Advancing the Shift-of-Strategy approach: Shifting suspects' strategies in extended interviews.

OBJECTIVE: Interviewers often face the challenge of obtaining information from suspects who are willing to speak but are motivated to conceal incriminating information. The Shift-of-Strategy (SoS) approach is an interviewing technique designed to obtain new information from such suspects. This study provides a robust empirical test of the SoS approach using more complex crime events and longer interviews than previously tested as well as testing a new variation of the approach (SoS-Reinforcement) that included a strategic summary of the suspect's statement. We compared this new variation with a standard version of the approach (SoS-Standard) and an interviewing approach that involved no confrontation of discrepancies in the suspects' statements (Direct). HYPOTHESES: We predicted that the two SoS versions would outperform the Direct condition in terms of participants' disclosure of previously unknown information. We also predicted that SoS-Reinforcement would outperform SoS-Standard. Finally, we expected that participants in the SoS conditions would not assess the interview or the interviewer more poorly than participants in Direct. METHOD: A total of 300 participants completed an online mock crime procedure, and they were subsequently interviewed with one of the three interviewing techniques. Following the interview, participants provided assessments of their experiences being interviewed. RESULTS: Participants in both SoS-Standard (d = 0.49, 95% confidence interval [CI: 0.21, 0.78]) and SoS-Reinforcement (d = 0.59, 95% CI [0.30, 0.87]) disclosed more previously unknown information than participants in the Direct condition, but SoS-Reinforcement did not outperform SoS-Standard (d = 0.08, 95% CI [-0.20, 0.36]). Participants in SoS-Reinforcement assessed their experience more negatively than those in Direct. No such differences were observed in the remaining two-way comparisons. CONCLUSIONS: The study provides support for the effectiveness of eliciting new information through the SoS approach and illuminates possible experiential downsides with being subjected to the SoS-Reinforcement approach.

Exploring how members of illicit networks navigate investigative interviews.

This study explored how members of an illicit network navigate investigative interviews probing their crimes. We examined how perceived disclosure outcomes, namely, the projected costs and benefits, affect what members choose to reveal. We recruited N = 22 groups, maximum of six participants per group. Each group assumed the role of an illicit network and planned for possible interviews with investigators probing into the legitimacy of a business the network owns. All participants underwent an interview after the group planning stage. The results indicated that network members navigate the dilemma interviews bring by disclosing information they perceive would likely yield beneficial (or desirable) rather than costly (or undesirable) outcomes. Additionally, much of the participants' sensitivity to potential costs and benefits was explained by the group of which they are a part: different networks likely respond to costs and benefits in unique ways. This work contributes to understanding how illicit networks manage information disclosure in investigative interviews.

Verbal Lie Detection: Its Past, Present and Future.

This article provides an overview of verbal lie detection research. This type of research began in the 1970s with examining the relationship between deception and specific words. We briefly review this initial research. In the late 1980s, Criteria-Based Content Analysis (CBCA) emerged, a veracity assessment tool containing a list of verbal criteria. This was followed by Reality Monitoring (RM) and Scientific Content Analysis (SCAN), two other veracity assessment tools that contain lists of verbal criteria. We discuss their contents, theoretical rationales, and ability to identify truths and lies. We also discuss similarities and differences between CBCA, RM, and SCAN. In the mid 2000s, 'Interviewing to deception' emerged, with the goal of developing specific interview protocols aimed at enhancing or eliciting verbal veracity cues. We outline the four most widely researched interview protocols to date: the Strategic Use of Evidence (SUE), Verifiability Approach (VA), Cognitive Credibility Assessment (CCA), and Reality Interviewing (RI). We briefly discuss the working of these protocols, their theoretical rationales and empirical support, as well as the similarities and differences between them. We conclude this article with elaborating on how neuroscientists can inform and improve verbal lie detection.

Plausibility: A Verbal Cue to Veracity worth Examining? / La credibilidad: ¿señal verbal de veracidad que vale la pena analizar?

