The researchers reexamined 56 peer-reviewed, published papers that conducted 90 fMRI experiments, some by leaders in the field, and also looked at the results of so-called “test/retest” fMRIs, where 65 subjects were asked to do the same tasks months apart.

The Adolescent Brain Cognitive Development study tested 4,500 9-10-year-olds in its first released dataset. The ABCD study is the largest long-term study of brain development in U.S.
Early data from the study, analyzed by another group of researchers from the CHEO Research Institute’s Healthy Active Living and Obesity also showed that kids who spend less than two hours a day on screens, participated in 60 minutes of moderate-to-vigorous-intensity physical activity, and received nine to 11 hours of uninterrupted sleep had higher cognitive abilities.Cognition was measured by language abilities, episodic memory, executive function, attention, working memory, and processing speed.
