Retrieval-Induced Forgetting in the Feigning Amnesia for a Crime Paradigm

Previous studies demonstrated that, when asked to honestly provide information about a mock crime, former feigners performed worse than those who were requested to confess to this event. Thus, feigning amnesia for a mock crime undermined genuine memory for the same experience. In the present study, we examined whether retrieval-induced forgetting (RIF) underlies this memory-undermining effect. After watching a mock crime, participants had to feign amnesia or confess to having committed that crime. Feigners were given retrieval practice instructions (i.e., retrieval-practice group) or no further instructions (i.e., control group). Immediately and 1 day later, all participants had to genuinely report what they remembered about the crime. Although simulators in the retrieval-practice group recalled the largest amount of information as a positive consequence of retrieval, the ratio for crucial crime-related details was lower than that exhibited by both simulators who were given no instructions and confessors. These findings suggest that RIF might play a role in forgetting critical information in claims of crime-related amnesia. Theoretical and practical implications will be discussed

Believing in dissociative amnesia relates to claiming it:a survey of people's experiences and beliefs about dissociative amnesia

Dissociative amnesia is one of the most controversial categories in the field of psychiatry and clinical psychology. Self-reports of dissociative amnesia in the general population, and beliefs about this topic, have so far not been subjected to empirical scrutiny. Here, we surveyed a sample from the general population (N = 1017), revealing that about a tenth (n = 102) claimed to have experienced dissociative amnesia. Some claims pertained to amnesia for traumatic autobiographical experiences (e.g., sexual assault), while other claims reflected memory loss for experiences that can be regarded as non-traumatic or non-stressful (e.g., dissociative amnesia for an anniversary). Importantly, many participants believed in the existence of dissociative amnesia, and those who claimed dissociative amnesia indicated even more belief in this phenomenon than the rest of the sample. Finally, many participants indicated to have at least once claimed to have feigned memory loss in their life, and that they experienced some form of forgetting when trying to retrieve events for which they lied upon. Overall, our findings suggest that claiming dissociative amnesia goes hand in hand with believing in dissociative amnesia

A Critical Review of Case Studies on Dissociative Amnesia

Dissociative amnesia, defined as an inability to remember important autobiographical experiences, usually of a stressful nature, is a controversial phenomenon. We systematically reviewed 128 case studies of dissociative amnesia reported in 60 articles that appeared in peer-reviewed journals in English over the past 20 years (2000-2020). Our aim was to examine to what extent these cases met core features of dissociative amnesia. All cases were about reports of autobiographical memory loss, but the evidence offered in support of a dissociative amnesia interpretation was often weak and plagued by an ambiguous heterogeneity with respect to nature, etiology, and differential diagnoses of alleged memory loss. Most case studies failed to rule out plausible alternative explanations of dissociative amnesia, such as ordinary forgetting and malingering. We encourage clinicians and researchers to more critically investigate alleged cases of dissociative amnesia and provide criteria for how a dissociative amnesia case ideally would look like.</p

An experimental investigation of the misinformation effect in crime-related amnesia claims

Research suggests that both internal (i.e., lying) and external (i.e., misinformation) factors can affect memory for a crime. We aimed to explore the effects of post‐event misinformation on crime‐related amnesia claims. We showed participants a mock crime and asked them to either simulate amnesia (simulators) or confess to it (confessors). Next, some participants were provided with misinformation. Finally, all participants were requested to genuinely recollect the crime. Overall, simulators reported less correct information than confessors. Moreover, these two groups were equally vulnerable to misinformation. In addition, exploratory analyses on strategies adopted by simulators revealed that those who previously, mostly omitted information while simulating amnesia exhibited the lowest amount of correct details. Simulators who instead used a mixed strategy disclosed more fabricated memory errors. Findings suggest that legal professionals and jurors should take into account that even offenders, irrespective of confessing or simulating memory loss for a crime, can be susceptible to post‐event misinformation

Feigning Amnesia Moderately Impairs Memory for a Mock Crime Video

Previous studies showed that feigning amnesia for a crime impairs actual memory for the target event. Lack of rehearsal has been proposed as an explanation for this memory-undermining effect of feigning. The aim of the present study was to replicate and extend previous research adopting a mock crime video instead of a narrative story. We showed participants a video of a violent crime. Next, they were requested to imagine that they had committed this offense and to either feign amnesia or confess the crime. A third condition was included: Participants in the delayed test-only control condition did not receive any instruction. On subsequent recall tests, participants in all three conditions were instructed to report as much information as possible about the offense. On the free recall test, feigning amnesia impaired memory for the video clip, but participants who were asked to feign crime-related amnesia outperformed controls. However, no differences between simulators and confessors were found on both correct cued recollection or on distortion and commission rates. We also explored whether inner speech might modulate memory for the crime. Inner speech traits were not found to be related to the simulating amnesia effect. Theoretical and practical implications of our results are discussed

Do reminders of the crime reverse the memory-undermining effect of simulating amnesia?

