Children traditionally labeled learning disabled, mildly emotionally disturbed, and mildly mentally retarded are considered within a behavioral rather than a categorical framework. In particular, they often have tro uble with phonological processing, which is a robust predictor of, Abstract A normative typology was developed and applied using multivariate profile analysis of subtest scores of the Universal Nonverbal Intelligence Test (UNIT) standardization sample. The purpose of this study was to determine whether distinct subgroups of children with learning disabilities could be identified using a single, recently developed instrumentthe Differential Ability Scales (DAS). An overall measure of cognitive abilities, referred to as the Intelligence Quotient (IQ), can also be obtained. It provides specific information about several areas of a childs cognitive abilities, including verbal skills, nonverbal problem-solving, and spatial awareness. The difference between overall scores is suggested to be attributable to a relative weakness in processing speed, which is assessed on the WISC-IV but not the DAS-II. Concurrent validity of the WISC-IV and DAS-II in children with autism spectrum disorder. We conclude that interchanging MSEL and DAS-II scores without regard to the discrepancy in scores may produce misleading results in both cross-sectional and longitudinal studies of children with and without ASD, and, thus, this practice should be implemented with caution. 0000050086 00000 n wechsler nonverbal sample report .

Elliott reflect theories that focus on measuring diverse skills. Psychologists use this to provide information on a childs logical problem-solving, verbal and nonverbal knowledge, numerical reasoning, working memory, visual-spatial processing, which is the ability to organize information into meaningful patterns and understanding how they change as they move through space. 4. Concerns about the ability-achievement discrepancy method for specific learning disability (SLD) determination led to alternative research-based methods, such as failure to respond to intervention. Price includes up to 40 people per session. This test provides an overall measure of cognitive abilities, referred to as a Full Scale Battery. This study was an effort to subtype adolescents' learning disabilities using scores on the Woodcock-Johnson Psycho-Educational BatteryRevised to characterize subtypes, suggesting that these students had two specific types of learning disorders.
