Abbreviations: BIS, scores on the behavioural inhibition questionnaire; Extr, EPQ extraversion; Go_RT, go reaction time on Go trials in ms; Med, intermediate; M/F, number of male and female participants per group; Neur, EPQ neuroticism; Pinhibit, probability of inhibition on Stop trials; SSRT, stop-signal reaction time (mean stop-signal delay on the intermediate staircase subtracted from median Go reaction time); SST, stop-signal task; STAI-T, Spielberger trait anxiety. There were no statistical differences between the groups.
