Memory and Cognitive Science

Recent research suggests that human memories are stored not between neurons as synaptic weights, but within individual neurons themselves. This opens the possibility to replace the dominant paradigm of brain function – neural networks – with a new one. In this article, I explore how “identified neurons” could explain how memories are stored, and how human traits are implemented in the brain.

Traditionally, philosophers consider the question of whether episodic memory and imagination belong to the same kind (the (dis)continuism problem) as ultimately depending on the causality question - i.e., whether remembering requires a causal connection to the past event. In this framework, if memory is a simulation process (as claimed by simulationism) and does not require a causal connection, then it is sufficiently similar to imagination and, thus, continuism follows. On the other hand, if a causal connection is necessary for memory (...) (as defended by causalism), then there are fundamental differences between memory and imagination and, thus, discontinuism follows. In contrast with this framework, I will argue that such entanglement is due to a failure of clearly delineating issues of explanation and classification. By distinguishing these matters more explicitly, I conclude that continuism is the better alternative for classification purposes, while maintaining that causalism is still necessary for explaining how memory works.

Plaçant au centre de ses recherches la vie affective humaine, Théodule Ribot (1839-1916), qui participe au développement de la psychologie scientifique en France, est l’un des premiers à penser les rapports entre mémoire et émotions. Au sein de ce qu’il appelle la « mémoire affective », Ribot pense qu’il existe une mémoire spécifique des émotions. A l’intérieur de la communauté des psychologues scientifiques sa proposition a pour effet d’initier un débat à propos de l’existence, de la définition et du contenu (...) de cette mémoire. Le présent article vise à proposer une synthèse et une analyse critique du développement théorique de la notion de « mémoire affective » au début du 20 e siècle. Après avoir détaillé les propositions initiales de Ribot, nous mettons en évidence l’émergence progressive d’un consensus : même si d’un point de vue théorique il est possible de distinguer la mémoire affective de la mémoire intellectuelle, tout souvenir présente des éléments intellectuels et des éléments affectifs à des degrés variables, allant de l’évocation abstraite du passé grâce aux concepts langagiers, à la reviviscence de l’émotion passée. Si dans le cadre académique ces débats sont tombés dans l’oubli, nous montrons brièvement à la fin de cet article qu’il est toutefois possible d’établir une continuité conceptuelle avec la recherche actuelle en sciences cognitives et en neurosciences, qui gagneraient à relire cette littérature centenaire.

Belief storage is often modeled as having the structure of a single, unified web. This model of belief storage is attractive and widely assumed because it appears to provide an explanation of the flexibility of cognition and the complicated dynamics of belief revision. However, when one scrutinizes human cognition, one finds strong evidence against a unified web of belief and for a fragmented model of belief storage. Using the best available evidence from cognitive science, we develop this fragmented model into (...) a nascent theory of the cognitive architecture of belief storage. (shrink)

Theories of consciousness divide over whether perceptual consciousness is rich or sparse in specific representational content and whether it requires cognitive access. These two issues are often treated in tandem because of a shared assumption that the representational capacity of cognitive access is fairly limited. Recent research on working memory challenges this shared assumption. This paper argues that abandoning the assumption undermines post-cue-based “overflow” arguments, according to which perceptual conscious is rich and does not require cognitive access. Abandoning it also (...) dissociates the rich/sparse debate from the access question. The paper then explores attempts to reformulate overflow theses in ways that don’t require the assumption of limited capacity. Finally, it discusses the problem of relating seemingly non-probabilistic perceptual consciousness to the probabilistic representations posited by the models that challenge conceptions of cognitive access as capacity-limited.

Assuming that an agent can be morally responsible for her forgetting to do something, we can use recent psychological research on prospective memory to assess the psychological assumptions made by normative accounts of the moral responsibility for forgetting. Two accounts of moral responsibility have been prominent in recent debates about the degree to which agents are blameworthy for their unwitting omissions. This paper highlights the psychological assumptions concerning remembering and forgetting that characterise the accounts. The paper then introduces and reviews (...) recent empirical literature on prospective memory. Finally, it uses the literature to assess the various assumptions. One important implication is that a direct capacitarian control account implies implausible assumptions about the psychological capacity for remembering. A second important implication is that an indirect capacitarian control account and a valuative account highlight different but complementary aspects of remembering and forgetting. (shrink)

