a
Breath alcohol concentration (g/dl) at 10, 25, and 60 minutes after beverage consumption;
b
Trail Making Test A: trend-level dose effect, F(2, 84) = 2.95, p = .06; low-dose group (M = 21.53, SD = 3.18 sec.) performed somewhat better than the moderate-dose (M = 24.53, SD = 6.98 sec.) and placebo (M = 24.47, SD = 5.71 sec.) groups;
c
Trail Making Test B;
d
Working Memory Task (total efficiency across task conditions due to no sex/dose effects on either condition).
