There are many ways to improve cognitive skills. Nowadays it is possible to perform cognitive training using applications on smart devices; furthermore, it is possible to acquire these cognitive skills also through openness to experience and social connections. If you are a busy person and prefer to use applications during your free time, Lumosity is one of the best applications to train your brain; it will show you your progress which I think is a brilliant thing. Lumosity Performance Index (LPI) is where all your gaming scores are systematically calculated. This is where you can find all the cognitive skills present in the games you will train on: this will show you where you perform excellently, your improvements and where you struggle, where you need a little more training. From my experience with Lumosity, this program really helps me improve cognitive skills: speed, memory, attention, flexibility and problem solving. I learned new words that I may have never heard before, vocabulary builder; I get better and better at staying focused when my attention is divided, managing multitasking; and I can see progress in my problem solving, analysis and calculations. I can see where I'm improving and where I need to train more.
