Update (04/20/10): after read­ing the full BBC study in Nature, I wrote the arti­cle titled BBC “Brain Train­ing” Exper­i­ment: the Good, the Bad, the Ugly, say­ing that “you prob­a­bly saw the hun­dreds of media arti­cles titled “brain train­ing doesn’t work”, based on a BBC exper­i­ment. Once more, claims seem to go beyond the sci­ence back­ing them up … except that in this case it is the researchers, not the devel­op­ers, who are respon­si­ble.” You can keep read­ing full updated arti­cle Here.

Below is what I orig­i­nally wrote before the paper itself was available.

Tomor­row we’ll prob­a­bly wit­ness a lot of media cov­er­age about a exper­i­ment run by the BBC in the UK, to be pub­lished in Nature, on whether “brain train­ing” works.

The paper is still embar­goed, so we can­not com­ment on it, but what I can do is to share frag­ments of my email to a BBC reporter six months ago, dis­cussing impres­sions on what they had announced as the ulti­mate test of whether “brain train­ing” works.

Again, these were purely my impres­sions based on lim­ited pub­lic infor­ma­tion. Once we can com­ment on the pub­lished paper we’ll be able to pro­vide a more informed perspective.

“Hello XYZ,

Here go some of my thoughts based on my exter­nal per­cep­tion of your test:

• I agree with many of the premises for the test
• But “Does brain train­ing really work” is a highly mis­lead­ing frame: the obvi­ous answer is, yes, it works as a cat­e­gory. If not, do you mean peo­ple can’t learn? med­i­tate? go through cog­ni­tive ther­apy? cog­ni­tive retrain­ing? increase work­ing mem­ory and other brain func­tions? All these are estab­lished beyond doubt through dozens of well-controlled stud­ies where the inter­ven­tion effect a) goes beyond placebo, and b) remains there once train­ing is over. The 2009 report I sent you includes 10 Research Exec­u­tive Briefs by lead­ing sci­en­tists who ref­er­ence pub­lished papers in high-quality jour­nals. None eval­u­ates Nin­tendo — but should they be ignored, as a group?
• Now, the key ques­tions are, “what spe­cific brain train­ing are we talk­ing about”, “work for what?” and “work for whom?”. That’s where we could help edu­cate con­sumers sep­a­rate hope from hype.
• …Right now you are invent­ing your own “brain game”, and the only thing you will test is whether that spe­cific “brain game” you have develop “works” or not (not clear what out­come mea­sures you have). I wouldn’t dare to man­u­fac­ture my own car now from scratch and claim, based on the results, that “cars” work or don’t.
• I couldn’t agree more with “brain train­ing that is good for one per­son might not be good for you”, since one of “brain train­ing” prop­er­ties (both strength and weak­ness) is its highly tar­geted nature. The impli­ca­tion? we need bet­ter assess­ments to pin­point bot­tle­necks and direct appro­pri­ate inter­ven­tion. con­sumers need bet­ter edu­ca­tion and infor­ma­tion to know what is a waste of time and money and what may be wor­thy. Yet, your test seems to fully ignore this, and test whether the same thing is good for everyone…you may be throw­ing out the baby with the water…”
