Veracity Judgments Based on Complications: A Training Experiment.

Research has shown that complications are more common in truth tellers' accounts than in lie tellers' accounts, but there is currently no experiment that has examined the accuracy of observers' veracity judgments when looking at complications. A total of 87 participants were asked to judge 10 transcripts (five truthful and five false) derived from a set of 59 transcripts generated in a previous experiment by Deeb et al. Approximately half of the participants were trained to detect complications (Trained), and the other half did not receive training (Untrained).

All mouth and trousers? Use of the Devil's Advocate questioning protocol to determine authenticity of opinions about protester actions.

We examined the Devil's Advocate lie detection method which is aimed at detecting lying about opinions. In this approach, participants give reasons for why they hold an opinion in the eliciting-opinion question and counter-arguments to their opinion in a devil's advocate question. Truth tellers (n = 55) reported their true opinion about protestor actions, whereas lie tellers (n = 55) reported the opposite of their true opinion.

The Model Sketch for Enhancing Lie Detection and Eliciting Information.

Background: Sketching while narrating is an effective interview technique for eliciting information and cues to deceit. The current research examined the effects of introducing a Model Sketch in investigative interviews andis pre-registered on https://osf.io/kz9mc (accessed on 18 January 2022).

The effects of sketching while narrating on information elicitation and deception detection in multiple interviews.

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.

Amplifying recall after delays via initial interviewing: Inoculating truth-tellers' memory as a function of encoding quality.

Typically, truth-tellers report more detailed statements when interviewed immediately, compared to after delays (displaying forgetting), whereas liars report statements containing similar amounts of detail when interviewed immediately or after a delay (displaying a metacognitive error). Accordingly, the diagnostic utility of the 'richness-of-detail' cue is reduced after delays. We investigated if initial interviewing can facilitate lie-detection using the richness-of-detail cue in sub-optimal memorial conditions, that is, when (i) interviewing occurred after a three-week delay and (ii) truth-teller's attention during encoding was manipulated.

The effects of a model statement on information elicitation and deception detection in multiple interviews.

Researchers started developing interview techniques to enhance deception detection in forensic settings. One of those techniques is the Model Statement, which has been shown to be effective for eliciting information and cues to deception in single interviews. In the current research, we focused on the effect of the Model Statement in multiple interviews.
