      abstract = {We validated the stop-signal task (Lappin & Eriksen, 1966)  in an online context with performance-based monetary bonus  to incentivize active participation. Our study modified the  current paradigm designed by Verbruggen, et al. (2019)  following suggestions from their consensus guidelines.  Stop-signal reaction time (SSRT), the primary measure from  the task, has been shown to correlate with trait measures  of impulsive personality to various degrees. Consistent  with previous literature, our preliminary analysis revealed  a strong correlation SSRT and two forms of impulsive  personality (motor & attentional) measured by Barrat  Impulsiveness Scale (BIS-11). Additionally, recent studies   found that short (< 200ms) stop-signal delays (SSD) are  more likely to result in violations of independence.  Therefore, we also conducted analysis excluding trials with  SSD less than 200ms according to their suggestions. Both  analyses demonstrate a link between stop-signal reaction  time (SSRT) and impulsive personality trait measured by the  BIS-11. Analyses excluding trials less than 200ms (N = 73)  found no significant correlation between attentional and  nonplanning measures of impulsivity, although a strong  correlation between SSRT and motor impulsivity (r = 0.39, p  < 0.001) is still present. The stop-signal task is a  promising tool awaiting further development and our  research suggests that by employing a financial incentive  to participate, the task can bridge the gap between  self-reported impulsive traits and task-based measures of  inhibitory failure.},
