In our article (Zawadzki and Adamczyk 2021), we analyzed threats that novel memory modifying interventions may pose in the future. More specifically, we discussed how optogenetics’ potential for reversible erasure/deactivation of memory “may impact authenticity by producing changes at different levels of personality.” Our article has received many thoughtful open peer commentaries for which we would like to express our great appreciation. We have identified two main threads of objections. They are related to the potential applicability of optogenetics as a (...) therapeutic memory modification technology (MMT) in humans—applicability thread, and the normative value of authenticity, that is, the assumption that preserving authenticity is valuable (either in general or in the particular approach we adopted)—normative thread. Both of these threads concern fundamental issues: The former deals with the scientific credibility of the case vignette on which our discussion is based, and the latter deals with the normative weight of our considerations. We think that addressing both of them can be instructive in a broader context as they reflect a more general disagreement among neuroethicists about the very purpose and method of our discipline.

One of the major works of an important modem philosopher, Matter and Memory investigates the autonomous yet interconnected planes formed by matter and perception on the one hand and memory and time on the other. Henry Bergson (1859-1941) was awarded the Nobel Prize in 1927. His works include Time and Free Will, An Introduction to Metaphysics, Creative Evolution, and The Creative Mind.

Memory occupies a fundamental place in philosophy, playing a central role not only in the history of philosophy but also in philosophy of mind, epistemology, and ethics. Yet the philosophy of memory has only recently emerged as an area of study and research in its own right. -/- The Routledge Handbook of Philosophy of Memory is an outstanding reference source on the key topics, problems and debates in this exciting area, and is the first philosophical collection of its kind. The (...) forty-eight chapters are written by an international team of contributors, and divided into nine parts: -/- The nature of memory The metaphysics of memory Memory, mind and meaning Memory and the self Memory and time The social dimension of memory The epistemology of memory Memory and morality History of philosophy of memory. -/- Within these sections, central topics and problems are examined, including: truth, consciousness, imagination, emotion, self-knowledge, narrative, personal identity, time, collective and social memory, internalism and externalism, and the ethics of memory. The final part examines figures in the history of philosophy, including Aristotle, Augustine, Freud, Bergson, Wittgenstein and Heidegger, as well as perspectives on memory in Indian and Chinese philosophy. -/- Essential reading for students and researchers in philosophy, particularly philosophy of mind and psychology, the Handbook will also be of interest to those in related fields, such as psychology and anthropology.

In the philosophy of memory there is a tension between a preservationist and a constructivist view of memory reflected in the debate between causalism and simulationism. Causalism is not only committed to the claim that there must be an appropriate causal connection between the remembered event and the content represented at retrieval but also that such connection is possible because of a content-preserving memory trace. Simulationism, by contrast, rejects the need for an appropriate causal condition and, thereby, makes the appeal (...) to memory traces unnecessary. In this paper I argue that while the are strong conceptual arguments and empirical evidence to support a constructivist view of memory, the empirical evidence also suggest that the initial formulation of simulationism needs to be revised. In particular, I argue, first, that simulationism’s commitment to a single cognitive system for mental time travel is likely wrong, and second, that simulationism cannot get rid of memory traces altogether, as they are still explanatorily indispensable when it comes to explaining a large number of memory-related phenomena. At the end, I end up suggesting a way of thinking about memory traces that, I think, is compatible with simulationism and a constructivist view of memory. If the view I put forth is on the right track, then an updated version of simulationism can help to dispel the dichotomy between causalism and simulationism as a false one. (shrink)

When pandemics hit communities, women are bound to suffer as most of the responsibilities of ensuring food security lie on them. This article assesses the impact of the COVID-19 pandemic on the role that church-going women play in food provision. The qualitative study used interviews and focus group discussions to examine the toll of the pandemic-induced restrictions, especially with regard to their disruption of activities that ensure the provision of food for the family. They sought to identify how an environment (...) as restrictive as the one that was imposed during the COVID-19 pandemic affects those largely responsible for food provision in urban Marondera – the women, in this case. The focus was extended to factor in how disasters and pandemics affect women and detract from their normative food procurement and provision roles in marginal societies and how these effects can be mitigated to allow women to carry on with their roles even in restrictive environments. This research was motivated by the recent COVID-19-imposed regulations that restricted the movement of people, restrictions that have only recently been relaxed and (in some cases) removed. We also sought to establish how gender roles are played out, together with whether they are exacerbated by pandemics, and in what ways these pandemics result in higher workloads on women. By utilising the Africana womanist theory, the study analysed women roles in food provision and food security in their societies within the restrictive environments of the pandemics.Contribution: This study concluded that there are gender inequalities that are exacerbated by these pandemics that result in higher workloads for women. It foregrounded how existing gender inequalities were exacerbated by the pandemic, resulting in higher workloads on women. It therefore recommended that women should form empowerment groups to help focus attention on food provision to mitigate challenges women face in this role. Finally, we averred that there ought to be consultation and participation of women on issues to do with pandemics to allow for their full and productive participation in critical roles of providing food.

