Theories of adolescent risk taking posit that immature cognitive control coupled with heightened reward reactivity drive adolescent risk-taking, yet surprisingly few empirical studies have examined these neurobiological systems together. In this paper, we describe a related series of studies from our laboratory aimed at further delineating the maturation of cognitive control through adolescence, as well as how rewards influence a key aspect of cognitive control, response inhibition...
