Abstract

Abstract: 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.
