Q

How does offender profiling work

A

Methods vary but usually involves scrutiny of crime scene and analysis of evidence in order to generate hypothesis about probable characteristics of the offender

Q

What is the top down approach

A

American approach used by FBI, FBI behavioural scientists gathered in depth interviews with 36 sexually motivated murders including Bundy and Manson. Concluded data could be categorised into organised and disorganised crimes

What are organised offenders

A

Planned crime in advanced, victim is deliberately targeted and they have a type. They maintain high degree of control, little evidence left behind, above average intelligence, skilled professional occupation, socially and sexually competent, married with kids

Q

What is a strength of top down approach

A

Support for organised offenders. Canter tested organised disorganised typology of 100 murders committed by different serial killers. Used analysis called smallest space analysis-statistical technique identifies correlations across different samples of behaviour. Analysis used to assess co-occurrence of 39 serial killing aspects including torture, restraint, conceal body, weapon used and cause of death. Analysis revealed a subset of features that many serial killers matched organised typology. Suggests key component to FBI typology has validity

Q

What is counterpoint of top down approach

A

Many studies show organised disorganised aren’t mutually exclusive. Variety of combinations that occur at any given murder scene. Eg. Godwin argues it’s difficult to class serial killers as one or other type. Killer may have high IQ and sexual competence but commits spontaneous murder. Suggests organised disorganised typology is more of a continuum

Q

What is another strength of top down approach

A

Can be adapted to other crimes like burglary. Meketa reports top down profiling been applied to burglary and seen 85% rise in solved cases. Detection method uses organised disorganised typology but also adds interpersonal (knows victim), opportunistic (inexperienced young offender). Suggests top down profiling has wide application

Q

What is a limitation of top down approach

A

Based on flawed evidence. Developed using interviews with 36 murders in US, 25 who were serial killers. 24 individual classified as organised and 12 disorganised. Canter et al argued sample was poor as it wasn’t random or large sample of varied crimes. No standard set of interview questions either so not comparable. Suggests top down doesn’t have scientific basis

Q

What is aim of investigative psychology

A

Establish patterns of behaviour that are likely to occur across crime scenes to develop a statistical database which then acts as baseline for comparison, specific details of crime can then be matched against to reveal important details about offenders history and family background and determines if series of events committed by 1 person

Q

What is geographical profiling

A

Uses info about location of linked crime scenes to make inferences about home/operation base of offender (crime mapping) and based on principle of spatial consistency (people commit crimes in limited geographical space). Creates hypothese of offenders modus operandi and thinking

Q

Strength of bottom up approach

A

Support for investigative psychology. Canter and Heritage conducted analysis of 66 sexual assaults using smallest space analysis. Several behaviours identified as common in different samples like use of impersonal language and lack of reaction to victim. Can help establish if crime committed by same/different person. Supports basic principle of investigative psychology that people consistent in behaviour

Q

What is counterpoint of bottom up approach

A

Case linkage depends on database and only consists of historical crimes which have been solved. They were solved so maybe they were straightforward to link crimes in first place making circular argument.

Q

What is another strength of bottom up approach

A

Evidence to support geographical profiling. Lundigan and Canter got info from 120 serial killing murder cases using small space analysis it revealed spatial consistency in killers behaviour. Location of each body site created centre of gravity as offender goes different direction each time crime committed. Offenders base can be located in centre of all crime scenes, effect more noticeable for marauders. Supports view that geographical info can be used to identify offenders

Q

What is limitation of bottom up approach

A

Geographical profiling may not be sufficient on its own. Same for investigative psychology, success of geographical profiling reliant on quality of data that police provide. Recording of crime not always accurate, can vary between police forces and 75% crimes not even reported to police. So even if info correct other factors may be more important in building a profile like timing of offence and age/experience of offender. Suggests geographical info alone doesn’t always lead to successful capture of offender

Q

What is central to Eysenck theory and why

A

Personality can be measured, important as enabled him to conduct research relating personality variables to behaviours like criminality

40
Q

What did Eysenck develop and what is it

A

Eysenck personality questionnaire (EPQ), psychological test which locates respondents along E, N, P dimensions to determine personality type

41
Q

What is strength of Eysenck theory

A

Evidence supporting criminal personality. Eysenck and Eysenck compared 2070 prisoners on EPQ with 2422 controls. On measures of extraversion, neuroticism and psychoticism across all age groups prisoners had higher scores than controls. Agrees with predictions of theory that offenders rate higher in all 3 dimensions

