What is the difference between a child's capacity to perform a task independently and the potential to perform it with assistance known as?

I am not sure what this question is asking. One of the alternatives gives terms I have never heard of and am not sure exist: heteronomity? What on earth is that? I can only write about autonomy in children's learning. Even in pre-school children it is far better for their cognitive development if they develop autonomy in approaching problems. For instance, faced with a diagram and a pile of lego bricks, it is of little or no use to a child to watch an adult build the car or building.

The adult being on hand to assist is useful, but not to take over. In the same way, an adult might help sort jigsaw pieces into colour groups or even to put possible matches near to each other, but must allow the child the satisfaction of pressing the pieces together. This builds autonomous development. Having the child watch while adult(s) perform tasks puts the child into a state of perceived helplessness so that in the future when faced with a task he will feel incapable and look for another person to solve the problem.
