factors affecting eyewitness testimony post-event discussion

• Co-witnesses to a crime


  Eyewitnesses who discuss events with each other
• Co-witnesses discuss events with each other


  Their eyewitness testimonies may become contaminated
• This is because the co-witnesses combine information from other witnesses and their own memories
• GABBERT (2003) - POST EVENT DISCUSSION

  1. Eyewitnesses watched a short film of a girl stealing money from a wallet

  2. They took part individually or in pairs

  3. Those in pairs were led to believe they were watching the same short film as their co-witnesses, but each saw a different perspective and only one saw the crime

  4. Participants in the pair discussed the event together