42
Q

What is counterpoint to Eysenck theory

A

Farrington et al conducted meta analysis of relevant studies and reported offenders tend to score high on measures of psychoticism but not for extraversion and neuroticism. And inconsistent evidence of differences in EEGs between extraverts and introverts which casts doubt on Eysenck physiological basis of his theory. Means some central assumptions of criminal personality have been challenged

43
Q

What is a limitation of Eysenck theory

A

Idea that all offending behaviour can be explained by personality traits alone is untrue. Moffat drew distinctions between offending behaviour that occurs only in teens (adolescent-limited) and life long (life course persistent). Argued personality traits alone poor predictor of how long offending behaviour would go on for, persistence in offending behaviour result of reciprocal process between individual personality traits and environmental reaction to traits. Suggests offending behaviour due to interaction between personality and environment which is more complex that Eysenck suggested.

44
Q

What is a further limitation of Eysenck theory

A

Cultural factors not accounted for. Criminal personality may vary according to culture. Bartol and Holanchock studied Hispanic/African American offenders in maximum security prison, divide offenders into 6 groups based on offending history and nature of offence, found all 6 groups less extravert than non offenders but Eysenck would expect more extravert. Suggested this was due to different cultural group being investigated. Questions how far criminal personality can be generalised and suggests may be culturally relative concept

45
Q

What did Kohlberg do

A

First researcher to apply concept of moral reasoning to offending behaviour

46
Q

What did Kohlberg propose

A

Peoples decisions and judgements on issues of right and wrong can be summarised in a stage theory of moral reasoning

47
Q

What did Kohlberg base his theory on

A

Peoples responses to a series of moral dilemmas like the Heinz dilemma

48
Q

What have may studies suggested about moral development in crime

A

Offenders show a lower level of moral reasoning than non-offenders, Kohlberg et al using his moral dilemmas found a group of violent youths were at a significantly lower level of moral development than non-violent youths (even after controlling for social background)

49
Q

What is the link between Kohlberg level of moral reasoning and criminality

A

Offenders likely to be classified at pre-conventional level of Kohlberg model (stages 1/2) but non offenders progress to conventional level and beyond

50
Q

What are characteristics of pre-conventional level

A

Need to avoid punishment and gain rewards and is associated with less mature, childlike reasoning, so adults and teens who reason at this level may commit crime if they can get away with it/gain reward like money or respect

51
Q

What is the assumption about pre-conventional level and crime supported by

A

Studies which suggests offenders more egocentric and display poor social skills than non-offender peers.

52
Q

What is characteristics of those who reason at higher levels (conventional level and beyond)

A

Tend to sympathise more with rights of others and exhibit more conventional behaviours like honesty, generosity and non-violence

53
Q

What are cognitive distortions

A

Errors/biases in peoples info processing systems characterised by faulty thinking. We all occasionally show evidence of faulty thinking when explaining our own behaviour but research linked in his to the way which offenders interpret other peoples behaviour and justify their own actions

54
Q

What are 2 examples of cognitive distortions

A

Hostile attribution bias and minimalisation

55
Q

What is hostile attribution bias

A

Tendency to judge ambiguous situations or actions of others as aggressive and/or threatening when in reality it may not be

56
Q

What does evidence suggest about hostile attribution bias

A

Evidence suggests that a propensity for violence is often associated with a tendency to misinterpret the actions of other people (assume others being confrontational when they’re not)

57
Q

What is an example of hostile attribution bias

A

Offenders may misread non-aggressive cues (being looked at) and this may trigger disproportionate violent response

58
Q

What study supports hostile attribution bias

A

Schonenberg and Jusyte presented 55 violent offenders with images of emotionally ambiguous facial expressions when compared with non aggressive matched control group, violent offenders were significantly more likely to perceive images as angry and hostile

59
Q

What is the root of hostile attribution bias

A

Root may be apparent in childhood, Dodge and Frame showed children video of ambiguous provocation (intention neither clearly hostile or accidental), children identified as aggressive and rejected prior to study interpreted situation more hostile than those classed as non aggressive and accepted

60
Q

What is minimalisation

A

An attempt to deny or downplay seriousness of an offence also known as euphemistic label for behaviour

61
Q

What is an example of minimalisation

A

Burglars may describe themselves as doing a job or supporting my family to minimise seriousness of their offence

62
Q

What study supports minimalisation

A

Studies suggested sexual offenders particular prone to minimalisation, Barbaree found among 26 incarcerated rapists, 54% denied they committed the offence and 49% minimised they caused harm to the victim

63
Q

What is a strength of level of moral reasoning

A

Evidence for link between level of moral reasoning and crime. Palmer and Hollin compared moral reasoning in 332 non offenders and 126 convicted offenders using socio moral reflection measure which contains 11 moral dilemma related questions like not taking things that belong to others and keeping promises. Offender group showed less mature moral reasoning than non-offender group. Consistent with Kohlbergs predictions.

