title: Digit repetition in learning-disabled children.
abstract: Investigated digit repetition performance in learning-disabled children in an effort to assess its clinical and theoretical significance. Clinically, learning-disabled children were found to demonstrate a higher than expected incidence of large verbal-performance discrepancies, although mean overall digit repetition performance did not differ appreciably from that expected on the basis of intelligence (N = 100). Children with large discrepancies did not differ from those with no such discrepancies when compared on a variety of psychometric and neurobehavioral factors. Theoretically, a hemispheric specialization model and a neuropsychological function model have been proposed to underlie performance on the two somewhat different digit repetition tasks (forward and backward repetition). Some support was found for the neuropsychological function model, with significant correlations obtained between digits forward and a measure of language function and between digits backward and a test of visual constructional ability. Stronger evidence that could have been provided by a double dissociation of correlational findings was limited by a smaller, but significant, correlation between digits forward and Bender Gestalt errors. However, the results are consistent with previous research in suggesting that digit repetition can be an avenue to the study of brain-behavior relationships.
