Pre-operational stage is the stage of development proposed by

Correct option is D

The Pre-operational stage is one of the stages of cognitive development proposed by Jean Piaget. This stage occurs roughly between the ages of 2 and 7 years and is characterized by the development of language, symbolic thinking, and imagination, though logical thinking is still developing.
Information Booster:
· The Pre-operational stage is the second stage in Piaget's theory of cognitive development.
· Children in this stage begin to use symbols to represent objects, leading to imaginative play and the development of language.
· Egocentrism is a key feature of this stage, where children have difficulty understanding viewpoints other than their own.
· Conservation (the understanding that quantity remains the same despite changes in shape) is a skill that children in this stage have not yet fully developed.
· This stage prepares the child for the subsequent concrete operational stage, where logical thinking and problem-solving become more apparent.
· Piaget’s work has greatly influenced how educators approach early childhood learning.
Additional Information:
· (a) Bruner – Jerome Bruner proposed the scaffolding theory and stages of learning, but he did not specifically identify the pre-operational stage.
· (b) Skinner – Skinner’s work on behaviorism did not focus on cognitive stages, but on the role of reinforcement in behavior.
· (c) Kohler – Kohler is known for his research on insight learning, which is unrelated to Piaget’s stages of cognitive development.