Truth tellers sound more plausible than lie tellers. Plausibility ratings do not require much time or cognitive resources, but a disadvantage is that it is 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 that can be measured objectively by counting their frequency of occurrence: details, complications, and verifiable sources. If these objective cues could predict plausibility, observers could be instructed to pay attention to them when judging plausibility, which would make plausibility ratings somewhat more objective. We therefore re-analysed five existing datasets; all of them included plausibility, details and complications and two of them also verifiable sources as dependent variables. Plausibility was positively correlated with all three other tested cues, but mostly predicted by complications and verifiable sources, explaining on average almost 40% of the variance. Plausibility showed larger effect sizes in distinguishing truth tellers from lie tellers than the three other cues, perhaps because the plausibility cue consists of multiple components (complications and verifiable sources). Research has shown that the cues that showed the strongest relationship with veracity typically consisted of multiple components. (AU)

Las personas que dicen la verdad suenan más creibles que las mentirosas. La valoración de la credibilidad no necesita mucho tiempo ni recursos cognitivos, aunque tenga la desventaja de que se mide subjetivamente en escalas Likert. El objetivo de este trabajo es saber si la credibilidad puede predecirse mediante pistas de veracidad verbal que puede medirse objetivamente contando la frecuencia de ocurrencia: detalles, complicaciones y fuentes verificables. Si estas pistas cognitivas pudieran predecir la credibilidad se podría instruir a los observadores a que les presten atención al valorar la credibilidad, lo que haría que esta fuera algo más objetiva. Con esta intención reanalizamos cinco conjuntos de datos, todos los cuales incluían credibilidad, detalles y complicaciones y dos de ellos además fuentes verificables como variables dependientes. La credibilidad correlacionaba positivamente con las otras tres pistas que se probaron, predicha sobre todo por las complicaciones y las fuentes verificables, que explicaban de media casi el 40% de la varianza. La credibilidad mostró tamaños de efecto al distinguir personas que decían la verdad de las que mentían mayores que las otras tres pistas, tal vez porque la señal de plausibilidad tiene varios componentes (complicaciones y fuentes verificables). Según la investigación, las pistas con una relación más estrecha con la veracidad normalmente constaban de diversos componentes. (AU)

Subjective likelihood and the construal level of future events: A replication study of Wakslak, Trope, Liberman, and Alony (2006).

C. J. Wakslak, Y. Trope, N. Liberman, and R. Alony (2006) examined the effect of manipulating the likelihood of future events on level of construal (i.e., mental abstraction). Over 7 experiments, they consistently found that subjectively unlikely (vs. likely) future events were more abstractly (vs. concretely) construed. This well-cited, but understudied finding has had a major influence on the construal level theory (CLT) literature: Likelihood is considered to be 1 of 4 psychological distances assumed to influence mental abstraction in similar ways (Trope & Liberman, 2010). Contrary to the original empirical findings, we present 2 close replication attempts (N = 115 and N = 120; the original studies had N = 20 and N = 34) that failed to find the effect of likelihood on construal level. Bayesian analyses provided diagnostic support for the absence of an effect. In light of the failed replications, we present a meta-analytic summary of the accumulated evidence on the effect. It suggests a strong trend of declining effect sizes as a function of larger samples. These results call into question the previous conclusion that likelihood has a reliable influence on construal level. We discuss the implications of these findings for CLT and advise against treating likelihood as a psychological distance until further tests have established the relationship.

The mental representation of true and false intentions: a comparison of schema-consistent and schema-inconsistent tasks.

