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)

We explore the role of episodic imagining in explaining why people both differentially report that it seems to them in experience as though time robustly passes, and why they differentially report that they believe that time does in fact robustly pass. We empirically investigate two hypotheses, the differential vividness hypothesis, and the mental time travel hypothesis. According to each of these, the degree to which people vividly episodically imagine past/future states of affairs influences their tendency to report that it seems (...) to them as though time robustly passes and to judge that time does robustly pass. According to the former, a greater degree of vividness will tend to increase the extent to which people make such reports, while according to the latter, it will tend to decrease the extent to which people make such reports. We found weak evidence in favour of the former hypothesis. We reflect on the implications of this finding for theorising about such reports. (shrink)

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.

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.

In the literature on episodic memory, one claim that has been made by a number of psychologists, and that is also at least implicit in some of the accounts given by philosophers, is that being able to recollect particular past events in the distinctive way afforded by episodic memory requires the possession of aspects of a theory of mind, such as a grasp of the relationship between one’s present recollective experience and one’s own past perceptual experience of the remembered event. (...) In this paper, I re-examine what connection, if any, there is between episodic memory and theory of mind. I first criticize the dominant way in which this connection has been construed theoretically, which – perhaps influenced by other aspects of theory of mind research – has sought to link the possession of episodic memory primarily with a grasp of the idea of representation, or the idea of informational access. I then argue for a novel, alternative, way of connecting episodic memory and theory of mind, which focuses on the category of an experience, and on the role a grasp of that category might be seen to play in episodic recollection. In doing so, I also draw attention to a dimension of our understanding of the mental which remains as yet underexplored in the literature on theory of mind. (shrink)

By utilizing new information from both clinical and experimental (lesion, electrophysiological, and gene-activation) studies with animals, the anatomy underlying anterograde amnesia has been reformulated. The distinction between temporal lobe and diencephalic amnesia is of limited value in that a common feature of anterograde amnesia is damage to part of an comprising the hippocampus, the fornix, the mamillary bodies, and the anterior thalamic nuclei. This view, which can be traced back to Delay and Brion (1969), differs from other recent models in (...) placing critical importance on the efferents from the hippocampus via the fornix to the diencephalon. These are necessary for the encoding and, hence, the effective subsequent recall of episodic memory. An additional feature of this hippocampalanterior thalamic and the perirhinal–medial dorsal thalamic systems are compromised, leading to severe deficits in both recall and recognition. (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)

The questions of whether episodic memory is a propositional attitude, and of whether it has propositional content, are central to discussions about how memory represents the world, what mental states should count as memories, and what kind of beings are capable of remembering. Despite its importance to such topics, these questions have not been addressed explicitly in the recent literature in philosophy of memory. In one of the very few pieces dealing with the topic, Fernández (2006) provides a positive answer (...) to the initial questions by arguing that the propositional attitude view of memory, as I will call it, provides a simple account of how memory possesses truth-conditions. A similar suggestion is made by Byrne (2010) when he proposes that perception and episodic memory have the same kind of content, differing only in degree. Against the propositional attitude view, I will argue that episodic memory does not have propositional content, and therefore, that it is not a propositional attitude. My project here is, therefore, mainly critical. I will show that, if empirical work is to inform our philosophical theories of memory in any way, we have good reasons to deny, or at least to be skeptical, of the prospects of the propositional attitude view of episodic memory.

Although episodic memory is a widely studied form of memory both in philosophy and psychology, it still raises many burning questions regarding its definition and even its acceptance. Over the last two decades, cross-disciplinary discussions between these two fields have increased as they tackle shared concerns, such as the phenomenology of recollection, and therefore allow for fruitful interaction. This editorial introduction aims to provide a comprehensive and up-to-date presentation of the main existing conceptions and issues on the topic. After delineating (...) Tulving’s chief theoretical import and multifaceted legacy, it goes on to chart the different attempts to capture the episodicity feature of memory according to three categories: a first approach aims to show the cognitive abilities required for a subject to episodically remember; the second defines episodicity as a stage-specific feature; the last explains episodicity in terms of the epistemological properties of episodic memory. This state of the art thereby sets the stage for the contributions of the present volume, which will be introduced in conclusion. (shrink)