64
Q

What is a limitation of level of moral reasoning

A

Depends on the offence. Thornton and Reid found people who committed crimes for financial gain more likely to show pre conventional moral reasoning than those who convicted for impulsive crimes like assault. Pre-conventional moral reasoning tends to be associated with crimes where offender believes they can evade punishment. Suggests Kohlbergs theory may not apply to all crimes.

65
Q

What is a strength of cognitive distortions

A

Has application to therapy. Cognitive behaviour therapy aims to challenge irrational thinking. In case of offending behaviour, offenders encourage to face up to what they’ve done and establish less distorted view of their actions. Studies suggest reduced incidence of denial and minimalisation in therapy highly associated with reduced risk of reoffending. Suggests that the theory of cognitive distortions has practical value

66
Q

What is a limitation of cognitive distortions

A

Limitation is level of cognitive distortions depends on type of offence. Howitt and Sheldon gathered questionnaire responses from sexual offenders. Contrary to what researchers predicted, they found non-contact sexual offenders used more cognitive distortion than contact sexual offenders. Those who had previous history of offending also more likely to use distortions as a justification. Suggests distortions are not used in the same way by all offenders

67
Q

What is differential association theory

A

Proposes that individuals learn values, attitudes, techniques and motives for offending behaviour through association and interaction with different people

68
Q

Example of differential association theory

A

One person might associate with people who have negative attitudes towards crime while another person may be exposed to more positive attitudes

69
Q

What is differential association theory scientific basis

A

Sutherland developed set of scientific principles that could explain all types of offending (eg. Conditions which are said to cause crime should be present when crime is present and should be absent when crime is absent), his theory is designed to discriminate between individuals who become offenders and those who don’t, regardless of social class or ethnic background

70
Q

How may offending behaviour be acquired

A

Through process of learning, learning occurs through interactions with signify others who child values and spends time with like friends and family

71
Q

What does differential association theory suggest about offending as a learnt behaviour

A

Possible to mathematically predict his likely it is an individual will commit an offence, to do it we need to know frequency, intensity and duration of exposure to deviant and non deviant norms and values

72
Q

What to factors does offending arise from according to differential association theory

A

Learned attitudes towards offending and learning of specific offending acts

73
Q

What are learning attitudes in differential association theory

A

When a person socialised into group they will be exposed to values and attitudes towards the law, some of the values will be pro-crime some anti crime. Sutherland argues if number of pro criminal attitudes person exposed to outweighs anti criminal attitudes they will offend. Learning process is same whether person is learning offending or conformity to the law

74
Q

What are learning techniques in differential association theory

A

Being exposed to pro crime attitudes, the would be offender can learn certain techniques to commit offences. Including how to break into a house through locked window or disable car stereo before stealing it

75
Q

What did Sutherland find about socialisation in prison

A

Can account for why so many convicts from prison reoffend. Reasonable to assume that whilst inside prison inmates learn specific techniques of offending from other, more experienced offenders that they put into practice on their release, learning may occur through observation and imitation or direct tuition from offending perrs

76
Q

What is a strength of differential association theory

A

At the time it was published it changed focus of offending explanations. Sutherland successful in moving emphasis away from biological account like Lombroso atavistic form to the fact deviant social circumstances and environments may be more to blame for offending than deviant people. This approach more desirable as offers realistic solution to problems of offending instead of eugenics or punishment

77
Q

What is a counterpoint to differential association theory

A

Theory runs risk of stereotyping people who come from impoverished, crime ridden backgrounds as unavoidably offenders. The theory suggests exposure to pro crime values is sufficient to produce offending in whose who are exposed to it. This ignores fact that people may choose not to offend despite influences

78
Q

What is another strength of differential association theory

A

Can account for offending in all sectors of society. Sutherland recognised some types of offence, like burglary, maybe clustered within inner city working class communities, and offences may be clustered in more affluent groups in society. Sutherland interested in corporate offences and may be a feature of middle class social groups who share deviant norms and values. This shows that it’s not just lower class who commit offences and principles of differential association can be used to explain all offences

79
Q

What is a limitation of differential association theory

A

Difficult to test predictions of differential association. Sutherland aimed to provide scientific, mathematical framework to predict future offending behaviour so predictions must be testable. But many concepts can’t be operationalised. Eg. Hard to see how number of pro crime attitudes could be measured. Also theory build on assumptions that crime occurs when pro crime attitudes outweighs anti crime. But can’t measure these so don’t know if offending career has been triggered. Means theory doesn’t have scientific credibility

