Dress for success: human facial expressions are important signals of emotions

摘要

In order to test how emotions affect individual neutral facial expressions and the reliability of humans to read these expressions, we photographed faces of 25 women wearing clothes in which they felt attractive, unattractive, or comfortable while expressing an emotionally neutral face. Men found the faces of women in attractive clothes the most attractive, whereas the faces of women in comfortable and unattractive clothes were ranked as intermediate and least attractive, respectively, even though the clothes were not visible in the photographs. Our results demonstrate that despite very subtle effects, the emotional state of women is perceived by men and that the two sexes are concordant on the signal sent and received. We show a close connection between exterior attributes, confidence, and how a person is perceived by others.