Fear generalisation is a psychological phenomenon that occurs when fear that is elicited in response to a frightening stimulus spreads to similar or related stimuli. The practical harms of pathological fear generalisation related to trauma are well-documented, but little or no attention has been given so far to its epistemic harms. This paper fills this gap in the literature. It shows how the psychological phenomenon, when it becomes pathological, substantially curbs the epistemic agency of those who experience the fear that (...) generalizes, limiting their ability to respond to evidence, and substantially limiting their epistemic horizons. It is argued that when these epistemic harms are caused by wrongful actions and decisions of individuals or institutions, because the fear is elicited in response to a traumatic experience inflicted by them, the harms should be considered epistemic wrongs. The epistemic wrongs are closely akin to agential epistemic injustice, a variety of distributive epistemic injustice, and sometimes also involve epistemic exclusion. The paper thereby identifies a previously underexplored psychological mechanism that can be a vehicle through which both individuals and institutions can epistemically wrong others. The argument has implications for how both epistemic wrongs and epistemic injustice should be conceived, suggesting that both can occur without being caused by primarily epistemic flaws or errors, or a bad epistemic character. Finally, it highlights the advantage of taking a victim-centred approach to understanding epistemic harm. (shrink)

Collective memory researchers predominantly in the cultural and social sciences have commonly understood the concept of collective memory as a mere metaphor, as something not existing in itself as memory but useful only as a tool for referring to the way groups construct shared representations of their past. Few have however addressed the question of whether it is a metaphor or literal in its own right. This paper looks at the plausibility of the claim that collective memory is a mere (...) metaphor by probing its presuppositions, where the representationalist theory of mind emerges as the ground for such a claim. Then appealing to the externalist model of the mind championed in recent studies of mind in disciplines as varied as philosophy, cognitive science, evolutionary biology, and collective intentionality studies, we try to expose the presuppositions of that claim, opening up possibilities for conceiving collective memory as not merely metaphorical but literal and naturally existing as memory.

The (dis)continuism debate in the philosophy and cognitive science of memory concerns whether remembering is continuous with episodic future thought and episodic counterfactual thought in being a form of constructive imagining. I argue that settling that dispute will hinge on whether the memory traces (or “engrams”) that support remembering impose arational, perception-like constraints that are too strong for remembering to constitute a kind of constructive imagining. In exploring that question, I articulate two conceptions of memory traces—the replay theory and the (...) prop theory—that return conflicting answers to whether remembering is constructive imagining. The prop theory’s vision of traces is suggestive of continuism, while the replay theory’s is a natural fit for discontinuism. Which view of traces is in fact correct remains undetermined by current empirical work. Nevertheless, it may already be possible to reach a compromise in the (dis)continuism debate, through the development of a conciliatory continuist causal theory. This view—only outlined here—accepts the continuism-friendly prop theory of traces, while still requiring that genuine remembering fulfills an appropriate causation condition, as required by the kinds of causal theories of remembering typically favored by discontinuists.

According to a standard view in psychology and neuroscience, there are multiple memory systems in the brain. Philosophers and scientists of memory rely on the idea that there are multiple memory systems in the brain to infer that procedural memory is not a cognitive form of memory. As a result, memory is considered to be a disunified capacity. In this paper, I evaluate two criteria used by Michaelian to demarcate between cognitive and non-cognitive memory systems: appeal to stored content and (...) retrieval flexibility. By considering several empirical cases I argue that the criteria offered ultimately fail to distinguish between memory systems. The procedural memory the system is neither contentless nor inflexible.

I suggest that the theories of remembering one finds in the philosophy of memory literature are best characterised as theories principally operating at three different levels of inquiry. Simulationist views are theories of the psychofunctional process type remembering. Causalist views are theories of referential remembering. Epistemic views are theories of successful remembering. Insofar as there is conflict between these theories, it is a conflict of integration rather than—as widely presented—head-on disagreement. Viewed in this way, we can see the previous awareness (...) condition and preservationism as principles applying at only some of the corresponding levels of inquiry. Where either principle has been rejected, it is, I claim, due to arguments which slip between these different levels. While the view of the landscape I offer does not dissolve ongoing disputes about the nature of remembering, it clarifies the dialectical rules of engagement, helping to clear the path for future, collaborative progress to be made. The view enables us to see less conflict in the recent philosophy of memory literature than there seems at face value to be. (shrink)

