Developmental psychology 1
The important of early environments
Impoverished early environments
Harlow’s Monkeys 1972
Isolation for the rst 3 months: emotional shock
isolation for the res 6 months
isolation for the second 6 month:aggressive and fearful when returned to group cage BUT
quickly recovered
isolation for the rst 12 month: No signs of recovery
E ects of early social deprivation-orphan studies
-Goldfarb(1945)
compared early(<3months) late(>3years) orphan
At age 12:
Early - mean IQ = 95
Late - mean IQ = 72
Dennis(1973): The greater the age of adoption, the lower the eventual IQ attained
Cognitive/Social-emotional
-English/Romanian orphanages
a)111children from Romania who were adopted into English families before the age of 2 yrs
<6months and after <6moths
b) contrast group: 52 adoptees from within England
<6months
At age 4:
Weight, height and head circa get improved
Catch up was greatest for those adopted before 6-months
Romanian adoptees <6months similar English adoptees <6 months
Romanian adoptees after <6months —higher rate of cognitive impairment, autism-
spectrum disorder…
Conclusion
Children who spent the rst period of life in deprived(orphanage) environments
su er lasting cognitive and social/emotional de cits
this deprivation can be overcome by a move to a stimulating (enriched) environment
the early move, the greater the recovery
