Visibilities and the Analysis of Interdiscourse: The Case of Digital Health Practices

Abstract

This contribution examines the study of interdiscourses in visual discourse analysis. An expanded theory of interdiscursivity considers the integration, plausibility, and popularization of meanings, offering a perspective on ways of legitimating interventions and instructions or guidelines for action. Based on the reconstruction of meaning assignments, the expanded interdiscourse theory presented here opens up the possibility of tracing how power is exercised through the occupation of particular discourse positions, whether these are of a linguistic or of a pictorial/visual nature. With reference to poststructuralist theories, assignments of meaning are seen as inherently temporary and unstable. Whatever social reality is, it remains at least partially ambiguous and is determined anew in conflicts or tensions surrounding hegemonic negotiations. Visual discourse analysis thus focuses on the precarious nature of hegemony-building processes. How such adjustments of meaning through visualizations can be investigated within the framework of interdiscursive analysis is discussed using the example of the digitalization of body data via wearables.
