Developing a scale to measure the presence of possible prejudicial stereotyping in police interviews with suspects: The Minhas Investigative Interviewing Prejudicial Stereotyping Scale (MIIPSS)

If police interviewers’ hold negative feelings towards certain groups, this may affect how they interview them (either as victims, witnesses or suspects) in that they may not obtain reliable accounts, being the aim of such interviews. The Minhas Investigative Interviewing Prejudicial Stereotyping Scale (MIIPSS) has been developed to assess the level of any investigative interviewers’ prejudicial stereotyping towards suspects. The current exploratory study involved semi-structured interviews with twenty people, who had previously been interviewed as suspects in England and also eight very experienced lawyers. Both their views were measured using the MIIPSS before being subjected to a Guttman analysis. Statistical analyses showed that MIIPSS satisfies the criteria for classification as a valid unidimensional and cumulative scale. Therefore, researchers could use MIIPSS as a tool to measure prejudicial stereotyping in investigative interviews. Interviewers could also use MIIPSS to monitor their own attitudes towards certain groups or individuals suspected of different types of crimes.     

Development of an information sheet providing rapport advice for interpreters in police interviews

Abstract

The present paper reports the development of an information sheet designed to aid interpreters in police interviews in recognizing, conveying and inadvertently obstructing rapport-building efforts by police interviewers. The contents of this sheet were informed by past research defining rapport, and rapport uses in police interviews. We used a mixed experimental design to test the information sheet. One group (Intervention, n = 35) was randomly assigned to read an information sheet before responding to short vignettes of police interviewing foreign non-English speaking suspects about international crimes, while another (Control) group (n = 37) simply responded to the vignettes. Perceptions of rapport cues by the intervention group exceeded that of the control group. However, the groups performed equally well at identifying appropriate methods to convey/avoid obstructing rapport. Feedback from the intervention group on the helpfulness of the information sheet was largely positive. The findings were used to improve the information sheet which can be used to alert interpreters to the importance of rapport in suspect interviews.     

Comparing the effects of explicit and implicit false-evidence ploys on Mock Jurors' verdicts,sentencing recommendations,and perceptions of police interrogation

In police interrogation, an explicit false claim to have evidence raises important legal and constitutional questions. Therefore, some interrogation manuals recommend implicit false-evidence ploys (FEP) that ask suspects about potential evidence without making a direct claim to possess the evidence. Similar to the hypotheses in a recent study of implicit FEP and confession rates, we hypothesized that individuals would perceive implicit FEP as less coercive and deceptive when compared to explicit FEP that involve direct claims of false evidence. Although mock jurors rated all FEP as highly deceptive and coercive and as more deceptive than controls, we found that participants did not view implicit and explicit FEP differently and that ploy specificity (implicit or explicit) failed to affect verdicts or recommended sentences. These findings suggest that although interrogation trainers and scholars in law and psychology discriminate between the methods, jurors do not.     

Police interviewing styles and confessions in Japan

Psychological studies of suspects' confessions have been conducted mostly in English-speaking and European countries, and the results may not generalise to countries whose cultures and policing practices differ. In particular, the difference between Japanese and Western laws may affect the roles that police interviewers play in suspects' confessions. This study examined the interviewing techniques used by Japanese police officers and associated features of the suspects' confessions. An extensive questionnaire was completed by 276 police officers across Japan. Detailed ratings of their interview techniques were factor analysed, yielding five factors: Presentation of Evidence, Confrontation, Rapport Building, Active Listening, and Discussion of the Crime. Based on these five factors, we identified four interviewing styles: Evidence-focused, Confrontational, Relationship-focused, and Undifferentiated. When interrogators employed the Relationship-focused interviewing style, suspects were more likely to make full confessions and to provide new information. By contrast, suspects were more likely to make partial confessions and were less cooperative when the police officers employed an Evidence-focused style.     

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.

Urgent issues and prospects at the intersection of culture,memory, and witness interviews: Exploring the challenges for research and practice

The pursuit of justice increasingly relies on productive interactions between witnesses and investigators from diverse cultural backgrounds during investigative interviews. To date, the role of cultural context has largely been ignored by researchers in the field of investigative interviewing, despite repeated requests from practitioners and policymakers for evidence-based guidance for the conduct of interviews with people from different cultures. Through examining cultural differences in human memory and communication and considering specific contextual challenges for investigative interviewing through the lens of culture, this review and associated commentaries highlight the scope for considering culture and human diversity in research on, and the practice of, investigative interviewing with victims, witnesses, and other sources. Across 11 commentaries, contributors highlight the importance of considering the role of culture in different investigative interviewing practices (e.g., rapport building, questioning techniques) and contexts (e.g., gender-based violence, asylum seeking, child abuse), address common areas of cultural mismatch between interviewer–interviewee expectations, and identify critical future routes for research. We call for an increased focus in the investigative interviewing literature on the nature and needs of our global community and encourage constructive and collaborative discussion between researchers and practitioners from around the world to better identify specific challenges and work together towards evidence-based solutions.     

