Cognitive interview Flashcards
Who conducted RTS?
Kohnken et al
What did Kohnken do?
They used a meta-analysis of 50 studies comparing cognitive interviews and standard interviews
What did Kohnken find?
They reported that the CI had an increase of 41% in correct information compared to the standard one supporting the cognitive interview
What is a limitation of Kohnken’s research?
Although more information is recalled, often more incorrect items are remembered with a 61% increase of incorrect information aka false positives
Why are false positives a weakness?
Because despite seeming like more information has been collected, if this incorrect it could lead to false imprisonments and wasting police time reducing the effectiveness of the CI
How can false positives have an effect on the economy?
It can waste prison space and police time if there are false imprisonments. Taxpayer’s money could be spent elsewhere to benefit society, reducing the credibility that the CI may have to society
What is a further weakness of the CI?
Not all techniques in the cognitive interview are equally as effective
What did Milne and Bull find?
Found that each of the 4 techniques used alone produced more information than the standard however they also found that using a combination of report everything and context reinstatement produced better recall than any of the other elements.
