Preoperational children fail conservation tasks because of

1

• Preoperational children fail conservation tasks
  because of
• Centration
• A tendency to focus on static states rather than
  transformations

2

• Concrete Operations (7-11)
• Understand conservation tasks
• Can focus on multiple features of an object or
  event
• Can consider transformations, not just static
  states

3

• Limitations of Concrete Operations
• Childrens logical thinking is limited to
  concrete information that can be perceived
  directly
• Cant reason about abstract or hypothetical ideas

4

• Formal Operations (11 on)
• Ability to think abstractly or hypothetically
• What if . . . ?

5

• Can consider all possible outcomes of a situation
  (scientific reasoning)
• Ex pendulum problem

7

• Criticisms of Piagets Theory
• Underestimated role of social environment in
  cognitive development
• Ex Certain experiences (like formal schooling)
  may promote conservation and other abilities

8

• Doesnt explain HOW cognitive development occurs
• Better description than explanation of childrens
  cognitive development

9

• The stage model describes childrens thinking as
  being more consistent than it really is
• Ex Children can solve some conservation
  problems sooner than others

10

• Infants and young children are more cognitively
  advanced than Piaget claimed
• Ex deferred imitation (and thus mental
  representation) is present earlier than Piaget
  thought
