Attractiveness, individual subjective attractiveness judgments; formula, model definition for the lme4 software package; RE, random effects structure [(1| Participant) + (1| Stimulus)]. GI = [Participant Sex × Face Gender]. EGI = [Participant Sex × Participant Eye Color × Face Gender × Face Eye Color].
