Cognitive accessibility engagement guide
This is a guide to facilitating online user interviews with participants who experience cognitive barriers. Remember that people experience barriers on a spectrum and that this guide is not exhaustive. Many of the following suggestions and considerations for researchers working with participants with cognitive barriers can be applied to any research session.
How to get started:
- Run 2-3 informational user interviews to get familiar with cognitive needs and challenges
- Add cognitive Accessibility Usability Scale (AUS) scores to your existing product benchmarks by repeating the same test protocol with 2-3 cognitive participants
- Run a usability study to explore navigation, content, icons and images, and layout with 2-3 cognitive participants

Best practices
What to avoid
Before your session
- Include warning of sensitive subjects in your research request description.
- Plan for a maximum of 2 topics or tasks per session.
- Prepare to screen share and show participants, not just tell or instruct them.
- Consider if you want a second researcher to focus on how the participant is feeling and responding. This could distract the participant or make them nervous to share freely.
In your discussion guide
- Give clear and specific instructions. Avoid vague and hypothetical scenarios.
- Provide an estimate for time-bound tasks, but don’t rely on participants remembering the time frame.
- Give reminders and prompts when it’s time to wrap up.
- Let them know when they’ve given enough feedback.
- Consider whether you’ll let participants go off-topic or bring them back on task.
During your session
- Ensure participants understand their rights regarding what they choose to share.
- If a participant is struggling, remind them that they don’t have to answer every question. They can stop and withdraw consent at any time.
- Introduce yourself and get to know one another, including checking on their accommodation requirements.
- Explain the purpose of the session, review provided materials and confirm their understanding.
- Use well-timed probing questions vs. expecting them to narrate aloud.
- Include reminders throughout and save questions until after a task is completed.
- Be aware of the higher risk of these participants experiencing stress, anxiety, disorientation and unpleasant emotions. Consider offering a break or gently guide them to a simpler task or question if this happens. Encourage them to reach out to Fable’s Community Team (community@makeitfable.com) for support.
