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.

Collective memories refer to a group's shared representation of the past, which are slow to change over time. In this study, representative samples of American and German Younger Adults (YAs) and Older Adults (OAs) rated the emotional valence of 12 national historic events. Critically, both age groups were also asked to take on the perspective of the other: OAs imagined how YAs feel, whereas YAs imagined how OAs feel about the same events today. The results replicated previous findings that OAs and YAs hold differing opinions on numerous events. Both age groups successfully recognised these different collective perceptions between generations to some extent. Yet, OAs were more accurate in the perspective-taking task, with YAs consistently underestimating the intensity of OAs' emotional valence. Self-reported perspective-taking strategies suggest that OAs relied more on stereotypes and considered education, while knowledge from specific people was universally used to rate the other age group's perspective.

The Emerging Adulthood is a complex and chaotic period and depression is one of the main psychological health problems during this period. Overgeneral autobiographical memory (OGM) is prevalent among patients with clinical depression. However, the prediction of OGM in groups with non-clinical depression and its influencing mechanisms remain inconclusive. Studies have shown that OGM and early parenting behaviour are vulnerable factors of depression in emerging adulthood, which may be triggered by negative life events. Our longitudinal study included 241 participants (M_age = 21.88 years). At baseline, participants completed measures of current negative life events, depression, early parenting behaviour and an autobiographical memory test. Thereafter, they were tracked for depression every 35 days. We used the latent class growth model to differentiate levels and trends of depression among non-clinical participants. The analysis showed that the effect of negative life events on depression was moderated by OGM and early parenting behaviour. However, this moderating effect was found only in the low-risk depression group. Our findings indicate that early parenting behaviour might account for the different mechanisms of OGM production in non-clinical groups. Moreover, it underlines the importance of OGM and early parenting behaviour as potential predictors of future depression in non-clinical groups.

Most people experience positive involuntary mental imagery (IMI) frequently in daily life; however, evidence for the importance and effects of positive IMI is largely indirect. The current study adapted a paradigm to experimentally induce positive IMI in participants' daily lives. This could in turn provide a means to directly test positive IMI's effects. In a within-subjects design, participants (N = 41) generated positive mental images (imagery condition) and sentences (verbal condition) from photo cues, half of which participants provided from their own living environment. Participants then recorded involuntary memories of the previously generated images or sentences in a seven-day diary, before returning to the lab and completing some measures including an involuntary memory task. In the diary, participants reported more involuntary memories from the imagery condition than from the verbal condition, and more involuntary memories from their own photos compared to the other photos. A more mixed pattern of findings was found across other tasks in the lab. The study indicates that the paradigm can be used as a means to induce positive IMI and that using photos as the basis for generating positive imagery increases the amount of IMI in daily life. Theoretical and potential clinical implications are discussed.

We compared the benefit of production and drawing on recall of concrete and abstract words, using mixed- and pure-list designs. We varied stimulus and list types to examine whether the memory benefit from these strategies was sustained across these manipulations. For all experiments, the memory retrieval task was free recall. In Experiment 1, participants studied concrete and abstract words sequentially, with prompts to either silently-read, read aloud, write, or draw each target (intermixed). Reading aloud, writing, and drawing improved recall compared to silent reading, with drawing leading to the largest boost. Performance, however, was at floor in all but the drawing condition. In Experiment 2, the number of targets was reduced, and each strategy (between-subjects) was compared to silent-reading. We eliminated floor effects and replicated results from Experiment 1. In Experiment 3, we manipulated strategy in a pure-list-design. The drawing benefit was maintained while that from production was eliminated. In all experiments, recall was higher for concrete than abstract words that were drawn; no such effect was found for words produced. Results suggest that drawing facilitates memory by enhancing semantic elaboration, whereas the production benefit is largely perceptually based. Importantly, the memory benefit conferred by drawing at encoding, unlike production, cannot be explained by a distinctiveness account as it was relatively unaffected by study design.

