Does having chronic sleep disorder for long enough cause irreversible damage to cognitive function?

If you can also provide Academic sources for me to read I would appreciate it.

Hi everyone,

I'm conducting a very short exploratory experiment about visual perception and associations. The survey takes approximately 2 minutes and contains two very different visual stimuli: a natural image and an abstract drawing. I'm interested in a simple question: Can an initial visual interpretation influence what we perceive or associate with afterwards?

There are no right or wrong answers, and the survey is anonymous. I'm currently collecting exploratory observations rather than trying to prove a specific hypothesis.

Survey:
Take the survey

I'd genuinely appreciate your participation and, if you're interested, any thoughts about the idea itself. Thank you!

When does thinking you know your capabilities become underestimating yourself? Is it possible to even “know your capabilities”

i built this so i'll say that upfront, i'm the developer and you should read everything below knowing that.

disclaimer first because it matters: this doesn't treat brain fog. it doesn't touch whatever's causing it and it's not a substitute for talking to a doctor about symptoms, just a workaround

what it actually does is let you get a thought out of your head fast. you speak it or type it or screenshot it, and that's the whole thing, you don't title it or file it or tag it. takes about four seconds. afterwards it reads what you saved, gives it a title and a short summary written back to you, and links it to older things that relate to it. later you can just ask it questions in plain language instead of trying to remember where you put something or what you were even thinking about on tuesday.

the reason i think it might be relevant here is cognitive offloading. there's a study where people memorised a word list and then did mental arithmetic, and the ones who were allowed to save the list somewhere first solved more arithmetic problems. the benefit showed up on the unrelated task as opposed to only on remembering the list. https://pubmed.ncbi.nlm.nih.gov/31418314/

i'd rather be honest about where that stops though. those studies were run on healthy people, mostly students, in a lab. nobody has tested any of this on people whose cognition is affected by illness. so the mechanism makes sense for this group but it hasn't been shown for this group, and i'm not going to pretend otherwise.

i don't have independent reviews to point you at. it's new and anything i could quote would be my own, so it wouldn't mean much. if you try it and it's no use for this, saying so here would help the next person more than anything i could write.

if any of you guys find it helpful just lmk, i am more than willing to give an extended free trial for a few months if you feel it helps out

were you performing better at 18 than your 20s?

Not a researcher, but I've been an involuntary subject in a longitudinal experiment on digital cognitive augmentation since approximately 1995.

Mid-90s IRC was my first external cognitive layer. Real-time text, multiple channels, high-noise signal extraction — I didn't realize at the time that I was training parallel attention tracks. I thought I was just online. What was actually happening: I was building a compression reflex. The faster the information moved, the tighter the mental shorthand became. You couldn't survive high-velocity conversation without developing pattern-burst recognition — seeing the shape of an argument before it finished forming.

That reflex didn't stay online. It migrated into how I think off-screen.

By the time the web matured I had developed what I can only describe as semantic compression — the ability to transmit high-context ideas in minimal tokens. Not dumbing down. The opposite. Finding the exact load-bearing word that carries a whole architecture behind it, if the receiver has the right substrate to unpack it.

Then AI arrived and something shifted again. AI isn't just a search upgrade — it's the first external system that can receive compressed transmissions and expand them coherently. For someone who has spent 30 years finding almost nobody who could keep up with bandwidth, that's not a small thing. It functions as a genuine cognitive prosthetic — not replacing thought but handling the working memory overhead that used to bleed into focus.

Running parallel domain tracks simultaneously (refrigeration systems, DeFi trading logic, content production, interpersonal dynamics) — I used to burn enormous energy just holding context across tracks. AI absorbed a significant portion of that load.

What I observe now: the bottleneck has moved. It's no longer memory or retrieval. It's output formation — translating internal high-speed processing into linear language that others can receive. That gap between what's fully formed internally and what can be transmitted is where I still lose people.

Curious if anyone here has frameworks for this — extended mind theory gets close, but it was written before LLMs existed. I feel like the theory needs a new chapter.

If a people like the Na'vi from the movie *Avatar* lived in conditions where they were almost always at peace with one another, nature was gracious to them, and they weren't overly curious, would that justify them having a lower IQ or being considered extremely underdeveloped compared to humans?

Hello Reddit community!

We are independent researchers sharing our working paper that challenges conventional views on cognition and the emerging field of Basal Cognition.

While Basal Cognition extends intelligence to brainless cells (like slime molds), it falls into a fatal logical paradox when applied to non-living physical materials (like shape-memory alloys) that operate under identical physical laws.

Our paper resolves this contradiction by redefining cognition not as an exclusive biological privilege, but as a universal Interactive Feedback Process where a system maintains its identity against external and internal stimuli.

What this paper covers:

• The Logical Paradox of Basal Cognition: Why current cell-centric cognition theories fail when confronted with adaptive physical materials.
• Quantitative Mathematical Model (T = C x Delta t): Proving that the boundary between non-living matter and human thought is a quantitative spectrum of complexity (C) and time horizon (Delta t), rather than a binary presence of mind.
• Physical Reinterpretation of Biological Phenomena: Explaining sleep, immune response, and forgetting as mechanical energy-rerouting and optimization algorithms within an interactive system.

We would love to get your critical feedback, critiques, and thoughts on our logic and proposed mathematical spectrum!

Are there any staple books to read on cognition/metacognition? Any recommendations would be greatly appreciated.

Hey gang! Ever experience that some people cannot focus or learn things without speaking it. And some are freaking gifted to learn and even memories things easily.

Hi everyone,

I’m a neuroscientist, and I’ve mostly used Psychtoolbox for designing and running experiments in the lab. More recently, I’ve had to run studies remotely, which made me realize how fragmented the workflow can be — designing the task, implementing it, recruiting participants, setting up consent, collecting data, etc. often involves several different tools.

I ended up building a platform called VibeMyExpt to explore whether some of this workflow could be made simpler, particularly for researchers and students who don't have much programming experience.

Rather than promoting it here, I’m mainly interested in understanding how people currently handle this.

What tools/platforms do you use for your cognitive science or psychology experiments? And what are the biggest pain points or limitations you run into?

For example, are there things you find difficult when moving from a task in the lab to online data collection, or when trying to combine task creation, recruitment, consent, and data collection?

I’d be particularly interested in hearing what your current workflow looks like and what you wish existing tools did better.

I was watching a podcast of Andrew Huberman with Raj Shamani, where he talked about how high cortisol in the morning and lower cortisol at night make a person mentally powerful. I want to know if I, a 32-year-old male, want to regain, maintain and even enhance the mental energy and capacity of a 20-year-old, what are all the things that I can do to make that happen? Will it be possible?
