Perceived event resolution-rather than time-allows older adults to reduce the negativity of their memories.

In addition to showing greater memory positivity soon after negative events, older adults can be more likely than younger adults to show decreases in memory negativity as events grow more distant. We recently showed that this latter effect was not present when adults were asked to rate memories of the initial phase of the COVID-19 pandemic (March-May 2020): after a short (June/July 2020) and long delay (October/November 2020), older age was associated with greater reflections on positive aspects, but with no difference in negative aspects. We suggested that older adults did not show decreased negativity because the pandemic was still prevalent in their daily lives. The present study examines whether perceived event resolution-rather than time on its own-may be necessary to show age-related decreases in negativity by surveying participants during a time when many may have felt like the pandemic had resolved (Summer 2021). Once again, age was associated with increased ratings of the positive aspects, but at this timepoint, age was also associated with decreased ratings of the negative aspects. These results suggest that older adults may more successfully decrease the negativity of their memories compared to younger adults only when they feel that events have resolved.

The effects of daily autobiographical memory training on memory bias, mood and stress resilience in dysphoric individuals.

Negative memory bias refers to the enhanced recall of negative memories and is a prominent cognitive factor causing and maintaining depression. Surprisingly few studies modify this negative recall. The current study used a smartphone-based autobiographical memory training to increase positive memory recall and thereby alter negative memory bias. A total of 96 dysphoric (≥ 13 BDI-II) participants were randomly allocated to a positive, sham or no-training condition, conducted over a period of 6 days. Positive memory bias (i.e., recalled event evaluation) significantly increased from pre- to post-training after positive and sham intervention, suggesting an unspecific training effect. No transfer to memory specificity, implicit memory bias or depressive symptoms was found, nor was the training effect modulated by pre-existing level of positive memory bias. A post-hoc follow-up measurement during the initial COVID-19 crisis revealed that subjects who benefitted most from either of the trainings maintained their stress levels better during a natural stressful period, compared to those who responded least to the training. Future studies should carefully consider the impact of sham training design. Moreover, it is important to examine transfer effects of bias training as practice in daily life.

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.

Immunization with 674-685 fragment of SARS-Cov-2 spike protein induces neuroinflammation and impairs episodic memory of mice.

COVID-19 is accompanied by strong inflammatory reaction and is often followed by long-term cognitive disorders. The fragment 674-685 of SARS-Cov-2 spike protein was shown to interact with α7 nicotinic acetylcholine receptor involved in regulating both inflammatory reactions and cognitive functions. Here we show that mice immunized with the peptide corresponding to 674-685 fragment of SARS-Cov-2 spike protein conjugated to hemocyanin (KLH-674-685) demonstrate decreased level of α7 nicotinic acetylcholine receptors, increased levels of IL-1ß and TNFα in the brain and impairment of episodic memory. Choline injections prevented α7 nicotinic receptor decline and memory loss. Mice injected with immunoglobulins obtained from the blood of (KLH-674-685)-immunized mice also demonstrated episodic memory decline. These data allow suggesting that post-COVID memory impairment in humans is related to SARS-Cov-2 spike protein-specific immune reaction. The mechanisms of such effect are being discussed.

Injurious Memories from the COVID-19 Frontline: The Impact of Episodic Memories of Self- and Other-Potentially Morally Injurious Events on Romanian Nurses' Burnout, Turnover Intentions and Basic Need Satisfaction.

Nurses have been frequently exposed to Potentially Morally Injurious Events (PMIEs) during the COVID-19 pandemic. Due to resource scarcity, they both perpetrated (self-PMIEs) and passively witnessed (other-PMIEs) moral transgressions toward the patients, severely violating their moral values. Our study investigated the impact of self- and other-PMIEs on work outcomes by exploring nurses' episodic memories of these events and the basic psychological need thwarting associated with them. Using a quasi-experimental design, on a convenience sample of 463 Romanian nurses, we found that PMIEs memories were uniquely associated with burnout and turnover intentions, after controlling for socio-demographic characteristics, general basic psychological need satisfaction at work and other phenomenological characteristics. Both self- and other-PMIEs memories were need thwarting, with autonomy and competence mediating their differential impact on burnout, and with relatedness-on turnover intentions. Our findings emphasize the need for organizational moral repair practices, which should include enhancing nurses' feelings of autonomy, relatedness and competence. Psychological counseling and psychotherapy should be provided to nurses to prevent their episodic memories of PMIEs to be (fully) integrated in autobiographical knowledge, because this integration could have severe consequences on their psycho-social function and occupational health, as well as on the organizational climate in healthcare institutions.