Recently, a research program has emerged that aims to show that animals have a memory capacity that is similar to the human episodic memory capacity. Researchers within this program argue that nonhuman animals have episodic-like memory of personally experienced past events. In this paper, I specify and evaluate the goals of this research program and the progress it has made in achieving them. I will examine some of the data that the research program has produced, as well as the operational (...) definitions and assumptions that have gone into producing that data, in order to call into question the ultimate value of the episodic-like memory research program. I argue that there is a gap between the claims that the research program makes and the data it uses to support these claims, and that bridging this gap is essential if we want to claim that human episodic memory has a meaningful analog in animals. I end with some suggestions of how to potentially fix these problems. (shrink)

This paper offers a modeling account of episodic representation. I argue that the episodic system constructsmental models: representations that preserve the spatiotemporal structure of represented domains. In prototypical cases, these domains are events: occurrences taken by subjects to have characteristic structures, dynamics and relatively determinate beginnings and ends. Due to their simplicity and manipulability, mental event models can be used in a variety of cognitive contexts: in remembering the personal past, but also in future-oriented and counterfactual imagination. As structural representations, (...) they allow surrogative reasoning, supporting inferences about their constituents which can be used in reasoning about the represented events. (shrink)

What is it to remember an episode from one’s past? How does episodic memory give us knowledge of the personal past? What explains the emergence of the apparently uniquely human ability to relive the past? Drawing on current research on mental time travel, this book proposes an integrated set of answers to these questions, arguing that remembering is a matter of simulating past episodes, that we can identify metacognitive mechanisms enabling episodic simulation to meet standards of reliability sufficient for knowledge, (...) and that the subjective experience of reliving the past is a precondition for the reliability of simulational remembering. The resulting account of memory, memory knowledge, and their evolution will be of interest both to philosophers interested in empirically-informed approaches to memory and to psychologists interested in the philosophical implications of empirical memory research.

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)

Philosophical work comes in different sizes: there are systemic treatises, monographic surveys, philosopher-expanding texts. But there is also room for smaller studies that focus on highly particularized ideas and issues: studies that deal not with entire continents but with mere reefs and estuaries. The present essays are of this limited nature. Their aim is less to give a view of the overall lay of the land than to give a tranistic view of the diversity of the landscape. The present book (...) continues RescherOCOs longstanding practice of publishing groups of philosophical essays that originated in occasional lecture and conference presentations. Notwithstanding their topical diversity the essays exhibit a uniformity of method in a common attempt to view historically significant philosophical issues in the light of modern perspectives opened up thorough conceptual clarification.".

In recent years, there has been an increasing interest among philosophers of memory in the questions of how to characterize and to account for the temporal phenomenology of episodic memory. One prominent suggestion has been that episodic memory involves a feeling of pastness, the elaboration of which has given rise to two main approaches. On the intentionalist approach, the feeling of pastness is explained in terms of what episodic memory represents. In particular, Fernández has argued that it can be explained (...) in terms of memory representing itself as being caused by a past perceptual experience. On the metacognitive approach, which we have recently developed in, the feeling of pastness results from the monitoring and interpretation of the processing features of episodic remembering. In this paper, we show that the metacognitive approach should be preferred over the intentionalist approach. We argue that intentionalism, and Fernández’ causal self-referential view in particular, ultimately fail as accounts of the feeling of pastness. The difficulties faced by intentionalism allows us to single out three constraints that any satisfactory account of the temporal phenomenology of episodic remembering needs to meet. We conclude by arguing that the metacognitive view satisfies those constraints in a neat way, and as such, that it should be preferred over intentionalism. (shrink)

This edited volume considers the ways in which multiple stages, phases, or periods in an artistic or design process have served to arrive at the final artefact, with a focus on the meaning and use of the iteration, over the end result. In examining iteration, this collection of essays seeks to explore ways of theorising ideas surrounding series of objects, whether the original, the unfinished, the interim object, or the copy, vis-à-vis antecedents and successive exemplars. It asks how a closer (...) look at iterations of a single object-type - whether art, architecture, or design - might reveal new insight into the production of other objects and the production of thought alike. Written by an international team of contributors, offering a range of perspectives, it will look broadly at meaning and insight offered by the iteration, the multiple, and the design process, for historical research and its methods.

