    Default Countering the introverted tendency with brain training??

    You know how genuine introverts (i'm not talking shy people, I mean the neurological kind) are introverts due to the fact that they completely freak out with too much stimuli? Generally this is why I think I'm moving towards the INTP camp rather than ENTP: because although I sometimes hold/held ENTP tendencies (all of which will be gone by the time i finish this thread), I freak the fuck out during a disco and social events tend to be draining. Apparently this is due to the higher-state arousal that we introverts have in our PFC. Thus it sucks the life out of us to process all that information over time.

    I've thought of a mild counter to that tendency: give us more processing power.

    By that I mean literally training the brain so that it can handle more things at once and flip through them more effortlessly. have you guys ever heard of n-back?

    Brain Workshop - a Dual N-Back game
    Dual N-Back, Brain Training & Intelligence | Google Groups

    N-back is basically a game where you're supposed to remember a bunch of periodically flashed stimuli, n times ago. It's kind of like playing Snap/Match, except much more hardcore.

    The major boon given to n-back is the supposed fluid IQ increase (think basic smarts rather than knowledge application) that you get by improving this so called "working memory". Overall, the link between the two is sketchy, but it wouldn't hurt to have more of it. People have reported numerous benefits, like greater motivation, easier to tackle problems etc. The ones who reduced the trials between stimuli to less than one second report getting more "processing speed".

    I figure that if we work on making processing and thoughts more "effortless", then we can more easily process the external environment and then everything else just becomes superficial habit changing. Of course, this could completely backfire, because we're actually sending MORE blood/activity to the pre-frontal cortex, so we could actually become MORE pensive :p meh.

    PS remind me never to write stuff after an IQ test, I'm fagged

    Wow, now that's the kind of analysis I'd expect from an INTP!

    Good luck with your brain training and countering your introvert tendencies, but I do hope that you realize that introversion is not just about processing more things faster. It's very much about taking an genuine interest in the world around you rather than the one inside your head as well.

    Very interesting. I'm slightly confused though that there would be more activity in the prefrontal cortex of an introvert as opposed to an extravert. Or are you saying that it the pfc of an introvert can't handle as much processing as that of an extravert? My knowledge of neuroscience is very limited, but this sounds like an interesting idea.

    Extroverts have more blood flowing to their senses rather than the prefrontal cortex. Introverts can handle more information, but it tends to be a bit more internalized.

    So I'm wrong. As far as I know, N-Back training activates the PFC and results in dopamine receptor neurogenesis there, rather than the mesolimbic pathway.

    I see. Well, that makes sense. I can definitely attest to having a disconnect with the world around me. I'd have thought this was true for all NTs though, not just INTPs and INTJs. Maybe it's true to a lesser degree for ENTPs and ENTJs?

    I love that idea and analysis.

    And maybe a nutritional approach, too... here is my musing.

    NOTE: I am not a doctor and I am not and will not be responsible for any effects of this should anyone bravely/foolishly try it. I don't recommend anyone try this without consulting a medical authority. I hear toying around with dopamine levels can cause serious problems (trigger seizures, etc.)

    I read somewhere that introverts have a lower tolerance for dopamine than extroverts do. So if you could theoretically consistently expose yourself to a gradually-increasing level of dopamine, you could build up a tolerance level to that of extroverts. And this would make you more neurologically similar to extroverts.

    To increase dopamine levels, one could eat more foods containing L-Tyrosine. Levels also increase by activating the reward circuitry of the brain - so engage in lots of indulgences. Eat sweets, listen to loud music, have sex, etc. Done consistently, but gradually, you'll get used to it. Kind of like how a constant noise just becomes background noise, and you'd suddenly notice and be uncomfortable with the relative silence if it stopped.

    Now this begs the issue of correlation =/= cause and chicken or the egg conundrum, but that's my thought.

    Hmm...notice that stereotypical extroverts are ALWAYS engaging in primal fun. They could've been training themselves without knowing it.

    (Now I wonder...maybe pregnant mothers who live in noisy environments (while pregnant of course) are more prone to give birth to extroverts? Just because of the stimulation-dopamine effects?)

    And now I sound like a total crackpot. *puts down the pipe*

    I just realized that I can't stand chocolate, it's too rich. I wonder if that's any indication of anything.

    Do you feel calorically guilty for eating rich foods, or do you genuinely think it tastes gross?
