Piaget's theory of cognitive development proposes 4 stages of development from birth through adulthood. The stages are: sensorimotor (birth to 2 years), preoperational (2 to 7 years), concrete operational (7 to 11 years), and formal operational (12 to adulthood). Piaget was interested in the underlying reasoning processes that led to children's answers rather than just being right or wrong. He believed that cognitive development occurs through an interaction between innate capacities and environmental experiences as children progress through different stages of thinking.

that intelligence changes as children grow.

was right or wrong. He was more fascinated by the
underlying reasoning process that led to the answer- The
logic.

• Cognitive development occurs through the interaction of
innate capacities and environmental events, and
children pass through a series of stages.

5. Piaget’s theory of cognitive development proposes 4 stages of
development.
• Sensorimotor stage: birth to 2 years
• Preoperational stage: age of 2 to 7 years
• Concrete operational stage: age of 7 to 11 years
• Formal operational stage: age 12 and above

6. The Sensorimotor Stage
Age birth to 2 years-
• During this stage, a child develops object permanence. They
learn about the world around them through senses, reflexes
and motor responses.

7. Pre-operational Stage
Age 2 to 7 years-
• The goal of this stage is symbolic thoughts. A child use
to portray words and ideas.
• Although they begin to use language, they cannot fully
comprehensive adult logic or mentality.
• Children tend to be egocentric thus, they struggle to
understand things from the perspective of others.

8. Concrete operation Stage
Age 7 to 11 years-
• Children starts to think logically about matters.
• They utilize memory, numbers and concept of conservation.
• The goal of this stage is logical thinking. As egocentrism from the
preoperational stage begins to disappear as they become better at
understanding how to others behave.

9. Formal operation Stage
Age 12 to adulthood-
• In this stage, children start using scientific reasoning. They use
abstract thinking to solve problems, look for alternative
solutions to problems.

10. • Piaget’s theory of cognitive development explains how a child
constructs a mental model of the world.
• He argued with the idea that intelligence was a fixed trait.
• He regarded cognitive development as a process which occurs
due to biological maturation and interaction with the
environment.