The study aimed to analyse the relationship between the dimensions of the triarchic model of psychopathy (meanness, boldness and disinhibition) and the phenomenological characteristics of Autobiographical Memory (AM) in a sample of university students, examining potential gender differences. Participants (N = 260; 55.4% women; aged 18-25) performed an AM task, followed by the Autobiographical Memory Characteristics Questionnaire and the Triarchic Psychopathy Measure. We found gender differences, with men scoring higher than women in meanness and disinhibition as well as in precision, accessibility, sharing and narrative coherence of AM. Correlations showed that boldness was negatively related to the valence and emotional intensity of the memory. Meanness was positively associated with precision, sensory details, accessibility, sharing, narrative coherence, distancing and preoccupation with emotions and negatively with recollection. Disinhibition was positively related to precision, sensory details and accessibility and negatively to intensity, distancing and preoccupation with emotions. Our results suggest that psychopathic traits could predict certain characteristics of AM, highlighting the predictive value of meanness, especially regarding memory quality characteristics (e.g., precision), as well as disinhibition, concerning the emotional content (e.g., preoccupation with emotions). Our results contribute to understanding psychopathy through an autobiographical perspective, showing how psychopathic traits may shape how people remember personal events.

It has been documented that older adults' memory deficits can be reduced for information depicted as personally and socially important (e.g., Hargis & Castel, 2017 [Younger and older adults' associative memory for social information: The role of information importance. Psychology and Aging, 32(4), 325-330]). The current study aimed to further assess the effects of both arbitrarily assigned and self-perceived importance in younger and older adults' memory for names (low in schematic support) and occupations (high in schematic support) associated with faces. Participants studied the same 16 face-name-occupation triplets (with neutral facial expressions) across four blocks, each including a free recall of names and occupations. At the end, they completed a cued recall of names and occupations. The faces were arbitrarily cued as socially important (i.e., with an orange frame) or unimportant (e.g., without a frame). The perceived social importance was assessed by rating all the triplets based on a 10-point Likert Scale (1 = least and 10 = most important) at the end. The results showed that age-related memory deficits were reduced or even eliminated for occupations (high in schematic support) relative to names (low in schematic support), especially in the free recall of faces self-perceived as important. In other words, the combination of schematic support and self-perceived importance can effectively mitigate older adults' memory deficit.

According to recent theoretical work, certain event memories are more likely to be remembered or forgotten in their entirety. This prior work focused on collections of concepts, such as person-location-object triples. To explore this idea with complex materials, we created triples of people, locations, objects, or activities from events in real-world novels. People who had read one of the included novels were provided with one element from these triples (the cue) and asked to identify which of six alternatives best went with it. The results revealed that memory for the narrative events remained stable across many years. Moreover, people recalled events in a more holistic manner than would be expected by chance. This was more likely the more causally important an event was. This pattern of performance also remained stable over time. Our results are consistent with the idea that event models involve integrating separate elements into a single coherent representation, and this is likely to stay integrated over long periods of time. However, the degree to which this is so appears to be related to how well-integrated the information is within a larger set of events.

Learners can study foreign language-English vocabulary (e.g., denken - to think) both receptively and productively. Receptive learning involves being cued with a foreign language word (e.g., denken) and trying to translate it (i.e., to think). Productive learning involves being cued with an English word (e.g., to think) and trying to produce the translation. When students use retrieval practice to learn foreign-language translations in one direction (e.g., receptively) until they correctly recall the translation, do they demonstrate transfer in the other direction (i.e., productively)? Across three experiments, we answered this question by manipulating the order of learning schedule (reception first followed by production or vice versa). For a given schedule, participants continued to practice retrieving translations (with feedback) using the dropout method until they correctly recalled each translation three times; they then proceeded to practice the pairs in the opposite direction until they correctly recalled each translation three times. Across all experiments, transfer was partial (learning in one direction did not entirely eliminate the need to practice in the other), but transfer did occur regardless of which schedule students used first during practice.

A small wearable camera, SenseCam, passively captured pictures from everyday experience that were later used to evaluate the accuracy and completeness of autobiographical memory. Nine undergraduates wore SenseCams that took pictures every 10 s for two days. After one week and one month, participants first recalled their experiences from specific time periods (timeslices), then reviewed the corresponding pictures to make corrections and report information omitted from initial recall. Results demonstrated the utility of wearable cameras as research tools, and illustrated several characteristics of everyday memory. Recall contents reflected the structure of undergraduate lives. Three different types of omissions were reported: neglected, reminded, and forgotten. Pictures stimulated memory, even for non-visual information (e.g., feelings, thoughts), increasing recall by 23%. The mean completeness of initial recall was 79% (upper bound), with at least 21% forgetting. Accuracy was self-scored by participants (M = 89%), and the mean error rate (11%) provided evidence against strong reconstructive and copy theories of memory. The characteristics of errors shed light on the cognitive processes underlying them. Ratings of recall (confidence, reliving, knowledge, and frequency) supported the episodic/semantic distinction, the dual-process theory of repetition, and reconstructive imagery. Metamemory measures showed a positive correlation between confidence and accuracy.
