I still think it was a banana:memorable lies and forgettable truths

Interpersonal influences on cognition can distort memory judgements. Two experiments examined the nature of these ‘social’ influences, and whether their persistence is independent of their accuracy. Experiment 1 found that a confederate’s social proximity, as well as the content and the confidence of their utterances, interactively modulate participants’ immediate conformity. Notably, errant confederate statements that ‘lied’ about encoded material had a particularly strong immediate distorting influence on memory judgements. Experiment 2 revealed that these ‘lies’ were also memorable, continuing a day later to impair memory accuracy, while accurate confederate statements failed to produce a corresponding and lasting beneficial effect on memory. These findings suggest that an individual’s ‘informational’ social influence can be selectively heightened when they express misinformation to someone who suspects no deceptive intent. The methods newly introduced here thus allow multiple social and cognitive factors impinging on memory accuracy to be manipulated and examined during realistic, precisely controlled dyadic social interactions

The use of self-disclosure to build rapport with mock covert human intelligence sources (CHIS)

The use of covert human intelligence sources for the protection of national security is an important but under-researched area. In light of increased globalisation, and technological developments, examining covert intelligence gathering online may have operational relevance. This study examined the use of similarities in self disclosure to develop rapport with mock covert human intelligence sources online. A sample of 66 participants were asked to assume the role of a CHIS, listen to an audio recording of a meeting of the criminal network they are part of, and strike a balance between being forthcoming to their handler while at the same time not revealing all information they possessed. They were then interviewed online by a mock handler who opened the conversation in one of three ways: self-disclosing information that highlighted similarities between herself and the CHIS, self disclosing information that highlighted dissimilarities, or control (no disclosure). Participants completed a follow-up rapport questionnaire based on their interaction with the handler. The study found that mock sources rated rapport higher in the similarities condition in comparison with other conditions; however, it did not translate into a significant difference in the intelligence reported. The findings of this research and its policy and practice implications are discussed

A systematic review exploring variables related to bystander intervention in sexual violence contexts

This article presents a systematic review of the available literature which has investigated the role of key variables in facilitating or inhibiting bystander intervention (including direct intervention, tertiary and secondary prevention) in sexual violence (SV) contexts. Studies exploring the role of individual, situational and contextual variables were grouped to provide a narrative overview of bystanders’ personal characteristics as well as the immediate and wider contexts which may be influencing their bystander behaviour. A systematic search of published literature from four electronic databases identified 2526 articles that were screened, of which 85 studies met the inclusion criteria. Most studies focused upon the role of individual variables, in particular gender of bystander. This body of work finds females are more likely to intervene than males; however, not all studies report these differences and in some cases, this is influenced by the type of intervention behaviour being considered. Regarding situational variables, the most commonly researched variable was the presence of other bystanders, although the role of this variable as inhibiting or facilitating was not clear. Finally, the most commonly researched contextual variable was social norms towards intervention, which has consistently shown greater bystander intervention when there is a belief that peers support such behaviour. Very few studies considered the interaction between these variables. Therefore, it is important for future research to consider this gap in the literature so that we can obtain a more well-rounded understanding of variables that can inhibit and facilitate bystander intervention in SV contexts

Facilitators and barriers of bystander intervention: A focus group study with a university sample

Image-based sexual abuse (IBSA) encompasses the taking, sharing, and/or threatening to share nude or sexual images of others without their consent. The prevalence of IBSA is growing rapidly due to technological advancements, such as access to smartphones, that have made engagement in such activities easier. Bystanders offer an important means of intervention, but little is known about what facilitates or inhibits bystander action in these contexts. To address this gap in the literature, seven focus groups (n = 35) were conducted to explore the factors that facilitate and inhibit bystander action in the context of three different IBSA scenarios (taking, sharing, and making threats to share nude or sexual images without consent). Using thematic analysis, eight themes were identified, suggesting that the perceived likelihood of intervention increased with greater feelings of responsibility, empathy with the victim, reduced feelings of audience inhibition, greater feelings of safety, greater anger toward the IBSA behavior, closer relationships with the victim and perpetrator, the incident involving a female victim and male perpetrator, and perception of greater benefits of police involvement. These findings are considered alongside the physical sexual violence literature in highlighting the similarities and nuances across the different contexts. Implications for the development of policies and educational materials are discussed in relation to encouraging greater bystander intervention in IBSA contexts

Evaluation of Forensic Interviews and Interrogations: A Thematic Analysis of Law-Enforcement Views

Purpose. Effective forensic interviewing is crucial, particularly if the interview is the only source of evidence. Whilst there are a number of non-coercive interview models that advocate for reflective practice, the evaluation of interviews rarely gets the time or attention it deserves. This is concerning given that interviewer skills drop significantly after six months, and there are limited opportunities for refresher training. The aims of the current study were to explore how law enforcement officers reflect upon and evaluate their interviews and seek their insight into what they believe an effective evaluation tool would constitute. Methodology. A total of 32 officers from three police forces in England and Wales and six international security organisations completed a qualitative questionnaire that explored their views on how interview evaluation is conducted and the impact on the interview, and how technology could assist in this important stage in terms of usability, efficacy and capability of a new evaluation tool. Findings. Thematic Analysis was utilised resulting in three overall themes emerging from the data. These focused on current evaluation methods, barriers to conducting evaluations and technological solutions. Originality. The findings are discussed in relation to interviewing and the Forensic Interview Trace©. Implications for practice include the need for much more effort to be put into (re) introducing the evaluation stage into training to ensure that officers are allowed to reflect upon and evaluate their interview performance

