The cognitive interview: Inexperienced police officers' perceptions of their witness/victim interviewing practices

Purpose. The primary objectives of the study reported here were twofold. First, to investigate less experienced frontline police officers' perceptions of their witness interviewing practices with specific reference to their use of the ten cognitive interview components taught during initial PEACE (a mnemonic for the stages of the interview; Planning and preparation, Engage and explain, Account, Closure and Evaluation) interview training. Second, to investigate this group of officers' practical experiences of interviewing witnesses. Method. A sample of 221 young, in‐service, non‐specialist police officers from five UK police forces completed a self‐report questionnaire concerning their perceived witness interviewing practices. Respondents were surveyed about their use of the PEACE cognitive interview components, their practical experiences of interviewing witnesses and victims, and their views on investigative interviewing training. Results. There was a consensus among these officers that they perceived using some of the PEACE cognitive interview components more frequently and perceived some of them to be more effective than others. Conclusion. This study provides a unique insight into the perceived interviewing practices of some of the least experienced and the least trained investigative interviewers who conduct the majority of frontline witness interviews. These officers report feeling inadequately trained, under pressure and generally ill equipped to conduct a PEACE cognitive interview.     

The Cognitive Interview: novice police officers' witness/victim interviewing practices

Abstract

The objective of this study was to investigate novice police officers’ witness interview practices immediately post investigative interview training (known as PEACE) with reference to the eight Cognitive Interview (CI) components taught. Forty-eight UK police officers took part as interviewers. Forty-eight undergraduates participated as mock witness; they viewed a non-violent crime video and 2 days later were individually interviewed by a police officer. Interviews were recorded and rated for officers’ application of the CI procedure.

Despite having recently completed the only training available to them no officer applied or attempted to apply the CI procedure in its entirety. However, some of the individual CI components were applied more frequently than others. This study provides a unique insight into the interviewing practices of some of the least researched, least experienced, and least trained investigative interviewers who, nonetheless, conduct witness interviews on a daily basis. The emergent picture suggests that either the CI procedure currently taught to novice police officers is too complex at so early a stage in their police career and/or that the current training may be insufficient to equip them with the skills necessary to effectively apply the procedure.     

Modifying the cognitive interview: countenancing forensic application by enhancing practicability

The UK investigative interview model advocates police officers use the cognitive interview (CI). However, research has indicated that many officers perceive the CI as too cumbersome, complex, and time consuming for some types of crime. With this in mind we investigate the efficacy of two CI procedures, which have been substantially modified to enhance forensic practicability and retain the empirically demonstrated CI superiority effect. Employing the mock witness paradigm, both are compared to the procedure currently taught to UK police officers. Participant's memorial performance revealed no differences across interview conditions for the amount of correct and incorrect recall. However, those interviewed using the modified procedures confabulated less and were more accurate. Considering type of information recalled (person, action, object, and surrounding), no differences were found across conditions for correct or confabulated type recall. However, the two modified CIs elicited fewer incorrect person and object information items. Further, they were shorter in duration than the current procedure. Hence, for frontline less serious crime, or in time critical situations, the modified procedures may be viable alternatives. These findings and their implications are discussed.     

QUESTIONING SEQUENCES IN CANADIAN POLICE INTERVIEWS: CONSTRUCTING AND CONFIRMING THE COURSE OF EVENTS?

A content analysis of 19 Canadian police interviews with adult witnesses revealed that several of the interviewing strategies used by officers ran counter to the recommendations in the literature. Specifically, interviewers interrupted the witness more than was necessary, rarely employed any cognitive techniques to enhance memory recall and asked far more closed than open-ended questions. Further, in terms of the sequencing of questions, a pattern emerged across interviews that suggested that officers first “help” the witness construct the event and then, through a rapid sequence of “yes/no” questions, seek to confirm the account. We argue that this pattern of questioning may suggest that officers are pursuing an assumed version of events and that exploring interviews from a sequencing perspective may prove beneficial in identifying possible biased versions of events.     

