This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

Given the interdisciplinary influences on school psychology along with its requirement to comply with federal and state law in the United States, scientific progress in the area of cognitive assessment and specific learning disabilities (SLD) identification has experienced slow, if not stagnant, progress. Extrapolation of research from one…

Reading disorders, including reading comprehension disorders, are among the most common referrals for evaluation in schools. If that evaluation involves individually administered tests of reading, the examiner is faced with selecting at least one reading comprehension subtest that is inherently associated with specific task demands, such as a…

This study investigated whether a latent class of children with math difficulties (MD) or math learning disabilities (MLD) emerged within a heterogeneous sample of learners. A latent class analysis was computed on children (N = 447) in Grade 3 who were administered a battery of math, reading, and cognitive measures. The analysis yielded four…

Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability and validity of two proposed PSW methods: the concordance/discordance method (C/DM) and cross battery assessment (XBA) method. Cognitive assessment…

Researchers investigated the self-concept profiles of twice-exceptional students in relationship to their cognitive ability and participation in educational services. All subjects (N = 64) had high ability (IQ score at or above the 90th percentile) and were diagnosed with either an autism spectrum disorder (ASD; n = 53) or specific learning…

Examines the cluster profiles obtained using the Differential Ability Scale (DAS) for preschool children diagnosed with cognitive delay. These profiles were compared with DAS profile patterns previously reported for school-aged children diagnosed with learning disabilities. Cluster comparisons indicated profiles of cognitively delayed preschoolers…

Investigated the usefulness of the Halstead-Reitan Neuropsychological Test Battery (HRNB) in discriminating normal from learning-disabled young adults. Results supported previous research in demonstrating both that normals perform more adequately than brain-damaged subjects on all HRNB tests, and that normal and brain-damaged subjects can be…

Screening for early identification of learning problems must be done through effective identification procedures which assure all children an equal opportunity for quality education. In order to do this, it is necessary to identify the essential characteristics of an effective screening program, the ways these characteristics might be implemented,…

Locus of control had substantial overlap with intelligence, but not with achievement. Analysis suggested that cognitive style and locus of control did not make an appreciable addition to the prediction by IQ scores alone of achievement in second and third grade learning disabled females. (Author)

Compares the performance of learning disabled students on the WISC-R and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery. This study finds that learning disabled subjects performed more poorly on the Tests of Cognitive Abilities than on the WISC-R. (Author)

A study analyzed the assessment profiles of 48 young adults with giftedness and a learning disability (G/LD) and 46 young adults with a learning disability profile without giftedness. Findings indicate that the adults with G/LD tended to be identified later and have more discrepancy among cognitive assessment profile scores. (Author/CR)

This study involving 30 college students with learning disabilities and 30 students without learning disabilities (ages 18-30) compared results obtained on the Wechsler Adult Intelligence Scale-Revised and the Kaufman Adolescent and Adult Intelligence Test. Results found no significant differences between the two groups or between tests.…

Three-year-old children (n=41) with mild learning problems and 41 typical children were given a battery consisting of seven simple cognitive tasks shown to contribute toward the differentiation of children with and without mild learning problems. Picture identification, oppositional concepts, identity discrimination, and semantic…

Ipsative subtest pattern stability was examined for 60 preschool children (31 males and 29 females) on the Bracken Basic Concept Scale and the Kaufman Assessment Battery for Children over a 4-6 week test-retest interval. The moderate level of profile stability found warrants cautious use of the ipsative interpretation approach. (SLD)
