Misleading Suggestions can Alter Later Memory Reports even Following a Cognitive Interview

Taking an immediate recall test prior to misinformation exposure can increase eyewitness suggestibility—a finding termed retrieval‐enhanced suggestibility. Here, we examined whether retrieval‐enhanced suggestibility would occur when participants were administered an immediate Cognitive Interview (CI). The CI is an investigative interviewing technique that consistently elicits more correct details in memory reports than standard interviews. In this study, participants watched a video of a crime and then completed a distractor task (control condition), a free recall test, or the CI. They then heard misinformation presented in a narrative. Participants produced more accurate memory details in the CI than in free recall despite spending equal time on both tasks. However, the CI also increased the later report of misinformation relative to the control condition. These results show that initial retrieval can increase subsequent suggestibility even when such retrieval occurs under relatively ideal conditions. Copyright © 2013 John Wiley & Sons, Ltd.     

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 Enhanced Cognitive Interview: Testing Appropriateness Perception,Memory Capacity and Error Estimate Relation with Report Quality

The Enhanced Cognitive Interview (ECI) has been widely studied. However, research has overlooked witnesses' attitudes toward the interview and how error estimate and memory capacity relate to report quality. Participants watched a mock robbery video and were interviewed 48 hours later with either the Portuguese version of the ECI or a Structured Interview (SI). Participants interviewed with the ECI provided more information without compromising accuracy, particularly in free recall. Report accuracy was stable across interview phases and information categories. A higher perception of interview appropriateness (how witnesses evaluate the appropriateness of the interview procedure used) was linked with more detailed reports and more interest in being an interviewee. Participants over‐estimated their error rate, and their memory capacity was not related to witnesses' recall. It is essential to take into account their perception of interview appropriateness and use alternative methods to evaluate report quality. Major implications for real‐life investigations are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Mental reinstatement of the misinformation context and the misinformation effect in children and adults

The present study investigated the effects of mental reinstatement of the context in which misleading information about an event was presented on later recognition memory for the event. Five‐year‐olds, 7‐year‐olds and adults were shown a short video depicting a children's adventure and were asked a set of misleading questions to introduce misinformation one week later. Before the recognition memory test was administered another week later, half of the participants were given instructions to mentally reinstate the context of the misleading interview. Memory was assessed with a set of forced‐choice recognition questions once in the misleading interview context and for the children a second time at home one week later. When participants were instructed to mentally reinstate the context of the misleading interview prior to the recognition test, false memory reports occurred more often for adults than for children and had a stronger impact on peripheral information than on central information for both 7‐year‐olds and adults. When 5‐ and 7‐year‐olds were tested at home, false memory reports decreased. Thus, reinstating the context of an interview introducing misinformation can reduce the accuracy of memory reports; the context dependence of both accurate and inaccurate memory reports in children and adults is discussed.

Do Non‐Verbal Aids Increase the Effectiveness of ‘Best Practice’ Verbal Interview Techniques? An Experimental Study

Two experiments examined the effectiveness of non‐verbal interview aids as means of increasing the amount of information children report about an event under conditions designed to mimic their use in the field. In the first study, 27 5–7‐year‐old children took part in an event, and 7–10 days later were interviewed using the National Institute of Child Health and Human Development Protocol interview followed by an opportunity to draw the event or complete puzzles and, in turn, a second verbal interview. New information was reported following both drawing and puzzles and accuracy declined in both conditions, but drawing did not differentially influence recall. In the second experiment, dolls or human figure diagrams were introduced to clarify children's (N = 53) reports of touch as recommended in by some professionals, with a verbal interview serving as a control. Props did not increase the amount of information reported compared with best practice verbal techniques, but nor did they elevate errors. The findings support the use of a second recall attempt, but do not support the use of non‐verbal aids, even when these are used following professional recommendations.

Testing a modified cognitive interview with category clustering recall in Iran

The cognitive interview (CI) has been an effective method for interviewing eyewitnesses often leading to changes in legislation and practice in many countries. This study was the first to employ the CI in Iran and test whether category clustering recall (CCR) was superior to a free recall when incorporated within an investigative interview. A between‐subjects design assigned 66 participants to one of three interview conditions after they watched a mock robbery. The participants were interviewed 48 hr later using either a structured interview (SI), the CI, or a modified cognitive interview (MCI) that replaced free recall with CCR at the first retrieval attempt. Analysis of variance suggests CCR was more effective than free recall and the CI group recalled more information than the SI group, replicating the CI superiority effect. This has implications for law enforcement in Iran and worldwide by suggesting these techniques can be used to enhance recall.     

