Follow your gut? Emotional intelligence moderates the association between physiologically measured somatic markers and risk-taking.

Emotional Intelligence (EI) is a set of adaptive skills that involve emotions and emotional information. Prior research suggests that lower EI individuals behave maladaptively in social situations compared to higher EI individuals. However, there is a paucity of research on whether EI promotes adaptive decision-making. Leveraging the somatic marker hypothesis, we explore whether EI moderates the relationship between skin conductance responses (SCRs) and risky decision-making. In two separate sessions in the behavioral lab, participants (N = 52) completed tests of emotional intelligence and made a total of 5.145 decisions involving risk. At Time 1, participants completed an ability test of El and cognitive intelligence. At Time 2, participants completed 100 decision trials of the Iowa Gambling Task (IGT). Consistent with prior research using the IGT, participants played a computerized card game with real monetary rewards in which two "safe" decks led to higher average monetary rewards and two "risky" decks led to higher average losses. We found that EI moderates the relationship between physiological arousal, as measured by SCRs, and risk-taking. Specifically, lower EI individuals exhibited a maladaptive, positive association between SCRs and risk-taking, whereas higher EI individuals did not exhibit a relationship between SCRs and risk-taking. Our findings suggest one important way in which low EI may lead to maladaptive decision-making is through appraising physiological arousal incorrectly.
