Examination of the consistency of interviewer performance across three distinct interview contexts

Abstract

The current study examined the consistency of investigative interviewers' performance (n=31) across three distinct interview paradigms: (a) a mock interview where an adult actor played the role of a child recalling abuse, (b) a mock interview where a school child recalled an innocuous event that was staged at the child's school, and (c) a field interview where the interviewer elicited a statement of abuse from a child. Performance was measured by calculating the proportion of open-ended and leading questions, and by eliciting expert ratings of the presence of a range of problem behaviours commonly exhibited by interviewers. Overall, the performance of individual interviewers was relatively stable across the tasks. Heterogeneity in stability, however, differed according to the type of question and the nature of the event being examined. In particular, the mock interview paradigm where the adult acted the role of an alleged child abuse victim produced a measure of performance that was more similar to the field interview than the interview where a school child recalled an innocuous event. The implications of the findings for trainers, and directions for future research, are discussed.     

Can order of general and specific memory prompts help children to recall an instance of a repeated event that was different from the others?

Does asking about the general event before asking about a specific instance help children to report details of a particular instance of a repeated event that was different from the others? Six- to eight-year-old children either experienced or heard stories about a magic show. An equal number of children had one, four, or six similar experiences. One week later, half of the children were asked to describe what happens during the magic shows and then what happened during the target experience and half were asked what happened followed by what happens. Following free recall, all children were asked cued recall questions about the target instance. Memory reports were more complete when the general prompt was administered first than when it was administered second. Implications for the forensic interviewing of children who allege repeated abuse are discussed.     

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.     

Who should I look at? Eye contact during collective interviewing as a cue to deceit

Pairs of liars and pairs of truth tellers were interviewed and the amount of eye contact they made with the interviewer and each other was coded. Given that liars take their credibility less for granted than truth tellers, we expected liars to monitor the interviewer to see whether they were being believed, and to try harder to convince the interviewer that they were telling the truth. It was hypothesised that this monitoring would manifest itself through more eye contact with the interviewer and less eye contact with each other than in the case of truth tellers. A total of 43 pairs of participants took part in the experiment. Truth tellers had lunch in a nearby restaurant. Liars took some money from a purse, and were asked to pretend that instead of taking the money, they had been to a nearby restaurant together for lunch. Pairs of liars looked less at each other and displayed more eye contact with the interviewer than pairs of truth tellers. The implications of these findings are discussed.     

Are you talking to me? Influencing behaviour and culture in police interviews

Abstract

This study examines the relationship between two types of influencing behaviour in police interviews (being kind and rational persuasion) and three types of interview effectiveness, i.e. the suspects’ willingness to give a statement, their estimation of the quality of the relationship with the detective, and suspects’ admission. We expected that being kind and rational persuasion (arguments referring to logic and rationality) would have a different effect on suspects from cultures that tend to be direct and content-oriented (low-context cultures) versus cultures in which communication is more indirect and context orientated (high-context cultures). To examine this, experienced police detectives interviewed mock theft suspects from low-context (n=25) and high-context (n=27) cultures. As predicted, and particularly for high-context suspects, being kind in terms of rewarding and offering was positively related to the perceived quality of the relationship of the suspect, while being kind in terms of active listening behaviour was positively related to admissions. Furthermore, and as expected, there was a positive relationship between rational persuasion of the police detective and admissions for low-context suspects, but also a negative relationship between rational persuasion and admissions for high-context suspects.     

Developing Strategies for Asking Questions in Negotiation

Although negotiation writers often advise negotiators to have a strategy for asking their counterparts questions, the negotiation literature does not currently provide a detailed discussion of how to develop a strategy for asking questions in negotiation. This essay begins that discussion. In doing so, it draws from such disciplines as logic, linguistics, and cognitive psychology, in which the act of questioning has been examined with the goal of developing theory. This article also draws from such applied disciplines as law, education, and journalism, in which questioning as a matter of strategy has also been examined. A common theme across these different domains has been potential resistance to answering questions on the part of the person being interviewed and explorations of the sources of that resistance. Therefore, in this discussion of questioning strategy, I have focused particularly on how resistance can be avoided or overcome.     

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.     

The occurrence of eye blinks during a guilty knowledge test

Abstract

In the present experiment we examined whether eye blinks could discriminate between guilty and innocent examinees in a Guilty Knowledge Test (GKT). Based on the assumption that guilty examinees would experience more cognitive load when responding to the key items than to the control items, we hypothesized that they would display fewer eye blinks during the key items than during the control items. For innocent examinees, responding to the key and control items should be equally demanding, and no differences in eye blinks between key and control items were expected. A total of 26 participants took part in an experiment where 13 guilty examinees committed a mock theft (of an exam paper) and the remaining 13 innocent examinees went on with their normal business. All participants underwent a GKT whereby their eye blinks were measured. Both guilty and innocent examinees displayed the pattern of eye blinks that we predicted. The implications of the findings are discussed.
