A parent doing their own "research" can quickly dispute these claims. A popular term in the parent community is "screen kid" to describe those kids who come for a play-date but literally don't know what to do when there isn't a screen in their hand. Screen kids tend be more neurotic, distractible, emotional and totally addicted to screen time. It's a little bit of a hot topic since the parents who rely more on screen-time to manage their children tend to disagree.
