Q

what are limitations of the cognitive interview?

A

different police forces use different aspects so it’s hard to evaluate its effectiveness fully

takes more time than is usually available

demands are placed on the interviewer to ‘probe’ effectively

the quantity and quality of CI training is an issue

Q

what does context reinstatement mean?

A

witnesses should be instructed to mentally recreate their physiological, cognitive and emotional states that existed at the time of the original event

Q

what does report everything mean?

A

Witnesses often withhold information because they do not know what is relevant for a police investigation.

To minimize witnesses’ withholding information, interviewers should instruct them to report everything they think about, whether it is trivial, out of chronological order.
