#AUDIENCE APPLAUSE PROFESSIONAL#

We investigated how the coordination dynamics of a professional string quartet changed as they learned unfamiliar pieces together across eight trials. Often, harmonious interpersonal coordination requires learning, such as ensemble musicians rehearing together to synchronize their low‐level timing and high‐level aesthetic musical expressions. The ability to coordinate with others is fundamental for humans to achieve shared goals. The social contagion model arising from our analysis predicts that the time the audience spends clapping can vary considerably, even in the absence of any differences in the quality of the presentations they have heard. We also found consistent differences between individuals in their willingness to start and stop clapping. The cessation of applause is similarly socially mediated, but is to a lesser degree controlled by the reluctance of individuals to clap too many times.

Individuals' probability of starting clapping increased in proportion to the number of other audience members already 'infected' by this social contagion, regardless of their spatial proximity. We used Bayesian model selection to test between various hypotheses about the spread of a simple social behaviour, applause after an academic presentation.

A number of mathematical models have been hypothesized to describe these social contagion phenomena, but these models remain largely untested against empirical data.

Within a group, a new behaviour can emerge first in a few individuals before it spreads rapidly to all other members. The study of social identity and crowd psychology looks at how and why individual people change their behaviour in response to others.
