LIONESS Lab is an online tool to build interactive experiments

Easy and fast development

To speed up the developement process LIONESS Lab offers a simple what-you-see-is-what-you-get environment to click together your LIONESS experiments. Just combine different elements to design the participants’ interface and add some javascript for calculations.

Live web-based interaction

LIONESS experiments included standardized methods which deal with matching, forming groups, reducing attrition and other problems which arise with online experiments. In contrast to other products the focus is on online live interaction within groups. LIONESS experiments do not have to be played with a strategy method, but participants get live feedback from others.

No installation needed

LIONESS Lab is hosted as a web-based plattform. So you just have to create an account and can directly start with designing and testing your LIONESS experiments. You can also download LIONESS experiments and run them on your own server.

Share your experiments

LIONESS experiments can be shared with other experimenters or co-authors. A growing repository of LIONESS experiments provides a good starting point for developing own experiments by modifying existing ones. Experiments can set to be private but after publication be shared with others for replication.
