Modelling narrative comprehension in film studies

In an essay titled ‘Can scientific models of theorizing help film studies’, Malcolm Turvey (2005: 25) asks why ‘is there a lack of systematic empirical research in film theory if the explanatory principles governing the cinema are like the explanatory principles governing natural phenomena?’

Turvey’s answer is that theories in the humanities do not need empirical validation in the same way as a theory in the sciences because ‘cinema is a human creation’ and is ’embedded in human practices and institutions,’ and researchers do not need to empirically validate their theory because they already know a great deal about such practices and institutions. Humanistic theories clarify our knowledge about things we already know, whereas scientific theories are generate new knowledge about subjects we have no prior knowledge about.

One of the examples of just such a humanistic theory accepted without validation cited by Turvey is David Bordwell’s (1985) constructivist account of the viewer’s comprehension of narrative. However, empirical research on narrative comprehension is to be found sociology, psychology, linguistics, and many other disciplines; but this is not the case in film studies. It is not because there is something special about film theories that means they do not require empirical validation – it is simply because no one has ever tried. Turvey does not address the fundamental reason for the lack empirical research in film studies: namely, that the vast majority of film scholars simply do not know how to design and conduct a piece of empirical research. There is a lack of basic empirical research skills in film studies, but this is unsurprising given that theory courses dominate film degrees while empirically based courses are few and far between. It is of course important that students study theory, if only so that they may have an understanding of the history of film studies as an academic discipline; but this should be accompanied with an emphasis on empirical research. Until this is generally the case, empirical validation of film theories will not be achieved.

We may have not trouble understanding a narrative film, but there are many questions about narrative comprehension in the cinema that can only be addressed through empirical research, including:

  • Which pieces of evidence in a narrative do viewer’s consider salient?
  • What hypotheses do viewers form to explain narrative events, and what role do they play in creating expectations?
  • How do different viewers weight the same piece of evidence in their reasoning, and why do they differ?
  • To what extent is the weighting of evidence determined by regimes of generic and cultural verisimilitude?
  • Is the viewer sceptical, withholding belief until the end of a narrative when its conclusion becomes apparent; or is she credulous, committing belief early on in a narrative only for her assumptions to be overturned?
  • What impact does the way in which evidence is presented to viewer have on her belief? For example, does it make a difference if a piece of evidence is presented visually with accompanying dialogue from a character, if it is presented visually only, or if it is presented as dialogue only?
  • Does the viewer strive to achieve the local or global coherence of a narrative?
  • Does the viewer make inferences that are unnecessary to the successful comprehension of the narrative?

Although we have no problem in understanding narratives, we do not have answers to these questions. If, as Turvey claims, film theories concern ‘what human beings already know and do‘ (25), it begs the question how do we know what human beings already know and do? How could we determine what human beings already know and do if we do not research (empirically) what it is that human beings know and do? We do not have answers to the above questions because no one has done the research, not because humanistic theories can be accepted without empirical validation. As the reader will soon learn, the plausibility of a theory is the not the same as truth.

In order to conduct research into narrative comprehension in the cinema we need some methods that will allow us to model the reasoning of viewers, and some methods are discussed in the my paper ‘Modelling inference in the comprehension of cinematic narratives.’ The abstract is below, and the pdf file can be downloaded beneath that. There are also some links to papers that provide the background theory to the concepts used in this article below.

Modelling inference in the comprehension of cinematic narratives

Abstract

The purpose of this paper is to outline some models of inference that can be used in describing and analysing the behaviour of real viewers in comprehending a cinematic narrative. The viewer’s processes of inference making in the cinema involve the framing of hypotheses about the world of the narrative which may be overturned by subsequent information and are, therefore, nonmonotonic. The viewer’s reasoning can be modelled mathematically, and two approaches are discussed here: the use of Bayes’ Theorem to represent and update the subjective and conditional probabilities of an agent is summarised, and Peter Abell’s Bayesian approach to the sociological understanding of narratives is outlined; and the transferable belief model developed by Phillipe Smets, in which the beliefs of an agent are represented by belief functions that do not assume an underlying probability distribution. In understanding narratives and the understanding of narratives it is useful to represent information visually, and an analytic and synthetic method of representing inference via Wigmore charts is outlined.

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.

    I could not agree more with your analysis regarding Humanities and empirical research. I work on a similar track, using eye tracking to determine the effects of certain cinematic devices and potentially uncover details of the perceptual and attentional processes. There is a gap, almost not understandable to me, in the epistemological base of most film theoretic frames.
    I currently work at Lansdown Centre of Middlesex University and I would be glad if we could further discuss the potential of empirical research in our domain.

  2. I’ve got a question if you don’t mind. Is there any methodological justification of the choice for the values of probabilities in the case of bayesian approach (for example, P(E2|H)=0.8 on page 12 and P(H)=0.3 on page 14) and for beliefs in the case of TBM approach (for example why low level of belief leads to m19(A8)=0.2 (page 19) and not to 0.1 or 0.001?)?

  3. The examples given are purely for purpose of illustrating the different methods. I don’t think that dealing with real viewers it would be necessary to use a value as small as 0.001 – I doubt that anyone would be that specific even in an experimental setup. What values real viewers would come up with is still unknown.
