Individual Differences in Crime Flashcards
Give 2 examples of biological explanations for individual differences in crime.
1) Eysenck
2) Freudian theory
Define ‘extrovert’.
Someone who is outgoing and sociable.
What is the ARAS?
Ascending Reticular Activating System
Why would an extrovert be more likely to commit a crime?
Their ARAS favours inhibition of stimulation and so are often under-aroused by a situation and so they seek more thrilling activities that may lead to criminal behaviour such as theft.
Define ‘neuroticism’.
Someone who is unstable and may overreact.
What is the ANS?
Autonomic Nervous System
Why would someone who is neurotic be more likely to commit a crime?
The ANS is responsible for fight or flight and so someone who reacts strongly to a situation may lash out due to emotional instability and so may commit an impulse crime such as murder.
Define ‘psychoticism’.
Someone who lacks empathy and is manipulative.
Why would someone who is psychotic be more likely to commit a crime?
They lack empathy and also psychotic episodes has shown to involve an increase in testosterone (which is correlated with aggression) and so may lead to violent crimes such as domestic abuse.
Give 2 strengths of Eysenck’s personality theory.
1) Less reductionist due to considering both social and biological factors
2) Rushton supports as found that there is a relationship between high E and P scores and delinquency
Give 2 weaknesses of Eysenck’s personality theory.
1) Low validity due to self-report data on the questionnaire leading to social desirability
2) Rushton didn’t find a relationship between a high N score and delinquency
Define the ‘id’.
The part of personality that seeks immediate gratification for basic urges.
Define the ‘ego’.
The part of personality that aims to satisfy the urges of the id.
Define the ‘superego’.
The part of the personality that controls the satisfaction of urges within the constraints of society and morals.
Why might someone be a criminal, according to Freudian theory?
If someone has a weak superego they may not be able to control the urges of the id in a way that conforms to society and so may lead to going against the law through crimes such as theft and murder.
