Abstract
Whereas the effects of emotional intensity (the perceived strength of an item's valence or arousal) have long been studied in true- and false-memory research, emotional ambiguity (the uncertainty that attaches to perceived emotional intensity) has only been studied recently. Available evidence suggests that emotional ambiguity has reliable effects on true memory that are distinct from those of emotional intensity. However, those findings are mostly restricted to recall, and the effects of emotional ambiguity on false memory remain unexplored. The current study addressed both limitations by measuring the effects of emotional ambiguity and emotional intensity on true and false recognition. In two experiments, we manipulated valence ambiguity and valence intensity (Experiment 1) and arousal ambiguity and arousal intensity (Experiment 2) of Deese/Roediger/McDermott lists. Multiple linear regression analyses were conducted for Experiment 1, Experiment 2, and the combined data of the experiments to separate the effects of emotional ambiguity and emotional intensity. Our results showed that both valence ambiguity and arousal ambiguity improved true recognition, and the effects of valence ambiguity remained robust even when controlling for valence intensity, arousal intensity, and arousal ambiguity. More importantly, for both valence and arousal, there was an interaction between ambiguity and intensity in false memory. Specifically, we found that valence ambiguity increased false recognition with positive valence, while arousal ambiguity amplified the effect of arousal intensity on false recognition. Our results are discussed in the context of the emotional ambiguity hypothesis and fuzzy-trace theory.

Simulating denial increases false memory rates for abuse unrelated information. BEHAVIORAL SCIENCES & THE LAW 2022; 40:433-451. [PMID: 35194828 PMCID: PMC9543993 DOI: 10.1002/bsl.2566] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 01/20/2022] [Accepted: 01/28/2022] [Indexed: 06/14/2023]
Abstract
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.

The Relationship between Suggestibility, Fabrication, Distortion, and Trauma in Suspected Sexually Abused Children. SOCIAL SCIENCES 2021.

Abstract
Being a victim of abuse in childhood can lead to the development of trauma-related psychopathology, which could affect the testimony of the child victim. Post-traumatic stress disorder (PTSD) is a factor that can increase both the levels of suggestibility and the production of memory errors, such as confabulations, which can be identified in distortions and fabrications. No studies have analyzed the relationship between suggestibility, fabrications, distortions, and PTSD on samples of children and adolescents suspected of being sexually abused. This study aims to verify in a sample of 221 sexually abused children and adolescents the effect of PTSD, measured by Trauma Symptoms Checklist for Children, in increasing the levels of immediate and delayed suggestibility and the production of fabrications and distortions in immediate and delayed memory tasks, obtained by Gudjonsson Suggestibility Scale 2, controlling age and non-verbal intelligence. Our results show that PTSD increases the levels of immediate and delayed suggestibility, but it has no effect on memory recall in immediate recall tasks. Moreover, PTSD leads to a greater number of distorted and fabricated information inserted in delayed memory. Forensic implications of PTSD consequences on memory tasks and suggestibility levels of sexually abused children are discussed.

Abstract
Recalling an event impairs an individual's later ability to recall related knowledge. Impairment in this retrieval-induced forgetting (RIF) produces a dysfunction in autobiographical memory. This, like somatic symptoms, has been documented in trauma and sexual abuse survivors. To investigate the relationship between past trauma and somatoform disorders, and the role of memory recall dysfunction in this relationship, three sex-matched groups were constituted using DSM IV criteria: Somatoform (SD) (n. 22) other Psychiatric Disorders (PD) (n. 26) and Healthy Subjects (HS) (n. 35). Responses to Stressful Life Events Screening Questionnaire revised (SLESQ-R); Direct Forgetting paradigm (DF) for autobiographical memory; Deese-Roediger-McDermott (DRM) paradigm for false memory; Stanford Scale type A for Post-Hypnotic Amnesia (PHA); Stroop Colour Word test and a digit-span for cognitive assessment; and Somatosensory Amplification Scale (SSAS), Somatic Dissociation Questionnaire (SDQ-20), and Toronto Alexithymia Scale (TAS 20) for somatic discomfort were compared among groups. SSAS, SDQ-20 and TAS F1 were correlated with SLESQ-R scores; subjects with higher numbers of traumatic events (NSE) showed greater capacity to remember items-to-be-forgotten (DFF) and higher SDQ-20 scores. Although the SD group showed higher NSE, their autobiographical memory scores were no different to those of other DSM-IV groups. The somatic-trauma-autobiographical memory impairment relationship is identified by DSM V but not DSM IV criteria for somatoform disorder. Higher NSE appears to correlate with both the presence of somatic discomfort and impaired autobiographical memory, suggesting autonoetic consciousness dysfunction in subjects with past trauma and current somatic symptom disorders.

