cognitive interview research

• What research supports the cognitive interview?

  Milne and Bull (2002): Found that when they used a combination of 'report everything' and 'mental reinstatement', participants' recall was significantly more accurate compared to other combinations. This supports cognitive interview as it shows that the components of cognitive interview increase accuracy as Fisher and Geiselman suggested.
• What research goes against the cognitive interview?

  Koehnken et al (1999) found that witnesses recalled more incorrect information when interviewed with the cognitive interview compared to the standard interview technique. This goes against the cognitive interview, as it shows that rather than improving accuracy, it makes it worse.
