0-1 months: some reflexes start to come under control
1-4 months: primary circular reactions
4-8 months: secondary circular reactions
9-10 months: object permanence
11-17 months: increased mobility and exploration of environment
18-24 months: transition to Piaget’s Preoperational stage
Lebanese Orphanage Study
- infants 1st year of life: basic physical needs were met, but did not have a lot of social interaction or toys to play w
- at 12 months: delayed physically and intellectually
- second year: simple toys to play with and floor time to play, also had more social interaction with adults
