In this study, we examined how different types of interviewing (eliciting more complete vs. less complete accounts) used in an interview conducted shortly after an event affected truth tellers' and liars' responses when they were interviewed again after a two‐week delay. Participants ( n = 80) were shown a mock intelligence operation video and told either the truth or lied about its contents in two interviews, immediately after watching the video, and after a two‐week delay. In the immediate interview participants were instructed either to report everything they remembered, or asked spatial questions related to the event. In the delayed interview, all participants were asked to report everything. The differences between truth tellers and liars were slightly larger in the report everything than in the spatial questions condition. Results suggest that an immediate “report everything” instruction can aid to effectively discriminate between truthful and deceptive accounts.
