The Effect of a Standard to Improve Person Descriptions by Children

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger and were then later asked to describe and answer various questions about that person using a third-person standard/comparison. Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where female - did have a significant effect on the recall ability of male participants.     

Non-biased lineup instructions do matter – a problem for older witnesses

Abstract

From the limited literature on older witnesses’ identification performance it is known that they are less accurate on lineups compared to younger witnesses. What is less certain is why they show this age deficit and what can be done to aid their performance. Witnesses forgot being given non-biased lineup instructions informing witnesses that the perpetrator may or may not be present. More older witnesses than younger witnesses forgot and witnesses who failed to report remembering these instructions were significantly less accurate on the lineups. In addition, the current study investigated the use of sequential lineup presentation and stringent decision criteria to aid the performance of older witnesses. Sequential presentation was beneficial to both younger and older adults when the lineup was target absent (TA) but was detrimental when the lineup was target present (TP). Stringent decision criteria had no significant beneficial effect. Future directions for aiding older witnesses’ performance are discussed.     

PC_Eyewitness and the Sequential Superiority Effect: Computer-Based Lineup Administration

Computer technology has become an increasingly important tool for conducting eyewitness identifications. In the area of lineup identifications, computerized administration offers several advantages for researchers and law enforcement. PC_Eyewitness is designed specifically to administer lineups. To assess this new lineup technology, two studies were conducted in order to replicate the results of previous studies comparing simultaneous and sequential lineups. One hundred twenty university students participated in each experiment. Experiment 1 used traditional paper-and-pencil lineup administration methods to compare simultaneous to sequential lineups. Experiment 2 used PC_Eyewitness to administer simultaneous and sequential lineups. The results of these studies were compared to the meta-analytic results reported by N. Steblay, J. Dysart, S. Fulero, and R. C. L. Lindsay (2001). No differences were found between paper-and-pencil and PC_Eyewitness lineup administration methods. The core findings of the N. Steblay et al. (2001) meta-analysis were replicated by both administration procedures. These results show that computerized lineup administration using PC_Eyewitness is an effective means for gathering eyewitness identification data.     

An Evaluation of the Use of Videotaped Evidence for Juvenile Witnesses in Criminal Courts in England and Wales

For the first time, the UK Criminal Justice Act (1991) allowed the videotaped evidence of a child to be substituted for the child's evidence-in-chief in a criminal court. The present study is an evaluation of that legislation. One hundred and fifty children were observed testifying in a criminal court in the UK. The use of the videotaped evidence and subsequent cross-examination of the child witness (usually via the closed circuit television system) was also observed. The data base from the Lord Chancellor's Department of all trials involving child witnesses in England and Wales was also analysed. The results showed that the introduction of the video technology into the criminal courts reduced the levels of stress of child witnesses but did not increase the conviction rates.

‘Reasonable’ perceptions of stalking: the influence of conduct severity and the perpetrator–target relationship

Abstract

This study sought to examine the state of police interviews with children in Norway set against the various models that have been developed in the United Kingdom. UK models attempt to accord with psychological principles that lead to effective interviewing and so, if appropriately followed, should enhance the elicitation of accurate material. Set against these principles of best practice, an analysis of 11 police interviews indicated that a number of insppropriate and ineffective strategies appear to be used in police interviews in Norway. These included a preponderance of closed questions, a large number of instructions, paraphrasing and not giving the child enough time to talk. Results suggest that the Norwegian system needs to be made more aware of the psychological vulnerabilities that can lead to suggestibility in children.

Catching the Bad Guy: Morphing Composite Faces Helps

Composite faces built by eyewitnesses commonly are poor likenesses of the target face. When there are multiple witnesses, however, an opportunity exists to morph the composites. Morphs were rated as more similar to the target face than were the mean ratings of the individual composites. However, as hypothesized, the morph also came to resemble non-target faces more than the individual composites did (a prototype effect). This prototype effect was so strong that the morphs resembled non-targets more than the individual composites resembled the targets. In addition, morphing composites produced an attractiveness bias, which made the morphing of composites less effective for less attractive targets. Even when the prototype effect and the attractiveness bias were controlled for, however, a true morph-superiority effect continued to exist. The author won the Psi Chi/APS Albert Bandura Graduate Research Award in 2005--2006 for this study.     

