I'm not sure I believe this. My experience with children is that they're almost always smarter than I expected. I think I've found the Wikipedia article about the effect, and the criticisms section [1] matches my bias, in that it suggests the children are confused because they are thinking not just about the material presented to them, but also why they're being asked.

Depends on what you mean by children. Most of these concepts appear as a child ages but I think they get out of the simple ones pretty early. I know before a certain developmental state children will say a taller thin glass holds more then a short wide glass even if you pour them back and forth to show they are equivalent. Once they "get" the concept it is for life but before that it is impossible, logic be dammed.
