  • EWT anxiety eval limitation ethical issues
    Ethical issues- Creating anxiety in participants is very risky
    It's potentially unethical bc it may subject ppl to psychological harm purely for the purpose of research
    This is why real-life studies are so beneficial- psychologists interview people who have already witnessed a real-life event, so there is no need to create it
  • EWT anxiety eval strength support for positive effects
    Support for positive effects- Christianson and Hubinette interviewed 58 real witnesses to bank robberies in Sweden
    The witnesses were either victims or bystanders i.e high and low anxiety
    The researchers found that all witnesses showed generally good memories for details of the robbery itself (better than 75% accurate detail)
    Those witnesses who were most anxious (the victims) had the best recall of all
    These findings from actual crimes confirm that anxiety doesnt reduce the accuracy of recall for EW and may even enhance it
  • counterpoint for Christianson and Hubinette eval
    Christianson and Hubinette interviewed their participants several months after the event (4 to 15 months)
    The researchers therefore had no control over what happened to their participants in the interviewing time
    All sorts of things will have happened including discussions with other people about the event, accounts they may have read or seen in the media, the effects of being interviewed by the police, and so on (i.e post-event discussions).
    Therefore, it's possible that a lack of control over confounding variables may be responsible for these findings, invalidating their support
  • EWT anxiety eval limitation weapon focus may not be caused by anxiety
    Pickel proposed that the reduced accuracy of identification due to the weapon focus effect could be due to surprise rather than anxiety
    To test this she arranged for participants to watch a thief enter a hairdressing salon carrying scissors (high threat, low surprise, hand gun (high threat, high surprise), wallet (low threat, low surprise) and a whole raw chicken (low threat, high surprise)
    Identification was least accurate in the high surprise conditions rather than the high threat
    This supports the view that weapon focus effect is related to surprise rather than anxiety
