LIONESS Lab is developed by the Centre for Decision Research and Experimental Economics (CeDEx), University of Nottingham and the Chair of Economic Theory, University of Passau
Easy and fast development
Live web-based interaction
LIONESS experiments include standardized measures to deal with methodological challenges of online experiments, such as forming groups, retaining participants’ attention and handling drop-outs. LIONESS focuses on online interactions, in which participants get live feedback from others.
No installation needed
LIONESS Lab is a fully web-based platform. This means that you only have to create an account and can directly start to develop and test 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 and co-authors. The growing repository of LIONESS experiments provides a good starting point for developing your own experiments by modifying existing ones. You can choose to make your experiments ‘private’ or publicly share them with others, enabling others to build on your design and facilitating replication of results.
LIONESS Lab currently runs as a beta version but is already used by many experimenters in different institutes around the world.
With LIONESS Lab you can run your experiment and collect data directly from your office. To recruit participants, you can publish a link to your experiment on online crowd-sourcing platforms like Amazon Mechanical Turk or Prolific.ac.
