Event‐related brain potentials (ERPs) were used in two experiments to examine the neural correlates of processes underlying task switching in the information‐reduction task switching paradigm. Each experiment included 22 participants. The paradigm included two cues for each task. This element of the design allowed us to differentiate the ERP correlates of cue retrieval, task set reconfiguration, and rule mapping. The ERP data revealed a parietal slow wave that was sensitive to processes associated with cue retrieval and task set reconfiguration and a frontal‐polar slow wave that was sensitive to processes associated with rule mapping. These findings further the proposal that an endogenous act of control supporting processes related to task set reconfiguration and rule mapping may facilitate performance of the explicit cue task switching paradigm.
