The posterior hippocampi of average-IQ adult subjects who passed the difficult Knowledge exam for London taxicab drivers showed significant enlargement as opposed to before they began studying for it. The posterior hippocampus is associated with memory and spatial reasoning, both of which are strongly correlated with IQ. Similar effects not observed in the control group or in those who failed. Pic related.

This was actually a repeat experiment with a larger sample size (n=88), i.e. the results are predictable and reproducible. Pilot study in the citations. All subjects were fully-grown adults age 30+, so "normal" brain development had already run its course.

Thus we have hard, reproducible, undeniable evidence that the brain is capable of PHYSICALLY restructuring itself in response to focused training, much like a muscle.

So, lifelong neuroplasticity is true.

This doesn't settle the nature vs nurture debate, as the authors note:
>Although our data show that environmental stimulation can drive structural brain changes, it may be that this hippocampal plasticity expresses itself only in certain individuals. The trainees that qualified may have had a genetic predisposition toward plasticity that the nonqualified individuals lacked.

Also interesting: in a separate but related study, the authors gave a battery of cognitive tests to the same subjects. They observed an increase in spatial reasoning scores, but this was accompanied by a decrease in other scores! In other words, it's as if they "traded" one facet of intelligence for another...

Just when the thread was getting beyond boring with just one coping anon trying to argue purely via rhetoric and fallacy, finally, a real post.
Thank you. It's a very interesting paper. I'd like to see more study in this direction.

To solidify the link between race and language will require at least one more study.
Here's the logic. We have strong evidence the brain physically restructures itself in response to the tasks it is presented.

The posterior hippocampus is associated with memory and spatial navigation, both of which are strongly correlated with g. Similar effects not observed in the control group or in those who failed.

This was actually a repeat experiment with a larger sample size (n=88), i.e. the results are predictable and reproducible. And this was in subjects who were already fully grown (age 30+), so typical brain development had already run its course.

This was actually a repeat experiment with a larger sample size (n=88), i.e. the results are predictable and reproducible. You can find the pilot study in the citations. Oh, and all subjects were fully-grown adults age 30+, so their "normal" brain development had already run its course.

This means we have hard, reproducible, undeniable evidence that the brain PHYSICALLY restructures itself in response to focused training, and so it can physically become more capable of performing tasks associated with high IQ. Therefore, you can actually become smarter.

The posterior hippocampi of average-IQ adult subjects who passed the difficult Knowledge exam for London taxicab drivers showed significant enlargement from before they began studying. The posterior hippocampus is associated with memory and spatial navigation, both of which are strongly correlated with g. Similar effects not observed in the control group or in those who failed. Pic related.

This was actually a repeat experiment with a larger sample size (n=88), so the results are both predictable and reproducible. Pilot study is in the citations.
All subjects were fully-grown adults age 30+, so "normal" brain development had already run its course.

Thus we have hard, reproducible, undeniable evidence that the brain PHYSICALLY restructures itself in response to focused training, even in old age. Intelligence, being a manifestation of the brain's organization, is malleable.

Yes.

The posterior hippocampus is associated with memory and spatial navigation, both of which are strongly correlated with g.

Similar effects were not observed in the control group or in those who failed the exam (likely because they didn't study hard enough). Pic related.

Subjects chosen were fully grown adults so normal brain development should have ended long ago. Also, this study was a repeat experiment of an earlier pilot study, only with a larger sample size (n=88), proving the results are both predictable and reproducible.

In summary, we have reproducible, hard evidence that the brain PHYSICALLY restructures itself in response to focused training, even in fully grown adults. Therefore, intelligence, being a manifestation of the brain's organization, is also malleable.

>So IQ doesn't change no matter how much you study or how disciplined you are?
It's been proven by longitudinal fMRI that the brain's organization is malleable and adapts to complex mental tasks when trained, even in "fully-grown" adults in their mid-late 30's.

Very similar to the way the nervous system develops in weightlifters to recruit more muscle fibers.
So it stands to reason that one could intentionally develop the neural connections associated with increased g.

This is hard evidence that the brain PHYSICALLY restructures itself in response to focused training.
Therefore intelligence, which is a manifestation of the brain's cellular organization, is malleable and can be improved.

Which is what you will now resort to rather than refuting the above article and pic related.

In short, because intelligence is malleable. Those who aren't getting any attention from girls spend all their time studying, thus increasing their reasoning ability and IQ.

So we have hard, physically-observable, causally-linked, reproducible evidence that the brain PHYSICALLY restructures itself in response to focused training. Since intelligence is a function of brain organization, it must therefore be possible to increase intelligence just as it is possible to decrease it.

Intelligence (which is a manifestation of the brain's organization) is malleable. You become smart by doing math and science, not the other way around. You can physically alter you ability to grok proofs, perform experiments, recognize patterns, and write papers.

tldr: The posterior hippocampi of average-IQ adult subjects who passed the difficult Knowledge exam for London taxicab drivers showed significant enlargement as opposed to before they began studying for it. Pic related. Similar effects not observed in the control group or in those who failed.

This is hard evidence that the brain PHYSICALLY restructures itself in response to focused training.
In other words it appears that intelligence (which is a manifestation of the brain's organization) is in fact malleable -- and we see that with practice, you can alter you ability to grok proofs and experiments, write papers, recognize patterns, and so forth

>>9693414
So neuroplasticity is genetically determined now? Seems like that would be an important aspect of what we call "intelligence." Does g take it into account, I wonder?

>Considering it fits with what the authors wanted to see, it's probably entirely fraudulent.
We can apply the appeal to motive fallacy to "discredit" literally any study. How about we try the facts and logic thing instead?
>These idiotic attempts are tiresome to read.
I see. So you save your energy by refusing to read?
