<P> Facial symmetry has been shown to have an effect of ratings of attractiveness in human faces . More symmetrical faces are perceived as more attractive in both males and females, although facial symmetry plays a larger role in judgments of attractiveness concerning female faces . A wide variety of methods have been used to examine the claim that facial symmetry plays a role in judgments of beauty . </P> <P> Blending of multiple faces to create a composite and face - half mirroring have been among the techniques used . While studies employing the first method produced results that indicate that more symmetrical faces are perceived as more attractive, studies applying the later method have indicated that humans prefer slight asymmetry . Also studies show that nearly symmetrical faces are considered highly attractive compared to unsymmetrical ones, yet more specifically, people tend to find a face unattractive if a person has an unsymmetrical nose, and effect of unsymmetrical lips do not really affect people on judging attractiveness . </P> <P> The most conspicuous directional asymmetries are sometimes only temporary . For example, during speech, most people (76%) tend to express greater amplitude of movement on the right side of their mouth . This is most likely caused by the uneven strengths of contralateral neural connections between the left hemisphere of the brain (linguistic localization) and the right side of the face . </P> <P> Conclusions derived from face mirroring, however, have been called into question, because it has been shown that mirroring face - halves creates artificial features . For example, if the nose of an individual is slightly bent to the right side, then mirroring the right side of the face will lead to an over-sized nose, while mirroring the left side will lead to an unnaturally small nose . </P>
