Research-use note
This browser task is a research proxy rather than a diagnostic instrument. Display refresh, browser scheduling, device latency, screen size, and input hardware can affect measured reaction time, so cross-device absolute comparisons require caution.
This resource is not a clinical diagnosis, treatment, professional assessment, or crisis service. Researchers remain responsible for ethics approval, lawful processing, suitability, deployment, and interpretation.
