Flashbulb and first-hand memories for campus closings due to COVID-19: consistency and change

ABSTRACT Flashbulb memories (FBM) refer to the vivid and detailed retrieval of the reception context of a highly salient event. We examined FBMs and personal memories for one college’s sudden transition to remote learning due to COVID-19. We explored whether the announcement of the campus’ closure resulted in FBMs, how respondents felt about the decision, and the impacts of the decision. Employing a two-wave longitudinal survey conducted in March and May 2020, participants responded to questions regarding learning about the campus’ closure and a control memory (an event from the same week chosen by participants). Participant reports suggested they did form FBMs, and FBMs were more consistent over time than control memories. Confidence did not differ across memory types. Additionally, we observed an initial strong positive response to the decision to close the campus – a sentiment that intensified over time. Lastly, participants’ emotional responses transitioned from negative feelings in the first wave of testing to more neutral feelings in the second. This work offers a unique exploration of FBMs within the broader context of a global health crisis that intruded into daily life, effectively merging the typically public and distant nature of flashbulb events with first-hand, personal experience.

A review of longitudinal studies on flashbulb memories. Where we started, are, and are going?

AbstractSince Brown and Kulik (1977) coined the term ‘Flashbulb memories’ (FBMs), there are still heated debates about their nature. We thus considered it useful to take stock of almost 50 years of research by reviewing 57 test–retest studies on FBMs for public events. The review aimed to answer six research questions by examining the target events and populations investigated (RQ1); the methods used to assess differences among groups and the effect of time on memory (RQ2); the assessment of FBMs' contents (RQ3), consistency (RQ4), vividness and confidence (RQ5); the criteria used to draw studies' conclusions (RQ6). Results show a huge methodological heterogeneity which may have contributed to the different conclusions about the special status of FBMs. The in‐depth comparison of 9/11 studies suggests that results may differ depending on the methods used. Finally, the paper provides methodological suggestions for future FBMs studies and seeks to stimulate critical theoretical reflections.

Flashbulb memories and memories for personal events: Their role in social categorization and identification.

Flashbulb memories and memories for personal events: Their role in social categorization and identification.

Collective memories and social roles: the case of the Paris terrorist attacks of 13 November 2015.

The present study was based on empirical data collected during the first phase (2016) of Study 1000, part of the 13-November Program: a corpus of 934 individual interviews conducted 6-11 months after the events. To process this empirical material, the authors used integrated TXM software, which provides several classic textometry tools. They mainly used the lexical specificity analysis tool, which statistically measures the irregularity of the word distribution according to the parts of the corpus. They also analyzed the concordances of certain very specific lexical forms. Analysis revealed the important influence of social roles on the construction of memories and narratives of this event. Application of textometry tools highlighted lexical fields specific to the different social roles played by the interviewees in this social drama, and showed that it was through these specific vocabularies that they remembered and recounted this extraordinary story. Social roles therefore influence the formation of memories both individual and collective, by modulating the way in which individuals select what to remember and what to forget. The article opens up several interesting avenues for future analyses, mainly a longitudinal perspective (including phases 2 and 3 of Study 1000) for the study of flashbulb memories and the gender issue to fine-tune the analysis of social roles.

Paradoxical boosting of weak and strong spatial memories by hippocampal dopamine uncaging.

The ability to remember changes in the surroundings is fundamental for daily life. It has been proposed that novel events producing dopamine release in the hippocampal CA1 region could modulate spatial memory formation. However, the role of hippocampal dopamine increase on weak or strong spatial memories remains unclear. We show that male mice exploring two objects located in a familiar environment for 5 minutes created a short-term memory (weak) that cannot be retrieved one day later, whereas 10 minutes exploration created a long-term memory (strong) that can be retrieved one day later. Remarkably, hippocampal dopamine elevation during the encoding of weak object location memories (OLMs) allowed their retrieval one day later but dopamine elevation during the encoding of strong OLMs promoted the preference for a familiar object location over a novel object location after 24 hours. Moreover, dopamine uncaging after the encoding of OLMs did not have effect on weak memories whereas on strong memories diminished the exploration of the novel object location. Additionally, hippocampal dopamine elevation during the retrieval of OLMs did not allow the recovery of weak memories and did not affect the retrieval of strong memory traces. Finally, dopamine elevation increased hippocampal theta oscillations, indicating that dopamine promotes the recurrent activation of specific groups of neurons. Our experiments demonstrate that hippocampal dopaminergic modulation during the encoding of OLMs depends on memory strength indicating that hyperdopaminergic levels that enhance weak experiences could compromise the normal storage of strong memories.Significance statement Increased levels of dopamine have been related to cognitive enhancement. Hippocampal dopamine elevation caused by novelty exposure has been proposed as a strategy to enhance memory based on the observation that surprising events create flashbulb memories that are remembered for long time. However, hyperdopaminergic levels could also underlie maladaptive memories, such as non-desired preservation of traumatic experiences. Our experiments show that dopamine elevation in the dorsal hippocampus during the encoding of spatial memories has paradoxical effects, while the enhancement of weak memories allows their retrieval, the dopaminergic modulation of strong memories limits the ability to modify preexisting spatial memories by changes in the environment. We conclude that cognitive enhancement through dopamine boosting must consider diverse aspects of memory formation.

