Deception detection is literally a matter of life and death in many scenarios in intelligence gathering and criminal investigations. While scientific knowledge on techniques to differentiate between truthful accounts and lies evolve, practical constraints limit the effectiveness of training in these techniques, and therefore hinder their implementations. In the present study, we developed an interactive software with computer-generated avatars driven by empirically based algorithms of suspect behavior to develop a tool for practitioners to practice interview techniques in simulated interviews. We recruited 40 participants and gave half of them training in the Strategic Use of Evidence (SUE) technique including the Evidence Framing Matrix (EFM). All participants interrogated an avatar in a fictional terrorism case. Half of the avatars were innocent and truth-telling and half of them were guilty and lying. Participants who received training were better able to detect avatars that were telling the truth, but not lying avatars. Participants who did not receive training labelled all avatars without exception to be liars. In this pilot study, the avatars only had limited response options in some areas the participants asked questions about, which many of them found suspicious. Use of avatar interview technique training seems promising, but the avatars need to be developed further to include a wider pool of answer possibilities. Also, scenarios with varying levels of difficulty need to be developed.
