    Hedonic dysregulation is evident in addiction and substance use disorders, but it is not clearly understood how hedonic processes may interact with brain development related to cognitive control to influence risky decision making and substance use during adolescence. The present study used prospective longitudinal data to clarify the role of cognitive control in the link between hedonic experiences and the development of substance use during adolescence. Participants included 167 adolescents (53% male) assessed at four time points, annually. Adolescents participated in a functional magnetic resonance imaging (fMRI) session where blood-oxygen level dependent (BOLD) response was monitored during the Multi-Source- Interference Task to assess cognitive control. Substance use and hedonia were assessed using self-report. A two-group growth curve model of substance use with hedonia as a time-varying covariate indicated that higher levels of hedonia predicted higher substance use, but only in adolescents with higher activation in the frontoparietal regions and in the rostral anterior cingulate cortex during cognitive control. Results elucidate the moderating effects of neural cognitive control on associations between hedonia and adolescent substance use, suggesting that lower cognitive control functioning in the brain may exacerbate risk for substance use promoted by hedonia.

    Self-control and cooperation in childhood as antecedents of less moral disengagement in adolescence
    Gülseven, Zehra; Yu, Mark Vincent B.; Zarrett, Nicole; Vandell, Deborah Lowe; Simpkins, Sandra D. (Cambridge University Press, 2023-02-26)
    Moral disengagement is a social cognition people use to engage in wrongdoings even when they know it is wrong. However, little is known about the antecedents that predict moral disengagement. The current study focuses on the development of self-control and cooperation during middle childhood as two antecedents of moral disengagement among 1,103 children (50% female; 77% White, 12% Black, 6% Hispanic, and 5% other). Children's self-control at age 8 and growth in self-control from age 8 to 11 were positively linked to adolescents seeing themselves as having self-control at age 15, which then predicted less moral disengagement at age 18. Children's cooperation at age 8 also was positively linked to adolescents' self-views of cooperation at age 15, which in turn, was associated with less moral disengagement at age 18. These findings demonstrate the potential of self-control and cooperation as intrapersonal and interpersonal strengths during middle childhood for mitigating moral disengagement 10 years later.