True and false intentions (i.e., lies and truths about one's future actions) is a relatively new research topic, despite the high societal value of being able to predict future criminal behavior (e.g., in the case of an alleged terrorist attack). The current study examined how true and false intentions are mentally represented - the knowledge of which can aid the development of new deception detection methods. Participants (N = 151) were asked either to form a true intention about a future task (i.e., retrieve objects from an office) or to form a false intention about the same task (i.e., prepare a cover story about retrieving objects from an office) to conceal their actual intention (i.e., leave a secret note in the office). The schema consistency of the task was manipulated by presenting participants with a list of office supplies (schema-consistent) or random objects (schema-inconsistent) to be retrieved from the office. The abstractness of mental construal was operationalized as the number of categories used by participants to organize the task-relevant objects into thematic groups. We predicted, based on construal level theory (CLT) and action identification theory, that participants would mentally represent true intentions more concretely (i.e., use a larger number of categories) than false intentions, particularly for schema-inconsistent (versus schema-consistent) future tasks. The results of the study lend no support for these predictions. Instead, a Bayesian analysis revealed strong evidence in favor of the null hypothesis. The findings indicate that predictions from CLT do not readily translate into deception contexts. The results are discussed in light of recent failed attempts to apply CLT to research on true and false intentions, and highlight the need for alternative approaches to the topic.

Reading Lies: Nonverbal Communication and Deception.

The relationship between nonverbal communication and deception continues to attract much interest, but there are many misconceptions about it. In this review, we present a scientific view on this relationship. We describe theories explaining why liars would behave differently from truth tellers, followed by research on how liars actually behave and individuals' ability to detect lies. We show that the nonverbal cues to deceit discovered to date are faint and unreliable and that people are mediocre lie catchers when they pay attention to behavior. We also discuss why individuals hold misbeliefs about the relationship between nonverbal behavior and deception-beliefs that appear very hard to debunk. We further discuss the ways in which researchers could improve the state of affairs by examining nonverbal behaviors in different ways and in different settings than they currently do.

Drawing what lies ahead: False intentions are more abstractly depicted than true intentions.

The aim of this study was to examine how people mentally represent and depict true and false statements about claimed future actions-so-called true and false intentions. On the basis of construal level theory, which proposes that subjectively unlikely events are more abstractly represented than likely ones, we hypothesized that false intentions should be represented at a more abstract level than true intentions. Fifty-six hand drawings, produced by participants to describe mental images accompanying either true or false intentions, were rated on level of abstractness by a second set of participants (N = 117) blind to the veracity of the intentions. As predicted, drawings of false intentions were rated as more abstract than drawings of true intentions. This result advances the use of drawing-based deception detection techniques to the field of true and false intentions and highlights the potential for abstractness as a novel cue to deceit.

Do True and False Intentions Differ in Level of Abstraction? A Test of Construal Level Theory in Deception Contexts.

The aim was to examine how people mentally represent alleged future actions-their true and false intentions. In two experiments, participants were asked to either tell the truth (i.e., express true intentions) or lie (i.e., express false intentions) about performing future tasks. Drawing on Construal Level Theory, which proposes that psychologically distant events are more abstractly construed than proximal ones, it was predicted that liars would have more abstract mental representations of the future tasks than truth tellers, due to differences in hypotheticality (i.e., the likelihood of the future tasks occurring). Construal level was measured by a video segmentation task (Experiment 1, N = 125) and preference for abstract or concrete descriptions of tasks (Experiment 2, N = 59). Veracity had no effect on construal level. Speaking against our initial predictions, the data indicate that true and false intentions are construed at similar levels of abstraction. The results are discussed in the light of Construal Level Theory and the emerging psycho-legal research on true and false intentions.

Interviewing Suspects in Denial: On How Different Evidence Disclosure Modes Affect the Elicitation of New Critical Information.

This study examines how different evidence disclosure modes affect the elicitation of new critical information. Two modes derived from the Strategic Use of Evidence (SUE) framework were compared against an early disclosure mode (i.e., the evidence was disclosed at the outset of the interview). Participants (N = 88) performed a mock crime consisting of several actions before they were interviewed as suspects. In both SUE conditions the interviewer elicited and disclosed statement-evidence inconsistencies in two phases after an introductory phase. For the SUE-Confrontation (SUE-C) condition, the interview was introduced in a business-like manner, and the interviewer confronted the suspects with the in/consistencies without giving them a chance to comment on these. For the SUE-Introduce-Present-Respond (SUE-IPR) condition, the interviewer introduced the interview in a non-guilt-presumptive way, presented the in/consistencies and allowed the suspects to comment on these, and then responded to their comments; at all times in a non-judgmental manner. Both SUE conditions generated comparatively more statement-evidence inconsistencies. The SUE-IPR condition resulted in more new critical information about the phase of the crime for which the interviewer lacked information, compared to the Early disclosure condition. A likely explanation for this was that (for the SUE-IPR condition) the interviewer used the inconsistencies to create a fostering interview atmosphere and made the suspects overestimate the interviewer's knowledge about the critical phase of the crime. In essence, this study shows that in order to win the game (i.e., obtaining new critical information), the interviewer needs to keep the suspect in the game (i.e., by not being too confrontational and judgmental).