Police officers’ and Registered Intermediaries’ use of drawing during investigative interviews with vulnerable witnesses

ABSTRACT

Attempts to enhance episodic retrieval focus largely on verbal strategies which do not always address the limited or impaired free recall ability of vulnerable witnesses. Asking a witness to draw while recalling episodic information has long been deemed an effective method of improving communication and cognitive performance. Thus far, research has revealed these effects within laboratory settings but with scarce attention paid to real-life interview practice. In this paper, we explore police officers’ and Registered Intermediaries’ use of drawing during investigative interviews with vulnerable witnesses. A sample of specialist practitioners (n?=?85), comprising of vulnerable witness interviewing police officers (n?=?50) and Registered Intermediaries (n?=?35) completed a self-report questionnaire. As expected, frequent use of drawing was reported by both practitioner groups, and there was a positive correlation between reported use and perceived effectiveness. There were similarities between groups in reported techniques employed when using drawing, but some differences were apparent and these were attributed to the differing functions in police and Registered Intermediary roles. Overall, a consensus between empirical research and practice is evident, but these findings warrant further exploration in order to establish whether such practice is wide-spread.     

Effects of the NICHD Protocol Training on Child Investigative Interview Quality in Korean Police Officers

This study was conducted to determine, by comparing pre- and post-training interview of 18 Korean police officers, whether training in use of the NICHD Protocol improved the quality of investigative interviews of allegedly abused child victims. Results showed that Korean police officers more often followed the Protocol structure -they introduced themselves, explained the ground rules, and conducted episodic memory training-after they had been trained. Moreover, police officers used approximately three times as many desirable prompts (such as invitations and facilitators) and fewer suggestive prompts in interviews conducted after as opposed to before the training. Invitations elicited approximately four to seven times more details on average than the least productive prompts. These results confirmed that the NICHD Protocol is effective when used to interview alleged child abuse victims in East Asia.     

Police officers' perceptions of older eyewitnesses

Purpose. This study examined United Kingdom police officers' perceptions about older witnesses (>60 years) and their thoughts about employing the cognitive interview (CI) with this group. Method. A questionnaire was used to assess officers' opinions about current interviewing protocols for older witnesses, including the CI, and to explore the challenges involved with interviewing older witnesses. Results. Over half of the officers surveyed perceived older witnesses to be less reliable and less thorough than younger witnesses. Many officers lacked confidence in dealing with the emotional distress and memory loss often displayed by older witnesses and victims. Several officers stated they were inadequately trained and had insufficient time to devote to interviewing in general. Moreover, the number of officers who considered the CI to be helpful with older witnesses was roughly equivalent to the number of officers who believed it was not. Conclusions. These results suggest that police officers, like mock jurors, consider older adult witnesses and victims to be less reliable and thorough than younger adult witnesses. Furthermore, the results indicate that many officers are not always satisfied with their interviews of older witnesses and victims. Implications for officer training are discussed.     

Intoxicated eyewitnesses: prevalence and procedures according to England’s police officers

Despite the apparent role alcohol plays in criminal offences, there is at present no evidence available as to the extent of the problem of intoxicated witnesses within England. To address this lack of research, police officers from seven constabularies completed an online survey addressing issues such as the prevalence of intoxicated witnesses, how officers determine intoxication, the procedures employed and their effectiveness. Officers indicated that intoxicated witnesses were a common, to very common, occurrence with most officers determining intoxication through physical symptoms and the witness’s own admission. In terms of interviewing witnesses, the majority of officers indicated that initial details were taken whilst witnesses were intoxicated, but the evidential interview was taken when sober. Officers also indicated that if the witness was intoxicated then the case was less likely to proceed to court and that officers viewed the witness as less accurate. These findings are considered from a criminal justice perspective and discussed in relation to future research.     

Spaced cognitive interviewing: Facilitating therapeutic and forensic narration of traumatic memories

Abstract

The evolution of the cognitive interview (CI) is reviewed from the original package of memory-enhancing techniques through to the revised (or enhanced) CI, and the cognitive approach now taught to police officers in UK. Many officers are reluctant to apply CI, particularly to traumatised victims. The traumatising effects of crime are examined in terms of immediate response and the potential for an acute stress response and post-traumatic stress disorder, with subsequent re-experiencing of dissociated traumatic memories in the form of intrusive, unwanted imagery. Traumatic memories are described, particularly their accuracy, detail and persistence. The therapeutic potential of prolonged experience of distress while narrating the content of traumatic imagery is explained. An approach to maximising the disclosure of dissociated detail - spaced cognitive interviewing (SCI) - is described and case material presented illustrating its forensic and therapeutic application. The practice and practical implications of SCI are summarised.     

