Neuropsychological significance of variations in patterns of academic performance: verbal and visual-spatial abilities.

Forty-five 9- to 14-year-old children with learning disabilties whose WISC Full Scale IQs fell within the range of 86-114 were divided into three groups on the basis of their patterns of reading, spelling, and arithmetic achievement. Group 1 was composed of children who were uniformly deficient in reading, spelling, and arithmetic; children in Group 2 were relatively adept at arithmetic as compared to their performance in reading and spelling; Group 3 was composed of children whose reading and spelling performances were average or above, but whose arithmetic performance was relatively deficient. The performances of these children on 16 dependent measures were compared. The performances of Groups 1 and 2 were superior to that of Group 3 on measures of visual-perceptual and visual-spatial abilities; Group 3 performed at a superior level to that of Groups 1 and 2 on measures of verbal and auditory-perceptual abilities. The results are discussed in terms of the relationships between varying patterns of academic abilities and patterns of brain-related behaviors, and the nature of the neuropsychological abilities that may limit performance on arithmetic calculation tasks.

Prediction of the reading and spelling performances of normal and retarded readers: a four-year follow-up.

The purpose of this study was to determine the relative predictive accuracy of a number of measures employed in a 4-year longitudinal study of the neuropsychological abilities of normal and retarded readers. The results indicated that there were some very accurate predictive measures of reading and spelling achievement levels over the 4-year age span studied, and that the relative accuracy of these measures differed markedly for normal and retarded readers. Especially in the case of retarded readers, performance of the Underlining Test was a much more accurate predictor of eventual achievement levels in reading and spelling than were tests of reading, spelling, or psychometric intelligence.

Comparisons of cutoff and regression-based definitions of reading disabilities.

This study addressed the issue of specificity in reading disability by comparing two approaches to defining and selecting children with reading disabilities. One approach defined reading disability according to cutoff scores representing appropriate levels of intelligence and reading deficiency, whereas the other approach adjusted these scores for their intercorrelation through regression procedures. Results revealed clear differences in which children were identified as reading disabled according to the two definitions. However, differences in neuropsychological performance between children whose reading scores were discrepant or not discrepant with IQ were small and nonspecific for both definitions. The results of this study show that children identified as reading disabled vary according to the definition employed; at this point, there is little evidence suggesting any specificity of reading disability according to definition.

Disabilities of arithmetic and mathematical reasoning: perspectives from neurology and neuropsychology.

Current research on brain-behavior relationships in disabilities of arithmetic and mathematical reasoning is reviewed from both a neurological and a neuropsychological perspective. Although no entirely satisfactory statement of the relationship between arithmetic skills and brain functions has yet emerged, investigators in this area have provided evidence regarding the involvement of some brain systems in processes of calculation. Also, the developmental importance of right- versus left-hemisphere integrity for the mediation of arithmetic learning and performance has been suggested. We propose that an account of brain-behavior relationships in children intended to explain and predict developmental disabilities of arithmetic learning needs to address several important content and processing distinctions in order to (a) encompass empirically derived subtypes of children with learning disabilities who exhibit difficulties with arithmetic and (b) provide adequate direction for future subtyping and intervention research.

Psychosocial dimensions of learning disabilities: external validation and relationship with age and academic functioning.

This study was designed to assess the following in a group of 152 children with learning disabilities between the ages of 7 and 13 years: (a) the relationships between age and psychosocial functioning: (b) the relationships among psychosocial functioning, cognitive abilities, and academic achievement; and (c) the external validity of statistically derived psychosocial subtypes. Participants were assigned to one of seven psychosocial subtypes on the basis of a profile-matching algorithm. Overall, the findings suggested no increase in psychopathology with advancing age. In addition, clear relationships were found between academic achievement patterns and personality subtypes. Finally, the subtypes could be distinguished on the basis of a behavior problem checklist not used for the construction of the subtypes.
