Sketching as an Interview Tool to Elicit Information and Cues to Deceit

The current experiment aims to examine the effects of interview modality when suspects describe routes. Specifically, we will compare the effects of using (a) a printed map sketch with narration, (b) a self-generated map sketch with narration, and (c) a verbal statement without a map sketch on the amount and type of details provided in interviews. A total of 210 participants will carry out a mission and will then be instructed to tell the truth or to lie about it to an interviewer. Interviews will be conducted online via Skype. During the interview, participants will provide a verbal statement while sketching on a printed map or while producing a self-generated sketch of the mission or they will provide a verbal statement only.
