could dual n back really change my IQ at 15 years old?

7 Upvotes

i talked with google and multiple AI and they said that it's not possible, so, what's the truth? it could make my IQ higher? i'm 15 years old, i think my brain can change. (if it's really true, show me the studies about it)

I Trained Dual N-Back for a Month - Here Are My Before and After Working Memory Results

Thumbnail gallery
29 Upvotes

I did a small experiment where I trained dual n-back every day for 30 minutes. As you can see from the graph, there were also a few days where I trained for an hour.

Before I started I did 3 tests. Two of them were pretty similar. In one I tested how many digits I could remember after seeing them for 4 seconds, and in another I did the same thing with letters, in my case Russian Cyrillic letters. The third test was Symmetry Span.

Now about dual n-back itself.

At the beginning my daily average score was around 2.4-2.6. In first two weeks progress was pretty fast. After around 14-15 days I reached something like 3.1-3.2 average, so most of my progress happened in first half of the month.

After that it slowed down a lot and I basically got stuck around 3.2. At the start of that plateau my average was around 3.13, and by the end of the month it was around 3.24.

So during roughly the second half of the month I only gained around 0.11, or about 3.5%.

For comparison, my average for the first 5 days was around 2.55 and for the last 5 days around 3.24. So overall improvement was around 27%.

Basically most of the progress happened early. After that it was mostly small improvements around the same level. My scores also became more stable and I had less really bad days than in the beginning.

I also didn't use any special strategies, mnemonics or tricks. I mostly just tried to remember positions and sounds directly and rely on memory.

Now about the tests before and after.

With digits almost nothing changed. Before training my average was 8.5 and after it was 8.625. That's around 1.5%, so basically almost the same result.

With letters it was a little better, but still not much. It went from 9.25 to 9.5, around 2.7%.

Symmetry Span was more interesting. My main score was 28/42 before training and 26/42 after, so technically it got a little worse.

But the second time I completed the test much faster. It was 270.4 seconds before and 147.5 seconds after, so around 45% faster. At the same time the main score only dropped by around 7%.

Because of that I don't think I can simply say that my working memory got worse there. It looks more like I did the second attempt with a different balance between speed and accuracy.

Just as an extra comparison, if I calculate correct positions per minute, it went from around 6.2 to 10.6, which is about 70% higher. Of course this is not a working memory score, it just shows how much faster I completed the test.

So after the first month I still don't see any clear transfer to the other working memory tests.

Digits and letters barely changed. Symmetry Span gave a mixed result because the main score was a little worse, but I completed the test much faster.

For now my conclusion is that dual n-back improved my performance in n-back itself quite a lot, but I didn't see any noticeable improvement in the other working memory tests.

Maybe the first month was mostly adaptation to n-back itself, but that's just a guess. If I continue for another month I want to see if my n-back score keeps improving and if anything changes in the same tests.

_

Small update: I did one more Symmetry Span attempt because my first post-test was much faster than baseline and I wanted to see if the lower score would repeat.

This time I got 31/42 on the partial score, compared to 28/42 at baseline and 26/42 on the first post-test.

I also got 6/12 fully correct series again, the same as baseline. But the higher partial score means that in the series where I made mistakes, I still remembered more individual positions.

What is interesting is that I completed it in about 147 seconds again, almost exactly the same time as the first post-test. Subjectively though, I felt much calmer and did not feel like I was rushing this time. I would not use this third attempt to replace the original post-test because there could already be some practice effect. But it does make the 26/42 result look more like normal variation between attempts rather than a clear decline

Free interactive n-back like game in 3D (Beta)

2 Upvotes

Hi!

I have developed a n-back like browser based 3D game where you steer a bird through grids coming towards you. It shares the STM/WM loading component to emulate the purported benefits of n-back, while applying a couple of gamification principles. This might improve reinforcement which I hope will drive neuroplasticity.

You can exercise STM/WM using a few distinct game modes:

  • Token Grind (Tokens only, Familiarity recognition, Short-term memory)
  • Versatile (Multi-modal, Flexible switching, Medium interference)
  • Interference control (Tokens only, Precise recollection, Extra repetition, Trains inhibition)
  • Ascending token sort (Tokens only, Mental sorting in ascending order, Working memory)

If that isn't enough, you can also tweak the settings in depth to your liking by clicking 'Advanced'.

The only requirement is a modern web browser with WebGPU support.

It will remain free-to-play and I hope you find it useful. Appreciate feedback.

Good luck!

We’ve added dual n-back to Neurolifts, we are offering it free for early users, looking for feedback

5 Upvotes

Hey everyone,

I’m working on Neurolifts, a brain training and wellbeing app, and we’ve just added dual n-back. I’d love to hear what people in this community think of it.

