- Effects of Privation
- Harlow (1958)
- Monkeys were kept in cages fro m being babies.
- Baby monkeys were kept without their mothers or any form of caregiving.
- Kept in cognitively impoverished conditions.
- Monkeys were often terrified when introduced to other monkeys.
- They often cowered, rocked and bit themselves.
- Sometimes very aggressive and showing no social abilities.
- Curtiss (1977)
- Studied Genie.
- Only been given minimum amounts of food since birth, was strapped to a chair in the day time and was locked in a cage at night.
- Genie had not been spoken to directly all of the her life never learnt how to talk.
- Although Genie learnt to say words, she was never able to learn language and grammar.
- It is difficult to tell if Genie's difficulties after she was found were down to her mistreatment.
- Genie may have had a learning difficulty before, but it is impossible to tell.
- Koluchova (1976)
- Czech twins were kept in a cellar and beaten.
- Before being put in a cellar, they were in care then looked after by their aunt.
- Twins were very fearful and couldn't talk very well upon recovery.
- Twins made a remarkable recovery and grew to be cognitive functioning adults.
- It was concluded that development of left hemisphere (where language centre is) must have developed before the age of 18 months.
- Ways of reversing effects.
- Effects can be modified by support of others.
- Harlow- Effected monkeys paired with younger 'therapist monkeys' who they bonded with. this reduced later effects.
- The effects on the Czech twins were revered by been taken into a loving home.
- They caught up on speech and went on to university.
- The longer privation occurs, the more difficult it is to reverse the effects.
- Loving relationships and high quality care are essential for reversal of effects of privation.
- Effects can be modified by support of others.
- Harlow (1958)
