• what is post event discussion?


  When co-witnesses to a crime discuss it with each other
• Gabbert et al (2003)


  POST-EVENT DISCUSSION

  *each participant watched a video of the same crime, but from different angles

  *participants then discussed what they had seen, before individually completing a recall test.
• results


  71% of participants incorrectly recalled aspects of the event they couldn't have seen.
• why do witnesses go along with each other

  for social approval or because they believe othere have a better memory
• AO3: Weakness


  - use of artificial materials

  - video is not reflective of real life factors

  - other researchers have found that witnesses of a real armed robbery had accurate recall even after 7 months
• AO3: Weakness

  - Gabberts research lacks external validity

  - foster et al argues that recall as an eyewitness has real world consequences unlike studies

  - real eyewitnesses search their memory with more effort due to the chance of a successful conviction
• AO3: strength


  - such research into misleading info has real life applications

  - important practical use for police

  - loftus said police need to be careful as research into ewt can make a difference in the legal system
