4 techniques of cognitive interview

• Change the order


  Recency effect: recent events more likely to be remembered so details in the beginning and the middle of the crime are more likely to be forgotten and changing the order disrupts influence of schemas reduces accuracy of EWT.
• Change perspective


  The eyewitness tries to recall the events from perspective of others that were present during the crime. Discouraged to fabricate details and only report what other witnesses would have seen.
• Report every detail


  Eye-witness is not to filter out or select what information to report. Everything that they can recall from the event should be described. Eye-witnesses don't know what is important to the police. So even smaller irrelevant details may trigger retrieval of other details.
• Mental reinstatement of the original context

  returning to the original crime scene where cues may trigger recall of details. Also recreate the emotional state at the time of event. Tulving's encoding specifically theory states retrieval is optimised when cues are present at the time of encoding. Mentally recreating the scene aids retrieval of other memories which could help the police.
