A review of the cognitive interview
Looked at how effective the training for cognitive interview was
- Training should be done by police sergeants rather than academics
- Training should last 2 days=> only have 4 hrs of training isn’t enough
- Only train officers who show potential=> some people are naturally better at interviewing than others
Broke down each part of cognitive interview + reviewed how effective each part was (context reinstatement, report everything, recall from different perspectives + recall in different orders
-Context reinstatement= most effective part of cognitive interviews
Compared cognitive interview with other interview types
- Standard interview= difficult to compare because interviews are conducted very differently from each other
- Structured interview= similar because they create a rapport but different because it doesn’t have the other cognitive parts. GOOD COMPARISON=> similar to make a fair comparison but different enough to see which is more effective
- Guided memory interview= uses context reinstatement but doesn’t have any other factors of cognitive interview. Useful to compare= see how effective other 3 parts of cognitive interview are
Reviewed how much memory increase cognitive interview provided
- Effectiveness of cognitive interview is measured by how much the person can remember in the interview
- Cognitive interviews ask people to report everything= free to say anything to police even if it isn’t relevant
- Normal police=> ‘tell the truth, the whole truth + nothin but the truth’ witnesses will be more careful before saying anything
- Cognitive interview may seem more successful but it isn’t necessarily
Fisher + Geiselman=> cognitive interview
- Report everything= remember everything even if it’s not relevant. Extra details can act ass cues to aid memory of relevant info
- Recall in different temporal orders= witnesses should record the story in different orders than than just beginning to end= can cue details participants hadn’t thought of before
- Context reinstatement= mentally put them back to crime scene- asked to remember the env=> aids context dependant memory (GRANT)
- Recall from different perspectives= witnesses asked to recall things from someone else perspective at the scene
Reid=> 9 steps of interrogation
- Direct positive confrontation= forcefully confronting a suspect with their guilt
- Theme development= thinking of a reason why they would have done it
- Handling denials= cut off + suppress any denials
Fisher + Geiselman=> enhanced cognitive interview
Establishing a rapport=> making witnesses feel at ease + comfortable with officer= aiding memory recall
-Witness informed of what is expected of them=> help to reduce anxiety
Mann=> lie detection techniques
Test police officers ability to know if it’s a truth or lie during police interviews
- Police officers had to judge the truthfulness of people in real life interviews
- Had to decide if it was a lie or truth + how confident they were
- Experience in interviews correlated with truth accuracy + lie accuracy
- More experience an officer has= better at detecting lies
- Good lie detectors rely more on story cues rather than popular stereotypical beliefs (fidgeting )
