Jean Piaget theory of cognitive development has ________ stages.

Correct option is B

The correct answer is (b) 4
Explanation:
Jean Piaget proposed that children progress through four distinct, invariant stages of cognitive development. Each stage represents a qualitative change in how a child thinks, reasons, and perceives the world, ranging from birth to adulthood.
Information Booster:
● Sensory-Motor Stage: From birth to 2 years, where infants learn through senses and actions.
● Pre-operational Stage: From 2 to 7 years, characterized by symbolic thought and egocentrism.
● Concrete Operational Stage: From 7 to 11 years, where logical thinking about concrete events begins.
● Formal Operational Stage: From 12 years and above, involving abstract reasoning and hypothetical thinking.
● Invariants: Piaget argued that all children pass through these stages in the same order, regardless of culture.
Additional Points:
● Option (a): Underrepresentation – Two stages do not capture the complexity of Piaget’s lifelong developmental framework.
● Option (c): Incomplete – Three stages might confuse Piaget with other theorists like Kohlberg or Vygotsky who have different structural counts.
● Option (d): Excessive – Ten stages would imply a much more fragmented view of development than Piaget's broad categorical shifts.

So the correct answer is (b)