The Centered Mind offers a new view of the nature and causal determinants of both reflective thinking and, more generally, the stream of consciousness. Peter Carruthers argues that conscious thought is always sensory-based, relying on the resources of the working-memory system. This system enables sensory images to be sustained and manipulated through attentional signals directed at midlevel sensory areas of the brain. When abstract conceptual representations are bound into these images, we consciously experience ourselves as making judgments or arriving at (...) decisions. However, our amodal propositional attitudes are never actually among the contents of this stream of conscious reflection. Our beliefs, goals, and decisions are only ever active in the background of consciousness, working behind the scenes. They are never themselves conscious.Drawing on extensive knowledge of the scientific literature on working memory and related topics, Carruthers challenges the central assumptions of many philosophers. In addition to arguing that non-sensory propositional attitudes are never conscious, he also shows that they are never under direct intentional control. Written with his usual clarity and directness, The Centered Mind will be essential reading for all philosophers and cognitive scientists interested in the nature of human thought processes. (shrink)

During the first half of the twentieth century, many philosophers of memory opposed the postulation of memory traces based on the claim that a satisfactory account of remembering need not include references to causal processes involved in recollection. However, in 1966, an influential paper by Martin and Deutscher showed that causal claims are indeed necessary for a proper account of remembering. This, however, did not settle the issue, as in 1977 Malcolm argued that even if one were to buy Martin (...) and Deutscher’s argument for causal claims, we still don’t need to postulate the existence of memory traces. This paper reconstructs the dialectic between realists and anti-realists about memory traces, suggesting that ultimately realists’ arguments amount to inferences to the best explanation. I then argue that Malcolm’s anti-realist strategy consists in the suggestion that causal explanations that do not invoke memory traces are at least as good as those that do. But then, Malcolm, I argue that there are a large number of memory phenomena for which explanations that do not postulate the existence of memory traces are definitively worse than explanations that do postulate them. Next, I offer a causal model based on an interventionist framework to illustrate when memory traces can help to explain memory phenomena and proceed to substantiate the model with details coming from extant findings in the neuroscience of memory.

Memories are mental states with a number of interesting features. One of those features seems to be their having an intentional object. After all, we commonly say that memories are about things, and that a subject represents the world in a certain way by virtue of remembering something. It is unclear, however, what sorts of entities constitute the intentional objects of memory. In particular, it is not clear whether those are mind-independent entities in the world or whether they are mental (...) entities of some kind. The purpose of this chapter is to map the different positions on this issue, and to highlight the virtues and difficulties for each of the options. In Section 2, I will specify the question of what the intentional objects of memory are by clarifying the relevant notions of memory and intentional object. In Section 3, I will motivate the significance of identifying the intentional objects of memory by exploring the relations between, on the one hand, the intentionality of memory and, on the other hand, the phenomenology and the epistemology of memory. In Section 4, I will consider two natural candidates for being the intentional objects of memory, namely, worldly entities and mental entities, and I will raise some concerns for each of the two candidates. A promising alternative will emerge, in Section 5, as preserving the virtues of the two original candidates while avoiding their difficulties. The alternative will concern a certain combination of worldly and mental entities; a combination that involves both causal and truth-making relations. I will conclude by sketching how the alternative candidate can shed some light on the phenomenological and epistemological issues raised in the third section. (shrink)

The Neuroethics of Memory is a thematically integrated analysis and discussion of neuroethical questions about memory capacity and content, as well as interventions to alter it. These include: how does memory function enable agency, and how does memory dysfunction disable it? To what extent is identity based on our capacity to accurately recall the past? Could a person who becomes aware during surgery be harmed if they have no memory of the experience? How do we weigh the benefits and risks (...) of brain implants designed to enhance, weaken or erase memory? Can a person be responsible for an action if they do not recall it? Would a victim of an assault have an obligation to retain a memory of this act, or the right to erase it? This book uses a framework informed by neuroscience, psychology, and philosophy combined with actual and hypothetical cases to examine these and related questions. (shrink)

