Paper 3: Forensic Psychology Flashcards
What is the purpose of offender profiling?
Offender profiling:
The police use offender profiling to identify the characteristics of a criminal, and narrow down the possible suspects. There are 2 approaches to this: the top-down approach and the bottom-up approach.
what is the top-down approach to offender profiling?
The top-down approach (used in the US) starts with pre-defined criminal profiles, based on experience. It works out which of these the criminal fits into. Douglass describes the sequence of the FBI top-down approach.
Assimilation - data from the scene is gathered and examined.
Classification - this data is then classified into one of 2 profiles: organised or disorganised offender.
Organised = higher IQ, planned crime, no evidence left behind, skilled/employed, socially competent, may follow media coverage of crime.
Disorganised = lower IQ, little/no planning, evidence left behind, unkilled/unemployed, socially incompetent, generally will not follow media coverage of crime.
Reconstruction - this involves identifying the timeline of the crime, and trying to reconstruct the behaviour of the offence.
Profile generation - this involves physical/psychological characteristics, beyond those described in organised/disorganised classification.
evaluation for the top-down approach to offender profiling?
Evaluation:
-based on evidence. organised/disorganised offender profiles were developed by the FBI from 36 US murderers, including Ted Bundy and Charles Manson.
-Limited application. Only works for some types of crime. Eg rapists/murderers tend to have a particular way of committing the crime, in which a bottom-up approach may be more useful.
-overly simplistic. Binary organised/disorganised offender. Many offenders do not fit neatly into either category. Eg high IQ individual could commit a spontaneous murder in a fit of rage.
what is the bottom-up approach to offender profiling?
The bottom-up approach.
In the bottom-up approach, the specific details of the crime are addressed first, then the general profile comes second. This is used in Britain.
Investigative psychology is the use of scientific psychology to solve crimes or identify criminals.
A key concept within IP is interpersonal coherence. This means the way in which a criminal behaves when they commit a crime, will be consistent with how they behave in everyday life. Eg an aggressive murderer is likely to be aggressive in everyday life.
Statistical analysis is also used in IP to identify themes or patterns of behaviour. Because of interpersonal coherence, this might also provide details about the criminal and narrow down the range of suspects.
Statistical analysis can also be used to provide info about the offender’s location through geographical profiling, which you use statistical analysis to make inferences about the criminal’s geographical location.
The circle hypothesis suggests that criminals will carry out crimes within a geographical circle, and also predicts that their home will be within this circle.
One study tested the circle hypothesis - locations of sexual assaults were recorded by 45 offenders. They found that 39 of the 45 lived within the circle predicted by the hypothesis. This suggests the hypothesis is generally valid.
The commuter/circle model vs the marauder model.
The circle model = the marauder model. Suggests the offender lives inside the crime circle.
The commuter model suggests criminals will commute to a circle in which the crimes are committed.
evaluation for the bottom-up approach to offender profiling?
Evaluation:
Gives a much wider range of applications. Top-down only works with a particular modus operandi - eg burglaries, rape, murder etc. Bottom up approach can be applied to a far wider range of crimes.
The bottom up approach is more scientific - this is bc it relies on objective, measurable data, eg plotting geographic locations of crimes. Also uses mathematical tools like statistical analysis, whereas top down relies on intuition, or “gut feeling”.
Contrasting evidence: Copson surveyed UK police officers who use the bottom up approach. Only 3% of the profiles resulted in identification of the offender.
what is the ativistic form explanation of criminal behaviour?
biological explanation.
The ativistic form explanation
Lombroso proposed that criminals are biologically different from other humans, and that criminals have more in common with our evolutionary ancestors. His idea is that they are more savage, prehuman species like the neanderthals. He argued that ativism therefore results in having distinctive facial features: eg strong jaw, heavy brow, extra fingers/toes.
He said that different types of criminal may have different types of facial features.
Ativism - ativism is when an ancestral, genetic trait that has disappeared, reappears.
evaluation for the ativistic form explanation of criminal behaviour?
Evaluation:
Widely dismissed by modern day scientists. It is often described as a historical approach, rather than a biological approach.
