Figure 2. Averaged ERP waveforms elicited by images of unfamiliar and familiar conspecific faces as well as the subject’s own face in Experiment 1.

The blue-shaded squares overlaid on the waveforms show the periods of statistically significant main effects of stimulus category. The solid lines below the waveforms show the periods of significant difference between unfamiliar and familiar (green) and unfamiliar and self (orange) images.
