The current experiment examined the effects of combining two interview techniques on information elicitation and lie detection in multiple interviews. Participants were interviewed online over three weeks. Two‐thirds of the participants (n = 114) were presented with the model statement (MS) interview technique in Interview 1 and were asked to sketch and narrate in Interview 2 (MS‐Sketch condition) or vice versa (Sketch‐MS condition). In Interview 3, all participants provided a free recall. The remaining one‐third of participants (n = 61) provided only a free recall in the three interviews. Truth tellers reported more information than lie tellers in all three interviews. In Interview 2, the Sketch‐MS condition elicited more new information and cues to deceit than the other conditions. The results imply that veracity effects are consistent across multiple interviews and the MS is effective for eliciting information and cues to deceit when preceded by an initial recall.

Summary: We experimentally investigated how different mnemonic techniques employed in an interview conducted immediately after an event affected truth tellers' and liars' responses when they were interviewed again after a 2‐week delay. We also compared how verbal accounts changed over time within truth tellers and liars, and how consistent both groups were. Participants (n = 143) were shown a mock intelligence operation video and instructed either to tell the truth or lie about its contents in two interviews, one of which was immediately after watching the video and the other after a 2‐week delay. In the immediate interview, they were asked to provide a free recall and then asked to provide further information via one of three mnemonics: context reinstatement, sketch, or event‐line. In the delayed interview, they were asked to provide only a free recall. Truth tellers reported more visual, spatial, temporal, and action details than did liars both immediately and after a delay. Truth tellers experienced more of a decline in reporting details after a delay than did liars, and this decline was affected by the mnemonic used. Truth tellers thus showed, more than liars, patterns of reporting indicative of genuine memory decay. Liars produced patterns of a “stability bias” instead. Truth tellers and liars were equally consistent between their immediate and delayed statements. [ABSTRACT FROM AUTHOR]
