ABSTRACTIn my response to Ganeri's [2018] paper, I take Buddhagosha's deflationary account of episodic memory one step further through the analysis of the Madhyamaka philosopher Candrakīrti who, like Buddhagosha, explicitly defends episodic memory as a recollection of the objects experienced in the past, rather than subjective experience. However, unlike Buddhagosha, Candrakīrti deflates episodic memory by showing the incoherence of the Sautrāntika-Yogācāra's thesis that episodic memory requires the admission of reflexive awareness. Also unlike (...) Buddhagosha, Candrakīrti shows the incoherence of the Mimāṁsāka-Naiyāyika's self-implication requirement thesis, therefore directly countering Tulving's challenge to the Buddhist philosophers, by arguing that episodic memory is capable of mental time travel without any reference to the operation of enduring self. I will thus suggest that Candrakīrti may have even greater success in deflating the self-implication requirement of episodic memory. (shrink)

In Tulving’s initial characterization, episodic memory was one of multiple memory systems. It was postulated, in pursuit of explanatory depth, as displaying proprietary operations, representations, and substrates such as to explain a range of cognitive, behavioural, and experiential phenomena. Yet the subsequent development of this research program has, paradoxically, introduced surprising doubts about the nature, and indeed existence, of episodic memory. On dominant versions of the ‘common system’ view, on which a single simulation system underlies (...) both remembering and imagining, there are no processes unique to memory to support robust generalizations with inductive potential. Eliminativism about episodic memory seems to follow from the claim that it has no dedicated neurocognitive system of its own. After identifying this under-noticed threat, we push back against modern eliminativists by surveying recent evidence that still indicates specialized mechanisms, computations, and representations that are distinctly mnemic in character. We argue that contemporary realists about episodic memory can retain lessons of the common system approach while resisting the further move to eliminativism. (shrink)

Is an appropriate causal connection to the past experience it represents a necessary condition for a mental state to qualify as an episodic memory? For some years this issue has been the subject of an intense debate between the causalist theory of episodic memory (CTM) and the simulationist theory of episodic memory (STM). This paper aims at exploring the prospects for an embodied approach to episodic memory and assessing the potential case for (...) causalism that could be founded on it. In a critical section, it argues that the empirical data to which STM appeals are both incomplete and inconclusive, and on closer examination even provide support for a proceduralist version of CTM. In a constructive section, it elaborates on the notion of a necessary causal connection in terms of particular procedural patterns acquired at encoding and operative at retrieval, grounding this move on recent empirical data about eye movements in mnemonic mental imagery.

Episodic memory is sometimes described as mental time travel. This suggests three ideas: that episodic memory offers us access to the past that is quasi-experiential, that it is a source of knowledge of the past, and that it is, at root, passive. I offer an account of episodic memory that rejects all three ideas. The account claims that remembering is a matter of representing the past to oneself, in a way suitably responsive to how (...) one experienced the remembered episode to be. I argue that episodic memory is active, in the way this view suggests. I clarify the idea that it is, as the view also implies, not a source of knowledge but an expression of knowledge the subject already has. And I suggest the view need not limit memories to states that are in any way experience-like. This position offers a way to articulate the relations between episodic memory and related phenomena: factual memory, generic memory, remembering-how and anticipation. And it allows us to explain how we know which aspects of our episodic memory states to take seriously and which (such as the shift to an observer perspective on the remembered events) to treat as merely incidental. (shrink)

Episodic memory gives us the ability to mentally travel back in time to revisit and relive past experiences. In recent years, there has been an increased interest in the function of episodic memory. According to the orthodox view, episodic memory should be considered a part of a constructive system that simulates the future for sophisticated foresight and flexible planning. In this paper, I offer a novel alternative view. I argue that episodic memory (...) provides invaluable information about the past behavior of others, allowing us to identify reliable and trustworthy partners while avoiding dealing with cheaters. Theoretical models demonstrate that cooperation in groups can be maintained if potential partners use information about an individual’s past behavior to guide their behavior toward that individual. In these reputation-based models of human cooperation, individuals with a history of cheating are ostracized, whereas those with a history of cooperative behavior flourish. Against this theoretical background, it is possible to see a function of episodic memory in facilitating information exchange about others, helping group members make effective partner choices, and avoiding the risk of interacting with cheaters. If correct, episodic memory may have played a significant role in the evolution of human cooperation. (shrink)

