Study Participation

Start study without data recordings

Data Recordings

Activate data recording to allow participants to take part in your study and for data to be collected.

Click to run the study with data recordings

Dataset Unlocking

This setting controls how data sets will be unlocked and hence how you use your data recording quota.

Online Participation / Study Published

Publishing your study allows external participants to access it via a public link.

Online Participation Link

This is the main link to your study that you can share with participants once your study is published.

To create custom participation links, please refer to the sections below on URL Parameters and utilize the Build Custom Link area of this tab.

Player Forward Shortcuts Active

Enable this option to allow participants to use keyboard shortcuts to navigate through the study. CNTL+Q to jump to the next task, CNTL+X to jump to the next frame. While this option is handy when testing your study while building it (before official data collection begins), it is advisable to disable it once the official data collection process begins.
