Piaget's Concept of Cognitive Development

Jean Piaget was a Swiss psychologist who gave us a new way to understand how children’s minds develop. He studied how children think, learn, remember, and solve problems. Piaget explained that children go through different stages as they grow, and at each stage, their way of thinking changes.

• Adaptation: Learning by adjusting to new things around us.
• Assimilation: Fitting new experiences into what is already known.
• Accommodation: Changing what you know to understand something new.
• Piaget said learning is a balance, using both assimilation and accommodation.

The Diagram Shows:

• Sensorymotor (0–2 years) → Starting point: infants learn through senses and actions.
• Preoperational (2–7 years) → Development of symbolic thought and language.
• Concrete Operational (7–11 years) → Emergence of logical thinking.
• Formal Operational (12+ years) → Abstract and hypothetical reasoning.

• A child who sees a leaf shaped like a butterfly and calls it a “butterfly” is using assimilation—using what they know.
• When told not all flying things are birds or butterflies, the child learns to change their idea—this is accommodation.

• Jean Piaget explained that children’s thinking develops in stages as they grow.
• Learning happens through adaptation, using two processes: assimilation (using old ideas) and accommodation (changing ideas).
• The four stages are: Sensorimotor (0–2 years), Preoperational (2–7 years), Concrete Operational (7–11 years), and Formal Operational (12+ years).
• In each stage, children understand and solve problems differently, based on their mental development.
• A child calling a leaf a butterfly shows assimilation, and learning the difference shows accommodation.
