Cognitive Interview.

Cognitive Interview.

1. Geiselman et al. (1985)

2. Based on 4 instructions

   • 1) Recreate context
     • Trying to recall an image of the setting including details such as weather, smells and nearby people
   • 2) Report everything
     • Recall any details that you can remember from the incident even if they do not seem related
   • 3) Recall in different orders
     • Encouraged to describe events in reverse order
   • 4) Change perspectives
     • Recall details from the perspective of someone else who was present at the time

3. Bekerian and Dennett

   • Reviewed 27 studies investigating the effectiveness of the Cognitive Interview and in all cases found that the CI has provided more accurate information than other techniques

4. Kohnken

   • Meta analysis of 53 cases
     • When CI was used, there was a 34% increase in the amount of correct information given

5. Milne and Bull

   • Interviewed children and undergraduate students
     • Used either: one component of CI or all 4 components
     • Found no difference in accuracy and detail of recall
       • Implies using one component is just as good as using all

6. Stein and Memon (2006)

   • Brazil - Police interrogation involves torture
     • Trying to introduce CI and compare it to their method
       • CI was superior in finding forensic rich information
