Fig. 2.

Event-related potentials (ERPs) (current source density) and topographic maps showing the flanker P1, flanker N1, target P1 and target N1 components during compatible and incompatible flanker trials for both groups. The time windows represented in the scalp topographies are stated in the methods section. Positive values are given in red, negative values are given in blue. Time point zero denotes the occurrence of the target stimulus. Negative values are plotted downwards.
