It is not an assumption. It is a pretty well covered. the fact that the brain, particularly the frontal lobe, is not as fully developed is a major indication. In any case, if you just simply apply common sense, there is really no other conclusion. Just by observing the behavior of younger children compared to the behavior of older children and adults, you can clearly see a major difference in emotional states. Every single day, I have probably at least one or two children in my class who end up crying over something or other. Usually because little Bobby called little Susy a poopy-face. Go into a high school setting, and you have someone crying maybe once a week at most, and usually over something much more severe than simly being called a poopy-face. Go into a business office, you probably won't find anyone crying, unless they receive some really bad news. and most certainly, they won;t be crying over being called a poopy-face.
Neat little experiment, if you can stomach the sadistic nature of it: Go up to a random child, and start calling them a poopy-face. Be like "Nah, nya, nya nyah nay, you're a poopy-face! Hahaha! Poopy face!" Then go up to your next door neighbor or other other adult and try that. See what happens, and the different reactions you will get between young children and adult.
Younger children are treated differently than older children. Parents and teachers are more accepting of greater emotionality in younger children. There are plenty of spoiled older children who throw tantrums and act like little kids. There are also plenty of younger kids who act much more mature than their peers. So how do you know that it's not because of the way they were raised?
I think you asked the wrong question here, because that isn't anywhere near what I said. Read this again:
But it does appear that you are correct that Piaget underestimated child development. This is a point I tend to agree with myself. But I still think there is something to it. I'll explain later, as I have to finish this project I am currently working on.
When it comes to education, certainly teaching children plays an enormous role in making the connections. Biology alone cannot get a person to understand even rudimentary arithmetic skills.....
....*Individuals vary to a great degree as I have said. Some, such as those with social disorders, never fully develop the capability to stop themselves from doing something stupid that will result in negative consequences for themselves, like calling a boss a jerk for instance.
I guess I was not perfectly clear on this point, because I was mainly espousing the role that nature plays, as opposed to nurture.
As I have said in the first quote, nurture is even more important than nature. Without nurture, there is no way of knowing that 1+1=2, or that red berries are probably poisonous. There would be no development of such things as morality.
With pure biological nature, however, it IS possible to form a sort of communication, or some sort of psuedo-language. (The language center in the human brain is nothing short of amazing. It does allow us to develop a sort of language. Example: the movie "
Nell". It is possible to create simple tools, like using a stick to try to poke a pineapple out of the tree to eat it.
After all, kids only spend a fraction of their waking hours at school. Additionally, how do you know that the development of the frontal lobes is not affected by the environment? We know that the environment has a significant effect on the development of the brain. Parts of the brain grow or shrink due to experience. Perhaps development of the frontal lobes is due more to experience than biological maturity.
Heh, well, it is only common sense that the frontal lobe (the entire brain, really) does grow. It grows much like your skeletal framework grows in one sense. When you are first conceived, you are certainly not anything that is recognizable as human. As you become a fetus, your brain hasn't even begun to develop yet. And finally, when you are born, you are merely still pretty much a fetus at full term. You don't just automatically have a fully-developed brain or anything like that.
It also grows differently from your skeletal or muscular systems. While your brain can continue to develop naturally on its own just like your skeletal frame. It develops will develop even quicker and more efficiently along with input from the outside world, unlike your skeletal frame.
So yes, nature certainly is involved in the process. Just how much? Who knows?
