Q

What is the top down offender profiling

A

Uses pre-existing templates of different types of offender (organised/disorganised). Information from the crime is used to fit the offender into one of the pre-existing categories.

Q

Describe the process of creating the top down offender profile

A

Crime Context (Profiling inputs) – gather victim information, background crime context.
Type of murder (Decision Process Model) – consider type of murder (mass, serial, killing spree), time, location factors
Crime Assessment – use previous information to establish whether offender is organised or disorganised (crime scene characteristics)
Criminal Profile – use organised or disorganised plus previous information to put together a profile (likely personality and behaviour)
Report Writing – report presented to police
Apprehension – review profile again once suspect has been apprehended, review accuracy to improve.

Q

Bottom up offender profiling investigative profiling (AO1)

A

Data-driven approach. Makes use of statistical data on similar crimes that have been committed, in order to make predictions about the characteristics of an offender.

Interpersonal Coherence:- behaviour consistent across crimes and situations.

Forensic Awareness: - Behaviour does change as they develop knowledge of forensics. Adapt and improve. Suggestions preconvictions if offender shows evidence of hiding forensics.

Smallest Space Analysis:- Statistical analysis of DATA!
For stranger murders in UK; looked at 48 crime scenes; interviewed murderers in each case; CORRELATED type of offender to data gathered at the crime scene. Multiple correlations.
3 types of offender: instrumental opportunistic; instrumental cognitive; expressive impulsive;

Q

Bottom up offender profiling geographical profiling (AO1)

A

Geographical profiling: Based on the principle of spatial consistency.

Routine activity theory- offenders will restrict their work to areas they are familiar with (schemas)
Circle theory – A circle drawn to encompass all the crimes in a series is likely to contain the offender’s base
Marauders: Offenders who commit crimes in close proximity to their home base
Commuters: Offenders who travel a distance away from their usual residence but commit crimes with a defined space

Improvements through CGT (Computerised Geographical Targeting) – 3D mapping, terrain, time and mode of transport.

Q

Biological explanations: historical approach (Atavistic = Lombroso) AO1
Just explain

A

Offenders are primitive = ‘atavistic’
Genetic throwbacks: Lower evolutionary development
Savage and untamed nature means they cannot fit in with society and would inevitably turn to crime. Lower moral standards-engage in offending to satisfy own immediate needs.

Q

Biological explanations: historical approach (Atavistic = Lombroso) AO1
Study

A

Atavistic traits:- large sloping brow, dark skin, hairiness, stigmata, large jaw, large ears, insensitivity to pain. Sex offenders = thick lips and protruding ears; murderers = bloodshot eyes, curly hair.
Sample = 383 Italian criminal skull and 4500 live criminals.
21% had one atavistic trait; 45% had 5 or more atavistic traits

Q

Genetics (AO1)
Candidate gene

A

Candidate gene: Any gene suspected of being implicated in a particular trait

MAOA-L mutation ‘Warrior Gene’
Low serotonin in the PFC– linked to impulsivity
High dopamine – linked to rewarding aggression & increased perception of threats in the amygdala

CDH-13:
13 x more likely to have history of violence.
High dopamine – linked to rewarding aggression & increased perception of threats in the amygdala

Q

Genetics (AO1)
Epigenetics

A

Epigenetics: child environmental factors, e.g. child abuse turn off the MAOA and switch on the CDH-13 genes. These develop more dopamine and reduce serotonin, it makes the person more impulsive and aggressive, they then are more likely to have more negative life events, e.g. physical abuse (e.g. fights).

Q

Neurochemistry AO1

A

Dopamine: High levels in limbic system (reward neurotransmitter, excitatory). Reinforcing the aggression.

Serotonin: Low levels in Pre frontal cortex (lack of decision making, long term consequences) – more impulsive (e.g. considering the short term benefits). This is inhibitory and slows down the brain activity.

Noradrenaline: High levels. Flight and fight. (overactive SAM system). Offenders are using the fight behaviour. Perceiving threats in their environment which are not. Excitatory.

