Welcome to the Experiment Server
Columbia Experimental Laboratory for Social Sciences (CELSS)
Online Recruitment System for Economic Experiments (ORSEE)
If you want to register to participate in social science experiments at CELSS and thus change the world while earning money, it is simple, and there is only one way to do it.
Click the Register button on the left panel, or simply click here. A new page with our privacy policies and rules will appear.
Once you accept those rules, you will be able to fill a quick form in order to register in our system. And then you're done!
We will contact you as soon as an experiment where you can participate comes up. You will be paid each time for showing-up ($5) in addition to your earnings from the experiment.
Registration is open to only Columbia and Barnard students.
If you are a researcher and you would like to conduct experiments using our recruitment system, please contact the lab manager at email@example.com for more information.
If you have any question, please consult the FAQ and tell us if we answered your question well. You can also find more information on our blog. If you see ways to improve the recruitment system, or if you do not find your question in the FAQ, please e-mail us using the link at the bottom of the page.
Thank you for showing your interest and we hope to see you soon in the laboratory!
