That’s stupid, though. If you can explain 11% of the variance of some noisy phenomenon like cognitive and behavioral flexibility, that’s noteworthy. They tested both linear and quadratic terms, and the quadratic one worked better in terms of prediction, and is also an expression of a meaningful theoretical model, rather than just throwing higher polynomials at it for the fun of it. Quadratic here also would coincide with some homogenizing mechanism at the two ends of the age distribution.

Whether you’re right or wrong, starting your argument with “that’s stupid, though” is unlikely to convince many.

But I have eyes and the curve they picked as best fit is really poorly fitting. It’s such a poor fit that is almost in a dead zone of the random points.

Does that mean it is not true that it becomes harder to learn new things with age?
I’m 26 and I’ve been rushing gaining knowledge and experience very much so far for fear of just not being able to fit in much more once I reach certain age.
No I’m not virtue signaling, this is fucking stressful and I will be delighted to slow down a fuckton if that’s true.

From a completely unscientific but ‘experienced’ perspective I think the problem is that life just gets in the way as you get older, and you prioritize your own life rather than trying to learn.
Whether neuroplasticity means you can learn things later or not, the opportunity to learn things later just isn’t there without effort.
Having a job, kids, a mortgage and no social obligation to learn in a structured and organized way probably impacts you more than anything neurological.

I’d imagine it also has something to do with becoming less practiced at learning things.

Yeah, get in what you want because in twenty years the greatest thing your brain will enjoy is not processing anything of consequence.
Could you learn cuneiform and gain a rich understanding of 18th Century Viennese intellectual culture, if you didn’t know anything about that before? Sure.
*burp* But then you’ll be like “ah, gotta bring in the trash cans and then I can sit.”

As long as you continue to learn new things, then no, it doesn’t become harder with age. In fact, studies show that people who are lifelong learners can actually increase their ability to learn as they age. Learning, for example, a foreign language in later years has been shown to be just as attainable as in childhood, and might even give some protection against dementia. Your brain can actually become more plastic as you age if you continuously push it to do so, and it can actually become easier to learn if you train yourself to do so.
The idea that learning capacity diminishes with age seems to be a widely accepted myth (which may have roots in sociological and cultural biases), and the opposite may actually be true.

Well the ‘myth’ you speak of is based on the fact that the opposite of what you describe is also true. Those who lose any interest in learning new things become progressively more rigid and stuck in their mindset and become less and less likely to learn or adapt as they age. I suspect there are more people leaning towards that than lifelong learners, but I may just be a pessimist.

I’ve seen (and experienced in my fifties) that age does affect the working of your mind. I’d compare it to sleep deprivation. You know, when you’re young and reckless and haven’t slept well for a week, maybe pulling all-nighters for fun? It affects your concentration, your reflexes, and your general memory.
Age is like a mild sleep deprivation that gets a little bit worse each decade. It takes effort to stay lucid.
LillyPip@lemmy.ca 10 hours ago
I agree with you, but I wonder how much of this is that most of us are worked to our last nerve until we’re at least 65, so many of us don’t have the luxury to maintain our brain plasticity? Once we’re 70ish, if we didn’t have that opportunity when we were living hand-to-mouth, and our brains are kind of set by that point.
We all have the potential, but not the opportunity until it’s kind of too late?

I find that I get smarter as I get older, as stupid stuff that held me back gets discarded. You do have less energy I hear, but even there I think a fit 50 year old would be more energetic than a lazy 25 year old? Obviously having kids is a huge energy drain, but that’s not technically aging, just correlation rather than causation.
So anyway even if this graphic were true, it would be irrelevant as the major factor seems to me to be a willingness to learn, only after which raw ability would come into play.
In your case the adage that now is the time to learn is true, but not for any of the reasons mentioned above. Once you shift your perspective that the time for hard work is over and the time for personal play is at hand - to watch more TV, play games, hang out with friends, etc. - then it’s incredibly hard (most people phrase that as “impossible") to ever go back to that college mindset of “it’s study time, let’s go!!!”. That’s not even just human nature, but rather the raw physics of inertia coupled with adaptation that lowers energy requirements that were evolutionarily built into our brains and bodies.
Discipline is a mindset that is mostly independent of age, except it trends towards older as those who have seen how it works first-hand now realize its value (coupled with individual survival of those who have more rather than less of it, i.e. the most reckless die the earliest in life), plus also younger as people listen and thus benefit from the accumulated wisdom of others.

What has discipline got to do with it? I feel it’s pretty independent or may even get in the way of learning. If you force (discipline) yourself to learn something, it will feel much harder than if you do it out of joy. But maybe I didn’t fully understand what you were saying.

Neural plasticity isn’t exactly the same as learning but, yeah, there seems to be a thing around 27 where neural plasticity seems to plateau a bit.
But I’m wondering if that’s more the effect than the cause. Perhaps it’s because a lot of people, up until they’re around 25-30, have a very quickly changing life. Schools are changing, jobs are changing, people are changing. But when you start to get into late twenties, early 30’s, most people already have a routine of some sort. And it would seem logical to me that it could mean lowered neural plasticity.
And perhaps it could come just as well if you started having as much variance and stimulation as earlier in your life. Perhaps not as much.
But yeah I don’t think there’s any sort of biological limit that you just can’t learn things anymore. Never too old.

guess the correlation, looks about like a solid 0.1. Whoever put that regression line in there is crazy, the confidence interval is insulting.

How do you think a case of “this explains some of the differences in the population, but not a lot” should look?
And that looks potentially fine for an error bar. For a mean estimate, SE=SD/√N , so depending on what error band they used this looks quite plausible.

Also, the R^2 is even in the picture: .11

Was about to say that. It’s sad that your comment is the very last in this thread.
LillyPip@lemmy.ca 7 hours ago
1: it’s not last, and 2: it’s not sad, because 3: people aren’t reading the source material. I love xkcd, too, but that doesn’t apply here.
We don’t need to throw satire pies in the just because results don’t match expectations doesn’t mean we should throw pies of satire in their face. This is actually interesting.

What is this, a black swan event you could not have predicted as being within the realm of possibility, and thus have no idea how to react?

But we know for a fact that plasticity does drop with age, that’s why it’s so difficult to learn foreign language after childhood.
