Figure 3.

The S-cluster data (A) pooled across electrodes P7, P8, P9, and P10 with topographic plots for the incongruent condition separate for nonspeedup (non) and postspeedup (post) trials for each time window at the bottom and (B) at electrode Cz with topographic plots for nonspeedup (non) and postspeedup (post) trials in the congruent (con) and incongruent (ico) condition at the bottom. The congruent condition is shown in blue, the incongruent condition in red. The nonspeedup condition is shown in lighter coloring than the postspeedup condition. Time point 0 denotes the time point of the flanker stimulus onset. Time windows used for analyses are highlighted in gray. Topographic plots show the distribution of the potentials at the peak of the respective component. Positive potentials are shown in red, negative potentials are shown in blue, scaling is given in μV/m². The graph in (C) shows the interaction of Congruency*PostSpeedup on the first peak of the N2 complex. The sLORETA plots in (D) show BA6 as well as BA31 being differentially modulated at the first peak in the N2 time window in the incongruent condition (postspeedup > nonspeedup). For the sLORETA plots, heightened activation is shown in yellow, reduced activation is shown in blue, scaling corresponds to t-values.
