Behavioral Measure.
Face Ratings Task. Following the EEG session participants
completed a ratings task in which they rated the 6 faces presented in
the oddball task for valence and arousal. Valence and arousal were rated
on a Likert scale from -4 (Very Negative/ Not at all) to +4 (Very
Positive/Extremely). Participants were told to indicate how positive or
negative they perceived each face (valence) and how strongly they felt
that emotion (arousal) (Supplementary Figure 1).
