Is laughter contagious?
Have you ever noticed how you tend to smile if you hear other people laughing? Or how you laugh a lot more at a film in a cinema full of people than if you were alone?
Well it seems we are indeed hard-wired to laugh along with the people around us.
In 2006 a team of researchers from University College London found that, whenever test subjects were played the sound of someone laughing, it triggered the automatic response of a smile or laugh.
The results for laughter were much stronger than those recorded when the subjects were played other sounds, for example, people didn’t start shrieking if they heard screams.
