The term brain training is nothing new, however how effective is the 'N-back' method, does this work scientifically speaking?

There are mixed reviews on this: one claiming it works https://www.highiqpro.com/dual-n-back/latest-n-back-training-studies

Another it doesn't https://www.cambridgebrainsciences.com/more/articles/brain-training-still-not-vital

  • $\begingroup$ @JeromyAnglim Thanks for the link, the answer was explored in-depth. Much appreciated. My understanding is that N-back may increase fluid intelligence and relational frame may increase general IQ, correct? $\endgroup$ – user20629 Jun 14 '19 at 3:37
