  • Loftus and Palmer investigated if leading questions would result in inaccurate EWT.
  • Procedure- experiment 1
    • loftus and palmer conducted a lab experiment which investigated the effects of leading questions for memory of a car accident.
    • 45 pps were shown a film of a car accident and were then put into 1/5 conditions. They were then asked about the speed of the car.
    • 'how fast was the car going when they.... with each other?' with one of the words 'smashed, collided, bumped, hit or contacted'
  • results- experiment 1
    • smashed - 41mph
    • collided - 39mph
    • bumped- 38mph
    • hit- 34mph
    • contacted- 31mph
    • CONCLUSION- being exposed to misleading questions can distort memory
  • Loftus and Palmer- experiment two
    • aim - investigated the effects of leading questions
    • procedure - 150 students were split into 3 groups, they were shown a one min video of a car crash. One group were asked how fast the car was going when they smashed into eachother, the others were asked how fast the car was going when they hit eachother, the third group weren't asked anything. One week later they returned and were asked if they saw any broken glass. There was no broken glass
    • results- smashed group- 32% said they saw broken glass. Hit group - 14%. Control group- 12%
  • experiment two (Loftus & Palmer)
    conclusion- the people who were asked using leading questions were more likely to report broken glass. Leading questions distorted the memory of the original event.
  • Gabbert et al investigated if post event discussion affected recall
  • Gabbert et al
    procedure- investigated the memory conformity effects between pairs of participants. Each person in the pair was shown the same simulated crime video, but from different angles. The experimental condition were allowed to discuss what they saw in the video before completing a recall test. The control group didn't discuss
  • Gabbert et al- results
    • percentage of people who recalled details that they had not seen - experimental condition - 71%
    • control group - 0%
