Not without reason that Leonardo da Vinci chose the left side of face in his famous painting, Mona Lisa. Recent psychological research suggests the left side of the face look more fun than the right side. 

Human emotions can be read from the look on his face. The muscles of the face designed to be easy to show expressions that represent a variety of feelings. Of all muscles in the face, left side muscle is more expressive. 

Research conducted by two psychologists, Kelsey Blackburn and James Schirillo, from Wake Forest University, the United States confirmed this concept. The results are published online in the journal Experimental Brain Research. "Appears the left cheek bone reveals the intensity of emotions that are considered more aesthetic," says Blackburn. 

Experiments that involve volunteers and a stack of photographs of human faces. Volunteers were asked to rate the beauty of the left and right faces of women and men. Every face in the photo is divided into two, namely the left and right. The result is then reflected in two new photos. The photos were displayed in black and white. 

When the assessment is collected, the researchers found a pattern that is very convincing. Volunteers showed great interest in the left side of the face, "he said. Interest in the left side of the face also explain why the portrait painter faces more highlight left side of the face. 

More confirmation comes from the examination of pupils. During the photo's face, dilated pupils when he saw the left side of the face. Pupil dilation has long been associated with pleasure. 

According to Blackburn, the research they are doing well in line with the concept of right brain dominance on the expression of emotion as well as the muscles controlling the left. *** [SCIENCEDAILY | ANTON WILLIAM | KORAN TEMPO 3862]
