Piaget's Theory on cognitive development

• Piarget was a frenchman who we can blame our education systum today on. He regarded a child as a scientist, following a inbuilt path of discovery and thinking.

• He was a child geinious and published his first paper showing hypothertical thinking before he hit the age of 11.

• He carried out most of his experiments into cognative development on his children.

Piarget created a stage theory to explain cognitive development.

Qualitys of a stage theory are:

• developmant follows a fixed order

• behaviorgets better stage by stage

• Pattern is universal (true for evryone)

• People cant go backwards through the stages

•  SENSORI-MOTOR STAGE (lack) 0-2
  • body schema-recognises existance
  • motor co-ordanation- learns to co-ordanate
  • object permanence- learns that objects/people are still their evan if they cant see them
•    PRE-OPERATIONAL STAGE (lack) 2-7
  • animisum- Treat inanimate objects as if they have feelings
  • reversability- being able to put yourself in other peoples shoes
  • (still have) egocentrisum- thinks the whole world revolves around them
•  CONCRETE OPERATIONAL STAGE (develop) 7-11
  • Linguistic humor- Children start understanding and enjoying word games and douddle meanings
  • seriation- Ability to rank
  • conservation- know properties of an object are conserved even if objects appear diffrent
•    FORMAL OPERATIONAL STAGE (develop) 11+
  • hypothetical thinking- can perform thinking tasks and solve logical probems

• some children develop in faster or slower stages an example of this is PIAGET HIMSELF, a child genious

• reserchers argue  that some adults never complete formal operational stage

• sample sizeis tiny as he used his children to develop theorythis makes his findings UNGENRALISABLE