According to recent social interactionist accounts in developmental psychology, a child's learning to talk about the past with others plays a key role in memory development. Most accounts of this kind are centered on the theoretical notion of autobiographical memory and assume that socio-communicative interaction with others is important, in particular, in explaining the emergence of memories that have a particular type of connection to the self. Most of these accounts also construe autobiographical memory as a species (...) of episodic memory, but its episodic character, as such, is not typically seen as falling within the remit of an explanation in social interactionist terms. I explore the idea that socio-communicative interaction centered on talk about the past might also have an important role to play, quite independently of considerations about the involvement of the self in memory, in accounting for the emergence of memories that are episodic in character, i.e., memories that involve the recollection of particular past events. In doing so, I also try to shed light on a distinctive role that talk about the past plays in socio-communicative interaction. (shrink)

In a recent paper, Cheng and Werning (2016) argue that the class of episodic memories constitutes a natural kind. Endorsing the homeostatic property cluster view of natural kinds, they suggest that episodic memories can be characterized by a cluster of properties unified by an underlying neural mechanism for coding sequences of events. Here, I argue that Cheng & Werning’s proposal faces some significant, and potentially insurmountable, difficulties. Two are described as most prominent. First, the proposal fails to satisfy (...) an important normative constraint on natural kind theorizing, not providing the requisite theoretical resources for arbitration between rival taxonomies of memory. Second, the proposal is in a direct tension with a foundational principle of the HPC view: the rejection of essentialism. This has far-reaching consequences, threatening to undermine the coherence of the proposal. (shrink)

This chapter examines the hypothesis that episodic memory is a mindshaped capacity. Presenting evidence from cognitive, developmental, and cross-cultural psychology, we argue that episodic memory is mindshaped for the purposes of interpersonal and social coordination. We examine how cultural influences, parental reminiscing styles, and the constructive nature of memory contribute to such mindshaping, promoting cognitive and behavioral homogeneity. We propose that epistemic norms of remembering are gradually acquired and internalized in practices of joint reminiscing between (...) children and adult caregivers, a crucial component in an extended process of normative enculturation. We also explore the close relationship between episodic memory and imagination, highlighting the ways in which simulated vicarious experiences function as socio-cognitive tools, transforming us into more easily interpretable cognitive objects. The chapter concludes by emphasizing the need for further research to elucidate the varieties and extent of memory mindshaping, shedding light on the nature of episodic memory and its role in the normative enculturation of human rememberers.

Ever since Tulving’s influential 1985 article “Memory and Consciousness” it has become traditional to think of autonoetic consciousness as necessary for episodic memory. This paper questions this claim. Specifically, it argues that the construct of autonoetic consciousness lacks validity and that, even if it was valid, it would still not be necessary for episodic memory. The paper ends with a proposal to go back to a functional/computational characterization of episodic memory in which its (...) characteristic phenomenology is a contingent feature of the retrieval process and, as a result, open to empirical scrutiny. The proposal also dovetails with recent taxonomies of memory that are independent of conscious awareness and suggests strategies to evaluate within- and between-individual variability in the conscious experience of episodic memories in human and non-human agents.

Direct realists about episodic memory claim that a rememberer has direct contact with a past event. But how is it possible to be acquainted with an event that ceased to exist? That’s the so-called cotemporality problem. The standard solution, proposed by Sven Bernecker, is to distinguish between the occurrence of an event and the existence of an event: an event ceases to occur without ceasing to exist. That’s the eternalist solution for the cotemporality problem. Nevertheless, some philosophers of (...) memory claim that the adoption of an eternalist metaphysics of time would be too high a metaphysical price to be paid to hold direct realist intuitions about memory. Although I agree with these critics, I will try to show two things. First, that this kind of “common sense argument” is far from decisive. Second, that Bernecker’s proposal remains the best solution to the cotemporality problem. (shrink)

Episodic memory (EM) involves re-experiencing past experiences by means of mental imagery. Aphantasics (who lack mental imagery) and people with severely deficient autobiographical memory (SDAM) lack the ability to re-experience, which would imply that they don't have EM. However, aphantasics and people with SDAM have personal and affective memories, which are other defining aspects of EM (in addition to re-experiencing). This suggests that these supposed aspects of EM really are independent faculties or modules of memory, and (...) that EM is a composite faculty rather than a natural kind. Apparent varieties of (normal and "defective") EM (as well as some closely related kinds of memory) are different combinations of these modules, and the EM construct itself adds little if any explanatory value to these modules.

