On the psychology of confessions: does innocence put innocents at risk?

The perceived guilt and innocence of adults with developmental language disorder and adults with typical language during a mock interrogation

PURPOSE

This study examined if there were differences in the guilty and not guilty judgments of adults with developmental language disorder (DLD) and those with typical language (TL) functioning.

METHOD

Twenty-four adults (12 DLD, 12 TL) were assigned to either the guilty or not guilty conditions. Those in the guilty condition engaged in a mock crime while those in the not guilty condition were informed that a crime had been committed. Peer jurors were presented with video interrogations of the DLD (6 guilty, 6 not guilty) and TL (6 guilty, 6 not guilty) participants and were asked to make categorical judgments of guilty and not guilty and to indicate confidence in their judgments.

RESULTS

In general, peer jurors were not accurate in their judgments of the accused, and were more likely to judge individuals with DLD as guilty relative to accused individuals with TL. Peer jurors were particularly poor at judging innocent adults with DLD as not guilty and guilty adults with TL as guilty. Despite this, peer jurors were more confident than not in their guilty and not guilty determinations.

CONCLUSIONS

Peer jurors are confident in their judgments of the guilt of the accused when they should not be, particularly in the case of accused adults with DLD. Implications are discussed.

The "Partial Innocence" Effect: False Guilty Pleas to Partially Unethical Behaviors

Although research has focused on the "innocence problem," "partial innocence" may also plague individuals who plead guilty to crimes they did not commit, but that are either comparable, more severe, or less severe than their actual crimes. Using a high-stake experimental paradigm and an immersive role-playing paradigm, we examined the psychology of partial innocence. Students were randomly induced (or imagined themselves) to be innocent, guilty, or partially innocent of committing an academic transgression and then given the choice to accept or reject a deal to avoid disciplinary sanction. Across three studies (Ns = 88, 75, 746), partially innocent students pled to cheating nearly as often as guilty students and vastly more often than innocent students. Partially innocent students-not unlike guilty students-experienced greater feelings of guilt than did innocent students. In turn, these feelings of guilt, but not shame, were associated with taking responsibility for a range of transgressions not committed.

From criminal interrogations to investigative interviews: a bibliometric study

This paper presents the results of a bibliometric study providing a comprehensive overview of the social science research conducted on criminal interrogations and investigative interviews since the 1900s. The objectives are to help researchers to further understand the research field, to better communicate research findings to practitioners, to help practitioners understand the breadth of scientific knowledge on criminal interrogations and investigative interviews, and to foster dialog between researchers and practitioners. To begin, after a brief description of Web of Science, we describe how we developed our database on criminal interrogations and investigative interviews. Then, we report the yearly evolution of articles, the journals where they were published, the research areas covered by this research field, as well as the authors, the institutions and the countries that published the most on a variety of topics related to criminal interrogations and investigative interviews. Finally, we present the most used keywords and the most cited articles, and examine the research on questionable tactics and techniques in the research field of criminal interrogations and investigative interviews. This paper ends with a critical look at the results, for the benefit of researchers and practitioners interested in criminal interrogations and investigative interviews.

Articulating guilt? The influence of guilt presumption on interviewer and interviewee behaviour

Research has repeatedly shown that accusatory questions posed during an investigative interview are indicative of biased beliefs about suspect guilt. Linguistic research has shown that the verbs used in utterances can be indicative of biased beliefs about another person. In the present study we examined question type and the verbs used in question formulation using non-police participants to explore the influence of guilt presumption on interview questions. In Study1 we used the Linguistic Category Model (LCM; Semin and Fiedler European Review of Social Psychology, 2, 1–30, 1991) and in Study 2, the Question-Answer Paradigm (QAP; Semin et al. Personality and Social Psychology Bulletin, 21, 834–841, 1995) to analyse verb abstraction and positive/ negative valence of the formulated interview questions. We also explored whether interviewers’ guilt presumptions changed over the course of the interview as well as their motivations for creating the questions they chose to ask (Study 2). We found that participants who presumed guilt were more likely to formulate accusatory questions and use a higher verb abstraction with negative valence (Study 1 and 2). Interviewers asked more questions to gather additional information overall; however, the number of questions was negligible for trying to find support for alternative scenarios or to falsify existing guilt beliefs (Study 2). Interviewers who presumed guilt were also less likely to change their views during the interview and were more likely to report using behavioural cues to solidify their guilt presumptions (Study 2). The overall findings are in line with previous research in both guilt presumptive interviewing and linguistically biased language; however, we expanded on previous research by allowing participants to come to their own conclusions regarding guilt, as well as formulating their own questions for the suspect. Finally, we conclude that there are extensive limitations for using the LCM in applied interview settings and these are discussed.

