As long as it's correlations and there's no biochemical pathway it's little more than social sciences. I have to wonder if they don't have the correlation reversed, ie, parents who park their kids in front of screens at a younger age (because of disinterest) read less to them and provide a less stimulating and engaging environment for their children.
