Denials in informal co‐witness conversations do not affect memory for witnessed events

AbstractCampus sexual assault constitutes a frequent crime witnessed by many. Among co‐witnesses such assault is oftentimes denied. We examined how false denials during an informal co‐witness conversation impacted memory for the conversation and witnessed assault. Ninety participants watched a trauma‐analogue video with a co‐witness. The next day, honest control dyads engaged in an honest, informal discussion about the film. In lying dyads one participant falsely denied (internal false denial group) details during this informal discussion with their co‐witness (external denial group). One week later, participants' recognition memory for the video and conversation was tested. We did not replicate denial‐induced forgetting in that participants who falsely denied did not forget details of the previous conversation, relative to honest participants. Moreover, memory for the film was not statistically significantly affected by our manipulation. Thus, informal false denials might not negatively affect memory, despite previous research showing such effects in formal settings.

Discernment of Children's True and False Memory Reports: Police Officers and Laypersons.

Adults' ability to accurately evaluate children's statements can have far-reaching consequences within the legal system. This study examined the evaluations of police officers ("experts") and laypersons ("nonexperts") when presented with videotaped interviews of children aged 3 and 5 years who provided either true or false reports or denials. Participants were drawn from several counties in the eastern United States. Children's interview statements fell within four statement types: accurate reports, false reports, accurate denials, and false denials. Both groups of participants displayed overbelief in false denials. Several control variables predicted accuracy, including children's age and children's race. A significant interaction emerged: Experts (vs. nonexperts) had greater odds of being accurate when judging false reports (vs. false denials). These findings highlight the challenges adults face when distinguishing between various types of children's statements. The results have important implications for legal contexts, emphasizing that fact finders need to be mindful of the risks associated with both overaccepting false denials and accepting false reports.

External and internal influences yield similar memory effects: the role of deception and suggestion.

In legal cases, testimonies can become contaminated because of an amalgam of external and internal influences on memory. It is well-established that external influences (e.g., suggestive interviews) can hurt memory. However, less focus has been placed on the impact of internal influences (e.g., lying) on memory. In the current review, we show that the available evidence suggests that both external and internal influences exert similar effects on memory. That is, we review studies showing that suggesting non-occurrences and suggesting non-experiences can lead to omission errors and false memories, respectively. Likewise, these memory effects are also observed when focusing on internal influences. That is, false denials, feigning amnesia and fabrication have been shown to affect memory in terms of forgetting (i.e., omissions) and false memories (i.e., commissions). Also, we show that both external and internal influences can lead to changes in the belief that an event occurred. We argue that in legal cases, triers of fact should concentrate on whether both types of influences might have affected testimonial accuracy in witnesses, victims, and suspects.

Introducing the APOD: Analysis of patterns of denial among males accused of sexual offending

Sex offenders have great incentive to deny and/or minimize their offense, and both researchers and treatment providers regularly encounter their socially desirable response patterns. Despite the importance of distinguishing those who are lying about their innocence from those who are truly not culpable, law enforcement agencies and clinicians have few resources, other than the polygraph, to discern false denial from truthful, actual denial using scientifically supported methods. The Analysis of Patterns of Denial (APOD), a checklist of denial techniques, was developed to assist in making this distinction. It was developed by comparing a sample of guilty persons who denied their offense conduct with persons who were falsely accused (i.e., accused and investigated but later convincingly cleared by polygraph, a DNA non-match, and/or confession by another person). Items that satisfactorily discriminated between the two groups were retained in the final checklist. The APOD is intended to help those who work with sex offenders identify denial response patterns to more accurately determine if an alleged sex offender is being truthful or deceptive.

‘Nothing happened’: Legal implications of false denials among abused children

AbstractPeople lie on a frequent basis. However, when a victim of maltreatment lies by denying the abuse, lies can become forensically relevant. We have reviewed the relevant literature on the prevalence and memory consequences of such false denials. The way forensic interviewers proceed in the face of denying children will be shaped by their beliefs about the frequency with which truly abused children deny abuse. We discuss that estimates of the prevalence of false denials among abused children vary but that such false denials do happen. When falsely denying children eventually come forward with their experiences, a second issue lingers: how valid are maltreated children's statements after a false denial? We review the literature indicating that false denials can negatively affect memory for the investigative interview during which the lie was told. Yet, memory for the denied experience itself seems to be mostly preserved, and some research even found potential protective effects of false denials. We conclude that denials should always be handled with care in the court room, since the ground truth usually is not known, but that statements should not be dismissed based solely on previous denials.