This paper aims to provide a psychologically-informed philosophical account of the phenomenology of episodic remembering. The literature on epistemic or metacognitive feelings has grown considerably in recent years, and there are persuasive reasons, both conceptual and empirical, in favour of the view that the phenomenology of remembering—autonoetic consciousness, as Tulving influentially referred to it, or the feeling of pastness, as we will refer to it here—is an epistemic feeling, but few philosophical treatments of this phenomenology as an epistemic feeling have (...) so far been proposed. Building on insights from the psychological literature, we argue that a form of feeling-based metacognition is involved in episodic remembering and develop an integrated metacognitive feeling-based view that addresses several key aspects of the feeling of pastness, namely, its status as a feeling, its content, and its relationship to the first-order memories the phenomenology of which it provides.

This paper engages the question of the extended mind hypothesis, specifically in terms of memory and mnemonics. I use the case of an external object which is set to trigger a memory internally, but is not the memory, to explore the idea of extension versus distribution. I use the example of tzitzit, which is a garment worn by observant Jewish men, where is states in scripture that seeing the tassels attached to the garment are supposed to trigger a specific memory. (...) The point of the essay is that extension is merely a metaphysical commitment, and that this commitment leads to some ethical issues. (shrink)

This paper purports to disprove an orthodox view in contemporary epistemology that I call ‘the epistemic conception of memory’, which sees remembering as a kind of epistemic success, in particular, a kind of knowing. This conception is embodied in a cluster of platitudes in epistemology, including ‘remembering entails knowing’, ‘remembering is a way of knowing’, and ‘remembering is sufficiently analogous to knowing’. I will argue that this epistemic conception of memory, as a whole, should be rejected insofar as we take (...) into account some putative necessary conditions for knowledge. It will be illustrated that while many maintain that knowing must be (1) anti-luck and (2) an achievement, the two conditions do not apply to remembering. I will provide cases where the subject successfully remembers that p but lacks knowledge that p for failing to meet the two putative conditions for knowledge. Therefore, remembering is not a kind of knowing but a sui generis cognitive activity. (shrink)

Martin and Deutscher’s causal theory of remembering holds that a memory trace serves as a necessary causal link between any genuine episode of remembering and the event it enables one to recall. In recent years, the causal theory has come under fire from researchers across philosophy and cognitive science, who argue that results from the scientific study of memory are incompatible with the kinds of memory traces that Martin and Deutscher hold essential to remembering. Of special note, these critics observe, (...) is that a single memory trace can be shaped by multiple past experiences. This appears to prevent traces from underwriting Martin and Deutscher’s distinction between remembering an event and merely forming an accurate representation of it. This paper accepts such criticisms of the standard causal theory and, through considering the phenomenon forgetting through repetition, raises several others. A substantially revised causal theory is then developed, compatible with the thesis that individual memory traces are shaped by multiple past experiences. The key strategy is to conceive of episodic remembering not as the simple retrieval and projection of a static memory trace, but as a complex quasi-inferential process that makes use of multiple forms of information and cues—“prop-like” memory traces included—in generating the experience known as episodic remembering. When remembering is understood as a multi-componential process, there are a variety of ways in which a representation of the past may be appropriately causally dependent upon a prior experience of the event remembered.

Conscious recollection, of the kind characterised by sensory mental imagery, is often thought to involve ‘episodically’ recalling experienced events in one’s personal past. One might wonder whether this overlooks distinctive ways in which we sometimes recall ordinary, persisting objects. Of course, one can recall an object by remembering an event in which one encountered it. But are there acts of recall which are distinctively objectual in that they are not about objects in this mediated way (i.e., by way of being (...) about events in which they featured)? This question has broad implications, not least for understanding the nature and role of imagery in remembering, the requirements of memory-based singular thought about objects, and the sense in which remembering involves ‘mental time travel’ through which one ‘relives’ past events. In this paper, I argue that we sometimes do recall objects from our past without remembering events in which they featured. The positive view of such cases I go on to propose draws on a wide body of empirical work in its support and accommodates a more nuanced picture of the role of imagery in remembering. In a slogan: remembering might essentially involve a kind of ‘re-experiencing’, but it need not involve ‘reliving’. (shrink)