Brief Mental Skills Training Improves Memory and Performance in High Stress Police Cadet Training

Psychological performance training has been shown to mitigate the negative effects of stress for police officers. We contributed to this body of evidence using techniques in breathing, mental performance imagery, and attentional focus. One group (experimental) of police academy cadets was trained in these techniques to deal with the stressful event of being sprayed with oleoresin capsicum (OC). Their physiological and behavioral responses to the event were compared to a control group of cadets. The results showed the experimental group demonstrated significantly better memory recall of salient aspects of the OC spray event and that cadets from both groups using controlled breathing during the event scored significantly higher in memory recall. Several trends were found that further suggested the effectiveness of psychological performance training. While heart rate increased from baseline to pre-OC and post-OC measures across groups, there were no group differences at these time points. Our findings add to the growing body of literature on psychological skill training effects on tactical performance and are notable for results of enhanced performance occurring with relatively brief training in the psychological techniques. Because of the ecological design, the findings should generalize to other high stress encounters in policing.     

A field study of adult witness interviewing practices in a Canadian police organization

Purpose. The current study examined witness interviewing practices in a Canadian police organization. The effect of interviewer, interviewee, and interview characteristics on those practices was also examined. Method. Ninety witness interviews from a Canadian police organization were coded for the following interviewing practices: types of questions asked (i.e. open‐ended, probing, closed‐ended, clarification, multiple, leading, opinion/statement, and re‐asked), the number of interruptions, percentage of words spoken by interviewer, type of pre‐interview instructions (consequential vs. generic), and whether or not a free narrative was requested (and when requested during the interview). Characteristics pertaining to the interviewer (e.g. primary interviewer's age), interviewee (e.g. witness gender), and interview (e.g. crime type) were also coded. Results. Results showed that closed‐ended and probing questions were the most widely asked questions, and that open‐ended questions were asked relatively infrequently. It was also found that the 80–20 talking rule was violated in 89% of the interviews, interviewers rarely interrupted the witnesses, and free narratives were requested often. Overall, the effect of interviewer, interview, or interviewee characteristics on interviewing practices was minimal. Conclusions. The finding that scientifically prescribed interviewing practices are employed rarely by Canadian police officers highlights a need for increased professional interviewing training. The finding that practices are largely unaffected by personal and situational factors suggests that such training would be equally beneficial for all types of interviewers, interviewees, and contexts.     

Fatal impact? The effects of emotional arousal and weapon presence on police officers' memories for a simulated crime

Purpose . (1) To investigate the effects of emotional arousal and weapon presence on the completeness and accuracy of police officers' memories; and (2) to better simulate the experience of witnessing a shooting and providing testimony. Methods . A firearms training simulator was used to present 70 experienced police officers with either a shooting or a domestic dispute scenario containing no weapons. Arousal was measured using both self‐report and physiological indices. Recall for event details was tested after a 10‐minute delay using a structured interview. Identification accuracy was assessed with a photographic line‐up. Results . Self‐report measures confirmed that the shooting induced greater arousal than did the other scenario. Overall, officers' memories for the event were less complete, but more accurate, when they had witnessed the shooting. The recall and line‐up data did not support a weapon focus effect. Conclusions . Police officers' recall performance can be affected both qualitatively and quantitatively by witnessing an arousing event such as a shooting.     

The enhanced cognitive interview: could individual differences in visuo-spatial working memory explain differences in recalling an event?

The Enhanced Cognitive Interview (ECI) is one of the most useful witness interviews, consisting of 5 techniques (context reinstatement: CR; report everything: RE, mental imagery: MI, change order: CO and change of perspectives: CP) aimed at increasing both the quantity and the quality of elements recalled. All the techniques require mental imagery skills. The present study investigates the relationship between forward and backward visuo-spatial working memory (VSWM) and correct elements recalled through the ECI with respect to its techniques. 99 college students (48 males) watched a color videotape of a fictional crime and performed a visuo-spatial working memory task. The following day they were interviewed about what they had seen. Results showed that high forward VSWM capacity has a role in favoring the total amount of correct information recalled, specifically in the MI technique. This suggests that maintaining and processing mood-related contents in VSWM is easier for individuals with high working memory skills.     

The theory of planned behavior and policing: how attitudes about behavior,subjective norms,and perceived behavioral control affect the discretionary enforcement decisions of police officers

This research used qualitative methods to investigate police officer decision-making processes within the context of the theory of planned behavior from the discipline of psychology. Interviews with police officers were conducted to elicit how the constructs of attitudes about enforcement behaviors, subjective norms, and perceived behavioral control manifest themselves in a policing context and how they affect the enforcement decisions that police officers ultimately make. The results indicated that officer attitudes about enforcement behaviors impact the decisions officers make with the caution that the impact of these attitudes varies across varying situational contexts. In terms of subjective norms, officers were primarily concerned with supervisor expectations more than the expectations of coworkers or the community in general. Officer decisions are also impacted by perceived limits on their discretion with these perceived limits being largely conditioned by offense seriousness. Theoretical implications of the findings and directions for future research are discussed.     

