Question

Quizplus · Accepted Answer

The Piagetian concept that the younger nephew is lacking the ability to perform is reversibility. Reversibility refers to the understanding that objects can be changed and then returned to their original state, meaning that the ball of clay can be rolled back into a ball again without losing any clay. The younger nephew's thinking that the amount of clay has changed when it is rolled out shows a lack of understanding of reversibility.