Detecting Lies is a Child (Robot)’s Play: Gaze-Based Lie Detection in HRI

Robots destined to tasks like teaching or caregiving have to build a long-lasting social rapport with their human partners. This requires, from the robot side, to be capable of assessing whether the partner is trustworthy. To this aim a robot should be able to assess whether someone is lying or not, while preserving the pleasantness of the social interaction. We present an approach to promptly detect lies based on the pupil dilation, as intrinsic marker of the lie-associated cognitive load that can be applied in an ecological human–robot interaction, autonomously led by a robot. We demonstrated the validity of the approach with an experiment, in which the iCub humanoid robot engages the human partner by playing the role of a magician in a card game and detects in real-time the partner deceptive behavior. On top of that, we show how the robot can leverage on the gained knowledge about the deceptive behavior of each human partner, to better detect subsequent lies of that individual. Also, we explore whether machine learning models could improve lie detection performances for both known individuals (within-participants) over multiple interaction with the same partner, and with novel partners (between-participant). The proposed setup, interaction and models enable iCub to understand when its partners are lying, which is a fundamental skill for evaluating their trustworthiness and hence improving social human–robot interaction.

How downplaying or exaggerating crime severity in a confession affects perceived guilt

This study investigates how judgments of guilt are influenced by factual errors in confessions that either amplify or downplay the severity of the crime. Participants read a confession statement and police report in which either the confession was consistent with the police report, the suspect admitted to a worse crime or the suspect admitted to a lesser crime. Mediation analyses showed that, compared to consistent confessions, both types of directional errors reduced judgments of guilt. Inconsistencies that made the suspect look better - but not those that made the suspect look worse -also increased judgments of guilt via a direct effect. Confessions that contain errors that appear to exaggerate the severity of the crime prompt no higher judgments of suspect guilt; however, errors in confessions that are perceived to downplay the severity of the crime can prompt an increased perception of suspect guilt compared to a consistent confession.

Unraveling the Misconception About Deception and Nervous Behavior

In this article, we attempt to unravel the misconception about deception and nervous behavior. First we will cite research demonstrating that observers believe lie tellers display more nervous behaviors than truth tellers; that observers pay attention to nervous behaviors when they attempt to detect deception; and that lie tellers actually feel more nervous than truth tellers. This is all in alignment with a lie detection approach based on spotting nervous behaviors. We then will argue that the next, vital, step is missing: Research has found that lie tellers generally do not display more than truth tellers the nervous behaviors laypersons and professionals appear to focus on. If observers pay attention to nervous behaviors but lie tellers do not come across as being nervous, lie detection performance is expected to be poor. Research has supported this claim. We finally discuss ideas for research into lie detection based on non-verbal behaviors.

Neural correlates of anxiety under interrogation in guilt or innocence contexts

Interrogation elicits anxiety in individuals under scrutiny regardless of their innocence, and thus, anxious responses to interrogation should be differentiated from deceptive behavior in practical lie detection settings. Despite its importance, not many empirical studies have yet been done to separate the effects of interrogation from the acts of lying or guilt state. The present fMRI study attempted to identify neural substrates of anxious responses under interrogation in either innocent or guilt contexts by developing a modified "Doubt" game. Participants in the guilt condition showed higher brain activations in the right central-executive network and bilateral basal ganglia. Regardless of the person's innocence, we observed higher activation of the salience, theory of mind and sensory-motor networks-areas associated with anxiety-related responses in the interrogative condition, compared to the waived conditions. We further explored two different types of anxious responses under interrogation-true detection anxiety in the guilty (true positive) and false detection anxiety in the innocent (false positive). Differential neural responses across these two conditions were captured at the caudate, thalamus, ventral anterior cingulate and ventromedial prefrontal cortex. We conclude that anxiety is a common neural response to interrogation, regardless of an individual's innocence, and that there are detectable differences in neural responses for true positive and false positive anxious responses under interrogation. The results of our study highlight a need to isolate complex cognitive processes involved in the deceptive acts from the emotional and regulatory responses to interrogation in lie detection schemes.

