Memory trace was originally a philosophical term used to explain the phenomenon of remembering. Once debated by Plato, Aristotle, and Zeno of Citium, the notion seems more recently to have become the exclusive province of cognitive psychologists and neuroscientists. Nonetheless, this modern appropriation should not deter philosophers from thinking carefully about the nature of memory traces. On the contrary, scientific research on the nature of memory traces can rekindle philosopher's interest on this notion. With that general aim in mind, the (...) present paper has three specific goals. First, it attempts to chart the most relevant philosophical views on the nature of memory traces from both a thematic and historical perspective. Second, it reviews critical findings in the psychology and the neuroscience of memory traces. Finally, it explains how such results lend support to or discredit specific philosophical positions on the nature of memory traces. This paper also touches upon the issues raised by recent empirical research that theories of memory traces need to accommodate in order to succeed. (shrink)

What is collective about collective memory? Two different concepts of collective memory compete—one refers to the aggregation of socially framed individual memories and one refers to collective phenomena sui generis—though the difference is rarely articulated in the literature. This article theorizes the differences and relations between individualist and collectivist understandings of collective memory. The former are open to psychological considerations, including neurological and cognitive factors, but neglect technologies of memory other than the brain and the ways in which cognitive and (...) even neurological patterns are constituted in part by genuinely social processes. The latter emphasize the social and cultural patternings of public and personal memory, but neglect the ways in which those processes are constituted in part by psychological dynamics. This article advocates, through the example of traumatic events, a strategy of multidimensional rapprochement between individualist and collectivist approaches. (shrink)

This book offers original accounts of a number of central social phenomena, many of which have received little if any prior philosophical attention. These phenomena include social groups, group languages, acting together, collective belief, mutual recognition, and social convention. In the course of developing her analyses Gilbert discusses the work of Emile Durkheim, Georg Simmel, Max Weber, David Lewis, among others.

This book develops a novel approach to distributed cognition and collective intentionality. It is argued that collective mentality should be only be posited where specialized subroutines are integrated in a way that yields skillful, goal-directed behavior that is sensitive to concerns that are relevant to a group as such.

Real agents rely, when forming their beliefs, on imperfect informational sources (sources which deliver, even under normal conditions of operation, both accurate and inaccurate information). They therefore face the ‘endorsement problem’: how can beliefs produced by endorsing information received from imperfect sources be formed in an epistemically acceptable manner? Focussing on the case of episodic memory and drawing on empirical work on metamemory, this article argues that metacognition likely plays a crucial role in explaining how agents solve the endorsement problem.

Elements of Episodic Memory is a classic text in the psychology literature. It had a significant influence on research in the area has been much sought after in recent years. Finally, it has now been made available again with this reissue, the text unchanged from the original.

The Collective Memory Reader provides a wide array of texts that underwrite the field of memory studies. Taken together, these seminal texts, hard-to-find classics, previsouly untranslated material, unusual extensions, and contemporary landmarks provide a definitive entry point into the field for students and an essential resource for scholars.

Numerous philosophical theories of joint agency and its intentional structure have been developed in the past few decades. These theories have offered accounts of joint agency that appeal to higher-level states that are?shared? in some way. These accounts have enhanced our understanding of joint agency, yet there are a number of lower-level cognitive phenomena involved in joint action that philosophers rarely acknowledge. In particular, empirical research in cognitive science has revealed that when individuals engage in a joint activity such as (...) conversation or joint problem solving, they become aligned at multiple levels. We argue that this phenomenon of alignment is crucial to understanding joint actions and should be integrated with philosophical approaches. In this paper, we sketch a possible integration, and draw out its implications for understanding of joint agency and collective intentionality. The result is a process-based, dynamic account of joint action that integrates both low-level and high-level states, and seeks to capture the separate processes of how a joint action is initiated and sustained.

