The cognitive interview involves a number of techniques:mentally reinstate the environmental and personal context of the crime report the incident from different perspective, Recounting the incident in a different narrative order.  Geiselman & Fisher proposed that due to the recency effect, Witnesses are asked to report every detail, even if they think that detail is trivial. Geiselman et al. (1985)Aim: .Method: Results: Conclusion | Geiselman (1985) compared recall of some witnesses who had normal cop interview with those who had done a CI. Means: Normal Cop Interview: 29 correct statements Cognitive Interview: 41 correct statements. Supports the idea that the CI improves recall, perhaps by using cues and context to tease out more detail from witnessesHard to assess effectiveness as CI is composed of several techniques, and different police forces have tended to use different versions of it, making comparisons difficultCI can be time consuming, often requiring more time to do fully than police officers haveGeiselman and Fisher (1997) found that CI works best when used within a short time following a crime rather than a long time afterwards, Could limit their usefulness if it takes too long to find / interview witnesses |
