Rules and Policies
In order to guarantee all research studies proceed smoothly, both experimenters and participants are expected to follow a set of rules and policies.

Please make sure to read them very carefully.

Invitation Policy

When we open a new experiment for registration, we send out e-mail invitations to some or all the people that have signed up for experiments. Once you have received an invitation, if you would like to participate to that experiment, please sign up for one session by following the instructions in your invitation email. Otherwise, just ignore the invitation. Ignoring one or more invitation will not affect in any way the chances of being invited to participate in another experiment.

We usually run several different sessions of the same experiment, so there are often multiple times and dates from which you can choose. Sign up for only a SINGLE session, as you can participate in an experiment only once. By signing up for a session, you commit to participate in that specific session.

You can unsubscribe from the invitation emails at any moment without penalty. If you want to erase your pertinent information from the database as well, you can send us an email. We will then proceed to replace your record with dummy entries (for example, your name will be replaced with "deleted_name").

No-show policy

If you decide to sign up for an experiment and you can no longer attend, please contact us as soon as possible at bussel@brown.edu. We track the number of "no-shows" for each participant and reserve the right to exclude from ORSEE participates who regularly do not show up to an experiment after they have registered for them. Letting us know you can no longer participate in advance will ensure there are no "no-shows" on your account.

Punctuality

If you sign up for an experiment, please arrive at the lab or log on 5-10 minutes before the starting time of the session. Please be aware that experimenters usually recruit more subjects than necessary, in order to make up for last-minute cancellations from participants. After the scheduled start time, anyone who registered for an experiment (that is, was invited and confirmed his participation in a specific session) but did not show up will not receive any compensation for that experiment.

Strict no deception policy

BUSSEL implements strict no‐deception policy, meaning that all information you are told during experiments is truthful. This may not be the case for experiments in other laboratories or fields of science.

Voluntary participation

Participation to BUSSEL studies is completely voluntary: by signing up for our subject pool, you just agree to receive email invitations to our studies. Moreover, you may change your mind about participating at any point during the experiment. If you do so, however, you will not be entitled to any compensation for that experiment. Please keep in mind that, depending on the type of experiment, this may entail that the experiment has to conclude for some or all other participants.

Compensation Policy

If you show-up to the laboratory or log on in time (depending on whether the experiment is in-person or online), you will receive a minimum show-up payment. This will be the case even if there are more subjects than needed and you will not be allowed to participate to that particular session. In addition, you can earn more money depending on your decisions, the decisions of others, luck, and on the length of the experiment. Average total payments typically range from $10-$25, but there can be more variation in the earnings of given individuals. The normal method of payment is either cash or gift cards. You will be paid privately at the end of the experiment: no one else will know how much you earned. Payment method and show-up fee will be clearly indicated in the invitation emails you will receive.

Internal Review Board approval

All experiments that you will be participating in (with the exception of those run by students for class projects) have been approved by the Institutional Review Board of Brown University (IRB). The IRB is in charge of making sure that the experiments comply with all federal regulations, and in particular that each participant has expressed his or her informed consent, and that the experiment does no harm. If you have any questions regarding your rights as a research participant, you may contact the Brown University Human Research Protection Program at (401) 863-3050.
What you consent to

By clicking "Yes" below, I understand that:

  • By signing up to the subject pool, I just give permission to BUSSEL to send me invitation emails to research studies, and I am free to decline participation in any particular research study at any time without penalty.
  • I am giving my permission to BUSSEL to retain my name and pertinent information for future research.
  • I can remove my name and pertinent information at any time as indicated in the rules and policies described above.
Do you agree with the rules, policies and the consent statements above?
