A

Less activity in PRE-FRONTAL CORTEX (impulsivity, lack of self control)
AMYGDALA - less activity in the left, more in the right, indicates lack of feeling fear
CORPUS CALLOSUM - less activity = cant grasp long term implications

Q

Hall and player procedure

A

Participants had to look at a £50 note with a fingerprint on, deliberately ambiguous. Low emotion group told suspect tried to pay with fake money, high emotion told suspect shot at somebody. Offered crime scene report. Completed a questionnaire of how they came to their decision, if they read it and whether it effected their analysis.

Q

Hall and player results

A

57/70 had read the crime scene report.
52% of those in the high emotional context believed it had affected their decision, while 6% of those in the low emotional context believed it had affected their decision.
Even though the experts thought their decision had been affected, it hadn’t been as no significant difference was found between the two groups

Q

Dror 2012

A

BOTTOM UP (examine print, identify unique features to make a match) vs TOP DOWN (uses experience + knowledge tp make an assumption about print identity. Used when print is unclear)

Top down = more open to mistakes (ie expectancy bias, selective attention)

Q

Dror 2005

A

27 students, non fingerprint experts, given 96 pairs of prints. Half easy to match, half ambiguous.
High emotional cases found a match 58% of the time, compared to 49% in the low emotional cases.
Suggests that an emotional context influences fingerprint analysis. However, non experts

Q

Linear Sequential Unmasking (LSE)

A
  1. Analyse the crime scene print ON IT’S OWN while looking for and recording any unique features and deciding if there is enough detail to make a comparison – without any additional information about the crime
  2. Later, extra information will then be given in order of importance to the case to help make a comparison (e.g. case report about the type of crime and it’s complexity)
  3. The expert can then revisit and add to their analysis but cannot delete or make changes to initial interpretations. They can also say how confident they are in saying it is a match or not

Miller

A

Looked at hair samples, given one hair from the crime and 6 samples to compare against, 5 are fillers. Experts know most hairs not from suspect = experts are more careful when matching hairs

Q

3 Suggestions for unit 2 (forensics)

A

1) limit info available - about the case, dror found high emotion cases increased number of matches from 49% to 58%
2) use a lineup of other samples, miller suggest 6 pack idea
3) be aware of ‘top down’ cognitive biases. Dror found mistakes from top down, relies on assumptions

