Four stages: sensorimotor stage (age 0-2 years) Infants can"t represent objects in thought, instead they can only respond to what they see, hear, and touch what they experience with their senses. Lack an understanding of object permanence (objects continue to exist even when they can"t be seen) If 8 month old baby is reaching for toy, if you cover up the toy, the baby will no longer reach for the toy. Since toy can no longer be seen, assume toy is no longer there. Peek-a-boo: pre operational stage (age 2-7 years)
