Jean Piaget (Cognitive Psychologist)

1. Sensorimotor Stage

   • (Birth - 2 years) an infant understands the world through sensors and movement
     • 'If I can't see it, taste it or touch it then it does not exist'.

2. Preoperational Stage

   • (2-7 years) a child begins to use words and symbols to make sense of the world
     • 'caa' when the cat's box is there or 'caa' when they get the cat food out.

3. Concrete Operational Stage

   • (7-11 years) reason is used to logically make sense of concrete events in the world and to classify objects.
     • 'My trucks' or 'Gracie got an ice cream, why can't I have one?'

4. Formal Operational Stage

   • 11-15 years through adulthood
     • Reasoning becomes more abstract, logical and idealistic. Through trial and error, a child may mix yellow and blue, together to make green.
