Anyone whos has systematically examined faces will have perceived a prepondreance although not a proliferation of asymmtry.whether or not the expression is volitinal and self controlled or spontaneous appears to predict facial asymmetry as does the type of emotion protrayed.positive emotions are usually displayed symmetrically although a left sided representation of a negative emotion is more common.posed expressions and
negative emotions are less likely to be symmetrically represented.
1. An angry person is more likely to have a lopsided expression than some one who is smiling
2. A deliberately assumed facial expression will always be asymmetrical
3. An actor is likely to smile symmetrically when acting
4. More self conscious people are likely to have less asymmetrically facial expressions than those who are less aware of themselves
