Indices assessed include Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed. This longitudinal study results indicated that nonverbal cognitive scores (NVIQ) in individuals with ASD declined between toddlerhood and adulthood, particularly among those whose scores were below 70. 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. Autistic symptomatology was not associated with cognitive scores, while adaptive behavior was positively associated. 8600 Rockville Pike SAMPLE PSYCHOEDUCATIONAL REPORT Atlanta Pediatric The .gov means its official.

DAS provides extended age ranges and out-of-level testing, The WISC-R was administered to a group of learning-disabled (LD) children and the results factor-analyzed. The site is secure. Differential Ability Scales 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. 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.

Farmer, C., Golden, C., & Thurm, A. The use of the British Ability Scales with children having specific reading difficulties is described and it is suggested that the four abilities recommended for use in computing an IQ in the current BAS Manual are inappropriate for the dyslexic child.
