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

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.

On pattern completion, cues and future-oriented cognition.

Barzykowski and Moulin's view on involuntary autobiographical memory focuses on automatic activation of representations and inhibitory control mechanisms. We discuss how and when a known neural mechanism - pattern completion - may result in involuntary autobiographical memories, the types of cues that may elicit this phenomenon and consider interactions with future-oriented cognition.

Collective remembering and future forecasting during the COVID-19 pandemic: How the impact of COVID-19 affected the themes and phenomenology of global and national memories across 15 countries.

The COVID-19 pandemic created a unique set of circumstances in which to investigate collective memory and future simulations of events reported during the onset of a potentially historic event. Between early April and late June 2020, we asked over 4,000 individuals from 15 countries across four continents to report on remarkable (a) national and (b) global events that (i) had happened since the first cases of COVID-19 were reported, and (ii) they expected to happen in the future. Whereas themes of infections, lockdown, and politics dominated global and national past events in most countries, themes of economy, a second wave, and lockdown dominated future events. The themes and phenomenological characteristics of the events differed based on contextual group factors. First, across all conditions, the event themes differed to a small yet significant degree depending on the severity of the pandemic and stringency of governmental response at the national level. Second, participants reported national events as less negative and more vivid than global events, and group differences in emotional valence were largest for future events. This research demonstrates that even during the early stages of the pandemic, themes relating to its onset and course were shared across many countries, thus providing preliminary evidence for the emergence of collective memories of this event as it was occurring. Current findings provide a profile of past and future collective events from the early stages of the ongoing pandemic, and factors accounting for the consistencies and differences in event representations across 15 countries are discussed.

The reciprocal relationship between episodic memory and future thinking: How the outcome of predictions is subsequently remembered.

Evidence suggests that memory is involved in making simulations and predictions about the future (i.e., future thinking), but less work has examined how the outcome of those predictions (whether events play out as predicted or expected) subsequently affects episodic memory. In this investigation, we examine whether memory is better for outcomes that are consistent with predictions, or whether memory is enhanced for outcomes that are inconsistent with predictions, after the predicted event occurs. In this experiment, participants learned a core trait associated with social targets (e.g., high in extroversion), before making predictions about behaviors targets would perform. Participants then were shown behaviors the social targets actually performed (i.e., prediction outcome), which was either consistent or inconsistent with predictions. After that, participants completed a memory test (recognition; recall) for the prediction outcomes. For recognition, the results revealed better memory for outcomes that were consistent with traits associated with targets (i.e., trait-consistent outcomes), compared to outcomes that were inconsistent (i.e., trait-inconsistent outcomes). Finding a memory advantage for trait-consistent outcomes suggests that outcomes that are in line with the contents of memory (e.g., what one knows; schemas) are more readily remembered than those that are inconsistent with memory, which may reflect an adaptive memory process. For recall, memory did not differ between trait-consistent and trait-inconsistent outcomes. Altogether, the results of this experiment advance understanding of the reciprocal relationship between episodic memory and future thinking and show that outcome of predictions has an influence on subsequent episodic memory, at least as measured by recognition.

The good old days and the bad old days: evidence for a valence-based dissociation between personal and public memory.

How does memory for the public past differ from memory for the personal past? Across five experiments (N = 457), we found that memories of the personal past were characterised by a positivity bias, whereas memories of the public past were characterised by a negativity bias. This valence-based dissociation emerged regardless of how far back participants recounted the personal and public past, whether or not participants were asked to think about significant events, how much time participants were given to retrieve relevant personal and public memories, and also generalised across various demographic categories, including gender, age, and political affiliation. Along with recent work demonstrating a similar dissociation in the context of future thinking, our findings suggest that personal and public event cognition fundamentally differ in terms of access to emotionally salient events. Direct comparisons between personal and public event memory should represent a fruitful avenue for research on event cognition.

Age-related changes in repetition suppression of neural activity during emotional future simulation.

Despite advances in understanding the consequences of age-related episodic memory decline for future simulation, much remains unknown regarding changes in the neural underpinnings of future thinking with age. We used a repetition suppression paradigm to explore age-related changes in the neural correlates of emotional future simulation. Younger and older adults simulated positive, negative, and neutral future events either 2 or 5 times. Reductions in neural activity for events simulated 5 versus 2 times (i.e., repetition suppression) identify brain regions responsive to the specific emotion of simulated events. Critically, older adults showed greater repetition suppression than younger adults in the temporal pole for negative simulations, and the cuneus for positive simulations. These findings suggest that older adults distance themselves from negative future possibilities by thinking about them in a more semantic way, consistent with the view that older adults down-regulate negative affect and up-regulate positive affect. More broadly this study increases our understanding of the impact of aging on the neural underpinnings of episodic future simulation.

