participant, task and paradigm were shifted 2 samples (approximately +8 ms) so that the N1 sink maximum would match the respective mean N1 sink peak latency for words during the RM paradigm (approximately 149 ms). Local N1 sink maxima were unambiguously determined within these intervals in almost all instances (100% for words, 97.2% for faces); if not, the CSD waveforms were not shifted. The N1 sink latency shift did not significantly differ between AH, NH, and HC groups in either task or paradigm (overall range −51 to +31 ms; RM, F[2,92] = 1.48, p > .23; WM, F[2,109] < 1.0, n.s.).