80
Q

What is the tripartite structure to personality

A

Superego, Id and ego

81
Q

When is superego former and what is it

A

End of phallic stage of development when children resolve Oedipus complex, superego works on morality principle and exerts its influence by punishing ego through guilt for wrongdoing, and rewarding it with pride for good moral behaviour

82
Q

What did Blackburn argue about psychodynamic explanations of offending

A

If Superego is deficient or inadequate then offending behaviour is inevitable as Id given free rein and not properly controlled

83
Q

What 3 types of inadequate superegos have been proposed

A

The weak superego, the deviant superego, the over-harsh superego

84
Q

What is the weak superego

A

If same-gender parent is absent during phallic stage, child can’t internalise a fully formed superego as no opportunity for identification, make immoral/offending behaviour more likely

85
Q

What is deviant superego

A

Superego that a child internalises has immoral or deviant values this would lead to offending behaviour. Eg. Boy who is raised by a criminal father is not likely to associate guilt with wrongdoing

86
Q

What is the over harsh superego

A

Healthy superego based on identification with a parent who has firm rules but forgives transgressions. Contrast an excessively punitive or overly harsh parenting style leads to over harsh superego who is crippled by guilt and anxiety, may unconsciously drive person to perform criminal acts to satisfy superego need for punishment

87
Q

What is the role of emotions on inadequate superego

A

Inadequate superegos aloe primitive, emotional demands to become upmost in guiding moral behaviour

88
Q

How is role of emotions key feature of inadequate superego in psychodynamic approach

A

Approach deals with emotional life of the individual, eg. Acknowledges role of anxiety and guilt in development is of offending behaviour, also means lack of guilt is relevant to understanding offending behaviour as in case of maternal deprivation theory

89
Q

What did Bowlby argue about maternal deprivation

A

Ability to form meaningful relationships in adulthood depended on child forming a warm, continuous relationship with a mother figure. Failure to establish this in first few years of life means child likely to experience damaging and irreversible consequences in later life

90
Q

What is a consequence of maternal deprivation

A

Affectionless psychopathy- characterised by lack of guilt, empathy and feelings for others, such maternally deprived individuals are likely to engage in acts of delinquency and can’t develop close relationships with others

91
Q

How did Bowlby support his claims about maternal deprivation and affectionless psychology using 44 juvenile thieves

A

Found through interviews with thieves and their families that 14 showed personality and behavioural characteristics classed with affectionless psychopathy and of the 14, 12 experienced prolonged separation from their mothers in infancy. Non offender group only 2 experienced prolonged separation. Bowlby concluded effects of maternal deprivation has caused effectionless and delinquent behaviour in juvenile thieves

92
Q

What is a strength of psychodynamic explanations of offending

A

Research support for link between offending and superego. Goreta conducted Freudian style analysis of 10 offenders referred for psychiatric treatment. In all those assessed disturbances in superego formation were diagnosed, each offender experienced unconscious feeling of guilt and need for self punishment. Goreta explained this as consequence of over harsh superego, need to punish manifesting itself as desire to offend. This evidence supports role of psychic conflicts and over harsh superego as basis of offending

93
Q

What is a counterpoint of psychodynamic explanations of offending

A

Generally central principles of inadequate superego theory not supported. If this theory correct we would expect harsh, punitive parents to raise children who always experience guilt and anxiety. Evidence suggests opposite is true, parents who rely on harsh forms of discipline raise rebellious children who rarely express guilt. Calls into question relationship between strong, punitive internal parent and excessive feelings of guilt within the child

94
Q

What is a limitation of psychodynamic explanations of offending

A

It is gender biased. Assumption with Freudian theory is girls develop weaker superego than boys as identification with same gender parent isn’t as strong as girls don’t experience intense emotion associated with castration anxiety, so under less pressure to identify with their mother. Implication is women should be more prone to offending than men but imprisonment rates show opposite. When children had to resist temptation Hoffman found no evidence of gender differences. Suggests alpha bias in Freud’s theory so may not appropriately explain an offending behaviour

95
Q

What is another limitation of psychodynamic explanations of offending

A

Bowlby theory only based on association between maternal deprivation and offending. Lewis analysed data drawn from interviews with 500young people and found maternal deprivation poor predictor of future offending. Even if their is a link their is not necessarily a causal cause, countless other reasons for this link like maternal deprivation may be due to growing up in poverty explains later offending. Suggests maternal deprivation may be one reason for later offending but not only reason
