Running head: DECEPTIVE RESPONSES Detecting Deceit Via Analyses of Verbal and Nonverbal Behavior in Children and Adults

Abstract This experiment examined children's and undergraduates' verbal and nonverbal deceptive behavior, and the extent to which their truths and lies could be correctly classified by paying attention to these responses. A total of 196 participants (aged 5-6, 10-11, 14-15, and undergraduates

The ‘appropriate adult’: what they do and what they should do in police interviews with mentally disordered suspects

Background: In almost all countries worldwide, the first point of contact with the criminal justice system is with the police. A large proportion of these individuals may have vulnerabilities, such as mental health difficulties. Given the complexities associated with vulnerable suspects, such interviews may be compromised, which could lead to a miscarriage of justice. In England and Wales, the Police and Criminal Evidence Act (PACE) 1984 and its accompanying Codes of Practice lay down requirements for interviewing vulnerable suspects and provide for attendance of ‘appropriate adults’ to support communication between police and the vulnerable suspect. To date, however, their role has been under-researched. Aims/Hypotheses: To explore the role of appropriate adults in police interviews and test the hypotheses first that appropriate adults more commonly remain passive during interview than expected from guidance and, secondly, that any interventions are more likely than not to follow examples in current guidance. Methods: Transcripts of police interviews conducted with suspects with possible mental disorder and an appropriate adult present (N = 27) were analysed using a specially developed coding framework. Results: Appropriate adults were significantly more likely to remain passive than to intervene, even when current guidance would suggest intervention. When they did intervene, however, such interventions were significantly more likely than not to follow from guidance and the vulnerable suspect’s needs. Conclusions/Implications for practice: In our sample, appropriate adults were not fulfilling their role as outlined in the Police and Criminal Evidence Act (PACE) 1984 and accompanying Codes of Practice, specifically, they appeared to know what to do but not when to do it. There is a heightened risk of a miscarriage of justice in such circumstances without improvements

One way or another? Criminal investigators' beliefs regarding the disclosure of evidence in interviews with suspects in England and Wales

The research base concerning interviews with suspects remains to be comprehensively developed. For example, the extant literature provides differing views regarding how best to undertake the important interview task of disclosing evidence. In the current study, using a self-report questionnaire, 224 investigators based in England and Wales were asked as to their own preferred methods. Most respondents advocated a gradual method of disclosing evidence, stating that this approach would better reveal inconsistencies and obtain a complete version of events (similar to the reasoning of those who preferred disclosing evidence later). Those who advocated revealing evidence early stated this approach would more likely elicit confessions. Several respondents would not commit to one single method, arguing that their chosen strategy was contextually dependent. The study’s findings suggest that it remains arguable as to whether there is one best approach to evidence disclosure and/or whether particular circumstances should influence interviewing strategies

Empathy in the field: Towards a taxonomy of empathic communication in information gathering interviews with suspected sex offenders

Research suggests that those suspected of sexual offending might be more willing to reveal informa- tion about their crimes if interviewers display empathic behaviour. However, the literature concerning investigative empathy is in its infancy, and so as yet is not well understood. This study explores empathy in a sample of real-life interviews conducted by police officers in England with suspected sex offen- ders. Using qualitative methodology, the presence and type of empathic verbal behaviours displayed was examined. Resulting categories were quantitatively analysed to investigate their occurrence overall, and across interviewer gender. We identified four distinct types of empathy, some of which were used sig- nificantly more often than others. Female interviewers displayed more empathic behaviour per se by a considerable margin

Police Strategies and Suspect Responses in Real-Life Serious Crime Interviews

This research focuses exclusively on real-life taped interviews with serious crime suspects and examines the strategies used and types of questions asked by police, and suspects’ responses to these. The information source was audio-tape-recorded interviews with 56 suspects. These recordings were obtained from 11 police services across England and Wales and were analysed using a specially designed coding frame. It was found that interviewers employed a range of strategies with presentation of evidence and challenge the most frequently observed. Closed questions were by far the most frequently used, and open questions, although less frequent, were found to occur more during the opening phases of the interviews. The frequency of ineffective question types (e.g. negative, repetitive, multiple) was low. A number of significant associations were observed between interviewer strategies and suspect responses. Rapport/empathy and open-type questions were associated with an increased likelihood of suspects admitting the offence whilst describing trauma, and negative questions were associated with a decreased likelihood

The Lawyer in the Dutch Interrogation Room: Influence on Police and Suspect

In many European countries, providing a suspect in custody with legal aid before the first police interrogation is a heavily debated issue. In this paper, we report on an exploratory study on the use of coercion by the police and the use of the right to silence by suspects in 70 Dutch homicide cases and their relation to prior consultation and presence of a lawyer. Analysis of the data indicates that there is a relation between the presence of a lawyer in the interrogation room and the way in which police interrogators use coercion. To gain insight into whether the police use coercion and how this is achieved, we looked at the extent to which the interrogators make use of certain interrogation techniques and how the interrogation techniques are used to exert coercion. We found that legal advice from a lawyer before and during the interrogation corresponds with suspects more often using their right to silence. It also appears that the police are inclined to use ‘hard coercion’ when confronted with a silent suspect. The research thus raises the question as to whether the presence of a lawyer is an adequate way to prevent false confessions. Copyright © 2012 John Wiley & Sons, Ltd

The Combined Effects of Questioning Technique and Interviewer Manner on False Confessions

Although it is known that interrogation tactics can elicit false confessions and interviewer manner may determine the outcome of an interview, the combined effects of questioning technique and interviewer manner on false confessions have not been examined empirically. Following a false accusation of theft, participants were interviewed in one of four questioning conditions (minimisation, repetitive questioning, leading questions, and nonleading questions) in which interviewers adopted a stern or friendly manner. Perceptions of pressure to confess and interviewer behaviours were measured. Significantly more false confessions were elicited using nonleading questions rather than repetitive questioning. More false confessions were elicited in the friendly interviewer condition than in the stern interviewer condition. Neither interviewer manner nor questioning technique had a significant effect on subjective ratings of pressure to confess. The finding that false confessions may be elicited in the absence of coercive tactics may have implications for informing best practices in investigative interviewing. © 2018 John Wiley & Sons, Ltd