Cumulative Disadvantage: A Psychological Framework for Understanding How Innocence Can Lead to Confession, Wrongful Conviction, and Beyond

False confessions are a contributing factor in almost 30% of DNA exonerations in the United States. Similar problems have been documented all over the world. We present a novel framework to highlight the processes through which innocent people, once misidentified as suspects, experience cumulative disadvantages that culminate in pernicious consequences. The cumulative-disadvantage framework details how the innocent suspect's naivete and the interrogator's presumption of guilt trigger a process that can lead to false confession, the aftereffects of which spread to corrupt evidence gathering, bias forensic analysis, and virtually ensure wrongful convictions at trial or through pressured false guilty pleas. The framework integrates nascent research underscoring the enduring effects of the accumulated disadvantages postconviction and even after exoneration. We synthesize findings from psychological science, corroborating naturalistic evidence, and relevant legal precedents to explain how an innocent suspect's disadvantages can accumulate through the actions of law enforcement, forensic examiners, prosecutors, defense attorneys, judges, juries, and appeals courts. We conclude with prescribed research directions that can lead to empirically driven reforms to address the gestalt of the multistage process.

Can a Robot Catch You Lying? A Machine Learning System to Detect Lies During Interactions

Deception is a complex social skill present in human interactions. Many social professions such as teachers, therapists and law enforcement officers leverage on deception detection techniques to support their work activities. Robots with the ability to autonomously detect deception could provide an important aid to human-human and human-robot interactions. The objective of this work is to demonstrate the possibility to develop a lie detection system that could be implemented on robots. To this goal, we focus on human and human robot interaction to understand if there is a difference in the behavior of the participants when lying to a robot or to a human. Participants were shown short movies of robberies and then interrogated by a human and by a humanoid robot "detectives." According to the instructions, subjects provided veridical responses to half of the question and false replies to the other half. Behavioral variables such as eye movements, time to respond and eloquence were measured during the task, while personality traits were assessed before experiment initiation. Participant's behavior showed strong similarities during the interaction with the human and the humanoid. Moreover, the behavioral features were used to train and test a lie detection algorithm. The results show that the selected behavioral variables are valid markers of deception both in human-human and in human-robot interactions and could be exploited to effectively enable robots to detect lies.

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.

Fuzzy-Trace Theory, False Memory, and the Law

Fuzzy-trace theory (FTT) provides well-researched scientific principles that explain worrisome forms of false memory in the law. False memories are of great legal concern because memory reports are frequently the evidence that determines guilt/innocence and are sometimes the only evidence that crimes have been committed. FTT’s principles reveal errors in commonsense theories that jurors use to judge the credibility of witnesses’ memory reports. This science versus commonsense disconnect is salient in cases involving child witnesses, eyewitness identifications, and confessions. The consequences of this disconnect for justice could be ameliorated by a simple change in federal rules of evidence.

Interview expectancies: awareness of potential biases influences behaviour in interviewees

Expectancy effects are known to influence behaviour so that what is expected appears to be true. In this study, expectancy was induced using (fabricated) information about honesty and specific group membership. Targets were tested in a non-accusatory interview environment using neutral and information-gathering questions. It was hypothesized that those exposed to the negative information (the expectancy) would demonstrate behaviour consistent with an increased cognitive load, and evidence was found to support this prediction. Due to the investigative nature of the information-gathering questions, it was also expected that the targets exposed to the expectancy would exhibit more of these behaviours in the investigative portion of the interview. Some behaviour was found to support this prediction (i.e. shorter responses and increased speech disturbances); however, indicators of performance altering load were not observed during this phase of the interview. These findings support the hypothesis that expectancy effects can noticeably alter interviewee behaviour.