It is widely held that episodic memory is constitutively connected with space and time. In particular, many contend that episodic memory constitutively has spatial and/or temporal content: for instance, necessarily representing a spatial scene, or when a given event occurred, or at the very minimum that it occurred in the past. Here, I critically assess such claims. I begin with some preparatory remarks on the nature of episodic memory. I then ask: How, if at (...) all, is episodic memory constitutively spatial? And, how, if at all, is episodic memory constitutively temporal? In answer, I argue that episodic memory need not have any spatial content, nor (in any substantial sense) need it represent when its events occur, nor even that they occur in the past. Instead, only a relatively modest connection holds between episodic memory and time in virtue of the temporal structure of its objects. Finally, I critically assess whether considerations concerning the organization and encoding of episodic memory in creatures like us provide stronger reason to posit a constitutive link between our episodic memories and space or time.

The question of what the function of human remembering might be has entered the contemporary philosophical discourse only relatively recently. In this debate, two main views have emerged: preservatism and simulationism. According to preservatism, the function of remembering is to preserve information from/about the past. In contrast, simulationism holds that the function of remembering is to enable reliable thought about the future. Here, I employ form to function reasoning to evaluate both of these views. I argue that both perservatism and (...) simulationism fail to account for the entire representational structure of episodic remembering. As an alternative, I then propose my own account: that the function of remembering is to track when we have epistemic authority about the past. (shrink)

This paper presents a challenge for exemplar theories of moral concepts. Some have proposed that we acquire moral concepts by way of exemplars of actions that are prohibited as well as of actions that are required, and we classify newly encountered actions based on their similarity to these exemplars. Judgments of permissibility then follow from these exemplar-based classifications. However, if this were true, then we would expect that individuals who lacked, or were deficient in, the capacity to form or access (...) exemplars of this kind would be similarly deficient in the ability to classify new actions according to them, and this relative inability would be manifested in the moral judgments made by such individuals. However, there is reason to suspect, I think, that a number of individuals who have been diagnosed with Autism Spectrum Disorder actually have the deficiencies I have described here but are nevertheless fully able to make sound moral judgments. If this is so, then it must be th... (shrink)

The relationship between perceptual experience and memory can seem to pose a chal- lenge for conceptualism, the thesis that perceptual experiences require the actualization of conceptual capacities. Since subjects can recall features of past experiences for which they lacked corresponding concepts at the time of the original experience, it would seem that a subject’s conceptual capacities do not impose a limit on what he or she can experience perceptually. But this conclusion ignores the fact that concepts can be composed (...) of other simpler concepts that a subject possessed earlier, and that de- monstrative capacities can explain how a subject can experience a particular feature of her environment, even when she lacks a fully general concept for that feature. Using these resources, conceptualism can explain the relation between perceptual experience and memory. Nevertheless, a puzzle remains for the defender of conceptualism. A cer- tain view about the relation between perceptual experience and mental imagery in epi- sodic memory – that imagery in recall matches the experience retained in it – can make it difficult to understand how conceptualism could be true. For if a subject’s conceptual capacities determine what the phenomenology of an experience (or memory of it) is like, then one would expect a perceptual experience and its recall in memory to differ in phenomenology if they involve different concepts. In this essay, I solve this puzzle for conceptualism by undermining the assumption that there is a match between im- agery in episodic memory and the phenomenal character of experience. (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.

We offer a framework for assessing what the structure of episodic memory might be, if one accepts the Buddhist denial of persisting selves. This paper is a response to Jonardon Ganeri's paper "Mental time travel and attention", which explores Buddhaghosa's ideas about memory. (It will eventually be published with a reply by Ganeri).