Memory perspectives on past events allegedly take one of two shapes. In field memories, we recall episodes from a first-person point of view, while in observer memories, we look at a past scene from a third-person perspective. But this mere visuospatial dichotomy faces several practical and conceptual challenges. First, this binary distinction is not exhaustive. Second, this characterization insufficiently accounts for the phenomenology of observer memories. Third, the focus on the visual aspect of memory perspective neglects emotional, agential, and self-related (...) social aspects. Fourth, the focus on the time of recall neglects the fact that visual, emotional, agential, and social aspects of perspective can also be dissociated in the original experience. In this chapter, we move away from the standard visual dichotomy. Instead, we propose that memory perspective is better understood along four lines: visual, agential, emotional, and social. Drawing on empirical research, we argue that these dimensions predict a disposition to recall a past event based on the present situation of the memorizer. This account supports seeing episodic memory as a natural kind, supported by scenario construction mechanisms and minimal memory traces. By remapping the classic distinction between field and observer perspectives along four dimensions, our proposal provides explanatory advantages and secures practical gains by enabling testable hypotheses.

(written in 2017) According to Dorothea Debus (2007), all emotional aspects related to an act of remembering are present and new emotional responses to the remembered past event. This is a common conception of the nature of the emotional aspect of personal memories, if not explicitly defended then at least implicitly accepted in the literature. In this article, I first criticize Debus’ arguments and demonstrate that she does not give us valid reasons to believe that all the emotional aspects related (...) to a memory are present and new emotional responses to that past event. I then criticize Debus’ thesis tout court for being a direct consequence of assuming a particular conceptualization of the nature of emotions: emotions as physiological changes. Finally, based on a different conceptualization of emotions that focuses on their relational nature, I propose an alternative framework for analyzing the different possible emotional aspects of our personal memories. This leads me to conclude, contrary to Debus, that some emotional aspects of our memories are not occurrent emotions but are better conceived as quasi-emotions. (shrink)

La metáfora de la memoria como “viaje mental en el tiempo” (“mental time travel” en inglés) ha tenido una gran influencia en la ciencia cognitiva de la memoria así como también en la filosofía de la memoria contemporánea. A pesar de su relevancia, no ha habido ninguna discusión teórica real ni sobre el significado de la metáfora en sí misma ni sobre su adecuación para dar cuenta de los recuerdos de experiencias pasadas. Este artículo trata de llenar este vacío al (...) examinar con más detalle la metáfora del “viaje mental en el tiempo”, centrándose más específicamente en los problemas que dicha noción presenta. Si la metáfora del “viaje mental en el tiempo” pretende referir no solo a una facultad o sistema cerebral sino también a una experiencia subjetiva particular, como así ha sido sugerido en la literatura, no es de por sí evidente que sea compatible con las nociones de (re)construcción y simulación con las que se la asocia frecuentemente, ni que describa de manera fehaciente la fenomenología de todo recuerdo del pasado personal. Si, por el contrario, sólo se refiere a una facultad o sistema cerebral y no pretende dar cuenta de la fenomenología del recuerdo, el uso de dicho término parece perder todo sentido para nombrar dicha facultad. A pesar de su relevancia, la metáfora del “viaje mental en el tiempo” no se ha impuesto como paradigma único: otras metáforas distintas continúan guiando actualmente programas más o menos fructíferos de investigación de la memoria. El artículo concluye que aunque dicha metáfora fue beneficiosa en su momento para la ciencia y la filosofía de la memoria, el examen minucioso de dicha noción sugiere que no constituye realmente una buena metáfora de la memoria sobre las experiencias pasadas, por lo que debería ser abandonada.

