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.     

An analysis of police officers' decisions about whether to refer cases of child abuse for prosecution

Facial composite research has mainly focused on their investigative value. No. comparable attention was drawn to their probative value – the extent to which a composite image may serve as incriminating or exonerating evidence against a defendant. The existing data resulting from mock-juror research allow only cautious conclusions and applies solely to the common law system. Therefore an experiment was conducted involving laypeople (N = 74) and prosecutor apprentices (N = 72). All participants received case materials of a robbery committed by a young male, including the victim's and defendant's testimonies and other evidence. In both samples, the facial composite evidence was manipulated so that participants viewed a composite image that was either a good or a poor match to the defendant. A facial composite that bore a strong resemblance to the defendant influenced the assessment of the eyewitness' credibility in the apprentices sample, but failed to affect other dependent variables. Surprisingly, laypeople ignored the facial composite no matter how well it resembled the defendant. Significant differences in the assessment of eyewitness' credibility, the strength of the defense case, the credibility of the defendant's alibi, and his culpability were found between the prosecutor apprentices and laypeople. The practical implications of these findings are discussed.     

Remembering remotely: would video-mediation impair witnesses' memory reports?

Witnesses often experience lengthy delays prior to being interviewed, during which their memories inevitably decay. Video-communication technology – favored by intergovernmental organizations for playing larger roles in judicial processes – might circumvent some of the resourcing problems that can exacerbate such delays. However, whereas video-mediation might facilitate expeditious interviewing, it might also harm rapport-building, make witnesses uncomfortable, and thereby undermine the quality and detail of their reports. Participants viewed a crime film and were interviewed either one day later via video-link, one day later face-to-face, or 1–2 weeks later face-to-face. Video-mediation neither influenced the detail or the accuracy of participants' reports, nor their ratings of the quality of the interviews. However, participants who underwent video-mediated interviews after a short delay gave more accurate, detailed reports than participants who waited longer to be interviewed face-to-face. This study provides initial empirical evidence that video-mediated communication (VMC) could facilitate the expeditious conduct of high-quality investigative interviews.     

Eye-closure improves memory for a witnessed event under naturalistic conditions

Eye-closure may help people remember live and videotaped mundane events and videotaped violent events. The present study extended this research by examining memory for a forensically relevant live event (a staged verbal altercation) and by interviewing witnesses under naturalistic conditions. Ninety-six witnesses were interviewed either inside in a quiet setting or outside on a busy street, with eyes open or closed. In free recall, eye-closure significantly increased the number of correct details reported, without harming testimonial accuracy. These benefits were significant for witnesses interviewed inside but not for witnesses interviewed outside. This finding highlights the potential role of spontaneous mental context reinstatement in the eye-closure effect. In cued recall, eye-closure improved fine-grain correct recall of visual details for both groups of witnesses. From an applied perspective, the findings suggest that police interviewers should instruct witnesses to close their eyes, both during initial statements taken on the street and during full interviews conducted at the police station.     

The devil is in the detail: deception and consistency over repeated interviews

ABSTRACT

Research indicates that truthful statements typically contain more details than fabricated statements, and that truth tellers are no more consistent than liars over multiple interviews. In this experiment, we examine the impact of (i) multiple interviewers and (ii) reverse order recall on liars’ and truth tellers’ consistency and amount of reported detail over repeated recall attempts. Participants either took part in a mock crime (lying condition) or an innocent event (truth telling condition) which they were subsequently interviewed about in two separate interview phases. Truth tellers provided more details overall, and more reminiscent details than liars. There were no differences between veracity groups for the number of omissions made or repetitions reported. Despite the popular belief that inconsistency is a cue to deception, we found little support for the notion that consistency (or lack of consistency) offers a diagnostic cue to deception. We found little evidence that switching interviewer or recalling in reverse order induced inconsistencies in liars. In fact, due to the number of reminiscent details in truth tellers’ accounts, our findings suggest that accounts provided by liars tend to be slightly more consistent than those provided by truth tellers.

Young children's responses to cross-examination style questioning: the effects of delay and subsequent questioning

In a single experiment with 5- and 6-year-old children, we examined whether the changes that children make in response to cross-examination style questioning vary as a function of delay and/or persist in subsequent interviews. Children visited the local police station; 1–3 days later they were interviewed in a direct examination format. Either 1–3 days or 8 months later, children were interviewed in a cross-examination format designed to persuade them to change their original responses. One week following the cross-examination interview, the direct examination questions were repeated. Relative to direct examination scores, the accuracy of children's reports decreased significantly during cross-examination, irrespective of delay. When children were interviewed again 1 week after cross-examination, however, their responses (and their accuracy levels) were very similar to those observed during the direct examination interview. That is, during cross-examination, children made changes to their earlier testimony even when their memory for the event remained intact.     

Gender aspects of inheritance strategies and land transmission in rural Scania,Sweden, 1720–1840

This study deals with gender aspects of land transmissions in pre-industrial Sweden. Although not supported by law, a clear mentality of male primogeniture among peasants existed in the Swedish countryside in the 18th century. In many cases, however, this ideal could never be realized, making the idea of the “family farm,” handed down from father to son for generations, more of a myth than a reality. This study uses postmortem inventories linked to tax registers and family reconstitutions for a sample of parishes in southern Sweden to show that various strategies were chosen when transferring the farm after the death of the husband or wife. Although sons were more likely to take over the farms, daughters (or more correctly sons-in-law) also frequently did so, as did, sometimes, more distant kin and non-kin. Moreover, it was not the case, as has sometimes been maintained, that daughters took over the farm only when no able-bodied sons were available. On the contrary, daughters (sons-in-law) quite frequently took over the farm even when sons were present. The decision on land transmission was part of a more general family strategy concerning reproduction (access to marriage and household formation) as well as old-age security.     

Family strategies concerning migration and occupations of children in a market-oriented agricultural economy

This study focuses on family labor strategies in the 19th and early 20th centuries, using a database containing vital information on the lives of some 3000 persons born around 1830, 1850, and 1870 in the Groningen clay soil region—a predominantly agrarian area in the northern part of the Netherlands. Working-class families were moving from short-term survival strategies to long-term investment strategies in the last decades of the 19th century. Like other occupational groups, they tended to keep their children at home in larger numbers instead of finding them jobs as live-in workers—a change probably facilitated by improving real wages. Although such a change in family strategy implied lower earnings in the short run, children who stayed home experienced more upward social mobility in later life than those who left home early to become live-in servants. The increased preference for long-term investment strategies is also apparent in migratory patterns. Independent of the phases in the family cycle, working-class families became more inclined to migrate over longer distances, especially to America where unskilled laborers had better prospects.     

The family strategies concept: An evaluation of four empirical case studies

In this article, the preceding case studies are evaluated from the perspective of the family strategies concept. The studies have yielded new insights in the relationship between the family and the labor market and in the labor allocation within families. In addition, they have shown the tensions between individual life plans and collective needs. It has been difficult, however, to reach firm conclusions about which strategies were deployed by families. One of the problems is that the motives of the family members remain hidden. In addition, our databases need to be more finely tuned to the strategies concept. In particular, we know too little on the range of (strategic) options of families in the past.
