Randomized trial examines decision-making effects of cognitive control and reward sensitivity in adolescents, suggesting targeted interventions.

This study aims to understand how cognitive control and reward sensitivity independently affect adolescents' decision-making under uncertainty.
Two-wave longitudinal design with 339 early adolescents (M = 13.38 years at baseline) over one year.
Three cognitive tasks were administered: Stroop for cognitive control, Monetary Incentive Delay for reward sensitivity, and Iowa Gambling Task for uncertain decision-making.
Computational modeling applied to decompose IGT performance into latent cognitive parameters at varying task stages.
Cognitive control predicted better performance in late-stage IGT (β = 0.13).
Reward sensitivity positively correlated with early-stage IGT performance (r = 0.15).
Computational modeling indicated that reward sensitivity increased loss aversion and poorer cognitive control decreased outcome sensitivity during decision-making.
