cognitive interview

• Kohnken conducted a meta analysis and found that the CI was superior to the standard police interview the amount of correct information reported from the witness. Therefore the CI is effective at improving the accuracy of EWT.
• Downsides found by Kohnken for the CI- generated more incorrect information than the standard police interview. therefore the CI may be better at getting pps to report more details, but there is no way of distinguishing between correct and incorrect details
• there are practical issues with the CI, time consuming to carry out, not many officers have received proper training in how to use the technique so it may be carried out incorrectly and not lead to any improvement in EWT
