Applying Hierarchy of Expert Performance (HEP) to investigative interview evaluation: strengths, challenges and future directions.

The purpose of this paper is to systematically examine the research literature on the decision of expert interviewers within the theoretical framework of the Hierarchy of Expert Performance (HEP). After providing an overview of the HEP framework, existing research in the investigative interviewing at each of the eight levels of the HEP framework is reviewed. The results identify areas of strength in reliability between experts' observations (Level 2) and of weakness in reliability between experts' conclusions (Level 6). Biases in investigative interview experts' decision making is also revealed at biasability between expert conclusions (Level 8). Moreover, no published data are available in reliability within experts at the level of observations (Level 1) or conclusions (Level 5), biasability within or between expert observations (Level 3 and 4) and biasability within expert conclusions (Level 7). The findings highlight areas where future research and practical endeavour are much needed for the investigative interview.

Investigative empathy: a strength scale of empathy based on European police perspectives.

A growing body of research suggests that empathy plays a major role in establishing and maintaining rapport during police interviews. The benefits of rapport include not only increased cooperation from interviewees, but also gaining more accurate investigation-relevant information. However, there still is no universally agreed-upon definition and very little research on operationalizing empathy, especially within investigative interviewing. The present study analyzed police interviewers' self-reports regarding their (a) training and methods employed during interviews, (b) application of empathy in interviews, and (c) definitions/understanding of empathy. It was found that officers in all seven participating countries varied within each country in their use of accusatory or information-gathering interview styles. The majority of participants in each country claimed to employ empathy in their interviews with suspects, yet they varied regarding the definitions they provided. In no country was empathy defined as having aspects that may not be conducive to investigative interviewing.

A brief report on rape myth acceptance: differences between police officers, law students, and psychology students in the United Kingdom.

A common perception is that police officers hold very negative attitudes about rape victims. Therefore, the purpose of this article is to establish whether police officers do accept stereotypical rape myths at a higher level compared to members of other populations. There were 3 comparison samples, composed of police officers, law students, and psychology students, that completed the Illinois Rape Myth Acceptance scale. Male and female police officers accepted "she lied" myths at a higher level than the student samples. Student samples were found to accept 2 types of rape myths ("she asked for it" and "he didn't meant to") at a higher level compared to police officers. No significant differences were found in the other 4 subfactors. Therefore, the pattern of results suggests that police officers do not adhere to stereotypical myths about rape victims more than do other populations.

Archival analyses of eyewitness identification test outcomes: what can they tell us about eyewitness memory?

Several archival studies of eyewitness identification have been conducted, but the results have been inconsistent and contradictory. We identify some avoidable pitfalls that have been present in previous analyses and present new data that address these pitfalls. We explored associations among various estimator variables and lineup outcomes for 833 "real life" lineups, including 588 lineups in which corroborating evidence of the suspect's guilt existed. Suspect identifications were associated with exposure duration, viewing distance, and the age of the witness. Nonidentifications were associated with the number of perpetrators. We also consider some of the inherent, unavoidable limitations with archival studies and consider what such studies can really tell researchers. We conclude that differences in sampling prohibit sensible comparisons between the results of laboratory and archival studies, and that the informational value of archival studies is actually rather limited.

Gender Differences in Theory of Mind, Empathic Understanding, and Moral Reasoning in an Offending and a Matched Non-Offending Population.

Previous research suggests that a lack of pro-social skills is characteristic of an offending personality. Two hundred male and female offenders and matched controls completed measures to assess: Theory of Mind, empathic understanding, and moral reasoning. Significant differences between the offenders and the control group, as well as between the male and female participants, were detected in theory of mind, empathic understanding and moral reasoning with offenders scoring lower than the control group, and with males scoring lower than females on most tests. The ability to assess Theory of Mind, empathic understanding, and moral reasoning, and subsequently to identify reduced ability, is not only useful for researchers but will also allow practitioners to tailor existing (or develop new) interventions specific to the needs of individuals. This could be particularly useful in terms of recidivism when applied to those involved in anti-social or offending behavior.

When the Evidence Is Incorrect: an Exploration of What Happens When Interviewers Unwittingly Present Inaccurate Information in Interviews with Suspects.

