Visual Elicitation Critical Discourse Analysis

Any visual material that can meaningfully prompt participant talk is acceptable: maps, artworks, infographics, film stills, archival images, or drawings. The key criterion is that the material is theoretically relevant to the research question and capable of generating substantive discourse. Photographs are most common because they are familiar, accessible, and easily reproduced, but the choice of medium should be driven by what will best surface the discourses of interest.

Standard CDA analyses existing texts — media articles, political speeches, policy documents — for their discursive construction of power. VECDA adds a prior elicitation stage: visual materials are used to generate new discourse from participants, and both the images and the elicited talk become the analytical corpus. This makes VECDA more interactive and participatory, and it introduces an additional semiotic layer (the visual) that must be analysed alongside the linguistic.

There is no fixed rule, but 10–20 participants is a reasonable range for individual interviews; focus groups of 4–8 are also common. The deciding criterion is theoretical saturation — the point at which new elicitation sessions are not revealing new discursive patterns. Because VECDA is analytically dense, smaller purposive samples with deep analysis are preferred over larger superficial ones.

Fairclough's three-dimensional framework is the most widely used and provides clear analytical categories (text, discursive practice, sociocultural practice). Wodak's discourse-historical approach is preferable when the research has a strong historical or context-tracing dimension. Van Dijk's socio-cognitive approach suits studies focusing on mental models and ideological reproduction. Choose the framework that best matches your research question and substantiate the choice in your methodology section.

Obtain informed consent from any identifiable individuals depicted in researcher-selected photographs, or verify that images are in the public domain. For participant-produced photographs, participants must consent to sharing images that depict others. During analysis and publication, anonymise or blur identities unless participants have explicitly consented to identification. Document your ethical decisions in a reflexivity statement.