Mahr and Csibra view autonoesis as being essential to episodic memories and construction as being essential to the process of episodic remembering. These views imply that episodic memory is systematically misleading, not because it often misinforms us about the past, but rather because it often misinforms us about how it informs us about the past.

What kind of mental state is episodic memory? I defend the claim that it is, in key part, imagining the past, where the imagining in question is experiential imagining. To remember a past episode is to experientially imagine how things were, in a way controlled by one’s past experience of that episode. Call this the Inclusion View. I motive this view by appeal both to patterns of compatibilities and incompatibilities between various states, and to phenomenology. The bulk of (...) the paper defends the account against four objections. Imagining and remembering seem to differ in whether they are active or passive, in the forms of singular content they involve, in their relations to observation and in their relations to belief. I argue that these differences can be accommodated, and some even explained, once we flesh out what else is involved in episodic memory, in addition to imagining the past. (shrink)

According to simulationism, the function of episodic memory is not to remember the past, but to help construct representations of possible future episodes, by drawing together features from different experiential sources. This article suggests that the relationship between the traditional storehouse view, on which the function of memory is remembering, and the simulationist approach is more complicated than has been typically acknowledged. This is attributed, in part, to incorrect interpretations of what remembering on the storehouse view requires. (...) Further, by appeal to function pluralism, the article questions both the assumption that the traditional view and simulationism are inconsistent, and the simulationist’s inference to the best explanation strategy that is based upon this assumption. The article then provides an evaluation of the simulationist argument against the traditional view, and finds it in need of further support. (shrink)

Following the seminal work of Ingvar (1985. “Memory for the future”: An essay on the temporal organization of conscious awareness. Human Neurobiology, 4, 127–136), Suddendorf (1994. The discovery of the fourth dimension: Mental time travel and human evolution. Master’s thesis. University of Waikato, Hamilton, New Zealand), and Tulving (1985. Memory and consciousness. Canadian Psychology/Psychologie Canadienne, 26, 1–12), exploration of the ability to anticipate and prepare for future contingencies that cannot be known with certainty has grown into a thriving (...) research enterprise. A fundamental tenet of this line of inquiry is that future-oriented mental time travel, in most of its presentations, is underwritten by a property or an extension of episodic recollection. However, a careful conceptual analysis of exactly how episodic memory functions in this capacity has yet to be undertaken. In this paper I conduct such an analysis. Based on conceptual, phenomenological, and empirical considerations,I conclude that the autonoetic component of episodic memory, not episodic memory per se, is the causally determinative factor enabling an individual to project him or herself into a personal future. (shrink)

Compared to other forms of memory, episodic memory is commonly viewed as special for being distinctively metarepresentational and, relatedly, uniquely human. There is an inherent ambiguity in these conceptions, however, because “episodic memory” has two closely connected yet subtly distinct uses, one designating the recollective experience and the other designating the underlying neurocognitive system. Since experience and system sit at different levels of theorizing, their disentanglement is not only necessary but also fruitful for generating novel (...) theoretical hypotheses. To show this, I first argue that accepting the phenomenally conscious contents of episodic remembering as metarepresentational does not necessitate a metarepresentational conception of the episodic memory system. In its stead, I sketch an alternative account on which the metarepresentational character of episodic remembering is generated through the interaction of first-order outputs of the episodic memory system with other neurocognitive components of the brain. Complemented with a first-order account of the memory system, the system-experience distinction further supplies a novel understanding of the human uniqueness of episodic recollection, one that is compatible with there being an evolutionarily conserved episodic memory system. Overall, by distinguishing the two equivocal senses of “episodic memory” in our theorizing, we unearth an opportunity to understand how the distinctive phenomenology of our episodic recollection is related to and implemented in the cognitive architecture. (shrink)

In the recent literature on episodic memory, there has been increasing recognition of the need to provide an account of its adaptive function. In this context, it is sometimes argued that episodic memory is critical for certain forms of decision making about the future. We criticize existing accounts that try to give episodic memory a role in decision making, before giving a novel such account of our own. This turns on the thought of a (...) link between episodic memory and the emotion of regret. We discuss how both experienced and anticipated regret can have a distinctive influence on decision making, and argue that the ability to recollect past events in episodic memory underpins the capacity to engage in the sophisticated types of mental time travel recruited in experiencing and anticipating regret. (shrink)

The distinctive feature of episodic memory is autonoesis, the feeling that one’s awareness of particular past events is grounded in firsthand experience. Autonoesis guides us in sharing our experiences of past events, not by telling us when our credibility is at stake, but by telling us what others will find informative; it also supports the sense of an enduring self.

