Truth tellers sound more plausible than lie tellers. Plausibility ratings do not require much time or cognitive resources, but a disadvantage is that it measured subjectively on Likert scales. The aim of the current paper was to understand if plausibility can be predicted by three other verbal veracity cues objectively counting their frequency occurrence: details, complications, and verifiable sources. If these objective could predict plausibility, observers instructed pay attention them...

Background/objectives: Practitioners frequently inform us that lying through omitting information is relevant to them, yet this topic has been largely ignored by verbal lie detection researchers. Method: In the present experiment participants watched a video recording of secret meeting between three people. Truth tellers were instructed recall truthfully, and pretend one person (John) was not there. Participants or exposed Model Statement during interview. The dependent variables 'total...

Abstract Lie detection research has typically focused on reports about a single event. However, in many forensic and security contexts, suspects are likely to report several events, some of them may be untruthful. This presents interviewers with the challenge detecting which true not. Varying question format second interview, we examined differences liars' truth‐tellers' statement consistency two events. One hundred fifty participants viewed meeting noncritical critical event were discussed....

In a countermeasures experiment, we examined to what extent liars who learn about the Model Statement tool and proportion of complications (complications/complications + common knowledge details self-handicapping strategies) can successfully adjust their responses so that they sound like truth tellers. Truth tellers discussed trip had made; fabricated story. Participants were Lebanese, Mexican, South-Korean origin. Prior interview did or not receive information (i) working statement (ii)...

Summary In none of the deception studies that used drawings to date, was effect sketching on both speech content and drawing examined, making it unclear what full potential is use as a lie detection tool. A total 122 truth tellers liars took part in study who did or not sketch while narrating their allegedly experienced event. We formulated hypotheses about amount information number complications reported various features drawings. Participants Sketch‐present condition provided more than...

We examined police officers’ ( N = 71) perceptions of statement inconsistency types (within-statement, between-statement, statement-evidence, and within-group inconsistencies). Approximately half the officers reported looking for to detect deception. Officers generally associated contradictions omissions with deception, repetitions reminiscences truthfulness, but they were most likely use contradictions. using statement-evidence more than any other type, believed it was easiest type assess....

Abstract Interviewees sometimes deliberately omit reporting some information. Such omission lies differ from other because all the information interviewees present may be entirely truthful. Truth tellers and lie carried out a mission. reported entire mission truthfully. Lie were also truthful but left one element of In truth tellers' statements, only parts that asked to recall analysed. Interviews via Cognitive Credibility Assessment, Reality Interview, or standard interview protocol....

Background/Aim: has shown that sketching while narrating facilitates the elicitation of information and verbal veracity cues in single interviews. We examined if these effects are retained when suspects their sketch after one week a repeated interview. Method: Participants (N = 173) completed mock mission then told truth or lied about it an immediate interview (interview 1). either verbally reported (Free recall condition) sketched describing what they were (sketch condition). After week,...

Abstract People sometimes lie by omitting information. The information tellers then report could be entirely truthful. We examined whether the truthful that in omission lies contains verbal cues indicating person is lying. made a distinction between (i) essential (events surrounding omission) and non‐essential (the rest); (ii) informing or not participants about key event they witnessed. Participants followed target person. Truth reported all activities truthfully; omitted event. were...

Background We examined a new method to encourage interviewees say more, the ghostwriter method, and its effect on eliciting information cues deceit. Method A total of 150 truth tellers liars either told about trip they made in last 12 months or pretended have such trip. They were allocated Control condition, ‘Be detailed’ condition which encouraged report even small details imagine talking ghostwriter. The dependent variables details, complications, common knowledge self‐handicapping...

Summary Due to time constraints, interviews aimed detect deception in airport settings should be brief and veracity assessments made real time. In two experiments carried out the departure hall of an international airport, truth tellers were asked report truthfully their forthcoming trip, whereas liars lie about purpose trip. Experiment 1, we examined five verbal cues that thought had potential discriminate from short interviews: elaboration disclosing information, checkable details, how...

