Abstract

One feature of adolescence is a rise in risk-taking behaviors, whereby the consequences of adolescents' risky action often impact their immediate surrounding such as their peers and parents (vicarious risk taking). Yet, little is known about how vicarious risk taking develops, particularly depending on who the risk affects and the type of risky behavior. In a 3-wave longitudinal fMRI study, 173 adolescents completed 1-3 years of a risky decision-making task where they took risks to win money for their best friend and parent (N with behavioral and fMRI data ranges from 139-144 and 100-116 participants, respectively, per wave).

RESULTS of this preregistered study suggest that adolescents did not differentially take adaptive (sensitivity to the expected value of reward during risk taking) and general (decision-making when the expected values of risk taking and staying safe are equivalent) risks for their best friend and parent from sixth to ninth grade. At the neural level, preregistered ROI analyses revealed no differences in the ventral striatum and ventromedial pFC during general nor adaptive risk taking for best friend versus parent over time. Furthermore, exploratory longitudinal whole-brain analyses revealed subthreshold differences between best friend and parent trajectories within regulatory regions during general vicarious risk taking and social-cognitive regions during adaptive vicarious risk taking. Our findings demonstrate that brain regions implicated in cognitive control and social-cognitive processes may distinguish behaviors involving peers and parents over time.
