Archive of Completed Experiments

This page contains links to experiments that have been completed. You can click links to visit the experiments and see what it was like for the participants. Please note that prizes for completed studies have already been awarded, so do not expect to complete these for a chance at a prize. Some studies linked below as "in progress" or "in preperation" represent studies where the data have been collected, but the data analysis and writing have not yet been completed, or where follow-up studies are still needed to answer the question (so don't expect to do studies listed here for cash prizes, either).