In this paper, I argue that causal theories of memory are typically committed to two independent, non-mutually entailing theses. The first thesis pertains to the necessity of appropriate causation in memory, specifying a condition token memories need to satisfy. The second pertains to the explanation of memory reliability in causal terms and it concerns memory as a type of mental state. Post-causal theories of memory can reject only the first (weak post-causalism) or both (strong post-causalism) theses. Upon this backdrop, I (...) examine Werning’s (2020) causalist argument from probabilistic correlation. I argue that it doesn’t establish the necessity of appropriate causation and thus it can only target strong post-causalist theories. I end up by presenting some general considerations, suggesting that memories may not always be causally linked to past experiences. (shrink)

Remembering and forgetting are the two poles of the memory system. Consequently, any approach to memory should be able to explain both remembering and forgetting in order to gain a comprehensive and insightful understanding of the memory system. Can an enactive approach to memory processes do so? In this article I propose a possible way to provide a positive answer to this question. In line with some current enactive approaches to memory, I suggest that forgetting –similarly to remembering– might be (...) constituted within an embodied and active process. Within this process, some simulation and re-enactment paths would acquire more relevance than others. This acquired relevance would make the activation of other paths of recall less likely, thus preventing the memory system from engaging in some episodic simulations. These changes in the likelihood of activation of some paths of recall –the forgotten ones– can be accounted for in an enactive fashion by studying both “internal” and “external” re-enactment and simulation paths. With regard to the latter, I propose to examine the process of forgetting by considering the engagement and affective relation of an embodied agent with her field of affordances. I suggest that, in the case of emotion-laden memories, the agent’s decoupling from some affordances of the environment might contribute to the process of forgetting, in that it would reduce the agent’s opportunities for situated episodic simulations.

Patient RB has a peculiar memory impairment wherein he experiences his memories in rich contextual detail, but claims to not own them. His memories do not feel as if they happened to him. In this paper, I provide an explanatory model of RB’s phenomenology, the self-attentional model. I draw upon recent work in neuroscience on self-attentional processing and global workspace models of conscious recollection to show that RB has a self-attentional deficit that inhibits self-bias processes in broadcasting the contents of (...) episodic memories to the global workspace. Typically, self-related contents enjoy a higher salience level than other-related contents. Elimination of bias toward self-related contents diminishes the salience of those contents to the level of other-related contents. Because the typical high salience of self-related content is necessary for the feeling of ownership, RB lacks the feeling of ownership. I also discuss potential applications of the self-attentional model to other psychopathological cases. (shrink)

The notion of an object file figures prominently in recent work in philosophy and cognitive science. Object files play a role in theories of singular reference, object individuation, perceptual memory, and the development of cognitive capacities. However, the philosophical literature lacks a detailed, empirically informed theory of object files. In this paper, we articulate and defend the multiple-slots view, which specifies both the format and architecture of object files. We argue that object files represent in a non-iconic, propositional format that (...) incorporates discrete symbols for separate features. Moreover, we argue that features of separate categories are stored in separate memory slots within an object file. We supplement this view with a computational framework that characterizes how information about objects is stored and retrieved. (shrink)

The discovery of the engram, the physical substrate of memory, is a central challenge for the sciences of memory. Following the application of optogenetics to the neurobiological study of memory, scientists and philosophers claim that the engram has been found. In this paper, I evaluate the implications of applying optogenetic tools to the localization of the engram. I argue that conceptions of engram localization need to be revised to be made consistent with optogenetic studies of the engram. I distinguish between (...) challenges to vehicle and content localization. First, I consider the silent engram hypothesis. According to this hypothesis, optogenetic studies indicate that synaptic efficacy, the traditional engram-bearing vehicle, is important merely for retrieval. I argue that this interpretation rests upon a misunderstanding of accessibility. Second, I argue that optogenetic-based strategies and findings conflict with preservationist and constructivist views on memory storage. There is an enduring trace, but stored content may change over time and experience, resulting in doubt about what constitutes a single engram. (shrink)

When we remember a scene, the scene’s boundaries are wider than the boundaries of the scene we saw. This phenomenon is called boundary extension. The most important philosophical question about boundary extension is whether it is a form of perceptual adjustment or adjustment during memory encoding. The aim of this paper is to propose a third explanatory scheme, according to which the extended boundary of the original scene is represented by means of mental imagery. And given the similarities between perception (...) and mental imagery, the memory system encodes both the part of the scene that is represented perceptually and the part of the scene that is represented by means of mental imagery.

