor; Wechsler's Verbal, Performance, and Freedom from Distractibility factors; Elliott's verbal, nonverbal, spatial, and diagnostic perspective)…

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…

Wechsler Intelligence Scale for Children, Revised (WISC-R) Verbal, Performance, and Full Scale IQ's were compared with Bannatyne recategorized WISC-R scores for groups of non-handicapped, educationally disadvantaged, learning disabled, and regular classroom Navajo Indian children. No definitive evidence was found to support the use of the…

Using Otis-Lennon Mental Ability Test, Elementary II Level and WISC Verbal Performance and Full Scale IQs of 40 white children, correlations of .71, .57 and .73, respectively, were computed. Results suggest IQs and should be interpreted with caution when used as criterion for identifying mentally retarded white children. (Author)

The third edition of the Wechsler Intelligence Scale for Children (WISC-III) is reviewed. A comparison of the WISC-III with the Weschler Intelligence Scale for Children-Revised (WISC-R) is included. Discusses shortcomings of the WISC-III while noting that overall, there are substantial improvements in the WISC-III over the WISC-R. (KW)

Concern about the possible bias of using only verbal assessments for the identification of intellectually gifted students led to an examination of the effect of incorporating nonverbal assessments of intelligence into the identification process. Two nonverbal instruments (Progressive Matrices and Test of Nonverbal Intelligence) were used in…

Administered an ability scale to 53 children identified as having a learning disability approximately three years after each had been administered an intelligence scale. Results indicate that the ability scale correlated highly with the intelligence test. Differences in scores in specific measures were nonsignificant. Other findings are discussed.…

Comparisons of Wechsler Intelligence Scale for Children-Revised scores, for 24 children with learning disabilities demonstrating a low verbal, high performance intelligence quotient (IQ) discrepancy and 33 slow learning children having uniformly low verbal and performance IQs, revealed few cognitive differences beyond the Performance Scale…
