Abstract
Repeated experience of events promotes schema formation. Later activation of the schema facilitates recall of the general structure of the events, whereas attribution of details to instances requires systematic decision-making based on detail characteristics. For repeated events, source monitoring may be less effective due to the similarity and interference of details across instances and consequently result in source attribution errors. To date, researchers have examined aggregated misattributions across instances and have found that misattributions are more frequent in the middle than in the boundary instances. In this study, we investigated the trajectories of misattributions using data from six studies (N = 633), where participants recalled repeated interactive marketing-themed events (Study 1), mock-crime filmed events (Study 2), stories (Study 3), and categorized word lists (Studies 4-6). The patterns confirmed the expected primacy and recency effects, showing fewer misattributions from and to the boundary instances relative to the middle instances. In addition, the patterns indicated proximity effects: Confusions more frequently occurred across adjacent instances and gradually decreased for instances that were further apart from the source. Our findings suggest that detail characteristics that form the basis of source attribution decisions provide information about the relative position of instances in repeated events, where the boundary instances serve as anchors, and where confusion relatively easily occurs across neighbouring instances. In line with context-based models of memory, our findings indicate that a higher-level organization of repeated events that emerges at encoding guides retrieval and source monitoring decisions.

Abstract
Research to date has exclusively focused on the implantation of false memories for single events. The current experiment is the first proof of concept that false memories can be implanted for repeated autobiographical experiences using an adapted false memory implantation paradigm. We predicted that false memory implantation approaches for repeated events would generate fewer false memories compared to the classic implantation method for single events. We assigned students to one of three implantation conditions in our study: Standard, Repeated, and Gradual. Participants underwent three interview sessions with a 1-week interval between sessions. In the Standard condition, we exposed participants to a single-event implantation method in all three interviews. In the Repeated condition, participants underwent a repeated-event implantation method in the three interviews. The Gradual condition also consisted of a repeated-event implantation method, however, in the first interview alone, we suggested to participants that they had experienced the false narrative once. Surprisingly, within our sample, false memories rates in the Standard condition were not higher compared to the Repeated and Gradual conditions. Although sometimes debated, our results imply that false memories for repeated events can be implanted in lab conditions, likely with the same ease as false memories for single events.

Abstract
Aims The aim of this study was to investigate the pattern, causes, and predictors of all new hospitalizations in patients who underwent transcatheter aortic valve implantation (TAVI). Methods and results The nationwide Swedish TAVI registry was merged with other mandatory healthcare registries, which enabled the analysis of all TAVI procedures, new hospital admissions, and death between the years 2008 and 2017. A total of 2821 patients underwent TAVI with a mean of 2.5 hospitalizations during a mean follow-up of 2.2 years. Hospitalizations were associated with worse prognosis. Heart failure (HF) was the most common cause of hospitalization with 19% having at least one hospitalization due to HF causing, 16% of all-cause admissions, and 50% of cardiovascular admissions. Male gender, age >90 years, high Charlson Comorbidity Index, atrial fibrillation, present neurologic disease, severe renal impairment, peripheral vascular disease, New York Heart Association class IV, mild or moderate mean aortic valve gradients, and pulmonary hypertension were associated with an increased risk for all-cause hospitalizations or death. For cardiovascular hospitalization or death, the pattern was similar, with the addition of impaired systolic left ventricular function as a predictor. Conclusion Multiple hospitalizations after TAVI are common and are often caused by HF. Reducing the rate of HF hospitalizations is important to mitigate the burden on the healthcare system due to new hospitalizations after TAVI.

Abstract
Reports about repeated experiences tend to include more schematic information than information about specific instances. However, investigators in both forensic and intelligence settings typically seek specific over general information. We tested a multi-method interviewing format (MMIF) to facilitate recall and particularisation of repeated events through the use of the self-generated cues mnemonic, the timeline technique, and follow-up questions. Over separate sessions, 150 adult participants watched four scripted films depicting a series of meetings in which a terrorist group planned attacks and planted explosive devices. For half of our sample, the third witnessed event included two deviations (one new detail and one changed detail). A week later, participants provided their account using the MMIF, the timeline technique with self-generated cues, or a free recall format followed by open-ended questions. As expected, more information was reported overall in the MMIF condition compared to the other format conditions, for two types of details, correct details, and correct gist details. The reporting of internal intrusions was comparable across format conditions. Contrary to hypotheses, the presence of deviations did not benefit recall or source monitoring. Our findings have implications for information elicitation in applied settings and for future research on adults' retrieval of repeated events.

Abstract
The Autobiographical Interview (AI) separates internal (episodic) and external (non-episodic) details from transcribed protocols using an exhaustive and reliable scoring system. While the details comprising the internal composite are centered on elements of episodic memory, external details are more heterogeneous as they are meant to capture a variety of non-episodic utterances: general semantics, different types of personal semantics details, metacognitive statements, repetitions, and details about off topic events. Elevated external details are consistently observed in aging and in neurodegenerative diseases. In the present study, we augmented the AI scoring system to differentiate subtypes of external details to test whether the elevation of these details in aging and in frontotemporal lobar degeneration (including mixed frontotemporal/semantic dementia [FTD/SD] and progressive non-fluent aphasia [PNFA]) would be specific to general and personal semantics or would concern all subtypes. Specifically, we separated general semantic details from personal semantic details (including autobiographical facts, self-knowledge, and repeated events). With aging, external detail elevation was observed for general and personal semantic details but not for other types of external details. In frontotemporal lobar degeneration, patients with FTD/SD (but not PNFA) generated an excess of personal semantic details but not general semantic details. The increase in personal but not general semantic details in FTD/SD is consistent with prevalent impairment of general semantic memory in SD, and with the personalization of concepts in this condition. Under standard AI instructions, external details were intended to capture off-topic utterances and were not intended as a direct measure of semantic abilities. Future investigations concerned with semantic processing in aging and in dementia could modify standard instructions of the AI to directly probe semantic content.

