Sketching while narrating is effective for eliciting information and veracity cues in single interviews. In the current research, we tested this technique in multiple interviews. Participants were interviewed three times over three weeks about a genuine (truth tellers) or a fabricated (lie tellers) memorable event. They sketched while narrating in Week 1, Week 2, Weeks 1 and 2, or not at all (verbal statement only). Statements were coded for total, core, peripheral, and common knowledge details, self-handicapping strategies, complications, plausibility, and proportions of complications and core details. In the third interview and across interviews, the Sketch instruction resulted in a higher proportion of core details. Truth tellers reported more total and core details and complications and fewer common knowledge details and exhibited a higher proportion of complications than lie tellers. Truth tellers' stories also sounded more plausible than lie tellers' stories. The interaction effects were not significant. Thus, sketching while narrating seemed to have a similar effect on truth tellers and lie tellers in the current study.
边叙述边草图绘制在单轮访谈中有效地引出信息和真实性线索。在当前的研究中，我们在多轮访谈中测试了这种技术。参与者在三周内分三轮被问及一个真实（说实话者）或虚构（说谎者）的难忘事件。他们在第 1 周、第 2 周、第 1 周和第 2 周或根本不（仅口头陈述）边叙述边草图绘制。陈述被编码为总细节、核心细节、外围细节和常识细节、自我设限策略、复杂性、以及复杂性和核心细节的比例。在第三轮访谈和所有访谈中，草图指令导致更多的核心细节。说实话者报告了更多的总细节和核心细节以及更多的复杂性，而较少的常识细节，并表现出比说谎者更高比例的复杂性。说实话者的故事听起来比说谎者的故事更合理。交互效应不显著。因此，在当前的研究中，边叙述边草图绘制似乎对说实话者和说谎者都有类似的效果。
