Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, examines laughter as a means of exploring mechanisms and evolution of vocal production, perception and social behavior. He examines laugh structure, compares human to chimp laughter, sociolinguistic contexts of laughter, the contagiousness of laughter, and pinpoints directions for future study. This article, originally printed in American Scientist 84. 1 (Jan-Feb, 1996): 38-47, is a more in-depth, scholarly article than the other, related article on laughter that I posted: Provine's "The Science of Laughter."

Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, summarizes a decade's worth of research in this article. He concludes that laughter is primarily a social vocalization that binds people together. It is a hidden language that we all speak. It is not a learned group reaction but an instinctive behavior programmed by our genes. Laughter bonds us through humor and play. He also explores gender differences in regard to the role of laughter in communication, also laughter as a tool in romance/pair-bonding.

Laughter is primal, our first form of communication. Scientist believe that laughter is mainly a social response oppose to a response to a joke.

It takes just one-tenth of a second for our brains to begin to recognize emotions conveyed by vocalizations; apparently human brains pay more attention when emotions are embedded in vocalizations rather than in speech. Participants were able to detect vocalizations of happiness (i.e., laughter) more quickly than vocal sounds conveying either anger or sadness. Vocalizations displaying anger, however, are more resonant than those displaying other emotions: both produced ongoing brain activity that lasted longer than either of the other emotions: "listeners engage in sustained monitoring of angry voices, irrespective of the form they take, to grasp the significance of potentially threatening events." More anxious individuals also have a faster and more heightened response to emotional voices in general than people who are less anxious.
