6 - Study design



The abilities to talk, to carry on a conversation, and to tell stories are central to us; they are constitutive acts through which we create, embody and perform our selves. Conversation is ontogenetically prior to narrative, developing in tandem with language: two and three year olds can carry on simple conversations: story telling develops around four years of age, co-incident with the emergence of episodic memory and theory of mind. Because of their centrality in our social and cognitive lives, narrative and conversation tasks are increasingly used in study designs to investigate linguistic, discoursal and cognitive patterns. Narrative and conversation tasks provide naturalistic, ecologically valid data which can be used to identify both positive and negative features in discourse.

In this chapter, we explore narrative and conversation tasks for three commonly investigated areas: linguistic structure, narrative and memory. We outline issues in study design based on the models presented in previous chapters. Linguistic structure is commonly investigated in contexts of language development and in speech disorders and is central in the evaluation of speech performance in educational and clinical settings. We discuss morphology and syntax as two areas of linguistic structure in interaction with information processing load as represented in the conversation of speakers with AD and an ASD in Section 6.2. Narrative occurs universally and is important in our cognitive representation of events (van Dijk and Kintsch 1983; van Dijk 2006).
