Electrophysiological markers of error processing.

Scalp topographies (top), grand averaged response-locked time courses (middle) and scatter plots showing associations with age (bottom) for the ERN (left) and Pe (right). Time courses are split between incongruent correct trials (blue), incongruent error trials (red) and the difference, or delta, between the two (orange). Data in the scatter plots are from incongruent trials and μV is here the mean voltage of a 40 ms time window surrounding each peak.