False denials increase false memories for trauma-related discussions

ABSTRACT False denials are sometimes used to cope with traumatic experiences. We examined whether false denials can affect true and false memory production for a traumatic event and conversations surrounding the trauma. One hundred and twenty-six participants watched a trauma analogue video of a car crash before being randomly asked in a discussion with the experimenter to (1) respond honestly or (2) falsely deny that certain details happened in the video. After one week, all participants received misinformation about the discussion with the experimenter and the car crash. Finally, all participants were instructed to respond truthfully in a source memory task. Participants who falsely denied information during the first session were statistically significantly more prone than honest participants to omit details they denied and to report misinformation about what was discussed in the first session. Our work suggests that false denials of a traumatic experience might lead to both forgetting and increased false memory levels for earlier conversations about the event.

Can false denials turn fact into fiction? The effect of false denials on memory for self-performed actions

We examined the mnemonic effects of falsely denying a self-performed action. Specifically, participants (N = 30) performed, imagined, or received no instruction about 24 action statements (e.g., “cross your arms”). Next, their memory for whether they had performed, imagined, or did nothing (i.e., received no instructions) with these actions was tested. Subsequently, participants were instructed to repeatedly deny an action they had performed (false denial) and to repeatedly claim to have performed an action they had only imagined (false admission). In a final sorting memory task, 54% (n = 16) of participants erroneously indicated, after false admissions, that they had performed the imagined action. None of the participants indicated that they had only imagined an action after false denials, showing that it might be difficult to forget a performed action, even after repeatedly denying it. The current experiment sets the stage for future research to investigate why it seems to be difficult to forget performed actions.

How Often and Why Do Guilty and Innocent Suspects Confess, Deny, or Remain Silent in Police Interviews?

This study examines how often and why suspects who have reported being either guilty or innocent remain silent, confess, or deny accusations in police interview situations. Convicted offenders under current probation or parole in Germany (N = 280) completed a questionnaire about their perceptions of up to six specific police interview situations they had experienced in their lifetime. As predicted, more suspects reported having confessed truthfully (64.3%) compared to falsely (4.1%) at least once in their lifetime; and more suspects reported having remained silent in guilty interview situations (58.4%) compared to innocent interview situations (18.4%). Unexpectedly, approximately an equal number of suspects reported having denied truthfully (39.8%) and falsely (40.2%) at least once in their lifetime. The main reasons reported for these statement types were that evidence seemed to indicate guilt (true confessions), suspects desired to end the uncomfortable interview situation or protect the real perpetrator/another person (false confessions), evidence seemed weak (false denials), suspects felt innocent (true denials), they desired to protect themselves (silence while being interviewed when guilty), and they followed their attorneys’ advice (silence while being interviewed when innocent). Findings are discussed in the context of the police and psychological research and practice.

Simulating denial increases false memory rates for abuse unrelated information.

Victims of abuse might deny their traumatic experiences. We studied mnemonic effects of simulating false denial of a child sexual abuse narrative. Participants (N = 127) read and empathized with the main character of this narrative. Next, half were instructed to falsely deny abuse‐related information while others responded honestly in an interview. One week later, participants received misinformation for the narrative and interview. In a final source memory task, participants' memory for the narrative and interview was tested. Participants who falsely denied abuse‐related information endorsed more abuse‐unrelated misinformation about the event than honest participants. Abuse‐related false memory rates did not statistically differ between the groups, and false denials were not related to omission errors about (1) the interview and (2) narrative. Hence, victim's memory for abuse‐related information related to their experience might not be affected by a false denial, and inconsistencies surrounding the abuse‐unrelated information are more likely to take place.

Intrusion detection and mitigation of attacks in microgrid using enhanced deep belief network

ABSTRACT The convergence from the electric grid to the smart microgrid motivates the incorporation of the intrusion detection system to identify intruders and mitigate the resultant damages to ensure system stability. It is planned to employ the Deep Belief Network (DBN), which is one of the deep learning techniques with some improvement to detect the attacks in a microgrid. To improve the accuracy of the detection, a rule-based detection technique is added to enhance the detection of intruders using DBN. The proposed technique is supported with the layered micro-grid architecture that makes the system flexible and simple toward the implementation. The proposed Enhanced DBN (EDBN) performance is measured in different bus representations for identifying the higher hit rate and rejection rate, lesser miss rate and false-positive rate. Two attacks, such as False Data Injection and Denial of Service attacks, are generated by Greedy Algorithm and are detected by the proposed technique. Compared to the existing detection and control system, the proposed EDBN technique provides accuracy higher than 92%, false alarm rate less than 1%. Thus, the experimental results show that the proposed technique accuracy is higher than the existing intrusion detection techniques in a microgrid.

