Feasibility of Immersive Virtual Reality for Delivering Semantic Feature Analysis to Adults with Communication Disorders and Normal Cognitive Aging

This study investigated the feasibility of delivering Semantic Feature Analysis (SFA) within a fully immersive virtual reality (VR) environment for adults with normal cognitive aging (NCA) and communication disorders (CSD). The scope included short-term semantic feature training, baseline assessments, and evaluation of engagement and acceptability. Thirty-five adults (11-younger, 11-older, and 13-CSD) completed a two-phase protocol involving standardized SFA and VR-delivered SFA (VRSFA) across five tasks: picture naming, associative matching, common feature identification, semantic feature questions, and integrated SFA training. Participants completed cognitive and language assessments pre- and post-intervention, with qualitative feedback gathered through thematic analysis. Quantitative data were analyzed using non-parametric tests to assess group differences and task effects. Findings indicate that immersive VR is a feasible, engaging, and promising approach for delivering evidence-based semantic-feature training for individuals with typical and impaired cognitive communication profiles. Results support continued exploration of VR as a scalable and accessible rehabilitation modality in speech-language pathology.