Future thinking about social targets: The influence of prediction outcome on memory.

Work on future thinking suggests that people use what they know about the world (e.g., contents of memory) to make predictions about events to come, which reflects an adaptive use of memory. Less work, however, has examined whether the outcomes of these predictions-whether the outcome is consistent or inconsistent with predictions-influences memory. In two experiments, participants learned trait information about social targets and used that information to predict which of two behaviors social targets would be most likely to engage in: one behavior consistent with previously learned trait information about the target and the other behavior inconsistent. Participants then learned which behavior the social target actually performed (outcome) and then judged whether or not they expected that outcome (expectancy). Across both studies, prediction-consistent outcomes were better remembered than inconsistent ones, suggesting that participants relied on their existing representations of social targets when making memory judgments rather than incorporating inconsistent information into memory. Further, there was a memory advantage for prediction-inconsistent outcomes, but only when participants subjectively rated these outcomes as unexpected. Overall, these findings extend understanding of future thinking and suggest a reliable memory advantage for outcomes that are consistent with predictions.

A negativity bias in detail generation during event simulation.

Novel negative events are simulated in more event-specific detail than novel positive events. In the present study, we set out to assess whether this negative event detail bias is specific to simulations of personal events or whether evoking negative valence, in the context of simulations of personal and nonpersonal events, is sufficient for boosting simulated event detail. Participants simulated novel negative and positive events that might take place in their future, the future of an acquaintance, or the future of a familiar individual with whom they have not had prior contact. Across 2 experiments, we found that novel negative events were simulated in more event-specific detail than novel positive events irrespective of whether the events under consideration were personal or nonpersonal. This pattern of results also emerged when negative and positive events did not differ on a subjective measure of arousal, indicating that negative valence may play a key role in encouraging detailed elaboration of novel negative events. Implications of our findings for the role of event simulation in adaptive behavior are discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Staying positive in a dystopian future: A novel dissociation between personal and collective cognition.

The future of groups of people is a topic of broad interest in society and academia. Nonetheless, relatively little is known about the manner in which people think about the collective future of groups, and whether personal and collective future thinking represent distinct domains of future-oriented cognition. In the present studies (N = 691), we used an adapted future fluency task to demonstrate a novel domain-by-valence interaction between personal and collective future thinking, such that U.S.-based participants were positively biased about their personal future while at the same time being negatively biased about the future of their country. We further present evidence that this valence-based dissociation extends into the distant future, emerges in a non-U.S. (Canadian) sample, depends on the individual's relation to the group, and has consequences for how people think about the world around them. Taken together, our findings represent the first behavioral evidence of a dissociation between personal and collective future thinking, and suggest that the study of collective future thinking represents a fruitful endeavor for psychological science.

Beyond communication: Episodic memory is key to the self in time.

Mahr & Csibra (M&C) propose that episodic memory evolved to support epistemic authority in social communication. We argue for a more parsimonious interpretation whereby episodic memory subserves a broader preparatory function for both social and non-social behavior. We conclude by highlighting that functional accounts of episodic memory may need to consider the complex interrelations between self and subjective time.

Remembering and imagining alternative versions of the personal past.

Although autobiographical memory and episodic simulations recruit similar core brain regions, episodic simulations engage additional neural recruitment in the frontoparietal control network due to greater demands on constructive processes. However, previous functional neuroimaging studies showing differences in remembering and episodic simulation have focused on veridical retrieval of past experiences, and thus have not fully considered how retrieving the past in different ways from how it was originally experienced may also place similar demands on constructive processes. Here we examined how alternative versions of the past are constructed when adopting different egocentric perspectives during autobiographical memory retrieval compared to simulating hypothetical events from the personal past that could have occurred, or episodic counterfactual thinking. Participants were asked to generate titles for specific autobiographical memories from the last five years, and then, during functional magnetic resonance (fMRI) scanning, were asked to repeatedly retrieve autobiographical memories or imagine counterfactual events cued by the titles. We used an fMRI adaptation paradigm in order to isolate neural regions that were sensitive to adopting alternative egocentric perspectives and counterfactual simulations of the personal past. The fMRI results revealed that voxels within left posterior inferior parietal and ventrolateral frontal cortices were sensitive to novel visual perspectives and counterfactual simulations. Our findings suggest that the neural regions supporting remembering become more similar to those underlying episodic simulation when we adopt alternative egocentric perspectives of the veridical past.

