Apparently scientists are reporting that this new exercise is the first known to significantly raise IQ, not just test taking ability.

It is called Dual-N-Back Training, and you can try it yourself at ... doh! never mind..

Which you will have to google and find yourself for whoever is running this site in their infinite wisdom decided to not allow URL postings until a certain number of posts..

Thanks for the post.

Is it the site at http://www.soakyourhead.com ?

The site cites a PNAS paper called "Improving fluid intelligence with training on working memory" with the following abstract, in support of using the Dual N-Back training to increase fluid intelligence:

Abstract

Fluid intelligence (Gf) refers to the ability to reason and to solve new problems independently of previously acquired knowledge. Gf is critical for a wide variety of cognitive tasks, and it is considered one of the most important factors in learning. Moreover, Gf is closely related to professional and educational success, especially in complex and demanding environments. Although performance on tests of Gf can be improved through direct practice on the tests themselves, there is no evidence that training on any other regimen yields increased Gf in adults. Furthermore, there is a long history of research into cognitive training showing that, although performance on trained tasks can increase dramatically, transfer of this learning to other tasks remains poor. Here, we present evidence for transfer from training on a demanding working memory task to measures of Gf. This transfer results even though the trained task is entirely different from the intelligence test itself. Furthermore, we demonstrate that the extent of gain in intelligence critically depends on the amount of training: the more training, the more improvement in Gf. That is, the training effect is dosage-dependent. Thus, in contrast to many previous studies, we conclude that it is possible to improve Gf without practicing the testing tasks themselves, opening a wide range of applications.




Btw, the block on posting urls until a certain number of posts is made (I think it's 5) is to discourage spammers, and has worked quite well.

wooh 96.7% on dual 2N back first try. That is really supposed to help with IQ? It didn't seem very difficult.

I haven't found anything online for going beyond 2; i.e., dual 3-back task

LMs sight has 4 back testing, but it is even easier than the 2 back.

http://www.lumosity.com/

of course nothing is free in this world except air

the Dual N-Back task at http://www.soakyourhead.com is free. However, for me, it always does the Dual 2-Back task, and I can't get the game to go to 3-Back or 4-Back.

i was referring to the luminosity programs

I don't quite get how to play this game.
So do you just press the key if something is repeated?
For example, for the auditory one, I press L whenever I hear a letter that has been presented before?

Cognitivefun. net has dual N Back up to level 9-N back and has an array of other cognitive stimulating games
