Figure 1.
Grand average difference waveform: No-Go – Go trials.
Figure 1 presents the grand average difference waveforms (i.e., average of all trials, across all participants) of the No-Go minus Go trials for electrodes Fz, Cz, and Pz. Note: we use the grand average difference waveforms for this figure as this is more informative compared to separate waveforms of No-Go correct trials and Go correct trials. However, in further analysis we took the amplitude for correct No-Go trials N2 and P3 at the midline electrodes Fz, Cz and Pz as the variables of interest.

Correct No-Go N2 and P3– Internal consistency analysis.
Figure 2 presents (A) the average N2 and P3, (B) Pearson's correlations, and (C) Cronbach's alpha as progressively more trials are included in the participants' average, all for the three midline electrodes Fz (left), Cz (middle), and Pz (right). The average presented in this figure refers to the grand average (all trials and all participants).
Figure 3.
Grand average difference waveform: error - correct trials.
Figure 3 presents the grand average difference waveforms (i.e., average of all trials, across all participants) of the error minus correct trials in the Eriksen Flanker task. Note: we use the grand average difference waveforms for this figure as this is more informative compared to separate waveforms of error and correct trials. However, in further analysis we took the amplitude for ERN (at FCz) and Pe (at Pz) error trials as the variables of interest.
Figure 4.
Error trials – Internal consistency analysis.
Figure 4 presents the (A) average ERN and Pe, (B) Pearson's correlations, and (C) Cronbach's alpha as progressively more trials are included in the participants' average, for the ERN (at FCz) and Pe (at Pz). The average presented in this figure refers to the grand average (all trials and all participants).