Q

Neurophysiology AO1

A

Limbic System: emotional regulation and regulation of hormones. Increased dopamine in this area may reinforcing the use of aggression.

Amygdala (in limbic system) – fear response, recognising fear in others. Lower activity found may result in fearlessness, HABs.

Pre frontal cortex – involved in consequential thinking, planning and decision making. Lower activity in this area linked to loss of self control and altered emotion.

Q

Eysenck’s theory of criminal personality (AO1)

A

Nature & Nurture: Biological basis for personality types (see below) but also these personality types make them harder to condition; they don’t learn from the consequences of their actions, lack of concern for others means are less amenable to social norms and are less sensitive to negative consequences.

Criminal Personality is Extrovert, Neurotic & Psychotic
Extraversion
Underactive nervous system – thrill seekers as lack stimulation
Offending is risk taking and thrill seeking as dangerous activities
Neuroticism
Overactive nervous system – flight and fight response
Offender perceive threats and fight when behaviour is non-threatening.
Psychoticism
High levels of testosterone in males
Lack of empathy, impulsivity and aggressive in offenders

17
Q

What are the Cognitive explanations of offending

A

Cognitive Distortions
Hostile Attribution Bias
Minimalisation

Moral Reasoning (Kohlberg)

18
Q

Cognitive distortions (AO1)

A

Irrational or faulty thinking
Hostile Attribution Bias (HAB)
Misinterpreting cues
Perceiving behaviour as a threat; when behaviour is innocent.
Lead to an aggressive response or aating to defend themselves (flight & fight)
E.g. Accidently hitting someone with your shoulder walking past, seen as starting a fight.

Minimalisation
Downplaying responsibility for the offence
Reduce feelings of guilt for own actions
Putting the blame onto the victim
E.g. if they hadn’t of worn those clothes…

19
Q

Moral Reasoning (AO1)

A

Pre-conventional = offender
Lack of perspective taking (self only)
Punishment: What is moral depends on punishment
Reward: What is moral depends on what the person gains

Conventional
Some perspective taking (some self)
Good boy & Good Girl: What is moral depends on what others think
Law & Order: What is moral considering social order and laws

Post-conventional
Social contract: What is moral based on how society is affected
Ethical Principal Stage: What is moral based on your self chosen ethical principles valued higher than the law

20
Q

Differential association theory (AO1)

A

Criminal behaviour is learned from association with intimate personal groups

Criminal behaviour is learned through the same processes as any other behaviour. E.g. prison being a ‘school of crime’

People learn techniques and attitudes towards crime from those around them

If the number of favourable (pro-crime) attitudes outweigh unfavourable (anti-crime) ones, then a person becomes an offender.

Differential associations may vary in priority (importance of role model), frequency (how often you see them), duration (how long you see them for) and intensity (higher status, more learning that takes place).

General ‘need’ (e.g. for money, poverty, class) is not sufficient explanation for crime because not everyone with those needs turned to crime.

21
Q

Maternal Deprivation (MD)
Explanation and study

A

Separation from maternal caregiver during sensitive period.

14/44 thieves had affectionless psychopathy
12/14 affectionless psychopaths had MD (mother responsible for emotional development)
2/44 non-criminals had MD.

Without a stable maternal figure than the child is likely to become an ‘affectionless psychopath’
Lack of empathy, guilt or feelings for others, impulsive & frequently lie. This has been associated with criminality

22
Q

Explain the types of superego

A

Weak/Underdeveloped superego: absent same-sex parent (cannot resolve fear of castration; by taking on same-sex morals/attitudes; weak morals = offending) Person under ID control.

Harsh/Overdeveloped superego: strict same-sex parent (excessive guilt; use offending as a deserved punishment)

Deviant superego: criminal same-sex parent (superego similar to ID; deviant morals and attitudes – pro crime).