Police Officers’ Theories of Crime

What factors do police officers point to in explaining offending and victimization? A limited amount of prior research has addressed this question, despite the possibility that such theories impact police practice. Moreover, the findings that do exist are based solely on municipal police; yet a different socio-environmental context could lead officers to adopt different explanations. In the present paper, we draw on qualitative data obtained in interviews with campus police officers to explore how they explain common crimes on campus. They theorized petty larceny, underage drinking, and drug possession to result from a variety of factors, including opportunity, social learning, supervision, culture, peer pressure, the psychopharmacological effect of alcohol on crime, and deterrence; as a collective, these ideas form officers’ rational choice theories. After presenting our findings, we suggest how officers’ explanations of crime may be shaped by working in particular contexts and also affect how they police; implications for future research and police practice are discussed.     

The Psychological Impact on Police Officers of Being First Responders to Completed Suicides

When a suicide is completed, police officers are often among the first responders. Little attention has been paid to the emotional and psychological impact on the police officer in this specific situation. This study examines the effects encounters with completed suicides have on the emotional and psychological well-being of the police officer. This is a qualitative study, which intends to bring alive the feelings, thoughts, actions, choices, and challenges of police officers who have encountered completed suicides as imparted through participants' stories. Interviews were done with eight police officers. In addition, interviews were done with a coroner, a police chaplain, and a police psychologist to add some unique perspectives to the police officers’ experiences of encountering completed suicides. Interviews were done in a semi-structured, focused format involving an ongoing fine-tuning of questions. The overarching finding reveals the central role played by police culture in shaping how police officers come to perceive this experience, and how they subsequently choose to mediate it. This study identifies ten strategies police officers use to mediate this experience, and discusses the possible psychological consequences of employing each strategy.     

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.     

Eyewitness Memory for Firearms: Narrative Accounts and Specific Questioning in the Elucidation of Accurate Information

Much eyewitness research has addressed memory for persons and scenes, but limited work has addressed memory for firearms, frequently an important point in investigations and in court. The present research addressed this topic using the format of a traditional police interview, in which seventy subjects provided unrestricted free recall of a weapon seen in a crime situation, followed by responses to specific questions. Three firearms were used in a between-subjects format: a typical modern semi-automatic pistol, a less-typical Old West revolver, and an atypical single-shot muzzle-loading pistol. In the free recall stage, respondents provided about four times as many correct as incorrect details. However, in the specific-question stage, there were only 1.2 times as many new correct responses as new incorrect details, consistent with current cognitive theory. No difference between the weapons was observed in the production of correct responses, but the revolver and single-shot pistol resulted in more incorrect responses than did the modern semi-automatic, regardless of the saliency of weapon features. These results demonstrate the importance of the original, initial free recall phase in developing accurate identification of a given weapon, and of the type of weapon involved, and have important implications for police interviewing for accurate weapon identification.     

Child witness statement quality

Use of general questions in child witness interviews often limits the completeness of young children's recall. In this study experienced professionals interviewed 5–6 year olds and 8–9 year olds “as they would normally” about live events witnessed by the children. Interviewers' spontaneous use of general and specific questions was assessed, as were the effects of these question types on the children's recall. A main result was that the younger children would frequently fail to answer general questions but would then provide information relevant to these same questions later in the interview. Use of specific questions in these relatively naturalistic interviews did not necessarily improve the overall completeness of younger children's recall, contrary to some previous findings, although, in line with previous findings, such questioning reduced overall accuracy rates. These results highlighted the scale of the problem of “omission errors” in young children's recall. Implications for the use of general questions by professionals who interview child witnesses are discussed.     

The Decision to Become a Police Officer in a Legitimacy Crisis

This study examines how individuals make the decision to become police officers in the context of a police legitimacy crisis and how men and women’s decision-making processes may be different. In-depth interviews were conducted with 42 criminal justice college students who want to become police officers. Prospective police officers anticipated facing challenges as a direct result of the current climate surrounding American policing, which is characterized by decreased police legitimacy. On top of this, women anticipated facing more challenges than male officers due to their gender and underrepresentation in police work. However, women were uniquely motivated to enter policing to overcome gender-specific challenges and felt that they offered special skills that would provide solutions to the police legitimacy crisis. The paper draws implications for how agencies can identify more quality candidates and increase their representation of women.
