Figure 4. Mean amplitudes from the test phase depicting recognition-related brain activation for “recollected” and “familiar” old faces and correctly rejected new in-group and out-group faces for subjects with and without a behavioral in-group memory advantage.

Vertical lines highlight the time segment from 300 to 500 ms used for statistical analysis of the FN400 old/new effect. See Figure 1 for abbreviations of regions of interest and their locations.
