Cognitive Interviews Flashcards
What is the intro of cognitive interviews?
-Developed by Fisher and Gieselmen
-A technique used by the police to interview witnesses after a crime/incident
-to help facilitate the most accurate and detailed memory as possible
-they use open questions so the witness can expand on their own
Name all four techniques.
-Recall everything
-Context reinstatement
-Recall in reverse
-Recall from changed perspective
Explain recall everything.
-Witness is asked to report all details even those that seem irrelevent
-trigger memory and additional information
-E.G start from the beginning what happened in the morning of the burglary.
Explain context reinstatement.
-Witness is asked to mentally place themselves at the scene and imagine the environment and emotion
-Using context/state dependant cues would hope to trigger recall
-E.G close your eyes…what do you see?
Explain Recall in reverse.
-Witness asked to report what happened in different chronological order
e.g. end to start
-prevent schema, what witness expects to happen and dishonesty
-E.G tell us what happened when u entered the bank?
Explain recall from changed perspective.
-Witness asked to report the incident from another person’s perspective e.g. bank robber
-prevent schema, what they expect to happen
-E.G imagine your the bank robber, what do you see?
What are the evaluation?
-Kohnken et al (support)
-Kohnken et al (against)
-milne and bull weakness
Explain the research to support
Kohnken et al
-using meta analysis of 50 studies comparing CI with Si
-reported that there was a increase of 41% of correct information in CI compared to SI
-therefore supports as a effective technique
-Because helps the witness to recall information stored in the memory which isn’t accessible
Explain the evaluation Kohnken et al contradicts his study with.
-However.although correct information is remembered in CI compared to SI (41%),often incorrect information is also recalled
-this is called false postives and is a weakness of CI
-despite information being collected. if the information is incorrect this can lead to false imprisonment and wasting police time
-reduces it as a effective technique
Explain the valuation of Milne and Bull
-not all techniques used in cognitive interviews are equally effective
-Milne and Bull found that using one of the 4 alone prduces more information than standards interviews
-they also found that by using a combonation og recall everything and context rienstatement it produced better recall than other ellemnt s
-because it mewans ci are always used as a effecttive tehcnique though there ar esome aspects which are useful in producing accurate recall
