Q

Offender profiling

A

The aim of profiling is to create an idea of the offenders likely characteristics. This helps the police to focus their resources on more likely suspects, and can create new leads within an investigation

Q

The American ‘top-down’ approach

A

The FBI began by interviewing 36 convicted killers and sex murderers to gain an insight into their thinking and behaviour. They were classified into groups of organised and disorganised. These are used to compare info from new crime scenes to make judgements based on past. However it is based on self-report interviews and a restricted sample, a,so lacks validity and cannot be generalised to wider world

Q

The British ‘bottom-up’ approach

A

Applies psychological research and theories to criminal investigations. Geographical profiling which sees the crime scene as a source of into, the behaviour of the offender would reveal information about their everyday life and characteristics. Also analysed behaviour of convicted offenders

Q

Four main stages when building a profile (FBI)

A

Assimilating data- collecting all info available at scene and from victim.
Classifying the crime- identifying type of crime committed.
Reconstructing- involves behaviour of both offender and victim
Profiling- making judgements about possible physical characteristics and lifestyle of offender

Q

Faults of offender profiling

A

Can only be used for a limited number of crimes such as murders or rapes. Can be used to identify stalkers or arsonists but cannot identify crimes for material gain like theft. Profiling cannot identify a specific person, more so a type of person. Holmes (1989) found profiling to causes arrest in 17% of 88 arrests in 192 cases (ineffective).

Q

Lombroso (1835-1909): physical characteristics and crime

A

Studied for common physical characteristics among criminals. Concluded that they were more likely to have atavistic (primitive) features, strong jaw and heavy brow. Other features included dropping eyelids, large ears, lobeless ears, high defined cheekbones, flat nose. Lombroso believed that criminal behaviour came from primitive instincts which survived evolutionary process - genetic ‘throwback’.

Q

Pros and Cons of Lombroso

A

Highlighted the role of biology in criminology. Considered the interaction between biological, psychological and social factors.
Didn’t use a non-criminal control group to test if features were unique to criminals. Lots of samples had psychological disorders or chromosomal abnormalities which may have been a factor in their crime

Q

Genetic factors of criminality

A

Some adoption studies have shown higher concordance rates of criminal activity between adopted children and their biological parents, there is a genetic link but there are also other factors. Some psychologists believe that aggression can lead to offending behaviour, studies have shown a link between genes and aggression. A higher percentage of prisoners compared to the world showed an extra Y chromosome XYY which adds more testosterone and violence. However further studies suggested that those with such an abnormality are more likely to be hyperactive, impulsive and lower IQ which can explain criminality

Q

Raine et al (1997)

A

Investigated a link between brain dysfunction and criminality. Used PET scans to create 3D images of the functional processes happening in the brains of 41 murderers (pleading not guilty by insanity) and 41 control pptts. The murderers showed reduced glucose metabolism in the prefrontal cortex and corpus callosum and asymmetrical activity in the two hemispheres. So some processes were dysfunctional which supported the link. The researcher used a control group matched on age and sex. But researchers could not randomly allocate pptts to control or killers groups so need to be cautious when drawing conclusions about casual relationships

Q

Strengths of the Biological explanation for criminal behaviour

A

A number of studies have provided support to suggest there is some contribution from biological factors. The biological theories can often be tested scientifically, making them more reliable.

Q

Weaknesses of the Biological explanation for criminal behaviour

A

No study has shown a 100% concordance rate between MZ twins or parents and children so there must be other factors. Concordance rates for criminality may not be directly due to genetics, could be a result of inherited emotional instability or mental illness which could indirectly result in offending behaviour. Biological explanations can be too reductionist and deterministic

Q

Eysenck’s criminal behaviour as personality types

A

Neuroticism stability, Extraversion introversion, psychoticism.
Suggested that individuals have genetic predispositions to a particular personality type, but environmental factors play a role to. Psychoticism was a good predictor of criminal behaviour, Extraversion for young people, neuroticism for older people. Combined biological, social and psychological approaches. However it was developed from studies which involved self-report measures so could lack reliability

Q

Psychoticism

A

This scale shows how disposed an individual is to psychotic breakdown. Those who score highly tend to be aggressive, hostile and uncaring

21
Q

Cognitive approach to criminal behaviour

A

Criminal thinking patterns, cognitive distortions and different levels of moral reasoning are all import factors. A longitudinal study examined 255 male offenders from a variety of different backgrounds. First group had offenders at hospital as they are not guilty due to mental illness. The second is offenders from normal prison population, each went through a series of interviews. 52 thinking patterns were common across all pptts such as automatic thinking errors ( lack of trust, empathy, manipulativeness) and crime-related patterns (fear and need for power). Shows that criminals share common thinking patterns and errors. Since there was no control group results are less valid. Only males were studies (gender bias), hard to replicate (longitudinal). Has ecological validity

22
Q

Cognitive disorders

A

Irrational thought patterns which give people a distorted view of reality, affect how they behave. Includes being self-centred, minimising the seriousness of offending behaviour, blaming problems on others, hostile attribution bias.

