Bowlby compared 44 thieves with 44 control patients
Control Ps had experienced early separations, whereas 39% of thieves had experienced early separations
In addition, 86% of the thieves with an affectionless character had experienced frequent separations (12/14 thieves), whereas 17% of the 'non-affectionless' thieves (5 out of 30) had experienced frequent separations
This shows that prolonged early separations of the child from their mother causes affectionless psychopathy, and that this in turn leads to criminal behaviour.
However, there are criticisms with this supporting evidence because only correlational links between early separations and delinquent behaviour were found.
There may be other (extraneous) variables which caused the delinquent behaviour - ex. there may have been other problems at home, which caused the mother to be away from home a lot; which provide a better explanation for the delinquent behaviour
This is a problem because Psychology is a science, and science requires that cause and effect relationships can be established.
Psychodynamic Exp. AO3 - Little evidence for superego
Freud's theory of psychosexual development was only supported by a case study of one boy
Given that none of these individuals had committed crime, it is difficult to extrapolate Freud's ideas concerning the superego to criminal behaviour
This would criticise the deviant superego theory for offending behaviour.
The idea that criminal behaviour reflects an unconscious desire for punishment seems implausible, as most offenders go to great lengths to conceal their crimes which suggests that they want to avoid punishment at all costs.
Psychodynamic Exp. AO3 - Gender bias
Freud proposed that women should develop a weaker superego than men because they don't identify as strongly with their same-sex parent as boys do
Partly because girls do not experience castration anxiety so they are under less pressure to identify with their mothers
As a result of this females should have low morality and are more prone to offending behaviour than males
This suggests that there are fundamental differences between men and women, which is alpha bias and does not match the reality within society
What is the role of the superego according to Blackburn’s theory?
It punishes the ego through guilt and rewards with pride
