Detecting deception in second‐language speakers

Purpose. We examined whether language proficiency had an impact on lie detection. Methods. We collected video footage of 30 targets who spoke English as their native or second language and who lied or told the truth about a transgression. Undergraduate students (N = 51) then judged the veracity of these 30 clips and indicated how confident they were in their ratings. Results. Participants were more confident when judging native‐language truth‐tellers than second‐language truth‐tellers. In addition, participants were more likely to exhibit a truth‐bias when observing native‐language speakers, whereas they were more likely to exhibit a lie‐bias when viewing second‐language speakers. Conclusions. Given the difficulties and biases associated with second‐language lie detection, further research is needed.     

Detecting deception in suspects: verbal cues as a function of interview strategy

Research on deception has consistently shown that people are poor at detecting deception, partly due to lack of consistent cues to deception. This research focuses on eliciting verbal cues to deception when questioning suspects who deny crime and how such cues differ due to type of questioning. An experiment examined verbal differences between innocent and guilty mock suspects (N=96) as a function of veracity and interview style (Free recall, Probes, or Free recall plus Probes). Guilty (vs innocent) suspects omitted more crime-relevant information and their statements were more likely to contradict the evidence, showing that statement–evidence inconsistency was a cue to deception. This cue to deception was more pronounced when the interview contained probes. Lie-catchers (N=192) obtained an accuracy rate higher than chance (61.5%) for detecting deceptive denials. Implications for further research on verbal cues to deception are discussed.     

Volition, deception, and the evolution of justice

Criminal justice is inextricably associated with the attributive concept of volition. Although the voluntary-involuntary distinction is subjectively vivid, causal research shows its poles to be inseparable, i.e., the dichotomy is deceptive. Why a bulwark of civilization should be founded on paradox, may be clarified by examining the role of self-deception in man's evolutionary heritage. Natural selection for an optimal degree of self-deception probably occurred, both to facilitate deception of others and to foster human cooperation. This contributed to the evolution of psychiatric disorders, the voluntary-involuntary continuum, and large scale social systems. Society and its members reach an equilibrium within the truth-deception continuum, manifest in individuals by conscious versus unconscious and voluntary versus involuntary, and in society by tension between what actually occurs (realism) and its organizing ideals (idealism). Three legal models of criminal justice are understood in this context: The (1) utilitarian, most realistic, is essential to social survival but vulnerable to abuse; (2) rehabilitative, at an opposite idealistic pole, better supports the image of social beneficence that helps to bind society's members; (3) retributive, most heavily grounded in volition, puts greater emphasis on individual autonomy, and reciprocally modulates the other models. All are legitimized by evolutionary traditions that antedate homo sapiens, and none is sufficient in itself. Elements of all three models necessarily coexist within any existing society, their relative strength varying with its collective values, prosperity, and perceived safety.     

Arms control: Focus on denial and deception

Conclusion Arms control continues to be a key element of U.S. national security policy. Yet, to be a constructive part of our national strategy, stringent arms control verification is required. Of late, the government has moved from agreements incorporating effective monitoring methods to multilateral, feel-good agreements that are very difficult, if not impossible, to monitor. Since the United States is not going to violate agreements, we could be placed at a long-term strategic disadvantage.     

Imprisoned knowledge: Criminals' beliefs about deception

Purpose. This paper is a survey examining beliefs about cues to deception held by prison inmates, prison personnel and students. In line with the ideas about more beneficial learning structures in the environment of criminals and findings from previous studies, we predicted that the beliefs held by prison inmates would be most consistent with the general pattern found in studies examining objective cues to deception. Method. A total of 326 participants filled out a questionnaire containing questions about cues to deception. The sample consisted of 107 prison inmates from high‐security prisons, 103 prison personnel and 116 students. Both between‐group and within‐group analyses were conducted. Results. In line with previous surveys, students and prison personnel held stereotypical and wrongful beliefs about cues to deception. Prison inmates' beliefs about deception were less stereotypical than the beliefs of prison personnel and students. Conclusions. The results indicate that prison inmates have relatively more insight into the psychology of deception. A reasonable explanation for these findings is that the environment of criminals is beneficial in the sense that they receive more adequate outcome feedback than the other two groups. The results indicate that studying this group may generate useful knowledge about the dynamics of deception.     

Effectiveness of deception detection training: a meta-analysis

Abstract

A meta-analysis was conducted to determine the overall effectiveness of deception detection training and to identify conditions that may moderate training effectiveness. The analysis was based on a total of 16 studies with 30 separate hypothesis tests, representing the behavior of 2847 trainees. Results indicated that the effect of deception detection training on detection accuracy was positive, significant, and of medium magnitude. Moreover, training effectiveness was moderated by the type of training implemented, training content, trainee expertise, and the type of lie told. Discussion centers on implications for training design and implementation.     

Medico-legal knowledge of general practitioners: disjunctions,errors and uncertainties

This article discusses a survey of Victorian general practitioners which investigated doctors' legal knowledge, the impact of law on clinical practice, doctors' current medico-legal information sources and their legal education needs and preferences. Knowledge of legal standards was investigated in relation to three areas: disclosure of risk; ownership of, and access to, medical records; and proxy decision-making. Additionally, the impact of statutory reform in relation to proxy decision-making was explored. Further, doctors' past experience of medico-legal education, current sources of medico-legal information and preferences concerning future medico-legal information were explored. Results indicated that overall, respondents had a very inadequate understanding of relevant law and that relevant statutory standards have had little impact on clinical practice. Professional bulletins and journals were identified as major current legal information sources, whilst printed materials, seminars and conferences were preferred sources of legal information. The authors conclude that there is a significant disjunction between legal standards and doctors' awareness of those standards, thereby creating a significant source of liability for doctors. Results highlight an urgent need to develop legal education programs for general practitioners based on doctors' identified needs and preferences.     

