Emotions Are Expressed More Strongly on Left Side of Face
In my biopsychology class for the topic of emotions, one of the things that I learned is that the right hemisphere of brain processes emotions more than left. And I learned that this shows when the left side of face expresses emotions more strongly than the right (Right Hemisphere controls Left Side of Body).
Digging further into the fact, I found a study that shows this. The study found random photos of faces, took the left side and right side and made individual face composites of each side. What the researchers did is cut the face picture in halves, take the right side, duplicate it and merged it together to create a full face. They did this for the left side as well. Then to determined whether the left or right side expresses emotions more strongly, the researchers had participants judge the composites of left vs right photos. As supported by the study, the left side of face, controlled by the right hemisphere, was judged to have stronger emotional expressions than the left.
