Adolescent Brain Response to Reward Is Associated with a Bias toward Immediate Reward

ABSTRACT

The current study examines associations between neural activation to the receipt of monetary reward in a rewarding game task and bias toward immediate reward measured in a behavioral delay discounting task among early adolescents (N = 58, 12–14 years). As expected, heightened brain activation in reward-related regions were correlated with higher bias toward immediate reward. This suggests that bias toward immediate reward in delay discounting tasks may be linked to heightened activation to reward in reward processing regions. This interplay between neural reward processing and bias toward immediate reward might explain the sharp increases in bias toward immediate reward that occur in early adolescence.
