Social anxiety, acute social stress, and reward parameters interact to predict risky decision-making among adolescents

Highlights • We tested effects of social anxiety, social stress and rewards on risk-taking. • Reward value influenced risk-taking in those with high but not low social-anxiety. • Social stress affected reaction time in those with low but not high social-anxiety. • Those with high social anxiety evidenced greatest RT on the most negative trials. • Effects of context and reward parameters depended on level of trait social anxiety.
