Loss sensitivity decreases with time of day in individuals. (A) We identified individuals (N = 2599) who completed the risky decision task on two different days between 08:00 and 22:00. Risk taking in loss trials increased with time of day within individuals. (B) Loss sensitivity (αloss), but not gain sensitivity (αgain) or loss aversion (log(λ)), decreased with time of day in this within-subject sample. Error bars represent bootstrapped 95% confidence intervals [*p < 0.05, **p < 0.01, ***p < 0.005]. (C) Loss sensitivity was lower for later plays in within-subject analysis. Error bars represent bootstrapped 95% confidence intervals. Data binned on differences less (N = 1,643) or more than 5 h (N = 956) are shown for illustration purposes. [*p < 0.05, **p < 0.01, ***p < 0.005].
