Registration as an Experimenter

All registered experiments at C.E.L.S.S. need to show approval by Columbia’s Institutional Review Board, as well as agree to comply with the lab’s rules. Below is a summary of the rules, which are further elaborated in the usage agreement.

  • Lab usage, including testing and experimentation, should be within lab opening hours.
  • Lab booking for experimentation can be done no more than 10 days in advance. Booking for the same project cannot exceed 8 hours a week. In case of cancelled experiments, participants need to be notified as early as possible.
  • All experiments must follow a strict no-deception policy.
  • Recruitment for all lab experiments is expected to take place through C.E.L.S.S.’s subject recruitment system.
  • Participants must be paid at least $5 for showing up at the scheduled session that they register for. For lab experiments, experimenters should choose parameters leading to an average payment of at least $15/hour, including the show-up fee.
  • Experimenters need to be present at the lab at least 30 minutes before the start time of their experiments.
  • After the experiments, experimenters must leave the lab at the state it was in upon arrival.
  • Experimenters are not allowed to install any software in C.E.L.S.S.’ computers.

To register as an experimenter, researchers need to sign the lab usage agreement and ORSEE usage agreement. They can then email the agreement forms to the lab manager at to request for an ORSEE account.

Before conducting an experiment, researchers will need to test their softwares at the lab and send the lab manager the experiment’s IRB protocol approval with the name of the approved experimenters listed. Graduate students will also need to be certified by the lab director, associate director or the lab manager that they are qualified to run their own experiments.
