Fig 6. Experiment 1: Mean RTs and SE for congruency as a function of previous congruency between sessions in the positive manipulation (detailed data extending Fig. 5).

The maladaptive pattern of sequential analysis was present before the manipulation (Simon effect was significant after both congruent and incongruent trials), while an adaptive pattern of sequential analysis was present after the positive manipulation (Simon effect was significant after congruent, but not after incongruent, trials.
