title: Cognitive imbalance and antisocial personality characteristics.
abstract: A cognitive imbalance, in which intellectual functioning is elevated in the performance area in comparison to verbal IQ, has been posited as an antecedent condition in relation to antisocial behaviors. The current investigation was based on the notion of a developmental arrest in which verbal, analytical, controlling brain processes (analogous to verbal IQ) fail to develop commensurately with the more impulsive actions mediated by the motor areas of the cerebral cortex (analogous to performance IQ). The simple verbal IQ performance IQ discrepancy index used in prior studies was reformulated as a causal theoretical model consisting of shared and unique performance IQ variance. The participants were 325 adults including 141 prison inmates. They were administered the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Psychopathic Deviate (Pd) and Mania (Ma) scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). These were the manifest (measured) variables in the model tested by means of structural equation modeling procedures. Several statistical indices suggested an excellent model-data congruence.
