heories of embodied cognition (e.g., Perceptual Symbol Systems Theory; Barsalou, 1999, 2009) suggest that modality specific simulations underlie the representation of concepts. Supporting evidence comes from modality switch costs: participants are slower to verify a property in one modality (e.g., auditory, BLENDER-loud) after verifying a property in a different modality (e.g., gustatory, CRANBERRIES-tart) compared to the same modality (e.g., LEAVES-rustling, Pecher et al., 2003). Similarly, modality switching costs lead to a modulation of the N400 effect in event-related potentials (ERPs; Collins (...) et al., 2011; Hald et al., 2011). This effect of modality switching has also been shown to interact with the veracity of the sentence (Hald et al., 2011). The current ERP study further explores the role of modality match/mismatch on the processing of veracity as well as negation (sentences containing “not”). Our results indicate a modulation in the ERP based on modality and veracity, plus an interaction. The evidence supports the idea that modality specific simula- tions occur during language processing, and furthermore suggest that these simulations alter the processing of negation. (shrink)

In this paper we discuss an approach called grounded action cognition, which aims to provide a theory of the interdependencies between motor control and action-related cognitive processes, like perceiving an action or thinking about an action. The theory contrasts with traditional views in cognitive science in that it motivates an understanding of cognition as embodied, through application of Barsalou’s general idea of grounded cognition. To guide further research towards an appropriate theory of grounded action cognition we distinguish (...) between grounding qua acquisition and grounding qua constitution. On this basis, we distinguish three possible theoretical conceptions of grounded action cognition. In addition to these methodological and conceptual analyses, we draw on recent empirical evidence to motivate our inclination towards a particular theory. According to this theory certain representations are involved in action cognition and action perception that are not modality-specific as usually proposed by advocates of grounded cognition. Further, the evidence is in favor of our more specific theory stating that for some cognitive abilities, some motor abilites are constitutive. (shrink)

This article explores the complementary strengths and weaknesses of grounded and abstract representations in the domain of early algebra. Abstract representations, such as algebraic symbols, are concise and easy to manipulate but are distanced from any physical referents. Grounded representations, such as verbal descriptions of situations, are more concrete and familiar, and they are more similar to physical objects and everyday experience. The complementary computational characteristics of grounded and abstract representations lead to trade‐offs (...) in problem‐solving performance. In prior research with high school students solving relatively simple problems, Koedinger and Nathan (2004) demonstrated performance benefits of grounded representations over abstract representations—students were better at solving simple story problems than the analogous equations. This article extends this prior work to examine both simple and more complex problems in two samples of college students. On complex problems with two references to the unknown, a “symbolic advantage” emerged, such that students were better at solving equations than analogous story problems. Furthermore, the previously observed “verbal advantage” on simple problems was replicated. We thus provide empirical support for a trade‐off between grounded, verbal representations, which show advantages on simpler problems, and abstract, symbolic representations, which show advantages on more complex problems.

In this article, I will offer a ground-theoretic proposal to explore the so-called ‘constitution question of scientific representation’: _in virtue of_ what does a scientific model represent a part of the world? In particular, I will provide a schematic, unifying account, according to which scientific representation is grounded in both structural similarities and agent’s intentional actions. This new framework not only characterizes the nature of the dependence of scientific representation on these two sorts of factors, but also determines the (...) geometry of the dependence. Furthermore, it underlies certain intuitions which the hybrid approach to scientific representation, while acknowledging such a form of dependence but leaving its nature untouched, relies on.

What enables individuals to act together? Recent discoveries suggest that a variety of mechanisms are involved. But something fundamental is yet to be investigated. In joint action, agents represent a collective goal, or so it is often assumed. But how, if at all, are collective goals represented in joint action and how do such representations impact performance? To investigate this question we adapted a bimanual paradigm, the circle-line drawing paradigm, to contrast two agents acting in parallel with two agents (...) performing a joint action. Participants were required to draw lines or circles while observing circles or lines being drawn. The findings indicate that interpersonal motor coupling may occur in joint but not parallel action. This suggests that participants in joint actions can represent collective goals motorically. (shrink)

I give a semantic characterisation of a system for the logic of grounding similar to the system introduced by Kit Fine in his “Guide to Ground”, as well as a semantic characterisation of a variant of that system which excludes the possibility of what Fine calls ‘zero-grounding’.

