Outline and evaluate the effects of privation on children's development.

Extracts from this document...


´╗┐Outline and evaluate research in to privation. Privation is when a child never forms attachment. A study of privation includes the case study of Genie and Czech twins. Genie was a young girl who was kept in isolation due to her father?s belief that she was mentally retarded, however as she was discovered at age 13, it was too late to test this. Because Genie never formed attachment, her level of speech was very low and even now, has not recovered as upon discovery she was kept in the care of many different psychologists and then was restored to her original home and kept under the care of her mother. ...read more.


Despite this, all children had difficulty forming peer relations. In addition to this study, is a study done by Rutter. Rutter studied 111 Romanian children who all experienced one of the worst cases of institutional care ever recorded however, when the children that came to the UK and were adopted experienced reversal of the effects of privation such developmental dwarfism and insecure attachment if adopted early enough (usually before 6 months). A strength of the Genie and Czech twins study is that they are both case studies. Because case studies involve using many different experimental and non experimental techniques, they collect a lot of detailed research and therefore, increase understanding of privation which can generate even more research and psychological breakthroughs and therefore, both studies are strengthened overall. ...read more.


This means it takes place over a large period of time and therefore, participants drop out. This therefore may lead to sample bias as there may be only a certain type of person in the sample and thus, is not representative. Because of this, the research done by Hodges and Tizzard cannot be generalised to the public and is weakened. Also, Hodges and Tizzard?s as well as Rutter?s study are both natural experiments and thus means there is a lack of control of variables. This means that the adopted children may not have recovered the effects of privation because of adoption, but may be because they had friendly personalities, or were more socialable and thus, were able to form attachment easier. Because of this, the studies lack internal validity as they may not truly be investigating privation and are weakened. ...read more.
