Psychology Professor Robert Provine appeared in the July 2014 edition of Real Simple magazine in an article about the evolution and science of laughter. The magazine published a lengthy article in the print edition and also posted a version of the article on its website.
In the print version, Provine said that more research is needed, but it’s probable that those who laugh easily and often are happier than those who don’t. Laughter is “the sound of play,” he said. “So our brain automatically associates it with carefree interactions with friends, family and lovers.”
The article also cites one of Provine’s earliest research experiments in which he found that just listening to recorded laughter can often evoke fits of giggles. According to his research, you’re 30 times more likely to laugh when someone else is around than when you’re by yourself. “It’s highly contagious,” he said.
