On the left in bold are the empirically observed (Emp.) stop-failure RTs, on the right the estimated (Est.) stop-failure RTs according to the third prediction. Stop-failure RTs were calculated on the basis of the go RTs distribution and by using the inhibition probability of the single SSDs. Underlined are the few cases for which the estimated stop-failure RT was longer than the observed one.
