Figure 3

The left panel shows the modulation of ERP activity induced by categorical perception. The waveforms represent the difference Wave (DW) calculated by subtracting the ERP activity elicited by standard faces (SC) from the one elicited by faces featuring other-race connotations (BC) for adults (black continuous line) and children (gray dashed line). The right panel displays the scalp localization of the DW in the two groups.