23
Q

Level of Moral Reasoning

A

Kohlberg thought that moral reasoning progresses in stages, moral understanding increases as you grow older as you take more of the social world into account. Used a series of moral dilemma stories and sampled 72 boys ages 10,13 and 16 and came up with three levels of moral reasoning: preconventional, conventional, postconventional. Serious offenders have a moral outlook that differs from the law-abiding majority. Gender and culture bias (US boys) making it androcentric focusing on male orientated ideas of justice without moral approaches of women

24
Q

Pre conventional Reasoning

A

An action is morally wrong if the person who commits it is punished as a result (most common in children). The right behaviour is the one that is in your own best interest.

25
Q

Conventional Reasoning

A

The right behaviour is the ones that makes other people think positively about you. It is important to obey laws and follow social conventions because they help society to function properly

26
Q

Post Conventional Reasoning

A

The right course of action is the one that promotes the greatest good for the greatest number of people. Actions are driven by abstract, universal principles of right and wrong, which don’t depend on the situation

27
Q

Psychodynamic approach to criminality

A

Freud claimed that the only way to really understand how people behave is to look at their past, proposed offending behaviour is linked to early childhood experiences. He created theories like an inadequate superego and defence mechanisms

28
Q

Inadequate superego

A

Criminality could be an abnormal development of the id ego and superego, id produces instinctive drive towards criminality and superego keeps it in line. A weak superego- fewer inhibitions towards conducting antisocial behaviour, fully responsive to id for pleasure. A deviant superego- if the same sex parent is immoral, superego may be less responsive to crime than someone without a criminal parent. A strong (over-harsh) superego- if a person thinks about crime a strong superego may make them feel guilty and feel like they need punishment and so engage in crime to get caught

29
Q

Defence Mechanisms

A

Displacement, Repression and Denial. Displaced aggression in offenders might explain their antisocial behaviour. If offenders cannot control their aggression, this aggression may then ‘spill out’ of their unconscious resulting in violent and offending behaviour. Most people can repress and deny their urges and keep them at bay but psychodynamic approach suggests a triggering incident or stimulus may release these feelings resulting in offending behaviour.

30
Q

Weaknesses of psychodynamic approach to crime

A

It is difficult to scientifically test the theories because it considers unconscious processes making it unreliable and lacking in validity. Lots of data to criminology is from case studies and is qualitative and so it’s hard to use it to state laws that can be generalised

31
Q

Differential Association Theory

A

Criminal behaviour is learnt and it comes from interacting and communicating with other people, most likely learnt from amongst small groups of people (most influential). Involves learning of the techniques but also motivation and attitude towards crime. The law tells what’s right or wrong, the criminal then decides what’s favourable and unfavourable. Repeated exposure to criminal behaviour is more likely to result in someone committing a crime especially if the witnessed crime results favourably. The frequency duration and intensity of interactions with criminals and those learning is an important factor. Suggests anyone can be a criminal. Explains why people often reoffend as they spend time with other criminals in prison.

32
Q

Strengths of the differential association theory

A

Accounts for all types of people, not just juveniles or lower class people who are often described in theories of crime. Theory also supported by Short(1955) who studied 176 school children using a questionnaire, found a positive correlation between self reported delinquent behaviour and association with delinquents or criminals

33
Q

Weaknesses of the differential association theory

A

Not everyone is influenced by the people around them, doesn’t consider individual differences. Problems in defining crime make this theory hard to test as it is hard to objectively measure attitudes towards the law and crime

34
Q

Aims of custodial sentencing

A

Retribution (punishment)- the offender should rightfully ‘pay’ for their crime, and deserves the punishment.
Rehabilitation- giving a chance to get their life back on track
Incapacitation- protecting the public by removing the offender
Denunciation- showing public that offenders actions are wrong
Deterrence- stop future crimes by showing punishment

