This document discusses Jean Piaget's theories of cognitive development and epistemology. It covers Piaget's four main stages of development: sensory-motor stage, preoperational stage, concrete operations, and formal operations. Each stage is characterized by different cognitive abilities as children's minds develop from birth through adolescence. Play is highlighted as essential to cognitive growth as children assimilate and accommodate new information into their developing understanding of the world.

1. Jean Piaget and his
Theories: Cognitive
Development and
Epistemology

3. Through play,
children assimilate
information
into their schemas,
and accommodate
to their surroundings.
Play Is
Essential
To the development
Of the the human mind.

9. The Stages Of Cognitive
Development:
Sensory Motor “Object
(Birth-2) Permanence”
Preoperational
“Egocentrism”
(2-7)
Concrete “Interiorized
Operations (7-11) Action”
Formal Operations “Abstract
(11-16) Thought”

10. Sensory-Motor Stage (Birth-2)
Six Substages:
1. Random and reflex actions (0-1)
2. Primary circular reactions (1-4)
3. Secondary circular reactions (4-8)
4. Coordination of secondary schemata (8-14)
5. Tertiary circular reactions (12-18)
6. Invention of new means through mental
combinations (18-2yrs)

11. Sensory Motor Substages (1-3)
Random and Reflex
Actions (1st substage):
“Random but Important.”
Primary Circular
Reactions (2nd substage):
“The recognition of
shapes, objects and
faces.”
Secondary Circular
Reactions (3rd substage):
“Imitation.”

12. Sensory Motor Substages (4-6)
Coordination of secondary New Means through new
schemata (4th substage): combinations (6th
substage):
“Intent. Object
Independence. Symbolic “Thought before action.”
Thought.”
Tertiary circular
reactions (5th substage):
“Rapid expansion of
Schema.”

13. Preoperational Stage (2-7)
Preconceptual Stage (ages
two to four)
Preceptual or Intuitive
Thought Period (ages four to
seven)
Key Terms and Concepts:
“Egocentric behavior”
“transductive reasoning”
“syncretic thought”
“juxtaposition reasoning”
“animism”
“artificialism”

14. Preconceptual Stage (2-4)
In the
Preconceptual stage
the child begins to
use language and
mental images, and
attempts to
generalize in
illogical ways.

15. Preceptual/Intuitive
Thought Period (4-7)
In the
Period of Intuitive Thought,
Problem-solving
depends
on instinctive
Thought and
appearances,
not on judgment
Or reasoning.

16. Concrete Operations (7-11)
“… the child now can now
operate in thought on
concrete objects or their
representations.”
--Logic V. Surface
Appearances.

17. Formal Operations (11, or 12 -->)
“Operate on Operations”
“Thinking about thought
rather than about
concrete things.”
-- Hypotheses

18. Epistemology is simply
The development of
Knowledge or logical
Structures over time.
How do we come to
know what we
know?
Development is
continuous and
consistent.
