cognitive interview
method of interviewing eyewitnesses to help them retrieve more accurate memories using 4 techniques based on psychological insights
report everything
witness is encouraged to include every single detail of the event, even if they seem irrelevant or trivial
reinstate the context
the witness returns to original crime scene in their mind and imagine their environment and emotions. then asked to describe what they saw
reverse the order
Events should be recalled in a different chronological order to the original sequence
change perspective
Witnesses should recall the incident from the perspective of some else e.g. another witness or the perpetrator
why is report everything important
Witnesses might not realise that some details are important, and these may trigger (act as cues for) other important memories, leading to more accurate testimonies.
why is reinstate the context important
Recalling how you felt and the environment could enhance recall by preventing context-dependent and state-dependent forgetting
why is reverse the order important
This is to prevent people from reporting their expectations of how the event must have happened rather than the actual events. It also prevents dishonesty as it’s harder to lie when you have to explain something backwards.
why is change the perspective important
This disrupts the effect of expectations and schema on recall. The schema you have for a particular setting (e.g. going into a shop) generate expectations of what would have happened and it is the schema that is recalled rather than what actually happened.
supporting evidence for cognitive interview- Milne and Bull
-found that using report everything and reinstate the context produced better recall
- so some aspects of the CI are more useful
- so these elements improve police interviewing
weakness of cognitive interview from special training
weakness of studies of cognitive interviews- some used enhanced
supporting and undermining evidence of cognitive interviews - Kohnken et al.
