ABSTRACT
A total of 132 children with learning disabilities (LD) between the ages of 6 and 12 years were divided equally into 3 groups on the basis of the difference between WISC VIQ-PIQ scores (viz., VIQ greater than PIQ, VIQ = PIQ, and VIQ less than PIQ). The mean Personality Inventory for Children (PIC) profiles for the VIQ = PIQ and VIQ less than PIQ groups were normal; however, the VIQ greater than PIQ group showed pathological elevations on some PIC scales. Group average linkage cluster analysis using 10 PIC scales revealed 6 psychosocial subtypes. Within these subtypes, children with VIQ greater than PIQ were found at lower than expected frequencies in normal and mildly disturbed subtypes, but at higher than expected frequencies in seriously disturbed subtypes. These results support the notion that patterns of cognitive performance are related to patterns of psychosocial functioning in children with LD.

Investigation of the neuropsychological sequelae of brain tumors is extremely complex largely because the neurobehavioral consequences of brain tumors depend upon complex interactions among disease and treatment variables as well as patient characteristics. To illustrate some of these complexities, we present case studies of two patients in whom the behavioral outcome was not easily predictable on the basis of our current understanding of brain-behavior relationships in tumor patients. The case studies do illustrate how neuropsychological evaluation aids in identifying cognitive deficits which have implications for subsequent quality of life. Recommendations for future experiments and statistical analyses of neurobehavioral data of this population are given.

The PIC scores of 132 learning-disabled children between the ages of 6 and 12 years were investigated using Q-factor analysis, four hierarchical-agglomerative clustering techniques, and one iterative partitioning clustering technique. Results revealed excellent correspondence between the subtypes derived by all grouping methods in terms of both misclassifications and mean PIC profile similarity of the subtypes across techniques. The mean PIC profile of one subtype indicated normal psychosocial adjustment; a second subtype exhibited evidence of significant internalized psychopathology; a third subtype had a mean PIC profile suggestive of externalized psychosocial maladjustment. These subtypes were virtually identical to three subtypes reported by Porter and Rourke (1985) in another study of learning-disabled children. The results indicate that learning-disabled children comprise a heterogeneous population in terms of psychosocial functioning and that subtypes of learning-disabled children with similar patterns of socioemotional adjustment can be recovered reliably from this population across samples and statistical grouping techniques.
