Figure 2.
Face-categorization responses characterized in the frequency domain across conditions (Experiment 1), in the form of baseline-subtracted amplitude spectra. Face-selective responses were tagged at F (= 1 Hz) in every condition, with higher harmonics occurring at 2F (2 Hz), 3F (3 Hz), etc. (only the first two harmonics are labeled above the spectra). The data are shown over the region of the scalp failateral occipito-temporal ROI) andfrequency range (up to 20 Hz) that were selected to capture face-selective responses. Higher harmonio frequencies coinciding with stimulus-presentation harmonio frequencies are drawn in very light yellow, and may surpass the plotted amplitude range. For ease of comparison across conditions, all graphs are plotted with common axes.