Pre-theoretically, it seems obvious that there are deep and multifarious relations between memory and emotions. On the one hand, a large chunk of our affective lives concerns the good and bad events that happened to us and that we preserve in memory. This is one amongst the many ways in which memory is relevant to the nature and causation of emotions. What does recent research teach us about these relations? § 1 surveys some key issues in this regard. On the (...) other hand, which events we happen to preserve in memory very much depends on how we affectively reacted to them when they took place. Emotions are relevant to the nature and causation of memory in this and many other ways. Key issues regarding these relations are surveyed in § 2. (shrink)

It seems natural to think that emotional experiences associated with a memory of a past event are new and present emotional states triggered by the remembered event. This common conception has nonetheless been challenged at the beginning of the 20th century by intellectuals who considered that emotions can be encoded and retrieved, and that emotional aspects linked to memories of the personal past need not necessary to be new emotional responses caused by the act of recollection. They called this specific (...) kind of memories “affective memories” and defended their existence. My aim here is to expound the historical background of this debate as well as the characterization and development of the notion of affective memory since its first inception. I aim to show that although the debate was left unresolved and the term disappeared from academy around 1930, many of the characterizations of the nature of emotions and memory done by the advocates of affective memory have reappeared in the scientific agenda and been further developed during the last decades.

Despite the popularity that the embodied cognition thesis has gained in recent years, explicit memories of events personally experienced are still conceived as disembodied mental representations. It seems that we can consciously remember our personal past through sensory imagery, through concepts, propositions and language, but not through the body. In this article, I defend the idea that the body constitutes a genuine means of representing past personal experiences. For this purpose, I focus on the analysis of bodily movements associated with (...) the retrieval of a personal memory, which have certain features that make them different from procedural memories, pragmatic actions and common gestures, as well as other forms of embodied memories found in recent literature. I refer to these as “kinetic memories” and analyse their representative nature as well as their adaptive functions. Kinetic memories are bodily movements in which some event or action that took place in the past can be seen, because they are an externalisation of the subject’s inner intention of representing a past personal experience. Kinetic memories represent a past experience sometimes by imitation of a past movement, and other times through embodied symbols and metaphors. Furthermore, although sometimes they present direct pragmatic benefits, such as communicative benefits, they seem to enhance the whole reexperience of the past event and memory recall, which I argue is one important adaptive value.

La investigación reciente en psicología cognitiva sobre la memoria emocional ha estudiado las distintas formas en que las emociones afectan a la memoria, sin profundizar no obstante en la comprensión de la manera en que los aspectos emocionales, afectivos y mnemónicos se encuentran estrechamente entrelazados en el contenido mismo de un acto de reminiscencia. En este artículo propongo un marco conceptual de análisis que nos permite entender los recuerdos personales como recuerdos esencialmente afectivos, y que se articula en torno a (...) dos variables continuas e independientes: por un lado, la intencionalidad del recuerdo, es decir, el objeto hacia el cual el recuerdo está dirigido, que puede ser descriptiva o evaluativa; por el otro, la perspectiva afectiva del recuerdo, que puede fluctuar desde la perspectiva de primera persona hasta la perspectiva de tercera persona. Las dos dimensiones son analizadas en profundidad y las limitaciones de este marco y las futuras líneas de investigación son igualmente presentadas. (shrink)

Is there a difference between recollecting episodes from the past and recalling autobiographically? Both in the philosophical and psychological literature, it does not seem that there is a consensus on whether autobiographical memories should be considered as a metaphysically equivalent concept to episodic memories or a different category of memory entirely. In this article, I give reasons to believe that autobiographical memories do not relate to the recollection of past episodes since they do not have an associated subjective experience and (...) the consequential experience of mental time travel. Autobiographical memories, I argue, are presented as a narrative that is constructed propositionally, thus differing substantially from episodic memory in its subjective property, the reference to the self, and the content in which each one is grounded. To do so, first I use data from the psychological literature on amnesic patients as evidence for both the difference in phenomenology and content. And second, I use insights from recent philosophical literature on memory and the self, to defend that what is referred here as “autobiographical memory” is indeed a different kind of memory that differs substantially from episodic memory and slightly from semantic memory.

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

When you hallucinate an object, you are not in the normal sort of concurrent causal sensory interaction with that object. It's standardly further inferred that the hallucinated object does not actually exist. But the lack of normal concurrent causal sensory interaction does not imply that there does not exist an object that is hallucinated. It might be a past‐perceived object. In this paper, I argue that this claim holds for at least some interesting cases of hallucination. Hallucinations generated by misleading (...) cues (e.g. ‘seeing’ Kanizsa triangles), hallucinations of Charles Bonnet Syndrome patients, and dreams are experiences of past‐perceived objects.

