Jean Piaget was a Swiss psychologist who published his first paper at age 10 and had his PhD and published over 24 papers by age 21. He developed a theory of cognitive development with four main stages: sensorimotor (birth to age 2) where development is based on senses and developing object permanence; preoperational stage (ages 2 to 7) where imaginary play emerges; concrete operational stage (ages 7 to 11) where thinking becomes more logical and systematic; and formal operations (ages 11 to 16) where abstract and hypothetical thinking develops.

6. Sensorimotor (0-2)
O This stage is characterized by
the absence of language.
O This period is based primarily
on immediate experience through
the senses.
O Object permanence &separation
anxiety develops during this
stage
O Children at this stage are
egocentric

8. 6 stages of development
during sensorimotor

9. Stage 1.
birth
O Behavior is reflexive.

10. Stage 2. 1-4 months
O Learning to control some
aspects of behavior.

11. Stage 3. 4-8 months
O Repeats behavior that are interesting.

12. Stage 4. 8-12 months
O Goal directed behavior.

13. Stage 5. 12-18 months
O Make use of trial and error to achieve
desired end.

14. Stage 6. 18-24 months
O Became a symbol user through language
pretend play.

15. Preoperational stage

16. Preoperational stage (2-7 years
old)
O Children in this stage talks to stuffed
toys, they will tell about imaginary friends
and tell wild stories.
O This is the age adults communicates with
the children.

17. Concrete operational stage

18. Concrete operational (7-11 y.o)
O At this stage the child’s thinking becomes
more logical & systematic.
O Children learns through abstract symbols.
O The child cannot yet apply this logic to
problems that are primarily hypothetical
and verbal.

19. Formal operations

20. Formal operations (11-16y.o)
O The individual comes to think at the level
of adults when they are at their best.
O They can attain logical, rational, abstract
strategies.
O Perspective thought or relativism are
formed.
O The process of reading development as
compared to other stages is significantly
different.
