Learning disabled boys were categorized on the basis of consistency of lowest WISC/WISC-R factor scores over time. The Consistent subgroup with lowest scores on factor 3 also displayed significant factor score discrepancy. The Inconsistent subgroup had varying lowest factor scores with no significant discrepancy, such variation not apparently related to a delay hypothesis. Patterns in the Consistent Factor 3 group could be suggestive of either a delay or deficit. / Group differences occurred frequently in patterns, rather than levels of performance, the Inconsistents displaying patterns similar to able learners. Disorders of sequential processing and abnormal right hemisphere specialization characterized the Consistent Factor 3 group, inefficient selective attention the Inconsistent group. Pervasive group differences in holistic versus sequential processing were related to the hemisphere specialization index and both were related to WISC-R discrepancy scores. Thus, factor score discrepancies may usefully define these subgroups. A model of hemisphere functioning was offered in explanation of these results.