Direct realists about episodic memory claim that a rememberer has direct contact with a past event. However, how is it possible to be acquainted with an event that ceased to exist? That is 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 is 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 pay to hold direct realist intuitions about memory. Although I agree with these critics, I will make two claims. 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)

I present Ned Markosian's episodic account of identity under a sortal, and then use it to sketch a new model of the Trinity. I show that the model can be used to solve at least three important Trinitarian puzzles: the traditional ‘logical problem of the Trinity’, a less-discussed problem that has been dubbed the ‘problem of triunity’, and a problem about the divine processions that has been enjoying increased attention in the recent literature.

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)

The claim that episodic memory is immune to error through misidentification enjoys continuing popularity in philosophy. Psychological research on observer memory—usually defined as occurring when one remembers an event from a point of view other than that that from which he originally experienced it—would seem, on the face of it, to undermine the IEM claim. Relying on a certain view of memory content, Fernández, however, has provided an ingenious argument for the view that it does not. This paper reconstructs Fernández’ (...) argument and shows that there is reason to reject the definition of observer memory and the view of memory content on which it relies. Once these are rejected, it turns out that observer memory does indeed imply that the IEM claim is false. (shrink)

Autobiographical memory and the self are closely linked. AM retrieval in depression is characterized by a lack of specificity, suggesting an impairment of episodic AM. Autonoetic consciousness and self-perspective, which are critical to episodic AM, have never been addressed in depression. Twenty-one depressed inpatients and 21 matched controls were given an episodic AM task designed to assess positive and negative memories regarding specificity, autonoetic consciousness , and self-perspective . For specificity, “remember”, and “field” responses, ANOVAs revealed a main group effect (...) and a group × valence interaction. Between groups, patients showed lower scores than controls for positive memories. Within groups, patients showed greater scores for negative memories, and controls showed greater scores for positive memories. There is a global episodic AM impairment of positive memories in depression regarding specificity, autonoetic consciousness, and self-perspective. Our results suggest new cognitive interventions to improve the self-relevance of positive memories in depression. (shrink)

This article investigates account episodes in Italian family dinner conversations and illustrates how sequential patterns and participation are organized in terms of preferences indexical of moral ideology and moral order. Accounts have been mostly examined as speech acts abstracted from embedding sequential environment; this article shows that different design features of the priming move in account episodes retrospectively define different aspects of a situation as problematic and prospectively activate the relevance for distinctive remedial moves. On an ideological level, narrative elicitations (...) as priming moves and accounts as remedial moves index a moral perspective that promotes moral reasoning and thus the negotiation of norms. In addition, such moves realize a practice of morality that tends to be inquisitory vs condemnatory, offering the benefit of the doubt prior to guilt allocation. In conclusion, the discursive mechanics of accountability constitutes a medium for reproduction of, and innovation in, the moral order. (shrink)

The pressures that led to the evolution of episodic memory have recently seen much discussion, but a fully satisfactory account of them is still lacking. We seek to make progress in this debate by taking a step backward, identifying four possible ways that episodic memory could evolve in relation to simulationist future planning—a similar and seemingly related ability. After distinguishing each of these possibilities, the paper critically discusses existing accounts of the evolution of episodic memory. It then presents a novel (...) argument in favor of the view that episodic memory is a by-product of the evolution of simulationist future planning. The paper ends by showing that this position allows for the maintenance of the traditional view that episodic memory operates on stored memory traces, as well as explaining a number of key features of episodic memory: its being subject to frequent and systematic errors, its neural co-location with the capacity for simulationist future planning, and the potential existence of non-human episodic memory.