The Moral Impact of the COVID-19 Pandemic on Nurses' Burnout, Work Satisfaction and Adaptive Work Performance: The Role of Autobiographical Memories of Potentially Morally Injurious Events and Basic Psychological Needs.

The COVID-19 pandemic resulted in unprecedented exposure to Potentially Morally Injurious Events (PMIEs) for nurses, in which they were both moral transgressors and moral victims, with deleterious consequences on their psycho-social health and functioning. Our experimental design compared memories of PMIEs with memories of severe moral transgressions (SMTs), in which participants were only moral transgressors. Drawing from Self-Determination Theory and research on moral auto-biographical episodic memories, we assessed a conceptual model describing the impact of recalling a single PMIE or SMT event on nurses' burnout, work satisfaction and adaptive performance. Our convenience sample comprised 614 Romanian nurses, and data was analyzed with path analysis, general linear modelling, and t-tests. Findings showed that memories of PMIEs, compared to SMTs, were more autonomy thwarting, being associated with more controlled work motivation, less moral learning, higher burnout, less work satisfaction, and adaptive performance. Burnout, moral learning, and work satisfaction were significant mediators of the relationships between PMIE and SMT recall and, respectively, adaptive performance. Our results highlight the urgency for organizational practices of moral repair for nurses after the pandemic, along with interventions meant to increase their autonomy and self-determined work motivation.

Memory advantage for untrustworthy faces: Replication across lab- and web-based studies.

The Covid-19 pandemic imposed new constraints on empirical research and forced researchers to transfer from traditional laboratory research to the online environment. This study tested the validity of a web-based episodic memory paradigm by comparing participants' memory performance for trustworthy and untrustworthy facial stimuli in a supervised laboratory setting and an unsupervised web setting. Consistent with previous results, we observed enhanced episodic memory for untrustworthy compared to trustworthy faces. Most importantly, this memory bias was comparable in the online and the laboratory experiment, suggesting that web-based procedures are a promising tool for memory research.

The effect of retrieval goals on the content recalled from complex narratives.

Memories are not always accurately recalled, and one factor that influences memory is the goal of retrieval. Evidence suggests that retrieving a memory to fit a social goal affects the content that is recollected, yet the nature of this effect, and whether this effect remains stable over time, is not fully understood. To this end, we compared the effect of retrieving a complex event (i.e., a narrative) motivated by a social versus an accuracy goal both immediately and after a 24-hour consolidation period. Three groups of young adults encoded audio narratives and recalled these narratives immediately (Session 1) and again after a 24-hour delay (Session 2). One group recalled the narratives to meet a social goal across both sessions (social); another group recalled the narratives for an accuracy goal across both sessions (accuracy); and a final group initially recalled the narratives for a social goal (Session 1) and then for an accuracy goal (Session 2; mixed). We found no effect of group on the number of details that described the overall theme (central details); however, a social goal significantly reduced the number of specific (episodic) details and altered the order in which the details were described. When the goal of retrieval changed across session (i.e., mixed group), the reduction in specific details remained but not the effect on detail order. These results demonstrate that socially motivated memory retrieval selectively alters the specific episodic content contained in the memory, leaving intact the thematic knowledge and overall structure of the memory.

Deactivation of prospective memory intentions: Examining the role of the stimulus-response link.

Successful prospective remembering involves formation of a stimulus (e.g., bottle of medication and/or place where the bottle is kept)-response (e.g., taking a medication) link. We investigated the role of this link in the deactivation of no-longer-relevant prospective memory intentions, as evidenced by commission error risk. Experiment 1a contrasted two hypotheses of intention deactivation (degree of fulfillment and response frequency) by holding constant the degree of intention fulfillment (e.g., participants responded to one of two target words) while manipulating the number of times the intention was performed. Findings supported the response frequency hypothesis. Experiment 1b employed novel lure trials to examine what "stimulus" participants link the prospective memory response to-target words and/or the salient contextual cue-and compared commission errors to Experiment 1a. Findings suggested the salient context alone does not always function as the stimulus. Collectively these findings, in conjunction with those of Experiment 2 (a within-experiment replication) and a combined analysis, suggest that (a) intention deactivation is facilitated by prior responding (formation/strengthening of stimulus-response links), but additional research is needed to establish the robustness of this effect, and (b) when responding frequently to targets, participants are more likely to bind the response to the context alone than to the target or target/context combination, possibly because they learn to rely on context to predict target occurrence. The latter finding was robust and indicates that deactivation of the appropriate stimulus (target and/or context)-response link may be a critical component of reducing commission errors.

The possible effects of the COVID-19 pandemic on the contents and organization of autobiographical memory: A Transition-Theory perspective.