Psychopathy and deception detection using indirect measures

Purpose. The goal of the current study was to examine psychopathy and indirect measures of deception detection. Methods. Undergraduate students (N=444) viewed video clips of adult male offenders telling true and false stories about crimes. For each story, participants rated indirect measures of deception (thinking hard, nervousness, emotional arousal, and attempting to control behaviour) and credibility. Participants also chose the story they believed to be true and rated the confidence in their decision. Offenders were rated on the psychopathy checklist – revised. Results. Consistent with past research, deception detection accuracy was at chance level and unrelated to confidence. Ratings on indirect measures by undergraduates did not distinguish true and false statements in offenders. Psychopathic offenders were less successful at deception than non‐psychopathic offenders. Psychopathic traits were associated with lower perceived credibility during deception and ratings of thinking harder while lying. Conclusions. The results suggest that indirect measures of deception detection may be less useful in offender samples. Further, the findings are consistent with the general inability of psychopathic offenders to demonstrate superior deception skills in empirical studies. Indirect measures of deception uniquely related to psychopathic traits offer new insight into the relationship between psychopathy and deception.     

Soviet Sessions: Theory,Practice, and Problems

In the period leading up to the 27th Congress of the CPSU, a landmark in the life of our country, it is one of the important tasks of science and practice to undertake a thoroughgoing analysis of those positive changes that have emerged in recent years in the activity of the soviets of people's deputies, to endeavor a critical assessment of the work so far completed, to exchange opinions on ways to effect possible and necessary changes for the better in their activity and to enhance their role in the system of socialist democracy. The period between the 26th and 27th Party Congresses has seen a considerable rise in the level of leadership by the bodies of state power in respect to economic and sociocultural construction throughout the entire soviet system. The role of the soviets has broadened in all state activity, their influence on the growth of the economy has increased, there is now more coordination in economic and sociocultural construction and in providing consumer and other services to the population, and more attention is being devoted to securing legality and law and order, and protecting the rights and lawful interests of citizens. All these things have been furthered by the CPSU's unflagging observance of the constitutional foundations to the organization and activity of the soviets, by the broadening of their powers, and by strengthening the material and financial basis and the personnel resources of the bodies of state power and government.     

Detection of deception with fMRI: Are we there yet?

A decade of spectacular progress in functional magnetic resonance imaging (fMRI) technology and systems neuroscience research has so far yielded few changes in our daily lives. The dearth of clinical applications of this prolific and academically promising research tool began raising the eyebrows of the public and the research funding agencies. This may be one of the reasons for the enthusiasm and interest paid to the growing body of literature suggesting that blood oxygenation level‐dependent (BOLD) fMRI of the brain could be sensitive to the differences between lie and truth. The word ‘differences’ is critical here since it refers to the often‐ignored core concept of BOLD fMRI: it is only sensitive to differences between two brain states. Thus, available studies report using fMRI to discriminate between lie and truth or some other comparative state rather than to positively identify deception. This nuance is an example of the extent to which applied neuroscience research does not lend itself to the type of over‐simplification that has plagued the interpretation of fMRI‐based lie detection by the popular press and the increasingly vocal academic critics. As an early contributor to the modest stream of data on fMRI‐based lie detection, I was asked by Dr Aldert Vrij to write a piece in favour of fMRI‐based lie detection, to be contrasted with a piece by Dr Sean Spence presenting an opposite point of view ( Spence, 2008 ). This seemingly straightforward task presented two hurdles: having to respond to the popular as well as scientific view of what lie detection with fMRI is and present a wholly positive view of evolving experimental data.     

The devil is in the detail: deception and consistency over repeated interviews

ABSTRACT

Research indicates that truthful statements typically contain more details than fabricated statements, and that truth tellers are no more consistent than liars over multiple interviews. In this experiment, we examine the impact of (i) multiple interviewers and (ii) reverse order recall on liars’ and truth tellers’ consistency and amount of reported detail over repeated recall attempts. Participants either took part in a mock crime (lying condition) or an innocent event (truth telling condition) which they were subsequently interviewed about in two separate interview phases. Truth tellers provided more details overall, and more reminiscent details than liars. There were no differences between veracity groups for the number of omissions made or repetitions reported. Despite the popular belief that inconsistency is a cue to deception, we found little support for the notion that consistency (or lack of consistency) offers a diagnostic cue to deception. We found little evidence that switching interviewer or recalling in reverse order induced inconsistencies in liars. In fact, due to the number of reminiscent details in truth tellers’ accounts, our findings suggest that accounts provided by liars tend to be slightly more consistent than those provided by truth tellers.

Conditions making for success and failure of denial and deception: Nonstate and illicit actors

Conclusion Deception is integral to illicit organizations. Cover is a strategic necessity that, at a great cost in efficiency, allows illicit organizations the opportunity to achieve their objectives. The revolutionary organization is, in fact, an alternative reality that seeks to be invisible except when it needs to propagate a version of the truth and to bolster the impact of its armed operations. In the case of the truth, remarkably little deception is deployed. The revolutionaries consider their faith to be inviolate and convincing, without need of apology or equivocation. Reality is often visible. Islamic Jihad preached the truth, the IRA hid it for two years and the Sicilian Mafia makes the hidden truth yield public respect. In operational matters, much that takes place underground is focused on maintenance, supply and distribution, command and control, and communication that needs to be hidden but need not otherwise be duplicitous. Secrecy apart, most operations focus on obvious targets. Strategic deception is rare.
