Q

What is a strength of cognitive interviews?

A
  • P: Strength = evidence shows it works
  • E: Kohnken et al (1999): Meta analysis combined data from 55 studies comparing cognitive interview with the standard police interview
  • E: The CI gave an average 41% increase in accurate information compared with the standard interview. Only 4 studies in the analysis showed no differences between the types of interview
  • L: Shows CI is an effective technique in helping witnesses recall information that is stored in memory but not immediately accessible

Q

What are limitations of cognitive interviews?

A
  • P: Limitation = not all elements are equally effective
  • E: Bull and Milne (2002): Each technique produced more information than the standard police interview
  • E: Using a combination of 1 and 2 produced better recall than any other elements or combinations of them
  • L: Casts doubt on the credibility of the overall cognitive interview
  • P: Limitation = more time consuming
  • E: More time is needed to establish rapport with a witness and allow them to relax
  • E: CI reqiures special training and many forces do not have resources (Kebbell and Wagstuff (1997))
  • L: Suggests it is not a realistic method - better to focus on just a few key elements
