Memon and Higham - Cognitive Evidence Collection

• Effectiveness of Context reinstatement

  Context reinstatement used alone obtains as much information as the complete CI procedures
• Effectiveness of Recall from other perspectives


  Possibility that this may lead to the witness fabricating data

  In practice police interviewers tend not to use this element as it may confuse the witness.

  Milne found it doesn't increase the amount of info recalled
• Effectiveness of recall in temporal orders


  More effective to recall info forwards then backwards than x2 forwards

  Milne found the full CI Elicited more info than single conditions except Context reinstatement
• Conclusions

  Mental context reinstatement is the most effective

  Recall from different perspectives appears to be the least effective and could lead their answers
• Comparing the standard interview

  Impossible to control for individual differences in the styles of interviewers
• Comparing the structured interiew

  Much like the Enhanced CI only without the cognitive components for enhancing memory performance
• CI


  Only technique with Context reinstatement so amount of info obtained is the greatest

  and CI produces more info that the structured interview

  Without knowledge of unreported info it is not possible to establish total accuracy
• Quality of Training


  Suggests training was important to encourage the use of CI techniques

  Quality must be considered
• How long was a two day CI training programme suggested for

  2 day
• What does this suggest about potential of officers and roles

  Those who are good interviewers should be guided towards investigative roles

  and poor interviewers should be guided towards other aspects
