A recent study in the Proceedings of the National Academy of Sciences found that a particular memory game called Dual N-Back may actually improve a persons short term memory. The study indicates that by regularly playing the Dual N-Back game, it may be possible to increase almost anyone’s IQ (or more accurately, gF), which was previously thought to be unchangeable.
The Dual N-Back game involves remembering both a sequence of spoken letters AND a sequence of positions of a square at the same time, hence the term “Dual” in the game name. The “N” refers to how many sequences back you remember.