The ability to imagine hypothetical events in one’s personal future is thought to involve a number of constituent cognitive processes. We investigated the extent to which individual differences in working memory capacity contribute to facets of episodic future thought. College students completed simple and complex measures of working memory and were cued to recall autobiographical memories and imagine future autobiographical events consisting of varying levels of specificity . Consistent with previous findings, future thought was related to analogous measures of autobiographical (...) memory, likely reflecting overlapping cognitive factors supporting both past and future thought. Additionally, after controlling for autobiographical memory, residual working memory variance independently predicted future episodic specificity. We suggest that when imagining future events, working memory contributes to the construction of a single, coherent, future event depiction, but not to the retrieval or elaboration of event details.

There are logical and empirical grounds that link episodic memory and the ability to imagine future events. In some sense, both episodic memory and episodic foresight may be regarded as two sides of the same capacity to travel mentally in time. After reviewing some of the recent evidence for commonalities, I discuss limits of these parallels. There are fundamental differences between thinking about past and future events that need to be kept in clear view if we are to make progress (...) in understanding the nature of mental time travel. The reviewed evidence suggests that mental time travel is based on a complex system selected not for accuracy about past and future per se, but for fitness benefits. Functional analyses promise to lead to fruitful avenues for future research. (shrink)

Logical Investigations (notably, The Thought) is one of the works wherein Frege voices his hostility to psychologism in logic, science, and semantics. Such hostility lies, arguably, behind his threefold conceptual distinction between thought (Gedanke), thinking (Denken), and ideas (Vorstellungen). In this essay I investigate, to begin with, Frege’s motivations for drawing the distinction and keeping thinking episodes (one of the meanings of ‘thoughts’ in English) out of the picture. It turns out, or so I argue, that psychologism threatens, on Frege’s (...) view, to destroy the objectivity requirement by which thoughts are defined as answerable contents. I then draw a connection between this feature in Frege’s view and an on-going debate in philosophy of mind and language over the nature of world-directed thoughts and show that the feature lies at the heart of the singularist stance. Finally, I show that, despite Frege’s own hostility to all that bears the mark of the subjective in logic, science, and semantics, a psychological argument can be mounted in support of singularism (i.e. the view that some of our thoughts are about particulars qua particulars) using his disparaged notion of idea (Vorstellung) and that, appearances notwithstanding, the argument is compatible with the objectivity requirement on answerable thought-contents.

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)

Recent work on the early development of episodic memory in my laboratory has been fuelled by the following assumption: if episodic memory is re-experiential memory then Kant’s analysis of the spatiotemporal nature of experience should constrain and positively influence theories of episodic memory development. The idea is that re-experiential memory will “inherit” these spatiotemporal features. On the basis of this assumption, Russell and Hanna (Mind and Language 27(1):29–54, 2012) proposed that (a) the spatial element of re-experience is egocentric and (b) (...) that the temporal element of re-experiencing involves order/simultaneity. The first of these assumptions is immediately problematic for two reasons. In the first place, if we assume that early episodic recall mediated by processing in the hippocampus, then (a) is clearly in tension with the fact that spatial coding in the hippocampus is allocentric/environment-centred. Second, two of our own recent experiments (described here) show that when only egocentric cues are available in a What/When/Where episodic memory task it is not possible to distinguish young children’s performance from semantic memory. I argue that this tension should be resolved by recognising that the egocentric coding of the original experience as being of an objective scene relies upon allocentric representations and these are preserved in re-experiential memory, allowing a recollection of the objective nature of the scene on which one takes a subjective view.

Our thinking often uses rich memories of particular past events. Yet frequently we would do better to use other forms of memory. I show that existing accounts of the function of episodic memory cannot account for such cases, then develop an account which can. Roughly: rich representations of particular past events are required for Unrestricted Learning, learning which is not limited in how much of the world’s complexity it can capture; and episodic memory’s selection for Unrestricted Learning could explain its (...) ubiquitous (and often inappropriate) use for other tasks. This proposal suggests many avenues for further empirical and computational research. (shrink)