There are alternative explanations: even if it were true that criminals had different facial structures, the reason for this may be that being considered “ugly” could lead to social discrimination, followed by criminal behaviour. This would have been particularly true at the time Lombroso was designing his theory of criminality.
This idea raises ethical concerns - socially sensitive, as it can lead to stereotyping and discrimination based on the way someone looks. Can be used to justify racial discrimination.
what is the genetic explanation of criminal behaviour?
biological explanation.
The genetic explanation
Several genes have been linked with criminal behaviour: MAOA-L (L stands for low) gene is linked with aggressive behaviour, and therefore with criminal behaviour. The reason for this is bc the MAOA-L gene affects how neurotransmitters like serotonin are processed in the brain. Low version of the gene, means that less MAOA is produced overall, leading to less regulated neurotransmitters.
If a question asks for “genetic explanations” then you can only talk about twin studies
or the MAOA gene but if a question asks for “neural explanations “then you can use the
MAOA gene AS LONG AS your focus is on the high levels of serotonin, which is neural.
evaluation for the genetic explanation of criminal behaviour?
supporting evidence:
There is evidence that supports genetic explanation.
twin/adoption studies: these are a good way to work out whether a psychological condition is caused by genes or not. There has been research done by Christianson. He looked at concordance rates in criminal convictions, from over 3500 pairs of twins. He found that among males, CC rates were 35% among MZ twins, 12% for DZ twins. females 21% MZ 8% DZ.
This shows that the CC rates in criminal behaviour is higher in identical twins who share all their genes, who share all their genes, compared to non-identical twins, who share half their genes.
Mednick - looked at 14k adopted children, and compared the likelihood that they would grow up to engage in crime activity, if they had a criminal vs non-criminal adopted parent. Also looked at whether they had a crim/non-crim biological parent. They found that having a crim bio parent makes it more likely that the child will become crim, vs whether they have a crim adopted parent. Supports the idea that genetics explain crim behaviour.
Weaknesses: if crim behaviour was entirely determined by genes, CC rates would be 100% in MZ twins.
Also methodological issues w twin studies - it is likely MZ twins have been treated similarly, so environment can play a role.
Similar environment for all twins can play a role in CC rates.
what is the neural explanation of criminal behaviour?
biological explanation.
The neural explanation
Brain structures:
Raine compared the brain scans of convicted murderers, with control participants. He found that the murdered had reduced activity in prefrontal cortex among other brain areas, compartment to the control group. many of the criminals also had less brain matter in this area. The
role of the prefrontal cortex includes regulation of emotional behaviour, and so
lower activation or a dysfunction can lead to impulsiveness and lack of selfcontrol which makes a person at increased risk of offending.
Amygdala: The amygdala, found in the limbic system, is a part of the brain
involved in fear, aggression and social interactions and has been implicated in offending. The
activation of the amygdala has been linked to offending with lower levels of serotonin thought to
inhibit the amygdala activity. This lower activation of the amygdala means a person may recognize
a person is afraid but may not feel concern or empathy or really care that they are. These lower
levels of serotonin are also linked to aggression so the combination of lack of empathy and
aggression again increases the risk of offending.
Neurotransmitters: NTs like dopamine and serotonin may explain crim behaviour. This is supported by the MAOA theory - could link to genetic exp.
evaluation for the neural explanation of criminal behaviour?
Evaluation of the neural explanations:
Raine - supporting evidence
Huge ethical issues with this research. Using brain scans to identify potentially violent people is socially sensitive - could lead to discrimination against people with certain brain structures, before they have committed a crime.
Very deterministic - if neural factors are what causes crim behaviour rather than freewill, it may seem unfair to hold people morally/legally responsible for crim activity. Throws judicial system out of the window.
what is eyesnck’s theory of personality as an explanation of criminal behaviour?
Eyesnck’s theory of the criminal personality
Eyesnck suggested that all personality types including criminality are innate, and have a biological basis. He believed the personality types linked to offending were nerotic, extravert and psychotic.
