Rutter et al (2011) study
1. Aim: to test whether good care could make up for poor early experiences in institutions
2. Procedure: Followed 165 Romanian orphans adopted in Britain, testing them at regular intervals to assess physical, cognitive and social development. There was a control group of 52 British children adopted around the same time
3. Findings: At age 11 the mean IQ of the children adopted before the age of 6 months was 102 compared to 86 for those adopted between 6 months- 2 years and 77 for those adopted after 2 years. Children adopted after 6 months showed symptoms of disinhibited attachment
4. Conclusion: There are severe long term effects of institutionalisation but these effects can be avoided if the child is able to form an attachment before 6 months