Partners under Pressure: Examining the Consistency of True and False Alibi Statements.

How to discriminate between honest and deceptive alibi statements holds great legal importance. We examined this issue from the perspective of group deception. Our goals were to (a) compare the consistency between the statements of guilty and innocent suspects and those of their respective alibi witnesses, and (b) to examine the moderating role of object-salience on the level of consistency between their statements. Pairs of truth-tellers provided honest testimonies. Pairs of liars were divided into perpetrators and alibi witnesses. Statements of lying pairs were considerably more consistent than the statements of truth-telling pairs. In addition, both truth-tellers and liars showed lower levels of within-group consistency when recalling less salient details about an event. However, truth-tellers' consistency levels were considerably more affected by salience than were liars' consistency levels. These findings contribute to deception theory and have important implications for the real-life task of distinguishing between true and false alibi statements.

To wait or not to wait? Improving results when interviewing intoxicated witnesses to violence.

Witnesses to violent crimes are often alcohol intoxicated, but few studies have investigated the impact of alcohol on witness reports. This study investigated how alcohol intoxication and time of interview affected reports of intimate partner violence (IPV). One hundred thirty six healthy men (N = 66) and women (N = 70) were randomized to an alcohol group (0.8g/kg for men, 0.75g/kg for women) (N = 70) or control group (N = 66), given juice. Participants consumed drinks in a laboratory setting before they witnessed an IPV scenario. Fifty percent of the intoxicated and sober participants were interviewed ten minutes after viewing the film and all participants were interviewed one week later. For the analyses, participants in the alcohol group were divided into two groups (moderately/highly intoxicated) based on their BAC-level. Ten minutes after viewing the event, highly (BAC = 0.08-0.15) intoxicated witnesses gave shorter, but as accurate, reports as moderately intoxicated/sober witnesses. All witnesses gave shorter and less accurate reports one week later compared to immediately after. However, an immediate interview increased completeness one week later. In general, time and high intoxication made witnesses give less detailed accounts of actions and verbal information, but not of objects. Highly intoxicated witnesses reported less actions and verbal information in all interviews, while information regarding objects was reported to a similar extent. At the present BAC-level, it is beneficial to conduct an immediate free recall interview with intoxicated witnesses to obtain a maximum amount of correct information and minimize the negative effect of time.

Alcohol Intoxicated Witnesses: Perception of Aggression and Guilt in Intimate Partner Violence.

Many witnesses to violent crimes are alcohol intoxicated, but research is lacking regarding how alcohol affects their perception of aggression and guilt. This study investigated to what extent alcohol intoxicated eyewitnesses differed from sober witnesses regarding how aggressive and guilty they perceived the involved parts in an intimate partner violence (IPV) situation. Eighty-seven healthy men ( n = 44) and women ( n = 43) were randomized to an alcohol group (0.7 g/kg) or a non-alcohol group. In a laboratory setting, alcoholic/non-alcoholic drinks were consumed before viewing a film depicting IPV between a man and a woman. Ten min after viewing, in an interview, the participants rated how aggressive and guilty they perceived the involved parts to be. Alcohol intoxicated participants perceived both parts' physically aggressive behavior as comparatively less severe, but their neutral behavior as more hostile. Sober witnesses perceived the man to be the most guilty part, whereas intoxicated witnesses distributed guilt more evenly. Alcohol had a strong but complex impact on the perception of aggression in IPV (i.e., heightened during the neutral interaction and lowered during physical aggression). These results may be explained by the cognitive consequences of alcohol's anxiety-dampening effects. Regarding the asymmetric difference in perceived guilt, stereotypical expectations of gender-appropriate behavior in an IPV situation may need to be considered.

