Explanations for offending Flashcards
Eysenck theory background?
Eyeneck was a researcher of personality and intelligence in the mid-20th century.
What is the personality theory?
He proposed behaviour could be represented across 2 dimensions: introversion-extraversion and neuroticism-stability. He later added a third dimension of psychoticism-sociability.
What is the criminal personality?
a person who scores highly on the neurotic, extrovert and psychotic side of the scale.
What did Eysenck say about the basis of personality traits?
Eyesneck argued our personality traits have a biological basis depending on the nervous system we inherit.
Extrovertism basis?
have an underactive nervous system which means they constantly seek excitement, stimulation and are likely to engage in risk-taking and dangerous activities.
Neuroticism basis?
have a high level of reactivity in their sympathetic nervous system. They tend to respond quickly to threats, be jumpy, nervous and anxious. Their behaviour tends to be difficult to predict.
Psychotic basis?
suggested to have had a higher level of testosterone and are unemotional, so are prone to aggression.
What did Eysenck say about the link between personality and offending behaviour?
Personality links to offending behaviour by a socialisation process.
What does the socialisation process do?
The process of socialisation is one in which children are taught to delay the need for instant gratification and become more socially orientated.
Socialisation process and offending behaviour?
Eysenck argued that offending behaviour was developmentally immature in that it is selfish and craves immediate validation.
He also suggested that extraversion and neuroticism makes people difficult to condition, therefore they do not respond to punishment for antisocial impulses. They are more prone to be antisocial which could lead to criminality.
How did Eysenck measure the criminal personality?
Eysenck used the ‘eysenck personality questionnaire’ which locates the position along the E, N and P dimensions.
This allowed him to conduct research into the link between personality and criminality.
Strengths of Eysenck: research support?
Eysenck and Eysenck 1977 compared 2070 prisoner’s EPQ scores with 2422 controls. Prisoners scored higher on all scales than controls, which agrees with the prediction on the theory.
Weaknesses of Eysenck: Farrington?
Farrington 1982 conducted a meta-analysis of relevant studies and reported that offenders scored higher in psychoticism but not in the other categories. There are also inconsistencies of EEGs between extraverts and introverts, and their level of cortical arousal. This casts doubts on the credibility of the theory.
Weaknesses of Eysenck: too simplisitic?
Moffitt 1933 drew a distinction between adolescent offending behaviour and adulthood. She argued personality traits could not predict the length of time of offending behaviour, and the persistence comes from environmental reactions to the behaviour.
Weaknesses of Eysenck: cultural factors?
Bartol and Holanchock 1979 studied Hispanic and African American offenders. All six groups of the participants had a lower extravert score than a control group. This sample is a very different sample to the one Eysenck studied. Questions how far the theory can be generalised.
What is atavistic approach?
=A biological approach to explain offending that attributes criminal activity to the fact that offenders are genetic throwbacks or a primitive species that are ill-suited to conformity to social roles
Lombroso’s theory of atavistic form explained:
Suggests criminals are biologically different.
A lack of evolutionary development means their savage, untamed nature means they cannot adjust to civilised society.
Criminals are distinguishable by facial features.
How does Lombroso’s theory compare in different time period?
At the time, this was a new approach, which suggested the innate tendencies meant the criminals were not to blame. Today, the approach seems naive and speculative.
What are the general characteristics of criminals?
-Sloping narrow brow, strong jaw, high cheekbones, facial asymmetry and extra extremities.
Characteristics of murderers?
bloodshot eyes, curly hair, long ears, cold stares.
Characteristics of sexual offenders?
glinting eyes, swollen fleshy lips.
Characteristics of fraudsters?
thin/reedy lips
Characteristics of thieves?
expressive face and small wandering eyes.
What non-facial features did criminal have according to Lombroso?
It was also argued that ‘born criminals’ had a liking for tattoos, cruel and wicked games and their own language.
What was Lombroso’s research?
