Grand-average waveforms of error trials (training-ERN signals, in blue), correct trials (in red) and training-ErrP signals (in black) at Cz electrode. The waveforms were smoothed out with a 25-Hz low-pass FIR filter, for an illustration purpose. Training-ErrP signal (in black) is the difference of the neural responses of error trials and correct trials. Green highlights show the time-points where the training-ErrP signal is significantly different against zero (p < 0.01, one-sample t test)
