Visualised it and my brain believed I had 10 arms for a moment, then tried to move them and it feels kind of like moving the the toes on your feet, just a bit easier actually. Yeah I can somewhat keep track of my 10 hands at the same time, what I can’t keep track of is the different colours of objects they each have at the same time on each finger, if they are different. Feels kind of creepy to have 10 hands at the same time if they are sticking out of your back. The evidence that my brain believed it for a moment is the fact that the sensation was creepy, It feels like you are moving multi layered worms inside your back.
Seems it is not that easy but perhaps what you are implying is that by constantly being under the requiring strain to have to keep more in your head at a time by employing your working memory you will get better at it, particularly if you are using many different regions of your brain in conjunction to this.
You know, when I was younger I once questioned working memory while looking at the board copying down what the teacher was telling us to copy down. I asked myself the question of why do I keep looking down then back up at every word if I can just remember a chunk of words and then write them down, surely this would be quicker? There isn’t any reason to pick the easier route when it involves so much mindless cross referencing, so I did just that. I then began to question why I could only keep so much in my head at a time when I can obviously read it, being my naive kids head at the time I tried to double this and realised that by repeating it a few times in one way or another I was able to do this. Around a week later or rather 4 days later, I became able to easily maintain double of what I could maintain in my head at a time. With some repeating it was making 4x my working memory doable to some extent. The strain from keeping 4x the amount in my head was kind of higher and I was satisfied with the results so I stopped doing this. By the end of the year it dripped back down to what it was originally.
Being older I naturally attempted this again but I didn’t have the same success. Then a few years ago I had to spend some time learning quite a lot in a day, I learned likely the most I have ever had in a day for pretty much over 16 hrs straight of learning under pressure. The day after that when I woke up my working memory had effectively doubled. Having gone through this hurdle I didn’t continue it and decided that I may as well rest a lot more for the next few days so I did this and my working memory quickly went back to what it was before that. A few months ago I tried a few experiments to get my working memory to go up a bit and in a strange sense I had some success with barely any practice, something along the lines of doing 3 repetitions and going to bed to have the boost for the next day( to note I have tried a lot before that but didn’t have success so much).
I will also note that by working memory in the above cases I am referring strictly to verbal working memory, except when I mentioned the day I spent in excess work, the limited days post this included both visual and verbal working memory being heightened to some extent.
Yes but it may not really be higher at all, might be lower. Centipedes don’t even have language in the same way we do.
For example, if I look at a large page of a book, I can recall it perfectly , I would love to claim this to be photographic memory but… I can’t read it even if I can recall it. It just looks like a bunch of text I can’t identify, the only thing I can really identify is the structure. So how many objects am I recalling? In truth around 1 object that has a pattern of squiggles in the middle and its structure to some extent. When I can track a full sentence or two in my working memory verbally, centipedes likely also have their own cheats to moving their up to 100 limbs, you know like “move their legs in a wave-like undulation along their body propelling themselves forward (or backward!) against the substrate”. As oppose to their legs all doing different things at the same time.
