Piaget's Cognitive Development by: Joerigene Odette C. Neri

2. 4 Stages of Cognitive Development
 Sensorimotor Stage
 Preoperational Stage
 Concrete Operational Stage
 Formal Operational Stage

3. Sensorimotor Stage
Ages: birth to 2
 Sensory perceptions
 Motor activities
 Infant trying to make sense of the
world

4. Sub Stages of the sensorimotor stage
 Reflexes (0-1 month)
 Primary Circular Reactions (1-4 months)
 Secondary Circular Reactions (4-8 months)
 Coordination of Reactions (8-12 months)
 Tertiary Circular Reactions (12-18 months)
 Early Representational Thought (18-24 months)

5. Preoperational Stage
ages:2 to 6
 Language Development
 Egocentrism
 Conservation
 Increase in role playing
 Children will use their
imagination(ex: pretending
an old box is a house)

6. Preoperational Stage
Egocentrism:
- The inability of the child to view
things from another perspective
other than their own
Conservation:
- The awareness that altering a
substance’s appearance does not
change its basic properties

7. Conservation

8. Concrete operational stage
ages: 7 to 11
 Use of logic
 Think logically of concrete events
 Difficulty understanding hypothetical concepts
 Elimination of egocentrism

9. Processes During this stage:
 Seriation
 Transitivity
 Classification
 Decentering
 Reversibilty

10. Formal Operational Stage
Ages: 12 to adulthood
 Think about abstract concepts
 Systematic Planning
 Deductive Reasoning
 Problem Solving
