DICE App

In just a few clicks, you can create and customize stimuli for your social media experiment. No coding required. The following form walks you through the process of creating your own DICE session.

The database will be reset on Friday, December 12, 2025 at 12:00 PM CET. This will permanently delete all data and no studies should be run at this time.

Before this date, please:

Study Slots

How many participants can start your study. Up to 400 participants are available by default. For larger sessions (up to 1000), authorization is required—you'll be prompted to enter credentials below. Note: If you're just testing, keep your sessions small to avoid unnecessary database strain. Remember: Some participants may not complete the study, so allocate extra slots to account for dropouts.

Study Instructions

You will be shown a social media feed. Please browse through the content naturally.

Take your time to read the posts that you find interesting.

Note: The whole briefing page is skipped if you leave this field empty.

5. Measurement

Plese use the following forms to define what you measure and how you measure it.

Insert Your Survey's URL

Configure this field (by providing a url directing to your survey), if you want to expose your participants to a survey after the feed. We'll create a redirect with url parameters to pass both the participant ID as well as a participant's treatment group/condition. Make sure that your survey tool accepts the url parameters (see embedded data documentation if you are using Qualtrics). If you leave this field empty, the study will close with an end of survey screen that provides your contact information provided above.

Dwell Time Tracking Threshold

This setting determines the visibility threshold for tracking dwell time. It represents the percentage of a social media post that must be visible to the participant before it's considered "in view". A lower value (closer to 1%) will track social media posts as soon as they're barely visible, whereas a higher value (closer to 100%) will only track rows when they're almost fully visible.