Are companies, churches, and states genuine agents? Or are they just collections of individuals that give a misleading impression of unity? This question is important, since the answer dictates how we should explain the behaviour of these entities and whether we should treat them as responsible and accountable on the model of individual agents. Group Agency offers a new approach to that question and is relevant, therefore, to a range of fields from philosophy to law, politics, and the social sciences. (...) Christian List and Philip Pettit argue that there really are group or corporate agents, over and above the individual agents who compose them, and that a proper approach to the social sciences, law, morality, and politics must take account of this fact. Unlike some earlier defences of group agency, their account is entirely unmysterious in character and, despite not being technically difficult, is grounded in cutting-edge work in social choice theory, economics, and philosophy.

Transactive memory theory describes the processes by which benefits for memory can occur when remembering is shared in dyads or groups. In contrast, cognitive psychology experiments demonstrate that social influences on memory disrupt and inhibit individual recall. However, most research in cognitive psychology has focused on groups of strangers recalling relatively meaningless stimuli. In the current study, we examined social influences on memory in groups with a shared history, who were recalling a range of stimuli, from word lists to personal, (...) shared memories. We focused in detail on the products and processes of remembering during in-depth interviews with 12 older married couples. These interviews consisted of three recall tasks: (1) word list recall; (2) personal list recall, where stimuli were relevant to the couples’ shared past; and (3) an open-ended autobiographical interview. We conducted these tasks individually and then collaboratively two weeks later. Across each of the tasks, although some couples demonstrated collaborative inhibition, others demonstrated collaborative facilitation. We identified a number of factors that predicted collaborative success, in particular, group-level strategy use. Our results show that collaboration may help or hinder memory, and certain interactions are more likely to produce collaborative benefits. (shrink)

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)

In this paper, we aim to show that the framework of embedded, distributed, or extended cognition offers new perspectives on social cognition by applying it to one specific domain: the psychology of memory. In making our case, first we specify some key social dimensions of cognitive distribution and some basic distinctions between memory cases, and then describe stronger and weaker versions of distributed remembering in the general distributed cognition framework. Next, we examine studies of social influences on memory in cognitive (...) psychology, and identify the valuable concepts and methods to be extended and embedded in our framework; we focus in particular on three related paradigms: transactive memory, collaborative recall, and social contagion. Finally, we sketch our own early studies of individual and group memory developed within our framework of distributed cognition, on social contagion of autobiographical memories, collaborative flashbulb memories, and memories of high school at a high school reunion. We see two reciprocal benefits of this conceptual and empirical framework to social memory phenomena: that ideas about distributed cognition can be honed against and tested with the help of sophisticated methods in the social cognitive psychology of memory; and conversely, that a range of social memory phenomena that are as yet poorly understood can be approached afresh with theoretically motivated extensions of existing empirical paradigms.

The goal of this chapter is to describe recollective memory and give an account of some of the characteristics of this form of human memory. I take recollective memory to be the type of memory that occurs when an individual recalls a specific episode from their past experience. I start with this very loose definition because a large part of this chapter consists of an attempt to work out a more detailed and analytic description of this form of memory.

I introduce the seven papers in this special issue, by Andy Clark, Je´roˆme Dokic, Richard Menary, Jenann Ismael, Sue Campbell, Doris McIlwain, and Mark Rowlands. This paper explains the motivation for an alliance between the sciences of memory and the extended mind hypothesis. It examines in turn the role of worldly, social, and internalized forms of scaffolding to memory and cognition, and also highlights themes relating to affect, agency, and individual differences.

