• real life applications

  One strength is there’s real life applications for the effects of institutionalisation.

  In the past, babies were adopted at a later age, once the biological mum had nursed the baby for some time. However now, babies are adopted earlier. The study has also led to improvements for children being cared for in institutions. Now children have 1 or 2 key workers, instead of many caregivers. So children can form normal attachments and can avoid disinhibited attachment.
• long term experiment- longitudinal

  one strength is the study was longitudinal. rutter studied infants over a long period of time, and re-assessed them 21 years later. so we can see the effects of institutionalisation for not only as soon after they were adopted. this means trends and patterns can be identified, and because the same participants were used throughout, participant variables dont affect the data collected.
