What you can actually do to make yourself become more intelligent? Is there anything that can make you more intelligent or improve your brain's abilities?

For many years, neuroscientists thought there is any way to increase one's I.Q. as an adult. According to this scientific view, you can do puzzles, performance tasks, resolve problems and learn new things, but doing that you're simply to exercise your brain and not really become more intelligent - because this didn't happen.

But... Recent research shows that this may be wrong.

According to a study published by the University of Michigan (USA), presented at the Association for Psychological Science (Washington), shows that playing “dual n-back” 20 minutes a day of 20 days, may actually improve the working memory (short term memory) and fluid intelligence. The memory task game helps to achieve better results in IQ tests since it increases the ability to reason and develop new problems.

“Fluid Intelligence refers to the ability to reason and to solve new problems independently of previously acquire knowledge” (Jaeggi, M. S., et al., 2008)


The game "n-back", created by W. K. Kirchner, in 1958, is a memory task that encourages the use of "working memory", which has the ability to retain information in short-term memory in an active way, even before interruptions, distractions or interference.

IQ Boost, which is presented here, offers three variants of the "n-back", namely the "dual n-back", which allows display the auditory stimulus at the same rate as spatial stimulus, increasing the difficulty of the game. The difficulty may also be increased by increasing the game’s time and the number of n-previous.

The game, like was presented by the authors’ paper, is quite simple, basically consists of a memory test on a continuous performance task, in which the player saw two series (or only one) of stimuli that were synchronously presented at the rate of 3000ms per stimulus. One string of stimulus consisted of a auditory stimulus (category of animals) whereas the other string of stimulus consisted of individual spatial locations marked on the screen. The task is to decide for each string whether the current stimulus matched the one that was presented n-previous in the series.

This mental exercise is great for children or adults who, when interrupted or distracted by something, have difficulty remembering what he they was doing. The game is especially recommended for students or for people who have a profession that requires great concentration, attention and the use of short-term memory, such as accountants, auditors, computer programmers or traders of the stock market.

Have fun while increasing your mental power ...

NOTE: Some players who don't know how to play this game and not try to learn how, has given a negative rating. Unfortunately, this notation is due to unwillingness to figure out how to play the game.

1- You only need to hit one or two buttons (eye or/and audio image button).
2- If you hit the center of the screen you return to home screen.
3- If you choose spatial mode you continue to hear the audio, but is not considered in scoring (the boys' names and girls' name version the sound is off when you choose spatial mode).
4- The game have 8 different sounds and 8 image positions like the original game, and not 9. Please see the working paper: http://www.pnas.org/content/early/2008/04/25/0801268105.full.pdf+html
