Wave 1 of the Middle Childhood Cohort consisted of an online questionnaire and a lab visit in which participants were observed while performing several tasks. During some of the tasks, brain structure- and activity was measured by means of (f)MRI. Additionally, physiological samples were taken (e.g., DNA samples). Participants were also asked to take measurements on their own at home for several days after the lab visit.
