From: The developmental pattern of stimulus and response interference in a color-object Stroop task: an ERP study

Figure 5

Stimulus interference effects overlapping the negative (N4) and positive (P3) components (adults 260 – 400 ms; children 400 – 560 ms). Grand-averaged ERPs for congruent (C) and stimulus incongruent (SI) conditions at CPz in each of the four age groups. Topographical maps of the voltage difference for the SI minus C condition (blue: negative difference; red: positive difference) indicating stimulus interference show a negative amplitude difference (adults: 260–400 ms; children: 400–560 ms) reflecting the amplitude enhancement of the N4 component and the amplitude reduction of the P3-like component widely distributed over the scalp and most pronounced in 6–7 year-olds that decreases with age.
