Chapter 4: Development

Used to believe children were like small adults, just with less knowledge.

Piaget's theory of cognitive development:
     Stage theory: go through predictable series of changes
     Constructivist theory: child is active thinker
     Sensori-motor stage (0 to 2 y.o.): learn basic cause-effects relations by interacting with environment
          Object permanence: understanding that objects still exist even when we don't see them
     Preoperational stage (2 to 7 y.o.): form mental images, not tied to immediate environment
          Pretend play, animistic thinking
          Egocentrism: do not understand others perceive the world differently
               Theory of mind: understanding that what you know may be different from what people know.
          Centration: consider only one aspect of reality at a time
               Problems of reversibility and conservation
     Concrete operational stage (7 to 11 y.o.): think logically about concrete objects
     Formal operational stage (after 11): think logically about abstract things
