I use (dual) N-Back as a form of cognitive enhancement. Here is my progress for the month of January. I’ve started doing also one triple N-back exercise—Position + Image + Sound N-Back.
As you can see, I was somewhat lazy during the first part of the month. However, it is quite interesting how fast all the curves grew between 16/01 and 20/01. It could be due to various reasons, perhaps because I started taking Coenzyme Q10 as a supplement.
