Sketching routes to elicit information and cues to deceit

• Sketching while narrating involves describing an event while sketching on a blank paper (self-generated sketch) or on a printed map. We compared the effects of self-generated sketches and printed maps on information elicitation and lie detection. Participants (N= 211) carried out a mock mission and were instructed to tell the truth or to lie about it in an online interview. In the first phase of the interview, all participants provided a free recall. In the second phase, participants provided another free recall or verbally described the mission while sketching on a blank paper or on a printed map. Truth tellers provided richer accounts than lie tellers. Larger effect sizes emerged for the self-generated sketch condition than for the printed map and free recall conditions. This suggests that self-generated sketches are more effective lie detection tools when information on routes and locations is sought.