Involvement Modulates the Effects of Deception on Memory in Daily Life.

Previous studies have demonstrated that liars who adopt a false denial strategy often forget what they lied about, which has been labeled the denial-induced forgetting (DIF) effect. However, several investigations have not found such an effect. It has been suggested that involvement might play a role in the inconsistency. The present study was designed to directly determine whether involvement modulates the effects of deception on memory. Participants were assigned randomly to either high- or low-involvement conditions and were required to complete a mock shopping task. They were then asked to participate in an interview in which they were asked to respond honestly or deceptively. Two days later, final memory tests were given, and the participants were asked to give honest responses. We found a DIF effect in the high-involvement condition but not in the low-involvement condition. Moreover, the liars in the high-involvement condition created more non-believed memories in the source memory test and the destination memory test than the honest participants. In addition, liars in both the high- and low-involvement conditions forgot who they lied to. We conclude that the effects of deception on memory could be influenced by the degree of involvement.

Public beliefs on the relationship between lying and memory

ABSTRACT In two studies, we surveyed the beliefs of undergraduate students (Study 1) and the general public (Study 2) about deceptive behavior, memory functioning, and the effects of lying on memory. We compared participants’ beliefs with the current memory and deception literature. Overall, participants in both studies believed that different types of lies (i.e. false denials, feigning amnesia, fabrication) would elicit different memory impairing effects, although they did not know what specific kind of memory impairment (e.g. forgetting, false memory). In line with previous experimental studies, participants experienced difficulties in retrieving memories after falsely denying or feigning amnesia. Moreover, participants believed that lying would impact other people’s memory such as that people would start to believe in their own lies. Meanwhile, they also indicated that these effects would be minimal for themselves. Interestingly, our results showed that false denials are used quite frequently in daily life. Finally, we found that undergraduate students’ beliefs about memory were in line with scientific evidence, while the general public continues to have erroneous beliefs about memory. When the general public plays a role in the courtroom (e.g. jury members), we recommend involving memory experts in the assessment of reliability of statements when lying was involved.

Artificial Intelligence for a Reduction of False Denials in Refugee Claims

AbstractDeciding refugee claims is a paradigm case of an inherently uncertain judgment and prediction exercise. Yet refugee status decision-makers may underestimate the uncertainty inherent in their decisions. A feature of recent advances in artificial intelligence (AI) is the ability to make uncertainty visible. By making clear to refugee status decision-makers how uncertain their predictions are, AI and related statistical tools could help to reduce their confidence in their conclusions. Currently, this would only hurt claimants, since many countries around the world have designed their refugee status determination systems using inductive inference which distorts risk assessment. Increasing uncertainty would therefore contribute to mistaken rejections. If, however, international refugee law was to recognize an obligation under the UN Convention to resolve decision-making doubt in the claimant’s favour and use abductive inference, as Evans Cameron has advocated, then by making uncertainty visible, AI could help reduce the number of wrong denied claims.

The role of executive functions in the effects of lying on memory

Recent studies have demonstrated that lying can affect memory and that such memory effects are based on the cognitive load required in performing the lie. The present study aimed to verify whether the impact of two deceptive strategies (i.e., false denials and fabrication) depends on individuals' cognitive resources in terms of Executive Functions (i.e., EF: Shifting, Inhibition, and Updating). A sample of 147 participants watched a video of a robbery and then were instructed to either fabricate (i.e., fabrication condition), deny (i.e. false denial condition), or tell the truth (i.e., truth-telling condition) to some questions about the crime. Two days later, all participants had to provide an honest account on a final memory test where they indicated their memory for having discussed details (i.e., fabricated, denied, or told the truth) and their memory for the video. Finally, their EF resources were also assessed. Our findings demonstrated that individual differences in EFs played a role in how the event was recalled and on the effects of lying on memory. That is, memory for the event after having lied depended especially on individuals' Shifting resources. We also found that the two deceptive strategies differentially affected individuals' memory for the interview and for the event: Denying affected memory for the interview while fabricating affected memory for the event. Our findings can inform legal professionals on the possibility to assess individuals' EF as an indicator of witnesses' credibility.