The days we never forget: Flashbulb memories across the life span in Alzheimer’s disease

Alzheimer’s disease (AD) is characterized by autobiographical memory deficits, with the ability to retrieve episodic-rich memories being particularly affected. Here, we investigated the influence of AD on a specific subtype of episodic memories known as flashbulb memories (i.e., the ability to remember the personal circumstances for the reception of important news events). We examined the frequency, characteristics, and the temporal distribution of flashbulb memories across the life span. To this aim, 28 older adults diagnosed with AD and a matched sample of 29 healthy older controls were probed for flashbulb memories for two historical events from each decade of their lives. They also estimated the subjective degree of reexperiencing for the memories reported. AD participants showed impaired access to flashbulb memories, the frequency of reported memories being lower than for healthy older adults. However, qualitative aspects of AD participants’ flashbulb memories were quite similar to those of the controls, as no group differences were obtained with respect to the canonical categories or degree of reexperience. AD participants’ flashbulb memories clustered during the early years of their life, consistent with a reminiscence bump, whereas healthy controls also reported memories dated to later lifetime periods. Our results suggest that probing for personal memories of important public events may serve as a powerful cue for detailed episodic memories in AD.

Emotion language use in narratives of the 9/11 attacks predicts long-term memory.

Despite considerable cognitive neuroscience research demonstrating that emotions can influence the encoding and consolidation of memory, research has failed to demonstrate a relationship between self-reported ratings of emotions collected soon after a traumatic event and memory for the event over time. This secondary analysis of data from a multisite longitudinal study of memories of the September 11, 2001 terrorist attacks, asked the question of whether emotional language use could predict memory over time. In the 2 weeks following the 9/11 attacks, participants (N = 691; Mage = 36.8; 72% identifying as male; 76% identifying as white) wrote narratives about how they learned of the attacks and the impact of the attacks on them. Language features of these narratives were extracted using the Linguistic Inquiry Word Count program and used to predict three types of memory: (a) event memory accuracy, (b) flashbulb memory consistency, and (c) emotion memory consistency. These outcomes were assessed at the time of writing, 1, 3, and 10 years after the 9/11 attacks. Results of linear mixed-effects models indicate that greater use of negative emotion words in narratives predicts better event memory accuracy 3 and 10 years after the attacks and worse flashbulb memory consistency 10 years after the attacks. However, emotion word use does not predict emotion memory consistency across time. We also examine whether other exploratory linguistic predictors are associated with memory over time. These findings suggest that written language may serve as a potential early indicator of memory over time. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The flashbulb-like nature of memory for the first COVID-19 case and the impact of the emergency. A cross-national survey

ABSTRACT Flashbulb memories (FBMs) refer to vivid and long-lasting autobiographical memories for the circumstances in which people learned of a shocking and consequential public event. A cross-national study across eleven countries aimed to investigate FBM formation following the first COVID-19 case news in each country and test the effect of pandemic-related variables on FBM. Participants had detailed memories of the date and others present when they heard the news, and had partially detailed memories of the place, activity, and news source. China had the highest FBM specificity. All countries considered the COVID-19 emergency as highly significant at both the individual and global level. The Classification and Regression Tree Analysis revealed that FBM specificity might be influenced by participants’ age, subjective severity (assessment of COVID-19 impact in each country and relative to others), residing in an area with stringent COVID-19 protection measures, and expecting the pandemic effects. Hierarchical regression models demonstrated that age and subjective severity negatively predicted FBM specificity, whereas sex, pandemic impact expectedness, and rehearsal showed positive associations in the total sample. Subjective severity negatively affected FBM specificity in Turkey, whereas pandemic impact expectedness positively influenced FBM specificity in China and negatively in Denmark.

