from Part II - Human Behaviour
Published online by Cambridge University Press: 29 May 2026
The use of Bayesian modelling has been growing in the cognitive sciences, as it provides a flexible framework for modelling complex and heterogeneous data, as well as incorporating prior knowledge and uncertainty into the modelling process. In this chapter, we focus on predictive Bayesian modelling, which allows for the construction of models that can make accurate and meaningful predictions about future events, behaviours or outcomes. We begin by providing a brief overview of Bayesian statistics and the key concepts necessary for understanding predictive Bayesian modelling. We then discuss the benefits and limitations of using predictive Bayesian modelling in cognitive science research. Next, we explore several examples of how predictive Bayesian modelling has been applied to different areas of cognitive science, including perception, memory, decision-making and language. We discuss how these models have contributed to our understanding of cognitive processes and how they can be used to make predictions about human behaviour. Finally, we outline some of the challenges and future directions for predictive Bayesian modelling in cognitive science research. We discuss the importance of evaluating model fit and model comparison, the need for more accurate and informative prior distributions and the potential for combining predictive Bayesian modelling with other methods, such as machine learning.