Confessions and Denials When Guilty and Innocent: Forensic Patients' Self-Reported Behavior During Police Interviews

Several self-report studies together with analyses of exoneration cases suggest that suspects with mental disorder are especially prone to making false confessions. The present study asked 153 forensic patients in Germany about their behavior during suspect interviewing by the police. Self-reported ground truth of guilt and innocence was asked for, thereby taking into account that the risk of false confession is present only if a person has ever been interviewed when innocent. Indeed, surveying samples that include suspects who have never been interviewed when innocent may lead to underestimating the risk of false confessions. In the present study, all patients reported having been interviewed previously when guilty; and almost two-thirds (62%, n = 95), that they had also been interviewed at least once when innocent. These participants stated that they remained silent while being interviewed significantly more often when guilty (44%) compared to when innocent (15%). This corroborates laboratory research findings indicating that the right to remain silent is waived more often by innocent than by guilty suspects. Out of all 95 participants who were ever interviewed when innocent, 25% reported having made a false confession on at least one occasion. This result is in line with previous international research showing a high percentage of false confessions among suspects with mental disorder.

Challenges for Research into Military Investigations

In cases of suspected violations of rules, regulations or the law by armed forces personnel, investigations are invariably mandatory. Military investigations differ from well-researched civilian criminal investigations. Differing from civilian police detectives, most military investigators - as disciplinary supervisors and military police personnel - have a number of tasks to accomplish, which include leading in combat and ensuring military readiness. Military investigations can lead to substantive negative or positive consequences for military readiness, including mental health, unit cohesion and subjective legal certainty. This impact on unit cohesion and mental health is influenced by any prior history of distress or trauma; military investigations are often preceded by contravention of internal disciplinary acts, complaints and traumatic events. This study explores factors in the differing military and legal systems of Germany and the United Kingdom (UK) that might help military personnel to successfully conduct investigations while ensuring deployment readiness and maintaining human rights.

T-Pattern Analysis and Cognitive Load Manipulation to Detect Low-Stake Lies: An Exploratory Study

Deception has evolved to become a fundamental aspect of human interaction. Despite the prolonged efforts in many disciplines, there has been no definite finding of a univocally "deceptive" signal. This work proposes an approach to deception detection combining cognitive load manipulation and T-pattern methodology with the objective of: (a) testing the efficacy of dual task-procedure in enhancing differences between truth tellers and liars in a low-stakes situation; (b) exploring the efficacy of T-pattern methodology in discriminating truthful reports from deceitful ones in a low-stakes situation; (c) setting the experimental design and procedure for following research. We manipulated cognitive load to enhance differences between truth tellers and liars, because of the low-stakes lies involved in our experiment. We conducted an experimental study with a convenience sample of 40 students. We carried out a first analysis on the behaviors' frequencies coded through the observation software, using SPSS (22). The aim was to describe shape and characteristics of behavior's distributions and explore differences between groups. Datasets were then analyzed with Theme 6.0 software which detects repeated patterns (T-patterns) of coded events (non-verbal behaviors) that regularly or irregularly occur within a period of observation. A descriptive analysis on T-pattern frequencies was carried out to explore differences between groups. An in-depth analysis on more complex patterns was performed to get qualitative information on the behavior structure expressed by the participants. Results show that the dual-task procedure enhances differences observed between liars and truth tellers with T-pattern methodology; moreover, T-pattern detection reveals a higher variety and complexity of behavior in truth tellers than in liars. These findings support the combination of cognitive load manipulation and T-pattern methodology for deception detection in low-stakes situations, suggesting the testing of directional hypothesis on a larger probabilistic sample of population.

The prevalence of false confessions in experimental laboratory simulations: A meta-analysis

We assessed experimental false confession studies using a meta-analysis to evaluate the prevalence of false confessions across methodologies and several moderator variables. False confessions were more likely in typing task studies than in collaborative or individual cheating studies. In typing studies, speed of typing did not affect false confession rates, but placement of the forbidden key in locations that rendered errors less plausible lowered the false confession rates. False-evidence ploys increased the likelihood of false confessions. We explore implications for courts, expert witnesses, scholars, and police interrogators.