While memory is conceptualized predominantly as an individual capacity in the cognitive and biological sciences, the social sciences have most commonly construed memory as a collective phenomenon. Collective memory has been put to diverse uses, ranging from accounts of nationalism in history and political science to views of ritualization and commemoration in anthropology and sociology. These appeals to collective memory share the idea that memory ‘‘goes beyond the individual’’ but often run together quite different claims in spelling out that idea. (...) This paper reviews a sampling of recent work on collective memory in the light of emerging externalist views within the cognitive sciences, and through some reflection on broader traditions of thought in the biological and social sciences that have appealed to the idea that groups have minds. The paper concludes with some thoughts about the relationship between these kinds of cognitive metaphors in the social sciences and our notion of agency. (shrink)

Episodic memory is a major area of research in psychology. Initially viewed as a distinct store of information derived from experienced episodes, episodic memory is understood today as a form of mental "time travel" into the personal past. Recent research has revealed striking similarities between episodic memory - past-oriented mental time travel - and future-oriented mental time travel (FMTT). Seeing the Future: Theoretical Perspectives on Future-Oriented Mental Time Travel brings together leading contributors in both empirical and theoretical disciplines to present (...) the first interdisciplinary look at the human to imagine future scenarios. Chapters focus on the challenging conceptual and theoretical questions raised by FMTT, covering themes such as: varieties of future-oriented cognition; relationships between FMTT and episodic memory; subjective temporality in FMTT; the self in FMTT; and functional, evolutionary and comparative, developmental, and clinical perspectives on FMTT. With its focus on the conceptual issues at the heart of fast-developing research on FMTT, this edited volume will serve graduate students to senior scholars working on or interested in FMTT and related areas as a synthesis of current theoretical thinking and a source of questions for future FMTT research.

Memory has long been a subject of fascination for poets, artists, philosophers and historians. The volume examines how past events are remembered, contested, forgotten, learned from and shared with others. Each author in The Ashgate Research Companion to Memory Studies has been asked to reflect on his or her research companions as a scholar, who studies memory. The original studies presented in the volume are written by leading experts, who emphasize both the continuity of heritage and tradition, as well as (...) the memory of hostilities, traumas and painful events. Comprised of four thematic sections, The Ashgate Research Companion to Memory Studies provides a comprehensive overview of the latest research within the discipline. The principal themes include: ¢ Memory, History and Time ¢ Social, Psychological and Cultural Frameworks of Memory ¢ Acts and Places of Memory ¢ Politics of Memory, Forgetting and Democracy.

Collaborative remembering, in which two or more individuals cooperate to remember together, is an ordinary occurrence. Ordinary though it may be, it challenges traditional understandings of remembering as a cognitive process unfolding within a single subject, as well as traditional understandings of memory knowledge as a justified memory belief held within the mind of a single subject. Collaborative memory has come to be a major area of research in psychology, but it has so far not been investigated in epistemology. In (...) this chapter, we attempt an initial exploration of the epistemological implications of collaborative memory research, taking as our starting point the “extended knowledge” debate which has resulted from the recent encounter between extracranialist theories of cognition and externalist theories of knowledge (Carter et al., 2014; Carter et al., forthcoming). Various forms of socially and technologically augmented memory have played important roles in the extended knowledge debate, but the debate has so far not taken collaborative memory, in particular, into account. We will argue that collaborative memory supports a novel externalist theory of knowledge: distributed reliabilism. Distributed reliabilism departs in two important respects from both traditional reliabilism (Goldman, 2012) and updated theories such as extended (Goldberg, 2010) and social reliabilism (Goldman, 2014). First, it acknowledges that belief-forming processes may extend extracranially to include processing performed both by other subjects and by technological artifacts. Second, it acknowledges that distributed sociotechnical systems themselves may be knowing subjects. Overall, then, the main aim of the chapter is to draw out the philosophical implications of psychological research on collaborative memory. But our argument will also suggest that it may be useful to broaden the standard conception of collaborative memory to include not only the sorts of direct interactions among subjects that have been the focus of psychological research so far but also a range of more indirect, technology-supported and -mediated interactions, and it thus has implications for psychology as well.

