44 Thieves Study (Bowlby,1944) Aim: To investigate the effects of maternal deprivation on people. Procedure: Bowlby interviewed 44 adolescents who were referred to a child protection program in London because of stealing- i.e. they were thieves. Bowlby selected another group of 44 children to act as ‘controls’. He interviewed the parents from both groups to state whether their children had experienced separation during the critical period and for how long.
Findings: More than half of the juvenile thieves had been separated from their mothers for longer than six months during their first five years. In the control group only two had had such a separation. He also found several of the young thieves (32%) showed affectionless psychopathy (they were not able to care about or feel affection for others). None of the control group were affectionless psychopaths.
Conclusion: Bowlby concluded that the reason for the anti-social behavior and emotional problems in the first group was due to maternal deprivation.
My Case study summary: Christiansens (1970,1974) twin case study is in favor of the genetic aspect of crime. Christiansen examined criminality through a random sample of Danish twins. The results showed a significantly higher scoring of concordance in MZ twins vrs the DZ twin. The MZ twins being at 33% concordance on several levels of criminality against the the DZ twins at 11% of concordance.
Genetics vs. Experience Dean Byrd’s study focused on identical twins, non-identical twins, non-adoptive siblings, and adopted siblings and his results were 52% concordance rate for identical twin which means there are 48% unaccounted to genetics that could be a result of experience. Because identical twins share the same genetics then if one twin is homosexual the other twin should be so it could not be due to genetics homosexuality.
A study of 13,000 New Zealand adults (age 16+) examined sexual orientation as a function of childhood history.30 The study found a 3-fold higher prevalence of childhood abuse for those who subsequently engaged in same sex sexual activity. e
Negatives: -Gene is not specific -unaware of how greatly the genes influences whether or not a person will be homosexual -Similar gene was not found in female homosexuals e

Conclusion With the support of our case studies and other studies, it is genetics and experiences combined that affects the different aspects [ Characteristics, IQ, Perception of the world, Reasoning, Processing, Emotion Response] of a human being M
Counter argument It could solely be genetics that influences an individual It could solely be experience that influences and individual E
