Three studies in Criminal Psych.
Loftus and Palmer, Yarmey, Yuille and Cutshell
15 of 28
Aim of Loftus and palmer
Post event information can contaminate the original account from the witness. Explore this through the language used in questions.
16 of 28
Procedure of Loftus and Palmer.
45 PT's from Uni of Washington. Shown seven clips of car crashes and asked to estimate speed. language of question changed amongst five groups.
17 of 28
What were the five verbs in Loftus and Palmer?
Smashed. Collided. Hit. Bumped. Contacted.
18 of 28
Findings and conclusion of Loftus and Palmer.
Smashed = 41mph. Collided= 39. Bumped - 38. Hit 34. Contacted - 32. Post event information such as language of questions can interfere with original memory.

Aim of yarmey
To investigate the reliability of EWT using a photo line up and two questions.
20 of 28
Yarmey Procedures
590 Pts - 375 females. Used an opportunity sampling method by approaching people in public places and asking them one of two questions - lost jewellery or directions. Either asked to identify the person in a 6 pic line up 2 minutes or four hours l8r.
21 of 28
Yarmey findings and conclusions.
49% identified the correct person when they were present. 62% noticed when they were not there. Those prepared had better recall. 50% EWT make correct identification but 50% unreliable so shouldn't be so detrimental in court.
22 of 28
Aim of Yuille and Custhell
To investigate the accuracy of EWT using a real life crime and he impact of leading questions on the accuracy of EWT.
23 of 28
Yuille and cutshell procedures.
21 witnesses to a real crime outside a gunshot in vancouver, Caada. Thief fired two shots and owner 6 after robbery and tying up owner. thief died. Police interview asap and researchers 4-5 months after with 13 witnesses. 2 leading questions.
24 of 28
What were the leading questions in Yuille and Cutshell?
Did you see the busted headlight? did you see the yellow panel on the thiefs car?
25 of 28
Findings and conclusion of Y&C.
10 immune to leading questions. police rated central witnesses 85% accurate and guile and cutter found a 70% accuracy rate after 4-5 months. Showing more distressed = better recall so EWT not necessarily inaccurate and can resist leading questions.

Key issue for criminal psych - ARE CRIMINALS BORN OR MADE???
Description - What extent can criminal behaviour be attributed to nature compared to nurture? This will be useful to the justice system as it will help reduce crime if we understand its origin. 64% youth reoffend - we can prevent this if we know why.
27 of 28
Explain the key issue.
Made - SLT; made through imitation of behaviour of models. ASB encouraged by VR, self efficacy, ARRM. SFP; label based on background internalised. Born; serotonin, regulates emotions. Some have low levels = anger = ASB.
