Note: ρ = risk aversion. λ = loss aversion. μ = choice consistency. Early-phase refers to the early-phase stress response period (anticipation), and late-phase refers to the late-phase stress response period (recovery). M = mean difference; numbers in brackets following mean difference indicate 95% confidence interval around the mean difference. D = Cohen’s d, indicating effect size.