In this paper, I describe and discuss two mental phenomena which are somewhat neglected in the philosophy of mind: focused daydreaming and mind-wandering. My aim is to show that their natures are rather distinct, despite the fact that we tend to classify both as instances of daydreaming. The first difference between the two, I argue, is that, while focused daydreaming is an instance of imaginative mental agency, mind-wandering is not—though this does not mean that mind-wandering cannot involve mental agency at (...) all. This personal-level difference in agency and purposiveness has, furthermore, the consequence that instances of mind-wandering do not constitute unified and self-contained segments of the stream of consciousness—in stark contrast to focused daydreams. Besides, the two kinds of mental phenomena differ in whether they possess a narrative structure, and in how we may make sense of the succession of mental episodes involved. (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.

The Archival and Constructive views of memory offer contrasting characterizations of remembering and its relation to memory errors. I evaluate the descriptive adequacy of each by offering a close analysis of one of the most prominent experimental techniques by which memory errors are elicited—the Deese-Roediger-McDermott paradigm. Explaining the DRM effect requires appreciating it as a distinct form of memory error, which I refer to as misremembering. Misremembering is a memory error that relies on successful retention of the targeted event. It (...) differs from both successful remembering and from confabulation errors, where the representation produced is wholly inaccurate. As I show, neither the Archival nor the Constructive View can account for the DRM effect because they are insensitive to misremembering’s unique explanatory demands. Fortunately, the explanatory limitations of the Archival and Constructive Views are complementary. This suggests a way.. (shrink)

Philosophy and Memory Traces defends two theories of autobiographical memory. One is a bewildering historical view of memories as dynamic patterns in fleeting animal spirits, nervous fluids which rummaged through the pores of brain and body. The other is new connectionism, in which memories are 'stored' only superpositionally, and reconstructed rather than reproduced. Both models, argues John Sutton, depart from static archival metaphors by employing distributed representation, which brings interference and confusion between memory traces. Both raise urgent issues about control (...) of the personal past, and about relations between self and body. Sutton demonstrates the role of bizarre body fluids in moral physiology, as philosophers from Descartes and Locke to Coleridge struggled to control their own innards and impose cognitive discipline on 'the phantasmal chaos of association'. Going on to defend connectionism against Fodor and critics of passive mental representations, he shows how problems of the self are implicated in cognitive science. (shrink)

Despite an explosion of studies on memory in historical and cultural studies, there is relatively little in moral philosophy on this subject. In this book, Jeffrey Blustein provides a systematic and philosophically rigorous account of a morality of memory. Drawing on a broad range of philosophical and humanistic literatures, he offers a novel examination of memory and our relations to people and events from our past, the ways in which memory is preserved and transmitted, and the moral responsibilities associated with (...) it. Blustein treats topics of responsibility for one's own past; historical injustice and the role of memory in doing justice to the past; the relationship of collective memory to history and identity; collective and individual obligations to remember those who have died, including those who are dear to us; and the moral significance of bearing witness.

Sometimes I remember my past experiences from an ‘observer’ perspective, seeing myself in the remembered scene. This paper analyses the distinction in personal memory between such external observer visuospatial perspectives and ‘field’ perspectives, in which I experience the remembered actions and events as from my original point of view. It argues that Richard Wollheim’s related distinction between centred and acentred memory fails to capture the key phenomena, and criticizes Wollheim’s reasons for doubting that observer ‘memories’ are genuine personal memories. Since (...) field perspectives in personal memory are also likely to be the product of constructive processes, we should reject the common assumption that such constructive processes inevitably bring distortion and error. Yet field perspectives tend to be treated as privileged also in the domains of memory for skilled movement, and memory for trauma. In each case, it is argued that visuospatial perspective in personal memory should be distinguished from other kinds of perspective such as kinesthetic perspective and emotional perspective.

