Behavioral and electrophysiological evidence for preserved specific associative episodic memory in older adults

Aging is often linked to a decline in associative memory. Prior research has shown that older adults have difficulty retrieving specific associative memory but can retrieve gist associative memory when deliberately differentiating test pairs with different levels of specificity during associative recognition. In this study, we utilized the context reinstatement paradigm to examine whether older adults could retrieve specific memory in situations where associations do not necessarily need to be voluntarily retrieved. Thirty-five older adults were directed to intentionally link objects with unique background scenes during encoding. Subsequently, test objects were presented against either the reinstated or similar background scenes during a recognition memory task, where participants were required to identify whether the objects were old or new regardless of their background contexts. Event-related potentials (ERP) were recorded to uncover the electrophysiological correlates of specific associative episodic memory. Behavioral results revealed higher memory sensitivity for object recognition when the background scenes were reinstated than when those were similar in older adults. ERP results indicated that older adults exhibited a more prominent fronto-centrally distributed positivity during object recognition in the reinstated than in similar contexts. Our results suggest that older adults may preserve their ability to retrieve specific memory for associations through an involuntary, spontaneous recollection process, which holds important theoretical implications for age-related associative memory deficits.

The Impact of Episodic Memory on Decision-Making in Aging: Scenarios from Everyday Life Situations.

Background: Decision-making is a highly complex process that depends on numerous cognitive functions, such as episodic memory. It is also influenced by aging. However, how changes in episodic memory with age contribute to changes in decision-making is not clear yet. Objective: This work aimed to examine the role of two memory processes, recollection and familiarity, in decision-making in ageing. Method: Thirty young adults and 30 older adults performed two episodic memory tasks: recognition, which allowed for the measurement of recollection and familiarity, and recall, which allowed for the measurement of recollection. In both tasks, they first viewed a series of pictures and then were asked to recognise or recall them respectively. They also performed an original scenario task based on situations inspired by everyday life, evaluating decision-making under conditions of either risk or ambiguity. In this task, participants were presented with short descriptions of situations requiring a decision and had to choose between two given options. Results: Lower performances was observed in recall and recognition tasks in older than in young adults. In the scenarios task, young adults sought significantly more risk and ambiguity than older adults. In both young and older adults, recollection and familiarity processes were involved differently in decision-making. The former is more involved in decision-making under ambiguity, and the latter in decision-making under risk. Conclusions: The results suggest that decision-making changes with age, but that the involvement of the episodic memory, familiarity and recollection processes, does not appear to vary with age.

“The Shifting Light of History”: Addressing Philosophy of Memory in Julian Barnes’s <i>Elizabeth Finch</i>

This article discusses the narrative construction of various philosophical reflections on cultural memory in Julian Barnes’s novel <i>Elisabeth Finch</i>. It addresses the dichotomy between recollection and oblivion, presenting a memory process as a the “problem of forgotten evidence”, thoroughly discussed in today’s Cultural and Memory Studies. While contemporary scholars and philosophers aim at reflecting on the role of memory in metaphysics and epistemology, mainly relating the process of recollection either to personal identity, or the experience of time, space and epistemic rationale, the dimension of collective memory, and its foregrounding role in everyone’s self-perceptiveness, receives a considerably reduced critical attention. The literary analysis of <i>Elizabeth Finch</i> seeks to problematize this divisive understanding of functions of memory, proposing instead to consider the semantic complementarity of various processes of recollection/forgetting, connecting the narrative representation of events that one has personally experienced and the officially stated collective renderings of factual memory. It resists considering personal remembering and collective forgetting as ostensibly competing rationales, proposing to delve deeper into a tightly crafted relationship between the perception of one’s identity in time and epistemological framework of collective experience mostly focused on the officially stated dimension of memory. Revisiting discourses on religion associated with the narrative construction of borderlands in Julian Barnes’s <i>Elizabeth Finch</i>, this article contributes to reconsider collective memory and counter-memory not as mutually exclusive, but as synthetized and put into productive motion narrative dimensions. The intertextual articulation of discourses on religion fosters new theoretical perspectives for rethinking counter-memory not only as a mode of recovering silenced and contested versions of the European history, but also as a means of providing multidimensional and transcultural interpretation of the collective past. Perceived as a form of discursive resistance to any kind of political and social dominance, the narrative construction of “forgotten evidence” elucidates the complex post-dialectical relationship between official collective memory and marginalized counter-memory.

