Go-RT = mean correct go reaction time; Failed stop RT = mean RT on failed stop trials; Overall SSD = mean stop signal delay in all stop trials; SSD after convergence = mean stop signal delay in stop trials after convergence; Response accuracy = % correct trials (stop and go trials); Go omission error = % omission error on go trials; probability of stopping after convergence = probability of stopping on stop trials after convergence; SSRT = mean stop signal reaction time (Go-RT – SSD after convergence), calculated for each subject then averaged. Data are presented as mean ± S.E.M.
