Mean N2 amplitudes and standard deviations (SD) reported separately by Emotion and Race, across electrode positions: left, medial, right (LMR) and anterior, anterior-central, and posterior-central regions. Bold numbers represent descriptive statistics for significant effects of Race, italicized numbers represent descriptive statistics for non-significant effects of race