One of Clayton’s major contributions to our understanding of animal minds has been her work on episodic-like memory. A central reason for the success of this work was its focus on ecological validity: rather than looking for episodic memory for arbitrary stimuli in artificial contexts, focussing on contexts in which episodic memory would serve a biological function such as food caching. This review aims to deepen this insight by surveying the numerous functions that have (...) been proposed for episodic memory, articulating a philosophically grounded framework for understanding what exactly functions are, and drawing on these to make suggestions for future directions in the comparative cognitive psychology of episodic memory. Our review suggests four key insights. First, episodic memory may have more than one function and may have different functions in different species. Second, cross-disciplinary work is key to developing a functional account of episodic memory. Third, there is scope for further theoretical elaboration of proposals relating episodic memory to food caching and, in particular, future-oriented cognition. Finally, learning-related functions suggested by AI (artificial intelligence)-based models are a fruitful avenue for future behavioural research. (shrink)

Improved control of agency is likely to be a prior and more important function of episodic memory than the epistemic-communicative role pinpointed by Mahr and Csibra. Taking the memory trace upon which scenario construction is based to be a stored internal model produced in past perceptual processing promises to provide a better account of autonoetic character than metarepresentational embedding.

Episodic memory is memory for past events. It’s characteristically associated with an experience of ‘mentally replaying’ one’s experiences in the mind’s eye. This biological phenomenon has inspired the development of several ‘experience replay’ algorithms in AI. In this chapter, I ask whether experience replay algorithms might shed light on a puzzle about episodic memory’s function: what does episodic memory contribute to the cognitive systems in which it is found? I argue that experience replay (...) algorithms can serve as idealized models of episodic memory for the purposes of addressing this question. Taking the DQN algorithm as a case study, I suggest that these algorithms provide some support for mnemonic accounts, on which episodic memory’s function lies in the storage, encoding and retrieval of information. By extending and adapting experience replay algorithms, we might gain further insight into episodic memory’s operations and contributions to cognition. (shrink)

I will begin by proposing a taxonomy of taxonomic positions regarding the mind–brain: localism, globalism, revisionism, and contextualism, and will go on to focus on the last position. Although some versions of contextualism have been defended by various researchers, they largely limit themselves to a version of neural contextualism: different brain regions perform different functions in different neural contexts. I will defend what I call “environmental-etiological contextualism,” according to which the psychological functions carried out by various neural regions can only (...) be identified and individuated against an environmental context or with reference to a causal history. While this idea may seem innocuous enough, it has important implications for a structure-to-function mapping in the mind and brain sciences. It entails that the same neural structures can subserve different psychological functions in different contexts, leading to crosscutting psycho-neural mappings. I will try to illustrate how this can occur with reference to recent research on episodic memory. (shrink)

The purpose of this paper is not to show that the answer to the question in the title is ‘no’, but to show that it is ‘probably not’, at least on one particular theory of memory. Assuming that an experience will only be an episodic memory if we are ‘disposed to take the relevant experience into account when judging about the past’ (Debus 2010, p. 25), there are many obstacles to answering the question in the affirmative. If (...) one holds that it is possible to have episodic memories during dreams, they will have to accept more implications than may be palatable. Specifically, they will have to believe, contra Sosa (2007), that we can actually make judgments during dreams and not just imagine doing so; that we retain a fairly high degree of rationality during dreams; and that there is a respectable sense in which we can refer to the past at all when we dream.