The Dangers of (Masculine) Storytelling: Gender and Memory in Puig’s Sangre de amor correspondido

Drawing from the field of Cultural Memory Studies, this article examines the process of recollection as depicted in Sangre de amor correspondido (Seix Barral, 1982) by Manuel Puig (1932–1990). Within this novel, we witness the portrayal of memory processes through the eyes of Josemar, a marginalized construction worker from a small rural town in Brazil. The protagonist endeavors to narrate his life experiences through the lens of idealized hegemonic masculinity. Some scholars think that gender represents a fundamental facet of identity. Furthermore, identity emerges from introspective processes driven by memory. Consequently, this paper asserts that the integration and signifying of masculine prostheses hinge upon the articulation and solidification of a self-narrative rooted in “masculinity’s social frameworks of memory.” Through narration, hegemonic masculinity assumes a foundational role within individual identity; simultaneously, it disseminates the patterns—these social frameworks of memory—used for the interpretation and organization of life experiences as recollections.

Affective music during episodic memory recollection modulates subsequent false emotional memory traces: an fMRI study.

Music is a powerful medium that influences our emotions and memories. Neuroscience research has demonstrated music's ability to engage brain regions associated with emotion, reward, motivation, and autobiographical memory. While music's role in modulating emotions has been explored extensively, our study investigates whether music can alter the emotional content of memories. Building on the theory that memories can be updated upon retrieval, we tested whether introducing emotional music during memory recollection might introduce false emotional elements into the original memory trace. We developed a 3-day episodic memory task with separate encoding, recollection, and retrieval phases. Our primary hypothesis was that emotional music played during memory recollection would increase the likelihood of introducing novel emotional components into the original memory. Behavioral findings revealed two key outcomes: 1) participants exposed to music during memory recollection were more likely to incorporate novel emotional components congruent with the paired music valence, and 2) memories retrieved 1day later exhibited a stronger emotional tone than the original memory, congruent with the valence of the music paired during the previous day's recollection. Furthermore, fMRI results revealed altered neural engagement during story recollection with music, including the amygdala, anterior hippocampus, and inferior parietal lobule. Enhanced connectivity between the amygdala and other brain regions, including the frontal and visual cortex, was observed during recollection with music, potentially contributing to more emotionally charged story reconstructions. These findings illuminate the interplay between music, emotion, and memory, offering insights into the consequences of infusing emotional music into memory recollection processes.

Effects of congruent emotional contexts during encoding on recognition: An ERPs study.

Past research showed that emotional contexts can impair recognition memory for the target item. Given that item-context congruity may enhance recognition memory, the present study aims to examine the effect of the congruent emotional encoding contexts on recognition memory. Participants studied congruent word-picture pairs (e.g., the word "cow" - a picture describing a cow) and incongruent word-picture pairs (e.g., the word "cow" - a picture describing a goat) and, subsequently, were asked to report the nature of the picture (emotional or neutral). Behavioral results revealed that emotional contexts impaired source but not item recognition, with congruent word-context mitigating this impairment and enhancing item recognition. Neural results from ERPs and theta oscillations found the recollection process, as shown by the LPC old/new effect and theta oscillations, for both item and source recognition across emotional contexts, irrespective of congruity. Meanwhile, the familiarity process as indexed by the FN400 old/new effect was found only for item recognition in congruent emotional contexts. These findings suggest that the congruent relationship of item-context could mitigate the emotion-induced source memory impairment and enhance item memory, with neural results elucidating the memory processes involved in retrieval of emotional information. Specifically, while emotion-related information generally elicits the recollection-based memory process, only congruent emotional information elicits the familiarity-based process.

