This cognitive assessment tool can be administered to children from aged 2 years and 6 months to 6 years and 11 months in the Lower Battery and an Upper Batter that can be administered to children up 17 years and 11 months and provides detailed information about your childs cognitive functioning. A cluster analysis procedure was used to identify subgroups of children who manifested specific learning disabilities in reading (SLD/R) in terms of performance on a battery of eight language and perceptual tests, finding some significant differences in measures of oral reading and reading comprehension skills. WebThe Differential Ability Scales (2nd ed., DASII) is unique in that it goes beyond cognitive ability testing to give insight into how a child processes information. The DAS-II can be scored manually or with the Scoring Assistant software included in every kit. Sattler (2001) Review of the DAS.

The limitations of standardized testing for children with developmental delay or cognitive impairment are well known: Tests do not exist that provide developmentally appropriate material along with norms that extend to the lower reaches of ability. Price includes up to 40 people per session. This test provides an overall measure of cognitive abilities, referred to as a Full Scale Battery. Individual composite scores, including memory, analogic reasoning (thinking about similarities through comparison), spatial awareness, and numerical reasoning can also be collected and are used by psychologists to determine your childs abilities in these areas. Compared DAS II with Mullen Scales of Early Learning (MSEL). Scores on the DAS-II and MSEL were highly correlated, suggesting that they measure a similar construct. Indices assessed include Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed. Children traditionally labeled learning disabled, mildly emotionally disturbed, and mildly mentally retarded are considered within a behavioral rather than a categorical framework. A composite measure known as the Full Scale Intelligence Quotient (FSIQ) is also provided as an overall measure of a childs cognitive abilities. This reaction focuses on and. 0000003940 00000 n

This nonverbal cognitive assessment tool is used to assess individuals from age 5 to 21 who have language or hearing impairments and also individuals who have diverse cultural and socio-economic backgrounds. 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. 2. 0000026154 00000 n