Emotional Enhancement of Memory in Alzheimer’s Disease: A Systematic Review

AbstractBackgroundProgressive decline in episodic memory is a hallmark of Alzheimer’s disease (AD). Emotional arousal is known to enhance memory. The amygdala, locus coeruleus, hippocampus, and other regions, are key brain structures involved in the facilitation of memory through emotions. Amygdala‐mediated enhanced encoding of emotionally arousing stimuli or events may improve memory in AD patients, however whether this effect is present in patients with AD remains unclear.MethodA systematic search of the literature was conducted in accordance with PRISMA guidelines to identify relevant literature on emotional enhancement of memory (EEM) in AD. We utilized MEDLINE and PsycInfo. Search terms related to emotional memory and Alzheimer’s were searched as keywords and mapped to medical subject headings.Result1545 studies were screened; 40 were included. Participant age ranged from 64 to 84 years. Sample sizes ranged from 20 to 126. Only 11 of the 40 (27.5%) included brain MRI and evaluation of amygdala volume. 34 studies examined long‐term memory. Results showed that 12 out of 34 studies (35.3%) showed clear EEM for long‐term memory among participant with AD. A further 10 studies (29.4%) found that EEM was influenced by stimuli type, valence of emotion, level of encoding, or intensity of emotion. Yet 12 studies (35.3%) found no effect of EEM in AD. Of the 6 studies that specifically explored flashbulb memories in AD, 3 found no EEM and 3 observed that the effect was content‐dependent, such that personal details were remembered more often than factual details of events.ConclusionStudies which included brain imaging showed that amygdala volume is the strongest predictor of EEM in AD, regardless of level of cognitive impairment. The conflicting literature on EEM in AD reveals the importance of evaluating volumes or networks of brain regions known to be involved in emotional memory processing. AD patients included in these studies likely had varying degrees of atrophy in the amygdala, locus coeruleus, hippocampus and frontal regions involved in modulating emotional memories. However, without confirmation from brain imaging, the integrity of these brain structures cannot be established. Future studies are needed to confirm whether atrophy of important brain regions diminishes EEM in AD.

THE INTERTWINING CRISIS OF PERSONAL AND POLITICAL MEMORY IN THE SELECT NOVELS OF KHALED HOSSEINI

The current paper investigates the parallel vision of personal and the political memory of Afghan’s in the novels of Khaled Hosseini. In his novel The Kite Runner and A Thousand Splendid Suns, war was a game changer. He cooked up the novels with his personal childhood memories and added spices of political memory with a pinch of fictional elements. Focusing on the political disaster and the consequences of war, people of Afghan’s suffers from turmoil of war, sexual harassment, patriarchal society, illegitimate child, extramarital affairs, lack of health center and ethnic culture tension. The trauma deals with the flashbulb memories which demystify and comprehend the various ethoses. The interconnecting issues of the political memory affect the normal life of every afghan in the city which was brilliantly penned by the author in both his novels. This study takes up the concern of logical statements towards the eternal pains of the memory of the ethoses due to the devastating war.

Emotional arousing events as an integral part of understanding flashbulb memories mechanism

In this paper, researchers specializing in emotional arousal are most likely to benefit from studying the formation of FBM. Regarding the three different mechanisms of FBM formation, the key similarities between them, a detailed analysis of emotional arousal memory from a physiological and psychological perspective, and a comparison of the different models built for FBM are presented.

Weak correlations among 13 episodic memory tasks related to the same public event

AbstractIf an individual demonstrates accurate autobiographical memory in one task, will they also demonstrate accurate autobiographical memory in related tasks? Over 18 months, 213 participants completed 13 episodic memory tasks related to the same national referendum. Tasks included false memories for fake news, flashbulb memories, factual memories, memory for emotions, hindsight bias, eyewitness accuracy, susceptibility to leading questions and memory blindness. Although moderate to strong correlations were found over time for the same episodic memory tasks, correlations among differing memory tasks were very weak. Our findings suggest that individuals vary in how well they remember different elements of a public event. We conclude that episodic memory is a multi‐faceted construct and researchers should be slow to generalise from one task to another, even when the two tasks refer to the same public event (e.g., we should not presume that individual differences in event memory will predict false memories for fake news).

Flashbulb Memories in the Communication of the Diagnosis of Visual Impairment: The Effect of Context and Content.

