| Abstract: | Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic
symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth.
Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were negatively correlated with ERP measures of attentional alerting, indicating that youth with
psychopathic symptoms had difficulty using warning cues to prepare for upcoming targets. APSD total scores were not related
to performance on measures of orienting or executive attention, although weaker executive attention was found among youth
with higher scores on the Impulsivity subscale. These findings support attention-based models of psychopathy and provide evidence
of specific deficits in attentional alerting among youth with psychopathic traits. Deficiencies in attentional alerting may
be related to noradrenergic functioning and may have cascading effects on higher order cognitive and affective processing. |
