Does this factor in the impact of constant instant-gratification of whatever is done on that screen?
Because (subjectively) I can see how children with lots of screen-time have a harder time with activities which do not lead to immediate dopamine release, like reading, listening to a story, drawing, etc., while children with low/no screen-time can derive satisfaction already from the process of doing something.

Edit: I'd say none of this impacts "brain function or well-being" directly, as both CAN do tasks without instant gratification, it's just that children with lots of screen-time perceive them vastly different from my personal observation.
