Fisher and Geiselman (1992) study
EWT could be improved if police use better techniques in interviews
Report everything - even small details
Reinstate the context - return to the scene literally or mentally - cues are the same at retrieval
Change perspective - disrupts the effect of expectations and schemas on recall
Reverse the order - prevents schemas from filling gaps in memory
Fisher et al (1987) - enhanced cognitive interview
When to make eye contact
Ensure room is free from distractions
Take steps to reduce anxiety
Have the witness speak slowly
Ask open-ended questions
A03 - supportive evidence of improved EWT accuracy - Koenken et al (1999)
Meta-analysis of 55 students compared with police interviews
Found a 30-50% increase in the amount of correct information in the cognitive interview
A03 - practical application - Kebbel and Wagstaff (1999) - limitation
Found that police officers avoid cognitive interview for less severe offences as it requires an extended technique
Reduces practicality of the technique