Research shows that simulating amnesia impairs actual memory for a mock crime. Lack of rehearsal has been suggested as the most likely explanation for this finding because feigning amnesia is linked to reduced thinking about the offence. We investigated whether reminders about the crime could reverse the memory-undermining effect of simulation. In two studies, participants watched a video of a violent crime. After, they were asked to either simulate amnesia or confess the crime. During the week between the first and second memory test phase, participants were provided with reminders of the crime in two different modalities. In Study 1 (pilot), participants received frames of the mock crime video via WhatsApp. Findings showed that such reminders did not enhance ex-simulators’ memory. In Study 2, participants were asked to put sequences of the mock crime in the right order. This latter modality led to enhanced memory for the offence in simulating participants. Theoretical and practical implications of our findings for the legal field are discussed

Can implicit measures detect source information in crime-related amnesia?

Participants who are asked to simulate amnesia for a mock crime have a weaker memory for this event when they have to give up their role as a feigner, than those who are not asked to feign memory loss. According to the source monitoring framework (SMF), this memory-undermining effect of simulating amnesia for a crime would be due to misattribution of the right source of information. However, we know that the content of self-generated information (e.g., feigned version of the crime) might be preserved and recognised over time as a result of elaborative cognitive processing. In the present study, we aimed to contrast these two explanations. We showed participants a mock crime video and we instructed them to either feign amnesia (simulators) or confess the mock crime (confessors). Next, a free recall memory test was administered. After one week, participants were asked to perform a personalised source monitoring task using the autobiographical Implicit Association Test (aIAT). As predicted, we found that simulators were able to discriminate the content of their self-generated feigned story of the crime from the original version. Moreover, simulators were quicker than confessors at the aIAT task. Practical and theoretical implications of our results are discussed

Leo Weiczen Valiani: Fiuman, European, Revolutionary, Historian. Special Issue of the West Croatian History Journal (10).

In 2015 the Faculty of Humanities and Social Sciences of the University of Rijeka hosted the international conference From Leo Weiczen to Leo Valiani. The aim of the conference was to present and discuss the work and life of an intellectual of European calibre, born and raised in Rijeka, where he started his antifascist activism. Weiczen/Valiani continued his revolutionary activism in the following years of internment and imprisonment in Italy, and as political émigré in France, Spain and Mexico. During World War II he became a prominent leader of the partisan movement in Italy, therefore a member of the Constituent Assembly of Italian Republic. Having abandoned his political career, he became a proficient historian and newspaper commentator. President Sandro Pertini proclaimed him senator for life of the Italian Republic. He was also honorary President of the Società di studi fiumani in Rome The idea of this conference dates 2014. The Departments of History and Italian Studies of the Faculty of Humanities and Social Sciences shared the organization of this conference, wholeheartedly supported by two faculty managements. The City of Rijeka also promoted this event, which was inserted by the Italian Consulate in the manifestation Weeks of Italian Culture in Rijeka. The conference hosted an exhibition on Leo Valiani/Weiczen and his family imbedded in the Rijeka Jewish network with documentation from the State Archive in Rijeka. The curators of the exhibition were Ivan Jeličić and Lea Čeč, who were helped by the students of the “Liceo” (Rijeka’s Italian high school). The exhibition was open to the public after the conference in the hall of the Faculty of Humanities and Social Sciences. This special issue of the journal of the Department of History (the West Croatian History Journal) selected some of the papers of the conference, modified by authors into scholarly articles and peer reviewed before being accepted. In the second part of this publication you will find some additional works, including the catalogue of the exhibition, which will hep the reader to get a more comprehensive picture of the various aspects of the life and work of Leo Weiczen/Valiani, from his “fiuman” environment, to his experiences as European intellectual and revolutionary, and as respected historian of Austria- Hungary

Can Lung Imaging Scores and Clinical Variables Predict Severe Course and Fatal Outcome in COVID-19 Pneumonia Patients? A Single-Center Observational Study

COVID-19 prediction models mostly consist of combined clinical features, laboratory parameters, and, less often, chest X-ray (CXR) findings. Our main goal was to propose a prediction model involving imaging methods, specifically ultrasound. This was a single-center, retrospective cohort observational study of patients admitted to the University Hospital Split from November 2020 to May 2021. Imaging protocols were based on the assessment of 14 lung zones for both lung ultrasound (LUS) and computed tomography (CT), correlated to a CXR score assessing 6 lung zones. Prediction models for the necessity of mechanical ventilation (MV) or a lethal outcome were developed by combining imaging, biometric, and biochemical parameters. A total of 255 patients with COVID-19 pneumonia were included in the study. Four independent predictors were added to the regression model for the necessity of MV: LUS score, day of the illness, leukocyte count, and cardiovascular disease (&chi;2 = 29.16, p &lt; 0.001). The model accurately classified 89.9% of cases. For the lethal outcome, only two independent predictors contributed to the regression model: LUS score and patient&rsquo;s age (&chi;2 = 48.56, p &lt; 0.001, 93.2% correctly classified). The predictive model identified four key parameters at patient admission which could predict an adverse outcome
