In order to receive e-mail invitations to participate in experiments and other studies at CBS, you must register in our database using this online system. Please acknowledge the following basic rules of conduct:
- Register only once in the CBS participant database. Registering multiple accounts undermines our scientific research. Any participant found with more than one profile will be excluded from all future studies.
- If you receive an invitation e-mail, you must respond affirmatively if you wish to to participate. Spaces in each study are limited, so please respond early if you would like to participate.
- When you register for a study, please check carefully that you will be able to participate. Registration may be cancelled until 24 hours before the session, but please avoid cancelling if at all possible. If you sign up for an experiment but do not show up on time, we will register this as a "no show". After two "no shows", you may be excluded from participating in future studies.
- Participants in studies may be compensated for their time in various ways, differing from lab to lab and from study to study. Any compensation for a given study will be indicated in the invitation e-mail for that study. In some studies, compensation may also depend on the decisions participants make during the study.
- During a study, participants must follow the directives of the researchers. The researchers will identify themselves before the start of the session.
- In some cases, the exact number of participants is crucial in order to complete a study and it may therefore be necessary to recruit extra participants. This occasionally means that not all registered participants will get to participate, but all participants who have signed up and show up will be compensated according to the information provided in the invitation letter.
- Registration in the database and participation in studies are always voluntary. The information that participants provide when registering in the database may be used to target certain studies to certain groups, e.g. specific age ranges.