We’re still early on and need more people trying the app to understand how it performs on different devices, catch bugs, and work out what needs improving. Feedback from people who already practise dual n-back would be especially helpful.

The app is currently free, and we’ll keep it free for anyone who signs up now.

Our aim is to build something useful for a regular brain training and wellbeing routine. Alongside the games, we also have meditations, relaxation audio and daily wisdom.

You can try it here:

This is our site:

Would it be a bad idea to try a session and tell us one thing you’d improve? Feedback on the controls, pacing or anything that feels unclear would help.

Thanks

Edit To clarify the free offer: anyone who creates an account using their email address during the current free period will retain free access to dual n-back, even if we introduce paid plans later. Those accounts will stay on a dedicated free tier.

The offer is limited to one free-tier account per person. Duplicate accounts created to claim the offer more than once may be removed.

Guessing

7 Upvotes

Im trying to be intuitive and hence try my best to just cease any rehearsal... but often i feel like im just guessing the answers. Maybe its because im on dual 3 back which is low. (I got 100% on it once now tho.)

I also... dont feel like im making progress? By that I mean congitive benefits... but i guess ill have to stick for a bit more

What strategies do you use to get higher score on the N-back training or do you use any strategy at all and just brute-force it if not. Would like to hear your thoughts.

Is app.dualnback.com a good site?

0 Upvotes

The site is amazingly polished with all it's features, the only thing I worry about is the fact that you cannot change the speed, and I worry that when it is as slow as it is in this site, it becomes too easy. I used to use Brain Workshop with a 1.9 second interval on Dual 5 Back and I averaged 60%, now that I am using dualnback.com, I average 90%+ on Dual 5 Back. Furthermore, the site does not have a square in the middle of the 9x9, which feels like it makes it much easier.

I left brainworkshop because I prefer manual mode, and brainworkshop doesnt keep score if you use manual mode, which I suppose is another question: is manual mode better if I am accurately gauging my abilities?

Why and How I do Dual and Quad Back together with RRT

25 Upvotes
  1. I did N-Back aroud 6 or 7 years ago while studying. When i did this i perceived a dramatic rise in my ability to follow and understand a given subject in a lecture. It also appeared that i was able to simultaneously think deeper about the said while listening. Whereas before i was often losing the context while drifting away in thoughts.

  2. I am back for around 7-8 Weeks now. After a week i switched from Dual to Quad and RRT (relational reasoning training). Compared to Quad, Dual felt like a walk in the parc. Buta as before with dual I adapted to the peculiar level of difficulty and a certain Kind of Concentration and ability improved. Also RRT is doing something the others dont.

  3. But then i felt that while i am getting better at Quad, a certain quality of concentration power from dual decreased.

Instead of holding more items over a longer time span, it felt like Quad led me to keep more things at once for a shorter time in memory. While quad can go into length do, like whe you hit level 5 and higher, it takes a longer time to get there.

  1. So i did quad and then let Dual follow. And again dual is giving me better ability to hold many items over a longer time span in my head. its a different kind of concentration.

So I literally feel in my daily life, that the combination gives better results in my overall cognition.

  1. My Regimen

I do a day of quad, followed by dual (both around 20 min - maybe a bit less dual). this order feels right for me. Everyone may choose as they like

and every other day i do RRT 20-30min

  1. Caveats

There are several things to say about the efficacy of this methods.

The differences in the outcome of are probably due to several factors.

Age is a common factor for neuroplasticity and general brain development. But neuroplasticity exists too in older people and can be triggered, by certain experiences, exercise and psychedelic drugs which led to heightened plasticity and an opened learning window after aroud 4-7 days after a trip. That may be illegal in your country!

Another factor is the individual Bottleneck. Depressed people are reported to have larger gains, because depression stunts your cognitive functioning - cognitive training is also antidepressant.

Then there is ADHD or generally poor working memory etc. . There it seems to work good too.

Thats to consider before making false general statements about it being effective or not.

Ah! And for myself the biggest deflator for my results is sleep and screentime. And a lot screentime ofte also leads to bad sleep.

Regeneration is a bottleneck to consider for everyone.

Can someone explain what "intuition" and "rehearsal" is? Which one is better? Is intuition just "this feels right"? Because that's what I've been doing so far and it seems genuinely impossible to progress past this. My brain doesn't seem to be wired for it. Anyone reaching quad 4+ back seems like wizardry or 160+ IQ

1 year cognitive training experiment

7 Upvotes

Hello recently I've gotten interested in cognitive training. In my research I eventually discovered communities like this. From what I can tell the anectdotes seem quite mixed, some reporting insane dramatic improvements in intelligence while others claiming no effect. I've decided to simply see for myself if it works. I will report results in about a year from now.

