An examination of the Self-Administered Interview as a verbal veracity assessment tool

The self-administered interview (SAI) is a written eyewitness recall tool that elicits more information from cooperative witnesses than written free recall (WFR) formats. To date, SAI research has examined the accounts of cooperative people providing honest reports. In the current experiment, truthful and fabricating participants (N = 128) either completed a WFR or a SAI after witnessing a crime (initial account). After a 1-week delay, participants were interviewed verbally (subsequent interview). Truth tellers reported significantly more detail than liars in both the initial account and subsequent interview, and participants who completed the SAI reported more detail than those completing the WFR. Truth tellers repeated and omitted more information in the subsequent interview than liars; however, there was no significant difference in the number of reminiscent details reported. Although the SAI is effective in eliciting information as an initial eyewitness reporting tool, no benefits for the detection of deception were demonstrated.     

Eyewitness Evidence Obtained with the Self‐Administered Interview© Is Unaffected by Stress

The Self‐Administered Interview© (SAI) serves to elicit eyewitness statements directly after the crime. Witnesses could still experience stress then. Because stress during retrieval produces memory‐impairing effects, this study sought to compare the SAI with free recall under stress. An interaction between stress and interview was expected such that the SAI would elicit more comprehensive accounts than free recall in the control, but not in the stress group. One hundred and twenty‐seven participants underwent a stress or control task. They witnessed a live staged crime and completed an SAI or a free recall. The SAI elicited a higher number of correct verifiable event details and a higher number of correct and incorrect perpetrator details than free recall. Accuracy rates were unaffected. Unexpectedly, despite causing moderate stress‐induced cortisol elevations, stress exposure did not influence memory performance and did not interact with interview type. Hence, the SAI can safely be used, when witnesses are moderately stressed.Copyright © 2015 John Wiley & Sons, Ltd.     

Facilitating eyewitness memory in adults and children with context reinstatement and focused meditation

This study examined the comparative efficacy of two brief techniques for facilitating eyewitness memory in police investigations. Adult and child participants (N = 126; 64 children and 62 adults) who had viewed a videotape of a crime were subsequently tested for their memory of the event following either a focused meditation procedure (FM, derived from hypnotic interviewing techniques), a context reinstatement procedure (CR, a component of the cognitive interview), or a control procedure (no memory facilitation instructions). For both adults and children, the FM and CR procedures enhanced performance on both open‐ended and closed questions to levels above those achieved by controls, although those in the CR condition produced significantly more correct responses than those in the FM condition. However, only those in the CR group displayed elevated levels of confidence in relation to incorrect responses on closed questions. Implications for the possible use of such procedures are discussed.

Hypermnesia: A further examination of age differences between young and older adults

Previous studies that examined age differences in hypermnesia reported inconsistent results. The present experiment investigated whether the different study materials in these studies were responsible for the inconsistency. In particular, the present experiment examined whether the use of a video, as opposed to words and pictures, would eliminate previously reported age differences in hypermnesia. Fifteen college students and 15 older adults viewed a 3‐minute video clip followed by two free‐recall tests. The results indicated that older adults, as a whole, did not show hypermnesia. However, when older adults were divided into low and high memory groups based on test 1 performance, the high memory group showed hypermnesia whereas the low memory group did not show hypermnesia. The older adults in the low memory group were significantly older than the older adults in the high memory group – indicating that hypermnesia is inversely related to age in older adults. Reminiscence did not show an age‐related difference in either the low or high memory group whereas inter‐test forgetting did show an age difference in the low memory group. As expected, older adults showed greater inter‐test forgetting than young adults in the low memory group. Findings from the present experiment suggest that video produces a pattern of results that is similar to the patterns obtained when words and pictures are used as study material. Thus, it appears that the nature of study material is not the source of inconsistency across the previous studies.     

Source‐monitoring accuracy across repeated tests following directed forgetting

The repeated recall of items from lists that participants were earlier instructed to either remember or to forget was examined in two experiments. RR participants (those instructed to remember both lists they were presented) tended to recall more List 1 items than FR participants (those instructed to forget the first list and to remember the second list). FR participants recalled more List 2 items than did RR participants, but only when directed to report those items (Experiment 1), not when directed to report items from both lists (Experiment 2). Participants experienced difficulty correctly reporting the list source of items they recalled and incorrect source recall increased across tests, showing hypermnesia. This later result underscores the need for caution when assessing the accuracy of information retrieved from multiple sources across repeated tests. Together, the data patterns provide support for the retrieval dynamics account of hypermnesia, the context‐change account of directed forgetting, and limited support for the retrieval inhibition view of directed forgetting.     

The influence of schemas,stimulus ambiguity,and interview schedule on eyewitness memory over time

The authors examined how a crime schema influenced the types of details witnesses recalled over multiple interviews that varied in delay before the initial interview and between subsequent interviews. Accuracy data showed that, in general, schema-irrelevant traces experienced greater decay than schema-consistent and schema-inconsistent traces after the initial interview and that delaying the initial interview negatively affected recall at the initial interview but led to less decay over subsequent interviews. Ambiguity of the crime stimulus was also manipulated. Witnesses used their schema to interpret ambiguous information and, as a result, made more schema-consistent intrusions and less correct responses and were more likely to report false memories that involved conscious recollection (using the remember-know paradigm).     