What can we remember after complex denials? The impact of different false denials on memory

ABSTRACT False denial is a deceptive strategy that requires fewer cognitive resources than other strategies (e.g. simulating amnesia, fabrication). In the present experiment, we examined the effects of different types of false denials varying in cognitive load on memory. Participants (N = 159) watched a video (theft) and then answered some questions about it. Some participants had to tell the truth about the theft, while others were either asked to falsely deny all the event-related details (i.e. simple false denial) or to falsely deny just some details of the same event (i.e. complex false denial). After two days, all participants completed a memory task in which they truthfully recognized whether details were (i) discussed during the interview or (ii) seen in the video. Additionally, recall scores (i.e. correct details, omissions, commissions) of the memory for the event were assessed. Participants who falsely denied all details reported a higher memory impairment for the interview than the other groups. Interestingly, liars who were engaged in complex denying had the largest memory impairment for the event and reported more commissions than those in the simple false denial group. This experiment shows that under certain conditions, memory is increasingly impaired for high cognitive load lies.

Detecting children's true and false denials of wrongdoing: Effects of question type and base rate knowledge.

One common and unfortunately overlooked obstacle to the detection of sexual abuse is non-disclosure by children. Non-disclosure in forensic interviews may be expressed via concealment in response to recall questions or via active denials in response to recognition (e.g., yes/no) questions. In two studies, we evaluated whether adults' ability to discern true and false denials of wrongdoing by children varied as a function of the types of interview question the children were asked. Results suggest that adults are not good at detecting deceptive denials of wrongdoing by children, even when the adults view children narrate their experiences in response to recall questions rather than provide one word answers to recognition questions. In Study 1, adults exhibited a consistent "truth bias," leading them toward believing children, regardless of whether the children's denials were true or false. In Study 2, adults were given base-rate information about the occurrence of true and false denials (50% of each). The information eliminated the adults' truth bias but did not improve their overall detection accuracy, which still hovered near chance. Adults did, however, perceive children's denials as slightly more credible when they emerged in response to recall rather than recognition questions, especially when children were honestly denying wrongdoing. Results suggest the need for caution when evaluating adults' judgments of children's veracity when the children fail to disclose abuse.

THE PHENOMENON OF LIES IN DOMESTIC AND FOREIGN PSYCHOLOGY

Background. The paper presents the results of analysis of the lie category research carried out in the XX–XXI centuries by domestic and foreign scientists. Many authors note that lying as a psychological phenomenon has been studied inconsistently and rather fragmentarily. The diversity of existing definitions of lies emphasizes the complexity of this phenomenon and indicates its insufficient theoretical elaboration, as well as the need to form a holistic, scientifically based understanding of the psychological nature of lies. Aim. The paper presents a comparative analysis of domestic and foreign research on the phenomenon of lies carried out in the XXI century. Results. It has been established that in the XX century researchers ceased to study the moral side of lies giving preference to its formal and dynamic features. In the XXI century, foreign experts describe the mechanism of cognitive distortion and control, as well as verbal and non-verbal signs of deception. The psychological portrait of a liar, the phenomenon of false memories, the role of responsibility, volitional qualities and behavioral attributes in the recognition of lies are being actively studied using a polygraph. Domestic science clarifies the phenomenology of lies, its psychological and psychophysiological mechanisms and pays particular attention to the subjective truth of the liar’s memories. Conclusion. An essential feature of domestic studies on the psychology of lies in the 21st century is the focus on elucidating its psychological mechanisms based on the phenomena of subjective construction of memories, false memories and false denial.

When “Fake News” Becomes Real: The Consequences of False Government Denials in an Authoritarian Country

Governments around the world, particularly authoritarian ones, often deny inconvenient or unfavorable information, calling it fake news or false rumor, and yet what was denied often turns out to be true eventually. How will citizens react when the initial “fake news” is verified to be real? What are the consequences of false government denials on government credibility and citizen satisfaction? Using a survey experiment in China and a follow-up survey, we find that citizens can be persuaded by the authorities’ denials and reduce their belief in a piece of news that has been declared “fake.” But when the denied news turns out to be real, citizens will reduce their belief not only in the denial at hand but also in a similar denial in the future and reduce their satisfaction with the government. Thus, false denials have both immediate and lasting effects on government credibility and can erode citizen satisfaction with the government.

The impact of false denials on forgetting and false memory

People sometimes falsely deny having experienced an event. In the current experiments, we examined the effect of false denials on forgetting and false memory formation. In Experiment 1, participants were presented with emotionally-negative and neutral associatively related word lists known to engender false memories. After encoding, half of the participants had to falsely deny having seen the words while the other half had to tell the truth. During a final memory test (recall or source monitoring task), participants who falsely denied forgot that they discussed certain words with an experimenter. Furthermore, the act of falsely denying reduced the formation of false memories. These results were partially replicated in Experiment 2 where participants also had to re-learn several words and received a second memory task. This latter design feature diminished the effect of false denials on false memory creation. Our experiments suggest that false denials not only have negative consequences (forgetting), but can have positive ones too (reduction in false memories).
