The alcohol‐exposed group consisted of 75 subjects, and the control group was 64 subjects; as not all subjects had valid measurements for each variable, actual subject numbers are given in left column for each variable (n alcohol‐exposed, n control).

For gender and handedness, the nonparametric Mann–Whitney U test statistic was used.