Psychological Perspectives on Interrogation

Proponents of “enhanced interrogation techniques” in the United States have claimed that such methods are necessary for obtaining information from uncooperative terrorism subjects. In the present article, we offer an informed, academic perspective on such claims. Psychological theory and research shows that harsh interrogation methods are ineffective. First, they are likely to increase resistance by the subject rather than facilitate cooperation. Second, the threatening and adversarial nature of harsh interrogation is often inimical to the goal of facilitating the retrieval of information from memory and therefore reduces the likelihood that a subject will provide reports that are extensive, detailed, and accurate. Third, harsh interrogation methods make lie detection difficult. Analyzing speech content and eliciting verifiable details are the most reliable cues to assessing credibility; however, to elicit such cues subjects must be encouraged to provide extensive narratives, something that does not occur in harsh interrogations. Evidence is accumulating for the effectiveness of rapport-based information-gathering approaches as an alternative to harsh interrogations. Such approaches promote cooperation, enhance recall of relevant and reliable information, and facilitate assessments of credibility. Given the available evidence that torture is ineffective, why might some laypersons, policymakers, and interrogation personnel support the use of torture? We conclude our review by offering a psychological perspective on this important question.

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).

The Killing of Kitty Genovese: What Else Does This Case Tell Us?

Well known in popular culture, the 1964 murder of Kitty Genovese in Queens, New York, became famous because not one of an alleged 38 bystanders called police until it was too late. Within psychology, this singular event inspired the study of bystander intervention. With the spotlight of history focused on Ms. Genovese and bystanders, other events, also profound for what they tell us about human social behavior, have escaped public notice. Based on archival records and current interviews, this article describes the three issues linked to Genovese. First, three false confessions, taken from two individuals, led to their wrongful convictions and imprisonment. One of these individuals was cited by the U.S. Supreme Court in Miranda v. Arizona (1966); the other individual is alive and well and wants to clear his name. Second, the narrative of the unresponsive bystander was initiated by police, not by journalists, in response to probing questions about one of these confessions. Finally, there is the ironic fact, which somehow has slipped through the cracks, that the killer of Genovese was ultimately captured as a result of the intervention of two bystanders.

False confessions

As illustrated by numerous cases in recent years, DNA exonerations of innocent individuals have cast a spotlight on the counterintuitive problem of false confessions. Studying the underlying psychology scientists have found that (1) innocent people are often targeted for interrogation because police make erroneous but confident judgments of deception; (2) certain interrogation techniques-namely, lengthy sessions, presentations of false evidence, and minimization themes that imply leniency-increase the risk that innocent people will confess; (3) certain individuals are particularly vulnerable to influence-notably, those with mental health problems or intellectual impairments, which render them overly compliant or suggestible, and children and adolescents, who exhibit 'immaturity of judgment'; (4) confession evidence is highly persuasive in court as a matter of common sense, increasing perceptions of guilt, even among judges and juries who see the confession as coerced, and even at times when the confession is contradicted by exculpatory information; (5) Miranda rights to silence and to counsel are not sufficiently protective, so proposals for reform have centered on the mandatory recording of interrogations, from start to finish, and a shift toward using investigative interviewing-a less confrontational, less deceptive means of questioning suspects.

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.

Miranda at 50

In 1966, the U.S. Supreme Court handed down a controversial ruling in Miranda v. Arizona, which required police to inform suspects, prior to custodial interrogation, of their constitutional rights to silence and to counsel. In commemoration of the 50th anniversary of Miranda, we present a psychological analysis of the Court’s ruling. We show how the Court’s assumption that the provisions of the Miranda ruling would enable suspects to make knowing, intelligent, and voluntary decisions regarding whether to invoke or waive their constitutional rights has not been borne out by scientific research. Hence, we argue that even well-adjusted, intelligent adults are at risk of succumbing to police pressure during custodial interrogation. We conclude with policy implications and directions for future Miranda research.

