Faces, Emotions, and “Handedness”

Most women instinctively clasp babies to their left side. Researchers have all sorts of guesses why, ranging from dominant right-handedness to the beating of the heart. New research, however, suggests it has do with how we processes faces, and which side of our brain handles emotion.

To see how your own brain deals with faces and emotions, today’s Nature has the following test: Which face do you think is happiest? Check below to find out what your answer means.

The faces are symmetrical. So if you think B looks happiest than that means you use the right side of your brain to process faces; if you think A looks happiest then you use the left side of your brain to process faces.