Cross‐examination: The Testimony of Children With and Without Intellectual Disabilities

The present study assessed how children with a range of cognitive abilities fared during a mock cross‐examination. Ninety children (aged 4 to 11 years; 18 with intellectual disabilities, 13 with borderline intellectual disabilities and 59 who were typically developing) witnessed a staged event, participated in an initial forensic interview (a few days later) and were cross‐examined by a barrister‐in‐training (10 months later). During cross‐examination, 98% of all children changed at least one response from their initial interview when challenged. However, group differences in performance (total number of changed responses, ‘resistance’ to challenges), controlling for age and memory for event details, were not significant or did not prove reliable at the level of individual group contrasts. Overall, little robust evidence for group differences in performance on cross‐examination could be identified, and memory for event details was the most reliable predictor of performance.

Early predictors of self‐regulation in middle childhood

The present study examined the contribution of caregiving practices at ages 4–5 (Time 1) to children's capacity for self‐regulation at ages 8–9 (Time 2). The multi‐ethnic sample comprised 549 children of National Longitudinal Survey of Youth (NLSY) participants. High levels of maternal warmth and low levels of physically punitive discipline at Time 1 were associated with a greater capacity for self‐regulation at Time 2. These associations remained significant once initial levels of self‐regulation were taken into account, indicating that the development of self‐regulation is open to caregiver influence during childhood. Neither child gender nor ethnicity moderated the effects of early parenting practices on later self‐regulation; the interaction between low maternal warmth and high discipline was also non‐significant. Findings add to the literature on how early parenting practices shape children's capacity for effective self‐regulation, and have implications for researchers and practitioners.

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.     

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.     

Do early interviews affect children's long‐term event recall?

The present study examined the effects of the timing of an initial interview on children's recall of an event over delays of 1 and 2 years. Fifty‐five children who had originally participated in a novel event when they were between 5‐ and 6‐years old and had been interviewed about it following either short (1 week or less) or long (1 or 6 month) delays were re‐interviewed 1 and 2 years after the original experience. An additional 20 children not interviewed prior to the 1‐year interview were included as a no‐prior‐interview control group. Long delays to the initial interview led to better open‐ended recall at the 1‐year delay than short delays to initial interview or no prior interview. However, initial interviews that followed short delays had a greater impact on children's responses to specific questions. The results suggest that prior interview history is an important consideration when examining the effects of long delays on children's event reports, and that the effects of the timing of an initial interview depend on the nature of the information recalled.

Arousal at encoding,arousal at retrieval,interviewer support,and children's memory for a mild stressor

The relations among children's physiological arousal at encoding and retrieval, interviewer‐provided social support and children's memory for a mild stressor were examined in 109 five‐ and six‐year‐olds. The children came to a research laboratory and watched a fear eliciting video clip. A week later, their memory for the video clip was tested by either a supportive or nonsupportive interviewer. While watching the video and completing the memory interview, children's heart rate was monitored. Increased heart rate at encoding was associated with fewer incorrect responses. In contrast, increased heart rate at retrieval was associated with poorer memory, but only when the interviewer was nonsupportive. Heart rate was unrelated to memory when the interviewer was supportive. Results suggest that arousal at encoding and retrieval have different implications for children's memory for a mild stressor, particularly in nonsupportive interview contexts.

Mental Reinstatement of Context: Do individual differences in mental time travel and eyewitness occupation influence eyewitness performance over different delay intervals?

The Cognitive Interview is a memory‐enhancing interview protocol designed to optimise the access and retrieval of eyewitness memories. Its Mental Reinstatement of Context (MRC) component requires interviewees to mentally reconstruct the crime event they witnessed. Individual differences in mental time travel (MTT) relate to the extent to which a person mentally re‐experiences personal events from his or her past. Individual differences in MTT have been found to predict correct recall of a simulated crime event under immediate MRC recall conditions. To explore the relationship between MTT and performance under MRC conditions further, the present study presented a simulated crime video to 30 police officers and 26 members of the public. Eyewitness recall was tested under MRC conditions either immediately or 1 week later. Participants' general MTT and also MTT relating specifically to the crime video itself were measured via self‐report. Less correct information and more confabulations were produced after 1 week, but delay had no effect on the amount of incorrect information reported. No difference in recall was found between police officers and members of the public. Better quality MTT relating to the crime video was found to be a positive predictor of the amount of information correctly recalled under immediate conditions but not after 1 week. General MTT scores did not predict correct recall under either delay condition. Interviewers need to be aware that, due to individual differences, some witnesses may perform better under the MRC component than others.     

