Piaget's conservation tasks (cute!)

And that right there shows the developmental readiness, or lack thereof, to start learning a great many things.

Not sure I follow what you are saying?

Neither am I half the time! Piaget, and others, studied the transitional stages of human development. The pennies and the liquid tests are designed to to test whether a kid has moved from one stage to another. The earlier stage is very concrete and the older stage is more cognative. Or something.

There are a number of stages......despite being Piageted half to death numerous times and having to regurgitate them for exams and stuff I can never remember them either.

That stuff is fascinating.

Unfortunately, he also taught that the brain stops changing after, I dunno, 12 or so...which we all regurgitated as well.

So wrong!!!!

Still, such is kinda sorta science.

I'm curious.

If the little girl who understood the volume was the same in the glasses said her explanation in front of the little girl who didn't understand, would the second girl quickly comprehend, or would she more likely get confused?

In other words, is this something you have to discover on your own?

That's neat.

My twin nephews... when they were 3 or four used to fall for the broken graham cracker thing. I would break the cookie of one of them (right in front of them) and watch the crying start.

Then I would feel bad... and break the cookie of the other one, so that all was fair again.

I was chatting with wally about this this morning.

He said he can remember an aunt giving his brothers and sisters nickels. By the time she got to him she's run of of them, so gave him a dime.

He was so disappointed because it was smaller.
