Another theory on WM and intelligence

[Anon]

Basically speed of working memory = speed of thinking (but there are some obvious exceptions of course. Example: when a word is on the tip of your tongue. In this case, the speed of recall from LTM is limiting. Or when you came up with the perfect counterargument a few days later. But these ones are really specific).

So probably you can say that in many tasks WM speed (speed of updating WM and speed of recalling from WM) ≈ thinking speed.

Apparently John von Neumann had one of the fastest WMs in history.

Don't take too seriously, it's just one of those 3am thoughts

Also, if you played cognitive flexibility games like "All you can E.T.", you might have noticed that your performance in these games is basically made up of 2 things:

1) WM speed

2) Inhibition, which you need to not choose wrong button reflexively

(of course, the speed of perception also affects, but I think for most people it is not a bottleneck in most of such tasks).

In some CF tests you mainly need high WM speed, in others (Stroop test) you need good inhibition.

Surprisingly (not), both WM and CF mostly depend on dorsolateral prefrontal cortex. Btw, Inhibition also depend on DLPFC.

So WM speed may be as important part of intelligence as WM capacity. And WM speed is a really big component of CF.

True, he could do crazy mental computations. I think also just practicing mental math, as simple as it might seem is a good way to flex WM speed and manipulation especially with some time pressure on it. I have mixed it into my routine along with. Dual-n-back, meditation, studying math, and other brain training games. I do 1 hour each day and try to just overload my g. Some days I do Lsat other days gmat, etc. i think you need to stimulate with a lot of different activities to really hit G from all angles.

Yes I agree as well. And WM speed is not talked about often, only capacity.

That's why I put dual-n-back trial time at (sub) 1 second because it forces you to update faster. The capacity load will still remain almost the same.

Working memory speed will also help with reading and especially talking fast(yet coherent)

I see. I was unable to do sub 1 second so I stick to 2 second rn

If you are interested, today I made a simple minimalistic python program for math training. I found a dataset called "GSM8K" (Grade School Math,  >8k tasks) and made game with 3 modes: speed mode, endless mode and most hardcore - memory mode. In speed mode you need to correctly answer 10 questions as fast as possible. Program uses your stats in this mode to make 2 plots (check screenshot). Endless mode is ... well, endless. Memory mode is a mode in which every next word appears only after previous disappears; you starts with base speed of 1000, which increases by 25 each times you answer correctly and decreases by 50 each times you answer wrong. After 10 tasks it ends and new base speed saves.

This game is both speedreading and math trainer. It will allow to train speed of understanding the text.

I used this dataset just for test, I want to make somewhat similar but with more serious math tasks with many ranges of difficulty including olympiad level, so that as you progress in solving the problems, the difficulty of the problems increases. And with many fields like number theory, combinatorics, probability theory, geometry, algebra, calculus etc. So you can track your rating separately in different fields.

There are 2 files in this rar archive, one is json dataset (so if you want to see the solution or want to delete some poorly formulated problem, you can do it), other is main.py file which you need to run to play this game (unfortunately I don't have web development skills yet, so I implement my idea using pygame)

This is what memory mode looks like

Oeps this one: 
https://www.preplounge.com/en/mental-math

I'm also a lot on: https://humanbenchmark.com/

I think playing warcraft 3 or starcraft 2 is a good idea. Especially warcraft 3, you need to be focused the entire game, use finger dexterity, make high level strategic decisions and each game is different and fast paced. 
The act of you learning the game is also a brain training. But beware very addictive game. I would mix it in with other games, like chess (and particularly chess puzzles) and polytopia (also fast turn-based strategy)

I upgraded the game.

Changes:

1) First of all, I changed number of tasks in speed mode and memory mode. I realised that 10 is too much, now it's 5.

2) I added new button 'History', which you can click to see every task you did with problems, your answers and right answers

3) I turn all of it into exe file, so you can launch it immediately after downloading on any PC without installing Python and libraries

https://www.virustotal.com/gui/file/2e6e5c939c1dc8b43b4e7e7be5cf4b6da977f239e0d24f9d3b46309fcb04141e/detection

(Unfortunately there are several false positives that virustotal gives to all exe files built with pyinstaller)

2 options:

1) Download as exe file https://drive.google.com/file/d/1gzs08SOUP770OU8yAkKSpThz1mS9uRZS/view?usp=sharing

Super fast and simple, you don't need to pre-install anything.

2) Download rar archive and run main.py file

So you can edit anything you want, even completely change dataset of tasks. Also you can use this option if you don't want to download exe file from some random guy from the Internet, which is pretty reasonable lol :D
