Instructions for participants
Please take care to arrive in good time. You can find instructions on how to find us here at the CBRU webpages. If you are late, please inform the experimenter by phone. In some studies, you may be asked to fill in forms or questionnaires in advance. If so, please remember to bring these forms with you.
You do not need to prepare for the experiment in any particular way, unless the experimenter has given you special instructions. However, we hope you will not show up very tired, intoxicated or ill. If you are not feeling well or if you are tired, simply contact the experimenter to reschedule the appointment.
If you use contact lenses, we would prefer you to bring glasses instead and use them during the experiment.
Should your experiment take place outside the office hours (Mon-Fri 08-16), the door of the department may be locked. Under these circumstances, please make sure that you have the experimenter’s phone number.
If you would like more details about the study you are going to participate in, please contact us.
What happens during an EEG study?
We use all main neuroimaging tools in our studies, but the following text is about our electroencephalography (EEG) studies. Occasionally, we use behavioural and other measures, such as neurocognitive tests, instead of or in addition to EEG. When participating in these studies, you will receive separate instructions.
Prior to the start of the EEG experiment, we will place an electrode cap on your head. In order to measure the electrical activity of your brain, we connect the electrodes with a bit of water-soluble gel. The preparations take approximately 20 minutes. Experiments usually consist of different parts, and some may include an active task, while in others you just listen to sounds passively. In active tasks, you will be presented with different types of stimuli and you need to react to them in some manner, such as by pressing a button. During passive tasks you are usually simply instructed to watch a silent movie for the duration of the task.
In case your child is taking part in an EEG experiment, you can be with him/her at all times, also in the test room. Specific instructions will be given to you on the testing day.
As a research method, EEG is quick, non-invasive, and safe. The only inconvenience that you may experience is the small amount of water-soluble gel left in your hair. After the study, you can therefore use the shower and wash your hair. Shampoo and towels are provided.
If the experiment is long and you feel tired, please ask for a break. We will also offer you some coffee/tea and a small snack.
Privacy and the recorded data
When participating, you will be asked to read and sign a consent form, which allows the researcher to use the recorded data for a scientific purpose. In most of our studies, we do not inspect data recorded from individual subjects but rather look at averages of a larger group. If detailed analysis and publication of individual data is deemed necessary, all data are analysed and reported anonymously.
Reward for participating
We compensate for your participation in the experiment by offering, for example, movie tickets or cultural vouchers. It is possible get a small amount of money instead, but in that case taxes will be reduced.
Interested in participating?
We are constantly looking for people with different backgrounds to participate in our experiments. If you are interested in participating, please contact us. The best way to contact us is by sending an e-mail: firstname.lastname@example.org.
In your e-mail, please mention your name, age, and contact details. Occasionally, we are also looking for babies and children to participate in child-friendly studies. If you are interested in participating with your child, please mention the age of your child in your e-mail.