In the social sciences and in everyday speech we often talk about groups as if they behaved in the same way as individuals, thinking and acting as a singular being. We say for example that "Google intends to develop an automated car", "the U.S. Government believes that Syria has used chemical weapons on its people", or that "the NRA wants to protect the rights of gun owners". We also often ascribe legal and moral responsibility to groups. But could groups literally (...) intend things? Is there such a thing as a collective mind? If so, should groups be held morally responsible? Such questions are of vital importance to our understanding of the social world. In this lively, engaging introduction Deborah Tollefsen offers a careful survey of contemporary philosophers? answers to these questions, and argues for the unorthodox view that certain groups should, indeed, be treated as agents and deserve to be held morally accountable. Tollefsen explores the nature of belief, action and intention, and shows the reader how a belief in group agency can be reconciled with our understanding of individual agency and accountability. _Groups as Agents_ will be a vital resource for scholars as well as for students of philosophy and the social sciences encountering the topic for the first time.

Continuists maintain that, aside from their distinct temporal orientations, episodic memory and future-oriented mental time travel (FMTT) are qualitatively continuous. Discontinuists deny this, arguing that, in addition to their distinct temporal orientations, there are qualitative metaphysical or epistemological differences between episodic memory and FMTT. This chapter defends continuism by responding both to arguments for metaphysical discontinuism, based on alleged discontinuities between episodic memory and FMTT at the causal, intentional, and phenomenological levels, and to arguments for epistemological discontinuism, based on alleged (...) discontinuities with respect to the epistemic openness of the past and future, the directness or indirectness of our knowledge of past and future, and immunity to error through misidentification. The chapter concludes by sketching a positive argument for continuism. (shrink)

The existence of group agents is relatively widely accepted. Examples are corporations, courts, NGOs, and even entire states. But should we also accept that there is such a thing as group consciousness? I give an overview of some of the key issues in this debate and sketch a tentative argument for the view that group agents lack phenomenal consciousness. In developing my argument, I draw on integrated information theory, a much-discussed theory of consciousness. I conclude by pointing out an implication (...) of my argument for the normative status of group agents. (shrink)

Although mind-wandering occupies up to half of our waking thoughts, it is seldom discussed in philosophy. My paper brings these neglected thoughts into focus. I propose that mind-wandering is unguided attention. Guidance in my sense concerns how attention is monitored and regulated as it unfolds over time. Roughly speaking, someone’s attention is guided if she would feel pulled back, were she distracted from her current focus. Because our wandering thoughts drift unchecked from topic to topic, they are unguided. One motivation (...) for my theory is what I call the “Puzzle of the Purposeful Wanderer”. On the one hand, mind-wandering seems essentially purposeless; almost by definition, it contrasts with goal-directed cognition. On the other hand, empirical evidence suggests that our minds frequently wander to our goals. My solution to the puzzle is this: mind-wandering is purposeless in one way—it is unguided—but purposeful in another—it is frequently caused, and thus motivated, by our goals. Another motivation for my theory is to distinguish mind-wandering from two antithetical forms of cognition: absorption and rumination. Surprisingly, previous theories cannot capture these distinctions. I can: on my view, absorption and rumination are guided, whereas mind-wandering is not. My paper has four parts. Section 1 spells out the puzzle. Sections 2 and 3 explicate two extant views of mind-wandering—the first held by most cognitive scientists, the second by Thomas Metzinger. Section 4 uses the limitations of these theories to motivate my own: mind-wandering is unguided attention. (shrink)

Human beings act together in characteristic ways that matter to us a great deal. This book explores the conceptual, metaphysical and normative foundations of such sociality. It argues that appeal to the planning structures involved in our individual, temporally extended agency provides substantial resources for understanding these foundations of our sociality.

If you’re a materialist, you probably think that rabbits are conscious. And you ought to think that. After all, rabbits are a lot like us, biologically and neurophysiologically. If you’re a materialist, you probably also think that conscious experience would be present in a wide range of naturally-evolved alien beings behaviorally very similar to us even if they are physiologically very different. And you ought to think that. After all, to deny it seems insupportable Earthly chauvinism. But a materialist who (...) accepts consciousness in weirdly formed aliens ought also to accept consciousness in spatially distributed group entities. If she then also accepts rabbit consciousness, she ought to accept the possibility of consciousness even in rather dumb group entities. Finally, the United States would seem to be a rather dumb group entity of the relevant sort. If we set aside our morphological prejudices against spatially distributed group entities, we can see that the United States has all the types of properties that materialists tend to regard as characteristic of conscious beings.