This dissertation investigates how art, truth, and politics are tightly integrated in Raphael's historical narratives in the Stanza d'Eliodoro. ;The first chapter argues for the importance of paying careful attention to pictorial structure--that close analysis of painting can make a strong contribution to the social history of art. The second chapter begins this interpretive path. It first describes the room's decorative ensemble as a whole and how the histories are located within its complex figurative scheme. Then, drawing upon Martin Heidegger's (...) analysis of postmedieval processes of Vorstellung, it defines the pictorial narratives themselves as representations and concludes that as pictorial representations these narratives appear unable to ground the truth of sacred history. ;Chapter 3 focuses on the Expulsion of Heliodorus, a mural replete with self-referential models of both its own mode of authorship and mode of reception. These self-referential cues help define what it means for the Heliodorus to be not only a pictorial representation but more extensively a work of art. It is Raphael's art of representation that shows forth and validates the metaphysical truth of papal history. ;The latter part of Chapter 3 and all of Chapter 4 offer readings of the Heliodorus as well as the three other histories--the Liberation of St. Peter, Mass at Bolsena, and Repulse of Attila--construing them as theologico-political narratives of the divinity of papal power. All four histories express at the level of narrative form the dilemma of the papacy's contemporary political trajectory only for this predicament to find imaginative "resolution" through the movement of the narrative action. This chapter expounds upon the configurations of historical time in the decorative scheme and how this projects the political unconscious of papal desire. Yet the fifth and final chapter concludes that the Eliodoro narratives are not simply collective wishfulfillments but more properly public symbols that rhetorically address a beholder so to persuade him to accept as true the papacy's desired self-image of its own historical mission. Raphael's art of representation was essential towards this end. (shrink)

We explore in this paper the relation between activities, communication channels and media, and common ground building in global teams. We define re-representation as a sequence of representations of the same concept using different communication channels and media. We identified the re - representation technique to build common ground that is used by team members during multimodal and multimedia communicative events in cross-disciplinary, geographically distributed settings. Our hypotheses are as follows: (1) Significant sources of information behind decisions and request (...) for actions are embedded within the fabric of communicative events in which participants use both informal and formal media to express their ideas. Capturing these information sources can facilitate common ground building and accelerate the execution of action requests. (2) Re-representations of concepts, i.e., sequences of representations using diverse media and communication channels, mediate and accelerate common ground building. (3) The use of intra- or interdisciplinary re-representations correlates with high team performance, i.e., effective team process and high product quality. We used AEC Global Teamwork course offered in 2008–2009 as the testbed for our study to validate our hypothesis. (shrink)

Representation theorems are often taken to provide the foundations for decision theory. First, they are taken to characterize degrees of belief and utilities. Second, they are taken to justify two fundamental rules of rationality: that we should have probabilistic degrees of belief and that we should act as expected utility maximizers. We argue that representation theorems cannot serve either of these foundational purposes, and that recent attempts to defend the foundational importance of representation theorems are unsuccessful. As a result, we (...) should reject these claims, and lay the foundations of decision theory on firmer ground. (shrink)

The two traditional justifications for bicameralism are that a second legislative chamber serves a legislative-review function (enhancing the quality of legislation) and a balancing function (checking concentrated power and protecting minorities). I furnish here a third justification for bicameralism, with one elected chamber and the second selected by lot, as an institutional compromise between contradictory imperatives facing representative democracy: elections are a mechanism of people’s political agency and of accountability, but run counter to political equality and impartiality, and are insufficient (...) for satisfactory responsiveness; sortition is a mechanism for equality and impartiality, and of enhancing responsiveness, but not of people’s political agency or of holding representatives accountable. Whereas the two traditional justifications initially grew out of anti-egalitarian premises (about the need for elite wisdom and to protect the elite few against the many), the justification advanced here is grounded in egalitarian premises about the need to protect state institutions from capture by the powerful few and to treat all subjects as political equals. Reflecting the “political” turn in political theory, I embed this general argument within the institutional context of Canadian parliamentary federalism, arguing that Canada’s Senate ought to be reconstituted as a randomly selected citizen assembly.

Moving deftly among literary and visual arts, as well as the modern critical canon, Christopher Prendergast's book explores the meaning and value of representation as both a philosophical challenge (What does it mean to create an image that "stands for" something absent?) and a political issue (Who has the right to represent whom?). _The Triangle of Representation_ raises a range of theoretical, historical, and aesthetic questions, and offers subtle readings of such cultural critics as Raymond Williams, Paul de Man, Edward (...) Said, Walter Benjamin, and Hélène Cixous, in addition to penetrating investigations of visual artists like Gros, Ingres, and Matisse and significant insights into Proust and the onus of translating him. Above all, Prendergast's work is a striking display of how a firm grounding in theory is essential for the exploration of art and literature. (shrink)

Despite its centrality in the philosophy of cognitive science, there has been little prior philosophical work engaging with the notion of representation in contemporary NLP practice. This paper attempts to fill that lacuna: drawing on ideas from cognitive science, I introduce a framework for evaluating the representational claims made about components of neural NLP models, proposing three criteria with which to evaluate whether a component of a model represents a property and operationalising these criteria using probing classifiers, a popular analysis (...) technique in NLP (and deep learning more broadly). The project of operationalising a philosophically-informed notion of representation should be of interest to both philosophers of science and NLP practitioners. It affords philosophers a novel testing-ground for claims about the nature of representation, and helps NLPers organise the large literature on probing experiments, suggesting novel avenues for empirical research.

A promising strategy for defending the role that representation plays in explanations of cognition frames the concept in terms of internal models or map‐like mechanisms. “Structural representation” offers an account of representation that is grounded in well‐specified, empirical criteria. However, anti‐representationalists continue to press the issue of how to account for the paradigmatic semantic properties of representation at the subpersonal level. In this paper, I offer an account of how the proponent of structural representation should think about content. There (...) are really two problems of content any account of representation must overcome: the “hard problem of content” and the “content determination problem.” I argue that the structural representation account has the resources to provide a naturalistically respectable notion of content that overcomes both problems.

The "teleosemantic" program is part of the attempt to give a naturalistic explanation of the semantic properties of mental representations. The aim is to show how the internal states of a wholly physical agent could, as a matter of objective fact, represent the world beyond them. The most popular approach to solving this problem has been to use concepts of physical correlation with some kinship to those employed in information theory (Dretske 1981, 1988; Fodor 1987, 1990). Teleosemantics, which tries (...) to solve the problem using a concept of biological function, arrived in the mid 1980s with ground-breaking works by Millikan (1984) and Papineau (1984, 1987).¹.

Embodied cognitive theories predict that linguistic conceptual representations are grounded and continually represented in real world, sensorimotor experiences. However, there is an on-going debate on whether this also holds for abstract concepts. Grammar is the archetype of abstract knowledge, and therefore constitutes a test case against embodied theories of language representation. Former studies have largely focussed on lexical-level embodied representations. In the present study we take the grounding-by-modality idea a step further by using reaction time (RT) data (...) from the linguistic processing of nominal classifiers in Chinese. We take advantage of an independent body of research, which shows that attention in hand space is biased. Specifically, objects near the hand consistently yield shorter RTs as a function of readiness for action on graspable objects within reaching space, and the same biased attention inhibits attentional disengagement. We predicted that this attention bias would equally apply to the graspable object classifier but not to the big object classifier. Chinese speakers (N = 22) judged grammatical congruency of classifier-noun combinations in two conditions: graspable object classifier and big object classifier. We found that RTs for the graspable object classifier were significantly faster in congruent combinations, and significantly slower in incongruent combinations, than the big object classifier. There was no main effect on grammatical violations, but rather an interaction effect of classifier type. Thus, we demonstrate here grammatical category- specific effects pertaining to the semantic content and by extension the visual and tactile modality of acquisition underlying the acquisition of these categories. We conclude that abstract grammatical categories are subjected to the same mechanisms as general cognitive and neurophysiological processes and may therefore be grounded. (shrink)

In this paper we discuss the representational realist stance as a pluralist ontic approach to inter-theoretic relationships. Our stance stresses the fact that physical theories require the necessary consideration of a conceptual level of discourse which determines and configures the specific field of phenomena discussed by each particular theory. We will criticize the orthodox line of research which has grounded the analysis about QM in two metaphysical presuppositions —accepted in the present as dogmas that all interpretations must follow. We (...) will also examine how the orthodox project of "bridging the gap" between the quantum and the classical domains has constrained the possibilities of research, producing only a limited set of interpretational problems which only focus in the justification of "classical reality" and exclude the possibility of analyzing the possibilities of non-classical conceptual representations of QM. The representational realist stance introduces two new problems, namely, the superposition problem and the contextuality problem, which consider explicitly the conceptual representation of orthodox QM beyond the mere reference to mathematical structures and measurement outcomes. In the final part of the paper, we revisit, from a representational realist perspective, the quantum to classical limit and the orthodox claim that this inter-theoretic relation can be explained through the principle of decoherence.

Carrie Jenkins presents a new account of arithmetical knowledge, which manages to respect three key intuitions: a priorism, mind-independence realism, and empiricism. Jenkins argues that arithmetic can be known through the examination of empirically grounded concepts, non-accidentally accurate representations of the mind-independent world.

The representation of objects and faces by neurons in the temporal lobe visual cortical areas of primates has the property that the neurons encode relatively independent information in their firing rates. This means that the number of stimuli that can be encoded increases exponentially with the number of neurons in an ensemble. Moreover, the information can be read by receiving neurons that perform just a synaptically weighted sum of the firing rates being received. Some ways in which these representations (...) become grounded in the world are described. The issue of syntactic binding in representations, and of its value for a higher order thought system, is discussed. (shrink)

Our contribution aims at individuating a valid philosophical strategy for a fruitful confrontation between human and artificial representation. The ground for this theoretical option resides in the necessity to find a solution that overcomes, on the one side, strong AI (i.e. Haugeland) and, on the other side, the view that rules out AI as explanation of human capacities (i.e. Dreyfus). We try to argue for Analytic Pragmatism (AP) as a valid strategy to present arguments for a form of weak AI (...) and to explain a notion of representation common to human and artificial agents.

This chapter discusses recent attempts to clarify the notion of practical representation and its theoretical fruitfulness. The ultimate goal is not just to show that intellectualists are on good grounds when they appeal to practical representation in their theories of know-how. Rather, it is to argue that ​ any plausible theory of skill and know-how has to appeal to the notion of practical representation developed here. §1 explains the notion of a mode of presentation and introduces practical modes of presentation. (...) §2 illustrates practical representation by discussing models of motor control in current theories of sensori-motor psychology; §3 puts forward an argument for positing practical representation. §4 goes from practical non-conceptual representations to practical conceptual representations — to practical concepts. §5 concludes.

This paper centers around the notion that internal, mental representations are grounded in structural similarity, i.e., that they are so-called S-representations. We show how S-representations may be causally relevant and argue that they are distinct from mere detectors. First, using the neomechanist theory of explanation and the interventionist account of causal relevance, we provide a precise interpretation of the claim that in S-representations, structural similarity serves as a “fuel of success”, i.e., a relation that is (...) exploitable for the representation using system. Then, we discuss crucial differences between S-representations and indicators or detectors, showing that—contrary to claims made in the literature—there is an important theoretical distinction to be drawn between the two.

A number of philosophers have recently argued for acknowledging non-augmented partial grounds, partial grounds that are not parts of full grounds. This paper shows how non-augmented partial grounds can be straightforwardly modelled within the framework of generalised identity. I argue that my proposal answers questions concerning the connections between partial grounding, full grounding, and nothing-over-and-aboveness in a motivated way. In this context, I propose and discuss a way to spell out nothing-over-and-aboveness in terms of generalised identity that does justice to (...) the claim that the fully grounded is nothing over and above its full grounds. It will turn out that the related question whether partial grounding and nothing-over-and-aboveness yield full grounding pertains to considerations concerning how finely factual content is individuated. The relationship between non-augmented partial grounding and nothing-over-and-aboveness crucially depends on whether one works with a representational or a worldly notion of grounding and how coarsely grained one takes worldly grounds to be.

According to the popular Grounded Cognition Model (GCM), the sensory and motor features of concepts, including word meanings, are stored directly within neural systems for perception and action. More precisely, the core claim is that these concrete conceptual features reuse some of the same modality-specific representations that serve to categorize experiences involving the relevant kinds of objects and events. Research in semantic typology, however, has shown that word meanings vary significantly across the roughly 6500 languages in the world. (...) I argue that this crosslinguistic semantic diversity has significant yet previously unrecognized theoretical consequences for the GCM. In particular, to accommodate the typological data, the GCM must assume that the concrete features of word meanings are not merely stored within sensory/motor brain systems, but are represented there in ways that are, to a nontrivial degree, language-specific. Moreover, it must assume that these conceptual representations are also activated during the nonlinguistic processing of the relevant kinds of objects and events (e.g., during visual perception and action planning); otherwise, they would not really be grounded, which is to say, embedded inside sensory/motor systems. Crucially, however, such activations would constitute what is traditionally called linguistic relativity—that is, the influence of language-specific semantic structures on other forms of cognition. The overarching aim of this paper is to elaborate this argument more fully and explore its repercussions. To that end, I discuss in greater detail the key aspects of the GCM, the evidence for crosslinguistic semantic diversity, pertinent work on linguistic relativity, the central claim that the GCM entails linguistic relativity, some initial supporting results, and some important limitations and future directions.

In this paper, we introduce a novel difficulty for teleosemantics, viz., its inability to account for what we call unexploited content—content a representation has, but which the system that harbors it is currently unable to exploit. In section two, we give a characterization of teleosemantics. Since our critique does not depend on any special details that distinguish the variations in the literature, the characterization is broad, brief and abstract. In section three, we explain what we mean by unexploited content, and (...) argue that any theory of content adequate to ground representationalist theories in cognitive science must allow for it.1 In section four, we show that teleosemantic theories of the sort we identify in section two cannot accommodate unexploited content, and are therefore unacceptable if intended as attempts to ground representationalist cognitive science. Finally, in section five, we speculate that the existence and importance of unexploited content has likely been obscured by a failure to distinguish representation from indication, and by a tendency to think of representation as reference.

In this article, I take on a classic objection to Kant’s arguments in the Antinomy of Pure Reason: that the arguments are question-begging, as they draw illicit inferences from claims about representation to claims about reality. While extant attempts to vindicate Kant try to show that he does not make such inferences, I attempt to vindicate Kant’s arguments in a different way: I show that, given Kant’s philosophical backdrop, the inferences in question are not illicit. This is because the transcendental (...) realists that Kant was arguing against have certain philosophical commitments about the nature of ground which, if true, warrant the inferences that Kant draws. This historical corrective not only allows us to better understand Kant’s own thinking in the Antinomies but it also has important upshots for our understanding of Kant’s transcendental idealism.

Some views articulate reality's hierarchical structure using relations from the fundamental to representations of reality. Other views instead use relations from the fundamental to constituents of non-representational reality. This paper argues against the first kind of view.

According to a currently popular approach to the analysis of phenomenal character, the phenomenal character of an experience is entirely determined by, and is in fact identical with, the experience's representational content. Two underlying assumptions motivate this approach to phenomenal character: (1) that conscious experiences are diaphanous or transparent, in the sense that it is impossible to discern, via introspection, any intrinsic features of an experience of x that are not experienced as features of x, and (2) that the immediate (...) objects of consciousness are not objects per se, but rather properties. This paper explores these assumptions, advancing the thesis that each is rejectable on phenomenological grounds. (shrink)

The computational metaphor for mind is still the central guiding idea in cognitive science despite many insightful and well-founded rejections of it. There is good reason for its staying power: when we are at our cognitive best, we reason about our world with our concepts. But the challengers are right, I argue, in insisting that no reductive account of that capacity is forthcoming. Here I describe an externalist account that grounds representations in organism-level engagement with its environment, not in (...) its neural activity. (shrink)

What can we learn about the existence of non-physical entities from close inquiry into special kinds of experiences? Contemporary analytic philosophy has sometimes studied mystic experiences as evidence for the existence of such entities. The article is organized as follows: first, I discuss several distinctions that seem to me to play substantive roles in philosophizing about such experiences. I will then offer and criticize two arguments that support the significance of the experiences. The arguments do not show whether a non-physical (...) entity does or does not exist; they highlight a philosophical framework that can be beneficial to a variety of different approaches. Based on a heuristic strategy, the arguments will focus on the possibility/impossibility of objective representation of non-physical entities. They invite the reader to reflect on deeper philosophical grounds necessary for evaluating any positive or negative claims about the significance/insignificance of such experiences. The first argument rests on contemporary theories and assumptions. The second argument will use notions that drive from Classic Arabic-Persian Philosophy. (shrink)

The book from which these sections are excerpted is concerned with the prospects for assimilating the study of human intelligence and its products to the natural sciences through the investigation of cognitive structures, understood as systems of rules and representations that can be regarded as These mental structui′es serve as the vehicles for the exercise of various capacities. They develop in the mind on the basis of an innate endowment that permits the growth of rich and highly articulated structures (...) along an intrinsically determined course under the triggering and partially shaping effect of experience, which fixes parameters in an intricate system of predetermined form. It is argued that the mind is modular in character, with a diversity of cognitive structures, each with its specific properties arid principles. Knowledge of language, of the behavior of objects, and much else crucially involves these mental structures, and is thus not characterizable in terms of capacities, dispositions, or practical abilities, nor is it necessarily grounded in experience in the standard sense of this term.

This paper argues that the contrast between direct and representative democracy is less important than that between simple majoritarianism and deliberative i.e., public reason centred, democracy, as only the latter is sufficiently sensitive to the problem of domination.

Both symbolic representation and delegate democracy are rejected in favour of substantive (...) measures to formalise communication between voters and representatives and permit the formal contestation of political decision on the ground that these will provide stronger defences against domination within the political system.

Recent debates about mathematical ontology are guided by the view that Platonism's prospects depend on mathematics' explanatory role in science. If mathematics plays an explanatory role, and in the right kind of way, this carries ontological commitment to mathematical objects. Conversely, the assumption goes, if mathematics merely plays a representational role then our world-oriented uses of mathematics fail to commit us to mathematical objects. I argue that it is a mistake to think that mathematical representation is necessarily ontologically innocent and (...) that there is an argument from mathematics' representational capacity to Platonism. Given that it is common ground between the Platonist and nominalist that mathematics plays a representational role in science, this representationalist argument is to be preferred over the explanatory, or enhanced, indispensability argument.

This paper analyses self-declared aims and representation of dementia patient organizations and advocacy groups in relation to two recent upheavals: the critique of social stigmatization and biomedical research focusing on prediction. Based on twenty-six semi-structured interviews conducted in 2016–2017 with members, service recipients, and board representatives of POs in Germany and Israel, a comparative analysis was conducted, based on a grounded theory approach, to detect emerging topics within and across the POs and across national contexts. We identified a heterogeneous (...) landscape, with the only Israeli PO focusing strongly on caretakers, whereas in Germany several POs claim to represent this patient collective. Shared aims of all POs were fighting social stigma, balancing the loss of patients’ individual autonomy, and the well-being of caretakers. By highlighting the emergence of new groups of dementia self-advocacy against the more traditional advocacy by others, this study highlights how advocacy and representation in the context of AD are embedded in the discursive context of stigmatization and revised disease conception. Future developments in early diagnosis and prediction of dementia, with more affected people likely to conduct dementia self-advocacy, might challenge existing representation structures even more.

The case of pain asymbolia is a case study that provides evidence of the mechanisms underlying the relationship between bodily experience, affective experience, and self-awareness. On one account pain asymbolia is the result of an affective deficit. Sensory signals of bodily damage are not associated with characteristic negative affect. Cochrane endorses this account as part of his version of a “conceptual act” theory of affective experience. In contrast, I propose an active inference account of affect in general and pain asymbolia (...) in particular. In the active inference framework the self is inferred as the endogenous cause of bodily and affective experience in the process of organismic regulation. This preserves Cochranes ambition to ground affect in bodily regulation but avoids the problem for affective deficit accounts of asymbolia that cannot do justice to the neural correlates. (shrink)

The thesis concerns itself with the selection constraints governing the basic distributional patterns of five complement constructions in English--the bare clause, the that-clause, the interrogative, the concealed question construction and the exclamative complement--across a wide array of knowledge, belief and communication predicates. The relevant distributional phenomena--which predicates are capable of embedding which complement types--have traditionally been captured by stipulative grammatical markings such as subcategorization frames, semantic selection frames and case-theoretic lexical markings. These theoretical tools, even to the extent that they (...) successfully reduplicate the observed phenomena, are of no explanatory value, as they do not derive the different behavioral patterns from some independently established properties of the embedding predicates or their complements. In the thesis, I present an epistemically-based theory, which attempts to derive the relevant distributional phenomena, including those traditionally assumed to reflect hard-core syntactic idiosyncrasies, from a linguistic-epistemic theory of knowledge, belief and communication. ;The theory is based on a lexical-semantic analysis of the embedding predicates, according to which they denote ternary relations between agents, objects of attitude and objects of representation. Thus, to give an example, the predicate think denotes a ternary relation between a thinker, a thought mentally represented by the thinker, and a proposition expressed by the thought and believed by the thinker to be true. This analysis, developed on linguistic grounds for linguistic purposes, echoes some of the recent insights in the philosophy of mind, especially Crimmins . Coupled with a theory of the meanings of the different complement types--partially based on the formal semantic insights of Karttunen , Groenedijk and Stokhof and Ginzburg --this account derives the distributional patterns from simple considerations of semantic compatibility: those predicates which are capable of embedding a certain complement type are exactly those whose lexical semantics is compatible with the semantics of the complement. ;Some of the distributional patterns discussed in the thesis, especially the one involving concealed questions, have traditionally been taken to provide empirical support for the hypothesis of the autonomy of syntactic representations . The analysis presented in this thesis reveals the dramatic extent to which the semantics and the syntax of lexical selection are transparent to each other, and thus implies, at least with respect to the core domain of lexical selection, that the autonomy hypothesis is empirically unjustified.

In this reply we claim that, contra Dreyfus, the kinds of skillful performances Dreyfus discusses _are_ representational. We explain this proposal, and then defend it against an objection to the effect that the representational notion we invoke is a weak one countenancing only some global state of an organism as a representation. According to this objection, such a representation is not a robust, projectible property of an organism, and hence will gain no explana- tory leverage in cognitive scientific explanations. We (...) argue on conceptual and empirical grounds that the representations we have identified are not weak unprojectible global states of organisms, but instead genuinely explanatory representational parts of persons.

Mathematics plays a central role in much of contemporary science, but philosophers have struggled to understand what this role is or how significant it might be for mathematics and science. In this book Christopher Pincock tackles this perennial question in a new way by asking how mathematics contributes to the success of our best scientific representations. In the first part of the book this question is posed and sharpened using a proposal for how we can determine the content of (...) a scientific representation. Several different sorts of contributions from mathematics are then articulated. Pincock argues that each contribution can be understood as broadly epistemic, so that what mathematics ultimately contributes to science is best connected with our scientific knowledge. In the second part of the book, Pincock critically evaluates alternative approaches to the role of mathematics in science. These include the potential benefits for scientific discovery and scientific explanation. A major focus of this part of the book is the indispensability argument for mathematical platonism. Using the results of part one, Pincock argues that this argument can at best support a weak form of realism about the truth-value of the statements of mathematics. The book concludes with a chapter on pure mathematics and the remaining options for making sense of its interpretation and epistemology. Thoroughly grounded in case studies drawn from scientific practice, this book aims to bring together current debates in both the philosophy of mathematics and the philosophy of science and to demonstrate the philosophical importance of applications of mathematics.

