Jean Piaget Developmental Psychologist

  • Proposed STAGE THEORY of cognitive development.

30
Cognitive Development (CD)
  • Schemas
  • Assimilation
  • Incorporation of new experiences into existing
    schemas
  • Accommodation
  • Changing existing schemas based on new
    experiences

31
Piagets Theory of CD
  • Sensorimotor Stage Birth-2 yrs.
  • Preoperational Stage 2-7 yrs.
  • Concrete Operational Stage 7-12 yrs.
  • Formal Operational Stage 12 yrs. plus

32
Piagets Theory of CD
  • Sensorimotor Stage
  • Lack Object Permanence

33
Piagets Theory of CD
  • Preoperational Stage
  • Lack of Conservation

34
Piagets Theory of CD
  • Preoperational Stage
  • Egocentrism

35
Piagets Theory of CD
  • Preoperational Stage
  • Theory of Mind

36
Piagets Theory of CD
  • Concrete Operational Stage
  • Conservation
  • Mathematical
  • Transformations

37
Piagets Theory of CD
  • Formal Operational Stage
  • Abstract Logic
  • If, Then Logic
  • Ready for
  • Moral Reasoning

38
Piagets Theory Today
  • May undermine childrens abilities
  • Development is probably more continuous

39
CD in adulthood
  • Crystallized Intelligence
  • ones accumulated knowledge and verbal skills gt
    increases with age
  • Fluid Intelligence
  • ones ability to reason speedily and abstractly gt
    decreases during late adulthood
