Personality/behavioral characteristics of empirically derived subgroups of learning disabled (LD) children (8-11 years old) were examined. A modified Halstead-Reitan battery was administered to 56 LD Ss. Their parents completed personality/behavioral measures. Ss' scores on 13 neuropsychological measures were cluster analyzed, and three subgroups were identified. Basically, it appeared that children in subgroup 1 exhibited the most severe and generalized deficits in performance; Ss in subgroup 2 showed a moderate degree of impairment and greater verbal deficits; and Ss in subgroup 3 exhibited the least amount of impairment with slightly greater deficits in visuo/spatial/motor functioning. Data from the Personality Inventory for Children and the Child Behavior Checklist were analyzed, and four dimensions identified. Results were discussed in terms on neuropsychological characteristics.
