The effects of virtual reality immersion on the content and structure of the narrative discourse of healthy adults.

What is already known on this subject As an ecologically valid tool, discourse analysis is often used to assess daily communicative exchanges in adults with acquired communication disability. Clinicians and researchers using narrative discourse assessment must balance the experimental control and diagnostic reference sample capabilities of structured tasks with the ecological validity and real-life transferability of unstructured personal narratives. What this study adds to existing knowledge This study explores the use of immersive VR technologies to create standardized, replicable, immersive experiences as a foundation for narrative discourse assessment. It highlights how the 'sense of presence' in a virtual world can prompt healthy adult speakers to retell a narrative of a personal experience that can be replicated for many different participants. The results suggest that immersive VR narrative assessment for adults with communication disability may balance ecological validity with measurement reliability in discourse assessment. What are the potential or actual clinical observations of this work? Immersion in VR resulted in the production of narratives with morpho-syntactic features that aligned with typical narrative generation, rather than retell. Participants used more first-person pronouns, suggesting retelling of personal experience. Though further study is needed, these preliminary findings suggest clinicians can use immersive VR stimuli to generate structured story generations that balance experimental and diagnostic control with ecological validity in narrative discourse assessment for adults with communication disability.