Abstract
BACKGROUND In some clinical situations, patients experience repeated events of the same type. Among these, cancer recurrences can result in terminal events such as death. Therefore, here we dynamically predicted the risks of repeated and terminal events given longitudinal histories observed before prediction time using dynamic pseudo-observations (DPOs) in a landmarking model. METHODS The proposed DPOs were calculated using Aalen-Johansen estimator for the event processes described in the multi-state model. Furthermore, in the absence of a terminal event, a more convenient approach without matrix operation was described using the ordering of repeated events. Finally, generalized estimating equations were used to calculate probabilities of repeated and terminal events, which were treated as multinomial outcomes. RESULTS Simulation studies were conducted to assess bias and investigate the efficiency of the proposed DPOs in a finite sample. Little bias was detected in DPOs even under relatively heavy censoring, and the method was applied to data from patients with colorectal liver metastases. CONCLUSIONS The proposed method enabled intuitive interpretations of terminal event settings.

Abstract
BACKGROUND Nursing home (NH) residents are frequent users of emergency departments (ED) and while prior research suggests that repeat visits are common, there is little data describing this phenomenon. Our objectives were to describe repeat ED visits over one year, identify risk factors for repeat use, and characterize "frequent" ED visitors. METHODS Using provincial administrative data from Ontario, Canada, we identified all NH residents 65 years or older who visited an ED at least once between January 1 and March 31, 2010 and then followed them for one year to capture all additional ED visits. Frequent ED visitors were defined as those who had 3 or more repeat ED visits. We used logistic regression to estimate risk factors for any repeat ED visit and for being a frequent visitor and Andersen-Gill regression to estimate risk factors for the rate of repeat ED visits. RESULTS In a cohort of 25,653 residents (mean age 84.5 (SD = 7.5) years, 68.2% female), 48.8% had at least one repeat ED visit. Residents who experienced a repeat ED visit were generally similar to others but they tended to be slightly younger, have a higher proportion male, and a higher proportion with minimal cognitive or physical impairment. Risk factors for a repeat ED visit included: being male (adjusted odds ratio 1.27, (95% confidence interval 1.19-1.36)), diagnoses such as diabetes (AOR 1.28 (1.19-1.37)) and congestive heart failure (1.26 (1.16-1.37)), while severe cognitive impairment (AOR 0.92 (0.84-0.99)) and 5 or more chronic conditions (AOR 0.82 (0.71-0.95)) appeared protective. Eleven percent of residents were identified as frequent ED visitors, and they were more often younger then 75 years, male, and less likely to have Alzheimer's disease or other dementias than non-frequent visitors. CONCLUSIONS Repeat ED visits were common among NH residents but a relatively small group accounted for the largest number of visits. Although there were few clear defining characteristics, our findings suggest that medically complex residents and younger residents without cognitive impairments are at risk for such outcomes.

Abstract
Ninety-five dental care patients participated in a quasi-experiment in which they were interviewed twice about dental visits they had made during the past ten years. Objective truth was established by analysing their dental records. The main purpose of the study was to investigate to what extent context-specific cues could facilitate particularization (i.e., recollection of events and details) of repeated and similar events. A mixed design was employed and the effects of three types of cues were explored: two types of context-specific cues vs. cues commonly used in police practise when interviewing plaintiffs. In line with our hypothesis, context-specific cues tended to be more effective for recollection of individual events than the comparison cues. In addition, context-specific cues generated more details than the comparison cues and the difference was marginally significant. Rehearsal of the memories by telling them to others was associated with an increased number of recollected events and details. The results are discussed from a legal psychology perspective with focus on recollection of repeated abuse.

Abstract
In this illustrative case study we examine the three forensic interviews of a girl who experienced repeated sexual abuse from ages 7 to 11. She disclosed the abuse after watching a serialized television show that contained a storyline similar to her own experience. This triggered an investigation that ended in successful prosecution of the offender. Because this case involved abuse that was repeated on a weekly basis for 4 years we thus investigated the degree to which the child's narrative reflected specific episodes or generic accounts, and both the interviewer's and child's attempts to elicit and provide, respectively, specific details across the 3 interviews collected in a 1 month period. Across the 3 interviews, the child's account was largely generic, yet on a number of occasions she provided details specific to individual incidents (episodic leads) that could have been probed further. As predicted: earlier interviews were characterized more by episodic than generic prompts and the reverse was true for the third interview; the child often responded using the same style of language (episodic or generic) as the interviewer; and open questions yielded narrative information. We discuss the importance of adopting children's words to specify occurrences, and the potential benefits of permitting generic recall in investigative interviews on children's ability to provide episodic leads. Despite the fact that the testimony was characterized by generic information about what usually happened, rather than specific episodic details about individual occurrences, this case resulted in successful prosecution.
