“…Many aspects of microexpressions need to be elucidated in the future including the lower limit, individual differences in expression and recognition of microexpressions (Bond and DePaulo, 2008;O′Sullivan et al, 2009;Wang and Fu, 2009;Warren et al, 2009), effective methods of training and the retention of training effects (Hurley, 2010;Matsumoto and Hwang, 2011), and automatic brief facial expression analysis systems (Polikovsky et al, 2010;Wu et al, 2010). As for individual differences, in groups closely related to deception detection, such as crime interrogators, national security personnel, visa interviewers, sales personnel, negotiators, and mental health professionals, the expression and recognition of microexpressions might not be the same as for other people.…”

Abstract:Objective: The purpose of this study was to investigate the effects of the duration of expressions on the recognition of microexpressions, which are closely related to deception. Methods: In two experiments, participants were briefly (from 20 to 300 ms) shown one of six basic expressions and then were asked to identify the expression. Results: The results showed that the participants' performance in recognition of microexpressions increased with the duration of the expressions, reaching a turning point at 200 ms before levelling off. The results also indicated that practice could improve the participants' performance. Conclusions: The results of this study suggest that the proper upper limit of the duration of microexpressions might be around 1/5 of a second and confirmed that the ability to recognize microexpressions can be enhanced with practice.

“…Second, the results might have been different if the receivers were professional interviewers or investigators who were trained to detect lies and had experience with lie detection. Although some previous literature has reported that law-enforcement and non-law-enforcement individuals showed similar levels of deception accuracy [4], others have reported that trained detectives were more accurate in detecting deceit [14], particularly when they are asked to judge high stakes lies [17]. To verify training or experience effects on what we reported in our study, testing skilled vs. nonskilled receivers may contribute to a better understanding of our findings.…”

Abstract-We examined sender ethnicity difference in lie detection accuracy by using stimuli obtained in a 2 (Senders' Ethnicity: Asian vs. European-American) x 2 (Veracity Condition: Lie vs. Truth) x 3 (Interview Type) factorial experiment involving a mock crime. European American receivers judged whether the sender was telling the truth or lying and rated their confidence in each video. Only one significant difference was found: Asian senders were judged more accurately than European American senders. Also, the European American receivers were more confident when judging European American senders, but confidence was not related to deception detection. We concluded that an ingroupoutgroup effect did not exist on deception detection but did exist for confidence ratings.

“…This prediction is based on research which indicates that behavioural differences between truth-tellers and liars may increase when there is motivation to provide an accurate or convincing account, such as receipt of positive (monetary) or negative incentives (avoidance of incidents with campus security; e.g., Bradley, 1988;Colwell, Hiscock-Anisman, Memon, Taylor, & Prewett, 2007), or when the stakes of providing an account are high (e.g., O'Sullivan, Frank, Hurley, & Tiwana, 2009;Vrij & Mann, 2001). …”

Truth and Deception in Informants' Accounts of Criminal Admissions

Informants who report admissions to crime can be powerful and dangerous players in the criminal justice system. Some informants, such as jailhouse informants, are considered deceitful, in part because they can receive incentives to report criminal admissions. However, little research has examined the nature of information that informants provide. In particular, no recent published research has examined whether there are valid behavioural cues that distinguish deceptive from truthful informants. In addition, no published study to date has explored whether informants' reports and demeanours are affected by the incentives that they receive. Participants in this study either did or did not hear a criminal admission and then were interviewed one week later about details of the admission they had allegedly heard. Some participants were offered an incentive to report the criminal admission in a way that appeared accurate and forthcoming. The results of this study suggest that there may be behavioural cues emitted during the reporting of criminal admissions that distinguish truthful from deceptive informants. However, the direction of differences for some cues may deviate from other types of witnesses to crime. In addition, the findings of this study indicate that being offered an incentive may induce informants to emit cues during the reporting of criminal admissions that make them appear more truthful, regardless of whether or not they are actually telling the truth. The findings of this study raise concerns about whether informants' honesty should be assessed in the same way as other witnesses, and about potentially negative consequences of offering incentives to informants in exchange for their reports of criminal admissions.
