IQ boost with dual n-back task
IQ or Intelligence Quotient is a measure of intelligence according to some standardized tests. It is generally inherited, but childhood environment (nutrition etc.) plays a part too. Until now, no exercise was known to improve adult persons IQ.
In New Scientist article: "Simple brain exercise can boost IQ":
You can play the game yourself. Try first single 1-back, spatial or auditory. The main task, which is claimed to raise IQ, is dual 2-back. For most people it is quite a difficult, so try easy ones first. Do simple task until you get continuously over 90% scores and then move on to harder ones.

I noticed there is a commercial dual-n-back software, which is much more convenient to use than this free web applet. You can download it on your computer or use it with iPhone. It got "Top Ten Tech Gifts Under $50" from PC Mag online, so check it out:
