We all seem to think that we do the acts we do because we consciously choose to do them. This commonsense view is thrown into dispute by Benjamin Libet's eyebrow-raising experiments, which seem to suggest that conscious will occurs not before but after the start of brain activity that produces physical action.

When entering an environment, animals – including humans – tend to consult their memories to determine what they know about the place. This information is useful to determine: is this place safe? And what happens next? In this chapter, we argue on both empirical and conceptual grounds that memory is largely organized by space. Spatial relations determine what is recalled and which experiences are combined in generalizations. Time does not play an analogous role. We show that space and time in (...) memory are thus deeply asymmetrical. We conclude with a consequence of our view: spatial organization entails a basic form of abstraction in a way temporal organization does not, and so the spatial organization of memory reveals that memory involves generalization from the very beginning.

Although the biological bases of forgetting remain obscure, the consensus among cognitive psychologists emphasizes interference processes, rejecting decay in accounting for memory loss. In contrast to this view, recent advances in understanding the neurobiology of long-term memory maintenance lead us to propose that a brain-wide well-regulated decay process, occurring mostly during sleep, systematically removes selected memories. Down-regulation of this decay process can increase the life expectancy of a memory and may eventually prevent its loss. Memory interference usually occurs during certain (...) active processing phases, such as encoding and retrieval, and will be stronger in brain areas with minimal sensory integration and less pattern separation. In areas with efficient pattern separation, such as the hippocampus, interference-driven forgetting will be minimal, and, consequently, decay will cause most forgetting. (shrink)

Theories of spatial cognition are derived from many sources. Psychologists are concerned with determining the features of the mind which, in combination with external inputs, produce our spatialized experience. A review of philosophical and other approaches has convinced us that the brain must come equipped to impose a three-dimensional Euclidean framework on experience – our analysis suggests that object re-identification may require such a framework. We identify this absolute, nonegocentric, spatial framework with a specific neural system centered in the hippocampus.A (...) consideration of the kinds of behaviours in which such a spatial mapping system would be important is followed by an analysis of the anatomy and physiology of this system, with special emphasis on the place-coded neurons recorded in the hippocampus of freely moving rats. A tentative physiological model for the hippocampal cognitive map is proposed. A review of lesion studies, in tasks as diverse as discrimination learning, avoidance, and extinction, shows that the cognitive map notion can adequately explain much of the data.The model is extended to humans by the assumption that spatial maps are built in one hemisphere, semantic maps in the other. The latter provide a semantic deep structure within which discourse comprehension and production can be achieved. Evidence from the study of amnesic patients, briefly reviewed, is consistent with this extension. (shrink)

How well does memory work, how accurate is it, and can we tell when someone is reporting an accurate memory? Can we distinguish a true memory from a false one? Can memories be selectively enhanced, or erased? Are memories altered by emotion, by stress, by drugs? These questions and more are addressed by Memory and Law, which aims to present the current state of knowledge among cognitive and neural scientists about memory as applied to legal settings.

Aggleton & Brown rightly point out the shortcomings of the medial temporal lobe hypothesis as an approach to anterograde amnesia. Their broader perspective is a necessary corrective, and one hopes it will be taken very seriously. Although they correctly note the dangers of conflating recognition and recall, they themselves make a similar mistake in discussing familiarity; we suggest an alternative approach. We also discuss implications of their view for an analysis of retrograde amnesia. The notion that there are two routes (...) by which the hippocampus can reactivate neuronal ensembles in the neocortex could help us understand some currently puzzling facts about the dynamics of memory consolidation.

In this response to commentaries on our target article, we highlight and clarify a variety of issues and respond to several comments, challenges, and misconceptions. Topics covered include the mechanisms of enduring change, the nature of memory, the conditions in which memories are updated, the role of emotional arousal in change, and current limitations in our understanding of the neural basis of change in psychotherapy. It is our hope that through research stimulated by this exchange the latter may be advanced.

Since Freud, clinicians have understood that disturbing memories contribute to psychopathology and that new emotional experiences contribute to therapeutic change. Yet, controversy remains about what is truly essential to bring about psychotherapeutic change. Mounting evidence from empirical studies suggests that emotional arousal is a key ingredient in therapeutic change in many modalities. In addition, memory seems to play an important role but there is a lack of consensus on the role of understanding what happened in the past in bringing about (...) therapeutic change. The core idea of this paper is that therapeutic change in a variety of modalities, including behavioral therapy, cognitive-behavioral therapy, emotion-focused therapy, and psychodynamic psychotherapy, results from the updating of prior emotional memories through a process of reconsolidation that incorporates new emotional experiences. We present an integrated memory model with three interactive components – autobiographical (event) memories, semantic structures, and emotional responses – supported by emerging evidence from cognitive neuroscience on implicit and explicit emotion, implicit and explicit memory, emotion-memory interactions, memory reconsolidation, and the relationship between autobiographical and semantic memory. We propose that the essential ingredients of therapeutic change include: (1) reactivating old memories; (2) engaging in new emotional experiences that are incorporated into these reactivated memories via the process of reconsolidation; and (3) reinforcing the integrated memory structure by practicing a new way of behaving and experiencing the world in a variety of contexts. The implications of this new, neurobiologically grounded synthesis for research, clinical practice, and teaching are discussed. (shrink)

We consider Walker's thorough review in the context of thinking about future research on the relation between sleep and memory. We first address methodological issues including type of memory and sleep-stage dependency. We suggest a broader investigation of potential signaling molecules that may be critical to sleep-related consolidation. A brief review of the importance of the stress hormone cortisol illustrates this point.

This chapter examines the role played by derogatory terms (e.g., ‘inyenzi’ or cockroach, ‘inzoka’ or snake) in laying the social groundwork for the genocide of the Tutsi in Rwanda in 1994. The genocide was preceded by an increase in the use of anti-Tutsi derogatory terms among the Hutu. As these linguistic practices evolved, the terms became more openly and directly aimed at Tutsi. Then, during the 100 days of the genocide, derogatory terms and coded euphemisms were used to direct killers (...) to their victims. Understanding these speech acts helps to illuminate the important ways that power is enacted through discourse, how speech acts can prepare the way for physical and material acts, and how speech generates permissions for actions hitherto uncountenanced. Studying the role of speech acts and linguistic practices in laying the groundwork of the genocide illuminates how patterns of speech acts become linguistic practices that constitute permissibility conditions for non-linguistic behaviors. Further, the analysis presented here helps to make sense of the view that a steady, deep, and widespread derogation of a group can be part and parcel of genocide, not only an antecedent to it.

A curious feature of Aztec philosophy is that the basic metaphysical question of the “Western” tradition cannot be formulated in their language, in Nahuatl. This did not, however, prevent the Aztecs from developing an account of 'reality', or whatever it is that might exist. The article is the first of its kind to compare the work of Aristotle on ousia (being) and the Aztecs on teotl and ometeotl. Through this analysis, it suggests that both of the Nahuatl terms are fundamental (...) for expressing the basic character of reality as process for the Aztecs. It also defends their notion as prima facia reasonable, despite its wide divergence from Aristotle's view. (shrink)

The ideal introduction for students of semantics, Lexical Meaning fills the gap left by more general semantics textbooks, providing the teacher and the student with insights into word meaning beyond the traditional overviews of lexical relations. The book explores the relationship between word meanings and syntax and semantics more generally. It provides a balanced overview of the main theoretical approaches, along with a lucid explanation of their relative strengths and weaknesses. After covering the main topics in lexical meaning, such as (...) polysemy and sense relations, the textbook surveys the types of meanings represented by different word classes. It explains abstract concepts in clear language, using a wide range of examples, and includes linguistic puzzles in each chapter to encourage the student to practise using the concepts. 'Adopt-a-Word' exercises give students the chance to research a particular word, building a portfolio of specialist work on a single word. (shrink)

Although Nietzsche's writings clearly deliver an unhealthy dose of misogyny, it must be noticed that they also contain the seeds of a deconstruction of that misogyny. This paper exposes one set of deconstructing elements of Nietzsche's works with respect to his views on women. The wider philosophical context of Nietzsche's thought provides grounds for taking seriously several passages of The Gay Science that reveal a more sympathetic understanding of women, since these passages take seriously Nietzsche's anti-dualism, his perspectivism, and his (...) early existentialist notion of the self. The destabilizing force of these passages, combined with Nietzsche's remarks about women within this philosophical context, reveals that Nietzsche's works promise more insight than many feminists have previously noted. A feminist analysis of Nietzsche's anti-dualism, perspectivism and discussion of the power of naming promises to inform contemporary feminist concerns about the importance of women's articulating our lives.

This article argues that the real promise of feminist philosophy of language is in its account of articulated normativity. Feminist philosophy of language began within a descriptivist framework, seeking to identify and root out sexist discursive practices, like naming practices that subsume women’s identity under men’s, descriptive practices that erase or undermine women’s accomplishments and presence as subjects, and so on. This approach had its limits, and led to increased attention to the discursive practices through which we articulate our experiences (...) and construct our lives. Examining the core frameworks through which feminists have analyzed the power of language to shape social reality and construct social selves, this article shows how language is normative in its production and reproduction of social norms by way of its content, forms, and constitutive discursive practices. The article urges feminists to use knowledge of the processes of articulation and legitimation to effect and explain feminist reconstitution of women as whole. (shrink)

Language matters to feminism because language is a structure of significances that governs our lives. It contains and conveys the categories through which we understand ourselves and others, and through which we become who and what we are. Our linguistic practices are constituted largely by inferences which in turn constitute or contribute to our understanding of the connections (causal and otherwise) between things. These inferential roles and patterns, which are normatively inscribed, give order and significance to the categories. Once we (...) realize that our linguistic categories reflect and are reflected by our social categories, and once we see that our discursive practices are normative, it is a short step to see language as an arena of political struggle. Feminism is, at the very least, a struggle to end sexist oppression by eradicating both the means by which oppression is carried out and the ideology that seeks that it be carried out. As our most powerful and yet nuanced symbol system, language is perhaps the primary means by which the ideology of sexism is developed and reinforced; it is not news that language is an instrument of oppression. A narrow focus on sexist semantics is of limited use to feminist philosophers, for at best such studies yield lists of past and present harms, with little more to add than “stop it, now.” The real promise of philosophy of language for feminists is an understanding of articulated normativity; by understanding how language really works, we might just understand how the rabbit of normativity gets pulled from the hat of articulation. Language is normative in its production and reproduction of social norms by way of its content, by way of its forms, and most especially by way of its constitutive discursive practices. Once we understand how women are paradoxically constituted by and yet erased from discourse, we may use what we know of these processes of articulation and legitimation to effect and explain our reconstitution as whole.

Confronting evils pulls the minds and hearts in several directions. This chapter focuses on acute cataclysmic events that shock people into awareness, or chronic corrosive evils that damage the agency and dull the attention. It also focuses on those who commit grave wrongs, or those who suffer them. Claudia Card's work has offered a steady focus on the experiences and needs of survivors of atrocities and grave wrongs. The chapter explores what Card's most recent work suggests about perpetrators, that is, (...) about the moral risks of participating in evil. Obvious atrocities include terrorism, torture, forced starvation, slavery, rape, and genocide; these each involve many grave wrongs. Card's concepts of social vitality and social death make sense of such cases, enabling us to see a perpetrator's act as a particular destruction of a survivor's world. Social vitality is important for each of us, in all phases of the lives. (shrink)

Many of our beliefs, practices, and theories reflect the assumption that the world impinges on us via our senses and, by so doing, shapes and constrains what it is reasonable to believe. And most of us engage in the practice of justifying and judging claims about ourselves and the rest of the world by reference to experience. As much to the point of the present discussion, feminist philosophers have long insisted that the questions, methods, and theories of philosophy should reflect (...) and be evaluated, at least in part, on the basis of women's experiences. Most of us are in these ways empiricists. (shrink)