This paper surveys the impact on neuropsychology of Wittgenstein's elucidations of memory. Wittgenstein discredited the storage and imprint models of memory, dissolved the conceptual link between memory and mental images or representations and, upholding the context-sensitivity of memory, made room for a family resemblance concept of memory, where remembering can also amount to doing or saying something. While neuropsychology is still generally under the spell of archival and physiological notions of memory, Wittgenstein's reconceptions can be seen at work in its (...) leading-edge practitioners. However, neuroscientists, generally, are finding memory difficult to demarcate from other cognitive and noncognitive processes, and I suggest this is largely due to their considering automatic responses as part of memory, termed nondeclarative or implicit memory. Taking my lead from Wittgenstein's On Certainty, I argue that there is only remembering where there is also some kind of mnemonic effort or attention, and, therefore, that so-called implicit memory is not memory at all, but a basic, noncognitive certainty.

Working Memory plays a crucial role in many high-level cognitive processes . The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside (...) of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM. (shrink)

Memory modification technologies (MMTs)—interventions within the memory affecting its functions and contents in specific ways—raise great therapeutic hopes but also great fears. Ethicists have expressed concerns that developing and using MMTs may endanger the very fabric of who we are—our personal identity. This threat has been mainly considered in relation to two interrelated concerns: truthfulness and narrative self‐constitution. In this article, we propose that although this perspective brings up important matters concerning the potential aftermaths of MMT utilization, it fails to (...) tell the whole story. We suggest that capturing more tangible potential consequences of MMT use, namely, its psychological ramifications is crucial both in ethical considerations and in making decisions regarding the permissibility of such interventions. To this end, we first examine what current MMTs are capable of and what are the prospects of emerging MMTs. Subsequently, we outline the relationship between memory and personal identity; specifically, we indicate that concepts of self‐defining memories and narrative identity are crucial to considering how MMTs may influence one's psychological functioning. On this basis, we analyze potential consequences of narrative disruption that may be the result of the use of MMTs; more precisely, we consider its potential effects on mental health, well‐being, and personal agency, and outline the ethical dilemmas that decision‐makers face in this context. We conclude by considering the broader cultural context that may have influence on policymaking regarding permissibility of memory modification interventions. (shrink)

Many recent AI systems take inspiration from biological episodic memory. Here, we ask how these ‘episodic-inspired’ AI systems might inform our understanding of biological episodic memory. We discuss work showing that these systems implement some key features of episodic memory whilst differing in important respects, and appear to enjoy behavioural advantages in the domains of strategic decision-making, fast learning, navigation, exploration and acting over temporal distance. We propose that these systems could be used to evaluate competing theories of episodic memory’s (...) operations and function. However, further work is needed to validate them as models of episodic memory and isolate the contributions of their memory systems to their behaviour. More immediately, we propose that these systems have a role to play in directing episodic memory research by highlighting novel or neglected hypotheses as pursuit-worthy. In this vein, we propose that the evidence reviewed here highlights two pursuit-worthy hypotheses about episodic memory’s function: that it plays a role in planning that is independent of future-oriented simulation, and that it is adaptive in virtue of its contributions to fast learning in novel, sparse-reward environments.

This article provides a summary of current knowledge about memory illusions. The memory illusions described here focus on the recall of imagined events that have never actually occurred. The purpose is to review theoretical ideas and empirical evidence about the reality-monitoring processes involved in memory illusions. Reality monitoring means deciding whether the memory has been perceptually derived or been self-generated (thought or imagined). A few key findings from the literature have been reported in this paper and these focus on internal (...) source-monitoring judgments which distinguish perceptual events from imagined events. Finally, the experimental paradigms used to shed light on processes occurring in the failure of reality monitoring in healthy subjects may be extended to an examination of the causes and the prevention of hallucinations in patients.

Defining consciousness along the lines of Nagel, an organism has consciousness iff there is something it is like to be that organism, I relate three types of consciousness (phenomenal, access and reflexive) to the three types of short-term memory (sensory memories, short-term working memory and the central executive). The suggestion is that these short-term memory stores may be a key feature of consciousness.

