N170 EEG results. A. N170 grand average time course over electrodes P7/P8 and PO9/PO10 for the different conditions. Horizontal (HEOG) and vertical (VEOG) electrooculogram activity is displayed in the upper part of the figure showing that eye movements were insignificant and did not differ across conditions. B. Mean N170 peak amplitudes for the different conditions. Data were normalized using the normalization method described in Franz and Loftus [60] to remove irrelevant between-subjects differences. Error bars denote standard error of the mean for the normalized scores (SEMnorm). C. Grand average topographies at N170 peak for the different conditions. Scaling is the same across all conditions. Note.*p < .05, ***p < .001.