Hypermnesia in free recall and cued recall

In three experiments, categorized lists and both free recall and cued recall tests were used to examine hypermnesia. In Experiment 1, materials were drawn from obvious and nonobvious categories in an attempt to vary the amount of relational processing at encoding. The study materials in Experiment 2 consisted of a long word list that comprised several exemplars from each of a number of common categories. In Experiment 3, a single exemplar was drawn from each of 45 categories. In each experiment, similar magnitudes of hypermnesia were obtained on free and cued recall tests. Examination of the specific items recalled across tests indicated that similar processes underlie the hypermnesic effect for both test conditions. Implications of the results for extant accounts of the hypermnesic effect are discussed. It is concluded that the dynamics of retrieval processes change in a systematic fashion across repeated tests and the retention interval following study and that an adequate account of the nature of these changes in retrieval dynamics is essential to our understanding of hypermnesia and related phenomena.     

The efficacy of mnemonic components of the cognitive interview: towards a shortened variant for time‐critical investigations

The cognitive interview utilizes mnemonic instructions and social facilitative techniques to increase correct recall from eyewitnesses without concomitant increases in errors. Recent studies however have suggested that police may neglect this technique in time‐critical situations. The present study investigated mnemonic components to determine whether a shorter, but still effective, technique was possible. Forty‐five participants viewed a film of a simulated crime and were interviewed with one of three techniques: the cognitive interview; a modified version that replaced the change order and change perspectives techniques with additional free recall attempts; or a structured interview. It was hypothesized that the modified technique would be as effective as the cognitive interview, while both would be superior to the structured interview. Results supported these hypotheses. Further analysis suggested that a shortened version, with the two mnemonics removed, may substantially reduce interviewing time while still offering an effective interview strategy in time‐critical situations.

Effect of Questioning Techniques and Interview Setting on Young Children's Eyewitness Memory

The goal of this research was to learn if supposed ineffective questioning techniques (e.g., question repetition within the interview) would reduce the accuracy of five-year-olds' eyewitness memory. In the first study, children viewed a slide show depicting a minor crime and were then interviewed either with a standard interview or one which incorporated ineffective questioning techniques. The results indicated that the type of interview did not affect children's eyewitness memory. In a second study, children were presented with the ineffective interview by an authoritative interviewer in a formal office setting. The results again indicated little influence of interview setting or question technique on children's eyewitness memory, identification accuracy, and suggestibility.     

Age‐related Differences in the Free‐recall Accounts of Child,Adolescent, and Adult Witnesses

Many researchers have examined the factors that affect children's ability to provide eyewitness evidence, leading to significant reform in policy and practice. In stark contrast, there has been virtually no eyewitness research conducted with adolescents, even though adolescents are still undergoing developmental changes that are likely to affect eyewitness performance. We compared the eyewitness performance of children, adolescents, and adults by showing them a brief film clip depicting a simulated crime and using cognitive interview instructions to elicit free‐recall accounts. Adolescents provided more information than children, but less information than adults. Accuracy did not differ with age. These data suggest that, like children, adolescents could benefit from specialised interview techniques that help them provide more complete accounts. Across all three age groups, individual differences in cognitive functioning contributed to variation in eyewitness performance, and eliciting a second free‐recall account increased the amount of information reported.

Protecting Against Misleading Post‐event Information with a Self‐Administered Interview

Two studies investigated whether an early recall opportunity, in the form of a self‐administered interview (SAI), reduced forgetting and protected against the negative consequences of post‐event misinformation. In both studies, participants viewed a simulated crime on DVD after which half immediately recorded their statement by using the SAI, whereas control participants did not have an immediate recall opportunity. Following a delay, participants were presented with misinformation encountered either in a misleading news report (Study 1) or in the form of misleading cued‐recall questions (Study 2). Results showed that participants who had completed a SAI after witnessing an event were significantly less prone to forgetting and significantly more resistant to the negative consequences of misinformation. The SAI was able to protect both the quantity and quality of information about a previously witnessed event. Applied implications are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

A comfortable witness is a good witness: rapport‐building and susceptibility to misinformation in an investigative mock‐crime interview

Major investigative interviewing protocols such as the Cognitive Interview recommend that investigators build rapport with cooperative adult witnesses at the beginning of a police interview. Although research substantiates the benefits of rapport‐building on the accuracy of child witness reports, few studies have examined whether similar benefits apply to adult witnesses. The present study investigated whether verbal rapport‐building techniques increase adult witness report accuracy and decrease their susceptibility to post‐event misinformation. One‐hundred eleven college adults viewed a videotaped mock‐crime, received post‐event misinformation (or correct information) about the crime, and were subsequently interviewed by a research assistant who built rapport (or did not build rapport) before recalling the mock‐crime. Results indicated that rapport‐building increased the quality of witness recall by decreasing the percentage of inaccurate and misinformation reported, particularly in response to open‐ended questions. We discuss implications and recommendations for law enforcement. Copyright © 2011 John Wiley & Sons, Ltd.     

