"That never happened": adults' discernment of children's true and false memory reports

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.

Childhood Sexual Abuse: A Longitudinal Study of Disclosures and Denials

In legal cases regarding child sexual abuse (CSA), children have various options, such as to disclose or deny maltreatment. When interviewed in adulthood, their accounts may be consistent with their childhood responses. Alternatively, denial in childhood could be followed in adulthood by disclosure ("deferred disclosure"), confirming previous suspicions. Or the adults could possibly recant. We conducted a longitudinal study of CSA disclosures and denials (N = 99; Time 1 [T1], 3- to 16-year-olds). T1 CSA disclosures and denials at a forensic unit were compared to the individuals' responses 20 years later (Time 2 [T2]. 22- to 37-years-old). We found that consistent disclosure was associated with being older at T1 and female. Deferred disclosure was significantly associated with greater T2 trauma-related symptoms. Corroboration and higher CSA severity predicted T2 recantation. Consistent denial was related to less severe CSA. Our findings add to knowledge about CSA disclosures, which affect legal pathways available to child victims.

Research on the Effects of Lying on Memory: A Scientometric Analysis and a Call for New Studies

Research on the effects of lying and memory is increasingly attracting empirical attention. In the current manuscript, a scientometric analysis was carried out on the mnemonic consequences of lying. This analysis took into account 70 published articles extracted from Scopus and Web of Science databases from 1998 to 2021. A scientometric analysis was conducted in order to visualize the state of the art on this line of research (i.e., authors, countries, institutions, journals, and co-citations). Additionally, a keywords’ cluster analysis was executed to investigate the main keywords used in the published papers. Based on the keywords’ cluster analysis, we identified the main aims and critical issues of the reviewed papers. The United States and the Netherlands are the two most productive countries into the effects of lying on memory. The top five authors are mainly from European countries and wrote from 6 to 15 articles. The cluster analysis detected three clusters of keywords. The critical issues of this line of research are mainly related to the generalizability of the achieved findings for real situations, a lack of a direct control of the manipulation adopted, and a need of additional measures. The current analysis provides a comprehensive overview and understanding of existing research on the effects of lying on memory and provides possible future directions of this research domain.

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.

"I Didn't Do That!" Event Valence and Child Age Influence Adults' Discernment of Preschoolers' True and False Statements

Justice can hinge on adults' abilities to distinguish accurate from inaccurate child testimony. Yet relatively little is known about factors that affect adults' abilities to determine the accuracy of children's eyewitness reports. In this study, adults (N = 108) viewed videoclips of 3- and 5-year-olds answering open-ended and leading questions about positive and negative actually experienced ("true") events or never experienced ("false") events that the children either affirmed or denied. Analyses revealed that adults were more accurate at determining the veracity of negative compared with positive incidents, particularly when children said that they had experienced the event. Moreover, adults' accuracy was at chance for older children's false denials. Psycholegal implications are discussed.

Effects of the putative confession instruction on perceptions of children's true and false statements

The putative confession (PC) instruction (i.e., "[suspect] told me everything that happened and wants you to tell the truth") during forensic interviews with children has been shown to increase the accuracy of children's statements, but it is unclear whether adults' perceptions are sensitive to this salutary effect. The present study examined how adults perceive children's true and false responses to the PC instruction. Participants (n = 299) watched videotaped interviews of children and rated the child's credibility and the truthfulness of his/her statements. When viewing children's responses to the PC instruction, true and false statements were rated as equally credible, and there was a decrease in accuracy for identifying false denials as lies. These findings suggest that participants viewed the PC instruction as truth-inducing. Implications for the forensic use of the PC instruction are discussed.

Explaining gender differences in jurors' reactions to child sexual assault cases

In three experiments, we investigated the influence of juror, victim, and case factors on mock jurors' decisions in several types of child sexual assault cases (incest, day care, stranger abduction, and teacher-perpetrated abuse). We also validated and tested the ability of several scales measuring empathy for child victims, children's believability, and opposition to adult/child sex, to mediate the effect of jurors' gender on case judgments. Supporting a theoretical model derived from research on the perceived credibility of adult rape victims, women compared to men were more empathic toward child victims, more opposed to adult/child sex, more pro-women, and more inclined to believe children generally. In turn, women (versus men) made more pro-victim judgments in hypothetical abuse cases; that is, attitudes and empathy generally mediated this juror gender effect that is pervasive in this literature. The experiments also revealed that strength of case evidence is a powerful factor in determining judgments, and that teen victims (14 years old) are blamed more for sexual abuse than are younger children (5 years old), but that perceptions of 5 and 10 year olds are largely similar. Our last experiment illustrated that our findings of mediation generalize to a community member sample.

The development of differential mnemonic effects of false denials and forced confabulations

The current experiment was designed to assess the mnemonic consequences of false denials and forced confabulations. Children (aged 6-8 and 10-12 years) and adults viewed a video and then their memory and belief about the event were tested. Participants were then divided into three groups. In the "cued recall" condition, participants were asked to answer true- and false-event questions, but could choose not to respond if they did not know the answer. In the "forced confabulation" group, participants received the same set of questions, but were forced to answer all of them. In the "false denial" group, participants were instructed to falsely deny in response to each question. One week later, participants received a source memory test, and they had to provide memory and belief ratings once more. Forced confabulations resulted in false memories in the youngest group. Moreover, our analyses showed that repeated false denials led children and adults to be highly inclined to falsely deny that they had talked to the experimenter about certain presented details, when in fact they had done so. Furthermore, false denial and non-believed memory rates were more pronounced in younger than in older children and adults. Our results imply that denying experienced events is not a good strategy in an interviewing setting, as it adversely affects memory statements about the interview.
