institutionalisation - the effects if living in an institutional setting where ppl live for long periods of time eg. hospital or orphanage, in these places there's very little emotional care
Rutter et al (2011) followed a group of 165 romanian orphans over multiple years as part of the english and romanian adoptee study (ERA study), study was to see if good care can make up for poor early experiences in institutions, physical cognitive and emotional development was assessed at ages 4, 6, 11, 15, 22-25, compared to a group of 52 UK children adopted around the same time. Rutter et al found that when the kids first arrived in the UK they were severely undernourished and had delayed intellectual development, mean IQ of control group adopted before 6 months of age was 102 compared to those adopted after 7 months to 2 years which was 86 and 77 for those adopted after 2 years. children adopted after 6 months showed an attachment style called disinhibited attachment (symptoms include attention seeking, clinginess, no difference in social behaviour to family/strangers), children adopted before 6 months rarely showed this attachment style
