  12. Infants • After birth neural networks have a growth spurt • Muturation set the course of development • Experiences adjust it • Lack of neural connections explain why we can’t remember those developmental years • 3.5 yrs. old is average memory start time

  13. Sensorimotor to Object permanence • Infants begin cognition (thinking, knowing, remembering) • Begin forming schemas that help assimilate our experiences • Infants go from sensorimotor stage to object permanaence • Things exist even when out of sight