Suggestibility in neglected children: The influence of intelligence, language, and social skills. CHILD ABUSE & NEGLECT 2018; 79:51-60.

Abstract
We administered the GSS-2, a standardised measure of suggestibility, to 5- to 12-year-old children to ascertain whether neglected children's responses to leading questions distinguish them from those of their non-neglected counterparts. Neglected children (n = 75) were more likely than an age-matched sample of non-neglected children (n = 75) to yield to leading questions, despite no difference in their ability to recall the test stimuli. Subsequent collection of individual difference data from the neglected sample revealed that this effect could not be attributed to intelligence, language ability, problem behaviours, age at onset of neglect, or time spent in out-of-home care. With respect to social skill, however, suggestibility was positively correlated with communicative skill, and marginally positively correlated with assertion and engagement. While on the surface our social skills findings seem counter-intuitive, it is possible that maltreated children with relative strengths in these areas have learned to comply with adults in their environment as a way to protect themselves or even foster belonging. Our data, while preliminary, raise interesting questions about whether targeted interventions could help these children to more actively participate in decisions about their lives.

What Drives False Memories in Psychopathology? A Case for Associative Activation. Clin Psychol Sci 2017; 5:1048-1069.

Abstract
In clinical and court settings, it is imperative to know whether posttraumatic stress disorder (PTSD) and depression may make people susceptible to false memories. We conducted a review of the literature on false memory effects in participants with PTSD, a history of trauma, or depression. When emotional associative material was presented to these groups, their levels of false memory were raised relative to those in relevant comparison groups. This difference did not consistently emerge when neutral or nonassociative material was presented. Our conclusion is supported by a quantitative comparison of effect sizes between studies using emotional associative or neutral, nonassociative material. Our review suggests that individuals with PTSD, a history of trauma, or depression are at risk for producing false memories when they are exposed to information that is related to their knowledge base.

Abstract
We tested the effects of repeated testing and feedback on recollection accuracy in first graders, third graders, and adults. All participants studied a list of words and pictures, and then took three recollection tests, with each test probing different words and pictures from the earlier study phase. On the first and third tests no feedback was given, whereas on the second test, some subjects received item-level feedback throughout the recollection test. Recollection confusion scores declined across successive tests in all age groups. However, explicit feedback did not improve recollection accuracy or reduce recollection confusions in any age group. We also found that all age groups were able to use picture recollections in a disqualifying monitoring strategy without task experience or feedback. As a whole, these findings suggest that children and adults can use some aspects of retrieval monitoring without feedback or practice, whereas other aspects of retrieval monitoring can benefit from test practice in children and adults. We discuss the potential roles of metacognitive learning and unintended social feedback on these test practice effects.

The Deese-Roediger-McDermott (DRM) Task: A Simple Cognitive Paradigm to Investigate False Memories in the Laboratory. J Vis Exp 2017:54793.

Abstract
The Deese, Roediger and McDermott (DRM) task is a false memory paradigm in which subjects are presented with lists of semantically related words (e.g., nurse, hospital, etc.) at encoding. After a delay, subjects are asked to recall or recognize these words. In the recognition memory version of the task, subjects are asked whether they remember previously presented words, as well as related (but never presented) critical lure words ('doctor'). Typically, the critical word is recognized with high probability and confidence. This false memory effect has been robustly demonstrated across short (e.g., immediate, 20 min) and long (e.g., 1, 7, 60 d) delays between encoding and memory testing. A strength of using this task to study false memory is its simplicity and short duration. If encoding and retrieval components of the task occur in the same session, the entire task can take as little as 2 - 30 min. However, although the DRM task is widely considered a 'false memory' paradigm, some researchers consider DRM illusions to be based on the activation of semantic memory networks in the brain, and argue that such semantic gist-based false memory errors may actually be useful in some scenarios (e.g., remembering the forest for the trees; remembering that a word list was about "doctors", even though the actual word "doctor" was never presented for study). Remembering the gist of experience (instead of or along with individual details) is arguably an adaptive process and this task has provided a great deal of knowledge about the constructive, adaptive nature of memory. Therefore, researchers should use caution when discussing the overall reach and implications of their experiments when using this task to study 'false memory', as DRM memory errors may not adequately reflect false memories in the real world, such as false memory in eyewitness testimony, or false memories of sexual abuse.

