Rutter was investigating whether or not the long term effects of institutionalisation could be reversed with loving and nurturing care. This is a longitudinal study incorporating a quasi experiment
165romanian orphans were assessed in variety of ways including their head circumference, height, and cognitive functioning before they arrived for adoption in Britain
All were then assessed again at age 4, 6, 11, 15. There was also a control group of 52 british adopted children to use as a comparison.
Condition 1- Children were adopted before age of 6 months
Condition 2- Children were adopted between age 6 months and 2 years
Condition 3- Children were adopted after 2 years
Findings-
50% of Romanian orphans were found to have an IQ under 80-70. The average is 100
They were also underweight (deprivation dwarfism). The control group had neither of these issues
Findings- 4 years
-At 4 yrs, romanian orphans showed great improvements
-Those adopted before the age of 6 months were now doing aswell as British adopted children
Findings- 11 years
-At 11, the mean IQ scores for those adopted before age of 6 months was 102, compared with those adopted between 6 months and 2 years who had a mean IQ scores of 86, those adopted after 2 years had mean IQ of 77
In terms of attachment, those adopted after the age of 6 months showed signs of a particular attachment style called disinhibited attachment. Symptoms include clingy, attention seeking directed to all adults even strangers
Rutter stated that disinhibited attachment was an adaption to having multiple caregivers during the sensitive period for attachment formation. In poor quality institutions like those in Romania a child might have 50carers none of whom they see enough to form a secure attachment
These findings support the view that there is a sensitive period in the development of attachments- a failure to form an attachment before the age of 6 months appears to have long lasting effects
