Q

Offender profiling- Top-down approach- evaluation-
What are the strengths?

A

Research support for disorganised vs organised.
Canter (2004)- used 100 US murders using small space analysis, identifies the correlation between behaviour concordance of 39 aspects of serial killers.
Suggests many categories which make killers O or D.
Shows key component of of FBI is valid.

Can be adapted to burglary.
Makata (2017)- 85% rise in solved burglary, adds interpersonal (know the victim, take something significant), and opportunistic (generally inexperienced young offenders).
Adds to new categories, so has wider applications.

Q

Offender profiling- Top-down approach- evaluation-
What are the limitations?

A

Evidence base is limited.
FBI profiling= developed with interviews 25 sk and 11 m. 24=O, 12=D.
Canter suggested no scientific basis due to; small sample, small range, no standardised questions, so interviews were not comparable.
Lacks validity and generalisability.

Case study to prove godwins theory.
Dahmer fits into both categories of O and D, (O= type of victim), (D= homosexual)
Contradicts the American approach due to Godwins theory

Q

Offender profiling- bottom-up- evaluation-
What are the strengths?

A

EVIDENCE WHICH SUPPORTS.
Canter and Hretitage (1990)- 66 SA cases, using smallest space analysis, common behaviours include interpersonal language, lack of reaction to the victim. Can identify whether two or more offences were committed by the same person (linkage).
Can help common behaviours amounts t offenders, helping to identify them.

SUPPORTS GEOGRAPHICAL PROCESSING.
Lundrigon +Canter (2001)- 120 murder cases, smallest space analysis revealed consistent behaviour amongst the killers, found crime location reveals a circle around the home base.
This can help us to find a small area in which the offenders can live.

Q

Offender profiling- bottom-up- evaluation-
What is a limitation?

A

GP IS NOT SUFFICIENT ON ITS OWN.
May be reliant on the quantity of data, the recording of the crimes is not always accurate. 75% are not reported.
Critics claim that other factor are important, timing of the offence was also important. And the age and experience (Ainsworth (2001)).
May not be main factor in solving crimes.

A

CONTRADICTORY EVIDENCE.
Goring (1913)- 3000 offenders and 3000 non-offenders were used, there was no evidence criminals had distinct facial features.
Showed people with lower iQs were more i Kelly to be criminals, not based on physical features.
Not accurate.

LACKED CONTROL OVER HIS VARIABLES.
Never compared to a control group, showing his lack of control.
Hay and Forst (2009)- created links to poverty and education rather than with genes.
Didnt look into criminals family history.

800 Finnish offenders

45

Regulates serotonin

47

A

5-10%

49
Q

Biological explanations- genetic- diathesis stress model-
What does this mean?

A

Biological and environmental factors can be paired

50
Q

Biological explanations- neural-
Is there believed to be a neural offenders between offenders and non offenders?

A

Yes

51
Q

Biological explanations- neural- PC- Raine-
What did his analysis fund?

A

There are many Brian imaging studies which show a difference between the activity in the prefrontal cortex between an offender and non-offenders

52
Q

Biological explanations- neural- PC-
What is the prefrontal cortex responsible for?

A

Regulation of emotional behaviour

53
Q

Biological explanations- neural- PC- Raine-
How much less activity was in the prefrontal cortex of an offender?

A

11% reduction in the volume of grey matter in a criminals prefrontal cortex

54
Q

Biological explanations- neural- mirror neurones- Keysers-
What did Keysers study form about people with APD?

A

They can emphasise with film characters in pain when asked to do so, (which is controlled by mirror neurones in the brain)

55
Q

Biological explanations- neural- mirror neurones- Keysers-
What does this research shoe about people with APD?

A

APD patients are not totally without empathy but have a neural switch which they can turn on and off

56
Q

Biological explanations- neural- mirror neurones- Keysers-
What other areas of the brain contribute?

A

The amygdala, and the temporal lobes

57
Q

Biological explanations- genetic- evaluation-
What is a limitation?

A

IT IS ASSUMED THAT TWINS HAVE THE SAME UPBRINGING.
Dz twins are not treated the same as they are not identical, meaning the nurture is different.
The concordance rate between Mz twins could be due to them being treated the same, not sue to their shared genetics.

58
Q

Biological explanations- genetic- evaluation-
What is a strength?

A

RESEARCH SUPPORT.
Mednick- 13,000 adoptees. Found: no conviction (ap and bp) = 13.5%, bp conviction and no ap conviction= 20%, both convictions (ap and bp) = 24.5%

59
Q

Biological explanations- neural- evaluation-
What is a strength?

A

RESEARCH SUPPORT.
Kandel and Freed- reviewed evidence of frontal lobe damage, including prefrontal cortex and antisocial behaviour.
People with this damage show impulsive behaviour.
Supporting brain damage is a factor in offending.

60
Q

Biological explanations- neural- evaluation-
What is a limitation?

A

CONTRADICTING RESEARCH.
Farmington- studied men who score high on psychopathy, these men experienced many other risk factors (such as being raised by convicted parents, or being physically neglects).
Could be seen as early childhood experiences cause APD, showing th interactionist approach, and even neural factors (rauch), such as a reduced activity.
Suggesting complex relationships between offending causes.

61

79
Q

Psychological explanations- Eyesenk- measuring criminal personality-
What did Eyesenk develop?

A

The EPQ (Eyesenk Personality Quiz)

80
Q

Psychological explanations- Eyesenk- evaluation-
What is a strength?

A
  • research support
  • Eyesenk (x2) (1977)- 2070 prisoners, 2422 controls, on the ENP scale prisoner had higher average scores.
  • supports the claim of the EPQ, as prisoner score higher, the theory is more valid.

CA// Farmington (1982)- meta analysis, found criminals had high P and low N and E

81
Q

Psychological explanations- Eyesenk- evaluation-
What are two limitations?

A
  • too reductionist.
  • Moffat (1993)- drew a difference between offending in adolescence and offending in adulthood. Personality is a poor factor got hoe long offending behaviour will go on for.
  • per instance in offending was said to be due to personality and environment (interactionist)
  • more complex
  • culturally biased.
  • Bartol anf Holanchock (1979)- studied Hispanic and African American offenders, found they were less extroverted than a non-offender control group.
  • Eyesenk would have assumed these criminals had a higher E
82
Q

6: morality of conscience (individuals have a personal set of ethical principles)

85
Q

Psychological explanations- cognitive- Kohlberg- moral development-
What did Kohlberg do?

A

Applied mortal reasoning to offending behaviour

86
Q

Psychological explanations- cognitive- Kohlberg- moral development-
What does the higher stage of reasoning mean?

A

The higher the more sophisticated reasoning, which is based on responses to moral dilemmas.

87
Q

Psychological explanations- cognitive- Kohlberg- links with criminality-
Which stage would criminals fall into?

A

More likely to be classified as pre-conventional. Need to avoid punishment and gain rewards. May commit crimes if they can get a way with it or gain something.

88
Q

What is this linked to?

A

The way offenders interpret other peoples behaviour and justify their won actions

89
