Development: Cognitive

1. Piaget's stages

   • sensorimotor stage
     • P believes that at sensorimotor kids don't have object permanence
     • schema: assimilation and accomodation
   • pre-operational stage
     • P: struggles with conservation (number task and volume task)
     • P: struggles with theory of mind
   • concrete operational stage
     • P: understands that perception is not always right, begin to rely on logical thinking
     • P: understands reversibility of conservation
     • P: still overly use intuitions ex: in rules task
   • formal operational stage
     • P: fully capable of abstract and logical thinking
     • planning, deductive reasoning, hypothesis testing

2. Modern research

   • tests object permanence capitalizing on looking, habituation
   • non-stage development evidence
     • domain-specificity
     • cross-cultural effects
     • reason about abstract concepts
       • physics of objects
       • morality