Exogenous social identity cues differentially affect the dynamic tracking of individual target faces

We report on an experiment to investigate the top-down effect of exogenous social identity cues on a multiple-identity tracking task, a paradigm well suited to investigate the processes of binding identity to spatial locations. Here we simulated an eyewitness event in which dynamic targets, all to be tracked with equal effort, were identified from among a “crowd” of 8 faces, as an assailant, bystander, policeman, and victim. Even in such a simplistic paradigm, where no actual assault was witnessed and no consequences were associated with the task, results demonstrated a significant attentional bias, namely that participants were significantly better at tracking the assailant, bystander, and policeman than they were the victim. We found no difference in accurate recall based on the use of text or face cues and no systematic pattern of response errors

Developing a narrative theory of deception for the analysis of mock-Covert Human Intelligence Source (CHIS) accounts

Human source intelligence (HUMINT) practitioners are concerned with detecting informant deception, and previous research indicates that the verbal content of an informant’s narrative can be used to identify potential deceit. The current study extends previous research by analysing the narrative structure and narrative identity of accounts provided by 22 participants undertaking the role of a mock-informant. Results indicate that deception affects the structure of a mock-informant narrative, with deceptive mock-informants employing abstract introductions and evaluative remarks to withhold information and to distract their listeners with emotional content. Additionally, deceptive mock-informants are more likely to express a low potency narrative role, such as a victim or tragic hero. Furthermore, there is tentative evidence to suggest that an analysis of narrative identity can also provide an indication of varying levels of motivation and cooperation among truthful mock-informants. These findings have implications for HUMINT practitioners in the field and add to the wider body of deception detection research

Self-Generated Cues: The role of cue quality in facilitating eyewitness recall

Purpose: Witness-led techniques, informed by theory, have been recognised as best practice for eliciting information from cooperative eyewitnesses. In the current research, we test a self-generated cue (SGC) mnemonic grounded in memory theory and explore the impact of three SGC mnemonics on subsequent recall performance. Methodology: Participants (N = 170) witnessed a live staged event and reported their recall using a SGC mnemonic (keywords only, event-line, or concept map) or control technique (other-generated cues or free recall only). These mock witness accounts were compared in terms of correct and incorrect details reported. Findings: Fewer correct details were reported in the other-generated cue condition compared to the SGC event-line (p = .018) and SGC concept map (p = .010). There were no significant differences between free recall alone and any other condition. The number of inaccurate details reported did not differ between conditions (p = .153). Our findings suggest that high quality free recall instructions can benefit recall performance above generic cues (e.g. other-generated cues) but using SGCs to support a structured recall (e.g., concept map or event-line) may offer an additional recall benefit. Originality: Our findings support previous research that SGCs benefit recall beyond other-generated cues. However, by comparing different cue generation techniques grounded in the literature, we extend such findings to show that SGC generation techniques are not equally effective and that combining SGCs with structured recall is likely to carry the greatest benefit to recall

What works in investigative interviewing? Using Systematic Maps to examine the evidence base

Competent investigative interviewing skills are key to securing reliable information from victims, witnesses, informants, and suspects. Information obtained in interviews often plays an important role in directing an investigation, informing effective decision-making, promoting efficient allocation of resources, as well as securing reliable prosecutions and mitigating risk of miscarriages of justice. However, effective investigative interviewing is a complex skill to master; demanding a sound understanding of the many cognitive, social, and environmental factors that influence the content and accuracy of witness and suspect accounts. To ensure that investigative interviewing and intelligence gathering produces usable, credible, and reliable information in an effective and ethically defensible manner, training and practice must be evidence-based. This short article outlines how practitioners, trainers and policy makers can navigate the best available research evidence to evaluate ‘what works?’ in investigative interviewing

“Tell me more about this…”: An examination of the efficacy of follow‐up open questions following an initial account

In information gathering interviews, follow-up questions are asked to clarify and extend initial witness accounts. Across two experiments, we examined the efficacy of open-ended questions following an account about a multi-perpetrator event. In Experiment 1, 50 mock witnesses used the timeline technique or a free recall format to provide an initial account. Although follow-up questions elicited new information (18–22% of the total output) across conditions, the response accuracy (60%) was significantly lower than that of the initial account (83%). In Experiment 2 (N = 60), half of the participants received pre-questioning instructions to monitor accuracy when responding to follow-up questions. New information was reported (21–22% of the total output) across conditions, but despite using pre-questioning instructions, response accuracy (75%) was again lower than the spontaneously reported information (87.5%). Follow-up open-ended questions prompt additional reporting; however, practitioners should be cautious to corroborate the accuracy of new reported details
