Q

What did Holmes and Holmes (1996) investigate?

A

Murder of a young girl and boyfriend and step father was main suspect but no forensics evidence available
Conventional questioning-he denied
Profiler suggests that he has great need for control so ask for his help to solve the crime
Suspect shown photographs of crime scene and believing himself to be in control of investigation, therefore became engrossed in talking about the murder
Showed his familiarity with the crime and gave himself away

Q

What is the top down approach?

A

FBI researchers wanted to improve their profiling techniques and make it more exact. To do this profilers decided to interview 36 convicted serial killers and see if there were any common patterns behind their killings.Using this, they devised a classification system for several serious crimes

Q

What did Lombrosso Do?

A

Lombroso examined the facial and cranial features of hundreds of Italian convicts. Both living and dead. He proposed that the atavistic form was associated with a number or anomalies that where key i dictators of criminality.
Lombroso examined 383 dead criminals and 3839 living ones. He concluded that 40% of criminals had some or all of these features.

Q

What are the weaknesses of Lombrosso theory?

A

Has been found that prisoners’ behaviour has improved significantly following facial surgery. Rates of 42% have been found for those who have had surgery, compared to 70% who didn’t. This undermined the theory, which makes it due to socialisation. People may feel socially accepted therefore crime rates are lower.
Main weakness is that it is racist. can lead to inaccurate results
It is ethnocentric.
Only 40% of the offenders have the features, what about the other 60%?

Q

What did Lagerspetz study?

A

He separated mice into two groups depending on the level of aggression displayed when they were mixed with other mice. The mice that were most aggressive were classified as aggressive (TA) and the other non aggressive were called (TNA). These mice were interbred, by the 19th generation aggressive biting behaviour in TA mice was 52% and in TNA it was only 5%. There was also structural differences.The TA mice has heavier testes and increased serotonin. However the environment still had an influence as both types of mouse can’t be tamed

62
Q

Who is Charles Joseph Whitman?

A

On august 1st 1966 he killed his mother and wife. He then went up to the uni of Texas in Austin and began shooting at people. He fatally shot 14 people and wounded 31 others. During autopsy they discover a pecan sized brain tumour. The relationship between the brain tumour and Whitman’s actions cannot be established with clarity. However, the tumour conceivably could have contributed to his inability to control his emotions and actions

63
Q

What is meant by diminishing responsibility?

A

Can’t be completely held responsible for their crime e.g. manslaughter

64
Q

What is legal precedent?

A

Idea that If a judge had ruled one thing, all other judges should rule that out as well. But an issue with this is that we don’t know if they still have free will of their crimes

65
Q

What is the diathesis stress model?

A

The diathesis stress model states that people need two things to trigger criminality.

66
Q

What are the two things that trigger criminality according to the diathesis stress model?

Genetic vulnerability

A negative psychological experiences

72
Q

What is psychoticism?

A

Lacking empathy, cruel, loner, aggressive and troublesome

73
Q

What does Eysenck suggest?

A

Criminality is possibly inherited as we inherit a nervous system, which predisposes us to have a certain personality type

74
Q

What type of personality has an under active nervous system?

A

Extroverts as they constantly seek excitement

75
Q

What is the role of socialisation?

A

Eysenck also believed that criminals learned through socialisation. He thought that criminals were developmentally immature. They are concerned with immediately gratification like a child
Eysenck also believed that people with high E and N scores had nervous systems that made them more difficult to condition. Because of this they wouldn’t respond to antisocial impulses with anxiety

76
Q

How did Eysenck obtain his data?

A

Assessed 2070 male prisoners who were compared to a control group of 2422 males. prisoners recorded higher E,N and P scores than the control group which accords to the predictions of the theory

77
Q

What were the most important stages in Kohlbergs levels of moral reasoning?

A

It was through punishment

79
Q

What was the second stage in the levels of moral reasoning?

A

Self interest driven

80
Q

What were the problems with Kohlbergs Methods?

A

The dilemma is artificial
The sample is biased
The dilemma are hypothetical
Poor research design

81
Q

What were the problems with Kohlbergs theory?

A

Are there distinct stages of moral development
Does Moral judgement match moral behaviour
Is justice the most fundamental moral principle

82
Q

What are the cognitive explanation of crime?

A

Hostile attribution bias

Minimalisation

83
Q

What is hostile attribution bias?

A

A tendency to interpret other behaviours as having hostile intent

84
Q

What did Dodge and Frame find about hostile attribution bias?

A

That children who had been described as ‘aggressive’ or ‘rejected’ before the study found that they act aggressive. Those who had been described as ‘accepted’ or ‘non-aggressive’ said they was not aggressive

85
Q

How is Hostile Attribution caused?

A

Children exposed to teasing at school or child abuse at home are more likely to develop high levels of hostile attribution bias which leads them to behave aggressively

86
Q

What did Schoenberg and Justye study?

A

They showed 55 violent offenders emotionally ambiguous faces. They compared this to a control group. They found that the violent offenders were more likely to find the image hostile or aggressive compared to the control group

87
Q

What did Holtzwoth-Munroe find about hostile attribution bias?

A

Found that those with HAB are over 4x more likely to die by the age of 50 than adults with low levels of hostile attribution bias

88
Q

What did MacBrayer find about hostile attribution bias?

A

Found that parents with height levels of hostile attribution bias are also much more likely to use harsh discipline and aggressive parenting

89
Q

What is Minimalisation?

