Left side of the face looks more attractive; Research

Left side of the face of baby

Researchers have found that left side of the face is more attractive than the right side.

This research has been done by researchers from Wake Forest University and is going to be published online in the journal Experimental Brain Research.

[hana-code-insert name=’StumbleUpon’ /][hana-code-insert name=’Reddit’ /]Researchers have found that the left side of the face is able to show more emotions and better expressions, and is therefore looks more pleasant to the people. It has been reported that the same thing is utilized by Western artists in the portraits.

Researchers have showed the participants black-and-white profile photos. Some of them were original while the others were mirror reversed images. Participants were allowed to rate both the sides of the faces. Researchers have found that the left sides of the men’s and women’s faces got more ratings. This was true for the original photos as well as mirror-reversed images.

“Our results suggest that posers’ left cheeks tend to exhibit a greater intensity of emotion, which observers find more aesthetically pleasing,” study authors Kelsey Blackburn and James Schirillo, of Wake Forest University, wrote in a journal news release. The new findings support “the notions of lateralized emotion and right hemispheric dominance with the right side of the brain controlling the left side of the face during emotional expression,” they added.

Researchers thought that the change in pupil sizes in response to interesting stimuli is important in ratings. The researchers have confirmed their findings by measuring the participants’ pupil sizes. They found that the pupil size increases with attractiveness ratings.