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.

Can a witness report hearsay evidence unintentionally? The effects of discussion on eyewitness memory

Abstract

When eyewitnesses are exposed to misinformation about an event from a co-witness, they often incorporate this misinformation in their recall of the event. The current research aimed to investigate whether this memory conformity phenomenon is due to change in the witness's memory for the event, or to social pressures to conform to the co-witness's account. Participants were shown a crime video and then asked to discuss the video in groups, with some receiving misinformation about the event from their discussion partners. After a one-week delay some participants were warned about possible misinformation before all participants provided their own account of the event. In Study 1, participants made remember/know judgments about the items recalled, and in Study 2 they indicated the source of their memories. Co-witness information was incorporated into participants’ testimonies, and this effect was not reduced by warnings or source monitoring instructions, suggesting memory change may have occurred. However, there was some indication that remember/know judgments may help distinguish between ‘real’ memories and co-witness information.     

Younger and older adults’ lie-detection and credibility judgments of children's coached reports

ABSTRACT

Previous research has examined young and middle-aged adults’ perceptions of child witnesses; however, no research to date has examined how potential older adult jurors may perceive a child witness. The present investigation examined younger (18–30 years, N?=?100) and older adults’ (66–89 years, N?=?100) lie-detection and credibility judgments when viewing children's truthful and dishonest reports. Participants viewed eight child interview videos where children (9–11 years of age) either provided a truthful report or a coached fabricated report to conceal a transgression. Participants provided lie-detection judgments following all eight videos and credibility assessments following the first two videos. Participants completed a General Lifespan Credibility questionnaire to assess credibility evaluations across various witness ages. Lie-detection results indicated that older adults had significantly lower discrimination scores, a stronger truth bias, and greater confidence compared to younger adults. Older adults also rated children as more competent to testify in court, credible, honest, believable, and likeable than younger adults. Participants with greater differences in their credibility evaluations for truth and lie-tellers were significantly more accurate at detecting lies. Responses to the Lifespan Credibility questionnaire revealed significant differences in younger and older adults’ credibility evaluations across the lifespan.     

The Relationship Between Crime Reporting and Police: Implications for the Use of Uniform Crime Reports

Empirical studies that use reported crime data to evaluate policies for reducing crime will understate the true effectiveness of these policies if crime reporting/recording behavior is also affected by the policies. For instance, when the size of the police force increases, changes in the perceived likelihood that a crime will be solved may lead a higher fraction of victimizations to be reported to the police. In this paper, three data sets are employed to measure the magnitude of this reporting bias. While each of these analyses is subject to individual criticisms, all of the approaches yield similar estimates. Reporting bias appears to be present but relatively small in magnitude: each additional officer is associated with an increase of roughly five Index crimes that previously would have gone unreported. Taking reporting bias into account makes the hiring of additional police substantially more attractive from a cost–benefit perspective but cannot explain the frequent inability of past studies to uncover a systematic negative relationship between the size of the police force and crime rates.     

The impact of questioning style on the content of investigative interviews with suspected child sexual abuse victims

Abstract

This study explored the influence of question type and interviewer style on the quantity and quality of responses offered by children in interviews for suspected sexual abuse. The analysis covered 36 investigative interviews conducted by polia officers under the Memorandum of Good Practice with children aged 4–7, 8–11 and 12–14 years. The dependent measures were the temporel length of children's answers and the number of criteria derived from Criteria Based Cornent Analysis (CBCA) they contained. Only 2% of all questions were open-ended, but just 3% were judged leading. Open questions were most effective with 12–14 year olds but not with younger children who provided nose information in response to specific yet not leading or closed questions. Longer answers containing move CBCA criteria were associated with interviews containing many affirmative utterances and verbal affirmations and a brief rapport. The implications of these findings for interview theory and practice are briefly discussed.
