You are watching your two nephews, ages 7 and 4, play with a ball of clay. Your older nephew is getting very frustrated because even though he is using the same ball of clay, his younger brother thinks that when it is a ball there is less of it than when he rolls it out into a longer shape. What Piagetian concept is your younger nephew lacking the ability to perform

reversibility

Explanation:

For Piaget, the cognitive development of the human being begins from the moment of his birth and becomes more efficient and comprehensive as this individual ages and his brain is trained more intensively. For Paiget, this development occurs at stages that are related to the age of the individuals.

Within this theory, Piaget, developed the concept of cognitive reversibility, which is the stage in which a child manages to develop logical thinking, where he is aware of size, quantity, movements and any other situation that is logical.

As we can see in the question above, the youngest nephew has difficulty understanding that if no material is removed from the ball, it will have no less material, even if it is rolled on a long surface. This is a logical concept that the child has a hard time understanding because his cognitive knowledge is still weak in reversibility.
