cognitve interview- imprivng EWT
A01
Gieselman developed cognitive interior identifying four key principles that they believed would enhance recall of EWT compared to standard police interview
context reinstatement , report everything,recall from changed perspective, recall in reverse order
CR us when a personal mentally recalls the context of event for example time day weather. These details acts as triggers helping recall more info.
RE is when a person recalls every detail they can remember even those that seem insignificant
CP is when a person considers the event from someone else’s point of view for example the offender
RO where a person recalls the events in reverse order
A01 and A03
Gieselman examined effectiveness using students who watched videos of a simulated crime. Two days later participants were interviewed using standard interview and cognitive.
Those who were used in cognitive interview recall significantly more correct information than those using standard. This guests thar cognitive interview is more effective than a standard interviewer
A03
Limitation- original CI not all of its elements are equally effective or useful
Milne and Bull found that each of the four techniques used alone produced more information than the standard police interview. But they also found that using a combination of report everything and resonate context produced between recall than any of the other elements or combination of them. This confirmed police offices suspicions that some aspects of CI are more useful than others.
This casts doubt on credibility of the overall cognitive interview
Limitation- time consumer
Police offices may be reluctant to use CI because it takes more time and training that the standard police interview
more time is needed to establish report and a witness to be allowed to relax
Acquires special training and many forces do not have the recourses to provide more than a few hours
This suggest that the complete CI as it exists its not a realistic methods for police officers to use and it might be better to focus on just a few key elements
