Frequently Asked Questions
Do you pay me for participating in experiments? How much?
Unless you are participating for extra-credit points in a class, yes, the experiments use cash rewards. As a participant, the average per hour participation payment is $25/hr. This means that a participant may receive a payment that is more than this or possibly less. The actual size of the payment depends upon your decisions, the decisions of others in the experiment, and random variables.
Do I have to show up when I am invited to an experiment?
When you receive an email inviting you to an experiment session you can either ignore the invitation or register in the session by clicking on the link provided in the invitation. After registering in a specific session you will receive an email confirming your registration.
After registering for a specific session you will be expected to keep your appointment by arriving at the lab at least 5 minutes before the start of the experiment session. If you fail to keep your appointment, the session might have to be cancelled, which will negatively affect the experimenters and the other registered participants.
I see that there are sessions with free places in the calendar, so why can't I sign up for these sessions?
For most experiments only a random subset of the potential participants are invited. Sometimes only participants with certain characteristics, for instance people who have not participated in some previous experiment, are invited. Thus, it is possible that you see experiment sessions in the calendar but are not invited for them.
Who can apply for a subject account?
Anyone who is interested in participating in experiments can apply for a subject account. However, to participate in laboratory experiments, you should be able to come to our laboratory.
Should I put in fake information when creating a subject account?
No, never do that. Your information is a crucial element of the experimental research. You will not be allowed to participate in an experiment if your profile or part thereof is found to be incorrect. In case you do not want to provide certain information about yourself, just leave the field blank. Note, however, that providing information will increase the probablility to be invited in experiments which target specific characteristics.
How can I cancel my registration for an experiment?
There is no online option that allows you to cancel your registration in an experiment session. Please double check that you are available for an experiment BEFORE you register; however, if you become ill or are not able to attend due to some unforeseeable event, please send an email to the experimenter who sent you the invitation to participate (or [email protected]) explaining why you cannot keep your appointment.
Registered participants who are no-shows or repeatedly cancel appointments will be removed from the list of potential participants.
I signed up for an experiment, but cannot sign up for all the other experiments now, since they just disappeared!
Nearly all experiments consist of several sessions using totally different participants. You can register in only one session for a given experiment. If you are registered, the other sessions in that specific experiment will disappear from the list.
What is the meaning of the three question marks "???" next to an experiment in the list "Experiments you participated in"?
After conducting an experiment we need some time to update the recruitment database. If the experimenter has not filled in the participation data yet, there will be the three question marks as your "show-up" status for the experiment. Once the data is entered, the status will change to either "yes" or "no".
