abstract="Social influences on decision-making are particularly pronounced during adolescence  and have both protective and detrimental effects. To evaluate how responsiveness to  social signals may be linked to substance use in adolescents, we used functional  neuroimaging and a gambling task in which adolescents who have and have not used  substances (substance-exposed and substance-naïve, respectively) made choices alone  and after observing peers' decisions. Using quantitative model-based analyses, we  identify behavioral and neural evidence that observing others' safe choices  increases the subjective value and selection of safe options for substance-naïve  relative to substance-exposed adolescents. Moreover, the effects of observing  others' risky choices do not vary by substance exposure. These results provide  neurobehavioral evidence for a role of positive peers (here, those who make safer  choices) in guiding adolescent real-world risky decision-making.<p /> <p>Language: en</p>",
