- Eye Witness Testimony
- Leading Questions
- Loftus & Palmer(1974)
- experiment 1: 45 people watched clips of car crashes. they filled in a questionnaire with filler Qs and 1 critical one
- the question was "about how fast was the car going when it_____ into the other"
- the blank was filled in with either: smashed, collided, bumped, hit or contacted
- the more severe the verb sounded, the faster the people said the car was
- the blank was filled in with either: smashed, collided, bumped, hit or contacted
- the question was "about how fast was the car going when it_____ into the other"
- why do leading questions affect eye witness testimony?
- Response Bias- people are unsure so the leading question bias' their results
- Substitution explanation- the leading question changes the persons memory
- Experiment 2: similar to experiment 1, but with 150 people and the groups smashed, hit or no question (as a control)
- a week later they were asked "did you see any broken glass?"
- double the amount of people in the smashed group said yes, compared to the other groups. this means substitution is correct
- a week later they were asked "did you see any broken glass?"

- Post Event Discussion
- if witnesses are allowed to discuss what happened they can contaminate their own testimony
- Gabbert et al (2003)
- people are paired and watch a video of the same crime but from different angles, some things could be visable from only one view
- they then discussed what they saw and did a recall test on their own
- 71% of people recalled something they hadn't seen (but gained through discussion)
- they then discussed what they saw and did a recall test on their own
- people are paired and watch a video of the same crime but from different angles, some things could be visable from only one view
