Most right-handed people will choose the bottom picture, with the smile going up on the left. They are judging the face with their right hemisphere, if they are looking at the nose as instructed. In fact, with the focal point as a center, by tachistoscopic presentation (pictures flashed at one/tenth of a second), the bottom face always looks happier to right-handed people.

You can try this here by moving the page up and down fairly rapidly. At least the effect is very apparent for me, a right-hander.