Episodic Future Thinking: Mechanisms and Functions.

Episodic future thinking refers to the capacity to imagine or simulate experiences that might occur in one's personal future. Cognitive, neuropsychological, and neuroimaging research concerning episodic future thinking has accelerated during recent years. This article discusses research that has delineated cognitive and neural mechanisms that support episodic future thinking as well as the functions that episodic future thinking serves. Studies focused on mechanisms have identified a core brain network that underlies episodic future thinking and have begun to tease apart the relative contributions of particular regions in this network, and the specific cognitive processes that they support. Studies concerned with functions have identified several domains in which episodic future thinking produces performance benefits, including decision making, emotion regulation, prospective memory, and spatial navigation.

Neural activity associated with repetitive simulation of episodic counterfactual thoughts.

When people revisit past autobiographical events they often imagine alternative ways in which such events could have occurred. Often these episodic counterfactual thoughts (eCFT) are momentary and fleeting, but sometimes they are simulated frequently and repeatedly. However, little is known about the neural differences between frequently versus infrequently repeated eCFT. The current study explores this issue. In a three-session study, participants were asked to simulate alternative ways positive, negative, and neutral autobiographical memories could have occurred. Half of these eCFT were repeatedly re-simulated while the other half were not. Immediately after, participants were asked to simulate all these eCFT again while undergoing fMRI. A partial least squares analysis on the resultant fMRI data revealed that eCFT that were not frequently repeated preferentially engaged brain regions including middle (BA 21) and superior temporal gyri (BA 38/39), middle (BA 11) and superior frontal gyri (BA 9), and hippocampus. By contrast, frequently repeated eCFT preferentially engaged regions including medial frontal gyri (BA 10), anterior cingulate cortex, insula, and inferior parietal lobule (BA 40). Direct contrasts for each type of eCFT were also conducted. The results of these analyses suggest differential contributions of regions traditionally associated with eCFT, such as BA 10, anterior cingulate cortex, and hippocampus, as a function of kind of eCFT and frequency of repetition. Consequences for future research on eCFT and rumination are considered.

The devil is in the details: Comparisons of episodic simulations of positive and negative future events.

Over the past decade, psychologists have devoted considerable attention to episodic simulation-the ability to imagine specific hypothetical events. Perhaps one of the most consistent patterns of data to emerge from this literature is that positive simulations of the future are rated as more detailed than negative simulations of the future, a pattern of results that is commonly interpreted as evidence for a positivity bias in future thinking. In the present article, we demonstrate across two experiments that negative future events are consistently simulated in more detail than positive future events when frequency of prior thinking is taken into account as a possible confounding variable and when level of detail associated with simulated events is assessed using an objective scoring criterion. Our findings are interpreted in the context of the mobilization-minimization hypothesis of event cognition that suggests people are especially likely to devote cognitive resources to processing negative scenarios.

Shifting visual perspective during retrieval shapes autobiographical memories.

The dynamic and flexible nature of memories is evident in our ability to adopt multiple visual perspectives. Although autobiographical memories are typically encoded from the visual perspective of our own eyes they can be retrieved from the perspective of an observer looking at our self. Here, we examined the neural mechanisms of shifting visual perspective during long-term memory retrieval and its influence on online and subsequent memories using functional magnetic resonance imaging (fMRI). Participants generated specific autobiographical memories from the last five years and rated their visual perspective. In a separate fMRI session, they were asked to retrieve the memories across three repetitions while maintaining the same visual perspective as their initial rating or by shifting to an alternative perspective. Visual perspective shifting during autobiographical memory retrieval was supported by a linear decrease in neural recruitment across repetitions in the posterior parietal cortices. Additional analyses revealed that the precuneus, in particular, contributed to both online and subsequent changes in the phenomenology of memories. Our findings show that flexibly shifting egocentric perspective during autobiographical memory retrieval is supported by the precuneus, and suggest that this manipulation of mental imagery during retrieval has consequences for how memories are retrieved and later remembered.

Episodic specificity induction impacts activity in a core brain network during construction of imagined future experiences.

