Individuals were more likely to start clapping if a larger percentage of the audience had already started, Mann's group reports online today in the Journal of the Royal Society Interface. Then the team took the videos back to the lab and analyzed them.Īpplause, it turns out, is a bit like peer pressure. He and colleagues filmed groups of 13 to 20 students at the University of Leeds who were clapping after a number of different oral presentations by undergraduate and postgraduate students. But researchers didn't fully understand the dynamics of what happens in the audience.Įnter Richard Mann, a mathematician at Uppsala University in Sweden.
