Es scheint sich um eine auf 10 Jahre angelegte große Studie des NIH namens ABCD zu handeln, die momentan noch nicht einmal Halbzeit (*) erreicht hat. Schlussfolgerungen auf Grund vorläufiger Ergebnisse sind daher mit absoluter Vorsicht zu genießen. Ansprechpartner für diese Studie ist Dr. Gaya Dowling.
Adolescent Brain Cognitive Development (ABCD) Study
ABCD is a landmark study on brain development and child health supported by the National Institutes of Health (NIH). This project will increase our understanding of environmental, social, genetic, and other biological factors that affect brain and cognitive development and that can enhance or disrupt a young person’s life trajectory.
Letztes Jahr hat das CBS Nachrichtenmagazin "60 Minutes" über diese Studie berichtet (Hervorhebungen von mir):
Anderson Cooper: What is a thinning of the cortex mean?
Dr. Gaya Dowling: That's typically thought to be a maturational process. So what we would expect to see later is happening a little bit earlier.
Anderson Cooper: Should parents be concerned by that?
Dr. Gaya Dowling: We don't know if it's being caused by the screen time. We don't know yet if it's a bad thing. It won't be until we follow them over time that we will see if there are outcomes that are associated with the differences that we're seeing in this single snapshot. [...]

NIH to Launch Adolescent Brain Cognitive Development Study
This summer the National Institutes of Health (NIH) is launching a major longitudinal study on child health and brain development that will be of interest to many in the education research field. The Adolescent Brain Cognitive Development (ABCD) Study, which examines how childhood experiences affect brain and cognitive development of adolescents, will be implemented through schools and will include teacher assessments of children in addition to child and parental interviews.
“Our study will be looking at many childhood experiences that affect brain, social, emotional, and cognitive development, including those that directly affect classroom behavior and academic success,” said Gayathri J. Dowling, director of the ABCD project at NIH.
