HideShow resource information

1. One weakness?

  • All participants viewed the same footage (apart from the IV changes) for the same amount of time, without any disturbances and then answered the same questions, giving more experimental validity
  • Real witnesses would not see the crime on a video recording, they would have been in the situation itself, this means that distractions and emotions that would have been present in real life and could have affected recall were not available to the pa
  • Pickel also employed independent researchers to score and analyse the questionnaire to make sure that there was no researcher bias in the interpretation of the results.
  • There were 2 procedures
