In an article published October 31 on Vox.com, Psychology Professor Robert Provine was quoted extensively about his research on hiccups and the evolution of behavior. He discussed how there’s little scientific knowledge about hiccups and how they are difficult to study.

“We still don’t know what hiccups do, and our cure for them hasn’t improved since Plato,” said Provine. “You can’t just go into the lab and ask someone to hiccup for you.”

Provine also discussed holding breath as a possible cure for intractable hiccups. “You’re blocking the motor pattern as well as leading to a buildup of carbon dioxide,” he said.

In an article published on Today.com discussing a recent episode of “The Tonight Show” in which Bradley Cooper and Jimmy Fallon couldn’t control their laughter throughout a ten-minute interview, Provine was quoted from a 2010 interview he participated in with NBC News.

“All laughter is unconscious,” he said. “You do not choose to laugh the way you choose to speak.” The article also cites Provine by stating: “And laughter and humor aren’t as closely tied as people might think. Babies laugh without understanding a joke or that knowing that pratfalls are hilarious, according to Provine.”
