INTERVIEWING WITNESSES

INTERVIEWING WITNESSES

1. BRUCE ET AL

   • Conducted 3 laboratory experiments into the importance of external/internal features in facial recognition
     • Lab experiment using independent measures design
       • 30 staff and students from Stirling Uni
       • Participants were given 10 pictures of celebrities and asked to match the correct composite image to the celebrity from 40 composites given
         • Group 1 was given complete composites
           • Group 2 was given only external feature composites
             • Group 3 was given only internal feature composites
         • 42% of complete composites and external features were correctly matched to the celeb photo, compared to only 19.5% of internal features
           • External features are more important for facial recognition than internal features and faces are processed holistically
     • INTERNAL: NOSE, EYES, EYEBROWS, MOUTH
     • EXTERNAL: HEAD SHAPE, EARS, HAIR

2. FISHER ET AL

   • Aim to study and test the cognitive interview in the field.
   • As a group the seven trained dectetives elicitd 47% more information after training compared to before training
   • CIT is effective in improving information retrival from witnesses/victims
     • Training is effective

3. LOFTUS ET AL

   • Significance difference found with more eye fixations in weapon condition
     • Weapon condition particpants significantly less accurate than control group
     • "People fiaxte longer and more often on unusual or highly informative objects"
   • Has important implications for reliability of eyewitness identification and memory
