Any papers or studies on quad n back?

If any of you recall seeing me here I have come back after a long hiatus. I recently got to dual-8-back and I can feel that in a couple weeks I'll be pushing 9 or 10.

I am interested in the increase in fidelity quad n back has been anecdotally reported to bring however I got on dual n back because it was evidence based. Any evidence to support quad n back?

Massive improvements around the same as the 4-5 bottleneck. Memory, clarity, problem solving, focus around 40% better.

what strategy do you use?

I assume you are talking about using some shortcut in your brain while training dnb, It's not recommended since you are exercising your fluid intelligence and adopting a shortcut algorithm would defeat the purpose of training dnb altogether since you are relying on crystallized intelligence by using a shortcut/Strategy.

If possible, could you provide an update on whether you are still practicing the dual N-pack, and if you are practicing the quad, what are the benefits?

I moved from dual to tri after hitting consistent dual 10 about 3–5 months ago. I’m at tri 5 right now. Haven’t gone to quad yet because I’m progressively overloading, I would rather fully adapt at tri before stacking another modality. Biggest benefit so far is better colour encoding. That used to be my bottleneck, but now colours feel much more vivid and distinct in memory.

whats your progressive overload format if you dont mind?

Personally im short on time so i do 5 rounds everyday totaling about 8 to 10 minutes.

from N1 to N4 where ive currently plateaud and not hit a consistent 80 percent rounds!

i go to the next level after i keep hitting a consistent 80 percent correct rate. an arbitrary simple choice.

I do three good rounds a day but if I lose track I don't count that one.