Lombroso examined the features of over 4000 of Italian convicts who are dead and alive. He measured head span, neck span, eye colour, weight, the span of their arms, sizes of their hands. He concluded 40% of the crimes were conducted by people with atavistic characteristics.
Strengths of atavistic form?
Lombroso has been hailed as the father of modern criminology as he was one of the first to study crime scientifically. His theory dominated criminal thinking for the late 19th and early 20th centuries. Geared the study towards science and evolution, and away from a moral and religious discussion
Weaknesses of atavistic form: scientific standards?
Lombroso did not use a control group to compare his results, lowering the internal validity of the findings. Scientific standards were not as they are today.
Weaknesses of atavistic form: socially sensitive?
This explanation is socially sensitive; some of the features described by Lombroso are linked to skin colour and other traits are associated with the concept of race, so it has been accused of scientific racism. Many of the atavistic features link to African descent. Therefore contributes to the idea of eugenic policies, arguing that those born with genetic advantages should be allowed to breed but those born with genetic disadvantages should be eliminated to improve the genetic quality of the population.
Weaknesses of atavistic form: Goring?
Goring 1913 carried out the same experiment with 2000 London criminals and could not replicate the results.
Weaknesses of atavistic form: determinism?
This theory is deterministic as it implies that possessing particular innate physical characteristics is likely to lead to crime. It does not take into account the influence of free will and moral/ religious values. This limits its usefulness as it cannot explain individual differences.
Weaknesses of atavistic form: environment?
Some characteristics may not be innate and can be explained by environmental factors, such as poor nutrition in childhood.
What is the neural explanation for offending?
=Explaining offending behaviour in terms of dysfunctions in the brain, including the prefrontal cortex and neurotransmitters. Most of the criminals in studies have been those with antisocial personality disorder (APD).
What is did Raine suggest?
Suggested APD brains have reduced activity in the prefrontal cortex which helps regulate emotions. So they find it difficult to control impulses and do not suffer from guilt.
Raine’s research?
Raine studied 41 violent offenders and compared the activity in their prefrontal cortex to 41 non-criminals (including six schizophrenics) using PET scans. The violent offenders showed significantly less activity in the prefrontal lobe than the other participants suggesting less control over impulsive behaviour.
How does the neural explanation explained adolescent antisocial behaviour?
The prefrontal cortex is not fully developed until the mid twenties, explaining the spike in adolescent antisocial behaviour.
Keysers’ research into mirror neurons?
Recent research suggests APD brains can experience empathy, but it is sporadic.
Keysers 2011 found that criminals’ empathy reaction only activated when asked to empathise. This is because it is controlled by mirror neurons in the brain.
This suggested APD brains have a neural switch, whereas normal brains have the empathy reaction permanently on.
Strengths of the neural explanation?
Use of scientific method and scientific equipment; PET scans.
Kahdel and Free 1989 reviewed evidence of frontal lobe damage and antisocial behaviour. They tended to show impulsive behaviour, emotional instability and an inability to learn from mistakes. This supports the idea that brain damage may be a causal factor in offending behaviour.
Weaknesses of the neural explanation: reductionism?
Explaining crime simply through brain structure is very reductionist. Crime is complex, and the reasons for people turning to crime are many and varied.
Weaknesses of the neural explanation: complex link?
Farrington 2006 studied a group of men who scored high in APD symptoms. These men also had various risk factors from childhood such as being neglected and raised by a convicted parent, and it was suggested that this caused APD and the neural differences were caused by trauma. This shows the link is very complex.
Weaknesses of the neural link: determinism?
The justice system is based on the fact we have free will and that crime is not biologically determined.
What is the genetic explanation for offending?
=Suggests that offenders have inherited a gene/combination of genes that predisposes them to crime.
Christiansen 1997 twin study?
-Christiansen (1977) looked at 3586 twin pairs in Denmark.
A 35% (males) and 22% (females) concordance rate for criminality was found for monozygotic (identical) twins, compared to just 13% (males) and 8% (females) for dizygotic (non-identical) twins.
