  1. These data pertain to the participants included in the behavioral analyses. N, number of participants; M/F, males/females; Go RT, reaction time on Go trials; Stop RT, reaction time on Failed Stop trials; SSD, stop signal delay; pOmisssion, probability of go omissions (no response); pCommission, probability of commission on Stop trials; a, Mean (standard deviation), unless otherwise indicated; b, Paired t-test; c, χ2 test; d, Wilcoxon signed-rank test.
