What is the key study with YUILLE and CUtshall to do with shooting

How many witnesses took part in study and how many saw shooting

Ho many months were witnesses interviewed after

YUILLE AND CUTSHALL

Suggest witnesses recall can be improved by experiencing anxiety

Folllowing actual shooting - witnesses interviewed 4-5 months after

21 witnesses to shop owner shooting a thief dead and 13 witnesses took part in study

Interview compared with o.g police interviews

Witnesses rated for accuracy of recall and level of anxiety felt at time and any emotional problems since event

What was the results for YUILLE AND CUTSHALL

Results

• found ppt reliable and time had negligible impact on recall

• Found those ppt who experienced highest level of stress - most accurate (88% vs 75% to those less stressed)

• Suggest anxiety might even increase accuracy of recall for real world contexts

What is one strength of this area of research

Evidence showin anxiety have positive effects on accuracy of recall

Study interviewed 58 witnesses to actual bank robberies

Some witnesses directly involved (bank workers) and some indirectly involved (bystanders)

Researchers assume directly involved people were more anxious

Found recall was 75%+ across all witnesses

Direct witnesses most accurate

Findings from actual crimes confirm anxiety doesn’t reduce accuracy of recall for EWT and may even enhance

What is the counterpoint

Study where ppt interviewed several months after event (4-15 months)

Researchers had no control on what happened to ppt in interviewing time (PED)

Effect of anxiety may be overwhelmed by these other factors and impossible to assess by time ppt interviews

It’s possible that a lack of control over extraneous variable may be responsible for the findings of that bank robbery study (Invalidates)
