A

Via socialisation processes

45
Q

Why is personality linked with criminal behaviour via socialisation processes?

Children exposed to teasing at school or child abused at home are more likely to develop it which leads them to behave aggressively.

51
Q

Real world application - Holtzworth-Munroe (1993)

A

Those with hostile attribution bias are over 4 times more likely to die by the age of 50 than adults without.

52
Q

A

When criminals downplay or deny their actions to minimalize the effect or guilt

53
Q

What is minimilisation also known as?

A

Euphemistic labelling

54
Q

What doe studies suggest about minimilisation?

A

Individuals who commit sexual offences are particularly prone to minimilisation.

55

56
Q

What did Lawrence Kohlberg come up with?

A

Stages of moral development

57
Q

Kohlbergs stages

A

He used moral dilemmas to investigate childrens reasoning, there was six stages concerned with justice.

58
Q

What did kohlberg investigate in the reasonings?

Didn’t look for what should be done he looked for the reasoning used to justify the response.

59
Q

A

The sample is biased.

The conditions which are said to cause crime should be present when crime is present, and absent when crime is absent.

63
Q

What are the two components of the differential association theory?

A
  • pro criminal attitudes

- learning criminal attitudes.

64
Q

What are pro criminal attitudes?

A

People socialise in different groups and are exposed to different attitudes. If the pro crime attitudes outweigh the anti crime attitudes, we will become criminals.

65
Q

Learning criminal acts

A

Criminals also learn particular criminal techniques. This may be why crimes “breed” in specific social groups and communities.
This could also account for re-offending as criminals learn more techniques in prison.

66
Q

What crime can differential association theory account for?

A

All crime but not crimes of passion

67
Q

What does differential association suggest?

A

we should be able to mathematically predict how likely it is somebody will commit crime. Frequency, intensity and duration - knowing these means we can predict offending likelihood.

68
Q

What is rationalisation?

A

when criminals provide excuses for their actions. This makes it seem like the criminals are in the right and what they are doing is okay.

69
Q

What does the differential association theory say crime is?

A

A learned behaviour

70
Q

The ID

Representing primitive desires and the need for gratification

71
Q

The role of the ego is to strike a balance between the demands of the id and the constraints imposed by the superego.

73
Q

How is the superego 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.

74
Q

How does the superego cause crime?

A 
Ronald Blackburn (1993)
If the super-ego is deficient or “inadequate” then the ID is given free reign to do as it likes.
75
Q

What does Blackburn believe about the super ego?

A

There are three types

76
Q

What are the three types of superego?

A

Weak superego
Deviant superego
Strong superego

A

The criminal” superego

81
Q
