Beauty trends come and go, but one iron law of psychology remains: People with symmetrical faces are considered, by study subjects, to be more attractive. For years, the prevailing theory has been that this is because we use symmetry as a proxy for health , and thus, good genes. Supposedly, these minuscule changes later warn potential suitors—likely subconsciously—to stay away. The result? The more symmetrical teens weren't necessarily the healthiest ones.
Asymmetrical Face: What Is It, and Should You Be Concerned?
Asymmetrical Face: Causes, Treatments, and More
Please take this quick survey to tell us about what happens after you publish a paper. The Psychological Record. The first experiment investigated attributions to resting asymmetrical faces of 20 normal healthy young adults versus their symmetrical hemifacial composites. The second experiment used the same procedure with 24 expressive faces. Moreover, it is suggested that observers are not tuned to notice mild facial symmetry, and thus it does not affect attributions.
Facial symmetry is one specific measure of bodily asymmetry. Along with traits such as averageness and youthfulness it influences judgments of aesthetic traits of physical attractiveness and beauty. Facial symmetry has been suggested as a possible physical manifestation of the 'big-five' personality traits. Facial bilateral symmetry is measured via fluctuating asymmetry of the face comparing random differences in facial features of the two sides of the face that develop and accumulate throughout one's lifetime as a result of stressors. Facial symmetry has been shown to have an effect on ratings of attractiveness in human faces.
The term "asymmetry" is used to make reference to dissimilarity between homologous elements, altering the balance between structures. Facial asymmetry is common in the overall population and is often presented subclinically. Nevertheless, on occasion, significant facial asymmetry results not only in functional, but also esthetic issues. Under these conditions, its etiology should be carefully investigated in order to achieve an adequate treatment plan.
