Improve your intelligence and working memory !
The n-back task is a continuous performance task that is commonly used as an assessment in cognitive neuroscience to measure a part of working memory and that has been suggested as a method for increasing fluid intelligence (Gf).
You will be presented with a sequence of stimuli. The task consists of indicating when the current stimulus matches the one from n steps earlier in the sequence.
This app is highly configurable (up to 4 simultaneous stimuli, nback level up to 6, speed...)