25
Dixon et al aim
Dixon et al focused on the Brummie accent and how this could influence a juror’s decision.
26
Dixon et al procedure
listened to a 2 minute transcript of an interview between a police officer (in their 40s) and suspect (in their 20s). The suspect pleaded innocent of the crime they were accused of. Students were asked to complete a 7 point scale from guilty to not guilty after listening to the tape.
27
Dixon et al IVs
accent of the suspect (Brummie or standard), the crime they were accused of committing (white collar - cheque fraud or blue collar - armed robbery) and race of the suspect (black or white).
28
Dixon et al results - most guilty combination
Brummie accent, was described as being black, and was being accused of the blue-collar crime. = significantly higher guilt ratings
29
4 additional studies topic 4 (psy and the courtroom, dixon)
Penrod and cutler Pennington and hastie Sigall and Ostrove Simons and Chabris
30
Penrod and cutler
lab experiment, independent measures Participants (undergrad = experienced jurors) shown one version of a videotaped trial for robbery. One version, eyewitness reported 80% confident, one 100% confident in her identification of suspect 80% confident, found guilty 60% of time, compared to 67% for 100% confident witness
31
Sigall and Ostrove
120 college student (50/50 mf), read account of crime where defendant was female, asked to give sentence. IV = crime (burgle, swindling), attractiveness. The jurors were lenient on an attractive burglar but not an attractive swindler (because they used their looks for their crime)
32
Pennington and Hastie
2 ways presenting evidence - witness order is best first/last, story order is chronological Story order is effective but only when used on one side (otherwise its effectiveness is cancelled out). Story for prosecuting = 78% guilty, both = 59%, defence story = 31% guilty
33
Simons and Chabris
192 p, Harvard undergraduates Simons & Chabris found that on average there was a sustained inattentional blindness of 46% This can be used to discredit eyewitness testimony by saying the witness did not see something that may help defend a suspect Things that increased the unexpected event being seen: video being opaque having an easy task watching a team in a similar (black) colour when the unexpected event is less unusual
34
BONUS topic 4 Broeder
Experimental juries were given audio evidence from a case involving a female driver who was injured as a result of a careless male driver. When she reported she had insurance the payout offered by juries was $4000 higher than without. When she reported having insurance but the judge ruled this as inadmissible evidence (evidence they cannot use in their decision) this increased the payout to $13000 higher than if she didn’t report having insurance. Therefore, evidence ruled as banned receives more focus from jurors.
35
Evaluating mock trials
STRENTHS = ethical, quicker, larger samples, controlled procedure WEAKNESSES = know its not real so decision has no consequences (low ecological), often students
36
Suggestions for reducing influence on jury (topic 4)
Use screens to hide witness/suspect’s appearance (Sigall & Ostrove) Use voice changers/Have a written witness statement (Dixon) Rules for witnesses - don’t report confidence (Penrod & Cutler) Randomise/Have set order of witnesses so lawyers don’t decide (Pennington & Hastie)
37
Suggestions for helping witness
manipulate order evidence presented - pennington and hastie story order train witness - report theyre 100% confident, penrod and cutler change appearance, suit, haircut - sigall and ostrove attractive burgulars
38
Key research topic 3 (collection of evidence)
Memon and higham - a review of the cognitive interview
39
Memon and higham, 4 techniques in cognitive interview
Mental reinstatement of context Report everything Recall from a variety of different perspectives Recall in different temporal orders
40
Mental restraintment of context + eval
ask witness to take themselves back to scene, imagine nouse, smell, ect Milne showed that this alone obtains as much info as whole CI interview procedure however not ethical?
41
Report everything + eval CI
everything, regardless of how irrelevant builds picture for police irrelevant points
42
Recall from variaty of perspectives
describe what others saw, ie other witness, victim, suspect May lead to fabricating data, could confuse witness However milne found evidence for it to still produce accurate data
43
Recall from different temporal orders + eval
recall events in different orders ie backwards, start half way through Geiselman and Callot (1990) found that it was more effective to recall in forward order once, followed by reverse order, rather than to make two attempts at recall from the beginning.
44
4 additional studies topic 3 ( collecting evidence)
Reid GUDJONSSON Mann et al Peace Model
45
Reid
Reid 9 steps technique for interrogation, helps lower anxiety levels + reduce barriers of confession 2) theme development - go thru ways of explaining crime, until one is acceptable 5) procurement and retention of suspects attention - good eye contact, use first name 7) present alternative question - ask a question to leas to admitting guilt, one option more socially acceptable
46
Gudjonsson
Claims there is 4 factors to consider when investigating if a confession is false; DEFENDANT- young, old, IQ, mental disorder? ARREST- more likely false if arrested suddenly, violently, middle of night MENTAL/PHYSICAL STATE- more likely if stressed, anxious, ill, intoxicated INTERROGATION- more likely if coercive, biased, elading interview tactics
47
Mann et al
99 police officers shown 54 video clips from real life police interviews, judge if they're lying or not The best lie detectors rely more on story cues (specifically, contradictions in what suspects are saying) Mann suggest police training to focus on listening, environment emphasize listening (screen)
48
Peace model
Suitable for victim, witness or suspect. Assumes if lying, will contradict too much. P = prepare, list of facts, plot timeline E = engage, with interviewee, form a rapport A = account, clarify, challenge - let them give their account without interruption, ask to clarify then challenge to expose C = closure, close appropriately, maintain rapport E = evaluation, check everything covered
49
Core studies for topic 3 collecting evidence
LOFTUS AND PALMER - found that use of critical word (smashed, hit ect) effect how people remember an event, ie seeing glass, estimating speed GRANT - context dependent memory, found that people perform better in recall and recognition when in the same context that the info was learnt
50
suggestions topic 3 collecting evidence