Investigates the roles of temporal concepts and self-consciousness in the development of episodic memory. According to some theorists, types of long-term memory differ primarily in the degree to which they involve or are associated with self-consciousness (although there may be no substantial differences in the kind of event information that they deliver). However, a known difficulty with this view is that it is not obvious what motivates introducing self-consciousness as the decisive factor in distinguishing between types of (...) memory and what role it is supposed to play in remembering. The authors argue that distinctions between different kinds of memory should be made initially on the basis of the ways in which they represent events. In particular, it is proposed that the way in which remembered events are located in time provides an important criterion for distinguishing between different types of memory. According to this view, if there is a link between memory development and self-consciousness, it is because some temporal concepts emerge developmentally only once certain self-conscious abilities are in place.

In this paper I discuss philosophical and psychological treatments of the question "how do we decide that an occurrent mental state is a memory and not, say a thought or imagination?" This issue has proven notoriously difficult to resolve, with most proposed indices, criteria and heuristics failing to achieve consensus. Part of the difficulty, I argue, is that the indices and analytic solutions thus far offered seldom have been situated within a well-specified theory of memory function. As I (...) hope to show, when such an approach is adopted, not only does a new, functionally-grounded answer emerge; we also gain insight into the adaptive significance of the process proposed to underwrite our belief in the memorial status of a mental state (i.e.,autonoetic awareness). (shrink)

Episodic memory often is conceptualized as a uniquely human system of long-term memory that makes available knowledge accompanied by the temporal and spatial context in which that knowledge was acquired. Retrieval from episodic memory entails a form of first–person subjectivity called autonoetic consciousness that provides a sense that a recollection was something that took place in the experiencer’s personal past. In this paper I expand on this definition of episodic memory. Specifically, I suggest (...) that (a) the core features assumed unique to episodic memory are shared by semantic memory, (b) episodic memory cannot be fully understood unless one appreciates that episodic recollection requires the coordinated function of a number of distinct, yet interacting, “enabling” systems. Although these systems – ownership, self, subjective temporality, and agency – are not traditionally viewed as memorial in nature, each is necessary for episodic recollection and jointly they may be sufficient, and (c) the type of subjective awareness provided by episodic recollection (autonoetic) is relational rather than intrinsic – i.e., it can be lost in certain patient populations, thus rendering episodic memory content indistinguishable from the content of semantic long-term memory. (shrink)

The idea that episodic memory is distinguished from semantic memory by the fact that it involves autonoetic consciousness, initially introduced by Tulving, has been influential not only in psychology but also in philosophy, where a variety of approaches to autonoesis and to its relationship to episodicity have been developed. This article provides a critical review of the available philosophical approaches. Distinguishing among representational, metacognitive, and epistemic accounts of autonoesis, it considers these in relation to objective and subjective (...) conceptions of episodicity and assesses them against immediacy and source criteria that any philosophical account of autonoesis should arguably aim to satisfy.

Although the dream narrative, of (bio)logical necessity, originates with the dreamer, s/he typically does not know this. For the dreamer, the dream world is the real world. In this article I argue that this nightly misattribution is best explained in terms of the concept of mental ownership (e.g., Albahari, 2006; Klein, 2015a; Lane, 2012). Specifically, the exogenous nature of the dream narrative is the result of an individual assuming perspectival, but not personal, ownership of content s/he authored (i.e., “The content (...) in my head is not mine. Therefore it must be peripherally perceived”). Situating explanation within a theoretical space designed to address questions pertaining to the experienced origins of conscious content has a number of salutatory consequences. For example, it promotes predictive fecundity by bringing to light empirical generalizations whose presence otherwise might have gone unnoticed (e.g., the severely limited role of mental time travel within the dream narrative). -/- .

In this article, we explore various arguments against the traditional distinction between episodic and semantic memory based on the metaphysical phenomenon of transitional gradation. Transitional gradation occurs when two candidate kinds A and B grade into one another along a continuum according to their characteristic properties. We review two kinds of arguments—from the gradual semanticization of episodic memories as they are consolidated, and from the composition of episodic memories during storage and recall from semantic memories—that predict (...) the proliferation of such transitional forms. We further explain why the distinction cannot be saved from the challenges of transitional gradation by appealing to distinct underlying memory structures and applying our perspective to the impasse over research into ‘episodic-like’ memory in non-human animals. On the whole, we recommend replacing the distinction with a dynamic life cycle of memory in which a variety of transitional forms will proliferate, and illustrate the utility of this perspective by tying together recent trends in animal episodic memory research and recommending productive future directions.