Episodic memory (memories of the personal past) and prospecting the future (anticipating events) are often described as mental time travel (MTT). While most use this description metaphorically, we argue that episodic memory may allow for MTT in at least some robust sense. While episodic memory experiences may not allow us to literally travel through time, they do afford genuine awareness of past-perceived events. This is in contrast to an alternative view on which episodic memory experiences present past-perceived events as mere (...) intentional contents. Hence, episodic memory is a way of coming into experiential contact with, or being again aware of, what happened in the past. We argue that episodic memory experiences depend on a causal-informational link with the past events being remembered, and that, assuming direct realism about episodic memory experiences, this link suffices for genuine awareness. Since there is no such link in future prospection, a similar argument cannot be used to show that it also affords genuine awareness of future events. Constructivist views of memory might challenge the idea of memory as genuine awareness of remembered events. We explain how our view is consistent with both constructivist and anti-causalist conceptions of memory. There is still room for an interpretation of episodic memory as enabling genuine awareness of past events, even if it involves reconstruction. (shrink)

Episodic memory—memory for personally experienced past events—seems to afford a distinctive kind of cognitive contact with the past. This makes it natural to think that episodic memory is centrally involved in our understanding of what it is for something to be in the past, or to be located in time—that it is either necessary or sufficient for such understanding. If this were the case, it would suggest certain straightforward evidential connections between temporal cognition and episodic memory in nonhuman animals. In (...) this paper, I argue that matters are more complicated than this. Episodic memory is memory for events and not for the times they occupy. As such, it is dissociable from temporal understanding. This is not to say that episodic memory and temporal cognition are unrelated, but that the relationship between them cannot be straightforwardly captured by claims about necessity and sufficiency. This should inform our theoretical predictions about the manifestations of episodic memory in nonhuman behaviour. (shrink)

Episodic memory has a distinctive phenomenology: it involves “mentally reliving” a past event. It has been suggested that characterising episodic memory in terms of this phenomenology makes it impossible to test for in animals, because “purely phenomenological features” cannot be detected in animal behaviour. Against this, I argue that episodic memory's phenomenological features are impure, having both subjective and objective aspects, and so can be behaviourally detected. Insisting on a phenomenological characterisation of episodic memory consequently does nothing to damage the (...) prospects for detecting it in nonhuman animals. (shrink)

The causal and simulation theories are often presented as very distinct views about declarative memory, their major difference lying on the causal condition. The causal theory states that remembering involves an accurate representation causally connected to an earlier experience. In the simulation theory, remembering involves an accurate representation generated by a reliable memory process. I investigate how to construe detailed versions of these theories that correctly classify memory errors as misremembering or confabulation. Neither causalists nor simulationists have paid attention to (...) memory-conjunction errors, which is unfortunate because both theories have problems with these cases. The source of the difficulty is the background assumption that an act of remembering has one target. I fix these theories for those cases. The resulting versions are closely related when implemented using tools of information theory, differing only on how memory transmits information about the past. The implementation provides us with insights about the distinction between confabulatory and non-confabulatory memory, where memory-conjunction errors have a privileged position. (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.

O presente artigo busca situar o leitor em alguns dos debates atuais acerca da memória episódica no âmbito da filosofia da memória. A memória episódica consiste na capacidade de lembrar daquilo que o sujeito vivenciou ao longo de sua vida. Um dos maiores problemas em filosofia da memória é estabelecer o que é uma memória episódica, e distingui-la de outros estados mentais, como a imaginação. As principais teorias que visam resolver tal problema são a Teoria Causal da Memória e a (...) Teoria Simulacionista da Memória. Causalistas insistem que deve haver um vínculo causal entre uma experiência vivida pelo sujeito no passado e a memória dessa experiência. Simulacionistas, em contrapartida, sustentam que tal vínculo causal não é necessário, pois uma memória é o resultado de um processo de simulação que combina elementos de várias memórias para formar um cenário que representa a experiência passada. Outro debate em filosofia da memória trata dos objetos da memória episódica, nele busca-se descobrir com o quê entramos em contato quando lembramos de um evento passado. Nesse debate as posições filosóficas mais defendidas são o Realismo Indireto e o Realismo Direto; o primeiro afirma que entramos em contato com representações do evento passado, já o último sustenta que entramos em contato diretamente com o evento passado. Esse artigo apresenta também teorias da psicologia sobre consolidação de memórias episódicas e a teoria da Mental Time Travel, afim de embasar o leitor, respectivamente, acerca dos mecanismos formadores da memória e do debate sobre a função da memória episódica.

