Denault, V., Plusquellec, P., Jupe, L. M., St-Yves, M., Dunbar, N. E., Hartwig, M., … van Koppen, P. J. (2020). L’analyse de la communication non verbale: Les dangers de la pseudoscience en contextes de sécurité et de justice [The analysis of nonverbal communication: The dangers of pseudoscience in security and justice contexts].

For security and justice professionals (e.g., police officers, lawyers, judges), the thousands of peer-reviewed articles on nonverbal communication represent important sources of knowledge. However, despite the scope of the scientific work carried out on this subject, professionals can turn to programs, methods, and approaches that fail to reflect...
Para los profesionales de la seguridad y la justicia (policías, abogados, jueces), los miles de artículos revisados por pares sobre comunicación no verbal representan fuentes importantes de conocimiento. Sin embargo, a pesar del alcance del trabajo científico realizado sobre este tema, los profesionales pueden recurrir a programas, métodos y enfoqu...
Since the 9/11 terrorist attacks, research has enveloped numerous areas within the psychological sciences as a means to increase the ability to spot potential threats. While airports took to heightened security protocols, many academics looked deeper into ways of detecting deception within international airport settings. Various verbal and nonverba...
We tested the utility of applying the Verifiability Approach (VA) to witness statements after a period of delay. The delay factor is important to consider because interviewees are often not interviewed directly after witnessing an event. A total of 64 liars partook in a mock crime and then lied about it during an interview, seven days later. Truth...
Sham marriages occur frequently, and to detect them, partners are sometimes interviewed together. We examined an innovative method to detect deceit in such interviews. Fifty‐three pairs of interviewees, either friends (truth tellers) or pretended to be friends (liars), were interviewed about their friendship. Just before the interview, they receive...

Leal, Vrij, Deeb, and Jupe (2018) found—with British participants—that a model statement elicited (a) more information and (b) a cue to deceit: After exposure to a model statement, liars reported significantly more peripheral information than truth tellers. We sought to replicate these findings with Arabs living in Israel. Truth tellers and liars r...
The verifiability approach (VA) is a lie‐detection tool that examines reported checkable details. Across two studies, we attempt to exploit liar's preferred strategy of repeating information by examining the effect of questioning adult interviewees before the VA. In Study 1, truth tellers (n = 34) and liars (n = 33) were randomly assigned to either...
General Audience Summary
Research has shown that a model statement—an example of a detailed report about an event unrelated to the topic of investigation—elicits more information during an interview and that truth tellers and liars report a similar amount of extra information. Interviewees typically underestimate how much information is required fr...
The current study was to test whether reality monitoring and language use could distinguish identity liars from truth tellers when answering outcome questions and unexpected process questions. Truth tellers (n = 30) and liars (n = 30) discussed their identity in a recruitment interview. No differences emerged between truth tellers and liars in the...
Background
‘Interviewing to detect deception’ research is sparse across different Ethnic Groups. In the present experiment, we interviewed truth tellers and liars from British, Chinese, and Arab origins. British interviewees belong to a low‐context culture (using a communication style that relies heavily on explicit and direct language), whereas Ch...
Background
We examined whether the verbal cue, proportion of complications, was a more diagnostic cue to deceit than the amount of information provided (e.g., total number of details).
Method
In the experiment, 53 participants were interviewed. Truth tellers ( n = 27) discussed a trip they had made during the last twelve months; liars ( n = 26) fa...

Symposium accepted to EAPL 2017 (European Association of Psychology and Law) presented in Mechelen, Belgium. These accepted abstracts cover various studies that are diectly applicable to the area of deception detection.
In the current study we tested the utility of applying the Verifiability Approach within an International airport setting. The Verifiability Approach works on the notion that truth tellers provide more verifiable details than liars and has shown to be successful within other empirical deception detection scenarios. 399 airside participants (those o...

It is estimated that 40-70% of applicants lie or embellish on their curriculum vitae. The employment of individuals without the necessary skills or qualifications may be detrimental to industry. This study investigated participants who were asked to lie and tell the truth about their occupation in three conditions: chosen lie, forced lie and truth....
This study investigated the deception detection abilities of teenage offenders and teenage non-offenders who made veracity judgments about 12 videotaped interviewees and also explored the behavioural characteristics of teenage liars and truth tellers. The findings revealed that teenage offenders were significantly more accurate in their credibility...