The diagnosis of a child's visual impairment is remembered vividly and intensely by their parents. However, the way in which the diagnosis is communicated may affect the development and persistence of this memory. The aim of this study is to analyze the circumstances in which the first news of the diagnosis of visual impairment in children is given and whether the memory of this event persists over time leading to a flashbulb memory. A longitudinal study was carried out with the participation of 38 mothers. Data were collected on sociodemographics, clinical variables, circumstances surrounding the communication of the diagnosis, and the degree of agreement of the information in the two phases of the research. The diagnosis was, on the whole, given to both parents at the same time, in medical language and with little tact, generally in the office of an ophthalmologist. The mothers would have preferred to have received the news in a different way, and the existence of a flashbulb memory is confirmed, more dependent on the context in which the diagnosis was given and its content than on sociodemographic and clinical factors. The way in which the first news of such a diagnosis is given plays a significant role in how it is remembered. Therefore, an improvement in medical practice regarding the communication of such diagnoses is recommended.

A day that America will remember: flashbulb memory, collective memory, and future thinking for the capitol riots

ABSTRACT This study explores the topics of flashbulb memory, collective identity, future thinking, and shared representations for a public event. We assessed the memories of the Capitol Riots, which happened in Washington DC, on 6 January 2021. Seventy Belgian and seventy-nine American citizens participated in an online study, in which they freely recalled the unfolding of Capitol Riots and answered questions regarding their memory. Inter-subjects similarity of recalled details was analysed using a schematic narrative template (i.e., the event, the causes and the consequences). Results revealed that representations of the event, and its causes were more similar among Belgians compared to Americans, whereas Americans’ representations of the consequences showed more similarity than Belgians’. Also, as expected, Americans reported more flashbulb memories (FBMs) than Belgians. The analysis underlined the importance of rehearsal through media and communication in FBM formation. This research revealed a novel relation between FBM and future representations. Regardless of national identity, participants who formed an FBM were more likely to think that the event would be remembered in the future, that the government should memorialise the event, and that a similar attack on the Capitol could happen in the future compared to participants who did not form FBM.

Memory footprint: Predictors of flashbulb and event memories of the 2016 Euro Cup final.

Two years after Portugal won the UEFA European Championship, we examined what the Portuguese remember of this momentous occasion. We investigated if flashbulb memories (FBMs) and event memories (EMs) were determined by distinct factors, and whether EM was a predictor of FBM. Participants responded to an online questionnaire about their FBM, EM and set of predictors. Structural equation modeling revealed that FBM and EM were associated with different pathways. Interest in football predicted importance which triggered emotional intensity which predicted personal rehearsal, a direct determinant of FBMs. On the other pathway, interest determined knowledge about football, the main predictor of EMs. Importantly, EM was a causal determinant of FBM which shows that the memory trace for the original event enhances memory for the reception context. The findings suggests that even though the two types of memories are determined by independent factors, they interact very closely.

“I remember the attack”: a pilot study investigating flashbulb memory in individuals with schizophrenia

Flashbulb memories are autobiographical memories for important and emotional events, which have the particularity of being at the intersection of personal and public events. Autobiographical memory impairments are highly prevalent in schizophrenia, a psychiatric condition intrinsically linked to self-disorders. Thus, we aimed to evaluate flashbulb and event memory functioning in individuals with schizophrenia. Twenty-four individuals diagnosed with schizophrenia and 25 control participants were tested on a flashbulb memory questionnaire about the July 14th, 2016, Nice (France) terrorist attack, including questions on flashbulb and event memory, certainty, vividness, rehearsal, emotion, novelty, consequentiality, implication, and importance. Participants also underwent cognitive assessments. Analysis showed lower scores for both flashbulb and event memories in patients compared to control participants. Subjective ratings of the phenomenological characteristics of flashbulb memory were similar between the two groups overall. However, individuals with schizophrenia reported having higher levels of emotion when they first learned about the attack compared to the control group. Our results replicate findings of impaired autobiographical memory functioning in schizophrenia and extend these findings to public events. Our findings also indicate that flashbulb memories may lead to substantial contextual recall in schizophrenia patients and that collective memories, such as a terrorist attack, can have a profound emotional impact on patients.

THE EFFECT OF MEMORY MODELS ON STUDENTS' LEARNING ABILITY

Abstract. The purpose of this study was to analyze cognitive memory models in humans. This research uses literature study method. The results and conclusions obtained from this study are that memory is a complex and varied phenomenon, with memory it will make an individual’s life feel sustainable, which means humans can relate what happened in the past with the conditions experienced now. Memory has several stages, namely encoding, storage, and recall. With music therapy in post-traumatic amnesia patients the abilities that a person has and do not require conscious processing. The way implicit memory works is by recalling information related to an event or an object that affects actions and thoughts that are carried out unconsciously. Memory itself has several types of models such as sensory memory, short-term memory, long-term memory, implicit memory, explicit memory, and flashbulb memory. With learning about various memory models, it is hoped that individuals will understand more and increase knowledge about memory and remembering. Keywords: memory model, memory, cognitive, remembering, mnemonic method.

