Introduction

Jean Piaget divided development into four main stages. The ages for each stage are only an estimate—children may reach them at different times based on their heredity and environment. What matters most is the order of the stages, not the exact ages. Each stage includes what was learned before.

CISCE: Class 12

The Four Stages

1. Sensory Motor Period (0–2 Years)

Babies learn by seeing, touching, and moving.
They discover that things still exist when hidden (object permanence).
Each action builds on what they did before.
Example: A baby looks for a toy that was hidden under a cloth.

2. Preoperational Period (2–7 Years)

Children start using words, pictures, and play to express ideas.
They talk about things not present.
Their thinking is centered on their own view.
Example: A child uses a box as a pretend car.

3. Concrete Operation Period (7–12 Years)

Kids begin to think more logically, but only about real objects.
They understand that some things remain the same even if they look different.
They solve puzzles with real items (like blocks or shapes).
Example: A child knows that the shape of moulded clay changes, but the amount stays the same.

4. Formal Operation Period (12 Years & Above)

Young people can think about ideas and possibilities.
They plan ahead and think about “what if” situations.
Their reasoning becomes more advanced.
Example: A teenager imagines different outcomes of a science experiment.

Key Points: Piaget’s Stages of Cognitive Development

Piaget divided development into four stages: sensory-motor, preoperational, concrete operational, and formal operational.
Sensory-motor (0–2 years): Babies learn through senses and actions and develop object permanence.
Preoperational (2–7 years): Children use words, pictures, and play, but think from their own perspective.
Concrete operational (7–12 years): Logical thinking develops for real objects; children understand conservation.
Formal operational (12+ years): Teenagers can think abstractly, plan ahead, and consider “what if” situations.