In the history of external information systems, the World Wide Web presents a significant change in terms of the accessibility and amount of available information. Constant access to various kinds of online information has consequences for the way we think, act and remember. Philosophers and cognitive scientists have recently started to examine the interactions between the human mind and the Web, mainly focussing on the way online information influences our biological memory systems. In this article, we use concepts from the (...) extended cognition and distributed cognition frameworks and from transactive memory theory to analyse the cognitive relations between humans and the Web. We first argue that while neither of these approaches neatly capture the nature of human-Web interactions, both offer useful concepts to describe aspects of such interactions. We then conceptualize relations between the Web and its users in terms of cognitive integration, arguing that most current Web applications are not deeply integrated and are better seen as a scaffold for memory and cognition. Some highly personalised applications accessed on wearable computing devices, however, may already have the capacity for deep integration. Finally, we draw out some of the epistemic implications of our cognitive analysis. (shrink)

The past is undeniably special for human beings. To a large extent, both individuals and collectives define themselves through history. Moreover, humans seem to have a special way of cognitively representing the past: episodic memory. As opposed to other ways of representing knowledge, remembering the past in episodic memory brings with it the ability to become a witness. Episodic memory allows us to determine what of our knowledge about the past comes from our own experience and thereby what parts of (...) the past we can give testimony about. In this article, we aim to give an account of the special status of the past by asking why humans have developed the ability to give testimony about it. We argue that the past is special for human beings because it is regularly, and often principally, the only thing that can determine present social realities such as commitments, entitlements, and obligations. Because the social effects of the past often do not leave physical traces behind, remembering the past and the ability to bear testimony it brings is necessary for coordinating social realities with other individuals.

This paper responds to Bernecker’s attack on Michaelian’s simulationist account of confabulation, as well as his defence of the causalist account of confabulation :432–447, 2016a) against Michaelian’s attack on it. The paper first argues that the simulationist account survives Bernecker’s attack, which takes the form of arguments from the possibility of unjustified memory and justified confabulation, unscathed. It then concedes that Bernecker’s defence of the causalist account against Michaelian’s attack, which takes the form of arguments from the possibility of veridical (...) confabulation and falsidical relearning, is partly successful. This concession points the way, however, to a revised simulationist account that highlights the role played by failures of metacognitive monitoring in confabulation and that provides a means of distinguishing between “epistemically innocent” and “epistemically culpable” memory errors. Finally, the paper responds to discussions by Robins and Bernecker of the role played by the concept of reliability in Michaelian’s approach, offering further considerations in support of simulationism.

One popular theory of moral responsibility locates responsible agency in exercises of control. These control-based theories often appeal to tracing to explain responsibility in cases where some agent is intuitively responsible for bringing about some outcome despite lacking direct control over that outcome’s obtaining. Some question whether control-based theories are committed to utilizing tracing to explain responsibility in certain cases. I argue that reflecting on certain kinds of negligence shows that tracing plays an ineliminable role in any adequate control-based theory (...) of responsibility. (shrink)

Ockham developed two theories to explain the intentionality of memory: one theory that takes previously perceived things to be the objects of memory, and another that takes one’s own earlier acts of perceiving to be the objects of memory. This paper examines both theories, paying particular attention to the reasons that motivated Ockham to give up the first theory in favor of the second. It argues that the second theory is to be understood as a theory of double intentionality. At (...) the core of this theory is the thesis that one directly remembers one’s own acts, and indirectly also the objects of these acts. The paper analyzes the cognitive mechanism that makes this double intentionality possible and examines the causal account that Ockham gave for explaining the emergence of acts of remembering. It emphasizes that he accepted nothing more than a causal chain of acts and habits, thereby offering an ontologically parsimonious theory of memory. (shrink)