Reducing the Misinformation Effect Through Initial Testing: Take Two Tests and Recall Me in the Morning?

Initial retrieval of an event can reduce people's susceptibility to misinformation. We explored whether protective effects of initial testing could be obtained on final free recall and source‐monitoring tests. After studying six household scenes (e.g., a bathroom), participants attempted to recall items from the scenes zero, one, or two times. Immediately or after a 48‐hour delay, non‐presented items (e.g., soap and toothbrush) were exposed zero, one, or four times through a social contagion manipulation in which participants reviewed sets of recall tests ostensibly provided by other participants. A protective effect of testing emerged on a final free recall test following the delay and on a final source‐memory test regardless of delay. Taking two initial tests did not increase these protective effects. Determining whether initial testing will have protective (versus harmful) effects on memory has important practical implications for interviewing eyewitnesses. © 2015 The Authors.

Repeated partial eyewitness questioning causes confidence inflation but not retrieval‐induced forgetting

During a crime investigation eyewitnesses are often interviewed more than once. Repeated post‐event questioning offers an opportunity for retrieval practice. Practicing retrieval of a subset of memories may suppress access to related memories, a phenomenon known as retrieval‐induced forgetting. In this short report we investigated the generalization of retrieval‐induced forgetting to episodic eyewitness memory of a complex event. The results indicated that repeated retrieval improves future recall of practiced information, but does not induce forgetting of related information. Retrieval practice, however, did result in higher confidence ratings, both for correct and incorrect answers. The practical consequence of this study is that repeated questioning should be avoided if possible. Not because it may induce retrieval‐induced forgetting, but because it may lead to confidence inflation. Copyright © 2008 John Wiley & Sons, Ltd.     

Incurious motives to seek information about potential threats

In Study 1, 20 incurious worry reduction motive (IWRM) items were administered to 280 participants along with curiosity and worry scales. With factor analysis, two six‐item scales were developed: focus on distress (IWRM‐FD) and focus on relief (IWRM‐FR). IWRM‐FD was associated with wanting positive news about threats, whereas IWRM‐FR was related to wanting negative news to be free from further worry. Neither the curiosity nor worry scales predicted wanting information. In Study 2, the IWRM scales were administered to 170 participants along with a coping inventory. IWRM‐FD correlated with avoidant‐coping, whereas IWRM‐FR was associated positively with active‐coping and advice‐seeking. The results suggest that IWRM‐FD reflects a desire to minimize distress, whereas IWRM‐FR motivates identifying and dealing directly with problems. Copyright © 2010 John Wiley & Sons, Ltd.     

Eliciting Intelligence Using the Scharff‐Technique: Closing in on the Confirmation/Disconfirmation‐Tactic

The current study examined interview techniques aimed at eliciting intelligence from human sources. We compared two versions of the Scharff‐technique to the Direct Approach (a combination of open and direct questions). The Scharff conditions, conceptualised into four tactics, differed only with respect to the ‘confirmation/disconfirmation‐tactic’. The participants (N = 90) received background information and took the role as a source in a phone interview. They were instructed to strike a balance between not revealing too little and too much information. As predicted, the Scharff‐technique resulted in more new information than the Direct Approach. Importantly, the sources interviewed by the Scharff‐technique perceived that they had revealed less new information than they objectively did, whereas the sources interviewed by the Direct Approach perceived that they had revealed more new information than they objectively did. Furthermore, the interviewer's information objectives were better masked with the confirmation‐tactic than with the disconfirmation‐tactic. The results highlight the Scharff‐technique as a promising human intelligence gathering technique. Copyright © 2014 John Wiley & Sons, Ltd.     

More Inaccurate But Not More Biased: Anxiety During Encoding Impairs Face Recognition Accuracy But Does Not Moderate the Own‐Ethnicity Bias

Heightened state anxiety can have a deleterious impact on memory for faces. In this paper we investigated whether anxiety: (i) moderates the own‐ethnicity bias (OEB) and (ii) impairs face recognition accuracy at the encoding or retrieval phase of an OEB face‐recognition task. Using a typical OEB task, anxiety was induced during encoding and retrieval in Experiment 1, but only during retrieval in Experiment 2. An OEB was found in both experiments, but anxiety did not moderate the OEB in either experiment. In Experiment 1, anxious participants were poorer at face recognition for both own‐ and other‐ethnicity faces. In Experiment 2 anxiety did not impair face recognition. Together, these studies suggest that anxiety impaired participants' encoding, but not retrieval, of faces. The implications of these findings are discussed. Copyright © 2015 John Wiley & Sons, Ltd.
