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. Participants 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.

Sketching to Remember: Episodic Free Recall Task Support for Child Witnesses and Victims with Autism Spectrum Disorder.

Deficits in episodic free-recall memory performance have been reported in children with autism spectrum disorder (ASD), yet best practice dictates that child witness/victim interviews commence with a free-recall account. No ‘tools’ exist to support children with ASD to freely recall episodic information. Here, the efficacy of a novel retrieval technique, Sketch reinstatement of context (Sketch-RC), is compared with mental reinstatement of context and a no support control. Ninety children (45 with ASD; 45 matched typically developing) viewed a stimulus film, and were interviewed using one of the aforementioned techniques. The Sketch-RC technique was most effective, improving ASD participants’ remembering without a concomitant increase in intrusions. This procedure offers a population-appropriate method for supporting free recall in criminal justice settings.

Finding a Needle in a Haystack: Toward a Psychologically Informed Method for Aviation Security Screening

Current aviation security systems identify behavioral indicators of deception to assess risks to flights, but they lack a strong psychological basis or empirical validation. We present a new method that tests the veracity of passenger accounts. In an in vivo double-blind randomized-control trial conducted in international airports, security agents detected 66% of deceptive passengers using the veracity test method compared with less than 5% using behavioral indicator recognition. As well as revealing advantages of veracity testing over behavioral indicator identification, the study provides the highest levels to date of deception detection in a realistic setting where the known base rate of deceptive individuals is low.

When help becomes hindrance: Unexpected errors of omission and commission in eyewitness memory resulting from change temporal order at retrieval?

An experimental mock eyewitness study is reported that compared Free and reverse order recall of an empirically informed scripted crime event. Proponents of reverse order recall suggest it facilitates recovery of script incidental information and increases the total amount of information recalled. However, compared with free recall it was found to impair overall retrieval performance, resulting in fewer script consistent events, reduced recall of correct information, increased confabulations, and lowered accuracy proportional to items retrieved. The disruptive effects of reverse order are interpreted as providing evidence for the role of temporal clustering in guiding retrieval. Impairment induced by reverse order continued to influence retrieval negatively even during a secondary free recall phase suggesting it encourages confabulations. The results indicate that the technique should be used with caution, and only when retrieval by free recall has been exhausted.

Psychology and interviewing: what direction now in our quest for reliable information?

Purpose – The purpose of this paper is to discuss two distinct but interrelated areas, namely witness/victim and suspect interviewing, and to argue that both must continue to evolve, suggest how they might do so, and that this process must be driven by emergent theory and contemporary empirical research. Design/methodology/approach – The paper outlines the impact of psychological theory and empirical research to investigative interviewing in recent decades. Findings – It is argued that in order to stay ahead of the game, the field of investigative interviewing (suspect and witness) must continue to evolve in such a manner that not only protects and fosters the important practitioner/academic relationship, but also ensures that future directions are driven by empirical research, with recourse to emergent theory. Originality/value – The paper outlines the impact of psychological theory and empirical research on investigative interviewing and the consequent enhancement of the interviewing of both suspected offenders and witnesses. The paper demonstrates that working closely together academic research can make a difference, and influence law, policy decisions and training guidelines in order to improve practice.

Drawing to remember: external support of older adults' eyewitness performance.

Although healthy aging is accompanied by a general decline in memory functioning, environmental support at retrieval can improve older adults’ (+65 years) episodic remembering. Despite those over the age of 65years representing a growing proportion of the population, few environmental retrieval support methods have been empirically evaluated for use with older witnesses and victims of crime. Here, the efficacy of a novel retrieval technique, the Sketch Mental Reinstatement of Context, is compared with a standard Mental Reinstatement of Context and a no support control (Control). Fifty-one participants witnessed an unexpected live event, and 48 hours later were interviewed using one of three aforementioned techniques. In line with predictions emanating from cognitive theories of aging and the environmental support hypothesis, participants in the Sketch Mental Reinstatement of Context condition recalled significantly more correct information and fewer inaccurate items. The Sketch Mental Reinstatement of Context technique appears to scaffold memory retrieval in an age-appropriate manner during a post-event interview, possibly by encouraging more effortful retrieval and reducing dual-task load. As such, this procedure offers an effective alternative to current approaches, adding to the toolbox of techniques available to forensic and other interviewers.

Drawing the answers: Sketching to support free and probed recall by child witnesses and victims with autism spectrum disorder

The success of witness interviews in the criminal justice system depends on the accuracy of information obtained, which is a function of both amount and quality of information. Attempts to enhance witness retrieval such as mental reinstatement of context have been designed with typically developed adults in mind. In this article, the relative benefits of mental and sketch reinstatement mnemonics are explored with both typically developing children and children with autism. Children watched a crime event video, and their retrieval of event information was examined in free and probed recall phases of a cognitive interview. As expected, typically developing children recalled more correct information of all types than children with autism during free and probed recall phases. Sketching during free recall was more beneficial for both groups in both phases in reducing the amount of incorrect items, but the relative effect of sketching on enhancing retrieval accuracy was greater for children with autism. The results indicate the benefits of choosing retrieval mnemonics that are sensitive to the specific impairments of autistic individuals and suggest that retrieval accuracy during interviews can be enhanced, in some cases to the same level as that of typically developing individuals.

Perceptions of psychological coercion and human trafficking in the West Midlands of England: Beginning to know the unknown

Modern slavery is less overt than historical state-sanctioned slavery because psychological abuse is typically used to recruit and then control victims. The recent UK Draft Modern Slavery Bill, and current UK government anti-slavery strategy relies heavily on a shared understanding and public cooperation to tackle this crime. Yet, UK research investigating public understanding of modern slavery is elusive. We report community survey data from 682 residents of the Midlands of England, where modern slavery is known to occur, concerning their understanding of nonphysical coercion and human trafficking (one particular form of modern slavery). Analysis of quantitative data and themed categorization of qualitative data revealed a mismatch between theoretical frameworks and understanding of psychological coercion, and misconceptions concerning the nature of human trafficking. Many respondents did not understand psychological coercion, believed that human trafficking did not affect them, and confused trafficking with immigration. The public are one of the most influential interest groups, but only if well informed and motivated towards positive action. Our findings suggest the need for strategically targeted public knowledge exchange concerning this crime.
