Q

What is a strength of the CI? - Empirical evidence to support its effectiveness in improving EWT

A

===> Kohnken et al (1999) conducted comprehensive meta-analysis pooling data from 55 studies. Consistently demonstrated cognitive interview yielded a higher rate of accurate information compared to standard interview. Average 34% increase in correct info. Increases validity of CI and highlights practical benefits in real-life setting

Q

What is a limitation of the CI? - Contradictory research findings

A

===> Despite Kohnken et al’s (1999) reported a maximum 81% increase in accurate info when the CI was used, they also found an increase of 61% in amount of incorrect info and false negatives. Indicates the CI elicits more info but doesn’t guarantee accuracy of that info. False positives may prove tragic in apprehending criminals so there’s a need for further research to understand conditions in which the CI would be most effective

Q

What is a limitation of the CI? - Some aspects are more valuable than others

A

===> Milne and Bull (2002) whilst each individual element is better than a standard interviews, using a combination of ‘report everything’ and ‘reinstate the context’ produced better recall than any others. Results can improve the CI within the police force who have limited time and resources but questions the importance of other aspects of the CI
