About the database of participants

  • The data stored in the recruitment system are used for scientific studies only. These data will not be passed on to third parties. The data will be used for the following purposes:
    • to inform participants about the latest studies;
    • to check the presence/absence of enrolled participants;
    • We do keep a record of which experiments you participate in, and which sessions you sign up for but do not show up. We do not retain any linkage between your records in the registration database and any decisions you make during the experiment sessions. That is, the only information that is kept from an experiment session itself is the information you give during that session.
    • Because this database contains private information (name, email, etc.) we must comply with some EU regulations. More specific, we must inform you that the UvA employs a Data Protection Officer (DPO) who can be contacted at in case of any questions.
  • Participants are able to determine whether or not they receive invitations to the latest studies. At the bottom of each email invitation you find a direct link to cancel any future invitations.

About participating in sessions

  • NO DECEPTION: we guarantee that the experimenter will never deceive you. For example, if we tell you that you are in a group and that your earnings also depend on the decisions of others, you can be sure that that this in indeed the case.
  • Signing up for a session represents a commitment on your part that you intend to be there. If circumstances change and you are not able to attend a session you signed up for, please cancel your enrolment as soon as possible so that we can offer your place to another participant. Failure to show up for a session may result in its cancellation, inconveniencing your fellow participants; please be considerate!
  • Sessions begin promptly at the announced time. Once a session has begun, it is not possible to join it in progress, and we will be unable to offer you a turn-away fee.
  • Of course, our data collection and use of the data is always according to EU and Dutch laws and regulations.
  • You are a voluntary participant and you can leave any time. However, the payment is only at the end of the experiment and if you leave early you will not be paid for your participation.
