A. Average ERP time waves for Black (green) and White (blue) at frontal electrode FC4, in the group of participants with IAT-Black scores higher than the median IAT-Black. The difference between Figure A and B in ERP amplitude is highlighted in Figure A. Participants with more negative associations to Black faces appear to have larger P200 to Black and larger N200 to White.
B. Average ERP time waves for Black and White at frontal electrode FC4, in the group of participants with IAT-Black scores lower than the median IAT-Black.
C. Scatter plot of the mean Black-White amplitude difference at around 228 ms over frontal scalp by IAT-Black for each participant, with a trend line added to show the correlation
D. Scatter plot of the mean Black-White amplitude difference at around 224 ms over temporal scalp by IAT-Black for each participant, with a trend line added to show the correlation.
Note: Correlations in the figures are the largest correlations in that time range. For median correlations, see Table 1.
