The role of structural facial asymmetry in asymmetry of peak facial expressions

摘要: Asymmetric facial expression is generally attributed to asymmetry in movement, but structural the face may also affect of expression. Asymmetry posed expressions was measured using image-based approaches digitised sequences 55 individuals, N=16 men, N=39 women. Structural (at neutral expression) higher men than women and accounted for .54, .62, .66 variance at peak joy, anger, disgust expressions, respectively. Movement (measured by change pixel values over time) found, unrelated joy or anger whole subregions relevant negatively related expressions. Sidedness movement (defined as ratio summed on left right) consistent across emotions within individuals. found only joy...
