Criminal Psychology Flashcards
Four stages of the cognitive interview
- Report everything
- Context reinstatement
- Reverse the order
- Change the perspective
Why use the cognitive interview
Want to ask little questions as every question holds the chance of contaminating memory. Every question has been thought about before to evaluate its value.
What does the cognitive interview do that the standard interview doesn’t ?
Breaks normal conversation rules. Allowing us to speak in more detail.
What did Geiselman find about the cognitive interview?
- the CI decreased the witnesses susceptibility to misleading questions and prevented the original memory trace from being altered.
What did Fisher find about the cognitive interview?
Carried out a field test on the use of CI.
Compared performance of police forces before and after CI training. The detectives collected substantially more information after training, most of which was found to be accurate.
What was a downfall of Geiselman?
41 facts in CI compared to 29 however 7 of those 41 were incorrect.
Research also found more confabulation in witness statements when cognitive interview has been used.
What is weapon focus effect ?
The tendency for witnesses who observe an armed criminal to direct their attention toward the weapon so they fail to encode and remember information about the perpetrators physical appearance as accurately as they would have if no weapon had been visible.
What does Loftus say about weapon focus affect?
It occurs due to threat level of the weapon. That is why we focus on it.
Why does pickle say weapon focus effect occurs?
Unusualness. He tested undergraduates who watched a videotape of a gun-armed man. Their descriptions of him were less accurate if he was pictured in a scene where the gun was unusual and not expected, such as at a baseball game rather than at a shooting range.weapon focus effect is diminished when the weapon is anticipated.
What are some gender differences in crime stats?
- 16% of all arrests were of females
- all those prosecuted and sentenced 27% were female and 73% were male
- 95.5% of the prison population is male
What do psychologists agree on with the gender gap?
That it is universal, particularly when it comes to violent crimes.
How could personality and temperament explain gender differences?
- Males more likely to be diagnosed with ASPD (could be diagnostic bias)
- women more likely to be neurotic and males higher in psychoticism
How could labelling theory and SFP explain gender differences ?
- Boys and girls are socialised differently and expectations are different. Girls more supervised, boys encouraged to take risks.
- CJS more likely to label males.
How could XYY be an explanation for gender differences?
- Similar rates of criminality with XXY which led psychologists to conclude it was about the bullying and self-esteem of not living up to the societal idea of typical masculinity.
- XYY only in males
How could brain injury/ damage explain gender differences in criminality?
Males more likely to suffer TBI than females through exposure to risky social behaviour like fighting, sport and car accidents.
Cycle of labelling? Who was is developed by?
- negative label
- self concept
- label reinforcement by community and others
- master status
- self fulfilling prophecy
- deviant career
Developed by Becker
What are brain injuries as a result of sports accidents or falls called?
Acquired brain injuries (ABI)
What are the last things to develop in the brain?
Impulse control and forward planning
What happens if you have ABI?
Can disrupt brain development
Fails to move past reckless, risk-taking behaviours associated with childhood
Destabilise mood, concentration and decision making
Making offending behaviour more likely
What time does brain injury most impact the brain?
Childhood
Who analysed data from 196inmates from a UK jail?
Williams et al
What did Williams et al do?
Analysed data from 196 inmates from a UK jail in 2010
Results of William et al ?
60% of sample recalled a history of one or more heads injury in their youth
This 60% tended to be:
- young at the time of their first offence
- have higher rates of reoffending
- spent more time in prison in the past five years than the rest of the sample
What’s the amygdala?
- almond shaped structure
- located in temporal lobe in both hemispheres of the brain
- directs how we react to threatening situations
How is the amygdala linked to aggression?
Abnormalities in:
- size
- structure
- activity
What did Dustin Pardini do?
- nueroimaging scans on a group of 26 year old men
- divided into normal amygdala size and reduced volume size
- returned 3 years late
Reduced volume size were 3 times more likely to be aggressive, violent and show psychopathic traits than the normal size.
What is XYY syndrome?
1 in 10,000 men are born with an additional Y chromosome.
No effect on testosterone levels or sexual development
Some behavioural and physical differences
Connected to aggression and crime
How does XYY syndrome present physically and behaviourally?
- taller than average
- lower intelligence
- impulsivity
- experience behavioural difficulties
What did Patricia Jacobs et all find about XXY syndrome?
- conducted a chromosome survey of male patients at a state hospital in Scotland
- men with the XXY chromosomal pattern were over-represented in prison populations
- around 15 per 10,000 compared to the general population.
What is Eysenck’s theory called?
Theory of the criminal personality
What are the two dimensions to measure personality?
- EXTRAVERSION-INTROVERSION
- NEUROTICISM-STABILITY
Explain extraversion?
- Crave excitement and stimulation
- prone to engage in dangerous, risk-taking behaviour
- do not condition easily, do not learn from mistakes
- not affected as strongly by punishment as an introvert
Explain Neuroticism?
- nervy and anxious
- difficult to predict
What does Eysenck say the typical criminal personality is?
Extravert-neurotic
What was the third dimension Eysenck added?
Psychoticism
What does psychoticism entail?
An individual who is self-centred, cold and lacks empathy for others
What is labelling?
A theory of how we classify ourselves and others using labels which then defines that person.
What is self-fulfilling prophecy?
A prediction that directly or indirectly causes itself to become true. Due to the positive feedback between belief and behaviour.