Skillfully presenting evidence/information to suspects is one of the few interviewing techniques that increases the likelihood of guilty suspects providing information or making a confession, without making innocent ones do so as well. It is important that this evidence/information is correct, since deliberately disclosing incorrect evidence poses some risks. Also, in real-life interviews, police interviewers may unwittingly disclose incorrect evidence, for example when a witness was mistaken and provided the police with incorrect information. The present study examined the behavior of fifty police interviewers in interviews with "suspects" of a scripted crime: what is their response when the interviewees try to explain to them that some of the evidence/information just disclosed by them is incorrect? Eleven interviewers responded adaptively (by actively picking up on this new information), 35 responded in a neutral way and four responded maladaptively (by discrediting the interviewee's claim). Experience and a full interview training had a significant negative relationship with adaptiveness. These results indicate that, when preparing and conducting interviews with suspects, greater awareness is needed of the possibility that some of the evidence/information that is to be disclosed could be incorrect, and therefore it is crucial that suspects' responses which suggest such may be the case are taken into account.

No Evidence Against Sketch Reinstatement of Context, Verbal Labels or the Use of Registered Intermediaries for Children with Autism Spectrum Disorder: Response to Henry et al. (2017).

Recently, Henry et al. (J Autism Dev Disord 8:2348-2362, 2017) found no evidence for the use of Verbal Labels, Sketch Reinstatement of Context and Registered Intermediaries by forensic practitioners when interviewing children with a diagnosis of autism spectrum disorder. We consider their claims, noting the limited ecological validity of the experimental paradigm, the impacts of repeated interviewing where retrieval support is not provided at first retrieval, question the interviewer/intermediary training and their population relevant experience, and comment on the suppression of population variances. We submit that rejecting these techniques on the basis of this study is completely unwarranted and potentially damaging, particularly if used in legal proceedings to undermine the value of testimony from children with ASD, who continually struggle to gain access to justice.

The development of a scale to discover outpatients' perceptions of the relative desirability of different elements of doctors' communication behaviours.

OBJECTIVE: The objective of the study was to discover which aspects of doctor communication behaviours are more or less desirable to patients who are attending medical outpatients clinics. METHODS: Two hundred and twenty patients took part in the study, which was undertaken in four phases. In phase one, patients completed a 10-item questionnaire where they indicated, by means of a five-point scale, their preferences for doctor communication behaviours. In phases two and three patients qualitatively expressed the meaning that they ascribed to terminology that is used by some researchers to define doctor communication behaviours. In the final phase of the study a 12-item questionnaire was developed by integrating the phase one questionnaire and patients' report from phases two and three. Patients indicated, by means of a five-point scale, their preferences for different communication behaviours that might be used by doctors. Patient's preferences were ranked in terms of the most to the least preferred behaviours. RESULTS: The findings suggest that patients most prefer consultations where doctors give information spontaneously and display affective behaviours. They least preferred consultations where medical matters are discussed and where information is not forthcoming. Furthermore, the finding suggests that the use of blanket terms by researches in defining doctor communication can lead to differences in interpretation by patients. CONCLUSIONS: The methods developed in the study appear to provide a useful tool to discover patients' desires in terms of doctor communication. PRACTICE IMPLICATIONS: The rank scale developed in the study could prove useful to medical practice. It could, for example, provide a straightforward method whereby doctors could readily access researcher's recommendations about communication. Furthermore, the scale could be used in various healthcare settings in order to discover if different patient groups vary in terms of the doctor communication they desire.

Detecting true lies: police officers' ability to detect suspects' lies.

Ninety-nine police officers, not identified in previous research as belonging to groups that are superior in lie detection, attempted to detect truths and lies told by suspects during their videotaped police interviews. Accuracy rates were higher than those typically found in deception research and reached levels similar to those obtained by specialized lie detectors in previous research. Accuracy was positively correlated with perceived experience in interviewing suspects and with mentioning cues to detecting deceit that relate to a suspect's story. Accuracy was negatively correlated with popular stereotypical cues such as gaze aversion and fidgeting. As in previous research, accuracy and confidence were not significantly correlated, but the level of confidence was dependent on whether officers judged actual truths or actual lies and on the method by which confidence was measured.

Exposure duration: effects on eyewitness accuracy and confidence.

The current study examined the relationship between the length of exposure to a face in an eyewitness setting and identification accuracy and confidence. A sample of 164 young (ages 17-25) and older (ages 59-81) adults viewed a simulated crime in which they saw the culprit's face for a short (12 s) or long (45 s) duration. They were then tested with a target absent (a line-up not containing the culprit) or target present line-up. Identification accuracy rates for both young and older participants were significantly higher under the long exposure condition. In the short exposure condition, witnesses who had made a correct identification of the target were more confident than incorrect witnesses. In the long exposure condition the confidence ratings of accurate and inaccurate witnesses did not differ. Discussion focuses on the extent to which extended exposure may inflate confidence judgments and variables that may moderate the relationship between exposure duration and face recognition accuracy.