Overcoming Innocents' Naiveté: Pre-interrogation Decision-making Among Innocent Suspects

Suspects, especially innocent ones, are highly susceptible to waiving their interrogation rights. This research tested the ability of two strategies to overcome innocent suspects' willingness to waive their rights. One strategy was based on the social influence of scarcity (i.e., not constraining the pre-interrogation time limit). The other strategy focused on disrupting individuals' cognitive fluency during the decision-making process (i.e., violating their induced expectation of offering a waiver). Disrupting innocent individuals' cognitive fluency increased their willingness to invoke their rights and, notably, was not qualified by interactions with any other factors. However, scarcity did not influence individuals' pre-interrogation decision-making. Results also further established the association between innocent individuals' naïve mindset and their willingness to waive their rights - specifically, innocents' willingness to waive their rights increased with the strength of their just world beliefs. The theoretical and applied implications of these findings are discussed. The importance and benefit of reforming pre-interrogation protocols using fair and feasible strategies that would disrupt suspects' cognitive fluency are emphasized.

Fuzzy-Trace Theory and Lifespan Cognitive Development

Fuzzy-trace theory (FTT) emphasizes the use of core theoretical principles, such as the verbatim-gist distinction, to predict new findings about cognitive development that are counterintuitive from the perspective of other theories or of common-sense. To the extent that such predictions are confirmed, the range of phenomena that are explained expands without increasing the complexity of the theory's assumptions. We examine research on recent examples of such predictions during four epochs of cognitive development: childhood, adolescence, young adulthood, and late adulthood. During the first two, the featured predictions are surprising developmental reversals in false memory (childhood) and in risky decision making (adolescence). During young adulthood, FTT predicts that a retrieval operation that figures centrally in dual-process theories of memory, recollection, is bivariate rather than univariate. During the late adulthood, FTT identifies a retrieval operation, reconstruction, that has been omitted from current theories of normal memory declines in aging and pathological declines in dementia. The theory predicts that reconstruction is a major factor in such declines and that it is able to forecast future dementia.

Personality Correlates of the Self-Assessed Abilities to Tell and Detect Lies, Tell Truths, and Believe Others

The contribution of personality dimensions (the Big Five) to self-assessed communication abilities to tell and detect lies, tell truths, and believe others was examined. One hundred seventy-four undergraduate students completed the Big Five personality inventory (BFI) and evaluated their relative lie-telling, truth-telling, lie-detection and their ability to believe other peoples’ truths. Results indicated that Extraversion predicted enhanced lie-telling, truth-telling, and lie-detection abilities. Openness to experience predicted higher ratings of lie-telling and lie-detecting abilities, indicating that for curious people with intellectual skills and attentiveness to inner feelings, lie-related abilities are important. Agreeableness predicted high ratings of believing skills and low ratings of the remaining three skills, indicating that well-tempered people tend to believe others. Conscientiousness and Neuroticism were negatively associated with telling lies persuasively. This was explained by the need of conscientious people to be honest and by the low self-confidence and negative emotions of people who scored high on Neuroticism. Implications of the present results were discussed.

Stressing the person: legal and everyday person attributions under stress

When determining the cause of a person's behavior, perceivers often overweigh dispositional explanations and underweigh situational explanations, an error known as the Fundamental Attribution Error (FAE). The FAE occurs in part because dispositional explanations are relatively automatic, whereas considering the situation requires additional cognitive effort. Stress is known to impair the prefrontal cortex and executive functions important for the attribution process. We investigated if stress increases dispositional attributions in common place and legal situations. Experiencing a physiological stressor increased participants' cortisol, dispositional attributions of common everyday behaviors, and negative evaluations. When determining whether a crime was due to the defendant's disposition or the mitigating situation, self-reported stress correlated with increased dispositional judgments of defendant's behavior. These findings indicate that stress may make people more likely to commit the FAE and less favorable in their evaluations of others both in daily life and when making socially consequential judicial decisions.

"Yes, I have sometimes stolen bikes": blindness for norm-violating behaviors and implications for suspect interrogations

Across two experiments, we studied a phenomenon akin to choice blindness in the context of participants' accounts of their own history of norm-violating behaviors. In Experiment 1, N = 67 participants filled in an 18-item questionnaire about their history of norm-violating behaviors (QHNVB). Subsequently, they were questioned about four of their answers, two of which had covertly been manipulated by the experimenter. Of the 134 manipulations, 20 (14.9%) remained undetected concurrently and 13 were accepted in retrospect (9.7%). In Experiment 2 (N = 37), we inserted a one-week interval between questionnaire and interview. Twenty-seven (36.5%) of the 74 manipulations remained undetected concurrently and three were accepted in retrospect (8.1%). Data obtained in a four-week follow-up indicated that our manipulations may have long-term effects on participants' perception of their own history of norm-violating behaviors. Implications for the occurrence of false confessions during the course of an interrogation are discussed.

