We examined the relationship of preinjury intelligence, a lesion-severity variable (brain-tissue loss volume), and lesion location to persistence cognitive deficits in Vietnam veterans with penetrating brain wounds. Using stepwise multiple linear regression procedures, we found that intelligence predicted significant amount variance on postinjury testing, being better predictor for tests requiring number complementary processes (e.g., tests) than measuring specific process face recognition). Brain-tissue volume was play larger role when global measure used, but smaller measured. Finally, shown be performance only processes. Nevertheless, intelligence/education appears an even either brain-tissue or particular structural loss.
