Conclusion

The influence of smile type appeared to be stronger for the ratings of extroversion and generosity.

  • Male faces were rated by men as being significantly more generous when showing a Duchenne smile.
  • The effects of Duchenne smile on ratings of competitiveness and conscientiousness were low and moderate (they increase due to smiling).

  • Low effect sizes were also observed for the judgements of agreeableness, openness to experience, and neuroticism.

  • Smiles with an emotional basis (Duchenne smiles) are affecting the judgements of personality traits (extroversion and generosity)
  • Ratings of generosity given by female judges to male smiling faces were slightly affected by smile type.

  • Duchenne smile - signal of sociability