Memory seems intuitively to consist in the preservation of some proposition (in the case of semantic memory) or sensory image (in the case of episodic memory). However, this intuition faces fatal difficulties. Semantic memory has to be updated to reflect the passage of time: it is not just preservation. And episodic memory can occur in a format (the observer perspective) in which the remembered image is different from the original sensory image. These difficulties (...) indicate that memory cannot be preserved content. It is proposed that what is preserved in memory isan underlying "trace", and that in every act of remembering, memorial content is reconstructed from the preserved trace. (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.

Many authors claim that being conscious constitutively involves being self-conscious, or conscious of oneself. This claim appears to be threatened by reports of `selfless' episodes, or conscious episodes lacking self-consciousness, recently described in a number of pathological and nonpathological conditions. However, the credibility of these reports has in turn been challenged on the following grounds: remembering and reporting a past conscious episode as an episode that one went through is only possible if one was conscious of oneself while undergoing it. (...) Call this the Memory Challenge. This paper argues that the Memory Challenge fails to undermine the credibility to reports of selfless episodes, because it rests on problematic assumptions about episodic memory. The paper further argues that we should distinguish between several kinds of self-representation that may be involved in the process of episodic remembering, and that once we do so, it is no longer mysterious how one could accurately remember and report a selfless episode as an episode that one went through. Thus, we should take reports of this kind seriously, and view them as credible counter-examples to the claim that consciousness constitutively involves self-consciousness. (shrink)

Are occurrent states of forgetting literal experiences of absences? I situate this question within the debate on mental time travel (MTT) to understand whether these states can be explained as literal experiences of absent episodic memories. To frame my argument, I combine Barkasi and Rosen’s literal approach to MTT with Farennikova’s literal approach to the perception of absences, showing that both are built on the idea that for an experience to be literal it must afford an unmediated contact with (...) the object that constitutes it. I test the idea that forgetting affords literal experiences of mnemonic absences by considering different views of absence perception and I evaluate whether the objections raised against Farennikova’s approach also apply to my exploratory idea. I show that, while the idea resists the objections that an advocate of a cognitive approach to mnemonic absences may raise, the same does not apply to those elaborated by advocates of a metacognitive approach. Even if conceiving of occurrent states of forgetting as literal experiences of mnemonic absences sounds appealing, this idea is misleading. Therefore, I suggest conceiving of occurrent states of forgetting as states with metacognitive features, which track the absence of episodic memories from awareness in an affectively mediated way.

An account of the development of temporal understanding is proposed which links such understanding with the development of episodic memory. We distinguish between different ways of representing time in terms of the kinds of temporal frameworks they involve. Distinctions are made between frameworks that are perspectival or nonperspectival and those that represent recurrent sequences or particular times. Even primitive temporal understanding integrates both perspectival and nonperspectival components. However, since early frameworks are event-based and localized, they are not yet (...) sufficient for episodic memory in that they do not enable the child to think of events as having occurred at particular points in time. We describe the emergence of new kinds of frameworks in terms of the development of temporal decentering. Two levels of temporal decentering are distinguished, with the higher level involving an appreciation of how event representations depend on one's temporal perspective. (shrink)

Whether non-human animals can have episodic memories remains the subject of extensive debate. A number of prominent memory researchers defend the view that animals do not have the same kind of episodic memory as humans do, whereas others argue that some animals have episodic-like memory—i.e., they can remember what, where and when an event happened. Defining what constitutes episodic memory has proven to be difficult. In this paper, I propose a dual systems (...) account and provide evidence for a distinction between event memory and episodic memory. Event memory is a perceptual system that evolved to support adaptive short-term goal processing, whereas episodic memory is based on narratives, which bind event memories into a retrievable whole that is temporally and causally organized around subject’s goals. I argue that carefully distinguishing event memory from episodic memory can help resolve the debate. (shrink)

