Rutter's ERA(English and Romanian Adoptee) study
see how they have developed and to what extent good care can make up for poor early experiences in institutions.
165 children, all had suffered from the effects of institutionalisation that were adopted in Britain.
Their cognitive, physical and emotional development were tested regularly at the ages of 4,6,11 and 15.
When first adopted all Romanian children were behind British children emotionally, physically and cognitively. They showed signs of mental retardation and were malnourished. The earlier they were adopted the quicker they caught up with UK children. If adopted before 6 months they had an IQ of 102, if between 6 months and 2 years their IQ was 86 and if adopted after 2 years their IQ was 77. Orphans adopted after 6 months were more likely to show attachment disorder and have peer relationship problems , in particular a disinhibited attachment)
