Rutge's William Brown and Robert Trivers led a study in which they measured the degree of body symmetry in children and its correlation in their lives.
They found out several interesting things:
- Jamaican girls and women are more likely to cradle dolls and babies, respectively, on their left side of the body if their ears are symmetrical.
We interpret these results as making sense because information going into the left ear (and left visual field) go immediately to the right half of the brain, which is specialized for interpreting emotional information (such as is conveyed in a baby?s voice and actions).
- Girls that are more symmetric are more attractive
- Lower dermatoglyphic asymmetry (whatever it is) tracks with academic achievement
And, this just in:
- Symmetric people are better dancers!
The new study involved 183 Jamaican teenagers, ranging between 14-19 years old, who danced while their movements were captured using motion-capture cameras similar to those used in video games and movies to give computer-generated characters fluid movements.
Women watching the recordings preferred the dances of men who were more symmetrical, while men were more impressed by the dances of more symmetric females.