Witnesses stumbling down memory lane: The effects of alcohol intoxication, retention interval, and repeated interviewing.

Intoxicated eyewitnesses are often discredited by investigators and in court, but few studies have examined how alcohol affects witnesses' memory. The primary aim of the present study was to examine how intoxication (alcohol vs. control), retention interval (immediate vs. one week delay), and number of interviews (one vs. two interviews) affect witnesses' memory. The participants (N = 99) were randomly assigned to consume either orange juice or alcohol mixed with orange juice, and they all witnessed a filmed mock crime afterwards. The recall took place either (a) immediately and after a one week delay or (b) after a one week delay only. No main effect of alcohol was found on the quantity or quality of the witnesses' statements. Both intoxicated and sober witnesses recalled more details, and were more accurate, during immediate compared to delayed recall. For witnesses interviewed twice, an average of 30% new details were provided in the second compared to the first interview, and these were highly accurate. In sum, contrary to what one can expect, intoxicated witnesses with a low to moderate blood alcohol concentration (below 0.10%) were reliable witnesses.

Factors Affecting Two Types of Memory Specificity: Particularization of Episodes and Details.

Memory for repeated events is relevant to legal investigations about repeated occurrences. We investigated how two measures of specificity (number of events referred to and amount of detail reported about the events) were influenced by interviewees' age, number of experienced events, interviewer, perceived unpleasantness, and memory rehearsal. Transcribed narratives consisting of over 40.000 utterances from 95 dental patients, and the corresponding dental records, were studied. Amount of detail was measured by categorizing the utterances as generic, specific, or specific-extended. We found that the two measures were affected differently by all five factors. For instance, number of experienced events positively influenced number of referred events but had no effect on amount of detail provided about the events. We make suggestions for future research and encourage reanalysis of the present data set and reuse of the material.

Corrigendum: Detecting Deception within Small Groups: A Literature Review.

[This corrects the article on p. 1012 in vol. 7, PMID: 27445957.].

Detecting Deception within Small Groups: A Literature Review.

Investigators often have multiple suspects to interview in order to determine whether they are guilty or innocent of a crime. Nevertheless, co-offending has been significantly neglected within the deception detection literature. The current review is the first of its kind to discuss co-offending and the importance of examining the detection of deception within groups. Groups of suspects can be interviewed separately (individual interviewing) or simultaneously (collective interviewing) and these differing interviewing styles are assessed throughout the review. The review emphasizes the differences between lone individuals and groups. It focuses on the theoretical implications of group deceit and the reasons why groups need to be understood in terms of investigative interviewing and deception detection if all types of crime-related incidents are to be recognized and dealt with appropriately. Group strategies, consistency within- and between-statements, joint memory, and group dynamics are referred to throughout the review and the importance of developing interview protocols specifically for groups is discussed. The review concludes by identifying the gaps in the literature and suggesting ideas for future research, highlighting that more research is required if we are to obtain a true understanding of the deception occurring within groups and how best to detect it.

Using the Scharff-technique to elicit information: how to effectively establish the «illusion of knowing it all»? / La utilización de la técnica de Scharff para extraer información: cómo crear la «ilusión de saberlo todo» de un modo eficaz?