The present paper offers a philosophical discussion of phenomena which in the empirical literature have recently been subsumed under the concept of ‘mental time travel’. More precisely, the paper considers differences and similarities between two cases of ‘mental time travel’, recollective memories (‘R-memories’) of past events on the one hand, and sensory imaginations (‘S-imaginations’) of future events on the other. It develops and defends the claim that, because a subject who R-remembers a past event is experientially aware of a past (...) particular event, while a subject who S-imagines a future event could not possibly be experientially aware of a future particular event, R-memories of past events and S-imaginations of future events are ultimately mental occurrences of two different kinds.

Philosophical theories of memory rarely distinguish between importantly different sorts of memory: procedural, semantic and episodic. I argue for a temporal representation theory to explain the unique characteristic of episodic memory as the only form of conscious memory. A careful distinction between implicit and explicit representation shows how the past figures in memory. In procedural and semantic memory, the influence of the past is implicit by which I mean that the past experience is used but not represented in the skill (...) or knowledge. Episodic memory, in contrast, depends on representing a past experience as past. On a temporal representation theory of consciousness, a conscious state represents the present moment, and in the case of episodic memory, it includes a representation of past experience. The embedded account of the ‘feeling of pastness’ takes past experience to be part of the explicit content of a conscious state. An episodic memory is a representation of the present that includes a representation of the past. Whereas a higher-order theory of consciousness can give no reason why only episodic memories are conscious, a temporal theory explains why episodic memories are both higher-order and conscious. Finally, I consider the essential role of episodic memory in the formation of a temporally extended self. The demands of a social environment motivate development of an ability to track the mental states of others and oneself over time. By incorporating past experience (and future experience) into the present, episodic memory extends experience in time to form the sense of self. Through a careful examination of the function of temporal representation, we can see why the past is not consciously represented in procedural and semantic memory and the value of consciously representing the past in episodic memory.

Misremembering is a systematic and ordinary occurrence in our daily lives. Since it is commonly assumed that the function of memory is to remember the past, misremembering is typically thought to happen because our memory system malfunctions. In this paper I argue that not all cases of misremembering are due to failures in our memory system. In particular, I argue that many ordinary cases of misremembering should not be seen as instances of memory’s malfunction, but rather as the normal result (...) of a larger cognitive system that performs a different function, and for which remembering is just one operation. Building upon extant psychological and neuroscientific evidence, I offer a picture of memory as an integral part of a larger system that supports not only thinking of what was the case and what potentially could be the case, but also what could have been the case. More precisely, I claim that remembering is a particular operation of a cognitive system that permits the flexible recombination of different components of encoded traces into representations of possible past events that might or might not have occurred, in the service of constructing mental simulations of possible future events.

This paper explores the implications of the psychology of constructive memory for philosophical theories of the metaphysics of memory and for a central question in the epistemology of memory. I first develop a general interpretation of the psychology of constructive memory. I then argue, on the basis of this interpretation, for an updated version of Martin and Deutscher's influential causal theory of memory. I conclude by sketching the implications of this updated theory for the question of memory 's status as (...) a generative epistemic source. (shrink)

As humans, we frequently engage in mental time travel, reliving past experiences and imagining possible future events. This study examined whether similar factors affect the subjective experience associated with remembering the past and imagining the future. Participants mentally “re-experienced” or “pre-experienced” positive and negative events that differed in their temporal distance from the present , and then rated the phenomenal characteristics associated with their representations. For both past and future, representations of positive events were associated with a greater feeling of (...) re-experiencing than representations of negative events. In addition, representations of temporally close events contained more sensorial and contextual details, and generated a stronger feeling of re-experiencing than representations of temporally distant events. It is suggested that the way we both remember our past and imagine our future is constrained by our current goals. (shrink)