This study attempts to integrate linguistic and discourse analysis to investigate the way narrators demarcate episodic boundaries in conversational settings and hypothesize about the kind of cognitive processes that might be involved in such an activity. In contrast to previous research in this area which predominately relies on experimentally designed text, this study draws on naturalistic data and relies on the notion that narrators in conversational setting interactionally create narrative by recruiting discourse skills that are most readily available to them. (...) The study reveals that narrators in conversational settings employ reference and macropropositions following a general pattern. Generally, episode boundaries are marked both by macropropositions and full noun phrases. Noun phrases are often used to indicate the beginning of an episode, whereas pronominals are often used within episode boundaries suggesting the continuation of the current episode. The co-occurrence of macropropositions and NPs in demarcating episodic boundaries reflects the bidirectional process operating simultaneously within the linguistic and conceptual domains that is involved in the production of narratives. The use of pronominals within the episode boundaries indicates that cognitive mechanisms such as sustaining attention is also involved in demarcation of episodic boundaries. (shrink)

We argue that objectivity is acquired by learning to refer to particular situations, that is, by developing episodicity. This contrasts with the widespread idea that genericity is crucial in developing humans’ ability to conceive of an objective world. According to the collective intentionality account, objectivity is acquired by contrasting one’s particular perspective in the “here and now” with a generic group perspective on how things are generally. However, this line of argument rests on confusing two independent notions of genericity: (...) social and worldly genericity. Holding these two notions apart shows that there is no coherent developmental route from episodicity to objectivity via genericity. In effect, the collective intentionality account presupposes objectivity. Alternatively, episodicity may develop by enculturation into the common practice of spatial-indexical use. This ability establishes an initial, socially shared spatiotemporal reference system comprising the basis for objectivity. (shrink)

The ability to reflect on and monitor memory processes is one of the most investigated metamemory functions, and one of the important ways consciousnesses interacts with memory. The feeling-of-knowing is one task used to evaluate individual’s capacity to monitor their memory. We examined this reflective function of metacognition in older adults. We explored the contribution of metacognition to episodic memory impairment, in relation to the idea that older adults show a reduction in memory awareness characteristic of episodic memory. A first (...) experiment showed that age affects the accuracy of FOK when predictions are made on an episodic memory task but not on a semantic memory task, suggesting a particular role for episodic memory awareness in metacognitive evaluations. A second experiment showed that the age-difference in episodic FOK accuracy was removed if one took into account subjective reports of memory awareness, or recollection. We argue that the FOK deficit specific to episodic memory is based on a lack of memory awareness manifest as a recollection deficit. (shrink)

The term 'episodic memory' refers to our memory for unique, personal experiences, that we can date at some point in our past - our first day at school, the day we got married. It has again become a topic of great importance and interest to psychologists, neuroscientists, and philosophers. How are such memories stored in the brain, why do certain memories disappear (especially those from early in childhood), what causes false memories (memories of events we erroneously believe have really taken (...) place)? Since Endel Tulving's classic book 'Episodic memory' (OUP, 1983) very few books have been published on this topic. In recent years however, many of the assumptions made about episodic memory have had to be reconsidered as a result of new techniques, which have allowed us a far deeper understanding of episodic memory. In 'Episodic memory: new directions in research' three of the worlds leading researchers in the topic of memory have brought together a stellar team of contributors from the fields of cognitive psychology, neuropsychology, and neuroscience, to present an account of what we now know about about this fundamentally important topic. The list of contributors includes, amongst others, Daniel Schacter, Richard Morris, Fareneh Vargha-Khadem, and Endel Tulving. The work presented within this book will have a profound effect on the direction that future research in this topic will take. (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.

Episodic memory is the form of memory involved in remembering personally experienced past events. Here, I address two questions about episodic memory’s function: what does episodic memory do for us, and why do we have it? Recent work addressing these questions has emphasized episodic memory’s role in imaginative simulation, criticizing the mnemonic view on which episodic memory is “for” remembering. In this paper, I offer a defense of the mnemonic view by highlighting an underexplored mnemonic function of episodic memory – (...) namely, its role in the encoding, storage and retrieval of the type of information more standardly associated with semantic memory. I argue that in healthy individuals, episodic memory plays a central role in the encoding, storage and retrieval of prototypically semantic information, analogous to the role played by mind palaces in the method of loci, and may have been selected on for this reason. This suggests new directions for studying episodic memory, particularly in nonhuman animals. (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)