Judgments of Learning Reactivity on Item-Specific and Relational Processing.

Judgments of learning (JOLs) reactivity refers to the finding that the mere solicitation of JOLs modifies subsequent memory performance. One theoretical explanation is the item-specific processing hypothesis, which posits that item-level JOLs redound to the benefit of later memory performance because they enhance item-specific processing. The current study was designed to test this account. We factorially manipulated the organization (blocked vs. randomized) of categorized lists and JOL condition (item-JOLs, list-JOLs, no-JOLs) between participants, and fit the dual-retrieval model to free recall data to pinpoint the underlying memory processes that were affected by JOL solicitation. Our results showed that item-level JOLs produced positive reactivity for randomized but not for blocked categorized lists. Moreover, we found that the positive JOL reactivity for randomized categorized lists was tied to a familiarity judgment process that is associated with gist processing, rather than to item-specific recollective processes. Thus, our results pose a challenge to the item-specific processing explanation of JOL reactivity. We argue that JOL reactivity is not restricted to item-specific processing; instead, whether JOLs predominantly engage participants with item-specific or relational processing depends on the interaction between learning stimuli and JOLs.

Творче конструювання особистості в автобіографічній повісті (на матеріалі творів «Хризантеми» Уляни Кравченко та «Десь на дні мого серця» Василя Лопати)

The article analyzes the tools of creative personality construction in two autobiographical novels, Chrysanthemums by by Ulyana Kravchenko and Somewhere at the Bottom of My Heart by Vasyl Lopata, and the thematic and narrative features of these works, as well as the importance of including documentary elements in the plot, are clarified. It is determined that the tools that helped to depict the formation of the author's creative personality in an autobiographical story were a distanced view of oneself, both in appearance and in the inner world, the use of humor, and emphasis on important stages. There is a difference in the narrative style – Ulyana Kravchenko focuses on the goal of developing intellectually since childhood, evaluates herself according to her readiness to serve the people, to form herself according to artistic laws, so the plot is often interrupted by lyrical inserts and reflections, although she simultaneously supplements it with historical and portrait essays. He compensates for his silence and loneliness in childhood by realizing it in music and his first attempts at writing, and explains the lack of words already when writing his memoirs by his own emotionality, creating an aura of mystery and understatement. V. Lopata introduces the main narrator into the story for a different purpose: to provide textual explanations, comment on the narrator-child's story, and express a short future continuation of the described events, the author much less often focuses on the process of recollection itself, having clearly defined for himself its purpose: to find out the origins of his own creative formation, which has already taken place (Ulyana Kravchenko writes about it as a process). The fragment of the diary, introduced into the textual space of the work, demonstrates the naivety and vulnerability of the protagonist in the conditions of orphanhood and war, and shows the boy's tendency to perceive even everyday events deeply in order to later convey them in his work. Through the adult narrator, the childhood traumas are closed and «liberation» from the described situations of childhood powerlessness is projected into the future.

A handheld contactless conductivity detector for monitoring the desalting of low-volume virus and cell samples

Desalting of biosamples is crucial for analytical techniques intolerant to abundant salts. However, there is no simple tool to monitor the desalting of low-volume biosamples so far. Here we developed a handheld capacitively coupled contactless conductivity detector (hC4D) as a miniaturized device to measure the conductivity of 75 μL biosamples. Polyether-ether-ketone (PEEK) tubing was selected as the sample reservoir for sample loading via a pipette. Another pipetting of air pushed the sample solution out of the tubing to recollect the sample. Owing to the low sample consumption and easy sample recollection, hC4D is advantageous for testing expensive biosamples, such as viruses and cells. In addition, the whole process of sample injection, conductivity measurement, recollection, and calibration of conductivity can be completed within 1 min. To verify the feasibility of hC4D, we monitored the desalting progress of gel filtration (GF) of 200 μL blood samples, ultrafiltration (UF) of 300 μL virus samples, and dialysis of 7 mL cell samples. Three rounds of GF and UF completely removed the salts but led to poor sample recovery. In contrast, low concentrations of residual salts remained and better recovery was achieved after two rounds of GF and UF. We further utilized the hC4D to monitor the dialysis and tuned the salt concentration in the cell sample, such that we maintained the viability of cells in a low conductivity environment. These results indicated that hC4D is a promising tool for optimizing the desalting procedure of low-volume biosamples.

