Piaget's Cognitive Development Theory
Piaget's theory is a stage theory that describes how children actively construct knowledge through their
interactions with the world. He proposed that children move through four distinct stages of cognitive
development, each characterized by unique ways of thinking and understanding.
Stage 1: Sensorimotor Stage (0-2 years)
Key features: Infants learn primarily through their senses and motor actions.
Object permanence: Understanding that objects continue to exist even when they are out of
sight.
Deferred imitation: The ability to imitate actions that were observed earlier.
Stage 2: Preoperational Stage (2-7 years)
Key features: Children develop symbolic thought and language, but their thinking is still limited.
Egocentrism: The inability to take another person's perspective.
Animism: Attributing human-like qualities to inanimate objects.
Centration: Focusing on one aspect of a situation while ignoring others.
Stage 3: Concrete Operational Stage (7-11 years)
Key features: Children can think logically about concrete objects and events.
Reversibility: The ability to mentally reverse operations.
Conservation: Understanding that the quantity of a substance remains the same even if its
appearance changes.
Classification: The ability to group objects based on common attributes.
Stage 4: Formal Operational Stage (11+ years)
Key features: Adolescents develop abstract and hypothetical thinking.
Propositional logic: The ability to reason about abstract statements and propositions.
Scientific reasoning: The ability to formulate hypotheses and test them systematically.
Key Concepts:
Schema: A mental representation or concept.
