- Loftus ‘87
- 36 students watched 18 scenes
- Experimental group watched a customer take a gun
- Eye movements were tracked
- Asked to pick out the customer from 12 heads and 11% got it right
54
Eye-witness Testimony: Credibility
- Supported by study done by Loftus and Messo ‘87 which provides evidence that language and weapons change memories
55
Eye-witness Testimony: Objection
- The explanation for EWT is not fully understood as it is still being debated whether it is due to unusualness or arousal
56
Eye-witness Testimony: Differences
- EWT is not an objective accurate form of evidence so a conviction should not be made solely based on EWT instead should use DNA evidence as it is more accurate and objective
57
Eye-witness Testimony: Application
- In January 2022 385 people were exonerated by DNA testing since 1981 which 21 being sentenced to death
58
Criminal: Classic Study Generalisability
- Not very generalisable because PP are made up of 45 universities students who most of do not have driving experience
59
Criminal: Classic Study Reliability
- Very reliable as the test can be replicated by anyone as it has a clear standardised procedure
60
Criminal: Classic Study Application
- Applied to questions of accuracy of EWT in court cases as an expert witness
61
Criminal: Classic Study Validity
- Lack of ecological validity because there the PP did not witness the incidents in person meaning they have a lack of emotional connection to the event unlike eye witnesses
62
Criminal: Classic Study Ethics
- No ethical issues as it passed the ethics research board
- The implications of this study undermines and negatively impacts credible testimonies given
63
Criminal Contemporary Study: Generalisability
- Data was taken from actual trials in 4 states over 2 years
- Can be generalised to real cases which are similar to these
64
Criminal Contemporary Study: Reliability
- Data was taken from actual trials unlike many other studies based on court rooms which use mock trials
- It is difficult to replicate but more reliable than mock trials
65
Criminal Contemporary Study: Application
- Jury make-up had and influence on black defendant conviction
- Can be applied to juries in many cases
66
Criminal Contemporary Study: Validity
- Based on real trials meaning ecological validity
67
Criminal Contemporary Study: Ethics
- Deception- jurors do not know that they would be analysed
68
What was the Aim of the Classic Study
- To test their hypothesis that the language used in eyewitness testimonies an alter memories
69
What is the Procedure of the Classic Study
- 45 American students
- Lab exp / Opportunity sampling
- 5 conditions- smashed, hit, collided, bumped and contacted
- 7 films of traffic accidents presented in a random order
- PP asked to describe what happened as if they were an eye witness
- asked how fast the car was going
70
What was the IV of the Classic Study
- Wording of the question
71
What was the DV of the Classic Study
- Speed Reported
72
What are the Result of the Classic Study
- Smashed estimated 9mph faster than collided
- later asked if there was broken glass a week later
73
What are the Conclusions of the Classic Study
- Estimated speed was affected by the verb used
- The verb implied information about the speed which affected the PP memory of the accident
74
What are the Implications of the Classic Study
- Eyewitness Testimonies might be biased by the way they’re questioned

81
Credibility: Juries Decision making
