Resource summary

Annotations:

  • This study demonstrated the powerful role that anxiety can play in undermining the accuracy of eyewitness memory
1.1 AIMS
1.1.1 To find out if anxiety during a witnessed incident affects the accuracy of later identification

1.3 FINDINGS
1.3.1 Witnessed man with pen: accurate 49%
1.3.2 Witnessed man with bloodstained knife: 33%
1.4 CONCLUSION
1.4.1 Witness concentrates on weapon and this distracts attention away from appearance of criminal
1.4.2 Sight of weapon induces fear and anxiety which takes away attention from peripheral details
1.5 EVALUATION
1.5.1 SUPPORT: Loftus and Burns (1982)
1.5.1.1 PPs either watched a violent or non-violent short film

1.5.2.1 Lacks ecological validity
1.5.2.2 Field studies of real-life events produced different results
1.5.3 AGAINST: Ethical issues
1.5.3.1 PPs were deceived and may have also been upset upon seeing bloodstained knife
2 YUILLE & CUTSHALL, 1986
2.1 Interviewed 13 witnesses to a real-life shooting
2.1.1 Some of the witnesses were close to the incident; others were more distant
2.2 Gave accurate accounts even months later
2.3 Those closest to event gave the most detail
2.4 Misleading questions had no effect on accuracy
2.5 The most distressed proved the most accurate five months later
2.5.1 Heightened arousal due to anxiety enhanced EWT (in this case)
3 CHRISTIANSON & HUBINETTE, 1993
3.1 Questioned 110 witnesses who had witnesses genuine bank robberies
3.1.1 Some had been victims and others were onlookers
3.2 Victims were more accurate in their recall and remembered more details than bystanders
