Improve your fluid intelligence with BetterBrain Lite.
Fluid intelligence is your ability to reason and solve new problems independently of previously acquired knowledge. With BetterBrain Lite you practice a challenging memory task where you have to remember simultaneously audio and visual events. A scientific study has shown a positive effect of this training on the fluid intelligence of a test group.
The memory task you need to practice is the 2-back task where you must remember the letter you heard two steps back in the past and simultaneously the position of a square on a three by three grid.