Detecting truth in suspect interviews: the effect of use of evidence (early and gradual) and time delay on Criteria-Based Content Analysis,Reality Monitoring and inconsistency within suspect statements

The strategic use of evidence in interviews with suspects has been shown to increase the ability of interviewers to accurately and consistently distinguish truthful from deceptive accounts. The present study considers the effect of early and gradual revelation of evidence by the interviewer, and the effect of shorter and longer delay on the verbal quality of truth-teller and liar statements within a mock crime paradigm. It was hypothesised that gradual disclosure of evidence (1) in terms of inconsistencies (a) within statements and (b) between statements and such evidence and (2) of the criteria of Criteria-Based Content Analysis (CBCA) and of Reality Monitoring (RM) would emphasise differences in the verbal quality of truth-teller and liar statements. Forty-two high school students took part in the study. The use of statement-evidence and within-statement inconsistency appears to be a robust cue to deception across interview style and delay. This indicates that gradual disclosure in interviews may increase interviewer accuracy in veracity decisions by eliciting statement inconsistencies. However, gradual revelation and delay affected the ability of CBCA and RM criteria to distinguish the veracity of suspect statements.     

Differences in personality and mental state between suspects and witnesses immediately after being interviewed by the police

Abstract

There is increased recognition that people interviewed by the police are often psychologically vulnerable due to modest intelligence, mental health problems, disturbed mental state, and personality problems. The current study aimed to investigate differences in the mental state and personality between suspects and witnesses. The participants were 78 individuals (47 suspects and 31 witnesses) who had been interviewed by the Icelandic police. They were assessed psychologically immediately after the interview with the police was completed. Significant differences emerged between the two groups with the suspects being more depressed, hopeless, compliant and personality disordered than the witnesses. Four of the suspects claimed to have made a false confession to the police due to their immediate need or psychological problems.     

Securing reliable information in investigative interviews: coercive and noncoercive strategies preceding turning points

ABSTRACT

Investigative interviewers apply a range of physical, cognitive, social or legalistic strategies to secure information from suspects. The perceived effectiveness of coercive and noncoercive strategies on turning points was examined by interviewing 34 practitioners and 30 high value detainees in East Asian and Western jurisdictions. Each recounted an interview with an initially uncooperative detainee who became cooperative, or an initially cooperative detainee who became resistant or silent. Analyses of interview narratives identified perceived turning points in the practitioner-suspect relationship associated with clear outcomes. Independent of jurisdiction, 56% of the noncoercive strategies were associated with cooperation, yielding reliable information in 49.4% and true admissions in 20.0% of the cases. In contrast, coercive strategies were perceived as more ineffective (58.9%) than effective (14.6%) in securing information. Physical coercion, intimidation and deception were most frequently acknowledged to yield false information. These findings suggested prioritisation of noncoercive social and physical interview strategies and international consensus on best practices.     

Urgent issues and prospects in reforming interrogation practices in the United States and Canada

The current article presents a series of commentaries on urgent issues and prospects in reforming interrogation practices in Canada and the United States. Researchers and practitioners, who have devoted much of their careers to the field of police and intelligence interrogations, were asked to provide their insights on an area of interrogation research that they believe requires immediate attention. The submitted independent commentaries covered a variety of topics – from police recruitment, interrogation training, use of proper interrogation practices, and the treatment of confession evidence in court. Common concerns from the contributions pertained to the lag between scientific knowledge on interrogations and the application of such knowledge in the justice system, and the glaring disparity between the treatment of similar issues in the interrogation context versus other criminal justice contexts. A primary intent of this collection of commentaries is to serve as a resource pointing researchers in the direction of the fundamental areas that require immediate consideration and encouraging them to simultaneously pursue solutions to the overarching concerns that emerged from this project.     

Individual differences in interrogative suggestibility: life adversity and field dependence

Since the turn of the century much research has explored the concept of interrogative suggestibility, with recent research highlighting a sizeable link between the reported experience of negative life events (NLEs) and performance on the Gudjonsson Suggestibility Scale 1 (GSS1). The present study sought to reinvestigate the previously found novel relationship, as well as explore the role of field dependence as a possible coping mechanism implemented during interview by such vulnerable interviewees. As expected, highly significant correlations between NLEs and the suggestibility components of the GSS emerged. Field dependence, however, failed to correlate significantly with either NLE or GSS scores. Nonetheless, some additional findings relating to age, NLEs, and shift scores on the GSS were noted, which may help further our understanding of the NLE to interrogative suggestibility relationship. A new group of vulnerable interviewees, who are as yet unrecognized by the police or courts, has also been identified.     