Definitions:
Extraversion – determined by overall level of arousal in a person’s CNS and ANS. High extraversion scorers have an underactive nervous system, so need more stimulation. This leads to sensation-seeking behaviour, which often involves risk-taking. The thrill of committing a crime may lead extraverts to offending behaviour.
Neuroticism – determined by high levels of reactivity in the SNS which means they respond quickly and strongly to threats. This general instability means behaviour is less predictable. Neurotics also experience high levels of emotion, meaning they are more likely to commit a crime in an emotionally charged situation.
Psychoticism – E suggested this personality type after the previous two. He said that psychoticism was influenced by biological factors such as high levels of testosterone. Psychotics are less likely to feel guilt, so concern for other people is less likely to prevent them from committing a crime. Therefore he believed that extraverts and neurotics were less susceptible to this form of condition, which means that they do not easily learn to respond to antisocial impulses with anxiety.
Conditioning – as well as biological factors, E suggested that personality is linked to socialisation processes and how children are taught. For example when children act in immature ways they are punished, so associate anxiety, or other unpleasant emotions, with antisocial behaviour
evaluation of eyesnck’s theory?
Evaluation of eyesnck’s theory.
Application – crime prevention. He suggests that underlying tendencies are detectable in childhood and also linked to the quality of conditioning and socialisation that a child receives. Therefore interventions could be possible for early treatment of delinquency, to reduce the likelihood of offending behaciour later on.
Issues/debates – takes an interactionist approach to the nature/nurture debate. While Eyesnck did believe that personality types were innate due to biology, he did not think that the consequences of these personality types (eg criminality) were inevitable, as this depends on the quality and nature of conditioning in childhood.
Supporting research – prisoners scored substantially higher than a control on all 3 personality types. Suggests there is at least a link between personality type and offending behaviour.
what is kohlberg’s level of moral reasoning theory?
cognitive explanation.
Kohlberg’s level of moral reasoning theory
K proposed a stage theory of moral development (do not NEED to know all the stages, just how it is linked to offending)
In relation to offending behaviour, research has shown that criminals are more likely to reason at the pre-conventional level of the model, whereas non-criminals have generally progressed to the conventional or post-conventional levels.
The pre-conventional level is associated with less mature and more childlike reasining. For example punishment orientation is common – moral reasoning is based on whether or not the act will lead to punishment, and so the offender may commit a crime if they believe that they can get away with it.
Those at stage 2 use reward orientation. This is moral reasoning based on what is to be gained, and so at this level they may commit a crime if they gain rewards in the form of money, possessions, respect, etc.
Stages 1 and 2 are both part of LEVEL 1 – pre-conventional morality.
evaluation for kohlberg’s theory?
Supporting research – ashkar and Kenny found that sexual and non-sexual offenders in a maximum security prison in australia all used a pre-conventional level of moral reasoning when talking about their own offenders. This supports the moral reasoning theory, indicating that Kohlberg’s theory had some validity.
However – A and K also found that when discussing hypothetical unrelated crimes with these offenders, they were able to use a conventional level of moral reasoning, damaging Kohlberg’s explanation and suggesting there may be other factors at play.
Kohlberg’s levels of moral reasoning suffer from beta bias – levels were based on interviews with 58 boys/man. Assumes women would have the same levels of moral reasoning, at the same ages.
Applications - One strength of the cognitive explanations of offending is the implications for treatment. If faulty/disordered thinking leads to offending, then by changing this thinking using CBT it should reduce crime. The police use cognitive restructuring-a process of learning that guides offenders to see their behaviours as a direct result of the choices they make thus avoiding minimalisation and treatment programmes in prisons could incorporate ways to increase offenders’ level of moral reasoning which may help to reduce reoffending. The fact that these ways of reducing offending use the cognitive explanations further support the explanations.
what is the cognitive distortions explanation of criminal behaviour?
Cognitive distortions explanation
Cognitive distortions = errors or biases in people’s information processing system, characterised by faulty thinking. This thery suggests that criminal behaviour is the result of faulty info processing in the minds of ofenders. This fault centres around how criminals interpret other people’s behaviour, and justify their own actions. This theory has two components:
Hostile attribution bias
This is the misinterpretation of other people’s actions, words or expressions as aggressive or provocative. This may trigger a disproportionate and violent response. HAB leads to offending because the offender places the blame for their actions onto external factors, such as justifying assault by saying the victim had an aggressive expression, etc. it could also lead to offending as it gives an excuse for offending and helps to remove guilt.