Positive Emotions Speed Recovery from the Cardiovascular Sequelae of Negative Emotions

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the neutral and sad secondary films, those who viewed the positive films exhibited more rapid returns to pre-film levels of cardiovascular activation. In Study 2, 72 Ss viewed a film known to elicit sadness. Fifty Ss spontaneously smiled at least once while viewing this film. Compared to Ss who did not smile, those who smiled exhibited more rapid returns to pre-film levels of cardiovascular activation. We discuss these findings in terms of emotion theory and possible health-promoting functions of positive emotions.     

The cognitive interview: the efficacy of a modified mental reinstatement of context procedure for frontline police investigators

The current investigative interview framework for police officers in England and Wales (and many other countries) recommends the use of the cognitive interview (CI). One of the primary components of the CI is the mental reinstatement of context (MRC) instruction. However, research has consistently indicated that police officers do not regularly use this component and when they do it is often poorly applied. Thus the question arises as to whether some adjustment of the MRC component might enhance its forensic practicability. An initial investigation was conducted as to the efficacy of a more succinct and less complex MRC technique, namely a sketch plan mental reinstatement of context (Sketch MRC). Twenty‐four hours after having viewed a crime film, adult mock witnesses were interviewed employing the traditional MRC instruction, a Sketch MRC instruction or no mental reinstatement of context (No MRC). Analysis of overall memorial performance revealed the Sketch MRC to be as effective as the MRC and more effective than No MRC. Thus, for less serious crime the Sketch MRC technique may be a viable, less complex and less time consuming alternative. Copyright © 2008 John Wiley & Sons, Ltd.     

Beliefs and data on the relationship between consistency and accuracy of eyewitness testimony

Two studies concerned with consistency and accuracy of eyewitness testimony were conducted. In Study 1 potential jurors indicated the degree to which they considered that various witness on‐stand behaviours indicated testimonial accuracy. Witness statements that were inconsistent with previous statements were considered to be the strongest indicators of inaccuracy. Study 2 examined the relationship between consistency and accuracy of testimony. Witnesses viewed a film of a robbery and were interviewed twice (2 weeks apart) about the crime in a 4 (interview format)×2 (interview occasion) design. Regardless of whether consistency was operationalised in terms of direct contradictions between interviews, or degree of agreement on detail across interviews, no more than 10% of the variance in overall accuracy rate was explained by any individual measure. Number of contradictions and overall agreement between interviews did, however, make additive contributions to prediction of overall accuracy. Also, higher correlations between contradiction‐based consistency measures and interview two accuracy rate were detected. Neither consistency nor accuracy for specific testimonial dimensions were predictive of accuracy on the other dimensions, or overall accuracy. Copyright © 1999 John Wiley & Sons, Ltd.

Protecting and Enhancing Eyewitness Memory: The Impact of an Initial Recall Attempt on Performance in an Investigative Interview

Evidence‐gathering begins at the scene of an incident. Available witnesses may be asked to provide an account of what happened, either in response to an open request for information or, in some regions, by completing a Self‐Administered Interview (SAI©). In both cases, an investigative interview may be conducted at some later date. This study sought to determine the impact of an initial retrieval attempt on a subsequent interview. After exposure to a mock crime, participants completed an SAI© or a free recall (FR), or did not engage in an initial retrieval (Control). One week later, participants were interviewed with a Cognitive Interview. SAI© participants reported more correct information and maintained higher accuracy than FR and Control participants. Consistency analyses revealed that the SAI© was effective because it preserved more of the originally recalled items (Time 1) than did an initial FR, and not because it yielded new recollections at Time 2.

The role of recall time in producing hypermnesia

In two experiments subjects presented with either words or pictures showed improved recall over three successive recall tests for both types of materials, partially replicating Erdelyi’s finding of hypermnesia. However, these subjects did not recall more unique items than other subjects who received only one test equated in time with the three shorter ones. It is concluded that hypermnesia results from simply allowing subjects additional recall time. In a third experiment subjects were shown to recall additional information even after a long recall period employed during an experimental session. This surprising amount of item recovery during long recall periods is attributed to the use of subjective retrieval cues that are thought to function in a manner analogous to externally manipulated cues.     

Depictions of Murder in Maine: The Dominant Ideology Thesis

Recent research suggests that popular depictions of crime reflect and reinforce a dominant ideology in which criminals are viewed as rational actors who bear individual responsibility for crime. The research reported here employed a content analysis approach to examine depictions of 108 assailants found in media reports of murders that occurred in Maine from 2008 through 2012. While most of the depictions examined here describe crime as a matter of individual responsibility, this analysis found that many media depictions of Maine’s murderers include content that is sympathetic to the offender and some accounts raise questions about the effectiveness of police services, mental healthcare, and related social services.
