Which of the following concept is not introduced by Jean Piaget in his Cognitive Development theory ?

Question

Accepted Answer

Jean Piaget's theory of cognitive development outlines how children construct a mental model of the world. While Piaget discussed symbolic *representation* and symbolic *play* as important aspects of cognitive development, the term "Symbolic" as a specific, defined concept or stage within his core theory (like assimilation, accommodation, or equilibration) is **not** a formal component of his framework. Therefore, Option 3 is the correct answer.

Here's why the other options are incorrect:

*   **Option 1: Assimilation:** Assimilation is a core concept in Piaget's theory. It refers to the process of fitting new information into existing cognitive schemas. Children use assimilation to understand new experiences based on what they already know.

*   **Option 2: Accommodation:** Accommodation is another fundamental concept in Piaget's theory. It involves modifying existing cognitive schemas to incorporate new information that doesn't fit the existing schemas. This is how children adapt their understanding of the world.

*   **Option 4: Equilibration:** Equilibration is the driving force behind cognitive development in Piaget's theory. It's the process of balancing assimilation and accommodation to create a stable understanding of the world. Disequilibrium occurs when existing schemas are inadequate, prompting the child to accommodate and restore balance.

In summary, while Piaget acknowledged the importance of symbolic thought, the term "Symbolic" itself is not a defined process or stage within his theory in the same way that assimilation, accommodation, and equilibration are. Therefore, Option 3 is the correct answer.
