Abstract

The present study examined behavioral and neural differences in risky decision-making between delinquent (n = 23) and non-delinquent (n = 27) youth ages 13-17 years (M = 16, SD =.97) in relation to reward processing. During fMRI, participants completed an experimental risk task wherein they received feedback about the riskiness of their behavior in the form of facial expressions that morphed from happy to angry. Behavioral results indicated that delinquent youth took fewer risks and earned fewer rewards on the task than non-delinquent youth.

RESULTS from whole-brain analyses indicated no group differences in sensitivity to punishments (i.e., angry faces), but instead showed that delinquent youth evinced greater neural tracking of reward outcomes (i.e., cash-ins) in regions including the ventral striatum and inferior frontal gyrus. While behavioral results show that delinquent youth were more risk-averse, the neural results indicated delinquent youth were also more reward-driven, potentially suggesting a preference for immediate rewards.

RESULTS offer important insights into differential decision-making processes between delinquent and non-delinquent youth.
