One of my mom's credentials is a degree in early childhood development.

She and her peers from that life were pretty set (since the mid-70's) that putting children younger than 12 or so in front of 'screen media' had negative affects on social and cognitive development.

The rationale, as far as I understood it, is that young kids are voracious learners and screen media at it's best is a shallow and hyper focused projection of the day-to-day reality experienced by humans.

Thus, any time spent on screen media equates to lost training time/data which is always a negative if you are trying to build a general purpose human being.

Books which required effort to comprehend were fine, but interaction with peers, older humans and the outside world was preferable to all else.

EEG readings to prove things about executive function may suck, but the conclusion still seems somewhat intuitive.
