According to Jean Piaget's theory of cognitive development, a key characteristic of the 'Preoperational Stage' is the 'lack of conservation' and 'centration'. If a child believes that the amount of water has increased when poured from two differently shaped glasses into a tall and narrow glass, this thinking of the child illustrates which of the following main cognitive limitations?

Detailed Explanation

According to Jean Piaget's theory of cognitive development, children in the preoperational stage (approximately 2 to 7 years old) exhibit the tendency of centration, meaning they focus on only one aspect of a situation while ignoring others.

Along with this, they lack reversibility (irreversibility), meaning they are unable to mentally reverse a sequence of events back to the starting point. This cognitive constraint prevents them from understanding the principle of conservation (that quantity remains the same despite changes in shape).

• Centration: Focusing on a single perceptual dimension, such as height, while ignoring width.
• Irreversibility: Inability to mentally reverse the pouring process to realize the amount of water remains unchanged.
