Learning positive social information reduces racial bias as indexed by N400 response.

P300 response (500–600 ms) The ANOVA performed on the P300 amplitude values, measured between 500 and 600 ms over the anterior-frontal sites (AFF1, AFF2, AFZ, FZ and FCZ) showed a borderline significant main effect of condition (F (2, 68) = 3.14, p = 0.05; η p 2 = 0.08), indicating that the P300 amplitude recorded in response to Congruent terminal words (4.18 μV, SE = 0.51) was overall greater (p = 0.015) than the one measured in response to Neutral terminal words (3.41 μV, SE = 0.53).