A

Where criminals downplay or deny their actions to minimalize the effect of guilt.

90
Q

What can minimalisation also be known as?

A

Euphemistic labelling

91
Q

What did Howard Barabee find about minimalisation?

A

Found among 26 incarcerated racists, 54% denied they had committed an offence at all and a further 49% minimise the harm they had caused to the victim

92
Q

What did Nathan Pollack and Judith Hashmall report about minimalisation?

A

That 35% of a sample of child molesters argues that the crime they had committed was non sexual and 36% stated that the victim had consented

93
Q

Who came up with the differential association theory?

A

Edwin Sutherland (1924- 1939)

94
Q

What did Sutherland say are the 2 components of crime as a learned behaviour?

A

Pro criminal attitudes

Learning criminal acts

95
Q

What are pro criminal attitudes?

A

Where people socialise in different groups are exposed to different attitudes, some are pro crime amd some are anti crime. If the pro crime outweigh the anti crime attitudes then we will become criminal

96
Q

What is Learning criminal acts?

A

Where criminals also learn particular criminal techniques, this may be why crimes breed in specific social groups and communities. It could also account for re offending as criminals learn more techniques in prison

97
Q

What crime does differential association theory not account for?

A

Murder

98
Q

What does Differential association suggest?

A

That we should be able to mathematically predict how likely it is that somebody will commit crime.

99
Q

What are the trireme things Sutherland say we need to measure?

A

Frequency, intensity and duration

100
Q

Why is Sutherland theory applicable to corporate crime?

Another word for corporate crime

102
Q

Criminals do what to avoid the guilt of committing crime?

A

Rationalise

103
Q

What is rationalisation?

A

Where criminals provide excuses for their actions

104
Q

What is the ID?

A

Representing primitive desires and the need for gratification

105
Q

What is the super ego?

A

You get it from your same sex parent, it represents moral and social constraints and works on moral principle

106
Q

What is the Ego?

A

The role of the Ego is to strike a balance between the demands of the ID and the constraints imposed by the super ego

107
Q

How is the super ego determined?

A

In Freudian theory, the structure of the psyche is determined in the first five years of life. The roots of offending are found in this period, especially in the relationship between the developing child and its parents
The Freudian framework implies a number of possible causes for later criminal behaviour

108
Q

What does Ronald Black burn say that the super ego explanation causes crime?

A

Says that if the super ego is deficient or ‘inadequate’ then the ID is given free reign to do as it likes

109
Q

What are the three types of super ego?

A

a weak super ego
A deviant super ego
A strong super ego

110
Q

What is a weak super ego?

A

A moral regulator of behaviour and develops at the end of the phallic stage. It punishes the ego with anxiety when an immoral act is contemplated and with guilt as the act is carried out. It is developed as a result of abnormal relationships with family

111
Q

What is a deviant super ego?

A

A child may develop a super ego in the normal ways but the super ego itself may have deviant values. As a moral regulator it threatens and punishes those behaviours that the parent might find unacceptable

112
Q

What is a strong super ego?

A

An excessively powerful superego would render a person anxious and guilty most of the time since every time they acted on the ID desires. Their super ego would punish them for it. Normally they would express these impulses harmlessly through defence mechanisms. If the super ego prevents this from happening the aggression or sexual desire could build up over time u til it becomes strong enough to overwhelm the ego and turn into crimes such as rape and murder

113
Q

What is Custodial sentencing?

A

The offender is punished by serving time in prison, or in some other place e.g. psychiatric hospital

114
Q

What are the four main reasons for the prison system?

A

Deterrence
Incapacitation
retribution
Rehabilitation

115
Q

What is deterrence?

A

Seeing or experiencing the negative consequences means that the offending behaviour should be avoided in the future

116
Q

What is incapacitation?

A

Sending to prison removes the prisoner from society, putting them out of action

117
Q

What is retribution?

A

Society exact revenge for unacceptable conduct

118
Q

What is rehabilitation?

A

Objective of prison is not purely to punish but to reform through access to development skills

119
Q

What is recidivism?

A

A convicted criminal who reoffends, usually repeatedly

120
Q

What percentage of criminals leaving prison are back into prison?

A

46%

121
Q

What percentage of prisoners that left prison 9 years ago are back in prison now?

A

78%

122
Q

Which country have one on the lowest recidivism rates in the world?

A

Norway

123
Q

What is the token economy program in prisons?

A

Involves being rewarded being set up for desired behaviour, sometimes with punishments to discourage behaviour which is undesirable. Rewards are usually tokens or points which can be traded in for what they actually want

124
Q

What is a primary reinforcers?

A

Things that the prisoner genuinely wants

125
Q

What are secondary reinforcers?

A

Tokens are secondary reinforcers that derive value from association with primary reinforcers

126
Q

What are negative reinforcers ?

A

Doing something to avoid bad circumstances?

127
Q

What is positive punishment?

A

Giving a punishment

128
Q

What is Generalisation?

A

Part of the learning theory principles.
The idea is that desired behaviour once reinforced and established in an institution would be generalised to outside the institution so that appropriate behaviour would be established
We are ‘generalising’ the new positive behaviour to the outside world

129
Q

What is restorative justice?

A

Rehabilitation of offenders through reconciliation with the victims

130
Q

What aims do the restorative justice system aim to provide victims with?

A 
Opportunities to explain the impact of the crime
An acknowledgement of the harm caused 
A chance to ask questions