The COVID-19 Pandemic is unique in its near universal scope and in the way that it has changed our lives. These facts suggest that it might also be unique in its effects on memory. A framework outlined in this article, Transition Theory, is used to explicate the mnemonically relevant ways in which the onset of the Pandemic differs from other personal and collective transitions and how the Pandemic Period might differ from other personally-defined and historically-defined autobiographical periods. Transition Theory also provides the basis for several predictions. Specifically, it predicts (a) a COVID bump (an increase in availability of event memories at the outset of the Pandemic) followed by (b) a lockdown dip (a decrease in availability of event memories from lockdown periods compared to other stable periods). It also predicts that (c) people may consider the Pandemic an important chapter in their life stories, but only when there is little continuity between their pre-Pandemic and post-Pandemic lives. Time will tell whether these predictions pan out. However, it is not too soon to highlight those aspects of the COVID-19 Pandemic that are likely to shape our personal and collective memories of this very unusual historical period.

Surviving COVID-19: The Neuroscience of Smart Working and Distance Learning.

The persistence of the coronavirus-caused respiratory disease (COVID-19) and the related restrictions to mobility and social interactions are forcing a significant portion of students and workers to reorganize their daily activities to accommodate the needs of distance learning and agile work (smart working). What is the impact of these changes on the bosses/teachers' and workers/students' experience? This article uses recent neuroscience research findings to explore how distance learning and smart working impact the following three pillars that reflect the organization of our brain and are at the core of school and office experiences: (a) the learning/work happens in a dedicated physical place; (b) the learning/work is carried out under the supervision of a boss/professor; and (c) the learning/work is distributed between team members/classmates. For each pillar, we discuss its link with the specific cognitive processes involved and the impact that technology has on their functioning. In particular, the use of videoconferencing affects the functioning of Global Positioning System neurons (neurons that code our navigation behavior), mirror neurons, self-attention networks, spindle cells, and interbrain neural oscillations. These effects have a significant impact on many identity and cognitive processes, including social and professional identity, leadership, intuition, mentoring, and creativity. In conclusion, just moving typical office and learning processes inside a videoconferencing platform, as happened in many contexts during the COVID-19 pandemic, can in the long term erode corporate cultures and school communities. In this view, an effective use of technology requires us to reimagine how work and teaching are done virtually, in creative and bold new ways.

More Vulnerable? The Life Story Approach Highlights Older People's Potential for Strength During the Pandemic.

OBJECTIVES: Older adults have repeatedly been referred to as more physically vulnerable during the COVID-19 pandemic. The pandemic, however, is not only about becoming physically ill. It has many psychosocial aspects: people are exposed to myriad life challenges. The life story approach does not ignore physical status but also emphasizes psychosocial strengths. It highlights that older people are likely to have developed resilience through experiencing life challenges and living across history. METHOD: We used the narrative method to review research on three strengths: tendency toward life reflection, adaptive use of personal memory, and temporal focus encouraging generativity. RESULTS: For each, we (a) present evidence that this strength manifests in the second half of life, and (b) identify how it may specifically be applied in dealing with the challenges of the pandemic. In considering their life stories, the picture that emerges is one of older adults as having the potential to show considerable psychosocial strength despite the adversities of the pandemic. DISCUSSION: We conclude that during this period of sweeping change in the lives of individuals of all ages, our older citizens may act as valuable societal anchors.

Online pharmacy navigation skills are associated with prospective memory in HIV disease.

OBJECTIVE: The increased use of online pharmacy services in the midst of the COVID-19 pandemic provides an important backdrop against which to examine the role of neurocognitive functions in health-related Internet navigation skills among persons with chronic medical conditions, such as HIV disease. Prospective memory (PM) is reliably impaired in HIV disease and is related to laboratory-based measures of medication management capacity in other populations. This study examined whether PM shows veridicality in relationship to online pharmacy navigation skills in persons with HIV disease. METHOD: Participants included 98 persons with HIV disease age 50 and older who completed the Cambridge Prospective Memory Test (CAMPROMPT) and the Medication-Management Test-Revised (MMT-R) as part of a neuropsychological study. Participants also completed the Test of Online Pharmacy Skills (TOPS), which required them to navigate a simulated, experimenter-controlled online pharmacy to perform several naturalistic tasks (e.g., refill an existing prescription). RESULTS: Lower PM had medium associations with poorer MMT-R and TOPS accuracy scores that were not better explained by other neurocognitive functions. The association between PM and TOPS accuracy was driven by errors of omission and did not vary meaningfully based on whether the intention was cued by time or an event. CONCLUSIONS: These data suggest that PM cue detection processes show veridicality with online pharmacy navigation skills. Future studies might examine the benefits of PM-based strategies (e.g., salient prompts) in supporting online health navigation skills in populations that experience clinically impactful PM failures.
