Additional contrasts indicated that the CE in FSW amplitude was significantly smaller in alcohol group (M = −0.35 µV) compared to the average of the control and placebo groups (M = 0.56 µV), t(1969) = −2.04, p = .04, and that the CE in FSW amplitude was significantly smaller in the control group (M = 0.80 µV) compared to the average of the placebo and alcohol groups (M = −0.63 µV), t(1969) = −3.52, p < .001, indicating both pharmacological and expectancy effects on the FSW.
