Genetic Glitch May Prevent Kids From Learning From Their Mistakes 500

jamie pointed out an interesting piece being featured in Newsweek that claims a "genetic glitch" may prevent some kids from learning from their mistakes to the same degree as others. "If there is one thing experts on child development agree on, it is that kids learn best when they are allowed to make mistakes and feel the consequences. So Mom and Dad hold back as their toddler tries again and again to cram a round peg into a square hole. [...] But not, it seems, all kids. In about 30 percent, the coils of their DNA carry a glitch, one that leaves their brains with few dopamine receptors, molecules that act as docking ports for one of the neurochemicals that carry our thoughts and emotions. A paucity of dopamine receptors is linked to an inability to avoid self-destructive behavior such as illicit drug use. But the effects spill beyond such extremes. Children with the genetic variant are unable to learn from mistakes. No matter how many tests they blow by partying the night before, the lesson just doesn't sink in."

      Perhaps, perhaps not.

      Consider that many kinds of sociopathy have the same kind of behavioral characteristics, but also include lack of guilt, inability to love, and parrotting of a number of emotions.

      Correlation != Causation, but the relationship of risky behaviors and inabiity to learn from many kinds of mistakes also typifies the pathology of sociopaths.

        Sex trumps survivability most of the time. If an organism survives long enough to reproduce, its line carries on.

        I know some people who are dumber than boxes of rocks, but they have lots of kids. Even if all the kids don't survive, some do. One woman I know has fourteen kids, thirteen still alive. She beats me at the evolution game thirteen to two.

      Not to mention heroin overdoses. There is no such thing as an overdose - opiates are relatively non-lethal - especially for junkies, who would never be able to afford ten times their normal dose (the minimum it would likely take to kill someone) at prohibition-level prices. In reality, heroin "overdoses" are almost always a result of an addict taking the drug in combination with alcohol, benzodiazepines, or who knows what else, either voluntarily or involuntarily. But even the voluntary ones might not be so voluntary - addicts might substitute these other far more dangerous drugs because heroin is unavailable, not because they would take it as their first choice. Not to mention that even these deaths by combination of drugs are slow and can be easily reversed with a Naloxone pen. Do a Google search for "heroin overdose."

    Sounds like ADD to me. I've got ADD and although I'm very intelligent, I haven't been an 'A' student since freshman year of high school. I can learn things well, but I continue the same behaviors that prevent me from succeeding, such as reading Slashdot (among other things) instead of doing homework.

    I took Adderall in school, which I believe stimulates dopamine and does indeed make it easier to do my homework. Also makes me test positive for meth, tell jokes that don't make sense to anyone but myself, and sleep 5 hours per night.

    I was going somewhere with this post, but as usual, I got distracted. Anyway, I hope this perspective can inform someone or at least make the other folks with ADD feel like they're not alone, even when so many people don't even think ADD is real.

        Give yourself structure. Make yourself a list of things you need to do every day. You could use paper, or be like me and get a $100 Palm Pilot. To me, mine is worth every penny. My list includes showering, walking the dog, getting haircuts, going to job interviews, getting my car inspected, paying my taxes, and pretty much every other thing I need to do.

        Other things are make sure your hygiene is good. Shower every day if you can. Get exercise. Ride your bike for half an hour every day, if possible. I've really taken a liking to cycling and it's helped to put my life in the right direction and help my lose lots of weight. Eat an egg for breakfast everyday; it'll make you feel good. Don't eat junk food.

        Keeping your body in shape helps you think more clearly, and the running theme is here that providing yourself with structure and goals is the best thing you can do for yourself this side of medication. I swear that giving myself some structure is the only reason I was able to graduate from college on time and the only way I'll succeed in making my career go somewhere and being the husband my wife deserves.

    I'm not surprised anymore at articles such as this one. Our DNA is basically a blue print of who we are. Our limitations, strengths, etc...

    While we are also a product of our environment, it's interesting to see how as we move forward in the research of the human body and mind, many of our issues which we would have deemed "environmental", are actually genetic.

    So, the question is, can we fix this? And then, if we fix it, are we a different person? or just better? Is our individuality really based on our DNA? what does that make of the human soul? Not a religious person by nature, I do think there is a God, but, I believe that humanity has the right and the responsibility to learn as much of itself as possible, in order to survive and to improve as a species.

    To me, an interesting question that raises is about our soul, such as, is our individuality link to it? or not? Having read and seen documentaries that a person on their death bed loses weight as they migrate from life to death. Many believe that our "soul" has a quantitive weight.

    Who are we? If one could fix a learning disability by "re-wiring" our DNA, then, what's this "soul" thing to us?

    Could it be that really, our version of heaven is actually our ability to learn about ourselves to the point where we can engineer our own immortality?

    After all, for many, heaven is a blissful eternity of life after death. That's what many religions sell in their brochure :P (I said MANY, not all)

    Is our goal to achieve long life by understanding our DNA? is this really what our reward will be? our quest for immortality lies within our reach in research and understanding of ourselves and what makes us really tick? :)

    This thread may sound off beat to the topic at hand, but, I personally think it that there is a link.

    Being able to fix a person by DNA so that they can finally "learn" from their mistake, is a behavioral fix. Done using medical treatment. To me, this means that there could be a day where "Psychology" as we know it might actually end, and DNA fixes could actually be the cure to depression, etc...

    Cheers!

        One of the strongest and most counterintuitive findings in this nascent field is that children with a sweet temperament, which is under strong genetic control, are the least likely to emulate their parents and absorb the lessons they teach, while fussy kids are the most likely to do so.

        DNA variants can protect children from bad parenting.

        Both views--that everything is genetic and that parents can transform a child like a lump of clay--are as wrong as wrong can be.

        I think these finding have serious implications for how we look at religion, and how it can or cannot work effectively to shape people's behaviour from the time they are children to adults. Some people -- at least 30 per cent -- are hard-wired to find it difficult to deal with "sin" without feeling guilt, shame, failure and worthlessness.

This is just another example. You'll see in my journal that the MWNN regarding atheists. This supports the atheist understanding of the world. We are born as we are, mostly accidental, or luck of the draw regarding genetics. There is no deity responsible for this.

    As a hobby, I try to build small autonomous robots, and generally speaking most people believe that the human experience is the 100% value or perfect way of interacting with the world. What they forget, and what I like to call 'failure mode' is that we humans are anything but perfect: bad vision, autism, this story's problem, and many other failures. Ever bump into the wall in the dark? There is another failure.

    We are far from perfect, hardly worthy of being called a creation of an all powerful being. Destructive behavior is what we excel at. Brilliant design, eh?

    The answer to such problems is fantastically unimaginable. How do you fix the discards and keep population withing the realms of what the planet can support? China has taken a step in that direction and it has caused unimaginable hardships for their population; selling babies, hiding from the government, fear of things that are only natural.