The experience of a reward appears to enhance memory for recent prior events, adaptively making that information more available to guide future decision-making. Here, we tested whether reward enhances memory for associative item-location information and also whether the effect of reward spreads to other categorically-related but unrewarded items. Participants earned either points (Experiment 1) or money (Experiment 2) through a time-estimation reward task, during which stimuli-location pairings around a 2D-ring were shown followed by either high-value or low-value rewards. All stimuli (...) were then tested for location memory or recognition (yes/no), immediately and after a 24-hour delay. Across both experiments (combined analysis), there was a robust improvement in location memory following high-value rewards, even though evidence supporting this effect was reliable in Experiment 2 but not in Experiment 1. The memory-enhancing effect of reward was observed on both the immediate and delayed location-memory tests. Reward-enhanced memory for both directly rewarded stimuli and categorically related stimuli that were not directly rewarded. No reliable effect of reward value on yes/no recognition-memory performance was observed in either experiment. We hypothesise that reward enhances the consolidation of recent experience and conceptually related memories to make these more available for future decisions. (shrink)

The momentum of globalization and universalism, operating through the media, information technology and politics, has steadily diminished the importance of cultural diversity. It has even threatened to erase many of our cultural traditions, or extinguish our diverse experiences of the sacred. Yet the sacred which seems to be lost is often still encased in our cultural objects, stories and religious rituals. This paper will discuss how the memories of the sacred can be both preserved and reawakened. This paper will focus (...) on three scholars who develop alternative approaches to the universal. Franz Rosenzweig saw universal historical progress as oppressive. He believed that the practice of his Jewish religion offered a resistance and a possible correction to the general movement of history. Walter Benjamin saw the forgotten 'ruins' of history encase memories of the sacred and the silenced voices within history. For Benjamin, the role of interpretation is to awaken these hidden memories and voices which are encoded within our objects, images and commodities. This led him to a particular idea of a momentary messianic redemption in relation to greater flow of time. And finally, Jacob Taubes read St. Paul as offering a revolutionary model on how to live one's particular faith within a wider political order. In general, each writer developed an idea of redemption which involves a kind of remembrance of what has been obscured by the more general universal movement of history itself. This is especially relevant for the various religious and cultural communities within Cambodia. The paper will begin and end by discussing the origin story of Cambodia – the marriage between Preah Thong, the Indian prince, and Neag Neak, the Naga princess. I will additionally try to demonstrate that the story and its various reenactments is important because it represents a regenerative process rooted in the eclectic character of South East Asian culture in general. Various forms of memory within the syncretic or eclectic context of Southeast Asia can operate to preserve the sacred in an age of universalization and globalization. It also illustrates how the performance of memory can also offer an antidote to the "trauma" of Cambodia's past. (shrink)

Various kinds of observations show that the ability of human beings to both consciously relive past events – episodic memory – and conceive future events, entails an active process of construction. This construction process also underpins many other important aspects of conscious human life, such as perceptions, language and conscious thinking. This article provides an explanation of what makes the constructive process possible and how it works. The process mainly relies on attentional activity, which has a discrete and periodic nature, (...) and working memory, which allows for the combination of discrete attentional operations. An explanation is also provided of how past and future events are constructed. (shrink)

Categorization and memory for specific items are fundamental processes that allow us to apply knowledge to novel stimuli. This study directly compares categorization and memory using delay match to category (DMC) and delay match to sample (DMS) tasks. In DMC participants view and categorize a stimulus, maintain the category across a delay, and at the probe phase view another stimulus and indicate whether it is in the same category or not. In DMS, a standard item working memory task, participants encode (...) and maintain a specific individual item, and at probe decide if the stimulus is an exact match or not. Constrained Principal Components Analysis was used to identify and compare activity within neural networks associated with these tasks, and we relate these networks to those that have been identified with resting state-fMRI. We found that two frontoparietal networks of particular interest. The first network included regions associated with the dorsal attention network and frontoparietal salience network; this network showed patterns of activity consistent with a role in rapid orienting to and processing of complex stimuli. The second uniquely involved regions of the frontoparietal central executive network; this network responded more slowly following each stimulus and showed a pattern of activity consistent with a general role in role in decision-making across tasks. Additional components were identified that were associated with visual, somatomotor and default mode networks. (shrink)

Psychotropic and other drugs can alter brain mechanisms regulating the formation, storage, and retrieval of different types of memory. These include “off label” uses of existing drugs and new drugs designed specifically to target the neural bases of memory. This paper discusses the use of beta-adrenergic antagonists to prevent or erase non-conscious pathological emotional memories in the amygdala. It also discusses the use of novel psychopharmacological agents to enhance long term semantic and short term working memory by altering storage and (...) retrieval mechanisms in the hippocampus and prefrontal cortex. Although intervention in the brain to alter memory as therapy or enhancement holds considerable promise, the long term effects of experimental drugs on the brain and memory are not known. More studies are needed to adequately assess the potential benefits and risks of these interventions. (shrink)
