EEG results reflecting online statistical learning: ITC (mean of six centrofrontal midline electrodes, FC1, FC2, F3, F4, FC5, and Fz) during exposure to random and structured sequences in experiment 1 (TMS) and experiment 2 (Cognitive Load). Topographical plot shows distribution of ITC across the scalp, as a function of exposure and frequency. ITC values were used to calculate the WLI (i.e., ITC word / ITC syllable) (Fig. 3).
