RT data satisfy race model assumptions. A, RTs were faster in stopFail trials compared with Go trials for both the Uninformed and Informed condition. We further observed that noStop trials were faster than Go trials in both Information conditions, indicative of strategic slowing. B, StopFail RT increased linearly with SSD, as predicted by the independent race model. C, The ZRFT indicates the finishing time of a Stop and Go process, with higher values indicating a late finishing time for the stop process relative to the go process. Each participant is represented by a thin gray line. A cumulative Gaussian was fit for each participant, and the bold black lines were generated by averaging parameter fits over participants. Both Uninformed (left) and Informed (right) conditions show that as ZRFT increases, the probability of stopFail increases. When the ZRFT is 0 the probability of stopSuccess and stopFail was close to 0.5, as predicted by the independent race model. Error bars indicate SEM.
