1. discontinuity

   • distinct stages
   • transitions are leaps, brief
     • qualitative changes
     • broad: across diverse contexts
     • invariant order

2. characteristics

   • sources of continuity
     • assimilation: incorporate incoming info into concepts understand
     • accommodation: process of improving own understanding in response to new experiences
     • equilibration: balance assimilation and accommodation to stable understanding
       • equilibrium: satisfied
         • new info doesn't fit: disequilibrium
           • dev more sophisticated understanding---advanced equilibrium
   • child is active, investigating

3. stages

   • sensorimotor: to 2
     • all direct experience:
     • brain 3x
     • modify reflexes so adaptive, pleasurable, to interact with objecrs
       • becomes intentional
     • errors

     • symbolic representation in language and mental imagery
       • pretend play
     • egocentrism: own POV
     • centration: focus on single feature (conservation task hard)
   • concrete operational: 7-12
     • can reason logically--concrete
     • dev conservation: can focus on more features
     • can reverse operations
   • formal operational: 12+
     • think deeply about abstract and hypothetical
     • NOT universal

4. Problems

   • mechanisms of growth vague
   • infants more competent than realized