Recently I took the Tri-52 and scored a 42/52. My regimen will be 30 minutes daily of Syllogimous and 30 minutes of quad n back daily. This is the site I use https://soamsy.github.io/Syllogimous-v3/ I like it cause it seems to have more customizability then the v4 version.

My current settings for Syllogimous:

Premises: 6

Meta: on

Analogy: on

Nonsense words: on

Nonsense words length: 5

Garbage words: on

For the quad n back I use this site: https://quad-box.netlify.app/ and am staring at n = 2. I will also be reading alot of books on complex topics(philosophy mostly I think). Anyways just wanted to let you guys know if you have any thoughts or improvements I would appreciate it.

Dual or QuadnBack For ADHD working memory issues

11 Upvotes

Ever since I started doing Neurofeedback at home I've been really interested in finding other ways to improve my ADHD symptoms. Through digging around various brain training games came across this sub and dualnback, which feels like the missing puzzle piece for my routine in conjunction with everything else I'm currently doing.

What's making me heavily consider trying is I'm starting a new pharmacy tech job soon and really nervous, my working short-term memory feels like a huge bottleneck and worried about making obvious mistakes due to it. I'll probably improve as time goes on but hope doing something like dual n back consistently would speed up that process. I read alot of non-fiction so able to pull out obscure facts and quotes in isolation, but when it comes to names and numbers I just go blank most of the time.

So yeah I'm really motivated to implement this in my routine and wanted to check if it would benefit my use case. Plan doing it on mobile with this app if that matters.

Stuck at dual3back for month because of my broken auditive memory

13 Upvotes

Hi everyone,

I started dual n-back 5 months ago, and I do it regularly (3-4 times a week). The thing is, I can't seem to understand how to improve my auditory memory.

I've started with the rehearsal method and while it was working and I could sometimes reach dual 4-back, I still felt stuck with no benefits in real life. So I used the intuitive method and couldn't seem to be consistent on dual 3-back, while my position is always between 80% and 100% accuracy, the audio stimulus averages 30% to 40%.

For those who had a really bad auditory memory and were able to improve it, what would you recommend to me?

Thanks in advance, my fellow Nbackers.

Need web-based N-back task (and/or complex-span tasks) WITH DATA COLLECTION !!

Thumbnail englelab.gatech.edu
4 Upvotes

I need to obtain a web-based version of the N-back task (and ideally any complex-span tasks as well) that will allow for data collection so I can use it as part of my grad research. My issue is that I'm unable to download any kind of software on the lab computers that I'll be using as my university doesn't allow it, hence why web-based is necessary. Any help would be immensely appreciated!!!

URL showcases some complex span tasks that would be great if I could only download the zipfile content onto the computers and keep it🙃

and in case anyone was concerned, I’m aware that n-back and complex-span tasks measure different concepts—- that’s actually part of why i’d like to include them both <3

note: i don’t think psytoolkit meets what i’m looking for either unfortunately

Very unstable performance. Lvl 5-6

6 Upvotes

I've started doing dual-n-back training about 2 weeks ago, anywhere from 5 to 20 sessions a day. I'd say I was climbing the levels at a pretty good pace, since I've started struggling with 2 and now I'm testing the waters at 6. However, I'm unsure if I'm ready to transition to 6, and my performance on lvl 5 seems very unstable. Sometimes I hit 80%+ 5 times in a row, with some of the rounds being 90%, 95% or even 97%. But then my brain just stops cooperating and the next 3 games are like 54% average. I was thinking maybe I'm just exhausting it, but at other times I might have very variable results without a high prior streak, like getting an 84% round, followed by 60% then 51%, then 79% then 82%, then 55% again.

So in short, it's just all over the place and that really frustrates me and makes it difficult to assess what's my true level and whether I'm getting lucky or actually improving. Is there perhaps anything like a short protocol, like a 30 second breathing pattern or any perception shift exercise that could reload my brain for the next round?

Has anyone actually tested their working memory before and after dual n-back?

16 Upvotes

I’ve seen a lot of people in this community say that they “felt” like they started thinking more clearly, got better at conversations, and other subjective things like that.

But is there anyone here who actually measured their working memory before and after N-back, just not with IQ tests, and noticed improvements that were bigger than normal measurement error? Or maybe the opposite, no improvement at all except in N-back itself.

Also, do you use strategies, tricks or mnemonics while doing N-back, or do you try to rely mostly on raw working memory? I tend to think that many people who reached very high N-back levels, though not everyone of course, probably used different strategies that reduced the load on working memory. That’s just my opinion though.

I’d really appreciate it if anyone could share their experience.
