2.2 Procedures
All participants were recruited through online and offline
advertisements (e.g., social media and poster advertisements) in the
area of Amsterdam, the Netherlands. Next, participants were asked to
provide online informed consent for an online screening procedure in
order to assess in- and exclusion criteria. On the research testing day,
participants provided written informed consent, completed all the
questionnaires, and received an MRI scan. All participants received
instructions to abstain from any drug use 24 hours prior to the MRI
scan.