Behavioural case linkage with solved and unsolved crimes.

Offender behaviour is used to distinguish between crimes committed by the same person (linked crimes) and crimes committed by different people (unlinked crimes) through behavioural case linkage. There is growing evidence to support the use of behavioural case linkage by investigative organisations such as the police, but this research is typically limited to samples of solved crime that do not reflect how this procedure is used in real life. The current paper extends previous research by testing the potential for behavioural case linkage in a sample containing both solved and unsolved crimes. Discrimination accuracy is examined across crime categories (e.g. a crime pair containing a car theft and a residential burglary), across crime types (e.g. a crime pair containing a residential burglary and a commercial burglary), and within crime types (e.g. a crime pair containing two residential burglaries) using the number of kilometres (intercrime distance) and the number of days (temporal proximity) between offences to distinguish between linked and unlinked crimes. The intercrime distance and/or the temporal proximity were able to achieve statistically significant levels of discrimination accuracy across crime categories, across crime types, and within crime types as measured by Receiver Operating Characteristic (ROC) analysis. This suggests that behavioural case linkage can be used to assist the investigation, detection and prosecution of prolific and versatile serial offenders.

Reducing misinformation effects in older adults with cognitive interview mnemonics.

We examined the effect of a prior Modified Cognitive Interview on young and older adults' recall of a short film of a staged crime and subsequent reporting of misinformation. Participants viewed the film followed the next day by misinformation presented in a postevent summary. They were then interviewed with either a Modified Cognitive Interview or a control interview followed by a recognition memory test. A Modified Cognitive Interview elicited more correct details and improved overall accuracy compared to a control interview in both age groups, although the young adults recollected three times more correct information in a Modified Cognitive Interview than the older adults. In both age groups, correct recollections of person and action details were higher in a Modified Cognitive Interview than a control interview. Importantly, older adults who were interviewed with a Modified Cognitive Interview were not susceptible to misinformation effects.

Understanding juror perceptions of forensic evidence: investigating the impact of case context on perceptions of forensic evidence strength.

The most widely accepted model of juror decision making acknowledges the importance of both the case-specific information presented in the courtroom, as well as the prior general knowledge and beliefs held by each juror. The studies presented in this paper investigated whether mock jurors could differentiate between evidence of varying strengths in the absence of case information and then followed on to determine the influence that case context (and therefore the story model) has on judgments made about the strength of forensic DNA evidence. The results illustrated that mock jurors correctly identified various strengths of evidence when it was not presented with case information; however, the perceived strength of evidence was significantly inflated when presented in the context of a criminal case, particularly when the evidence was of a weak or ambiguous standard. These findings are discussed in relation to the story model, and the potential implications for real juries.

Male rape victim and perpetrator blaming.

One of four possible vignettes manipulated by (a) level of rape myth contained within them (low vs. high) and (b) type of rape (stranger vs. acquaintance) was presented to participants followed by scales measuring victim blame, perpetrator blame, belief in a just world, sex-role egalitarian beliefs, and male rape myth acceptance. Victim blaming was predicted by male rape myth acceptance. Perpetrator blaming was predicted by male rape myth acceptance and sex-role egalitarianism. Differences were found in victim and perpetrator blaming in terms of stranger and acquaintance rape and also in relation to manipulating the level of rape myths. Findings are discussed in relation to the previous literature on rape victim and perpetrator blaming.

Entrevista de crianças e adolescentes em contexto policial e forense: uma perspectiva do desenvolvimento / Investigative interviewing of children and adolescents: a developmental perspective

Conhecer as diferentes etapas do desenvolvimento humano é uma competência essencial para o entrevistador em contexto policial e forense. É imprescindível adaptar a entrevista em função da avaliação das competências da testemunha. Este artigo caracteriza as etapas do desenvolvimento humano ao longo da infância e adolescência, destacando o desenvolvimento da memória e outras competências relevantes para a entrevista de testemunhas. Analisou-se ainda a adequabilidade de várias metodologias utilizadas para este fim, salientando algumas diretrizes fundamentais para a condução de uma boa entrevista. Por fim, focou-se na Entrevista Cognitiva Melhorada enquanto técnica promissora para entrevistar crianças e adolescentes. Pretende-se não apenas rever de forma crítica a literatura existente, mas também construir um guia para os profissionais desta área.

