improving accuracy of eyewitness testimony: cognitive interview Flashcards
what did Ronald Fisher and Edward Geiselman (1992) argue?
they argued that EWT could be improved if police used better interview techniques when interviewing witnesses.
what are the 4 main techniques for a cognitive interview - ROPE
- report everything
- reinstate the context
- reverse the order
- change the perspective
what does report everything mean in terms of Cognitive interview?
witness encourage to include every single detail of the event.
some memories may trigger others and so they will be able to recall more
what does reinstate the context mean in terms of Cognitive interview?
witness to should return to original crime scene ‘ in their mind’ and imagine environment and their emotions.
- related to context dependent forgetting
what does reverse the order mean in terms of Cognitive interview?
events should be recalled in different chronological order to original sequence
- done to prevent people reporting their expectations of how event must have happened
- prevents dishonesty
what does change perspective mean in terms of Cognitive interview?
witnesses should recall incident from another persons perspective
- done to disrupt the effect of expectations and schema on recall.
- the schema you have for particular setting generate expectations of what would happen and it is the schema that is recalled rather than what actually happened.
the enhanced cognitive interview (ECI)
- fisher et al (!978) developed additional elements of CI to focus on the social dynamics of the interaction.
- eye contact
-recuse anxiety - minimise questions
- open ended questions
improving accuracy of EWT : cognitive interview EVALUATION - the CI is time consuming
- not likely to be used as takes longer than standard police interview
improving accuracy of EWT : cognitive interview EVALUATION - some elements may be more vulnerable than others
- Milne and Bull (2002) found combination of report everything and reinstate the context produced best results
- even if not all elements are used, these should be
- suggests that at least 2 elements should be used to improve police interviews
improving accuracy of EWT : cognitive interview EVALUATION - support for the effectiveness of the ECI
- studies show enhanced CI provides more correct info than standard info
- better chance of catching criminals
improving accuracy of EWT : cognitive interview EVALUATION - variations of CI are used
- studies use different variations
- applies to real-life where methods are adapted
improving accuracy of EWT : cognitive interview EVALUATION - CI creates an increase in inaccurate info
- could increase inaccurate info as well as accurate
