There is four parts which makes up the cognitive interview.
Recreate the Context
Try to get them to recall everything from before and after the incident (surrounds the memory)
Context- help to cue the memory
Report Every Detail
Trying to get everything without messing it up
'what was --------- wearing?'
'what could you smell?'
Recall the event in a different order
where you normally start at the beginning of what happened, starting at a different point (when gun went off and going back) this helps because it makes you think about it more clearly and carefully.
Changing the perspective
where as you normally recall from your point of view, recall from someone elses view
'what would .......... of seen?'
- 60 experienced police officers from miami interviewed 47 witnesses- everyone gets interviewed once
- second interview (7 police officers done cognitive interview)
- obtained 47% more facts from the cognitive interview
- Tested 51 public volunteers (not students)
- showed police training videos (stimulated violent crimes)
- 2 days later - interviewed by real police officers and they either used the cognitive interview or standard
- significantly more factual information from the cognitive interview than the standard although thte confabulation was equal
- then they tried to use the cognitive interview- 4 different perspectives (one on each person)
- equally good and factual which shows it is worth using all 4
