Mean CSD-transformed ERP waveforms in the scrambled and comprehension conditions. (A) CSD-transformed ERP waveforms (in μV/cm²) at each of 64 scalp sites time-locked to the onset of the target word (“and”) in the scrambled condition (blue) and the comprehension condition (red) for all participants (N = 28). Current sources are plotted as positive values, and current sinks as negative values. (B) CSD-transformed ERP waveforms at scalp site AFz for all participants. (C,D) CSD-transformed ERP waveforms for good comprehenders (N = 15) at all scalp sites (C) and at AFz (D). (E,F) CSD-transformed ERP waveforms for poor comprehenders (N = 13) at all scalp sites (E) and at AFz (F). The corresponding waveforms without CSD transformation are shown in Figure A1.
