Participant studies
Run a text, image, or video stimulus experiment
Show participants standardized communication material before assigning solo-AI, council, human–AI, or human interaction conditions.
The basic idea
Traditional communication experiments begin with a controlled stimulus and measure responses after exposure. The stimulus, media description, interaction task, condition assignment, transcript, exposure timing, and questionnaire should be preserved together so treatment delivery remains auditable.
Show everyone the same campaign message with a photograph or YouTube advertisement, then randomly assign them to discuss it with one model, an AI council, a human–AI chain, or a human-only condition before measuring attitude change.
How to do it
- 1
Enable the shared stimulus and add the heading, text, optional HTTPS image, or YouTube link.
- 2
Provide accessible image text and a neutral media description or verified transcript; model conditions receive this text context because they do not watch the embedded player.
- 3
Add the standardized interaction task and configure the four desired condition templates in the Guided Condition Builder.
- 4
Preview the participant path, lock the protocol, run a small test, and verify stimulus-opened, stimulus-completed, exposure time, assignment, transcript, and questionnaire fields in the export.
What to watch for
- A media description can introduce framing that is absent from the original stimulus.
- Remote images disclose a participant's network request to the image host; use a controlled HTTPS host and avoid tracking URLs.
- YouTube playback, advertisements, captions, region restrictions, and recommendation overlays can vary across participants.
What a useful result looks like
Each participant receives the same versioned material, an auditable randomly assigned interaction, and the planned outcomes, with exposure timing available for delivery and attrition checks.
