Dual N Back Results

Hey guys, I wanted to share my write-up on Dual N-back. It includes the science behind DNB as well as my personal results. 

I don't have any hard data to back up IQ gains, but subjectively, it feels like I'm about +5 IQ points better for it, Lol.

Dual N-back is a deceptively simple looking brain game that is scientifically proven to:


 


  • Increase concentration
  • Boost working memory
  • Increase fluid intelligence

Working Memory = Fluid Intelligence = Cognitive Ability


 


"Working memory" is interchangeable with “fluid intelligence.” Fluid intelligence is a good predictor of general cognitive ability.


 


It underlies many activities you might do on a daily basis:


 


  • Mental math
  • Reading and writing
  • Conversation
  • Memory
  • Learning new skills

 


Quantified Benefits


 


Working memory gains from Dual N-Back proved to be linear in this study. As the numbers show, the more you train with Dual N-Back, the more benefits you reap.


 


Neuroscience


 


Working memory training = more general cognitive ability in mice. More specifically, these challenges enhanced the Dopamine 1 (D1) receptors in the mouse brains. There’s definitely some correlation between D1 receptors and mental health.


 


Anecdotal


 


Dual N-Back has varying levels of difficulty. Everyone starts out on level 2. I played at least 3 games per day for 31 days. 


Here were my average scores by the week:


 



Week 1 Dual 2-Back (90% accuracy)


Week 2 Dual 3-Back (60% accuracy)


Week 3 Dual 3-Back (80% accuracy)


Week 4 Dual 3-Back (90% accuracy)



 


The results I noticed seemed minimal, at first. But then I realized I wasn’t forgetting what I was going to say in conversations. I didn’t have trouble focusing. I could quickly process complex thoughts and memorize long sentences.




After taking a week off, I came back to the game. I expected at least some atrophy of my mental abilities.





To my surprise, Dual-3 Back seemed so incredibly natural that I had to bump up the challenge level to Dual 4-Back. Allowing a “recovery week” seemed to enhance my gains even more! 





Your mind is a muscle- use it often, for good things.