The use of distraction to improve episodic memory in ageing: A review of methods and theoretical implications.

Healthy ageing is characterized by changes in several cognitive functions, including episodic memory and inhibition. While the age-related decrease in the ability to inhibit irrelevant stimuli is often associated with lower performance, especially in episodic memory, some studies have highlighted the boosting effect of distraction in several tasks in older adults, including episodic memory tasks related to recollection. The aim of this article is to review and compare previous studies according to specific study features and to consider the results in light of the dual-process model of recollection and familiarity that were used by the authors of the reviewed articles. This work led to the identification of two major points of comparison between the studies: the timeline of the distraction intervention and the implicit nature of the processes at play, which both allowed for different implications to the relationship with recollection. The use of distraction in memory tasks can enhance episodic memory, and especially recollective processes, due to specific actions at encoding and retrieval. These findings open the door to further investigations but also raise several questions concerning the role of implicit processes and the negative impact of distraction, for example.

Myth, virtue and method in Plato’s Meno

This paper challenges the prevailing interpretations about the role and the function of recollection in Plato’s Meno, by suggesting that recollection is a cognitive process inaugurated by a myth. This process sets out the methodological and epistemological context within two transitions are feasible: On the one hand, the methodological transition from the elenchus to the method of hypothesis and, on the other hand, the cognitive upshift from opinions to knowledge. Furthermore, this paper argues that Socrates uses the myth of recollection just when Meno niggles and tries to escape the inquiry, introducing the paradox. Based on my deductions, Socrates’ myth imprints on Meno’s soul a true belief which facilitates the process of recollection by rending Meno valiant in continuing the inquiry.

Temporal Bell inequalities in cognition

There is widespread evidence that human memory is constructive, so that recollective processes may alter the information retrieved or impact on subsequent recollections. We examine a framework for narrowing down the nature of such processes, from physics. In Physics, the Temporal Bell (TB) inequality offers a general test of the sensitivity of the context of previous measurements in sequential measurement scenarios, as predicted by quantum theory. We present an empirical memory paradigm that allows a test of the TB inequality, using a novel kind of “change judgment,” whereby participants are asked to decide whether there has been a change in a question across different time points of a scenario. Across two experiments, we were able to observe evidence for the violation of a TB inequality in one case, offering evidence for quantum-like processes in memory. The present results complement other recent work purporting the relevance of quantum-like representations in memory and raise questions regarding the adaptive value of such representations.

Utilization of 5G Technologies in IoT Applications: Current Limitations by Interference and Network Optimization Difficulties-A Review.

5G (fifth-generation technology) technologies are becoming more mainstream thanks to great efforts from telecommunication companies, research facilities, and governments. This technology is often associated with the Internet of Things to improve the quality of life for citizens by automating and gathering data recollection processes. This paper presents the 5G and IoT technologies, explaining common architectures, typical IoT implementations, and recurring problems. This work also presents a detailed and explained overview of interference in general wireless applications, interference unique to 5G and IoT, and possible optimization techniques to overcome these challenges. This manuscript highlights the importance of addressing interference and optimizing network performance in 5G networks to ensure reliable and efficient connectivity for IoT devices, which is essential for adequately functioning business processes. This insight can be helpful for businesses that rely on these technologies to improve their productivity, reduce downtime, and enhance customer satisfaction. We also highlight the potential of the convergence of networks and services in increasing the availability and speed of access to the internet, enabling a range of new and innovative applications and services.

