Stop-signal reaction time (SSRT) can be computed according to one of the following methods: - integration method of the independent race model (Logan & Cowan, Psych Rev, 1984) - mean method (Logan & Cowan, Psych Rev, 1984) - modified integration method ()

Integration method ———————————————————- - Compute probability of responding given a stop-signal across delays (staircase) or for each delay separately (no staircase) - Estimate finishing time: integrate the no-signal response time distribution up to the point corresponding to the probability of responding given a stop-signal - Subtract mean delay (staircase) or delay (no staircase)
Mean method —————————————————————– - Compute probability of responding given a stop-signal across delays (staircase) or for each delay separately (no staircase) - Estimate finishing time: mean no-signal response time
Modified integration method ————————————————- - Compute probability of responding
