Abstract
Individuals with psychopathic traits are hypothesized to be free of intellectual deficits and possibly even to exhibit good cognitive abilities. Previous studies, based on clinical and incarcerated youth, have shown inconsistent findings. We investigated the relationships between different dimensions of psychopathy (callous/unemotional traits, narcissism, impulsivity) and cognitive abilities in a large population-based sample of children (age 9, N=4,713). Findings indicated a positive relationship between narcissism and both verbal and nonverbal abilities, even after accounting for conduct problems and hyperactivity. Callous/unemotional traits and impulsivity were negatively related to both types of cognitive abilities but did not remain significant after accounting for conduct problems and hyperactivity. Interactions between gender and the dimensions of psychopathy were not significant.
