Clapping reveals applause is a 'social contagion'

The quality of a performance does not drive the amount of applause an audience gives, a study suggests.

Instead scientists have found that clapping is contagious, and the length of an ovation is influenced by how other members of the crowd behave.

They say it takes a few people to start clapping for applause to spread through a group, and then just one or two individuals to stop for it to die out.

The Swedish study is published in the Journal of the Royal Society Interface.

Lead author Dr Richard Mann, from the University of Uppsala, said: "You can get quite different lengths of applause - even if you have the same quality of performance. This is purely coming form the dynamics of the people in the crowd."

Chain reaction

The research was carried out by studying video footage of groups of undergraduates as they watched a presentation.

The scientists found that it took just one or two people to put their hands together for a ripple of applause to spread through the crowd.

These claps sparked a chain reaction, where, spurred on by the noise, other audience members joined in.

"The pressure comes from the volume of clapping in the room rather than what your neighbour sitting next to you is doing," explained Dr Mann.

But the performance that had been witnessed - no matter how brilliant - had little effect on the duration of the noisy acclaim.

In fact, the researchers found the duration of applause varied greatly.

Dr Mann told BBC News: "In one case an audience might clap on average 10 times per person. Another time they might clap three times as long.

"And all that comes from is that you have this social pressure to start (clapping), but once you've started there's an equally strong social pressure not to stop, until someone initiates that stopping."

The scientists believe that clapping is a form of "social contagion", which reveals how how ideas and actions gain and lose momentum.

Studying this, they say, could shed light on other areas, such as how trends come in and go out of fashion or how ideas spread on the internet.

Dr Mann said: "Here we tested whether you are more driven by the total number of people in the room or the people sitting next to you.

"And the equivalent on Facebook or Twitter would be whether you are more likely to join in a trend if you see lots of people in the wider world mentioning it or if just your closer friends mention it."

    I'm in a local amateur choral society, and we frequently get attenders who don't have experience of classical performances and clap in the wrong places. Thankfully the rest of the audience who do know don't follow on from these few, or we'd have chaos!

    I recently attended a performance which to be frank was awful and I did not applaud at any point. The audience almost to a "man" applauded despite this. I wanted to boo but my wife stopped me going that far.

    We left at the interval and complained to the staff but with no response.

    We are too polite..200 years ago the audience would throw things if they felt it was bad.

    Applause could be either genuine mark of praise or it could be simply politeness. Standing ovations are normally sincere, from the heart. However in certain totalitarian states, applause is orchestrated and here lies the rub! Spontaneous ovation is euphony to the ears. One needs to be honest when showing appreciation; otherwise one loses one's critical powers, sense of judgement. Life is short!

    It also depends who is in the audience. I have seen plays which are so, so but because friends and family are there, and those with a personal interest in the play's subject matter, they have clapped for a very long time. Longer than the play really deserves. Then I have watched brilliant plays, and the applause has not been so long due to it been made up mostly of strangers.

    I find this questionable to say the least. I have been in audiences where a number of other people and myself have found the performances poor and haven`t applauded, whilst many others did. I have also been in audiences where a number of other people and myself loved the performance and gave it a standing ovation and lengthy applause, whilst others stayed seated and didn`t applaud.
