Ecological Momentary Intervention for Post-Stroke Anomia

Anomia (i.e., impaired word retrieval) is one of the most common and debilitating deficits experienced by stroke survivors with aphasia, an acquired disorder characterized by impaired language. Although many anomia treatments exist, treatment response is modest and inconsistent across studies, and the extent of generalization to everyday contexts-the therapy gold standard-is largely unknown. The critical gap between actual outcomes and the therapeutic potential of naming therapy is tied to problems with current treatment delivery practices (i.e., low/unknown dosage, massed practice delivery, and decontextualized training). In this research, we aim to demonstrate that a novel smartwatch-based ecological momentary intervention (EMI) that delivers high-dosage semantic feature training throughout daily life has the potential for overcoming these issues. Every day for six weeks, 20 PWA will complete 24 trials of semantic feature EMI distributed over the day (from 10am-8pm) and delivered by a smartwatch. The EMI trial flow will include five steps: 1) a prompt alert and audiovisual "Ready to name a picture?" cue, 2) a first naming attempt after a YES response, 3) the repetition of an auditory model, 4) semantic feature verification via yes/no questions, and 5) a second naming attempt. To contextualize training further, trained items will be clustered into location categories (e.g., home, pharmacy), and we will use the mobile device's location detection to match PWA's location and it…
