The investigative interviewing of eyewitnesses is an important part of the judicial system and is essential in police investigations to identify culpable parties. However, interviewing witnesses to elicit accurate recall is not without some flaws. Researchers have acknowledged that recall of information is a complex process vulnerable to variables which impede the retrieval of accurate information (Gudjonsson, 1996; Loftus, 1979; 1992). To improve witness recall, psychologists developed the Cognitive Interview (CI) procedure to help interviewers retrieve more correct information from witnesses (Fisher & Geiselman, 1992). The use of the CI has been shown to increase accuracy in many populations (Memon, Holley, Wark, Bull, & Koehnken, 1996; Milne & Shaw, 1999). However, there are some criticisms of the CI. For example, the CI may cause confusion for witnesses (Kebbell, Milne, & Wagstaff, 1999), takes longer to administer than a standard police interview (Croft, 1995) and contain components which are reported to undermine the effectiveness of this procedure (Boon & Noon, 1994). This research program utilised three studies in a multimethod approach to evaluate investigative interviewing procedures, from an experimental and applied perspective. The overarching aim of this research was to identify a parsimonious, effective and efficient interview procedure which overcame some of the limitations recognized in the CI. (Author/publisher)
