Morning types wanted for the "Chronotype" study – male only!
Everyone has a natural inner clock that influences when they feel most energetic and alert – this is called chronotype. Some people are naturally early risers, performing their best in the morning. If this applies to you, we are looking for you to take part in our study!
The IfADo is investigating how chronotype influences brain activity and how it may be related to mental health. For this purpose, MRI scans and cognitive tasks are used.
A moderate morning type are considered for this study, therefore your chronotype must be tested first. Please complete the following questionnaire in advance (https://www.ifado.de/de/chronotyp) and send a screenshot of the results by email to Yiwu Xiong (xiong@ifado.de).
You can only participate if your chronotype test result shows that you are a moderate morning type. If this is not the case, unfortunately, we won’t be able to include you in the study.
The study takes approximately four hours and compensates 70€. Alternatively, students from TU Dortmund or Ruhr-Universität Bochum can receive credit hours (VPN).

The appointments will be arranged in consultation with Yiwu Xiong.
To perform the study, you will need to attend 3 sessions:
- Session 1 - outside the MRI (1 hour)
- Session 2 - inside the MRI (1.5 hours)
- Session 3 - inside the MRI (1.5 hours)
Sessions inside the MRI have a fixed schedule: one at 8 am and the other one at 7:30 pm.
