Question 5

What is the sample?

Answer 5

70 fingerprint experts - met police

Question 6

What is the procedure?

Answer 6

• smudged fingerprint superimposed on £50 note - ridges obscured
• IV = high or low emotional context
• HC = murder - two shots and killed then suspect fled
• LC = forgery - suspect fled
• crime report = context
• half in each condition (35,35)
• naturalistic elements - work hours, typical conditions

Question 7

What are 3 key results?

Answer 7

1. no significant difference in identification rates between high or low emotional context
2. 52% in HC felt affected
3. 6% in LC felt affected

Question 8

What are two suggestions and how do they link to the study?

Answer 8

1. blind testing protocol = debiasing - need-determination perception
   - forensic experts should be blind to context of the crime = more objective
   - 52% of experts HC felt affected
2. Miller 6 pack method - comparing 5 other fingerprints to the initial suspect fingerprint
   - only had one fingerprint = increased chance of confirmation bias
