Bolding mine. I find nothing in my posts that demonstrates hostility on my part. Yours though is rampant throughout. Enough said on that subject.
If we are truly now leaving behind the travesty of parsing the meaning of “reality” as relevant, I will be pleased. I’m sure we all forgive you for wasting everyone’s time for over 100 posts.
You have an ongoing objection to the demonstration wherein the adult directs the child to “look at” the glasses of liquid, asserting that this somehow confuses the child and invalidates the experiment. Did you wish the child to be told to sniff the containers, fondle them, taste them, or listen to them? In what manner should the adult have directed the child’s attention otherwise? Of course the child is going to look at the containers, else what is the point? If he watches his toes, or gazes out the window, or falls asleep, his answer will have little relevance to the liquid in the containers. You then apparently realize the foolishness of this argument, stating that it probably wouldn’t have made any difference anyway, probably, maybe, but somebody ought to prove this to you anyhow, probably, maybe, somehow. And you insist this is a good faith argument.
You are now dialing back your generalized claims about “children” and focusing on the 5 to 7 year old range. And you seem to be admitting that something is changing in the child’s understanding of the world at this point. Strange that this is the exact age that LHOD described as capable of understanding conservation for the first time. And the same range at which researchers from Piaget on down have observed this phenomenon. Methinks you are waffling now. Or learning. One may only hope.
I suppose you are correct that no one has bothered to provide exhaustive citations to demonstrate that you do not know what you are talking about. Nevertheless, you do not. Should you wish to inform yourself before continuing, Dogpile is your friend. In case you don’t have a spare browser window available, here are a few cites:
I realize this is merely an appeal to authority, and not even a strictly relevant authority at that. But I think it goes to your statement “I disagree that this is not a controversial matter. Your claims are not simple or uncontroversial”. Einstein may not have settled the matter, but his acceptance seems to carry more weight than your rejection.
The cite above goes on to describe Piaget’s stages. I suggest you take advantage of it. Also,
here is Wiki’s explication. I know, it’s Wiki, but it has lots of links providing further documentation. Call it like a literature search.
And here’s one more:

This one includes a nice graphic representation showing how “most” children move through the stages of development. Sure enough, there is a range, not a magic age. And what do you know, it seems that the overwhelming majority of 5 year olds are “pre-operational” while the majority of 7 and 8 year olds are “concrete operational”. Amazing that this is what LHOD has been telling you all along.
Yes there is some controversy in the realm of childhood development, and not everyone in the field takes their Piaget straight up, without ice or branch water. But the main point of discussion seems to be whether or not individuals move from one stage to another automatically as they biologically mature, or if environmental factors are required. The conclusion so far is that the former applies to the first three stages
but
However, I don’t think that your contrarian claims are sufficient for you to assert ownership of this argument.
In sum, it appears that the current state of relevant scientific thought in the field of cognitive development is that childhood cognition proceeds by stages, that those stages are discrete and describable, that they are present in virtually all children, that virtually all children progress through them in a certain order and within a reasonably narrow age range, and that children at a given stage cannot successfully be taught or instructed to operate at a higher stage except as their developmental level approaches the next level in succession.
Accept it.