1) build rapport with witness, peace model ( all 3) 2) use cognitive interview technique, mental reinstatement of context, Memon and higham 3) avoid using leading questions, loftus and palmer found false memory of broken glass
51
Topic 5 crime prevention key research
wilson and kelling
52
wilson and kelling policing in Newark
Wilson and Kelling describe a programme carried out in 28 cities in New Jersey, including Newark. This involved the state putting more officers on foot on the street. After five years, a review showed that there was no decrease in crime rates. However, residents living in the areas where the foot patrols had operated felt more secure.
53
wilson and kelling broken windows theory
Wilson and Kelling claim that we should not underestimate the impact of fear of disorder within a community. They suggest that if a window in a building is broken and not repaired then soon all the other windows in that building will be broken as an unrepaired window is a sign that no-one cares.
54
Wilson and Kelling the way ahead
Wilson and Kelling note that there have been instances of vigilantism, such as the Guardian Angels who patrolled the New York subway, and ‘community watchmen’ who patrol neighbourhoods and challenge strangers. However, they are clear that “the police are plainly the key” if public order is to be maintained because their role makes them responsible for stepping in and their uniform makes them easy to identify by residents as someone who is responsible for helping them. They would support the police carrying out foot patrols, but they note that, with limited resources, they need to target their resources with care: “The key is to identify neighbourhoods that are at the tipping point – where the public order is deteriorating but not unreclaimable….” It is in these areas that broken windows need to be mended straight away.
55
topic 5 crime prevention additional studies
Cohen and Felson Brown Zero Tolerance Policy Ernest-Jones et al
56
cohen and felson
3 factors needed for crime to occur; SUITABLE TARGET, things worth stealing MOTIVATED OFFENDER, someone whos inclined, ability to do so ABSENCE OF CAPABLE GUARDIAN, someone who would deter Even if 1 is missing, reduce crime occurance.
57
Zero tolerance policy
Principle of broken windows applied Subway fare dodging - Teams of up to 10 officers were dressed in casual clothes at subway stations with high levels of fare dodging. A city bus was used to speed up travel of those who were arrested. They found 1/7 arrested had an outstanding warrant for another crime and 1/20 were carrying a weapon. Focus shifted to individuals such as public drunks, those urinating in public or ‘squeegee men’ who demanded money for washing car windows
58
Brown
Brown conducted a study in Birmingham, Newcastle and Kings Lynn to compare levels of antisocial and criminal behaviour (DV) before and after CCTV was introduced (IV). Results found burglaries in Newcastle went down by 56% and criminal damages reduced by 34%.
59
Brown contradiction, BURROWS
Brown conducted a similar study in London, found that in the stations with CCTV, crime fell by 70%, only 38% over whole network. Displaced crime rather than eliminated.
60
Ernest Jones et al
A university cafeteria had an experiment comprising of posters asking the students to clear up litter from their meals. The posters either had eyes on them OR flowers on them (IV). They found a 50% reduction in littering (DV) when the posters featured eyes.
61
Topic 5 crime prevention suggestions
Install CCTV, Brown reduced burglaries 50% Police should be more present in communities, Cohen and felson says lack of capable guardian, wilson and kelling eyes on posters, ernest jones 50% reduction in litter
62
Topic 6 effects of imprisonment key research
Haney et al, Zimbardo's Stanford prison experiment
63
Haney et al aim
To test the dispositional hypothesis – to find out whether the situation or the disposition of the individuals make prison brutal. Researchers predicted that allocation to the role of prisoner or guard would dictate the pp’s behaviour and NOT their personality (disposition)
64
Haney et al sample
75 potential responded to advert, 24 selected judged to be stable, mature. College students in Stanford, didn't know each other. Role allocated randomly
65
Haney et al procedure (guards and prisoners)
GUARDS; maintain reasonable degree of order so prison could function, told not to use physical punishment, worked 8hr shifts and left when not on duty, wore reflective glasses. PRISONERS; were called by their number only, blindfolded to mock prison, given whole experience of a prisoner
66
Haney et al results
The study was stopped after 6 days (it was due to last 2 weeks) due to the cruelty and verbal abuse of the guards and some of the prisoners suffering from high levels of anxiety - leading to 5 being released early. 'Pathological prisoner syndrome’ = the way in which prisoners started to show passivity, dependence and flattened mood. Five had to be released early because of extreme emotional depression, crying, rage, and acute anxiety. ‘Pathology of power’ = the way in which people given the opportunity to exert power over others engage in oppressive behaviour. (NB none of the guards were ever late arriving for their shifts, and on several occasions they stayed on duty for several hours, voluntarily and without complaint) This suggests INDIVIDUAL DIFFERENCES in behaviour
67
Topic 6 effects of imprisonment additional studies
Gillis and Nafekh Restorative Justice Anger management programmes Community Sentences
68
Gillis and Nafekh
Interested in effects of an employment scheme within canadian correctional service. Sample 23,525 on parole. Those on programme took 37 months to reoffend, compared to 11 months with those who didnt take the employment programme
69
RESTORATIVE JUSTICE
Involves offender meeting victim in conference, each explain their side. Both must volunteer. Most effective for violent crime, helps reduce PTSD, prevent reoffending
70
Anger management programmes
3 stages; COGNITIVE PREPARATION, taught to identify situations that triggers outbursts SKILLS ACQUISITION, learn relaxation techniques eg regular breathing APPLICATION PRACTICE, apply skills until natural and automatic in Uk, main course is CALM
71
Community Service
Given out for crimes such as damaging property, assualt, fraud. Court believes less likely to reoffend. In 2017, those given community sentences had a much lower reoffending rate. Cheaper
72
Topic 6 effects of imprisonment suggestions (to reduce reoffending)
1) offer anger management programmes, Uk prisons use CALM 2) Create employment prgrammes, train up prisoners. Gilis and Nafekh found 37 v 11 months 3) Bring in ex-prisoners, BANDURA!!!!!!!!!!
73
Core study to use for crime topic 6? To reduce reoffending
