Why we laugh

Did you know that you’re 30 times more likely to laugh if you’re with somebody else than if you’re alone? Cognitive neuroscientist Sophie Scott shares this and other surprising facts about laughter in this fast-paced, action-packed and, yes, hilarious dash through the science of cracking up.

As deputy director of the University College London’s Institute of Cognitive Neuroscience, Sophie Scott seeks out the neurological basis of communication, whether it’s speech or vocalized emotion.

As a pioneering researcher in the science of laughter, she’s made some unexpected discoveries — including that rats are ticklish, and that the one tactic that’s almost guaranteed to get someone to laugh is to show them someone else laughing. But as an occasional stand-up comedian with UCL’s Bright Club, she shows that she’s no slouch at getting laughs herself.

It’s a fast-paced romp through the various theories of laughter which is, after all, a very extraordinary characteristic that we humans enjoy.
