Table displays significant post-hoc comparisons (paired t-tests) for dynamic facial expressions including the different time windows (ms), ERP-component (LPP), the kind of comparison (neu = neutral, hap = happy, dis = disgusted), electrode site, T-values, degree of freedom (df), and p-values (p-values highligted in bold remain significant after FDR correction). Grey and italic font represents additional electrodes of interests (see methods for further explanations).
