factors affecting eye witness testimony

View mindmap
  • factors affecting eye witness testimony (post event information)
    • witnesses are interviewed some time after the incident, so recall is affected by info they have received after the event
    • experiences of the witness cause them to reconstruct their memory
    • recall is influenced by the media, police, lawyers and other witnesses.
      • discussing the incident with other witnesses can lead to reconstruction of memories as they can fill in the gaps with things they may have missed eg a weapon
      • if 2 witnesses agree on something they saw it makes that detail stronger even if it wasn't true
      • questions by the police can lead to inaccuracy due to leading questions and/or body language
      • in court lawyers for the defendant may use questioning to confuse the witness so memories are reconstructed and/or doubted
    • if the witness has been in therapy and remembers violet childhood some claim these become false memories that have become implant through the therapist
