Group comparison reveals that the propranolol group has significantly lower indifference point parameters for both the fixed (pf) and the decreasing (pd) condition. This means that their urgency arises earlier in an information-gathering process and thus drives them to make more hasty decisions. None of the other parameters was significantly different. Data are shown as mean ± SD.