The Scharff-technique is used for eliciting information from human sources. At the very core of the technique is the «illusion of knowing it all» tactic, which aims to inflate a source's perception of how much knowledge an interviewer holds about the event to be discussed. For the current study, we mapped the effects following two different ways of introducing this particular tactic; a traditional way of implementation where the interviewer explicitly states that s/he already knows most of the important information (the traditional condition), and a new way of implementation where the interviewer just starts to present the information that s/he holds (the just start condition). The two versions were compared in two separate experiments. In Experiment 1 (N=60), we measured the participants’ perceptions of the interviewer's knowledge, and in Experiment 2 (N=60), the participants’ perceptions of the interviewer's knowledge gaps. We found that participants in the just start condition (a) believed the interviewer had more knowledge (Experiment 1), and (b) searched less actively for gaps in the interviewer's knowledge (Experiment 2), compared to the traditional condition. We will discuss the current findings and how sources test and perceive the knowledge his or her interviewer possesses within a framework of social hypothesis testing (AU)

La técnica de Scharff se utiliza para extraer información de fuentes humanas. En el meollo de la técnica está la táctica de la «ilusión de saberlo todo», que apunta a engordar la percepción de una fuente sobre cuánto conocimiento posee un entrevistador sobre el hecho que se aborda. Para realizar este estudio cartografiamos los efectos derivados de la introducción de esta táctica particular, un método tradicional de aplicación, en el que el entrevistador afirma de modo explícito que ya conoce casi toda la información importante (la condición tradicional) y una manera nueva de implementación, en la que el entrevistador empieza a presentar la información que posee (la condición de simplemente iniciar la condición). Se comparó ambas versiones en dos experimentos distintos. En el experimento 1 (N=60) medimos la percepción que tenían los participantes de los conocimientos del entrevistador y en el experimento 2 (N=60) la percepción que tenían los participantes de las lagunas de conocimiento del entrevistador. Se halló que los participantes de la condición de «simplemente iniciar» (a) creían que el entrevistador poseía más conocimientos (experimento 1) y (b) buscaban de un modo menos activo las lagunas de conocimiento del entrevistador (experimento 2), en comparación con la condición «tradicional». Comentaremos estos resultados y cómo perciben y ponen a prueba las fuentes los conocimientos de su entrevistador, en el marco de la prueba de hipótesis social (AU)

Statements about true and false intentions: using the Cognitive Interview to magnify the differences.

This study investigates the combined effect of the Cognitive Interview (CI) and the unanticipated questions approach on the magnitude of the elicited cues to true and false intentions. The participants (N = 125) planned for either a mock crime or a non-criminal event, half of them were interviewed with a standard interview (SI) and half with the CI. All participants were asked one set of questions targeting their intentions (anticipated questions) and one set of questions targeting the phase in which they planned their stated intentions (unanticipated questions). As predicted, the questions about the planning phase were perceived as unanticipated by both liars and truth-tellers. Furthermore, and as predicted, the truth-tellers' (vs. the liars') answers to the unanticipated questions were significantly more detailed. Importantly, and in line with our predictions, for the answers given to questions about the planning-phase, liars and truth-tellers differed more clearly in the CI-condition than in the SI-condition, indicating that the CI indeed magnified the differences between liars and truth-tellers. In addition, and as predicted, the truth-tellers' (vs. the liars') descriptions of their intentions were more characterized by information related to how to attain the stated goal.

Interviewing strategically to elicit admissions from guilty suspects.

In this article we introduce a novel interviewing tactic to elicit admissions from guilty suspects. By influencing the suspects' perception of the amount of evidence the interviewer holds against them, we aimed to shift the suspects' counterinterrogation strategies from less to more forthcoming. The proposed tactic (SUE-Confrontation) is a development of the Strategic Use of Evidence (SUE) framework and aims to affect the suspects' perception by confronting them with statement-evidence inconsistencies. Participants (N = 90) were asked to perform several mock criminal tasks before being interviewed using 1 of 3 interview techniques: (a) SUE-Confrontation, (b) Early Disclosure of Evidence, or (c) No Disclosure of Evidence. As predicted, the SUE-Confrontation interview generated more statement-evidence inconsistencies from suspects than the Early Disclosure interview. Importantly, suspects in the SUE-Confrontation condition (vs. Early and No disclosure conditions) admitted more self-incriminating information and also perceived the interviewer to have had more information about the critical phase of the crime (the phase where the interviewer lacked evidence). The findings show the adaptability of the SUE-technique and how it may be used as a tool for eliciting admissions.