口供何以中心——“罪从供定”传统及其文化解读

从制度到实践,口供在古代刑事司法中的作用被强调到无以复加的程度:赃证仅仅是获取和推核口供的辅助手段,孤供可以定罪,而无供情况下则通常只能办成悬案或疑案。相应的,作为取供中的合法暴行,最不可妄加的拷掠成了断狱中最不能离开的审讯手段。而有限的可知论、伦理秩序和狱无淹滞的价值诉求、反逻辑的自由心证及非对抗的刑事司法等则为口供主义提供了坚实的文化支撑。     

Feeling guilty to remain innocent: the moderating effect of sex on guilt responses to rule-violating behavior in adolescent legal socialization

Legal socialization researchers have ignored the role of emotions such as guilt to explain rule-violating behavior (RVB). The purpose of Study 1 was to determine if anticipated guilt or guilt proneness was a better predictor of RVB. Participants were 325 university students who completed an online questionnaire. Correlations indicated that both measures were related significantly to RVB; however, when both were entered into a multiple regression as predictors, only anticipated guilt was significant. This suggested that anticipated guilt was a stronger predictor of RVB than guilt proneness. The purpose of Study 2 was to investigate the effects of anticipated guilt on future RVB while controlling for the integrated legal socialization variables. Participants were 283 middle school and 187 high school students. Multiple regression analyses were conducted to predict students' future engagement in RVB. Anticipated guilt predicted RVB for middle school and high school students. However, sex moderated these effects. Male students low in anticipated guilt committed more RVBs than male students high in guilt. Female high school students showed a similar effect but not at the same magnitude as the male students. Guilt had no significant effect on RVB for female middle school students. Implications for the findings are discussed.     

Problems in expert deception detection and the risk of false confessions: no proof to the contrary in Levine et al. (2014)

Lie-detection research has shown that observers who rely on nonverbal cues or on verbal cues correctly classify on average 54% of truth tellers and liars. In addition, over the years, countless numbers of innocent people have made false confessions and, in analysing the problem, researchers have implicated both a suspect's vulnerability and the persuasive influence of certain police interrogation tactics. Levine et al. (2014) aim to contribute to these vast bodies of literature by reporting two studies purportedly showing that expert interviewers – when they are permitted to question interviewees – can achieve almost perfect accuracy without eliciting false confessions. We argue that theoretical and methodological aspects of these studies undermine the reliability and validity of the data reported, that as a result the studies do not contribute to the scientific literatures on lie detection and false confessions in any meaningful way, and that the results are dangerously misleading.     

Assessing the effectiveness and efficiency of a police service: the analytics of operational reviews

Concerns over rising costs have forced police services to balance increasing fiscal and operational pressures. Discussions of the resources and requirements of police, however, are generally only informed by political expediency and traditional practice. Operational reviews (ORs) can be used to document the demands on police, their capacity to respond, and ways in which they can become more efficient and effective. Drawing on an OR of a major urban Canadian police service, this article provides a broad outline of the components of an OR and the analytics that can be used to answer these key questions.     

“Drop the clipboard and help me!”: The determinants of observer behavior in police encounters with suspects

Much of the knowledge about police behavior on the streets is based on observational research. Little research, however, had examined the impact of reactivity in police observational data. One theme in the field research literature was that observer behavior could act as a source of bias in observational data. This article uses data from a large-scale observational study of police to predict this form of reactivity during encounters with suspects. In other words, “Are observer effects triggered by situational factors (i.e., dangerous suspects or situations) or a function of observer characteristics?” Results from a two-level hierarchical logistic model indicated that observers with higher academic rank (e.g., advanced graduate students), lower grade point averages, and more conservative attitudes toward criminality were less likely to get involved in police work during encounters with suspects. The implications of these findings for recruiting and training police researchers are discussed.     

Reporting of crime to the police in the Federal Republic of Germany: A comparison of the old and the new lands

A victimization survey of 7,026 households in the former east and west German Länder (states) carried out one year after the unification of Germany presented a unique opportunity to examine factors associated with the reporting of crime to the police. Logistic regression was used to identify factors associated with variation in the dependent variable, reporting of crime to the police, controlling for victimizations which occurred prior to and subsequent to unification, as well as whether the victim resided in the former east or west German Länder. The amount of loss in German Marks or seriousness of physical injury were the principle determinants of whether a crime was reported to the police.
