It sounds like you are hijacking the paper to talk about a pet theory. Did you find a cite on p11 about DNB? They refer to cognitive exercise, but not using that particular method. Whether that method is effective or not is orthogonal to their point.

Huh? They spend almost an entire page talking about DNB and WM training! (And BTW my points about DNB apply just as well to WM training in general.)

> Whether that method is effective or not is orthogonal to their point.

You are wrong. It is very germane whether it works.

Okay, I found the reference on page 10. Somehow my keyword search didn't work and we didn't number pages the same way.
