Abstract: Adolescents’ daily experiences navigating and managing complex social relationships with multiple distinct communities influence how they utilize different cognitive strategies or motivational resources in order to engage in self-control. This is particularly important given evidence that adolescents tend to have weaker activation in brain regions typically recruited during self-control. Here we test whether activity in social brain systems (self-processing and mentalizing systems) can be used to facilitate successful cognitive control, and whether adolescents’ social networks influence the brain networks they recruit to successfully regulate their behavior. We measured 62 adolescents’ brain activation while they completed a Go/No-Go response inhibition task. We also collected information about adolescents’ social networks. We find that recruitment of social brain systems (in particular the self-processing system) is associated with better response inhibition in adolescents, especially for adolescents who have weaker activation in response inhibition systems. Moreover, adolescents with larger social networks with more distinct communities show stronger relationships between brain systems and response inhibition. Collectively, our results provide insight into how brain systems facilitate cognitive control in adolescents.
