Each participant rated 50 one-word audio recordings (“hi”) on a 1–7 scale for one of four social attributes (competence, trustworthiness, dominance, or attractiveness).Main Outcome Measures:Perceived competence, trustworthiness, dominance, and attractiveness of voice samples, rated on a 7-point Likert scale.