When do we believe experts? The power of the unorthodox view

This paper examines the extent to which orthodoxy (degree of typicality) and congruence (degree of similarity with own opinion) mediate the influence of expert advice on decision makers' judgments. Overall, 227 members of the public and 60 police officers completed an online questionnaire involving an investigation into a child sex offence. Participants were asked to first (i) formulate their own "profile" of a likely offender then (ii) estimate the guilt of two presented suspect descriptions (orthodox vs. unorthodox), and, following the presentation of an "expert's" profile that matched either the orthodox or the unorthodox suspect, (iii) re-evaluate their guilt judgments of the two suspects based on this new advice. Finally, (iv) the perceived similarity (congruence) between the participants' own and the expert profile was assessed. Results revealed two key findings. First, expert profiles that matched a suspect's description elevated perceptions of guilt in that suspect, whilst also, simultaneously, very significantly decreasing the perception of guilt of the alternative suspect. This suggests a powerful rejection and downward revision of the other suspect. Second, perceived similarity of the profile (to one's own profile) was only a significant factor in increasing guilt judgments when assigning guilt to the unorthodox (as opposed to orthodox) suspect. Comparisons of lay judgments with those of police officers revealed few significant differences in effects. The finding that advice is most influential when unorthodox and incongruent suggests that decision makers are more likely to reevaluate judgments when expert advice contributes novel information that contradicts their beliefs. The practical implications of these findings are discussed for profilers, police, and decision research in general.

The effect of question expectedness and experience on lying about intentions

In recent years researchers have started to focus on lying about intentions (Granhag, 2010). In the present experiment participants were interviewed about their forthcoming trip. We tested the hypothesis that liars (N=43) compared to truth tellers (N=43) would give fewer details to unexpected questions about planning, transportation and the core event, but an equal amount or more detail to expected questions about the purpose of the trip. We also tested the hypothesis that participants who had previously experienced the intention (i.e., they had made such a trip before) would give more detail than those who had never experienced the intended action. The unexpected question hypothesis was supported, whereas the previous experience effect only emerged in interactions. The benefit of using different types of questions for lie detection purposes is discussed.

Social indicators of deception

OBJECTIVE

This study addresses a practical homeland security issue of considerable current concern: In a situation in which the opportunity exists to question or interview concurrently two or more suspects, how does one determine truth or deception at a social level?

BACKGROUND

Recent world events have led to an increased emphasis on the capacity to detect deception, especially in military, security, and law enforcement settings. In many screening or checkpoint situations, the opportunity exists to question two or more suspects regarding their involvement in some activity, yet investigators know very little regarding characteristics of speech or behavior that are exhibited between two suspects that indicate truth or deception.

METHOD

We conducted an empirical study in which pairs of police officers and firefighters who had served together as partners took part. In the "truth" conditions, each dyad described a recent event in which they had actually taken part, and in the "deceptive" conditions, each dyad fabricated a story that did not take place. We expected that the officers in the truth-telling dyads would be able to draw on shared or transactive memory of the actual event they had participated in and would describe this event in a more interactive manner than would those in deceptive dyads.

RESULTS

Results indicated greater evidence of synchrony of behavior as well as more interactive behaviors, such as mutual gaze and speech transitions, in truthful dyads than in deceptive dyads.

CONCLUSION

This research provides a unique perspective on detecting deception in a social context, and the results have both theoretical and practical value.

APPLICATION

These results can inform training programs and refine strategies used by screeners in field settings.

A case of a false confession after an inadvertent hypnotic induction

This article presents the case of a highly hypnotizable 28-year-old man who gave a false confession under police interrogation following an unintended hypnotic induction, but who was exonerated years later on the basis of DNA evidence. The author proposes that assessment of possible high hypnotizability be conducted in instances of otherwise unsubstantiated confessions.