23
Q

Recidivism rates ao1

A

Definition: conviction for an offence within 2 years after release.
Reoffending rate is approx 28.9% (2024)
Reasons;
Institutionalisation
Mental health & addition
Lack of support
Adult offenders had reoffending rates of approx. 28.8% (2024)

Juvenile offenders, reoffending rates of approx 31.4% (young offenders more impulsive) (2024)
Adults released from custodial sentences less than 12 months, reoffending rates 66%. (2024)

24
Q

Recidivism rates ao3

A

Data suggests longer sentences are more effective than short sentences (less time to rehabilitate in prison?)

The recidivism rates only include 2 years after release from prison. Any offending after 2 yrs is not included.

Actual rates of recidivism could be higher than what the data shows (only people who have been caught), therefore we may believe custodial sentences to be more effective than they actually are.

Recidivism data does not distinguish the type of offence, e.g. violent, sexual or non-violent.

68% of offenders who have had no visits during prison go on to reoffend Is enough done to maintain relationships with the outside world?

Economic implications – reoffending cost £18.1bn in 2019.

102 Australian male offenders interviewed. They felt unsupported upon release and said that a greater level of accessible resources, treatment and/or support services after release would help reduce their recidivism

25
Custodial sentencing (ao1)
Incapacitation To keep offenders in prison and away from public for their safety. Long sentences designed for more harmful offences that hurt the public the most. Deterrence Having large sentences to discourage people from committing the offences, hence prevents offending. Retribution Get justice for society “for victims” for the offence done. The more harm done to victim the larger the sentence. Rehabilitation Psychologists will design and manage treatment programmes. Risk assessments, use teachers to educate and offenders, use probation to help with rehab from prison.
26
Psychological effects of custodial sentencing A01- 4 features
Institutionalisation Mental Health Issues Overcrowding and lack of privacy Effects on the family
27
Institutionalisation Explain as feature of Psychological effects of custodial sentencing
Person loses focus on their own autonomy, morals + values and becomes labelled as a prisoner, tends to happen when overcrowded, more violent. Lives to the prisoner label. Zimbardo:- deindividuation & dehumanisation
28
Mental Health Issues Explain as feature of Psychological effects of custodial sentencing
80-90% of offenders have mental health problems (anxiety & depression being most common). Low self esteem, worsened by lack of contact with family, bullying within prison. Leads to increase in suicide and self-harm. An average of 153.2 self harm incidents occur per month in prison (between 2018-19)
29
Overcrowding and lack of privacy Explain as feature of Psychological effects of custodial sentencing
Overcrowding causes violence –making these changes more permanent – could increase future offending. Calhoun & rat study: increased aggression, hypersexuality, stress.
30
Effects on the family Explain as feature of Psychological effects of custodial sentencing
Women offenders:– creates maternal deprivation, affectionless psychopathy. Children, may not want to associate with the parents. They hang out with more anti-social children – increases familial criminal personality. Bowlby’s 44 thieves' study
31
Behaviour modification ao1
Behaviour Modification is about getting offenders to unlearn criminal behaviours, by reinforcing pro-social behaviour and punishing anti-social behaviour (operant conditioning) Prisoners are given neutral tokens (secondary reinforcer) for showing positive behaviours and these can be exchanged for rewards (primary reinforcer). This can include sweets, drinks, recreational activities. Offenders learn to associate the tokens with the primary reinforcers, e.g. food, products, visits (classical conditioning). Behaviour Shaping: Tokens are given for increasingly more complex pro-social behaviour, e.g. politeness, then helping others within the prison.
32
Explain levels of behaviour modification
33
Key aims of anger management
Cognitive restructuring Awareness and challenging irrational thoughts Regulation of arousal learn to control physiological state (awareness of the bodily reaction to stress) Behavioural strategies problem solving skills, strategic withdrawal from stressful situation & social skills
34
Explain the Stress Inoculation Model as feature of anger management
Cognitive preparation Learn about anger, e.g., how it can be adaptive/non-adaptive and how to recognise and challenge their irrational thinking (should & musts) Skill acquisition Taught self regulation & relaxation techniques. They are taught communication skills e.g. (assertiveness - using ‘I’ language, and problem-solving skills. Application training Roleplay stressful situations (given extensive feedback throughout roleplay), then practise in real life setting and write a diary, to review in treatment sessions.
