Here you can read about how you participate in experiments
You are paid for your participation
All participants recruited through our recruitment system (Sona) are compensated for their time spent on participating in studies and experiments. We recommend to our researchers that they pay around 110 DKK per hour. You can either be paid by bank transfer, gift voucher, lottery or another form of payment. Note that in some studies the amount you receive can depend on how you solve your task in the experiment.
Read more about payment
If participants are recruited outside our recruitment system, it is up to the researcher(s) to decide how participants are compensated.
It's exciting and you never know what happens
The experiments vary greatly, and each offers a unique experience. The studies are on human behaviour and cognition, and as a participant you often perform tasks in front of a computer such as problem solving, questionnaires, decision making and so forth. Some studies use various forms of technology such as eye tracking or virtual reality. You can find a general description of each study at our participation website and choose the ones that interest you.

You help researchers at Aarhus University
All researchers at Aarhus University have access to conduct studies at COBE Lab. Each study needs a sufficient number of participants to get results that are as valid as possible. That is why your participation makes a difference for the researchers.

All persons over 18 years of age
All members of the public aged 18 or above have the opportunity to participate in studies. You do not need to be a student.
You need a danish CPR-number
Most studies require you to have a Danish CPR-number. The payment to your bank account or a gift voucher requires a CPR-number as audit documentation.
EasyAccount (NemKonto) recommended
Most studies are paid via bank transfer by Aarhus University's salary system, for which you need a CPR-number and an EasyAccount (NemKonto).
All you have to do is create an account in our online participation system. Subsequently, you can browse and sign up for studies that interest you. Here is a step-by-step guide of what to do:
When you arrive for the experiment you will be asked for your SONA ID. Researchers at COBE Lab do not know you by name or your email address, but only by your SONA ID (ID Code). It is therefore important that you remember your SONA ID or have it written down somewhere, where you can quickly find it.
Your ID Code is generated by the Cognition and Behavior Lab Participation System automatically, and not by you. You can not change your ID Code.
Find your SONA ID
When you sign up for a study you will receive an email confirmation. Your SONA ID can also be found in this email confirmation.
Or you can find it in your account information:
1. Log in to the participant system with your User ID (not your SONA ID) and password
2. Click My Profile in the upper right corner
3. You will see a four or five digit number corresponding to Identity Code. Underneath this number it is stated "Researchers will see only this code, and never your name". This is your SONA ID.
ALWAYS remember to cancel, if you are not able to show up for an experiment you signed up for. You can easily cancel your sign-up at the participation website or in the app. If it is too late to cancel, you can send an email to the researchers of the study. Their contact information is found under the description of the study, where you signed up. In emergency cases you can also write to firstname.lastname@example.org
Too many unexcused no-shows deactivates your account
If you do not cancel and do not show up for a session you will be marked as an unexcused no-show. If you get more than 1 unexcused no-show your account will be deactivated. Researchers spend a lot of resources and time planning the sessions and your absence can lead to a cancellation of the session. In case of illness please inform the researchers. If you cancel you will be marked as an excused no-show and have the possibility to participate in the study another time.
