Module Aims Bayesian approaches have made important contributions to Behavioural Science, both as statistical models for empirical data, and as cognitive models of how people perform tasks. As statistical models, Bayesian methods are particularly important for establishing the absence of an effect, which is difficult for standard statistical methods to do. As cognitive models, Bayesian methods prescribe what an agent should do in a task, as as such provide important benchmarks against which to compare human behaviour. In both domains, approximations play an important role: allowing the practical use of complex statistical models, and providing a route to explain deviations of human and animal behaviour from the Bayesian ideal. The purpose of the module is to introduce Bayesian approaches to statistics and modelling of behaviour, and the approximations that make them work in practice. |
