We examined asymmetry in posed facial expression of emotions: happy and sad. Hemifacial composite photographs, left-left and right-right, were prepared, and subjects rated these for intensity of expressed emotion. Overall, left-left composites were judged to have expressed emotions relatively more i...

Description
Summary:We examined asymmetry in posed facial expression of emotions: happy and sad. Hemifacial composite photographs, left-left and right-right, were prepared, and subjects rated these for intensity of expressed emotion. Overall, left-left composites were judged to have expressed emotions relatively more intensely than the right-right composites. The significant Sex x Emotion interaction revealed that female expressors were judged as more expressive than male expressors in expressing sad facial emotion. Sex difference in expression of happy facial emotion was not significant.
