Grand average of ERPs recorded in CR and PDW tasks at parietal electrodes (CPz, Pz) in response to neutral (black lines) and fearful faces (red lines)–left panel.

<p>Responses obtained in “unaware” (thin lines) and “aware” trails (thick lines) are also shown. The right panel shows difference waves computed as a difference between aware and unaware conditions recorded in CR and PDW tasks at parietal electrodes (CPz, Pz) in response to neutral (black lines) and fearful faces (red lines). Time windows for the region of interest (P3 component; 300–400 ms post-stimulus) are highlighted at corresponding electrodes; time 0 indicates stimulus onset.
