WebIntellectual ability tests measure the abilities of an individual child relative to the abilities of children in the general population. In addition to the core subtests, ten diagnostic subtests are available to measure verbal and visual working memory, immediate and delayed recall, visual recognition and matching, processing and naming speed, phonological processing, and understanding of basic number concepts. The nature and the structure of children's abilities are considered in the light of evidence from the Differential Ability Scales (DAS), a newly published, individually administered cognitive test, The purposes of this research were, first, to determine whether the varied tests contained in the Differential Ability Scales (DAS) measure the same constructs across its wide range, and, second, to, In a study of the construct validity of composite and selected subtest scores of the Differential Ability Scales (DAS), scores from the DAS, WISC-R, and Stanford Achievement Test were compared for 46, The Differential Ability Scales (DAS) is a scale developed in the British empirical tradition and is purported to be useful in making educational decisions for children.

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. It can be administered to children aged 3 years to 16 years and 11 months and provides norm-based scores in the areas of executive functioning (mental skills are used to complete tasks), attention, language, memory, learning, sensorimotor abilities, visual-spatial processing (mentally moving objects around), and social perception (forming impressions of and make inferences about others). 0000050704 00000 n (2015).