Benefits and Detriments of Social Collaborative Memory in Turn-Taking and Directed Forgetting.

Collaborative recall by groups of people can evoke both memory detriments (e.g., collaborative inhibition) and benefits (e.g., error pruning and post-collaborative memory benefit). Yet, it remains indeterminate whether these effects are due to the emotional valence of stimuli and/or the specific subtypes of episodic memory tested (i.e., item memory and source memory), and whether they are related to the research procedure of directed forgetting (DF). We introduced item-method DF into collaborative memory research using a turn-taking procedure. The to-be-recalled words were studied in different emotional valences and were followed by either an R or F cue, which, respectively, instructed participants to remember or forget the words presented. We conducted two recall sessions (Recall 1 and Recall 2) that included the two subtypes of episodic memory. Recall 1 was performed either individually or collaboratively, while Recall 2 was always performed individually. We observed three major findings: (a) a collaborative memory decrement - collaborative inhibition - was minimally affected in both item memory and source memory tasks by either the emotional valence of the stimuli or the DF cue; (b) a collaborative memory benefit - error pruning of item memory - persisted within both ongoing and post-collaboration, while error pruning of source memory only presented in ongoing collaboration, thus demonstrating the relevance of dual-process models that differentiate automatic familiarity and effortful recollection processes; and (c) there was no post-collaborative memory benefit, indicating the importance of the type of collaborative procedure. We discuss these results in terms of various theories, including the retrieval strategy disruption hypothesis (RSDH) which asserts that memory strategies tend to be disrupted in collaboration but are facilitated within post-collaboration. Also, we describe the implications of these results and directions for exploring other influential factors in future research.

Differentiation of the Contribution of Familiarity and Recollection to the Old/New Effects in Associative Recognition: Insight from Semantic Relation.

Previous research has revealed two different old/new effects, the early mid-frontal old/new effect (a.k.a., FN400) and the late parietal old/new effect (a.k.a., LPC), which relate to familiarity and recollection processes, respectively. Although associative recognition is thought to be more based on recollection, recent studies have confirmed that familiarity can make a great contribution when the items of a pair are unitized. However, it remains unclear whether the old/new effects are sensitive to the nature of different semantic relations. The current ERP (event-related potentials) study aimed to address this, where picture pairs of thematic, taxonomic, and unrelated relations served as stimuli and participants were required to discriminate the pair type: intact, rearranged, "old + new", or new. We confirmed both FN400 and LPC. Our findings, by comparing the occurrence and the amplitudes of these two components, implicate that the neural activity of associative recognition is sensitive to the semantic relation of stimuli and depends more on stimulus properties, that the familiarity of a single item can impact the neural activities in discriminating associative pairs, and that the interval length between encoding and test modulates the familiarity of unrelated pairs. In addition, the dissociation between FN400 and LPC reinforces the dual-process models.

Between Remembering and Forgetting in Adriana Altaras's Titos Brille (2011)

Abstract: This article considers how the demands of forgetting collide with the imperative for a coherent familial narrative in Adriana Altaras's memoir Titos Brille (2011; Tito's eyeglasses). Altaras's work engages with her family's post–World War II trauma between Croatia and Germany and points toward the parallel demands of national memory politics. The memoir grapples with the pressures of maintaining a story's continuity while reaching the limits of this project, as processes of recollection and omission are in constant tension. This article contextualizes Altaras's work within contemporary German memory politics and then considers Altaras's memoir in conversation with Astrid Erll's concept of traveling memory , Marianne Hirsch's work on postmemory, and the dybbuk figure of Jewish folklore. A feminist recognition of Altaras's distinctive role at the center of memory work, attentive to inequities based on gender and religious and national affiliation, deepens an understanding of the personal and political stakes of this mediation process.

