Post-error slowing in Experiment 1 data and in the models of Cho et al. (2002), Jones et al. (2002), Gao (first model; Gao et al., 2009), and the adapted DDM of the present study. In the Experiment 1 data, the mean RT for a trial immediately following the error trial is slower than that for the trial before the error, and the mean RT for the error trial itself is fast. The Cho and Gao models fail to account for both trends. The Jones Model accounts for the proper trends but overestimates the magnitude of the post-error slowing. The adapted DDM accounts for both trends but underestimates post-error RTs.
