Who devised the Cognitive Interview Technique?
Fisher and Geiselman (1992)
In regards to the legal system, why have psychologists attempted to devise methods to improve retrieval/accuracy of EWT?
EWT is important in the legal system and has serious consequences when/if it goes wrong
In regards to findings, what other reason is there for devising methods to improve retrieval/accuracy of EWT?
Findings regarding unreliability of eye-witness accounts
What is the Cognitive Interview Technique (CI)?
Questioning technique used by police for interviewing witnesses to a crime
What is the purpose of the CI?
To enhance retrieval of information
What are the four main stages of CI?
1. Context reinstatement (CR)
2. Report everything (RE)
3. Recall in reverse order (RO)
4. Recall from changed perspective (CP)
Outline Fisher et al. (1987) study
What did they do?
Observed real interviews conducted by experienced Florida detectives for four months
Outline Fisher et al. (1987) study
What was found?
1) Frequent bombardments of brief, direct, close ended questions
2) Interrupted
3) Questions out of sync with witness' mental representation of event
Outline Fisher et al. (1987) study
Why did they believe interruptions in an interview to be unhelpful?
Broke witness' concentration and encouraged shorter, less-detailed answers
Outline Fisher et al. (1987) study
On the basis of these findings, what are the 8 additional features to the CI Fisher et al. suggested?
1. Actively listening to witness
2. Minimizing distractions
3. Asking open-ended questions
4. Avoiding interruptions
5. Encouraging of imagery
6. Adaptation of language to suit witness
7. Pauses after each response
8. Avoiding judgmental comments
1. Attentiveness
2. Attention span
3. No suggestion of possible answers
4. No breaking concentration
5. Images
6. Harmony
7. Pausing
8. Not being rude
Briefly outline the report everything (RE) stage of CI
Interviewee is encouraged to report each and every detail of the event even if deemed irrelevant - could help trigger key info.
Briefly outline the context reinstatement (CR) stage of CI
Interviewee is encouraged to mentally recreate the environment in their from original incident
What sorts of features from the environment is the interviewee encouraged to remember in CR?
Weather, sights and sounds, thoughts and feelings, events prior
Briefly outline the recall in reverse order (RO) stage of CI
Alternative ways through timeline of interview may be tried i.e. reversing order in which events occurred
Why might reversing the order in which events occurred aid in retrieval?
Due to the recency effect, people recall recent events clearer
Briefly outline the recall from changed perspective (CP) stage in CI
Interviewee is encouraged to recall the event from a number of perspectives: imagining how others who may have been present at the time would have seen it
Supporting evidence for CI
Outline Geiselman et al. (1985) study
What was their aim?
To investigate effectiveness of CI
Supporting evidence for CI
Outline Geiselman et al. (1985) study
What was the procedure? What did participants have to watch?
1) Participants watched film of violent crime
2) Interviewed by policeman using either CI, SI, or hypnosis
3) Errors and correctly recalled facts were noted
Supporting evidence for CI
Outline Geiselman et al. (1985) study
What was found?
Was CI effective?
What had CI led to an improvement in in regards to memory and relevant information?
CI more effective in eliciting facts (average no. 41.2)
Hypnosis (38.0)
SI (29.4)
CI led to better memory of events (witnesses able to recall more relevant info. than in SI)
Real world applications
Stein and Memon (2006)
What did they do?
Tested effectiveness of CI in Brazil: first time this has been done in developing country
What is the current style of questioning in Brazil and what remains prevalent throughout the criminal justice system?
Current style of questioning: interrogative
Prevalent features of CJS: suspects subjected to torture and other forms of maltreatment
Real world applications
Stein and Memon (2006)
What was the procedure?
Women from cleaning staff from large uni. had to watch video of abduction
Real world applications
Stein and Memon (2006)
What was found about CI in comparison to SI?
What did it increase the amount of in regards to the witnesses?
In comparison to SI, CI increased amount of correct info. recovered from witnesses
Real world applications
Stein and Memon (2006)
What else was found in regards to forensics?
CI was better at producing forensic info i.e. a lady was able to give a detailed description of a man holding a gun - later resulted in police being able to establish which abductor was armed
Real world applications
Stein and Memon (2006)
What do these results show?
How is CI legally effective?
CI is effective in the reduction of miscarriages of justice
Supporting evidence for CI
Outline Fisher et al. (1990)
What did they do?
What did they do with the detectives and genuine crime witnesses?
Trained detectives to use enhanced interview techniques with genuine crime witnesses
Supporting evidence for CI
Outline Fisher et al. (1990)
What was found?
What did EIT significantly increase the amount of?
Significantly increased amount of information recalled
Supporting evidence for CI
Outline Kebbel et al. (1999)
What did they do?
Conducted survey of police officers in UK
Supporting evidence for CI
Outline Kebbel et al. (1999)
What was found?
What was there a greater and lesser use of?
The use of CI was prevalent and officers generally found it useful
HOWEVER.
greater use of report everything and context reinstatement stages of CI; lesser use of and recall in reverse order and changing perspective stages
Supporting evidence for CI
Outline Kebbel et al. (1999)
What concerns did the officers express about CI in regards to information and time?
The amount of incorrect info and how long it took to complete interview
Outline Milne and Bull (2002) study
What was the purpose of this study?
What were they testing in regards to the stages of CI?
To Kebbel et al. (1999) findings - some components of CI more effective than others
Outline Milne and Bull (2002) study
What was the procedure?
How did they test the stages of CI?
CI components were either tested by themselves or combined on undergraduates and children
Outline Milne and Bull (2002) study
What was found about the four stages by themselves?
What was the most effective combination?
All four components produced higher recall by themselves than SI
HOWEVER
The most effective combination was CR and RE which was supportive of what the UK officers had suspected
Outline Milne and Bull (2002) study
What is one drawback of this study?
It was conducted in a lab. and is thus artificial
Which area has CI not proved very successful and who discovered this?
Questioning young children

Misleading information given to witness subsequent to the event
Which other two factors (not mentioned above) can also affect EWT accuracy?
Previous knowledge and expectations
Evaluation of CI
Why may the use of CI prove problematic and demanding with the interviewer?
Interviewer must 'probe' and conduct interview effectively
Evaluation of CI
Why is it difficult to evaluate the overall effectiveness of CI?
Different police forces used different aspects
Evaluation of CI
What are two criticisms of CI in regards to time and young children and their reliability in recall?
1) Time-consuming
2) Young children have difficulty understanding instructions resulting in less reliable recall in comparison to SI
Evaluation of CI
Legally, how is CI valuable and offer examples of where
Valuable in reduction of miscarriages of justice in countries where this is likely to occur i.e. Brazil