Background Lying through omitting information has been neglected in verbal lie detection research. The task is challenging: Can we decipher from the truthful a teller provides that s/he hiding something? We expected this to be case because of tellers’ inclination keep their stories simple. predicted tellers provide fewer details and complications than truth tellers, latter particularly after exposure Model Statement. Method A total 44 41 were interviewed about conversation (debriefing...

Background:Investigators often use maps in forensic interviews to verify a route that was taken by suspect obtain additional information, and assess credibility.Method:We examined the effects of level map richness on elicitation information cues deceit. A total 112 participants completed mock secret mission were asked tell truth (to friendly agent) or lie hostile about it an interview. In phase 1 interview, all provided verbal free recall mission. 2, half given detailed included street names...

Abstract Sketching while narrating involves describing an event sketching on a blank paper (self‐generated sketch) or printed map. We compared the effects of self‐generated sketches and maps information elicitation lie detection. Participants ( N = 211) carried out mock mission were instructed to tell truth about it in online interview. In first phase interview, all participants provided free recall. second phase, another recall verbally described Truth tellers richer accounts than tellers....

Sketching while narrating is effective for eliciting information and veracity cues in single interviews. In the current research, we tested this technique multiple Participants were interviewed three times over weeks about a genuine (truth tellers) or fabricated (lie memorable event. They sketched Week 1, 2, Weeks 1 not at all (verbal statement only). Statements coded total, core, peripheral, common knowledge details, self-handicapping strategies, complications, plausibility, proportions of...

Aim: We examined the ability to detect lying about opinions with Devil's Advocate Approach and Verifiability Approach. Method: Interviewees were first asked an opinion eliciting question argue in favour of their alleged personal view. This was followed by a devil's advocate against Since reasons that support rather than oppose are more readily available people's minds, we expected truth tellers' responses include information sound plausible, immediate, direct, clear question. In lie tellers...

Summary This study examines counter‐interrogation strategies employed by liars giving false alibis. Participants ( N = 144) visited a restaurant to buy sandwich (truth‐tellers) or use it as alibi (liars). Half of the were informed they might be asked for drawing setting if interviewed (informed liars). spent either 10 min (high familiarity condition) 30 s (low in restaurant. All participants provide two visuospatial statements, which assessed salient details, nonsalient between‐statement...

Summary Behaviour detection officers' task is to spot potential criminals in public spaces, but scientific research concerning what look for scarce. In two experiments, 52 (Experiment 1A) and 60 2A) participants carried out a mission involving ferry crossing. Half were asked smuggle an object; the other half non‐smugglers. Experiment 2A, confederates appeared approach as if looking someone on ferry. Smugglers, more than non‐smugglers, reported afterwards have felt nervous, self‐conscious,...

Abstract 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 participants ( n = 114) presented with model statement (MS) technique Interview 1 asked to sketch narrate 2 (MS‐Sketch condition) or vice versa (Sketch‐MS condition). In 3, all provided a free recall. remaining one‐third 61) only recall Truth tellers reported more than...

Abstract Researchers have often claimed that the interviewer’s nonverbal behavior such as nodding facilitates rapport building, number of recalled details, and verbal veracity cues. However, there is no experiment to-date isolated effects in information gathering interviews. We thus examined on perceptions accuracy total details provided by truth tellers lie tellers. Participants ( N = 150) watched a video recording then reported it truthfully or falsely to an interviewer. The interviewer...

The classification of statements provided by individuals during police interviews is a complex and significant task within the domain natural language processing (NLP) legal informatics. lack extensive domain-specific datasets raises challenges to advancement NLP methods in field. This paper aims address some present introducing novel dataset tailored for made interviews, prior court proceedings. Utilising curated training evaluation, we introduce fine-tuned DistilBERT model that achieves...

Abstract Lie detection research comparing manual and automated coding of linguistic cues is limited. In Experiment 1, we attempted to extend this line by directly the veracity differences in two software programs (Text Inspector Linguistic Inquiry Word Count [LIWC]) on cue “total details” across eight published datasets. Mixed model analyses revealed that LIWC showed larger total details than Text coding. Follow-up classification both could accurately classify honest false accounts. 2,...