35
Q

Psychological effects of imprisonment

A

Mental Health Problems, Institutionalism, Reinforces criminal behaviour, Labelling

36
Q

Prison leading to Mental Health problems

A

Prisoners may more easily acquire depression and attempt suicide. Zimbardo’s study showed high levels of emotional distress among prisoners. Tests found an association between suicide and guilt over the offence. Prisoners may have had psychological problems before which caused their offence so it’s hard to determine a cause and effect

37
Q

Institutionalism

A

Being kept in a prison often strips offender of their autonomy. Studies such as Zimbardo’s have shown that prisoners are quick to conform to given roles and become dependent on others within their environment

38
Q

Imprisonment reinforcing criminal behaviour

A

Putting people who’ve committed crimes all together in one place can become a breeding ground for crime. Prisons can reinforce the criminal lifestyle and support criminal behaviour as a result of inmates teaching each other about crime

39
Q

Labelling

A

When offenders are released from prison, they still hold the stigma of having been ‘inside’. They may find it difficult to get a job or maintain their social network, which in turn increases the likelihood of reoffending

40
Q

Negatives of custodial sentencing

A

Argued that it only exists to the please the public as a sign of ‘justice’ being served and if it really was a deterrent there would be no crime today. Putting resources into prevention may be more efficient as it removes consequences of imprisonment. Argued that it doesn’t suit all, maybe community service would be better for small crimes, allowing low-risk offenders to keep social contacts and jobs which is important when they finish their sentence

41
Q

Recidivism

A

Means repeating an undesirable behaviour after you’ve been punished for it. Factors that influence this in prison involve:
Time spent in prison, supervision after conditional release, disciplinary reports, education level, seriousness of crime committed, prisoner ethnicity, individual experiences in prison

42
Q

Token Economy Programme

A

A form of behaviour modification based on operant conditioning through consequences, rewards which reinforce behaviour and punishments which discourage it. Reward subjects with ‘tokens’ for meeting behaviour ‘goals’ and then tokens are saved up and used to buy rewards.

43
Q

What things need to be established to set up a token economy

A

The behaviour that is desired from the inmates must be clearly defined
A variety of rewards must be given to encourage participation
The reasons for token allocation must be clear
What a token is worth must be clearly established
The rate of earning tokens must also be established

44
Q

Strengths of the token economy

A

Milan and McKee (1976) studied using token economy in a cellblock of an American male prison. Compared inmates behaviour in several conditions involving normal prison methods, a system of behaviour monitoring and encouragement without using tokens, and a full token economy. They found that inmates performance for monitored behaviours was best when a token economy was in effect.

45
Q

Weaknesses of a token economy

A

Positives effects of token economy may not stay in place once people leave the programme. A test studied the effect of a token economy on ‘delinquent’ youths. They found that rates of criminality were reduced during the programme, but returned to the same rate after the programme. Token economies can be unethical if a reward is something that is a right rather than a privilege (like food)

46
Q

Anger Management

A

A therapeutic programme which assumes violent behaviour is caused by anger and frustration, so if they learn to control anger, violence is reduced. Uses cognitive behavioural techniques to improve individual’s self-awareness and control to reduce violence and make a difference after release. Pptts are encouraged to monitor their own behaviour patterns and emotions so that they become increasingly aware of their own emotional changes

47
Q

Ireland (2000)- effectiveness of anger management

A

Aggression levels of 50 inmates in a young offenders’ institution were measured two weeks before a anger management programme was started. A record of each prisoners aggressive behaviour over one week was kept and they completed a questionnaire and had a cognitive-style interview. Measurements were repeated after 8 week programme. There was improvement in 92% of pptts and 8% were worse after. It was useful in treated aggression short term. It must have been difficult to control other variables that may have had an effect on inmates’ anger, such as news from friends and family. Also all pptts were young offenders to results cannot be generalised

48
Q

Restorative justice

A

Focuses on criminals making amends directly to the people they’ve harmed, helps them take responsibility for actions and be aware of real damage caused. Can be used to various offences, the victim must volunteer to use the approach and offender must have admitted responsibility. May involve face to face communication. Can involve offenders working to undo damage caused

49
Q

Advantages and Disadvantages of restorative justice

A

It reduced post-traumatic stress in victims, and they were less likely to want violent revenge. Both criminals and victims were more satisfied with this approach than with traditional justice solutions. It decreased the costs involved. One main problem is that people are reluctant to use it due to possibly a lack of info
