- cognitive interviews
- used to improve recall and reduce witnesses using their schemas.
- the 4 main techniques in cog interview
- 1. report everything
- everything is mentioned no matter how small. triggers more information
- 2. reinstate context at the the time of the event
- encourage witness to think about environmental factors like weather, smells etc and state cues such as how they felt before and after
- 3. change order of recall
- witnesses are asked to recall event in reverse order making it harder for witnesses to reconstruct event according to schema and stop info being lost.
- 4. change perspective
- asking witnesses to put themselves in another witness' shoes and think about what they may have seen helping to recall events they may not have seen.

- weaknesses
- chenier 2014 found officers in Canadian territory didn't stick to the 80/20 rule, their training was based off interviewing suspects not witnesses
- not useful if info is needed quickly as there's no time to ask witnesses free recall so direct questioning is more likely.