The debate over the objects of episodic memory has for some time been stalled, with few alternatives to familiar forms of direct and indirect realism being advanced. This paper moves the debate forward by building on insights from the recent psychological literature on memory as a form of episodic hypothetical thought (or mental time travel) and the recent philosophical literature on relationalist and representationalist approaches to perception. The former suggests that an adequate account of the objects (...) of episodic memory will have to be a special case of an account of the objects of episodic hypothetical thought more generally. The latter suggests that an adequate account of the objects of episodic hypothetical thought will have to combine features of direct realism and representationalism. We develop a novel pragmatist-inspired account of the objects of episodic hypothetical thought that has the requisite features. (shrink)

The prevailing view about our memory skills is that they serve a complex epistemic function. I shall call this the “monistic view.” Instead of a monistic, exclusively epistemic approach, I propose a transactional view. On this approach, autobiographical memory is irreducible to the epistemic functions of episodic memory because of its essentially moral and empathic character. I argue that this transactional view provides a more plausible and integral account of memory capacities in humans, based on (...) theoretical and empirical reasons. Memory, on this account, plays two distinctive roles. The episodic memory system satisfies epistemic needs and is valuable because it is a source of justification for beliefs about the past. Autobiographical memory satisfies moral and narrative-autonoetic needs, and is valuable because it is a source of personally meaningful and insightful experiences about our past. Unlike autobiographical memory, episodic memory is only weakly autonoetic. The relation between these two roles of memory is captured by the tension between a narrative and an accurate report.

The paper focuses on the particular structure of the content of so-called generic memories, specifically of those of recurring events from one's past. This way of remembering has two central features that are in tension to each other: what is mentally represented is both rather specific as one is typically simulating a scene and sufficiently abstract as the represented scene stands for a series of similar former events. It will be argued that the phenomenon can be adequately described as a (...) mental state representing personal event prototypes. This description further allows to account for the dynamic process of remembering, in which, depending on the context, different forms of personal remembering may come to the fore. (shrink)

Psychological research has discovered that episodic memories are constructive in nature. This paper examines how, despite being constructive, episodic memories can provide us with justification for beliefs about the past. In current literature, two major approaches to memorial justification are internalist foundationalism and reliabilism. I first demonstrate that an influential version of internalist foundationalism, dogmatism, encounters problems when we compare certain types of memory construction with cognitive penetration in perception. On the other hand, various versions of reliabilism (...) all face skeptical challenges. I propose an alternative, two-factor theory that recognizes an epistemic distinction typically overlooked by dogmatism and reliabilism. Although our account leaves certain aspects unspecified, it is an important step forward. (shrink)

The Galilean explanatory style is characterized by the search for the underlying structure of phenomena, the positing of "deep" explanatory principles, and a view of the relation between theory and data, on which the search for "crucial data" is of primary importance. In this paper, I trace the dynamics of adopting the Galilean style, focusing on the science of episodic memory. I argue that memory systems, such as episodic and semantic memory, were posited as underlying (...) competences producing the observable phenomena of memory. Considered in idealized isolation from other systems, episodic memory was taken to underlay the ability of individuals to remember events from their personal past. Yet, in reality, memory systems regularly interact, standing in many-to-many relations to actual memory tasks and experiences. Upon this backdrop, I explore a puzzle about the increasing prominence of the notion of autonoetic consciousness in Tulving's theory of episodic memory. I argue that, contrary to widespread belief, the prominence is not best explained by the purported essential link between autonoetic consciousness and episodic memory. Rather, it is explained by the fact that autonoetic consciousness, hypothesized to uniquely accompany episodic retrieval, was considered a source of crucial data, predictable only from theories positing a functionally distinct episodic memory system. However, with the emergence of a new generation of theories, positing wider memory systems for remembering and imagination, the question of the relation between episodic memory and autonoetic consciousness has been reopened. This creates a pressing need for de-idealization, triggering a new search for crucial data. (shrink)

Whether intentional suppression of an unpleasant or unwanted memory reduces the ability to recall that memory subsequently is a contested issue in contemporary memory research. Building on findings that similar processes are recruited when individuals remember the past and imagine the future, we measured the effects of thought suppression on memory for imagined future scenarios. Thought suppression reduced the ability to recall emotionally negative scenarios, but not those that were emotionally positive. This finding suggests that intentionally (...) avoiding thoughts about emotionally negative episodes may inhibit representations of those memories, progressively reducing their availability to recall.