A fi tigan sub Ceausescu

This article analyzes the Roma ethnic group image during the communist period, as it emerges from several stories narrated by Roma people living in two villages in Banat. Recollection process focuses both on the survival strategies of those years and on relationships with the majority. The latter acquired new dimensions, as the Gypsies began to engage in communist enterprises and part of them experienced an acculturation phenomenon.

Sense of agency may not improve recollection and familiarity in recognition memory

Sense of agency (SoA) is a feeling of controlling one’s own action. Recognition memory can improve for stimuli that involve SoA perhaps because of the self-reference effect. Recognition memory consists of recollection (i.e., detailed memory of stimuli) and familiarity (i.e., a feeling that stimuli are in memory). The self-reference effect is often observed in the recollection. Here, we investigated whether SoA particularly improves the recollection process. Participants pressed a key to produce an outcome (i.e., box movement followed by word presentation in Experiment 1 or word presentation in Experiment 2) and rated their SoA over the outcome. The outcome was spatially congruent or incongruent with the action. The participants learned the words intentionally (Experiment 1) or incidentally (Experiment 2). Performances of recollection and familiarity were assessed using the remember/know procedure. Our results suggest that the participants’ SoA was successfully manipulated. However, contrary to our hypothesis and previous findings, we found no effects of voluntary action and action–outcome congruence on recollection and familiarity processes of recognition memory, regardless of the latency of word presentation and learning strategies. Further studies are needed to replicate and elucidate the relationship between the SoA and recognition memory.

Fuzzy-trace theory and false memory: Meta-analysis of conjoint recognition.

The conjoint-recognition model (CRM) implements fuzzy-trace theory's opponent process conception of false memory. Within the family of measurement models that separate the memory effects of recollection and familiarity, CRM is the only one that accomplishes this for false as well as true memory. We assembled a corpus of 537 sets of conjoint-recognition data, with estimates of CRM's parameters plus goodness-of-fit statistics being available for all the data sets. This corpus was used to conduct a meta-analysis of CRM's underlying process assumptions by pitting two theoretical interpretations of the model against each other: (a) the original interpretation, which assumes that its retrieval parameters tap a single recollection process (verbatim retrieval) and a single familiarity process (gist retrieval), and (b) the dual-recollection interpretation, which assumes that its parameters also tap a second recollection process (context retrieval). The two interpretations generate a series of differential predictions that fall into three groups-namely, predictions about invariant relations among parameters, about the structure of CRM's parameter space, and about the location of individual parameters within the space. When these predictions were evaluated with the corpus, the results converged on the dual-recollection interpretation. The results also resolved a long-standing uncertainty about whether the familiarity process for true memory is semantically or perceptually driven.

Perceived gaze direction affects recollection processes in recognition of concrete and abstract words: electrophysiological evidence.

Studies have revealed that memory performance can be affected by perceived gaze direction. However, it remains unclear whether direct gaze promotes or hinders word memory, and the effect of gaze direction on memory of words with different concreteness requires investigation. In the study phase, concrete and abstract words were presented on direct- or averted-gaze faces, and participants were instructed to judge gaze direction and memorize words. In the test phase, participants were asked to discriminate whether a word was old or new. Electroencephalogram recordings were taken in both phases. Behavioral and time-frequency results verified the direct-gaze memory advantage, showing that memory performance was better in the direct-gaze condition than the averted-gaze condition for both concrete and abstract words. Event-related potential results showed that in both direct- and averted-gaze conditions, the early old/new effects (FN400) associated with familiarity were only elicited for concrete words but not abstract words. The late old/new effects (LPC) associated with recollection were elicited in all conditions. More importantly, concrete words elicited greater LPC than abstract words in the direct-gaze condition, whereas there was no such significant LPC difference in the averted-gaze condition. Topographic map analysis found that neural generators between concrete and abstract words differed in the direct-gaze condition but not in the averted-gaze condition. The study supports the hypothesis that direct-gaze promotes memory performance. Furthermore, it is mainly in memory recollection that gaze direction affects words with different concreteness.
