Reversibility (psychology)
In the 1940s the developmental psychologist Jean Piaget assigned the knowledge and conception of physical reversibility an important role in the mental development of the child. As in mathematical set theory, where there is an inverse element for every element of a group , which restores the original state, a child in the concrete operational stage (at the age of 7 to 11 years) develops the ability in his imagination to string together operations and each of them to reverse individual as well as the entire operation. However, this formalistic approach has not caught on in psychology.
