That seems a little pessimistic. Neither of the 2 DNB studies showing
physical brain changes (the fMRI and neurotransmitter studies) made
students play DNB for years. And IIRC, I believe I've seen meditation
studies which trained over only a few weeks or months and saw real
changes. Those experienced monks certainly may have more changes, but
that's not the same thing as it taking years/decades to make any
change. (There's likely diminishing gains going on there; one year of
meditation will make a bigger difference to someone just starting than
to someone whose practice is a score of years old.)

ok then, i need to repeat myself. please clarify what you say here:
"In the beginning of my training, I was extremely adamant about
increasing my n-back score. So for the first 3 days, I trained about
3-4 hours. After that, I became less enthusiastic about it so I
trained about 15-20 sessions 5 times a week."
nothing personal, just like the truth.
Interesting that you focus on the speeding aspect, and that jttoto
reports a 7 minute decrease in his test-taking time.
Didn't Moody's critique of Jaeggi focus on how the administered
Raven's was artificially sped up? (This suggests that 'all' DNB does
is speed up your thinking rather than put it on a whole new level. As
a sci-fi fan, I can't help but think of the distinction between 'weak'
superintelligence and 'strong' superintelligence!)
(On a side note, I've uploaded a fresh copy of the FAQ, with the last
couple weeks/months of changes. It's been a while since I refreshed
the static HTML.)
All very true; what we want is a culture-neutral IQ test. Raven-style
tests seems to be the closest we can get to pure Gf tests; I include
links to just Raven-style IQ tests in the FAQ (or at least IIRC I
included disclaimers about the ones that struck me as having
I believe jttoto's and most of the other reports use only these
