A new study has found that people experience the most positive emotional reactions when they hear spontaneous, open-mouthed laughter, especially if the laughter comes from a woman.
The finding adds to a growing understanding of how laughing functions as a deeply-rooted form of unconscious communication between people, a topic that Robert Provine, professor of psychology, has studied extensively. He points out that laughter has roots that precede humanity.
