Abstract:Recent studies have shown that the usage of evidence is important in suspect interviews. The Strategic Use of Evidence (SUE) framework examines this idea more in depth. It is a conceptual idea for how to affect the suspects' perception of the interviewer's knowledge about a committed crime. This study examines the effectiveness of the 'Shift-of-Strategy' (SoS) approach, which belongs to the SUE framework. The SoS approach (evidence was disclosed after each answer of the suspect) was compared against the Late disclosure of evidence approach (evidence was disclosed at the end of the suspect interview). Participants (N=50) conducted a mock crime and were afterwards interviewed as a suspect. The participants were interviewed with one of two evidence disclosure approaches. In the Late evidence disclosure condition the interviewer asked the participants to freely respond to evidence focused questions before the evidence was disclosed. In the SoS condition the interviewer (a) disclosed a piece of evidence immediately after an evidence focused question had been answered and (b) saved the questions for which critical evidence was missing to be posed in a bulk at the end of the interview. This study is based on a study from Tekin et al. (2015) and mirrors an adjusted form of its setting. However, this study differentiates in regard of the questions asked in the interview for the missing information. Tekin et al. (2015) concentrated on one missing piece of evidence, whereas this study established three pieces of evidence to concentrate on. Thus, the two interview conditions differed in the shift of attention on the missing pieces of evidence. The adapted SoS approach elicited significantly more new crime relevant information than the Late evidence disclosure approach. As an explanation the counter-interrogation strategies of the suspects can be used, as it was expected that the suspects in the SoS approach will shift their strategy from a withholding to a more forthcoming strategy. In fact, this study supports the use of the SoS approach in suspect interviews.
