ERP-Agreeableness regression results for the entire sample. (a) Raster plot depicting significant channels and time-points for the agreeableness regression colored based on their F values. On the right the topographical representation of the F values averaged across the significant time-window (191–227 ms) highlighting the scalp regions where significant effects were observed; the larger black circles on the topographic plot represent the electrodes that formed the significant clusters. (b) Scatterplots representing the correlation between the beta contrast values averaged across the significant time window and the agreeableness trait, separately for the two clusters. (c) Trace plots showing the mean beta values for the social (in blue) and non-social conditions (in orange) averaged over the significant electrodes from each of the two clusters, separately for the high A and low A group.
