Loftus 1979
Procedure: One group witnessed a quiet discussion and a man coming out the office with a pen. Another group witnessed a loud discussion and man coming out with a knife.
Findings: 49% of people in group one correctly identifies the man, whereas 33% of group 2.
Conclusion: The witness concentrates on the weapon which distracts attentions from the appearance of the perpetrator.
Evaluation: Loftus and Burns, participants who watched a more violent film recalled less accurately.
Christianson and Hubinette study (next card) with more ecological activity contradicts this findings.
.Participants were decieved, were at risk of psychological harm from seeing a knife.
