Question

Researchers asked parents of 19 American children, ages 8 to 12, to complete surveys on the number of
hours their children spent reading and the number of hours they spent on screen-based media time.
Each of the children also underwent magnetic resonance imaging (MRI) to assess connectivity in the
brain. More time spent reading was associated with higher connectivity, while more screen time was
associated with lower connectivity in the brains of the children.
