Media Stimuli in Research Surveys

Add images, videos, screenshots, prototypes, or other stimuli with clear routing and export documentation.

Use Media As Research Material

Media stimuli include images, videos, screenshots, ads, maps, policy pages, prototypes, and other materials that respondents inspect before answering. Build media blocks so the stimulus, follow-up measures, Flow, and exports are easy to audit.

Before launch, decide exactly what each respondent should see, how long they need to inspect it, which follow-up questions measure the response, and how the export will identify the displayed stimulus or condition arm.

Add Media To A Survey

  1. Step 1: Choose the display surface. Use Content Blocks for media that respondents only view, and Heatmap when click coordinates are the response.

    Add instructional text or embed a YouTube video as a stimulus.

  2. Step 2: Place the media in its own block. Use blocks so Flow can route different respondents to different stimuli and so the treatment page is easy to find later.

  3. Step 3: Add instructions before the media. Tell respondents what to watch, read, or inspect, whether sound matters, and whether they can continue immediately.

  4. Step 4: Add follow-up checks. Use comprehension or manipulation checks when the protocol needs evidence that respondents understood the stimulus.

  5. Step 5: Route experimental media in Flow. Use experimental conditions when different arms see different images, videos, or messages.

Export And Documentation

Record which stimulus each respondent saw, any condition arm, and any randomized order fields needed for analysis. Review Export Research Survey Responses before launch so media assignment data is present.

If the media is part of an experiment, store a stable stimulus label in your codebook, such as stimulus_policy_high_cost or ad_control_static. Avoid relying only on file names, especially when images are replaced during pilot revisions.

Prelaunch Media Checks

  • File stability: confirm the media is not hosted somewhere that may expire, require a login, or block respondent access.
  • Screen size: preview on a phone, tablet, and desktop if participants will use mixed devices.
  • Readability: check small text in screenshots, charts, and ads, especially if the task asks respondents to interpret details.
  • Accessibility: include text alternatives or surrounding explanation when the research design allows it, and avoid using color alone to communicate critical instructions.
  • Timing and attention: pilot whether respondents have enough time to inspect the media before the outcome questions appear.
