> So is this paper saying that if my daughter had done activities instead of read (like play video games or run around outside) she'd be just as good a reader?
No, they are saying that your daughters overall cognitive skill would be equal. So maybe she’d be worse at reading but better some other cognitive skill (say, special recognition). Basically there’s no free lunch—if you spend on one thing you aren’t spending it on something else.
