When something doesn't grab me, it takes enormous effort to maintain focus. It's not that other distractions are just so incredibly moving that they take my focus away. Rather, it's that it's physically difficult if not painful to focus on the thing that evades my attention, so by comparison, anything else is better.
I have no idea if my comment speaks to the paper. I started reading it because I am at the grocery store and the checkout line is so boring, but then the paper didn't quite grab me enough either, so I'm slightly more interested now in whatever happens to be on some other screen.
But if it is studying the effect of distractions, I think they have the wrong idea (or I have something other than ADHD), because it's never about the distractions, it's about the interest in the thing that needs my attention. Nothing else matters
