1. investigating leading questions

   • 13/21 pps
     • all from real situation
       • 7 central 6 peripheral
     • interviewed 3 months after the situation
       • gun shop robbery
       • included 2 misleading questions
         • "did you see the busted headlight"
           • "did you see the yellow car panel"
           • half asked
             • A busted headlight
               • A yellow panel
         • half asked
         • 85% central were accurate
           • 79% peripheral accurate
             • leading questions had little effect (3/13)
               • Accuracy remained high even after 3 months

2. High eco validity

   • looked at a real life situation
     • Meaning higher generalisability
   • Ethics
     • pps were not forced take part
       • Informed consent was gained
     • Practical applications
       • Courts and police can be confident in ewt
         • Shows time has no effect on recall
       • Low reliability
         • witnesses may of spoken to each other
           • study not replicable
         • low Pop validity
           • Ethics
             • pps were mislead (leading questions)
               • they were recalling a gruesome situation
             • oversimplifcation
               • May be down to flashbulb memory
               • opposing evidence
                 • lab study showed leading questions do have an effect
                   • (car speed study)