Maltreatment increases spontaneous false memories but decreases suggestion-induced false memories in children. BRITISH JOURNAL OF DEVELOPMENTAL PSYCHOLOGY 2017; 35:376-391.

Abstract
We examined the creation of spontaneous and suggestion‐induced false memories in maltreated and non‐maltreated children. Maltreated and non‐maltreated children were involved in a Deese–Roediger–McDermott false memory paradigm where they studied and remembered negative and neutral word lists. Suggestion‐induced false memories were created using a misinformation procedure during which both maltreated and non‐maltreated children viewed a negative video (i.e., bank robbery) and later received suggestive misinformation concerning the event. Our results showed that maltreated children had higher levels of spontaneous negative false memories but lower levels of suggestion‐induced false memories as compared to non‐maltreated children. Collectively, our study demonstrates that maltreatment both increases and decreases susceptibility to memory illusions depending on the type of false memory being induced. Statement of contribution What is already known on this subject? Trauma affects memory. It is unclear how trauma affects false memory.
What does this study add? This study focuses on two types of false memories.

Abstract
Two experiments were conducted to examine eyewitness memory in children and adolescents (9- to 15-years-old) with and without known histories of maltreatment (e.g., physical abuse, exposure to domestic violence). In Experiment 1, participants (N = 35) viewed a positive film clip depicting a congenial interaction between family members. In Experiment 2, participants (N = 31) watched a negative film clip in which a family argument was shown. Younger age and higher levels of trauma-related psychopathology significantly predicted commission errors to direct questions when the positive family interaction had been viewed, but not when the negative family interaction had been shown. Maltreatment history was not a significant unique predictor of memory performance for the positive or negative film clip. Implications for a scientific understanding of the effects of child maltreatment on memory are discussed.

Abstract
The accuracy and consistency of children's memories of their removals from their biological families by the Child Protective Services (CPS) was investigated. A researcher was present during the removals and documented what happened. A total of 37 maltreated children, aged 3 to 12 years, were interviewed 1 week and 3 months after the removals. The accuracy of the memory reports was high at both time points, but their consistency was fairly low; in all age groups (3-6, 7-10, and 11-12 years), a high percentage of new accurate information was reported during the second interview and a high percentage of the accurate information reported in the first interview was omitted in the second interview. Older children were significantly more consistent in their memory reports than younger children. The results show that low consistency in memory does not imply memory inaccuracy and has implications for the interpretation of successive interviews of children in forensic contexts.

Abstract
The purpose of the present research was to examine Deese-Roediger-McDermott false memory for trauma-related and nontrauma-related lists in adolescents and adults with and without documented histories of child sexual abuse (CSA). Individual differences in psychopathology and adult attachment were also explored. Participants were administered free recall and recognition tests after hearing CSA, negative, neutral, and positive Deese-Roediger-McDermott lists. In free recall, CSA and negative lists produced the most false memory. In sharp contrast, for recognition, CSA lists enjoyed the highest d' scores. CSA-group adolescents who evinced greater posttraumatic stress disorder (PTSD) symptoms had higher rates of false memory compared to (a) non-CSA group adolescents with higher PTSD symptom scores (free recall), and (b) CSA-group adolescents with lower PTSD symptom scores (recognition). Regression analyses revealed that individuals with higher PTSD scores and greater fearful-avoidant attachment tendencies showed less proficient memory monitoring for CSA lists. Implications for trauma and memory development and for translational research are discussed.