Knowing the different developmental stages is an essential skill for the forensic or police interviewer. It is crucial to adapt the interview according to the witness developmental assessment. This article describes the stages of human development throughout childhood and adolescence, with particular emphasis on the development of memory and other skills involved in the interview process. The appropriateness of several methodologies used for interviewing child witnesses is discussed, as well as some fundamental guidelines for conducting a good interview. Lastly, the article focuses on the Enhanced Cognitive Interview as a promising technique for interviewing children and adolescents. The aim of this study is not only to critically review the existing studies, but also to write a guide for professionals in this area.

Increasing cognitive load to facilitate lie detection: the benefit of recalling an event in reverse order.

In two experiments, we tested the hypotheses that (a) the difference between liars and truth tellers will be greater when interviewees report their stories in reverse order than in chronological order, and (b) instructing interviewees to recall their stories in reverse order will facilitate detecting deception. In Experiment 1, 80 mock suspects told the truth or lied about a staged event and did or did not report their stories in reverse order. The reverse order interviews contained many more cues to deceit than the control interviews. In Experiment 2, 55 police officers watched a selection of the videotaped interviews of Experiment 1 and made veracity judgements. Requesting suspects to convey their stories in reverse order improved police observers' ability to detect deception and did not result in a response bias.

False reports of childhood events in appropriate interviews.

The present study employed the "parental misinformation" paradigm to examine whether individuals report false events from their childhood even when they are interviewed in an appropriate manner by a trained interviewer. Each participant was interviewed on three occasions. By the final interview, one participant produced a "full" report, and six participants produced "partial" reports, of childhood events that did not occur. Although participants reported perceiving greater pressure to report the false events than the real events, independent judges' ratings of social pressure in the interviews did not differ as a function of what type of event participants were being asked about. Participants also reported higher confidence in their parents', compared to their own, recall of events from their childhood. False reports were also positively correlated with scores on both the full and the revised versions of the Dissociative Experiences Scale, and negatively correlated with score on the Self-Monitoring scale. These results indicate that, despite being interviewed in an appropriate manner by a trained interviewer, some participants will falsely report events from their childhoods.

Legal psychology in the twenty-first century.

BACKGROUND: This paper examines some of the major topics that legal psychology began to focus on at the end of the last century. AIM: The purpose is to contend that such topics (the reliability of ear-witness testimony, the conducting of identification parades/line ups, the interviewing of suspects, the interviewing of vulnerable witnesses/victims) are deserving of greater attention in this new century. CONCLUSIONS: Legal psychologists should be brave enough to research with methodological rigour complex, real-world topics of importance to society and to advise relevant professional groups on how to improve their performance.

People's insight into their own behaviour and speech content while lying.

The present experiment examined participants' insight into their own behaviour and speech content while lying. It was hypothesized that participants would believe that while lying they show more behaviour stereotypical of lying than they in fact do (Hypothesis 1), whereas they would believe that their own speech content while lying contains fewer stereotypical features than in fact is true (Hypothesis 2). A stereotypical response was defined as a response people generally believe liars usually show. A total of 86 nursing students were interviewed twice about a film they had just seen. During one interview they were asked to tell the truth whereas they had to lie in the other interview. All interviews were videotaped, transcribed and then scored by independent coders. The coders' analyses reveal participants' actual behaviour and speech content. Participants themselves were asked to indicate in a questionnaire how they believed they behaved and what they believed they said in both interviews. To test the hypotheses, comparisons were made between participants' actual responses and their beliefs about their own responses. The results support both hypotheses and implications of these outcomes for the detection of deception are discussed.

Suspects, lies, and videotape: an analysis of authentic high-stake liars.

This study is one of the very few, and the most extensive to date, which has examined deceptive behavior in a real-life, high-stakes setting. The behavior of 16 suspects in their police interviews has been analyzed. Clips of video footage have been selected where other sources (reliable witness statements and forensic evidence) provide evidence that the suspect lied or told the truth. Truthful and deceptive behaviors were compared. The suspects blinked less frequently and made longer pauses during deceptive clips than during truthful clips. Eye contact was maintained equally for deceptive and truthful clips. These findings negate the popular belief amongst both laypersons and professional lie detectors (such as the police) that liars behave nervously by fidgeting and avoiding eye contact. However, large individual differences were present.