The era of our lives: The memory of Korsakoff patients for the first Covid-19 pandemic lockdown in the Netherlands

Memories for worldwide and emotional events (such as 9/11) are more vividly relived and recalled than memories for everyday events. Previous studies have shown that flashbulb memories of a single event enhanced the memory strength in severe amnesia. It is currently unknown whether macro-events that stretch out over longer periods of time (weeks, months) strengthen memory even further. Our aim was therefore to investigate to what extent patients with severe amnesia, due to Korsakoff’s syndrome (KS), were able to relive the first Covid-19 lockdown in the Netherlands, and whether experienced emotions enhanced reliving of the participants. We included 22 KS patients and 24 age-, education-, and gender-matched healthy controls. Covid-19 related memories were assessed by measures of autobiographical memory specificity, phenomenological reliving, emotional intensity and semantic-and episodic knowledge about the first lockdown in March 2020 – May 2020 in the Netherlands. Although amnesia patients remembered significantly fewer autobiographical details regarding the Covid-19 lockdown than healthy controls, one fourth of the KS patients recalled specific events. Amnesia patients reported levels of emotional intensity equivalent to those in the control group. Stronger autobiographical reliving was associated with higher emotional intensity. Both amnesia patients and healthy controls had higher recall of episodic than semantic lockdown related information. In conclusion, results demonstrate that information for macro-events can still be memorized and relived, most specifically when emotional valence is high, even by highly amnestic patients.

Exploring the role of digital media dependency on the relationship between personal involvement and flashbulb memory during the pandemic: Empirical evidence from Mainland China.

Flashbulb memory (FBM) is viewed as a special type of autobiographical memory due to its richness of individuals' self-related details when hearing the news and the long duration. It also helps shape people's impression of public events to some extent. Given that personal involvement is one of the important antecedent variables of FBM, this study proposed to investigate it from spatiotemporal involvement (spatiotemporal distance) and empathic involvement (empathy level) to explore the impact of personal involvement on the formation of FBM during the Covid-19 pandemic. In particular, digital media dependency was considered in the influence of involvement on the FBM since it is a crucial information source for individuals and a path to spread information about their lives and work during the pandemic. In this study, a total of 546 valid questionnaires (from May 1, 2022, to May 7, 2022) and 349 valid questionnaires (from May 10, 2022, to May 17, 2022) were collected through a two-stage online survey in Shanghai, China towards the epidemic wave at the end of March 2022. The mediating mode of digital media dependency was also examined on personal involvement in FBM performance, which consists of FBM specificity, confidence, and consistency. Results showed that empathic involvement had a significant negative influence on FBM specificity, namely the higher the empathy level was, the worse the FBM specificity would be, in which digital media dependency played a suppressing effect. Individuals' spatiotemporal involvement was proved to have a significant positive influence on FBM specificity and consistency. It was one of the first to investigate the FBM formation process around "small peak" events in the context of the ongoing pandemic. Innovatively, empathy was adopted as the index of memory arousal for empathic involvement, and digital media dependency was considered an important mediator variable in the memory study. The research results have practical significance for promoting the process of epidemic recovery integrated with digital media and can provide a social reference for the shaping process of disaster memory from the perspective of digital information and emotional transmission.

Flashbulb memories

Abstract The two authors – one from literary and cultural studies, the other a cognitive psychologist – explore how the interdisciplinary perspective of Memory Studies can broaden and enrich current research efforts on flashbulb memories (FBMs). FBMs are memories of the circumstances in which one learned of a public emotionally charged event, such as 9/11. Psychological research on FBMs have focused on their cognitive properties, their putative accuracy and confidence. But we claim that when seen in the broader interdisciplinary perspective of collective memory research, FBMs emerge as inextricably linked up with social, cultural, and narrative dynamics. This article therefore locates FBMs at the intersection of individual and collective memory narratives. Connecting research in cognitive psychology with cultural Memory Studies, we explore how flashbulb narratives bear on social identity and how they might travel across national boundaries or across generations. We further discuss how FBMs are tied to culture, aesthetics, and media history.