Delusion is one of the most intriguing psychopathological phenomena and its conceptualization remains the subject of genuine debate. Claims that it is ill-defined, however, are typically grounded on essentialist expectations that a given definition should capture the core of every instance acknowledged as delusion in the clinical setting.

Empirical studies indicate that analogy consists of two main processes: retrieval and mapping. While current theories and models of analogy have revealed much about the mainly structural constraints that govern the mapping process, the similarities that underpin the correspondences between individual representational elements and drive retrieval are understood in less detail. In existing models symbol similarities are externally defined but neither empirically grounded nor theoretically justified. This paper introduces a new model (EMMA: the environmental model of analogy) which relies (...) on co‐occurrence information provided by LSA (Latent Semantic Analysis; Landauer & Dumais, 1997) to ground the relations between the symbolic elements aligned in analogy. LSA calculates a contextual distribution for each word encountered in a corpus by counting the frequency with which it co‐occurs with other words. This information is used to define a model that locates each word encountered in a high‐dimensional space, with relations between elements in this space representing contextual similarities between words. A series of simulation experiments demonstrate that the environmental approach to semantics embodied in LSA can produce appropriate patterns of analogical retrieval, but that this semantic measure is not sufficient to model analogical mapping. The implications of these findings, both for theories of representation in analogy research and more general theories of semantics in cognition, are explored. (shrink)

This article attempts to make a conceptual and epistemological junction between human learning and machine learning. I will be concerned with specifying and analysing the structure of concepts in the common ground between a concept-based human learning theory and a concept-based machine learning paradigm. I will focus on (i) humans’ conceptual representations in the framework of constructivism (as an educational theory of learning and model of knowing) and constructionism (as a theory for conceptualising learning) and (ii) concept representations (...) in the framework of inductive concept learning (as an inductive machine learning paradigm). The results will support figuring out the most significant key points for constructing a conceptual linkage between a human learning theory and a machine learning paradigm. Accordingly, I will construct a conceptual ground for expressing and analysing concepts in the common ground of human and informatics sciences and in the context of human-machine interplays.

This article illustrates the ways in which visual representations construct the meanings of norms governing the spaces we commonly inhabit. I argue that norms regulating public spaces such as streets, parks, plazas, and beaches arise within the process of conceiving tourist representations of space that benefit hegemonic groups in society. My argument is empirically grounded on evidence from a case study on public space regulation in Acapulco, Mexico. By means of a semiotic analysis of tourist materials such (...) as maps and postcards, I show that images related to tourism represent urban space in a way that includes some elements and excludes others. By doing so, they portray a very specific image of the city and its public spaces. Because representations of space are performed upon the entire society, the imagery reproduced by tourist materials is part of the expectations that surround social actors’ actions. This is one of the mechanisms through which the tourism industry influences the regulation of public spaces. (shrink)

There are two main approaches in the phenomenological understanding of the unconscious. The first explores the intentional theory of the unconscious, while the second develops a non-representational way of understanding consciousness and the unconscious. This paper aims to outline a general theoretical framework for the non-representational approach to the unconscious within the phenomenological tradition. In order to do so, I focus on three relevant theories: Maurice Merleau-Ponty’s phenomenology of perception, Thomas Fuchs’ phenomenology of body memory, and Edmund Husserl’s phenomenology of (...) affectivity. Both Merleau-Ponty and Fuchs understand the unconscious as a “sedimented practical schema” of subjective being in the world. This sedimented unconscious contributes to the way we implicitly interpret reality, fill in the gaps of uncertainty, and invest our social interactions with meaning. Husserl, however, approaches the unconscious in terms of affective non-vivacity, as a sphere of sedimentation and the horizon of the distant past which stays affectively connected to the living present. Drawing on these ideas, I argue that these two accounts can reinforce one another and provide the ground for a phenomenological understanding of the unconscious in terms of the horizontal dimension of subjective experience and a non-representational relation to the past.
