Pages 540-561
Asymmetric facial expression is generally attributed to asymmetry in movement, but structural asymmetry in the face may also affect asymmetry of expression. Asymmetry in posed expressions was measured using image-based approaches in digitised sequences of facial expression in 55 individuals, N= 16 men, N= 39 women. Structural asymmetry (at neutral expression) was higher in men than women and accounted for. 54,. 62, and. 66 of the variance in asymmetry at peak expression for joy, anger, and disgust expressions, ...