Recent behavioral work suggests that an episodic specificity induction-brief training in recollecting the details of a past experience-enhances performance on subsequent tasks that rely on episodic retrieval, including imagining future experiences, solving open-ended problems, and thinking creatively. Despite these far-reaching behavioral effects, nothing is known about the neural processes impacted by an episodic specificity induction. Related neuroimaging work has linked episodic retrieval with a core network of brain regions that supports imagining future experiences. We tested the hypothesis that key structures in this network are influenced by the specificity induction. Participants received the specificity induction or one of two control inductions and then generated future events and semantic object comparisons during fMRI scanning. After receiving the specificity induction compared with the control, participants exhibited significantly more activity in several core network regions during the construction of imagined events over object comparisons, including the left anterior hippocampus, right inferior parietal lobule, right posterior cingulate cortex, and right ventral precuneus. Induction-related differences in the episodic detail of imagined events significantly modulated induction-related differences in the construction of imagined events in the left anterior hippocampus and right inferior parietal lobule. Resting-state functional connectivity analyses with hippocampal and inferior parietal lobule seed regions and the rest of the brain also revealed significantly stronger core network coupling following the specificity induction compared with the control. These findings provide evidence that an episodic specificity induction selectively targets episodic processes that are commonly linked to key core network regions, including the hippocampus.

Interpolated testing influences focused attention and improves integration of information during a video-recorded lecture.

Although learning through a computer interface has become increasingly common, little is known about how to best structure video-recorded lectures to optimize learning. In 2 experiments, we examine changes in focused attention and the ability for students to integrate knowledge learned during a 40-min video-recorded lecture. In Experiment 1, we demonstrate that interpolating a lecture with memory tests (tested group), compared to studying the lecture material for the same amount of time (restudy group), improves overall learning and boosts integration of related information learned both within individual lecture segments and across the entire lecture. Although mind wandering rates between the tested and restudy groups did not differ, mind wandering was more detrimental for final test performance in the restudy group than in the tested group. In Experiment 2, we replicate the findings of Experiment 1, and additionally show that interpolated tests influence the types of thoughts that participants report during the lecture. While the tested group reported more lecture-related thoughts, the restudy group reported more lecture-unrelated thoughts; furthermore, lecture-related thoughts were positively related to final test performance, whereas lecture-unrelated thoughts were negatively related to final test performance. Implications for the use of interpolated testing in video-recorded lectures are discussed. (PsycINFO Database Record

Cognitive approaches to the study of episodic future thinking.

The concept of episodic future thinking--the ability to simulate events that may take place in the personal future--has given rise to an exponentially growing field of research that spans a variety of sub-disciplines within psychology and neuroscience. In this introduction to the special issue, we provide a brief historical overview of factors that have shaped research on the topic and highlight the need for additional behavioural work to uncover cognitive mechanisms that support episodic future thinking and differentiate it from other related modes of future-oriented cognition. We conclude by discussing the manner in which the various contributions to the special issue fill the gaps in our knowledge and make some of our own suggestions for future work.

Visual perspective in remembering and episodic future thought.

According to the constructive episodic simulation hypothesis, remembering and episodic future thinking are supported by a common set of constructive processes. In the present study, we directly addressed this assertion in the context of third-person perspectives that arise during remembering and episodic future thought. Specifically, we examined the frequency with which participants remembered past events or imagined future events from third-person perspectives. We also examined the different viewpoints from which third-person perspective events were remembered or imagined. Although future events were somewhat more likely to be imagined from a third-person perspective, the spatial viewpoint distributions of third-person perspectives characterizing remembered and imagined events were highly similar. These results suggest that a similar constructive mechanism may be at work when people remember events from a perspective that could not have been experienced in the past and when they imagine events from a perspective that could not be experienced in the future. The findings are discussed in terms of their consistency with--and as extensions of--the constructive episodic simulation hypothesis.

Episodic future thinking in generalized anxiety disorder.

Research on future-oriented cognition in generalized anxiety disorder (GAD) has primarily focused on worry, while less is known about the role of episodic future thinking (EFT), an imagery-based cognitive process. To characterize EFT in this disorder, we used the experimental recombination procedure, in which 21 GAD and 19 healthy participants simulated positive, neutral and negative novel future events either once or repeatedly, and rated their phenomenological experience of EFT. Results showed that healthy controls spontaneously generated more detailed EFT over repeated simulations. Both groups found EFT easier to generate after repeated simulations, except when GAD participants simulated positive events. They also perceived higher plausibility of negative-not positive or neutral-future events than did controls. These results demonstrate a negativity bias in GAD individuals' episodic future cognition, and suggest their relative deficit in generating vivid EFT. We discuss implications for the theory and treatment of GAD.
