Ambiguous at the second sight: Mixed facial expressions trigger late electrophysiological responses linked to lower social impressions.

ABSTRACT: Social interactions require quick perception, interpretation, and categorization of faces, with facial features offering cues to emotions, intentions, and traits. Importantly, reactions to faces depend not only on their features but also on their processing fluency, with disfluent faces suffering social devaluation.
