title: A neuropsychological approach to the Bannatyne recategorization of the Wechsler Intelligence Scales in adults with learning disabilities.
abstract: An investigation was conducted of the diagnostic ability of the Bannatyne recategorization of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) into spatial, verbal-conceptual, and sequential components for adults with learning disabilities. A comparison among neuropsychological, intelligence, and achievement test data was made to evaluate the applicability of this recategorization. The Luria-Nebraska Neuropsychological Battery (LNNB), the WAIS-R, and the Wide Range Achievement Test-Revised (WRAT-R) were administered to 103 adult subjects with learning disabilities. The LNNB scales were cluster analyzed, and cluster membership was cross-tabulated against WAIS-R, WRAT-R, and demographic data. The major findings were that (a) the mean scores fit the Bannatyne pattern in two of the four clusters; and (b) the Bannatyne pattern was found in only about 20% of the total sample. It was concluded that identification of the Bannatyne pattern is of diagnostic utility, but its absence is inconclusive.