Minimalisation
Refers to an offender downplaying or denying the seriousness of the offence committed. Could include downplaying the effects of the crime, rationalising why they committed it, or trivialising the acts committed. This can lead to offending as it enables the criminal to justify the offending act to themselves, therefore avoiding feelings of guilt. Eg sexual offenders often justify their actions by saying they were “only being affectionate”. Or knife crime offenders may trivialise the offence by saying something like “everyone carries a knife”.
evaluation for the cognitive distortions explanation?
Hostile attribution bias also has supporting research – schonenberg presented 55 violent offenders with neutral facial expressions. When compared to a matched control group of non-aggressive ppts, the violent offenders were far more likely to perceive the images as angry and hostile. Supports HAB as the offenders were misinterpreting the expressions as aggressive, which allows the to externalise any blame for their violence, reducing guilt.
Applications - One strength of the cognitive explanations of offending is the implications for treatment. If faulty/disordered thinking leads to offending, then by changing this thinking using CBT it should reduce crime. The police use cognitive restructuring-a process of learning that guides offenders to see their behaviours as a direct result of the choices they make thus avoiding minimalisation and treatment programmes in prisons could incorporate ways to increase offenders’ level of moral reasoning which may help to reduce reoffending. The fact that these ways of reducing offending use the cognitive explanations further support the explanations.
what is sutherland’s differential association theory?
Sutherland’s differential association theory (DAT):
This proposes that offending is learnt through socialisation.
Pro-criminal attitudes and behaviours occur through association and relationships with other people – usually family/friends etc. these are the people we learn social norms from, even deviant ones.
Sutherland believes that offending is more likely to occur where an individual’s social group values pro-criminal behaviour in the way that someone who has a group who values anti-criminal behaviour will be less likely to offend. Everybody’s associations are different – differential association.
Expectations of those around us reinforce our behaviours, through acceptance, social approaval etc. if someone is praised by their family for committing a criminal act, thenthis social approval is reinforcing and makes repeat offending much more likely.
Offending behaviour may also be passed on more directly, ex peers may teach each other how to shoplift goods.
evaluation for sutherland’s differential association theory?
Evaluation for DAT:
Supporting research – Osbourne and west found that 40% of sons of convicted criminals also had convictions by the age of 18, whereas only 13% of sons of non-convict fathers had a conviction by the same age.
However – the rate is only 40% - obviously not full support. Indicates an interactionist approach may be more appropriate.
Issues and debates – DAT is environmentally determinist – suggests that offending is caused by socialisation which is often out of someone’s control. Both socially sensitive, and evidence contradicts this – Osbourne and west found 60% of sons of convicts did not have their own conviction by 18.
what is the superego explanation of criminal behaviour?
psychodynamic explanation.
Psychodynamic explanations for offending:
The superego explanation
Blackburn suggested that the superego was one of the main reasons for offending. Criminal behaviour occurs because the ID is insufficiently controlled or moderated because of problems with superego development in the phallic stage. Underdeveloped superego can happen in 3 different ways;
Deviant superego – deviant/criminal same sex parent – this leads to the internalisation of a deviant superego. Identification with the deviant parent in the phallic stage can lead to offending as the person will not feeling guilty about offending.
Weak superego – absence of same sex parents in the phallic stage could mean that a child fails to internalise a fully formed superego. This underdeveloped superego leaves the child to be dominated by ID impulses, leading to offending.
Over-harsh superego – an individual has internalised a superego from the same sex parents that is excessively harsh and punitive. Therefore crimes are committed to fulfil an unconscious desire for punishment.
what is the defence mechanisms explanation of criminal behaviour?
Second psychodynamic explanation – defence mechanisms
These can lea to crime as they allow offenders to unconsciously justify their criminal behaviour, removing the anciety from committing the crime, increasing their chances of reoffending. Several defence mechanisms could explain offending.
