The transferable belief model in film and games studies

This post is another draft paper, this time focusing on the difference between ergodic and non-ergodic texts and so is of relevance to games studies as well as film studies. I use an approach that I don’t think has been applied to either of fields yet: the transferable belief model, which is a mathematical theory of evidence. Hopefully soon I will be able to outline how this model will be of use in film studies in more depth, along with considering its relationship to Bayesian approaches to modelling viewer behaviour. The idea is to apply these models to the empirical analysis of the beliefs of real spectators so that it may be possible to make some statements about how we understand films that are more than theoretical but which have a solid evidential basis. The article can be downloaded as a pdf file here:Nick Redfern – Credal and pignistic reasoning in ergodic and non-ergodic texts.

Abstract

This paper discusses the difference between ergodic and non-ergodic texts by considering the different levels of reasoning required of an agent in each case. The difference indentified between such texts is based on the distinction between credal and pignistic reasoning in the transferable belief model. It is argued that non-ergodic texts require an active agent to reason about the state of the world, and thus operate at the credal level; while ergodic texts require that the belief function of an agent be transformed into a probability function for the purposes of decision making, and therefore entail both credal and pignistic reasoning. The difference between ergodic and non-ergodic texts considered in these terms is illustrated through comparing narratives from the CSI: Crime Scene Investigation franchise.

About Nick Redfern

I graduated from the University of Kent in 1998 with a degree in Film Studies and History, and was awarded an MA by the same institution in 2002. I received my Ph.D. from Manchester Metropolitan University in 2006 for a thesis title 'Regionalism and the Cinema in the United Kingdom, 1992 to 2002.' I have taught at Manchester Metropolitan University and the University of Central Lancashire. My research interests include regional film cultures and industries in the United Kingdom; cognition and communication in the cinema; anxiety in contemporary Hollywood cinema; cinemetrics; and film style and film form. My work has been published in Entertext, the International Journal of Regional and Local Studies, the New Review of Film and Television Studies, Cyfrwng: Media Wales Journal, and the Journal of British Cinema and Television.
