The Dynamics of Audience Applause

Richard P. Mann, Jolyon Faria, David J. T. Sumpter, Jens Krause 2013

Sammanfattning:

The study of social identity and crowd psychology looks at how and why individual people change their behaviour in response to others. Within a group a new behaviour can emerge first in a few individuals before it spreads rapidly to all other members. A number of mathematical models have been hypothesised to describe these social contagion' phenomena, but these models remain largely untested against empirical data. We used Bayesian model selection to test between various hypotheses about the spread of a simple social behaviour, applause after an academic presentation.

Individuals' probability of starting clapping increased in proportion to the number of other audience members already 'infected' by this social contagion, regardsless of their spatial proximity. The cessation of applause is similarly socially mediated, but is to alesser degree controlled by the reluctance of individuals to clap too many times. We also found consisent differences between individuals in their willingness to start and stop clapping. The social contagion model arising from our analysis predicts that the time an audience spends clapping can vary considerably, even in the absence of any differences in the quality of the presentations they have heard.
