T3

Wave 3 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., hair and DNA samples). Participants were also asked to take measurements on their own at home for several days after the lab visit. Furthermore, to experimentally examine social enrichment, we included a parenting intervention, which allows us to investigate causal effects of parenting on social development. Between the 2nd and 3rd measurement, 40% of the sample received a video feedback intervention to promote positive parenting and sensitive discipline (VIPP-SD).