Displacement – when the focus of a strong emotion is shifted from its actual target, to a neutral target which might explain why innocent victims are target as substitutes for real objects of anger/frustration such as lashing out at a stranger on a night out, instead of your boss.
Rationalisation – explaining offending behaviour in a rational/acceptable way when it is actually negative. Eg burglars may rationalise their offence by saying that rich people deserve to be burgled because they have much more than everyone else.
Sublimation – when a strong ID impulse is expressed in a more socially acceptable way, so the desire to commit a crime is diluted. Eg someone may vandalise another person’s car out of anger, instead of physically attacking them.
evaluation for the psychodynamic explanations of criminal behaviour?
Evaluation of the psychodynamic explanations for offending:
Psychodynamic expanations are unfalsifiable. No empirical evidence can be provided to support them. Eg there is no research to suggest that children withut a same sex parent during the phallic stage will offend more. It is impossible to test if the reason for offences can be explained with these explanations, due to their abstract nature. Therefore we can only judge the explanations at face value, rather than scientifically. Therefore both the validity and the usefulness of the explanations are weakened.
Issues and debates – psychic determinism. It states that all behaviour, offending included, is pre-determined by the unconscious so is outside of a person’s control, for example offending is determined in the phallic stage by how a person’s superego is internalised. This suggests that a person cannot be held responsible for their crimes as rooted in childhood experiences determined before adulthood and so removes blame and responsibility for a person’s crime which is not compatible with our legal system. A final issue with this psychic determinism is that it suggests that an offender can’t change as offending is determined by the age of 6 so questions the point of rehabilitation for offenders.
Issues and debates – alpha bias. PD explanations arguably greatly exaggerate the differences between males and females.
what is custodial sentencing, and what does it aim to achieve?
Aims of custodial sentencing:
Definition – involves convicted offender spending time in prison/other institution eg young offender’s institute/psychiatric hospital. The main aims are:
Deterrence – two types. General deterrence aims to send a broad message to the general public that criminal behaviour will not be tolerated. Individual deterrence aims to stop an individual from repeating criminal behaviour, to avoid going back to prison.
Incapacitation – to take an individual out of society to prevent them from reoffending – this way they are no longer a threat to the public. Putting offenders eg rapists/murderers mean that these people are no longer a threat.
Rehabilitation – to make the offender into a better person, to reduce the chance of reoffending. According to this aim, prison should provide opportunities to develop skills or to access treatment for problems like drug addiction, as well as giving the offender a chance to reflect on their behaviour. Offenders shouls leave prison ready to be effective members of society.
Retribution – this is the idea that offenders should pay for their actions and is a way for society to get revenge on the criminal. Putting them in prison means that their are suffering the consequences of their actions – the loss of freedom is the consequence.
evaluation of the use of custodial sentencing as a way of dealing with offending behaviour?
Evaluation for custodial sentencing – for or against
Against – recidivism rates
One of the main arguments against using CS for rehabilitation and individual deterrent is recidivism rates. UK has some of the highest in the world – 2014 figures showed that 45.5% of offenders will reoffend within a year of release, and this is even higher at almost 70% for juvinile offenders. This suggests that prison is only an individual deterrent for a select few, and largely does not rehabilitate offenders.
Reoffending rates are also over 50% for those serving a sentence of under 1 year. This calls into question the use of CS for retribution/incapacitation. These recidivism rates show that prison may casue minor offences (which don’t really need “revenge” or protection from the public) to develop into more serious criminal behaviour. Suggests a different approach may be more effective for minor offences.
For – effectiveness of rehabilitation
Some skills-based training eg anger management, reducing drug addiction and social skills training are successful.
Against – psychological effects.
These include brutalisation, institutionalisation, disorders, and labelling.
Rather than rehabilitating people, the figures suggest that prison causes psychological problems such as depression, anxiety and self-harm and that these may continue when the person leaves prison. Suicide rates are considerably higher in prison (3.7 times for men in 2019) than in the general population, as are incidents of self-mutilation and self-harm. As a result it could be argued that custodial sentencing is not carrying out its original functions, but rather putting vulnerable people at risk to themselves.
